Night's Watch 2: Dark Potential

Chapter 7 Silver Needle Baby Girl
The light that blinds us is our darkness.The dawn will only break when we are awake.

Beside the isolation cabinet of the physical evidence testing laboratory of the Nan'an Public Security Bureau, Ling Mo was concentrating on studying the black peony-patterned women's knitted jacket.

He sat outside the isolation cabinet, stretched his hands into the isolation cabinet through the operation hole, carefully pulled a part of the sweater apart, and then used tweezers to grab a small piece of black silk from the yarn of the sweater, and placed it on the flat white on paper.

There are already a dozen black threads on the white paper.

At that time, the police did a lot of work on the important physical evidence in Cao Yun's case - this women's knitted coat, especially the investigation around the owner of this knitted coat.However, after the DNA extraction work carried out by Fu Ruxi and her team, no clearly identifiable DNA genotype was extracted from the clothes.

Therefore, the police have internal disputes about this dress.Some people think that this is a new dress, and it has been worn for a short time, so there is no DNA adhesion; some people think that as long as the neckline and cuffs of the clothes are easily adhered to DNA, DNA will not be found on this coat. It is also very normal.

Later, Nie Zhixuan and Fu Ruxi found a piece of black silk in the wool hole of the knitted sweater.

As for what this black thread is, Nie Zhixuan also put in a lot of effort.Later, under a microscope, Nie Zhixuan discovered that the black silk is a structure with cortex and medulla, surrounded by imbricate hair cuticles, thus confirming that this small black silk should be hair.The hair is cylindrical, with thin cuticle scales, fine patterns on the surface, uneven arrangement, and various intersecting edges. It is different from animal hair and other parts of human hair, so Nie Zhixuan determined that this should be the end of human hair.

Unfortunately, with the current DNA technology, it is impossible to extract the DNA genotype from the hair without hair follicles.Therefore, this section of hair cannot be used to confirm Cao Yun's suspicion of committing the crime through DNA testing.

However, it is not new clothes, but old clothes that have been washed. This can be regarded as an indirect proof that no one bought a new clothes to disguise the crime process and divert the attention of the police.Therefore, the police believe that the authenticity of Cao Yun throwing away the clothes in the dressing room is relatively high.

After the Cao Yun case was declared closed, the dress, together with other evidence in the case, was handed over to the evidence vault of the Nan'an police.

Based on previous inferences, Ling Mo believes that there are quite a lot of strange things in the murder of "Ghost Rider", and it is very likely that someone else is using Cao Yun to commit the crime.From different angles, the invisible information Ling Mo sees is different from that of the police: If this is really the case, since the clothes have been carefully cleaned, it means that the clothes must not belong to Cao Yun himself.Otherwise, since she was going to be blamed, the more DNA left, the more meaningful it would be.

Therefore, all the clues on this dress may be useful in finding the real culprit.Ling Mo had gone to the Evidence Preservation Center, retrieved the clothes, and conducted a more careful observation.He found that there was not only a small piece of hair mixed in the clothes, but also a lot of hair.Helpless, hair DNA cannot be made, so any other ideas can only be given up temporarily.

It wasn't until the police captured Gu Xing that Ling Mo accidentally saw the many hair fragments stuck to his face, and his inspiration was suddenly stimulated, so he rushed to the Nan'an Public Security Bureau's Evidence Preservation Center impatiently, and retrieved this A knitted sweater that had been dusty, borrowed Fu Ruxi's laboratory to work.

The hair itself is thin and light, and there is only a small part of the hair, so it is easier to be carried away by the flowing air.So, in the isolation cabinet where the air was completely still, Ling Mo slowly pulled out all the hairs caught in the yarn holes of the knit sweater one by one.Although the current Ling Mo didn't know if it was meaningful for him to do so, but there was a belief supporting him that he must finish this matter.

It is very difficult to find hairs in knitted sweaters that are also made of wool. In addition, the shortness of the hairs, the interference of the black sweater itself, and the inconvenience of observing through a separate cabinet make this piece Work is even more difficult.Ling Mo stopped to rub his eyes a few times, thinking that it would be great if Xiao Lang, a guy with extraordinary senses, was here. If this job is entrusted to him, it should be much easier.However, Xiao Lang is currently cooperating with the police in the surprise interrogation of Gu Xing and others, so he may not have time to help him.

Ling Mo carefully placed the white paper covered with dozens of hair fragments in a plastic transparent tray, covered it with a lid, took out the isolation cabinet, and came to the microscope.

What he has to do now is to observe what these hairs have in common and what they are different from.

Although using a microscope to observe is not Ling Mo's forte, he still tries to see the difference between each hair fragment.Some hair medulla is very thick, while others are very small; some hair cuticles are messy, and some are neatly arranged;

A smile slowly emerged from the corner of Ling Mo's mouth.

"If my mother hadn't told me, I really couldn't find you!" Xiao Lang walked behind Ling Mo at some point and patted him on the shoulder suddenly.

"Why are you walking silently?" Ling Mo was startled.

"Because I have good hearing, I try to walk as lightly as possible, and I can't hear it in other people's ears." Xiao Lang said proudly, "Do you know? Gu Xingquan has given up, and the confession process is exactly the same as our analysis! Now I I think we won’t be called Night Watchers in the future, we’ll be called Detective Alliance!”

"Don't get carried away." Ling Mo said, "Papa Fu said that the Night Watchman is not just an organization name, but also a belief and belief."

"What is this thing?" Xiao Lang picked up the tray on the table and asked.The air blown by Xiao Lang's words pushed the hair fragments in the tray closer to one side.

"Hey, don't blow away all the physical evidence." Ling Mo grabbed the tray.

"Is this hair?" Xiao Lang said, "The thickness and color are different."

When Ling Mo heard what Xiao Lang said, he stared blankly at him and said, "If I had known that your eyes are stronger than a microscope, I wouldn't have to make such a big effort."

"You left me alone at the scene." Xiao Lang spread his hands and leaned on the seat in the evidence room, "Who knew that you ran in such a hurry to study this pile of broken hair!"

"Hair is hair, but it doesn't break." Ling Mo said with a smile, "At least it tells me that the person who killed 'Ghost Rider' should be hiding in a barber shop in disguise."

Xiao Lang glanced at the black sweater in the isolation closet, and said: "There are a lot of hairs of different shapes mixed on the same clothes, the most common ones are hairdressers, and Cao Yun has nothing to do with the styling industry. This shows that the murderer is really someone else."

"Unfortunately, there are too many practitioners in this industry, and we still can't do anything." Ling Mo silently put the knitted sweater into the evidence bag.

"The scope has been narrowed down a lot." Xiao Lang patted Ling Mo on the shoulder, "It's a big step forward from being ignorant before! However, I didn't come to talk to you about some shit. hair."

Ling Mo raised his eyes and stared at Xiao Lang curiously.

Xiao Lang laughed, and said: "Grandpa was afraid that we would be too busy, no, brother Nie found us another good job. However, before I go to pick up the job, I have to go and see my mother first."

Ling Mo immediately agreed: "It's just right, I also have something to ask Director Fu. Hey, wait a minute."

Xiao Lang looked back at Ling Mo with a puzzled expression, and Ling Mo picked up a copy of Nan'an Metropolis Daily from the laboratory desk.

"Nan'an reappeared child 'mutation' incident! Is it the fault of the vaccine again?" Douda's bold front page is eye-catching.

"What is this?" Xiao Lang poked his head to read.

"Do you still remember the toddler from Xinqiao? The one who passed out after being vaccinated." Ling Mo asked.

"Is there?" Xiao Lang rolled his eyes and thought.

"When Cao Yun was arrested, it was mentioned in the broadcast on Jack." Ling Mo reminded.

"I don't know." Xiao Lang looked blank.Ling Mo handed over the newspaper, and while Xiao Lang was reading the newspaper in a daze, he quickly browsed the news on his mobile phone.

"Hey, this news headline is too frightening. I thought it was some kind of mutation. It turns out that the child is overdeveloped." Xiao Lang waved the newspaper noncommittally, "The five-year-old child is more than 1.4 meters tall, and he is overnourished. ?”

Ling Mo looked at the phone and shook his head: "I don't think it's that simple. At the moment, the Internet is full of discussions about these two incidents. The child started to develop excessively after being vaccinated at the age of three. The five-year-old At that time, the development of secondary sex characteristics had already appeared, and even the fine hair on the body became too black and too long, which is not a normal phenomenon."

Xiao Lang spread his hands and threw the newspaper back on the table: "So everyone rushed to take their children for examination? Didn't the news also say that the investigation team did not find the problematic vaccine, and there was not enough evidence to prove that it was related to the vaccine. The matter is still under investigation. Besides, last time it was a coma, this time it was a development, are these two things related? Let's hurry to find my mother."

Ling Mo was full of doubts, but he really had nothing to say, so he followed Xiao Lang and left the laboratory.

If the eldest son is the sustenance of hope, then Xiao Lang is a happy fruit in Fu Ruxi's heart.Although Xiao Lang is about 1.8 meters tall, Fu Ruxi couldn't help but hug him when he saw him.

"Give me some face, Mom!" Xiao Lang jumped a step away, avoiding Fu Ruxi's embrace.

"I heard that you met a genetic chimera?" Fu Ruxi shook her head and smiled.

"Yes, Director Fu, you study genes, can you tell us what genes are?" Ling Mo said.

"This..." Fu Ruxi frowned and thought, "I don't know how to summarize this big concept. In short, genes support the basic structure and performance of life, and store the race, blood type, gestation, and growth of life." All the information about the process of life and apoptosis. All life phenomena such as birth, growth, decline, disease, old age, and death of organisms are related to genes.”

"Then this kind of gene chimera, the information displayed in all aspects, is it the elder brother's or the younger brother's?" Xiao Lang asked.

"Whether it is a chimera or not, different genes at specific loci [19] will show different information." Fu Ruxi said, "It has nothing to do with elder brother or younger brother."

"That is to say, our various traits and abilities are determined by specific genes. If the gene mutation is different from ordinary people, will we get superpowers?" Ling Mo asked.

"Scientists once sequenced the genes of cheetahs and found that 11 gene mutations appeared in cheetahs during generations of reproduction, which made cheetahs run faster." Fu Ruxi said, "Of course, this is just an exploratory conclusion, but this conclusion may support your thoughts."

"That is to say, with the progress of human evolution, the abilities in all aspects will become stronger and stronger?" Xiao Lang asked.

"Speaking of the word 'evolution', this is another subject." Fu Ruxi said, "Some scholars believe that the phenomenon of gene mutation and other phenomena in the process of organism development and evolution is not necessarily a kind of progress, but a kind of progress. Random phenomena, there is no progress or regression. Yan Fu also created the term "Tianyan", which is a different understanding of evolution and evolution."

"In other words, it is impossible for humans to control this evolution?" Ling Mo asked.

Fu Ruxi nodded and said: "Gene mutations can not only be spontaneous, but also induced, so now there is also the technology of gene-directed mutation, but the ability of this technology is also limited. In addition, gene mutations may be harmful to the individual, or may be harmful to the individual." Individuals are beneficial, or both, or neutral mutations that are harmless and non-beneficial. Even if there is a way to promote gene mutations, how to control such mutations to only benefit individuals?"

"In other words, it is possible to realize the idea of ​​artificially controlling genetic mutations to improve certain aspects of ability." Xiao Lang said.

"But it's hard to control." Fu Ruxi added.

"So, from the perspective of forensic science, if a gene is mutated, will it lead to a direct change in the traits of the organism?" Ling Mo said, "Is it the abnormality found in the forensic medical examination?"

"This is fine." Fu Ruxi said, "For example, cancer is caused by mutations in proto-oncogenes and tumor suppressor genes. The traits of organisms have changed. But not all gene mutations will appear on the appearance of organisms. manifest."

There was silence in the laboratory.

"What are you thinking?" Seeing Ling Mo's serious face, Xiao Lang asked.

"I think the autopsy on 'Ghost Rider' might have been a little easier." Ling Mo said.

"Hey, are you starting to dictate the forensic work?" Xiao Lang laughed, "It was a simple poisoning death, with no other injuries except my shot. What complicated autopsy work is there?"

"I think it's necessary to talk to Brother Nie." Ling Mo still insisted on his opinion.

"Our dear Brother Nie, is giving us a question in the organization! The case in front of you is important, and you can let go of your wild ideas." Xiao Lang pretended to be affectionate and wanted to hug Ling Mo's shoulders, but Ling Mo avoided.

In the large conference room of the Night Watchers Organization, Nie Zhixuan stood on the podium, typing on the keyboard with his mechanical hand.

Xiao Lang and Ling Mo walked into the conference room and saw that Fu Yuanman had already taken their seats, so they took their seats and waited for Nie Zhixuan to start introducing the case.

"This case was under the jurisdiction of my unit last year." Nie Zhixuan said, "The organization just received an order from the Criminal Investigation Bureau of the Ministry of Public Security, asking me to organize a task force to participate in this unsolved backlog of cases and assist the police in solving the case."

Having just solved a case, they started the journey of the next case without taking a break. The members of the organization did not feel tired, but listened to Nie Zhixuan's report with more energy.

"I will introduce this case according to the timeline. The first incident of this case was a report of a disappearance, and the person who reported the case was this little girl named Yin Zhaodi. All the age data are calculated based on the year of last year." Nie Zhixuan opened A diagram of family relationships.

This is a family of five.The head of the household is Yin Jie, male, 44 years old, he practiced martial arts when he was young, and now works as a security guard in a factory in the town; Children, but every time after confinement, I will go out to work in big cities, mainly to do some housekeeping services.Among the three children, Yin Zhaodi is the elder sister, 40 years old, dropped out of school after finishing junior high school, and basically does the farm work at home by herself; the second child, Yin Zhuangzhuang, is 16 years old, a boy who lives in the town and is in the first grade of junior high school; The third is an 13-month-old baby girl who has not yet registered. The family calls her Yueyue. At home, she mainly relies on Yin Jie and Yin Zhaodi to take care of her.

And what happened was the 11-month-old baby girl, Yueyue.

On August 8 last year, which was the hottest time of the year, in the early morning, Yin Zhaodi suddenly said that his sister had been stolen, and immediately searched the whole village with his father Yin Jie.After all, it was a baby girl who had just learned to walk, and it was impossible for her to run far by herself, so under the advice of the villagers, Yin Jie and Yin Zhaodi went to the local police station to report the case at noon that day.

While the police station notified the special police officers to search the surrounding area, they also investigated Yin Jie's house and investigated the basic situation of the case.

Yin Jie's family background is average, and he lives in a row of bungalows in the village.The home is a living room in the middle and wing rooms on both sides.According to Yin Zhaodi's narration, on the night of the incident, that is, the night of the 16th, Yin Zhaodi took Yueyue to sleep in the west wing room as usual, and soon fell asleep.At about three o'clock in the morning, Yin Zhaodi felt as if someone had taken Yueyue away from the window, but he thought it was a dream, so he was confused for a while.After a while, she woke up suddenly, and looked at the cradle by the window again, and Yueyue had disappeared.

At this time, Yin Zhaodi thought that it was not a dream just now, so he stepped on the window sill and jumped to the back of the house, chasing all the way, and seemed to see a black shadow running 300 meters away.Zhaodi Yin was very scared, so he went back to the house, trying to wake Yin Jie up, but Yin Jie was not at home.So Yin Zhaodi searched around the house until early morning, but no trace of the suspicious person or Yueyue was found.In the early morning, Yin Jie came back, and after finding nothing with Yin Zhaodi, he went to the police station to call the police.

The police station also investigated Yin Jie's whereabouts that night. At first he said he was playing mahjong, but because he couldn't state his poker players, he changed his words and said that he was on duty in the town. However, the police found that he was not on duty, so he He changed his mouth and said that he went to prostitution.Because Yin Jie stated that he was a prostitute he met by chance on the side of the road, the police did not find out the prostitute Yin Jie confessed to.

The police also investigated the neighbors around Yin's house. Some neighbors did hear a baby crying late at night, and the duration was relatively long, but hearing the baby crying was not suspicious, so no one got up at night to see what happened. .Others, because it was early in the morning, no neighbors went out, and no suspicious people were seen.

Yueyue didn't see anyone alive or dead body, so the case dragged on.

Three days later, on August 8, the police station in the jurisdiction received another report. The family surnamed Zhou claimed that the 20-day-old baby girl had been illegally violated, and asked the police to go to the township health center to file a case for investigation.

According to Zhou's family, their family just held a banquet to celebrate the baby girl's [-]th day at noon. The baby girl's parents Zhou Cai and Ruan Guihua drank a lot of wine, so they put the baby girl to sleep and both fell asleep.Due to the fatigue of caring for the baby and the effect of alcohol, the two slept until late in the evening before waking up. They hurried to see the baby girl, but found that the baby girl was still sleeping.After all, the baby's sleep was irregular. Although they were not woken up by the baby girl's crying all afternoon, they didn't think much about it and started preparing dinner.

Unexpectedly, the baby girl slept until more than eight o'clock in the evening, and the baby started crying as soon as she woke up.According to Ruan Guihua's experience, this is definitely not normal crying, but the kind of heart-piercing crying. The baby even showed signs of purple lips and difficulty breathing because of the crying.Ruan Guihua, who didn't know why, quickly lifted off the baby's clothes to check what was wrong with the baby, and found two red spots oozing blood on the baby's side chest.

Shocked, Zhou Cai and Ruan Guihua hurriedly sent the child to the township hospital for examination.This is also the first time the doctor has seen this situation. The contact with the red spot on the chest will immediately stimulate the baby to cry loudly.In desperation, the doctor ordered a chest X-ray of the child.Although X-rays are more harmful to babies, it is not a solution if the cause cannot be found out, and Zhou's parents can only agree with tears.

Unexpectedly, after the X-rays were taken, it surprised everyone even more.It turned out that there were actually two thin needles in the baby's chest cavity, and the red spot on the skin of the chest should be the entrance for the needles to enter the body.Although the baby had a pneumothorax in the right lung and showed signs of dyspnea, fortunately, the needle did not damage the large blood vessels and the heart.In order not to change the position of the needle during the turbulent journey and harm his life, the township health center urgently contacted the thoracic surgeon from the city hospital, who used thoracoscopic surgery to extract the foreign body from the baby.

Fortunately, the operation was successful and the baby's life was saved.Only then did the parents realize how horrible the incident was, so they quickly called the police.

Now that it is confirmed that the baby has been sleeping in the cradle, it is impossible to leave sewing needles in the cradle, and the needles taken out of the baby's body are not ordinary sewing needles, so this is basically a case of deliberately injuring the baby.After the police figured out the cause and effect, their first thought was why the baby had been sleeping and not crying, so they took the baby's blood and sent it for examination.A few hours later, blood tests showed that the baby had been given sleeping pills.

The police station then handed over the case to the criminal police team for investigation.

A task force with the criminal police team as the main force and the police station as the supplement was established immediately. The task force first hoped that the criminal technical department could extract relevant physical evidence at the scene to prove the crime, but the windows, doors, ground and cradle at the scene were all very poor. , unable to extract valuable clues, it is even hard to say whether someone sneaked into the room.Therefore, the task force first reviewed the Zhou couple.Although there is no good evidence to confirm or rule out that Zhou and his wife committed the crime themselves, it is clear that they have insufficient motives, and the investigator in charge of the interrogation also intuitively denied the possibility of their committing the crime.

As a result, the criminal police team turned the scope of investigation to those who had social conflicts with the Zhou couple.But, what kind of hatred did he do to the baby so cruelly?The task force was also puzzled for a while.After all, people live in a society, and trivial conflicts are nothing more than trivial conflicts, and a lot of them can be pulled out.Because of the lack of characterization of the depth of the contradiction, the special case team couldn't tell who to focus on investigating for a while.

Another line, the task force is also working on these two needles and sleeping pills.After component identification, it was determined that the two needles were silver capillary needles. It is said that these are the thin silver needles often used in traditional Chinese medicine, but the needle handle has been removed.Therefore, the special task force turned their targets to people in the town who might have practiced Chinese medicine, but they found nothing.In addition, the identification of the drug in the baby's body showed that there was definitely a small amount of barbiturate, a common tranquilizer that can be easily bought in the town, so the investigation of the drug buyers is still a needle in a haystack.

Some police officers from the special case team also proposed to obtain the surrounding surveillance, but the police handling the case walked around the scene for several kilometers. Except for a few traffic camera probes on the main road, there were no camera probes in the villages and towns at all, and they could not be locked at all. Images of the surrounding area.

The investigation came to a dead end, but the newly born baby was injured but the case could not be solved. Zhou and his wife couldn't understand and accept it, and they had to go to the police station almost every day to lose their temper and vent their anger.The police station knew it was wrong, and there was nothing they could do.

At this time, a policeman from the police station asked whether the baby girl who disappeared from Yin's family a few days ago might also be murdered in this way.However, apart from the fact that the target groups of violations are the same, the two cases have no basis for connection.Moreover, the Yin family's baby girl has not yet been found. The baby girl's mother, Meng Jiaojiao, even gave up her job in the city and shed tears at home every day, hoping that the baby would be stolen by traffickers and that she would be found alive. possible.

The task force has been working tirelessly, but there is no basis for screening, and there has been no breakthrough in the investigation of the case.Ten days passed in this way, and the morning of September 9st was the day when primary and secondary schools started.Unexpectedly, early in the morning, a case that shocked the whole town, even the whole city, came out.

A primary school girl arrives at school early because her parents go to work early.At about 06:30 in the morning, when the girl walked to the school gate, she found a foreign object outside the security room.When I got closer, I was almost scared to death. It turned out to be a baby girl sitting on the ground.Judging from the black lips, the baby girl had been dead for a long time.

The girl's scream woke up the security guard in the security room. The security guard hurriedly got up to check, but was also shocked severely.This is a one-year-old baby girl with disheveled hair sitting against the wall of the security room, with her head down.The security man took courage and touched the baby girl, who was cold and stiff.

After dialing 110, the security uncle quickly transferred the surveillance at the school gate.It's a pity that even if a township primary school is equipped with monitoring, it is the worst quality monitoring.Under the shroud of night, only a black figure could be seen coming to the gate of the school at 03:30 in the morning with a large bag of things in his arms. After a brief stay in the corner of the security room at the gate, he left.Reluctantly, the suspect's figure and gait could not be distinguished at all, and only one time of committing the crime could be determined.

For such a big event, the news spread like wildfire.When the police arrived at the scene, a large crowd of onlookers had densely surrounded the scene.Although the school temporarily decided to suspend classes that day, it still failed to evacuate the onlookers.More and more people gathered, and soon, a couple surnamed Zhuang also rushed to the scene. They claimed that when they woke up, they found that the child sleeping in the cradle on the side of the big bed was gone.The couple surnamed Zhuang just went out to search when they heard a neighbor saying that there was a dead baby girl at the gate of the elementary school, so they hurried over.Apparently, this baby girl was the child of Zhuang and his wife. The couple rushed into the cordon, threw themselves next to the corpse, and cried.

The police from the police station quickly called the criminal police team. This was different from the previous missing cases and the silver needle case. The shadow of surveillance was enough to prove everything.Although the appearance of the baby girl does not show any trauma, it is clearly a criminal case.

The technical police conducted a survey around the scene, but the traces of the scene had already been destroyed by the onlookers.Amidst the din of people, there was a sudden call, and the crowd began to move westward.When the policemen were confused, the police station and criminal police team received 110 orders at the same time.

In a pond three kilometers west of the township primary school, a dead body floated up.The corpse was a baby girl, less than one year old, judging by her clothes, it was the baby girl that the Yin family disappeared more than ten days ago.The corpse has been highly corrupted into dark green, swollen to the size of a giant, the scene is tragic, and the stench is suffocating.

For a town with a population of just over 4, there have been many cases of baby girl abuse these days, and naturally there have been many rumors, some of which are even far-fetched, and have something to do with some kind of sacrificial ceremony.

The police at the police station are also unwilling to hook these cases, after all, serial cases are much more troublesome than single occasional cases.However, soon, the conclusion of the forensic doctor dashed the hopes of the police.

The baby girl surnamed Zhuang was indeed unharmed, but the poison inspection department quickly found barbiturates in her brain, which was consistent with the drug ingredients in the baby girl surnamed Zhou.Apparently, they all lost the ability to cry and resist due to the effects of sleeping and sedative drugs.At the same time, after the forensic doctor performed a craniotomy on the baby surnamed Zhuang, she finally found the cause of her death: a thin silver needle was inserted from the fontanel[20] on the top of the baby’s head, and directly pierced the medulla oblongata[21].This time, the baby's respiratory and circulatory centers were directly damaged, resulting in death.Even the means of injury are the same. Needless to say, the two cases can be merged.

However, the baby girl surnamed Yin was a little different.Although the baby girl was definitely killed by external force, she was not thrown into the pond and drowned, but was thrown into the pond after being mechanically asphyxiated to death.Because there were no obvious pinching marks on her neck, the forensic doctor tended to suffocate her to death by covering her mouth and nose.However, the poison test department's poison test on the baby girl's liver ruled out that she had been affected by sleeping and sedative drugs. Nie Zhixuan led forensic colleagues to go through a detailed autopsy and found no silver needles in the baby girl's body.In order to be sure, Nie Zhixuan even conducted an all-round X-ray scan on the corpse of the corrupted baby girl to confirm that there were no silver needles in her body similar to those of the girls surnamed Zhou and Zhuang.But Nie Zhixuan, who did not give up, still found something strange on the corpse: there seemed to be several small holes in the baby girl's back and limbs.Although the corpse is highly decomposed and its properties cannot be determined, no matter how decomposed the corpse is, it is difficult to cause these strange round holes in the dermis or even the subcutaneous tissue.Combined with the two previous cases, Nie Zhixuan decisively determined that these round holes were caused by those weird silver needles.Before the baby died, it was tortured by criminals crazily. This is a tragic case of serial baby abuse.

After the forensic department led by Nie Zhixuan reported the autopsy situation to the task force, the task force made a decisive decision and combined the three cases for investigation.

The three cases resulted in two deaths and one injury of three babies. Not to mention it was an anecdote in this town where there were almost no criminal cases, it even caused a sensation in the whole city and even the whole province.For a period of time, the whole town was panicked, and the grass and trees were full of soldiers.Especially for families with babies, they have changed from the previous state of not closing their doors at night. In the hot summer, they must also lock the doors and windows, and never let the baby sleep in the cradle alone. child in arms.Even when a child was crying, the parents hurriedly looked for needle holes on the baby. If the crying did not stop for a while, the parents took the child to the health center and asked the doctor to take an X-ray for the child.

The case has caused extensive social impact, and the pressure on the public security organs is also enormous.However, the scene was destroyed by the onlookers, and no valuable traces and evidences could be found. As a result, the clues to solve the case, the basis and evidence for identifying criminals were lost from the source, and the investigation work fell into a desperate situation for a while.

Provincial departments and municipal bureaus formed an expert group to conduct research on this case.

The initial hope lies in the on-site investigation of the victim's home.Although more than ten days have passed since the incidents of the Yin family and the Zhou family, the on-site investigators of the task force still conducted a detailed inspection of the doors and windows of the two houses. At the same time, they also reviewed the photos and videos taken during the initial inspection.

The two houses are simple townhouses with complex entrances and exits.However, according to the two families, when they slept, they closed the door.Because it is a hot summer, in order to save air-conditioning electricity bills, they turn on the electric fans and open the windows to sleep. Then, the only way for criminals to enter the scene is through the windows.However, after investigation, there are no usable traces on the windows, window cabinets and window sills.After re-inspection, the technicians believed that it was not only because of the bad carrier, because even if the carrier was not good, there would be traces of scratching and climbing, but these traces were not found at the two sites.In other words, there is no way to judge the entrance and exit of criminals.

Where did the criminals enter the scene? It was also rumored by the masses that they were miraculous for a while, and even rumors of monsters, cannibals, and aliens came out.

Another group of surveyors, led by Nie Zhixuan, surveyed the house of the baby girl surnamed Zhuang and the route of dumping the body.Similarly, the only possible entrance and exit to the house of the baby girl surnamed Zhuang is the window, but there is no suspicious trace on the window.Nie Zhixuan also inspected the gate and wall of the dealer. The lock on the gate was normal, and there was no sign of prying and pressing, and there was no sign of climbing on the wall.The entrance and exit of criminals once again appeared in an unanalyzable situation.

Abandoning the search for the dealer's physical evidence, Nie Zhixuan led his team to walk several times along various roads from the dealer's house to the primary school site.Because it is in an ordinary town, as long as you are familiar with the town, you can easily avoid all surveillance, so the road of surveillance and investigation will not work.Fortunately, Nie Zhixuan, who was careful, remembered that the rigor state of the baby's corpse was curled up, which meant that after the baby died, it should be in a curled up position while the body was being transported.Regardless of whether it was held horizontally, carried on the back or carried on the shoulders, the corpse should not be curled up, so Nie Zhixuan believed that the baby girl should be wrapped in some kind of wrapping during transportation.Therefore, during the search along the way, Nie Zhixuan was determined to find this parcel.

The hard work paid off, and Nie Zhixuan really found this package.On several routes, Nie Zhixuan almost rummaged through every trash can.Colleagues didn't know his intentions, and thought that this guy is a prosthetic, so isn't he afraid of getting dirty?However, when Nie Zhixuan pulled out a yellow cloth from a trash can, everyone finally realized his intentions.

It was a piece of cloth of unknown purpose, with a few holes in it from cigarette burns.After many people's identification, the owner of this piece of cloth has not been found out.Nie Zhixuan sent the cloth back to the Physical Evidence Appraisal Center of the Municipal Bureau for physical evidence extraction. Sure enough, he found bloodstains of the baby girl surnamed Zhuang on the cloth.Unfortunately, the physical evidence department was unable to find the DNA of the second person from the cloth, and the only physical evidence that could directly point to the criminals was gone.However, the physical evidence department extracted some fat components from the cloth, including animal oil components and vegetable oil components, so it was analyzed that this may be a tablecloth.

The road of physical evidence has come to a dead end again, and the task force can only sit down again to study the motives of the criminals.

In the case of child abuse, there are several motives for committing the crime: the most common one is that parents hurt or kill their own children. However, these three cases came from three different families, so they were excluded.The second is the cases of sexual assault and molestation of infants and young children. However, the victims' sexual organs in the three cases did not show any signs of damage, so they are not very similar.Furthermore, it is the abduction and trafficking of babies, which is obviously not the case in these three cases.There is also a possibility that there is a grudge against the parents of the three babies. This is an act of revenge. However, after a month-long investigation by the police and more than a thousand interviewees, it is determined that there is no connection between the three families. There is no common contradiction, and in this town of tens of thousands of people, there are many families with babies. The three victim families should have been randomly selected, so this motive was immediately ruled out.In the end, mental illness hurt people. The police spent another month investigating all the mentally ill or those with symptoms of mental illness in the town. Unfortunately, there was no basis for screening, and they returned without success.

As a result, the case investigation work seems to have lost its direction again, and other ways have to be considered.

The police also wanted to investigate the source of the silver needles, but after experts identified them, these silver needles were very common fine acupuncture needles used in traditional Chinese medicine, with the handles removed. It is really easy to obtain such silver needles .But the police seized on this life-saving straw and still conducted a round of in-depth investigations.A survey was conducted on all the people in the town who are related to Chinese medicine, as well as those who bought fine acupuncture needles online and went to the vicinity of the town. As a result, many people who had silver needles at home secretly hid them, falsely claiming that they did not have them, Save yourself the trouble of being questioned by the police.

The video team is also a clever woman who can't cook without rice. There are very few traffic surveillance camera probes in the town, and civilian camera surveillance probes are even rarer.Even obtaining images from limited camera probes is worthless for various reasons.

In the end, the task force returned the investigation and handling goals to two directions.

One is on people who may have mental problems or psychological problems; the other is the theory of relatives committing crimes proposed by Nie Zhixuan.According to the "Victimology" researched and summarized by the Ministry of Public Security, most of the violations of infants and young children are committed by their parents or immediate relatives.Nie Zhixuan proposed a possible direction, if someone becomes addicted after attacking his own child, he looks for other targets to commit crimes.Then, according to the timeline, the earliest incident should be the case of the Yin family, and it happened that Yin Jie could not clearly explain his whereabouts that night.

Some policemen believed that Yin Jie was indeed suspicious, and he lied to the police continuously after major incidents happened at home.Although it may be because he cannot tell the truth because he went out to whoring, after all, his last statement of "going to whoring" has not been confirmed.Then, it can be considered that he has the time to commit the crime.

Now that there are new clues and suspects, the police place their hopes on it as if placing a bet.

Fortunately, a few months have not passed yet, and everyone still has deep memories of what happened a few months ago.After investigation, Yin Jie's suspicion began to rise gradually.Three days after the baby girl of the Yin family disappeared, that is, the afternoon when the baby girl of the Zhou family was raped, Yin Jie pushed Pai Gow at his cousin's house at the east entrance of the village.Although there are alibi made by his cousin and several Fa Xiao, the police believe that the possibility of perjury by these people who have obvious interests in Yin Jie cannot be ruled out.Moreover, three days after his little daughter disappeared, when his wife rushed back from other places to look for the baby girl, he was gambling, which is incomprehensible.

Ten days later, that is, the night when the Zhuang family's baby girl was raped, it happened that Yin Jie was on duty.However, the factory security guard is always on duty alone, patrolling the site every two hours and signing in at a specific place.Although Yin Jie signed in at every check-in point that night, the time when the criminals appeared in the school surveillance was 03:30 in the morning, and this time happened to be the gap between the two check-in times between [-]:[-] and [-]:[-] .If Yin Jie had acted faster, he could have used this gap to sneak out of the factory and complete the entire crime process.

The biggest problem is that Yin Jie has practiced martial arts before. As for whether he can use some abnormal method to enter the house, at least he has a greater possibility than others.Moreover, Yin Jie's smoking also has the conditions to leave smoke marks on the tablecloth.

Looking at it this way, the possibility that Nie Zhixuan analyzed "after his own family committed crimes, he found that this method can stimulate his pleasure, and then continued to commit crimes" exists.Yin Jie's suspicion thus surfaced.

Due to the lack of valid evidence to apply for a search warrant, the police sent a group of investigators to conduct a secret investigation at Yin Jie's home under the pretext of an investigation visit.The focus of the survey was first to find similar silver needles, and second to find out whether Yin Jie had any tablecloths in his home, or whether he had replaced them with new ones.

Unfortunately, this secret survey failed.The investigators even used metal detectors, but they couldn't find the same silver needle in Yin Jie's house.Moreover, the tablecloth in Yin Jie's house is very old, obviously the bedding on the table has not been changed for a long time.Neither of these two conditions that could be used as indirect evidence was met, and the task force was not sure whether Yin Jie was a suspect.

Time flies, so soon in the middle of this year, Nie Zhixuan was transferred to the Night Watch organization and started a new job.But when he was working, he still asked about the progress of the "silver needle baby girl" case at any time.According to Nie Zhixuan's understanding, the police finally lost all options and had to make a desperate effort to catch Yin Jie back.Although he encountered fierce resistance from Yin Jie when he was arrested, Yin Jie has always had a good attitude after being arrested.Although he has a good attitude, he firmly denies committing the crime.Yin Jie was released and returned home after days of detention for mob gambling.

The case eventually fell into the dark.

Fortunately, in the past few months, there have been no more cases of baby girls being raped in the town.On the one hand, it may be that the parents' awareness of prevention has increased, and on the other hand, it may be that the criminals have no chance to commit crimes again due to the continued high pressure from the police.

After the Night Watchers successfully cracked the high-speed haunting case, Nie Zhixuan formally asked the Night Watchers to make a breakthrough in the case.

Because any unsolved murder case will be a knot in the heart of a criminal policeman.This wide-ranging case is a deadlock in Nie Zhixuan's heart.

Nie Zhixuan introduced the whole situation of the case with his unique steady and low voice, because it involved a lot of scene and autopsy photos, Tang Dangdang almost listened with his head down.

Not only Tang Dangdang couldn't bear the impact of the pictures, but even Ling Mo trembled when he saw the baby girl who was highly corrupted and looked like a giant.Seeing the baby being brutally abused touched the softest part of the young Night's Watch member's heart.

"Now the Criminal Investigation Bureau of the Ministry of Foreign Affairs has handed over this case to us. We will solve the case within a time limit and restore the peace of the local people." Fu Yuanman said, "Nie Zhixuan, what do you think is the biggest difficulty in this case?"

"All homicide detection work starts with on-site investigation and reconstruction. The basis for us to narrow the scope and extract clues and evidence is based on the reconstruction of the scene, and the beginning of the reconstruction of the scene is the entrance and exit analysis." Nie Zhixuan said , "Now we don't even know the entrance and exit of the criminals, so we have no way to start the investigation. The murderer can't fly in, right?"

"Could it be that there is something wrong with your investigation?" Xiao Lang asked.

"We have re-examined the scene of the three lost babies several times." Nie Zhixuan said, "I'm sure that the door of the house I entered was closed, and it was impossible for outsiders to enter; Someone might have climbed through the window. Other than that, there's no other possibility."

"That is to say, people can complete the crime process without entering the scene." Xiao Lang pondered.

"Inspired by the previous case, since we can't use science to explain the entrance and exit, why don't we explain it for now." Ling Mo said, "Change the way of thinking. Changing the way of thinking is the only way to solve the dead end."

"What idea?" Xiao Lang asked.

Fu Yuanman said: "Ling Mo, you are a mind reader, why don't you analyze the psychological characteristics of the criminals involved in this serial child abuse case."

Ling Mo lowered his head and rubbed his chin, as if he didn't hear Fu Yuanman's words.

Xiao Lang poked Ling Mo with his elbow, and said, "Grandpa is asking you something, I want you to analyze the motive of committing the crime. I think it's just a pervert, a man, a middle-aged greasy man."

"Oh? What's the basis?" Fu Yuanman looked at Xiao Lang with interest.

Xiao Lang scratched his head, he took it for granted on a whim, there is no basis for it.

"It's the same reason. In addition to reconstructing the scene, we are always used to solving cases from the motive." Ling Mo said indifferently, "But why do we still have to think habitually in a case where the motive cannot be determined?"

"You mean," Fu Yuanman said, "the other way around?"

Ling Mo nodded, and said: "The starting point for reconstruction and the motive for committing crimes cannot be found. These are the unusual features of this case. For cases with abnormal phenomena, we have to keep changing our thinking until there is a way to go." OK. What if we put aside on-site reconstruction and motive analysis, avoid preconceived ideas, and just analyze based on the evidence and phenomena at the scene?"

"Do you have any high opinion?" Xiao Lang deliberately emphasized the word "high opinion".

"Not yet." Ling Mo said, "But I think the starting point of these three cases is the only physical evidence we have obtained so far - the tablecloth, the three victims, and the behavior of the last case. From these three elements Go ahead."

"How to proceed?" Xiao Lang asked.

"Are there no other additional injuries on the three victims?" Ling Mo turned to Nie Zhixuan.

Nie Zhixuan tapped on the keyboard with his left hand and his flexible mechanical right hand. After a while, the photos of the three victims were displayed side by side on the large LED screen behind him.Tang Dangdang bit her lips silently.

"The Yin family's baby girl has additional damage." Nie Zhixuan zoomed in on the decayed baby girl's mouth, and said, "There are damages to the root of the gums and the tip of the tongue, which should be the damage left when covering the mouth and nose. And , this child also died of mechanical asphyxiation caused by pressing her mouth and nose. Other than that, the other baby girls had no additional injuries.”

"That is to say, the methods are inconsistent." Xiao Lang said.

Ling Mo said in a calm tone, "No, it's an upgrade."

"No matter how you look at it, it looks like this Yin Jie." Xiao Lang said.

Nie Zhixuan recognized it very much, nodded vigorously, and said, "It's helpless, there is no evidence, and his mouth is also very hard."

"The physical evidence you mentioned, the shroud, is there anything else to dig up?" Fu Yuanman said.

"Take me to have a look." Ling Mo turned to Nie Zhixuan and said, "Where is the physical evidence?"

"In the evidence room of the Municipal Bureau." Nie Zhixuan raised his metal right arm, pointed at Ling Mo and himself, and said, "Just the two of us?"

Ling Mo thought about it again, he couldn't afford to deal with the hair on his clothes in the morning, he was blind, and he couldn't catch a glance at Xiao Lang, so Ling Mo smiled and said, "No, there is brother Xiao Lang."

"Hehehe, let me tell you that when you need me, you are brother Xiao Lang, brother Xiao Lang, and you run away quickly when you don't need me." Xiao Lang protested, waving his fists.

Ling Mo put his arms around Xiao Lang's shoulders and said, "Let's go, there are so many things to talk about."

Ling Mo and Xiao Lang stood side by side at the door of the physical evidence room, watching Nie Zhixuan quickly find the tablecloth among the piles of physical evidence.If you don't know Nie Zhixuan very well, you really can't see that he is a disabled person with artificial limbs.

Nie Zhixuan carefully took out the tablecloth from the evidence bag to confirm the serial number.Because it's a prosthetic, you don't even have to wear gloves.After confirming the number, Nie Zhixuan carefully put the tablecloth back into the evidence bag, and walked out of the evidence room with the evidence bag in hand.

"Although it is physical evidence that has been tested, we must be so careful." Nie Zhixuan said, "Otherwise, many physical evidence that we have not found may be lost in the process of transportation and transfer."

"I want to know, how did you find and inspect the suspicious spots?" Ling Mo asked.

"Well, for the bloodstains, I used luminol." Nie Zhixuan said, "After all, looking for bloodstains on such a large and unclean tablecloth is no different from finding a needle in a haystack."

"So you just found a drop of blood?"

"Yes, there is a fluorescent reaction." Nie Zhixuan said, "And it does not affect the DNA test of the blood, which is the best shortcut. However, it is not a drop of blood, but a few bloodstains."

"Isn't there an open wound on the baby's body the size of a small needle eye?" Xiao Lang asked.

Nie Zhixuan nodded.

"If it is a simple walk, the tablecloth should stick to the baby's body, and there should be a little blood on it." Ling Mo said, "Only the violent bumps during the large-scale movement will change the position between the baby's head and the tablecloth, forming a New bleeding marks. Xiao Lang, right?"

"Ah? Why are you asking me?" Xiao Lang was stunned for a moment.

"Aren't you good at sports?" Ling Mo said with a smile, "I've arrived in the laboratory, now I really want to ask you."

Three people entered the laboratory. The laboratory was built according to the standard of a darkroom for the convenience of using multi-band light sources [23].Nie Zhixuan first urged the two to put on their gloves, and then carefully spread the tablecloth on the laboratory table.

It was a piece of silver-gray woven cloth about one meter long and one meter wide. It looked like a rectangle or a square, and there were many stains on it.

Nie Zhixuan turned off the overhead light in the laboratory, and the entire laboratory instantly entered a state of pitch darkness, where he could not see his fingers.Nie Zhixuan turned on the multi-band light source and illuminated the tablecloth with light from various bands.

"Where are the vegetable oils and animal oils you mentioned earlier extracted?" Ling Mo asked.

Nie Zhixuan pointed to the tablecloth vaguely, and said, "I feel that this cloth is simply dirty. If you want to say where there are spots, I haven't found them."

"You mean, the oil stain is evenly adhered to the cloth?" Ling Mo asked.

"Let's put it this way." Nie Zhixuan said, "We just randomly found a few spots on the cloth, and we detected the ingredients of vegetable oil and animal oil. Oh, only this side has oil, and the other side has no oil. So, we analyzed This side is laid face up on the table. And, look at the smoke holes, this side is also larger and has traces of smoke, while the back is smaller and has no traces of smoke.”

"Xiao Lang, can you see anything?" Ling Mo said.

"What are you looking at in such pitch darkness?" Xiao Lang turned on the light while talking, and leaned over the experiment table to watch.

"We have seen all of them. Except for what we found, there is no doubt, or there is no basis for identifying criminals." Nie Zhixuan said, "We randomly extracted more than 100 points and wiped them, and we did not find anyone else's. DNA, that's pretty much covering the entire tablecloth, unless we're unlucky."

"It means that this piece of cloth is rarely touched by anyone," Ling Mo said.

Before Ling Mo finished speaking, Xiao Lang straightened up and said, "What tablecloth, this is a curtain."

"Curtains?" Nie Zhixuan exclaimed.

Ling Mo's shoulders also moved.

"How could it be a curtain?" Nie Zhixuan said, "There are no rings or pull hooks on one side, and there are so many oil stains. I'm talking about oil stains, not dust. And, have you ever seen curtains that are so small? Usually A rectangle two meters long? This is almost a square."

"You can't see it?" Xiao Lang gestured on one side of the fabric.

Ling Mo and Nie Zhixuan shook their heads at the same time.

"There are traces of rust here, section by section." Xiao Lang said, "Indeed, it has no rings, hooks or anything like that, but the principle of this curtain is the iron clip hanging from the curtain track, clamping the cloth section by section. One side becomes a curtain."

"Rust?" Nie Zhixuan was still in doubt.

"I believe in Xiao Lang's judgment, and based on the traces drawn by Xiao Lang, physical evidence can also be extracted to determine the composition of the rust." Ling Mo said, "The components of the oil stains you made from materials before were not extracted from the curtain. Edge?"

"Of course, the material is collected from the center." Nie Zhixuan scratched his head with his prosthetic limb, and said, "Besides, I thought it was a tablecloth at first, so it's impossible to get evidence from the edge. It's meaningless."

"The oil doesn't stick to it in one piece, but it's uniform and dense." Ling Mo said, "This means that it's the kitchen curtains, because there is a lot of oily smoke in the kitchen, which can form an even and dense oil adhesion, and the oil contains both vegetable oil and oil. There is animal oil. And the windows in the kitchen are usually smaller than the windows in the room, so the curtains are also smaller. As for whether it is a rectangle or a square, it depends on the shape of the window. On the curtains, the one with oil stains faces inward, and the one without oil stains faces outward. If Yin Jie If you cook at home, you may smoke while cooking and form a smoke hole."

"Right? It's just a curtain." Xiao Lang said nonchalantly.

"This may be a breakthrough." Ling Mo said.

"Ah? Right? It's the curtains, right? Look, look, if this case is solved, I'll be the first one." Xiao Lang said while patting his chest.

"We did have preconceived ideas in the early stage." Nie Zhixuan said, "However, I didn't hit you. Even if it turns out to be curtains, it may be useless."

"No way." Ling Mo said, "The reason why you don't have evidence is because you took this as a tablecloth, but the tablecloth at Yin Jie's house is in normal condition, and it's not new, so it's ruled out."

"If it's a curtain, it can be ruled out." Nie Zhixuan led the two of them to the office next door, downloaded a folder from the FTP (File Transfer Protocol) on the public security intranet, and said, "This is our investigation of Yin Jie's house." Take a look at the videos and photos from the secret search."

The video was shot by a body camera, which captured almost every corner of Yin Jie's house, including the kitchen of course.The direction of Ling Mo's analysis is good. Many rural families will install curtains in the kitchen.However, the kitchen curtains of Yin Jie's house were fluttering in the window normally. They looked old and dirty, with no signs of being replaced, and they were a circle larger than the piece of cloth they saw.Moreover, the careful Xiao Lang also found that the window rails of the kitchen windows were in the style of pulleys, not the simple clamps he mentioned earlier.

"At that time, I paid attention to wherever there might be cloth," Nie Zhixuan said, "There is no possibility of a new one. And this shroud is very dirty, and it cannot be something that was hidden by criminals."

"After all, this is the first case, and it is the most valuable one among the three cases." Ling Mo said, "It's not that I can't trust you, Brother Nie, but I think we still have to go to Yin Jie even after a year. It is necessary to take a look at home."

"That's no problem, I'll take you to talk to their family members." Nie Zhixuan said, "Ling Mo's mind-reading ability, maybe you can find something."

Ling Mo smiled and said, "We're taking Zimo with me, and I hope her sixth sense will find something."

"Do you want to bring Dangdang?" Xiao Lang looked left and right, "There is great strength in numbers."

"Dangdang can't, Dangdang has other tasks." Ling Mo said.

"Hey! Why do you arrange work for our family Dangdang? She has been tired enough recently, and she has seen so many autopsy photos." Xiao Lang waved his fist again.

Ling Mo had already finished sending text messages to Cheng Zimo at this time, and walked in front alone, saying, "Dangdang belongs to Teacher Tang's family, not yours. Also, what happened to the autopsy photos? Don't underestimate Dangdang's psychological burden." force."

After nearly two hours of bumpy trek, the jack drove to the outskirts of the town where the incident occurred, and it was already night.Ling Mo asked everyone to get off the car and walk into the village.After all, if a car as eye-catching as a Jack is driven into town, it will definitely attract more gossip.After a year of precipitation, the town has finally calmed down again, and the people here can no longer stand the toss.

Nie Zhixuan led the other three people, walked for more than three kilometers, and came to a red brick townhouse.

"This is Yin Jie's house." Nie Zhixuan turned on the flashlight of his mobile phone and said, "The second door from the left is the door of his house."

"Is that the pond where the baby was found?" Xiao Lang pointed to the east.

The other three looked in the direction of Xiao Lang's finger, it was pitch black, and there was no pond there.

"Uh, look at the direction, yes." Nie Zhixuan said awkwardly.

"He's showing his eyesight again." Ling Mo shrugged and walked straight forward.

"We are from the Public Security Bureau, or your family's case. We want to talk to you again." Nie Zhixuan walked less than 100 meters, and happened to meet a woman sitting in front of the house. Not surprisingly, this is the dead woman. The baby's mother, Meng Jiaojiao, died.

As if a switch had been pressed, Meng Jiaojiao immediately burst into tears when she heard the word Public Security Bureau.She still sat there, noncommittal.

The four of them stood awkwardly in front of the door, when a slim young girl came out, who must be Yin Zhaodi, Meng Jiaojiao's eldest daughter.She looked a little shy, but she walked to the door with her head down and said in a low voice, "Please come in, but my dad is not at home."

"It's okay, it's okay, we just take a look." Nie Zhixuan said quickly.

"Where did your father go?" Xiao Lang tried his best to pretend to be relaxed, but it still sounded like he was interrogating a prisoner.

"Ah, it's his turn to be on duty." Yin Zhaodi said tremblingly like a frightened little rabbit.

Ling Mo glared at Xiao Lang, did not speak, and walked around the house.Yin Zhaodi stood in the living room with his head down, not looking at them, as if he was thinking about something.

Ling Mo walked to a side bedroom, which was obviously Yin Zhaodi's own private room.It is said that this is where the criminals broke into the house through the window and stole the baby at the time of the incident.But at this time, there is no shadow of the cradle here.

"Excuse me, girl, where is the child's cradle?" Ling Mo asked cautiously.

"Mom and Dad burned all my little sister's things, including the cradle, for fear that they would miss her when they saw it," said Yin Zhaodi.

"What about this one?" Ling Mo pointed to a small feeding bottle on the bedside table.

"Oh, I left this secretly, you can take a look when you miss your little sister." Yin Zhaodi said with a sad face, "I have brought her with me since I was a child."

Cheng Zimo couldn't bear it, took the little girl's hand, walked outside the house, and chatted with the little girl.

Ling Mo nodded if he realized something, and walked into the kitchen again.Sure enough, there was a curtain hanging over the kitchen window.But judging from the size, texture, and pattern of the window rails, it has nothing to do with the shroud. Moreover, the curtain is already dirty, and there is obviously no sign of new replacement.

Ling Mo opened the curtains, looked up, down, left, and right at various positions of the window frame, his eyes suddenly lit up.

"Xiao Lang, Xiao Lang, come and let me ask you a question." Ling Mo shouted from the kitchen.

Xiao Lang ran into the kitchen in a hurry, and said in a low voice, "What is it, what do you see?"

Ling Mo raised the curtain with one hand, pointed to the top of the window frame with the other, and said, "Look for yourself."

Xiao Lang raised his head, looked at it, and almost cried out in surprise, but fortunately Ling Mo had already made a "shh" gesture as expected.Xiao Lang looked at Ling Mo asking for advice, Ling Mo nodded with a calm smile.

"What should I do?" Xiao Lang said.

"Go back." Ling Mo said concisely.

Walking to the door of the house, Ling Mo signaled Nie Zhixuan and Cheng Zimo to go first, while he and Xiao Lang stayed behind, comforting Meng Jiaojiao a few words.

"When will you give me justice?" Meng Jiaojiao asked in tears.

"Three days." Xiao Lang raised three fingers.

Meng Jiaojiao looked up at him hopefully.

Ling Mo also stared at Xiao Lang helplessly.

"Ah? Isn't it right?" Xiao Lang noticed Ling Mo's eyes, retracted two fingers, and said, "Then, one... one day?"

After Ling Mo and Meng Jiaojiao said goodbye briefly, they took Xiao Lang's shoulders and pulled him back to the path.

"Am I wrong?" Xiao Lang asked.

"It doesn't matter." Ling Mo pointed to the front of the path and said, "These two people are running so fast? They are gone."

Xiao Lang looked ahead and said, "It's so dark that I can't even see them. What can you see? But I can still see the road under my feet clearly. Hold me and don't fall into the pond. I Wasn't that right?"

Ling Mo smiled and walked along the path without saying a word.

"It was Yin Jie who committed the crime, that's right." Cheng Zimo said in the car returning.

"Do you have a sixth sense?" Xiao Lang never believed in Cheng Zimo's so-called "sixth sense".

"Yeah, I chatted with that girl, and I obviously felt that she was hesitant to speak." Cheng Zimo tried to imitate her feeling as much as possible, and said, "It's the kind of person who wants to tell us something, but dare not The kind you said."

"Maybe she wants to tell you that she likes you." Xiao Lang laughed.

"Get lost." Cheng Zimo said, "Later, I held her hand and talked, and as I talked, I discovered something unusual."

"What's abnormal?" Xiao Lang sat up straight.

"Because the sleeves retracted as soon as they held hands, exposing a section of her wrist." Cheng Zimo described, "She is so young and has very good skin."

"Cut!" Xiao Lang slumped back on the seat again, "I thought it was something I discovered. Are you going to start writing novels? A wrist like a lotus root..."

"Don't interrupt." Cheng Zimo gave Xiao Lang a blank look, and said, "There are two spot-like scars on her wrist. It looks like the scar left after being poked by a needle."

"Can needles leave scars?" Xiao Lang turned his head and asked Nie Zhixuan.

Nie Zhixuan nodded and said, "If you have a scar constitution, as long as the damage spreads to the dermis, keloids may form."

"And it looks like those two scars have been around for many years." Cheng Zimo said, "She is only 16 years old, so it couldn't have been caused by self-harm a few years ago, right?"

"You mean, Yin Jie has a history of abusing Yin Zhaodi since she was a child?" Xiao Lang said.

The jack jerked a bit, probably avoiding a pothole in the road.Ling Mo in the driver's seat was driving intently throughout the journey without saying a single word.

Back at the organization, Fu Yuanman was still waiting in the big meeting room.

"Grandpa, it was Yin Jie who committed the crime." Xiao Lang shouted before entering the meeting room.

"Call the team leader." Fu Yuanman's tone was very serious, but the way he looked at his grandson couldn't be serious.

"Ling Mo found several small holes arranged in parallel on the window frame of Yin Jie's kitchen window, indicating that there was another curtain track before." Xiao Lang said, "If this is true, then Yin Jie must have taken He took the outer layer of two curtains from his kitchen to wrap the body. He then went home and removed the curtain track of the outer curtain."

"Two layers of curtains?" Fu Yuanman asked.

"Well, I can confirm that it was an old curtain track that was removed." Ling Mo added, "I carefully observed the structure of their house. There is a street lamp outside the kitchen window. It is broken now, but it must have been good before. This street lamp The direction of the light is right through the window of Yin’s kitchen, and directly shines into the master bedroom opposite the kitchen. It’s okay if the door of the master bedroom is closed, but if you want to open the door to ventilate in summer, you will be disturbed by street lights. My analysis, the piece of shroud The curtains are the earliest curtains, but because they are silver-gray and have a relatively high light transmittance, they added an inner curtain later. It is precisely because the shroud uses the outer curtain, while the inner curtain is normal, that it is misleading. We didn't find this important clue."

"This is a clue, not evidence." Fu Yuanman said.

"It's okay, leave this matter to me." Xiao Lang patted his chest and said, "Ling Mo said that hiding corpses and hiding important physical evidence have the same psychological origin, so they are likely to be hidden in the same place. I read Around Yin Jie's house, there is only one pond that is suitable for hiding important physical evidence. Although a year has passed, I believe that the broken curtain track must still be at the bottom of the pond."

"Salvage the track, compare the traces of the iron clamps that Xiao Lang saw, and then compare the screw holes on the track with the screw holes on the window frame, and then you can make the same identification." Ling Mo Said, "This is no longer circumstantial evidence, it can be used as direct evidence."

"Let's act at dawn." Fu Yuanman said with a smile, "Everyone needs to rest now."

Ling Mo did not rest.

He came to the operation room of the Sky Eye team of the Night Watchers alone, Tang Dangdang was facing away from him, focusing on the pictures on the computer screen.

"How is it?" Ling Mo stood behind Tang Dangdang.

"Ah?" Tang Dangdang woke up from his own world, turned to Ling Mo and said, "Indeed, there are traffic camera probes on the east and west sides of the primary school site, and the images recorded by the surveillance camera probes at the school gate are basically It is possible to restore the images of all the onlookers who came to the scene that day. However, it is not very clear."

"It's okay if you don't know. If you have a general outline, you can basically be sure." Ling Mo said, "How many people?"

"Four to five hundred." Tang Dangdang pointed to the densely packed small icons on the computer screen.

"Yeah." Ling Mo leaned over to look at the screen, touching Tang Dangdang with his shoulder.

It may be that there is still estrangement and vigilance towards Ling Mo in his heart, or it may be that the two of them being alone reminded Tang Dangdang of the past. Tang Dangdang shook slightly, avoided Ling Mo's contact, and walked away from Ling Mo with his head bowed: " Look, I'm leaving."

Ling Mo didn't take it seriously, sat down on Tang Dangdang's seat, and opened a row of photos at the same time, looking for a familiar face among the faces in the photos, as if expecting something.

Early the next morning, after Xiao Lang laughed at Ling Mo's dark circles, he climbed up the jack first.Wan Jin led several special police and firefighting vehicles and drove directly into the village.More than a dozen firefighters got on and off two fire trucks to coffer the water inlet of the pond [24], and began pumping water from the pond with a water pump.

However, Xiao Lang and his group went to Yin Jie's house and learned that Yin Jie was on duty last night, but he has not returned yet, and his whereabouts are unknown.

"Could it be that we came here last night to scare the snake away?" Xiao Lang said worriedly, "I have to find him."

"Zimo, you and Xiao Lang go together, and bring a carload of colleagues from the special police." Ling Mo said.

"Okay, I'll go and watch the salvage work." Nie Zhixuan left expectantly.

On the open space in front of Yin Jie's house, only Ling Mo was left standing alone, facing Meng Jiaojiao who was still sitting at the door crying.

"Uh, can I go in and sit down?" Ling Mo broke the awkward atmosphere and said.

The long-term psychological trauma made Meng Jiaojiao's thinking slow down, and she nodded slightly after a while.

Ling Mo seemed to have received the order, and immediately turned around and walked into the house.In the room, Yin Zhaodi was sitting in the middle of the main room, choosing vegetables on a small stool.Ling Mo walked in, she was still choosing dishes as if she hadn't seen it.As Cheng Zimo said, several keloids could be seen under her rolled up sleeves.

Ling Mo walked through the second bedroom, glanced at the feeding bottle on the bedside table, and walked straight to Yin Zhaodi.For a long time, Ling Mo didn't speak, and Brother Yin Zhao also chose dishes as if no one else was around.

"I have one last question left to solve, and it is precisely because of this abnormal phenomenon that the police have not solved the case after a year." Ling Mo said, "You look weak and weak, but why are you jumping? So capable?"

Yin Zhaodi trembled all over, but did not speak.

"The window sills of several scenes are so high that you can easily enter with a hurdle posture. This is not something ordinary people can do." Ling Mo said coldly.

"Brother, you must have made a mistake." Yin Zhaodi raised his head, and looked at Ling Mo beseechingly with his big watery eyes.

Ling Mo stared into her eyes and said, "I sympathize with you, but if you are wrong, you are wrong."

"I don't know anything." Yin Zhaodi lowered his head to choose vegetables, and the leaves swayed slightly with her trembling hands.

"These scars must have been pricked by needles." Ling Mo pointed to Yin Zhaodi's arm.

Yin Zhaodi shook, pulled down his sleeves a little, and said nothing.

"It hurts, right?" Ling Mo said.

Brother Yin Zhao lowered his head even lower.

"It doesn't mean that you are in pain, but it means that everyone else should be in pain, right?" Ling Mo said.

"I can not understand what you say."

"Then let me tell you something you can understand." Ling Mo has completely confirmed his inference through Yin Zhaodi's small actions, and he said with confidence, "Being abused since childhood cannot be a reason for your crime. I can't just because If you were abused when you were young, you will not be arrested."

"What? Yes! I was abused by that bastard Yin Jie since I was a child. Even my mother outside didn't dare to take care of me. No one cared about me, no one asked me. I was like a dog, a dog that delayed their Yin family's succession! Tears welled up from Yin Zhaodi's big eyes, "But instead of arresting Yin Jie, you came to arrest me?"

"He abused you and will be punished by law." Ling Mo said, "But he didn't kill anyone."

Brother Yin Zhao lowered his head, wiped away his tears silently, and continued to choose vegetables, saying, "You have no reason to doubt me."

"You are lucky." Ling Mo took a small bench from the side, sat beside Yin Zhaodi, and said softly, "At first, you hoped that the police would find no evidence to lock your house. But last night we came After that, we went to the kitchen, you saw it, so you know that the police have slowly found clues to physical evidence. Your dark circles indicate that you didn't sleep last night, maybe you wanted to The curtain track is salvaged and thrown away, but you know it's not going to be possible for you. The curtain track has been in the water for a year, and it must be stuck in the mud. If it weren't for a professional salvage, there would be no way to find it. So, When you were chatting with the police lady last night, you wanted to tell her the fact that you were abused, so that the police could only focus on Yin Jie. You didn’t say it directly, you deliberately exposed your scars, Let the police find out by themselves. Why did you choose this time to expose your scars? The police have been investigating for more than a year, and you have not mentioned a word. It is because you let the police give up the investigation before. When you leave, put all the responsibility on your father, Yin Jie."

"What does this have to do with curtain rails?"

"The curtain that wraps the corpse has been identified as the same as the track."

"Even if you find the track, you can only be sure that the murderer belongs to our family. I have been abused since I was a child. Is this enough to convict Yin Jie? I don't understand why you doubt me." Yin Zhaodi was surprisingly calm.

"Then I'll talk to you about the details." Ling Mo said, "The first thing that made me suspect you was the third baby case. You killed the child named Zhuang..." Ling Mo said.

"I didn't kill her!" Yin Zhaodi raised his head again, with anger in his eyes.

"Your anger has exposed your heart." Ling Mo folded his arms and looked down at Yin Zhaodi.

Tang Jun had taught him to maintain a conquering posture when chasing after a victory, which would be more conducive to breaking down the opponent's psychological defense.And this posture and eyes are the simplest gesture of conquest.

Yin Zhaodi's voice really became quieter, and he didn't dare to look directly into Ling Mo's eyes: "What's wrong with me? I didn't kill her."

"Okay, then let's change the way of expression." Ling Mo smiled slightly and said, "After the child died, the murderer could have fled in a hurry. But why did the murderer go out to get a shroud and then go back?" How about removing the body? If we simply hide the body, we will think that the murderer is prolonging the crime, but the murderer put the body in the most obvious place. This is not hiding the body, but exposing it. The murderer has Exhibitionist, because of her previous two crimes, her mentality has been upgraded, she is no longer afraid, but hopes that more people will see her 'masterpiece', and she can gain psychological satisfaction through such exposure."

"What does this have to do with me?" Yin Zhaodi said.

"Exhibitionism is a kind of mental illness." Ling Mo emphasized the word "exhibitionism". This method of stimulation may further cause Yin Zhaodi to lose control of his emotions.

"I have a mental illness, and it's not me." Yin Zhaodi's voice became louder again, which was a sign of loss of control.

"Even if the murderer has exhibitionism, she can leave with a child weighing more than ten pounds on her shoulders after killing someone, but why go home to get the curtains?" Ling Mo made a face. With an unfathomable expression, she said, "Because she can't carry her back. Someone who can't even carry a baby weighing more than ten kilograms must be abnormal. What's even more abnormal is that she actually has a strong leaping ability. In my case When I saw you for the first time, I found something suspicious. You walked normally and lightly, indicating that your lower limbs are very strong, but your hands often tremble unconsciously. This is a pharmacological muscle tremor. It is a long-term medication The sequelae left by sedative drugs. Coincidentally, the next two children were in the process of being stabilized by drugs."

"A lot of people take sleeping pills, right? As far as I know, Yin Jie often takes them too." Yin Zhaodi said.

"Indeed, this most common sleeping pill is easy to buy." Ling Mo said, "Although the purchase of medicines is limited, if you don't take the medicine for one night, you can poison several children. And, in the end The key is that you meet the characteristics of upper limb problems and lower limbs are sound."

"That doesn't mean anything."

"With this idea, I also have a goal." Ling Mo said, "Do you still remember? When you were first investigated by the police, you said that the night your little sister disappeared, you rushed to the small road to find her. , I saw a figure 300 meters away, and suspected that it was the person who stole your little sister. Unfortunately, I conducted a detection experiment last night, and my two companions walked for 3 minutes, but they were only about 100 meters away from us. You can’t see anything at all. That means you’re lying.”

"That may be because I remembered wrongly." Yin Zhaodi said.

"I also had this hope, and I didn't want a young girl to commit the crime." Ling Mo sighed. Sometimes, this kind of empathy-like language would make the other party less defensive.Ling Mo went on to say, "However, when I went back that night, I watched some pictures found by our computer experts. Generally, people with exhibitionism, the reason why she can get pleasure when her 'masterpiece' is watched by everyone, first of all She wants to be able to visit the scene in person and feel this kind of crowd. Although I am very young, I have seen many documentaries of case investigations. Almost all people who are prone to exposure will return to the scene to participate in the crowd after the crime. The face recognition pictures of the crowd watching the case of the baby girl surnamed Zhuang, unfortunately, you are one of them."

Yin Zhaodi opened his mouth, but said nothing.Ling Mo knew that Yin Zhaodi's mental state had reached a dead end.

"The curtain track will be salvaged soon, and you will be punished soon." Ling Mo said coldly.

"Those are all your guesses, and you have no evidence." Yin Zhaodi was making the last resistance.

Ling Mo stood up and took out a transparent evidence bag from his pocket as he left.After a while, Ling Mo returned to Yin Zhaodi's side, with a baby bottle in the evidence bag.

"This is your little sister's milk bottle, you keep it all the time, right?" Ling Mo asked.

Yin Zhaodi's face was a little ugly, but she was trying to suppress it, so she nodded slightly.

"It doesn't matter if you don't admit it." Ling Mo said, "Because through the inspection on the outside of the bottle, it can be found that there are only your fingerprints and DNA, and no one else will touch it."

"So what?" Yin Zhaodi said.

"Infusing sleeping pills into a baby is almost impossible, unless there is this." Ling Mo said, "If traces of sleeping pills are found in this baby bottle, do you still have the conditions to deny it?"

The air condenses.This is a harbinger of victory.

Suddenly, the peaceful air was broken by Yin Zhaodi's low cry.

She knelt on the ground, and in order not to let Meng Jiaojiao outside the door hear the abnormality, she begged in a low voice: "Brother, please don't report on me."

"I'm not reporting on you, I'm the police, and it's my duty to find the real culprit." Ling Mo said.

"Brother, you will never understand my pain." Yin Zhaodi pulled open the front of his clothes, exposing his chest, Ling Mo instinctively avoided his eyes.But even so, Ling Mo still saw the dense keloids on her chest at that moment, which was shocking.

"Every day, almost every day, Yin Jie would prick me with a silver needle." Zhaodi Yin had no tears at this time, his eyes were full of determination, "Do you know? At that time, I was only three years old! Crying heartbreakingly, my mother also crying heartbreakingly, but no one dared to stop him, he just stabbed me day after day. There is only one simple reason for stabbing me, that is, he listened to what others said , Said that the thousands of needles on a daughter's body can be exchanged for a son in the next child! Is it ridiculous?"

Ling Mo's heart tightened.

"I don't know how much blood I bleed, and I don't know how much pain I have suffered from being abused!" Yin Zhaodi said, "The experiences of abused children reported in many news reports are tens of thousands of times better than mine, right? But I, I can only bear it silently. God has no eyes! He actually gave him a son from the Yin family!"

"So when you had a younger sister, you were unbalanced and stabbed her too?" Ling Mo asked.

"No no no." Yin Zhaodi shook his head vigorously and said, "I love my little sister very much, but I told her that maybe she will be riddled with silver needles in the future, so it's better to get used to the pain now. But, Every time I pricked her, she would cry desperately, heart-piercingly, she was not as strong as me at all."

"On the day of the incident, some neighbors did hear crying." Ling Mo said, "So in order not to let her cry, you covered her mouth and nose, and she suffocated to death. You were very scared, so you threw her into the However, this crime has taught you a lot, first, you are not so afraid, so you will show the exhibitionism in your heart; second, you have learned to use sleeping pills to stop the baby from crying."

"I really didn't want to kill them." Yin Zhaodi said, "They are still young, but when they are three years old, they will definitely be stabbed with thousands of needles and suffer greater pain. It is better to adapt now."

"I believe." Ling Mo said, "You're a junior high school graduate, so you definitely don't know that a ruptured pleural membrane can lead to pneumothorax, which is life-threatening, and a one-year-old baby has an unclosed fontanel on the top of its head."

"Brother, can you help me?" Yin Zhaodi knelt in front of Ling Mo, supporting her knee, "I swear I will never do this kind of thing again! As long as you throw away this milk bottle, no one will know I did it. Yin Jie is dizzy every day, if he is caught, he will definitely be recruited soon, even if he doesn't, the scars on my body are enough to convict him."

Ling Mo frowned and said nothing, but there was a huge ripple in his heart.

Why not himself?Let alone a happy childhood, there were only shadows in his childhood.When he was a child, he was hung from a branch of a tree by the door for a day and a night, he was beaten to the point of being bruised all over his body by a belt with a belt buckle, and a toothpick was poked through his fingernails... All these things have been suppressed in his heart for more than ten years.

At that time, Ling Mo did not resist, but how could his weak body resist the hard whip?Since you can't choose to resist, choose to escape.But how easy is it to escape?Looking for food discarded by others in the garbage dump, the smell on my body can make me vomit, bear the contempt or defensive eyes of others, and do illegal things and be chased by the police...

Yes, I am a boy and I can't bear it, let alone this weak girl in front of me?

In the face of brutal domestic violence, how should she choose?Where does she have the ability to choose?
At this moment, all these emotions gushed out, and he couldn't remain indifferent to everything in front of him.At the beginning of the investigation of the case, in Ling Mo's mind, the murderer had a green face and fangs, but at this moment, the lovely and pitiful little girl in front of him was the real murderer.Her tragic experience and the shocking scars on her body made Ling Mo momentarily at a loss as to what to do.

Yes, as long as the bottle is disposed of, there is absolutely no evidence that the poor little girl is guilty.

"Please... brother." Brother Yin Zhao continued to beg.

There was another long silence.

Ling Mo slowly took out the photos of the three victims from his pocket, and slowly laid them out in front of Yin Zhaodi.

"Look at them." Ling Mo spit out these words word by word.

Yin Zhaodi was obviously greatly stimulated by the photo, and suddenly collapsed to the ground.

"If you don't accept legal sanctions, can your conscience be soothed?" Ling Mo said, "They should have their own lives, but when they don't understand human affairs, their lives come to an abrupt end. Why do you choose for them?" ?”

Yin Zhaodi bit his lip, his eyes were already red.

"No hurry, I'll wait for you to figure it out." Ling Mo stared at Yin Zhaodi and said.Yin Zhaodi was still sitting quietly on the ground, and he also sat beside her.She endured her own sobs, until Ling Mo patted her shoulder lightly, and Yin Zhaodi's tears flowed down like a heavy burden.

In this way, half an hour passed without knowing it.Nie Zhixuan suddenly appeared at the door of the living room. He happily held up a large evidence bag with his prosthetic limb, which was full of mud. He walked in and said loudly, "I found it!"

Seeing Ling Mo and Yin Zhaodi quietly sitting side by side on the ground, Nie Zhixuan was taken aback, not understanding what was going on.

"How is it?" Ling Mo turned to Yin Zhaodi and said.

"I'll go with you." Yin Zhaodi slowly supported his body with his trembling arms and stood up.Ling Mo gestured to Nie Zhixuan, and stood up accordingly.But he still has one question that hasn't been answered.

"Brother Yin Zhao, you haven't answered my first question yet."

"That question... I don't know either." Yin Zhaodi said frankly, "I heard from my mother that when I was one and a half years old, I went to get vaccinated once, and suddenly I couldn't sit up when I came back. My mother thought I was paralyzed. I went to the epidemic prevention station to investigate the responsibility. But, I don’t know why, I suddenly recovered. After recovering, I knew that my jumping ability was different from other children when I was young. space, so no one else knows.”

"So..." Ling Mo was thoughtful.

"Answer me a question too," Yin Zhaodi bit his lip and asked seriously, "Will Yin Jie...will go to jail?"

"Crime of cruelty, neither the people nor the officials will prosecute. As long as you are willing to sue, he will definitely accept criminal punishment." Ling Mo also replied seriously.

"Okay, let's go."

Yin Zhaodi seemed to have calmed down a lot, and silently followed Ling Mo out of the hut, leaving a stunned Nie Zhixuan standing at the door holding a large evidence bag.When he walked out the door, Ling Mo glanced at Yin Zhaodi silently, thinking about what she said just now: he had a "vaccination" when he was one and a half years old, and suddenly he couldn't sit up when he came back...

There is no such thing as a coincidence in the world.
