Night's Watch 2: Dark Potential

Chapter 8
The hardest thing for people to do is to be consistent, and the easiest thing to do is to be fickle.

——(France) Montaigne

The case was solved smoothly and quickly again, making the Night Watcher organization famous.As for the abnormal phenomenon in the last case, the night watchmen took a roundabout tactic and found other breakthroughs to solve the case, which also made the police admire.

Although the case was solved, the handover of physical evidence, the explanation of the case and the development of the interrogation still made the members of the organization work late into the night.

After Xiao Lang returned to the dormitory, he fell asleep, but he didn't feel like he had slept for long, when he was awakened by a sudden knock on the door.At the door was Ling Mo who had already freshened up.

"It's just dawn, what's wrong with you?" Xiao Lang grabbed his messy hair.

"Yesterday we agreed to see a psychologist, did you forget?" Ling Mo shook his head helplessly.

"As long as I'm in ambush, I won't get involved in the affairs of you mind readers." Xiao Lang quickly ran back to bed.

"We don't have a car." Ling Mo said.

"What's none of my business?" Xiao Lang's voice came out through the quilt, buzzing.

"You have as much doubts about the 'Ghost Rider' case as I do."

"There is no doubt now, nothing is more important than sleeping." Xiao Lang said.

"That's good." Ling Mo turned around and closed the door, "Dangdang and I will take a taxi."

"Wait a minute, wait a moment." Xiao Lang sat up abruptly, "Dangdang is going too?"

Ling Mo nodded with a half-smile.

"Give me 5 minutes, I'll drive." Xiao Lang picked up his pants and took three seconds to put them on, "It's so remote here, don't take a taxi, it's so expensive."

In less than 5 minutes, Xiao Lang's Chery car caught fire.

"I don't understand, it's only seven o'clock! Why do psychologists go to work so early?" Although Tang Dangdang was sitting in the back row, Xiao Lang was still brooding over the destruction of his lazy sleep.

"No way, people only have time in the morning." Ling Mo said.

"I don't understand. Isn't Teacher Tang a psychologist? Why are you looking for someone else?" Xiao Lang chattered.

"My dad is a psychoanalyst, not a psychotherapist. For hypnosis, Mr. Jiang is more professional." Tang Dangdang said, "I don't understand. Why don't you understand so much? If you don't go, now It's not too late to turn off the flame."

"Go! I've already woken up, it's a good thing if I don't go anymore." Xiao Lang said, "I'll call wherever your eldest miss points."

"Hmph." Tang Dangdang gave Xiao Lang a blank look.

"By the way Dangdang, does the teacher know anyone who specializes in preventive medicine?" Ling Mo asked suddenly.

"Preventive medicine?" Tang Dangdang was puzzled.

"It's the CDC, epidemic prevention stations, vaccine companies and so on?" Ling Mo explained.

"Oh, Ling Mo, you want dogs to catch mice again." Xiao Lang interjected.

"Yes, isn't Aunt Cui the vaccine research and development company?" Tang Dangdang said.

"Who is Aunt Cui?" Ling Mo thought for a while and realized that he did not know this person.

"Aunt Cui Zhen." Tang Dangdang tilted her head and said, "Oh, you may not know her. She is a good friend of my dad and used to come to my house often."

"Can you give her a call? I have a question to ask." Ling Mo said.

Tang Dangdang nodded and dialed a series of phone numbers.After the call was connected, she said a few words and handed the phone to Ling Mo.

A middle-aged woman's voice came from the other end of the phone.

"Hello."

"Mr. Cui, hello, I'm Teacher Tang Jun's student, Ling Mo." Ling Mo said, "I'm looking for you to ask a question. I wonder if you paid attention to the two things about vaccines a few days ago?"

"Well, I know what you're talking about." Cui Zhen paused with a smile on the phone, and then said, "I've been on the hot search several times in the past two days, and they can say everything. Some people think that the vaccine may Humans have turned into zombies. However, to be honest, there is no basis for this panic. The investigation team has come to our company to take samples several times, and the test results have proved that the vaccines are all qualified and there is no problem. In fact, from a medical point of view , any vaccine is unlikely to cause side effects of overgrowth or severe coma. If the first news event is a coincidence, then the parties involved in the second news event are actually influenced by psychological hints to a certain extent. In fact It has nothing to do with vaccines."

"However, I met a friend recently. She said that she was paralyzed for a while after being vaccinated, and after recovering, she developed symptoms of super strong jumping ability. This..." Ling Mo continued to ask in doubt.

Cui Zhen's patient voice came from the other end of the phone: "Your friend's situation sounds really miraculous. If you are worried, you can also ask her to contact me, and I can arrange a colleague to do a test for her. After the news was published, we received a lot of samples requiring testing. A large number of people were affected by the news and suspected that they had adverse reactions. But so far, no one has been tested to be really problematic. In my opinion, this It can be regarded as a kind of herd effect[25]—of course, your teacher Tang Jun studies psychology, and he should explain it more professionally than me.” Cui Zhen smiled softly again.

"En." Ling Mo seemed to be relieved, thanked Cui Zhen, and hung up the phone.

Even if they set off at seven o'clock, they still couldn't avoid the morning rush hour in Nan'an City.It took Chery more than an hour to arrive in front of an office building, 15 minutes later than Ling Mo's appointment time.

The three of them went up the elevator to the 19th floor side by side. When the elevator door opened, they saw a semi-circular front desk. The background of the front desk was a signboard that said "Jiang Qi Psychological Consultant Firm".

A stylishly dressed young and beautiful girl walked around the front desk to greet her, and said enthusiastically, "Excuse me, Mr. Ling and Ms. Tang, right? Teacher Jiang has been waiting for you for a long time."

Xiao Lang said awkwardly: "There is also Mr. Xiao. You are so beautiful that you are almost blind. Didn't you see that there is another Mr. Xiao?"

The girl didn't think it was disobedient, and instructed them to enter the office area with a standard welcome gesture.

Xiao Lang thought that Tang Dangdang had heard him praise the girl, so he walked into the corridor and hurriedly explained to Tang Dangdang in a low voice: "Although that girl is not ugly, compared with our young lady, she is really a world of difference."

Tang Dangdang looked puzzled.

Jiang Qi heard footsteps at the door, opened the door and came out to greet him: "Ling Mo, you are here. Hey, I haven't seen you for a few years, we Dangdang are really beautiful and charming."

"Hello, Auntie." Tang Dangdang took Jiang Qi's hand.

"Miss, it's inappropriate for you to call her auntie? At best, she's a big sister." Xiao Lang said.

Jiang Qi in front of him was wearing a work suit, with a well-proportioned figure and an extraordinary demeanor.Although she doesn't look very young anymore, she has a noble, dignified and beautiful temperament.

"Who is this young man?" Jiang Qi asked with a smile.

"Oh, my colleague, Xiao Lang." Tang Dangdang said.

"Colleague?" Xiao Lang was very dissatisfied with this title.

"Xiao Xiao is very good at talking." Jiang Qi said, "Please come in."

After taking a seat in Jiang Qi's office, Ling Mo cut straight to the point: "I'm sorry, Mr. Jiang, we are late. Your time is precious, so I'll make a long story short. Did you read the materials I gave you last time?"

Apparently, Ling Mo had provided Jiang Qi with relevant information about "Ghost Rider" in advance.

Jiang Qi nodded: "What do you want to ask?"

"The question is very simple. Actually, is it possible for one person to hypnotize more than [-] people at the same time?" Ling Mo asked, "Or, his heterochromatic iris helped him to have such ability?"

"Hypnosis is a kind of suggestion." Jiang Qi said, "People enter a special trance state, and then follow the instructions of the hypnotist to perform specific behaviors or produce specific feelings. In the classification of hypnosis, there are indeed' In the category of group hypnosis, there are indeed people who have the ability to hypnotize hundreds of people at the same time. As for whether his heterochromatic iris is helpful for hypnosis, it’s hard to say. Because people who can perform group hypnosis don’t have special looks.”

"It's really unbelievable. How can one person control so many people? How terrifying would it be for these hypnotists to enter the battlefield?" Ling Mo said.

"Oh, it's not what you imagined." Jiang Qi said, "Whether it's individual hypnosis or collective hypnosis, it needs the active cooperation of the hypnotized person, or there must be specific environmental conditions and hypnosis process."

"Then in the case I showed you, are there any specific environmental conditions? Is there a specific hypnosis process? Is it possible for the prisoners to actively cooperate?" Ling Mo asked.

"No, no." Xiao Lang said, "When I was confronting him, he hypnotized me. It was impossible for me to actively cooperate with him. Besides, the moon was dark and the wind was high, what environmental conditions could there be?"

"That's what I want to talk about today." Jiang Qi said, "This case is still strange. Hypnosis, in fact, is a guidance of a hypnotist. Under the circumstances that dozens of people will not cooperate wholeheartedly, using hypnosis techniques to let These dozens of people obeyed the instructions and did such a bold and complicated thing, and they didn’t know it afterwards. This, I think the hypnosis technology at this stage is still not up to it.”

"That is to say, there is no way to complete this process now." Ling Mo said, "Then, can I understand that this particular hypnotist is different from others?"

"The heterochromia you mentioned may be a point." Xiao Lang said, "I saw his eyes without white eyeballs, and I was immediately hypnotized."

"Of course, this is definitely not the key point." Jiang Qi said with a smile, "You can't even see the white eyes of a dog. Will you be hypnotized when you look at a dog's eyes?"

"And beauty, you just said that there must be a specific environment and process. I was almost hypnotized by his words." Xiao Lang said.

"It's not big or small." Tang Dangdang reprimanded.

"So, hypnosis is a man-made technique, a psychological technique." Jiang Qi said, "In the final analysis, it is completed by man-made psychological intervention, and this technique does not involve physiology."

"You mean that this person's method is not hypnosis?" Ling Mo asked.

Jiang Qi shook his head and said: "It is hypnosis to make people in a trance state, faithfully execute other people's orders, and not know about the incident afterwards. What I mean is that if there is a physiological abnormality, this abnormal factor can speed up the process. , streamlining the hypnosis process, and even strengthening the hypnosis effect can achieve the final effect of this case. Otherwise, from the perspective of the hypnosis mechanism, such a case is a fantasy."

"Physiological reasons have greatly strengthened and optimized the psychological technology, is that what you mean?" Ling Mo asked.

Jiang Qi nodded.

"But, what kind of physiological reasons can strengthen and optimize hypnosis?" Ling Mo lowered his head and frowned.

"It's time to ask medical experts." Jiang Qi said, "But I believe that this is definitely a very rare special case and will not be a common phenomenon."

"I just said Brother Nie's examination was hasty." Ling Mo rubbed his temples.

Xiao Lang opened WeChat as if playing a prank, and sent a voice message to Nie Zhixuan: "Brother Nie, Ling Mo speaks ill of you."

Soon, Nie Zhixuan replied on WeChat: "I think you are talking bad about me."

"Really, he said your dissection of 'Ghost Rider' was flippant."

"Who said I was rash? I just wanted to find you!" Nie Zhixuan's voice sounded urgent, "Where are you? Is it convenient for Fang to come to the Nan'an Public Security Bureau now?"

In the DNA laboratory of the Nan'an Public Security Bureau, Nie Zhixuan and Fu Ruxi were looking at a DNA profile.Seeing Ling Mo and Xiao Lang walk through the door, Nie Zhixuan turned on the computer, and a dissection photo of a human brain appeared on the screen.

"Is this from 'Ghost Rider'?" Ling Mo, who couldn't wait for the elevator, climbed up the ninth floor in one breath, said out of breath.

"It's not good for a small body." Xiao Lang dragged an experimental wheelchair and stuffed it under his buttocks.For Xiao Lang, climbing up to the ninth floor will not affect his blood pressure and heart rate.

"Can you see something?" Nie Zhixuan asked Ling Mo and Xiao Lang with a smile.

"Oh, I won't be able to eat my brain anymore, it's too similar." Xiao Lang said with a frown.

"I don't see it, it seems to be nothing." Ling Mo also shook his head and said.

Nie Zhixuan picked up the mouse, and used the image marking software to frame an area of ​​the photo with a red frame: "Look here."

"A little whiter?" Xiao Lang asked.

"No, the technical term is 'the shallowing of the sulcus in the local tissue of the brain'." Nie Zhixuan said.Although forensic science is also included in the training courses organized by the Night Watchers, forensic science is really extensive and profound, and requires a medical foundation, so it is impossible to train everything.This kind of practical and detailed knowledge points is still not mastered by a non-medical student.

"Brother Nie, don't be devious, just tell me, did the police make a wrong case?" Xiao Lang said.

"Don't talk nonsense, it can only be said that there are doubts, why did you handle the wrong case?" Fu Ruxi blamed Xiao Lang with a smile.

"My mother was right and the police were wrong, right?"

"This has nothing to do with who killed the 'Ghost Rider'." Nie Zhixuan said, "However, it seems to have some hints about the background of the 'Ghost Rider'. However, I haven't figured out what it can hint specifically."

"This ditch has become shallower, do you have any explanation?" Ling Mo brought the topic back.

"That's right, since you found something abnormal during the autopsy, why didn't you report it to the police?" Xiao Lang asked.

Nie Zhixuan knew Xiao Lang's reckless character very well, so he didn't mind his rude words.He smiled and said: "Actually, in terms of forensic science, this abnormal area doesn't make much sense. During the autopsy, the forensic doctor clearly ruled out other causes of death of the 'Ghost Rider', and the cause of death was infusion through the intravenous channel." He died of cyanide poisoning. Because the third cervical vertebra was shattered by a bullet, the corresponding cervical spinal cord was damaged, and the cavity effect[26] caused contusion of other blood vessels and nerves in the neck, and he was in a vegetative state. Therefore, this This kind of poisoning belonged to others, and it was a homicide. This is all the forensic doctor can do. Even if there is such a mutation area in the brain, it is meaningless to the entire "Ghost Rider" murder case. After all, this Not a fresh injury."

"But you pay attention." Ling Mo said.

Nie Zhixuan's mechanical arm was creaking. He took a sip from the teacup, and then said: "At that time, I thought this area was a softening stove[27]. Influence, but maybe it can give some hints to his history or background."

"What reminder?" Xiao Lang sat up straight.

"Look, the brain tissue in the mutated area is located on the side above the falx [28]." Nie Zhixuan paused, thinking that the words were too professional and they couldn't understand them, so he changed the subject, "To put it bluntly, This abnormal region affects the function of the cerebral cortex, which may lead to abnormal electrical discharges in the brain and epilepsy."

"What's the use of knowing he has epilepsy?" Xiao Lang said.

"After all, the real and legal identity of 'Ghost Rider' has not been clarified yet." Nie Zhixuan said, "I am thinking that this may at least become a basis for later investigation of the true identity of 'Ghost Rider'."

"Abnormal discharge." Ling Mo pondered.

"That's right." Xiao Lang didn't notice Ling Mo's concern, and said, "And the reason for the formation of the softening stove can also be the basis?"

"There are many reasons for the formation of softening lesions." Nie Zhixuan said, "It may be left over from trauma, it may be left over from cerebral infarction, or it may be affected by drugs, or it may be a congenital mutation. So, what is the reason? It’s hard to judge.”

"Is that the softening stove?" Xiao Lang said.

Nie Zhixuan opened another picture. This picture was not an autopsy photo, but a light red background with blue dots inside.Ling Mo and Xiao Lang, who had basic biological knowledge, said in unison: "Oh, pathology slides."

"This is a routinely stained pathological slice of brain tissue." Nie Zhixuan said, "After I found a problem during the autopsy, I took out this abnormal tissue and came back for pathology. Judging from the slice, it is not It is not a softening lesion, but what it is specifically, I asked many experts, and they all said that they have never seen it. In the brain tissue area of ​​'Ghost Rider', the brain tissue around the blood vessels is loose, the nucleus of the brain nerve cells is pyknotic, and the neurons are swollen, Deformation. It is unknown what caused the change."

"Could it be brain cancer?" Xiao Lang interrupted.

"Yes, I also thought about it at the time." Nie Zhixuan said, "Then, I performed immunohistochemistry on this tissue. You don't need to know what immunohistochemistry is. As a result, I used a specific protein When using the markers, I found another protein form that I had never seen before. Of course, I also consulted experts in related fields, and none of the experts had seen this type of protein.”

"That is to say, there is an abnormal tissue in the brain of 'Ghost Rider' that has not been discovered before?" Xiao Lang translated.

Nie Zhixuan nodded vigorously a few times, and said: "At this time, I heard from Sister Fu that you had come to consult about genes, and it was also about 'Ghost Rider'. This piece of brain tissue was genetically sequenced. The conclusion is that this piece of tissue is caused by the genetic mutation of 'Ghost Rider' itself. What happened to 'Ghost Rider'."

"Aunt Fu! Not Sister Fu!" Xiao Lang corrected, "That is to say, if this place changes suddenly, his function will definitely change? Brother Nie said before that what part of the brain is responsible for what function, this time Now that we know the specific parts, can’t we deduce the functions that he may affect?”

Nie Zhixuan made a "please" gesture, signaling for Fu Ruxi to teach.

"Humans have 23 pairs of chromosomes. The human genome contains about 30 billion DNA base pairs, and there are 2 to 3 genes. The specific sequence of the genome determines the shape, characteristics and functions of human beings." Fu Ruxi looked at her beloved little girl with a smile. Son, said, "Currently, the complex relationship between most of the genome sequence and human shape, features and function has not been understood."

"We may know the function of the brain partition, but we cannot fully understand what function will be affected by the mutation." Nie Zhixuan said.

"You just mentioned abnormal discharges." Ling Mo said, "We have consulted with a psychologist. She thinks that the hypnosis of 'Ghost Rider' is not normal hypnosis, and there may be biological factors affecting this psychological intervention method."

"However, the brain wave of the human brain is a kind of extremely weak bioelectricity." Nie Zhixuan said, "It stands to reason that it is impossible to affect others because of the strengthening of this bioelectricity, unless..."

"Unless what?" Xiao Lang asked eagerly.

"If his brain waves are enhanced hundreds of times due to this gene mutation, it can affect other people's mirror neurons." Nie Zhixuan said.

"What is a mirror neuron? Brother Nie, don't be silly, tell me, tell me quickly."

"Humans have a group of nerve cells called 'mirror neurons' that inspired our primitive ancestors to step away from apes. Its function is to mirror the behavior of others, allowing people to learn from simple imitation to more complex imitation, thus Gradually developed language, music, art, use of tools, etc. This is one of the greatest aspects of human progress."

"That is to say, if a special brain wave change of 'Ghost Rider' affects the mirror neurons of others, it can prompt others to imitate his behavior." Ling Mo said, "Combined with hypnosis, the whole process can be completed. process."

"This is my wild guess, and there is no scientific basis to prove it." Nie Zhixuan spread his hands.

"Could it be that someone has modified the 'Ghost Rider''s gene so that his genetic evolution has such an ability?" Xiao Lang asked.

"As I said just now, the complex relationship between gene sequence and function has not been clarified. Even the part that has been clarified cannot be changed at will through artificial means. Although the existing technology of artificially promoting gene mutation at a specific point can make the gene Mutations, but they cannot all correspond to which specific sequence is related to which function, and which function cannot be absolutely 'evolved', because gene mutations may also cause 'degeneration' or 'change'; and even if a cell is changed It is difficult to change all the cells of a tissue. Therefore, it is not possible to purposely promote gene evolution to enhance human functions." Fu Ruxi said, "I told you the difference between 'evolution' and 'evolution' before, do you remember? "

"It seems that we are thinking too much." Ling Mo said, "Modern science cannot promote the evolution of others and organize an evolutionist army."

"Your idea is quite creepy." Nie Zhixuan said.

"I've always had such doubts." Ling Mo didn't seem to give up his thoughts yet, "After all, there might be an organization behind 'Ghost Rider', this idea is not outrageous."

"Then what if someone is looking for these people with 'special abilities' and organizing troops?" Xiao Lang said.

"Impossible." Nie Zhixuan said, "If the 'Ghost Rider' has not received special training, even if he has such an innate ability, it will not be effective. If it is not effective, then others will not know that he has such an ability. It’s an endless loop. Also, since he found a protein in his brain tissue that he hadn’t seen before, I always feel that there is still an artificial factor intervening.”

"Or, has someone really researched a way to purposely modify human genes and lead to human evolution?" Xiao Lang said.

"If it is true that this technology can be widely used in various industries, it will be an unprecedented biological revolution. Such researchers can have wind and rain, and why should they organize An army, to escape and kill people?" Fu Ruxi said.

"In any case, we have made new progress." Ling Mo said, "One day, we will be able to reveal the 'Ghost Rider' and the people behind him."

"What we are going to watch today is a murder case." Fu Yuanman walked to the back of the podium and operated the computer to open a case analysis PPT (slides) produced by the Bei'an Public Security Bureau.

Hearing that it was a murder case, the members of the Night Watch sat up straight unconsciously.

As a neighboring city of Nan'an City, whenever there is a disturbance in Bei'an City, Nan'an City will also hear about it.After all, in this era, the rate of homicide cases has dropped to a historically low level, coupled with the spread effect of self-media, so once this vicious murder case occurs, it will soon spread widely.

Although the case happened three years ago, and the members of the Night Watch were ordinary students in various schools at that time, they had all heard of this appalling case of killing five people.Moreover, everyone knows that shortly after the incident, there were rumors that the case had been solved.

The case spread so widely, and there were fatal problems in the investigation and prosecution stage of the case, so the case was handed over to the Night Watch organization after three years of delays and failed to successfully prosecute.

"Isn't this case solved?" Xiao Lang said.

"What we call solving a case generally means that the public security department has arrested the criminal suspect and brought him to justice, and there is evidence to prove the criminal behavior of the criminal suspect." Fu Yuanman said, "However, after the case is solved, can the prosecution, trial, and conviction , there are still variables. There is always such a one in ten thousand probability that some cases cannot be prosecuted or acquitted due to unclear facts and insufficient evidence. Of course, these cases that cannot be prosecuted or acquitted are not It means that the suspect is really innocent. A verdict of not guilty does not mean that he is actually innocent.”

"I understand this, and there is no doubt about it." Xiao Lang said, "The spirit of the rule of law."

"Is there a problem with the evidence in this case?" Ling Mo asked.

Fu Yuanman frowned in a rare way, and said: "In fact, this case seems to have sufficient evidence on the surface, but in fact there are still many doubts. Therefore, the cases you have heard before are all rumors among the people. The case has not been announced to be solved. Even in the process of handling the case, the public security organ applied to the procuratorate to intervene in advance, but the result of the intervention is that the facts of this case are unclear, the evidence is insufficient, and the conditions for prosecution are not met.”

"Then let's listen to it." Nie Zhixuan said with interest.

According to the sequence of the PPT produced by the Bei'an Public Security Bureau, Fu Yuanman introduced the cause and effect of the case in detail.Apparently, the local Public Security Bureau came here to report the case to him, because the PPT only stated objective facts without any tendentious views.

The case happened more than three years ago.

When the spring of 2014 was warm and the flowers were blooming, a shocking murder occurred in a dark hotel.

The scene of the crime was in a "slum" in the southern suburbs of Bei'an City.Because the original site of Bei'an City Municipal Hospital was in the city center, the downtown area was congested every day. Therefore, the government and the hospital negotiated to acquire a piece of land for the hospital in the southern suburbs. As a replacement, the government assisted in the construction of a new city hospital.After the establishment of the hospital, housing prices rose, resulting in the failure to reach a compensation agreement for a large area of ​​bungalows opposite the hospital, and thus could not be demolished.Residents in this bungalow area attached themselves to the hospital and each started a small business.Some do snacks and breakfast businesses, some run small restaurants, some sell daily necessities for hospitalization, and some open black hotels.

The scene is in the middle of this bungalow area. The owner is Zhao Yuan, 63 years old.

Although it is a black hotel, it means that there is no corresponding business license, but the boss is not black.Zhao Yuan and his wife are loyal and helpful, and have a good reputation in this "slum".It is said to be a "slum", but it is actually a large area of ​​one-story houses artificially built by farmers living in the urban-rural interface after decades of changes.This area is densely populated, houses are densely packed, and the passages are narrow. It has always been the place with the greatest safety hazard in Bei'an City.However, because the demolition funds demanded by the local people were sky-high, no developer dared to pay any attention.As a "local tyrant" unit, the municipal hospital was seriously injured after acquiring part of the land. If it wanted to continue the land acquisition, it found that it was already powerless.

In order to deter crimes to the greatest extent, the public security department also installed a lot of camera probes in this area, but after several years, these camera probes were destroyed by the local people, and only a few of them were left usable.Fortunately, they are all neighbors, so there is no vicious crime here, at most it is some petty theft.

The center of the bungalow area used to be the homestead of Zhao Yuan and his wife. They built eight bungalows here. Although it is not the most real estate in this area, it is more than enough to open a small hotel.The business here is mainly for the hospital, and the regulations of the municipal hospital are that family members are not allowed to stay in bed at night.The transportation in this area is extremely underdeveloped. For the sake of convenience, the family members of patients from various districts and counties who come here to be hospitalized find a small hotel in the bungalow area opposite the hospital.Therefore, the family members living in the hotel often stay for ten days to complete the task of serving patients.

The black hostels with the best business in the bungalow area should be the few on the edge of the area, facing the hospital, after all, they are the closest in terms of distance.Zhao Yuan Hotel, located in the center of the area, has a tepid business.But the neighbors all said that after all, there are no repeat customers near the hospital, and if business depends on repeat customers, Zhao Yuan's family should be the best.Because Zhao Yuan is very kind to his tenants. In addition to cleaning the room regularly every day and giving fruit plates, he often helps the tenants with cooking and laundry. This kind of super high-quality service makes the tenants stand up. thumb.

In Zhao Yuan's words, the family members who can come to serve the patients are all filial.Especially those young people who come to serve their parents are very rare in this age.Therefore, the younger the tenants were, the more meticulous Zhao Yuan took care of them.Of course, this also stems from the fact that Zhao Yuan’s only son died in a car accident ten years ago, and an old couple depended on each other for their lives, and they would always have a sense of substitution when they saw young people and seemed more cordial.

However, the murder happened to this kind-hearted boss.

The reporter was a 70-year-old man named Zhao Dahua.Zhao Dahua is Zhao Yuan's distant relative, so the homesteads are all next to each other.Zhao Dahua would sit at the door of her house and listen to the radio every day for a whole day.Only on Tuesdays, Zhao Dahua would go to her son's house in the city to help clean up once.The door of Zhao Dahua's house is actually the door of Zhao Yuan's house, so Zhao Dahua knows every move of Zhao Yuan's house well, but he never thought that the crime happened on Tuesday.

On Wednesday morning, when Zhao Dahua came back from the city, she found that the gate of Zhao Yuan's courtyard was open, and the light box with the words "Zhao Yuan Hotel" on the door was shifted.Out of concern, Zhao Dahua called Zhao Yuan's name a few times, but there was no response.This kind of phenomenon is extremely rare, because when Zhao Yuan is not at home, Fang Kexia, Zhao Yuan's wife, will agree to her when she is at home.So Zhao Dahua had doubts, opened the door and entered Zhao Yuan's courtyard.

Zhao Yuan's house is a small courtyard, and it is not accurate to say that it is a courtyard, because there is no decent courtyard.Eight houses, four or four facing each other, are distributed on both sides of a two-meter-wide aisle, and the houses are also connected.In this way, the eight houses, the front door and the rear wall form a small courtyard.Zhao Yuan and his wife lived in the house at the front gate. There was a window with iron bars facing the gate, which was regarded as a reception.This is like a guest house. There is usually such a concierge at the gate. Tenants can push open the automatically closed courtyard door to enter the courtyard, communicate with Zhao Yuan at the concierge, and then pay money to get the key to the room they opened.

Among the eight houses in the hostel, except for the one where Zhao Yuan and his wife lived, the opposite one was divided into toilets, showers and kitchens, which were shared.Among the eight houses, these two are the largest, each about [-] square meters, while the other six houses that can be used for tourists are only [-] square meters each.

Walking into Zhao Yuan's courtyard, Zhao Dahua had an ominous feeling.Because on the central aisle in the courtyard, it seems that some bright red traces can be seen, like blood footprints.

After all, it was early in the morning, and the sun slanted into the porter's window from the porter's window.Zhao Dahua found that the original curtains of the concierge had been torn down, and the floor of Zhao Yuan's residence was covered with bright red blood, and all the places in the room that could store items had been opened, the money box was knocked over on the ground, and the early morning money was thrown away. The reflection of the sun was extremely dazzling.In the shadow of the wall and the door, there seemed to be something dark, but Zhao Dahua had long lost the courage to take a closer look. She ran back to her home and called the police with a landline.

The first batch of police officers from the police station who came to verify the situation did not expect such a big case to happen in their jurisdiction.A total of five people died in this case.In addition to the large number of deaths, the case is also very bad, because five people were covered with plastic scotch tape all over their bodies, and each of them was "beheaded".

The central scene is in the [-]-square-meter bungalow where Zhao Yuan and his wife lived. The clean and tidy room has been completely turned upside down, and the white floor tiles are covered with blood.There were huge pools of blood under the bodies of the five corpses.

The five people who died were Zhao Yuan, Fang Kexia, and three tenants.Among the three tenants, one is Feng Qi, a middle-aged man in his 50s, who rented here because his wife was hospitalized with breast cancer.Feng Qi was a laid-off employee of a real estate company in Beiyuan County, Bei'an City. After being laid off, he worked in a chicken farm with a modest income.The other two tenants are a young couple in their 20s. The man's name is Li Jiangjiang, and the woman's name is Cheng Yuan.The young couple are farmers in the suburbs of Bei'an City, but they usually work in the city.Li Jiangjiang's mother was hospitalized due to cerebral hemorrhage, and Li Jiangjiang couldn't take care of her alone, so he and his wife took leave of absence from the construction site to take care of his mother near the hospital.

The five people were covered with tape all over their bodies, and they were neatly arranged on the ground of the central scene, like five silkworm chrysalis, with a terrifying shape.If you look closely, you can see that there is a huge cut in the middle of everyone's neck, and a lot of blood on the scene is gushing out from here.

The two police officers from the police station had never seen such a vicious case in their entire lives, so they quickly put up a cordon around the scene and immediately notified the criminal police detachment of the Municipal Public Security Bureau to come to the scene for support.

For the criminal police, the most fearful thing is some robbery and homicide cases that commit crimes.Although the detection rate of such cases is very high, the efforts of the criminal police are also very large.Therefore, when entering the scene of a vicious homicide, the criminal police are most concerned about whether the case is committed by an acquaintance.

Although this kind of on-site environment and this kind of severely disturbed scene situation can often be seen in cases of robbery and homicide, the criminal technical police quickly gave the criminal police a reassurance.Although there were a lot of bloodstains at the scene, which covered the dust and layered footprints[29], all the bloodstains on the scene were slippers prints, and all the slipper prints of the blood footprints did not belong to the five deceased.Moreover, the three pairs of slippers that left the slippers marks were still left at the door of the house at the center site.Such clues are very valuable, and at least four problems are explained: [-]. When the criminals walked around after killing people, they wore slippers, and they changed their shoes when they left.Second, there may be three perpetrators.[-]. Because the shoes are changed at the concierge, they are not guests staying in the hotel.When four or five of the dead were brought under control, there was not a lot of bleeding.

What kind of fugitive would change his shoes when he comes to rob?
Another group of criminal technologists was quick to come to the same conclusion.

The task of this group of police on-site investigation is to find a camera probe that can be used nearby.Although there was no camera probe near the scene area, the careful police still found a camera probe installed at the corner of the roof of the gate house.This camera probe is directly facing the window of the concierge, that is to say, anyone who stays at the window, asks questions, stays in the hotel, pays bills, etc., will leave images.This discovery is really very valuable.After investigation, this camera probe was connected to the computer in the concierge, but after the police inspected the computer, they found that the recording of this camera probe stopped abruptly at 06:30 on Tuesday afternoon, that is to say, the recorded Before sending out, someone cut off the power of the camera probe.

Because all the wires are exposed, the police can easily find that the power supply of the camera probe is connected to the light box outside the courtyard through the roof, and then run together to get power indoors.If someone cuts the wire at the light box outside the courtyard, the camera probe will stop working.The police didn't know why Zhao Yuan used such a stupid way to connect, but the police knew why there were signs of movement on the light box of Zhao Yuan's hotel.

Although the traces of gray layer reduction on the light box suggested that the murderer was wearing gloves, and no fingerprints and DNA could be extracted, but at least it showed that the murderer was very familiar with the environment of the scene, and knew the location and connection of the camera probe well.The camera probe recorded until 06:30 pm on Tuesday, and the previous records were still stored in the computer. The murderer did not destroy the computer, which shows that he is sure that his images have not been stored in the computer.If you didn't "step on the spot" at the concierge, were familiar with the scene environment, and had a good understanding of the situation of the camera probe, then it must be an acquaintance who committed the crime.

Zhao Yuan's living circle is very small, just in this area; the murderer is another three people.These two restrictive conditions provide very good conditions for the detection of the case.

3
The investigation department then divided into two groups. One group searched for thousands of people belonging to this area one by one, and the other group watched the only few public security camera probes in this area.

Soon, the case took a turn for the better.Investigators found images of three people walking together in the camera probe at the intersection of the area.Although the camera probe at this intersection could not reflect whether the three people entered the area from the outside or walked out from the area, the fact that the three people walked together naturally attracted the attention of the police.

The three men were seen on video surveillance at 07:30 on Tuesday night.This is a very sensitive time point. Since the murderer cut off the power of the surveillance video at 06:30 that night and started committing the crime, the entire crime process was almost completed at 07:30.

More importantly, the police quickly locked the two residents in this area through the vague clothing status and back figure of the three people.Yang Zhuang, 51, and Yang Tianqi, 23, are the father and son of the Yang family, and Zhao Kuang, 30, is the neighbor of the Yang family, the Zhao family.These three people are closely related, often going in and out together, doing nothing, eating, drinking, whoring and gambling.In particular, some people reported that these three people did not have formal jobs, and would do some casual work at nearby construction sites and hospitals to make ends meet.Because they are living in poverty, they often do some sneaky things. Although they have not been punished by the police and have no criminal record, their reputation is very bad.

However, Zhao Yuan and his wife, who have always been kind to others, are very kind to these three people.Zhao Dahua reflected that the bacon and sausage that Zhao Yuan made every year would often be given to the three of them.The most important clue is that these three people occasionally come to Zhao Yuan's house when Zhao Yuan is not busy, and play mahjong at Zhao Yuan's residence where the center site is located, and there is indeed an automatic mahjong machine in Zhao Yuan's residence.Zhao Dahua said that Zhao Yuan has no hobbies, but occasionally plays mahjong with his friends.Even if there is some gambling in nature, their chips are very small. It only costs one or two yuan to open a game of cards, and the win or loss in an afternoon of playing cards does not exceed [-]. Therefore, it is unlikely to be a dispute over gambling funds.

No matter what motives these three people had for the robbery, the three of them walked together, were very familiar with the deceased’s house, and occasionally entered and left the deceased’s house. Based on these three points, the police were enough to suspect them.

Fu Yuanman started to play the images of these three people passing the police camera probe on the big screen behind him.In the picture, the tall Zhao Kuang put his arms on Yang Tianqi's shoulders while walking, while Yang Zhuang kept his hands in his trouser pockets and walked with his head bowed.

"They shouldn't be the murderers." Ling Mo said to himself.

But Xiao Lang, who had super hearing, still heard it, and said loudly, "How do you know they are not murderers?"

"At 07:30, if the case is completed, and the walking gait is relaxed and normal, it does not conform to the point of view of criminal psychology." Ling Mo said.

"Maybe it's an act!" Xiao Lang said, "It's just a few seconds of video."

"That's why I said 'should' rather than 'certainly'." Ling Mo said, "The murderer is very likely to have blood on his body. At 07:30, it was just dark, and there was no reason to walk in a place full of acquaintances. Do not intentionally cover blood stains that may adhere to clothing."

Standing on the podium, Fu Yuanman didn't seem to hear what Ling Mo and Xiao Lang were talking about, and continued to introduce the case.

After obtaining this important information, the police took immediate action and brought under control the three people who were sleeping soundly at home on the night of the incident.After applying for a search warrant, on-site investigators searched the residences of the two families to which the three belonged.

Soon, the police found two Apple mobile phones and one Huawei mobile phone at Zhao Kuang's home. After inspection, they belonged to the victims Li Jiangjiang, Cheng Yuan and Feng Qi respectively.The police who searched Yang's house also found a gold necklace and a gold ring, which were identified as belonging to the victims Cheng Yuan and Fang Kexia respectively.

The police responsible for the on-site investigation were not satisfied with the discovery of important physical evidence. They continued to conduct a detailed search of the two houses and found a total of about 1 yuan in cash.On some banknotes, there seemed to be bright red blood stains.

The three people detained by the police complained one after another in three different interrogation rooms. They all said that they had not been to Zhao Yuan's house in the past few days, nor had they met Zhao Yuan, let alone murder.None of the three could provide an alibi for Tuesday afternoon.According to the three people, that afternoon, all three people were sleeping at home, and the three people could prove each other, and no one else could prove it.They slept until seven o'clock in the evening, and the three of them got up to meet for dinner, and then went to a small casino in the next town to try their luck. They played all night that night and won a lot of money.That's all, it's impossible to kill.

When the interrogation could not go on, the police showed three pieces of evidence to the three people.One is the above-mentioned mobile phones and gold and silver jewelry seized from their homes; the other is the RMB found in their homes, including [-] hundred-yuan bills and dozens of banknotes of other denominations, where the blood DNA of several victims was detected The third is the witness testimony provided by the police in charge of the peripheral investigation: In a night stall market not far from this area, several street stall owners said that the three people went to the stall to ask where Old mobile phones and gold and silver jewelry can be recycled.

It seems that the evidence is solid.

"See, the evidence is solid, and your psychological analysis is not working well." Xiao Lang said to Ling Mo with a playful smile.

Ling Mo shrugged his shoulders.

Under the iron evidence, the three still have new arguments.The three of them defended almost in unison. On the way to gamble, the three of them did pick up a black bag, which contained several mobile phones whose data had been emptied and SIM cards removed, gold and silver jewelry, and more than 6000 yuan in cash.At first they wanted to sell their mobile phones and jewelry, but after all, they had so much cash that they could squander it, so they went directly to the casino.After a night of gambling, 6000 yuan in cash turned into 1 yuan.So, the three of them shared the money and belongings, and each went home to sleep until the police came to the door.

Simply put, so much evidence was picked up by three people.

Of course, the police handling the case did not believe this "pie in the sky" statement, after all, there are so many unexplained reasons.For example, even if someone else committed the crime and dumped the stolen goods at the intersection and these three unlucky guys picked them up, then the three murderers who happened to enter the scene were also the three murderers?And the murderer tried his best to kill, rummage, and finally gave all the property to others?After investigation, the property found in the homes of these three people was basically all the property owned by the five people who were killed.

However, the prosecutor who intervened in advance and some police officers also raised doubts: the number of the three people and the number shown by the traces on the scene match up, and the three people did have stolen goods from the scene at home, but the three people defended with one voice It is indeed a reasonable doubt.After all, no evidence was found at the scene that could directly link the three of them. According to the spirit of the rule of law, there is indeed a lack of an important link in this chain of evidence.

Most policemen know that although there are many cases where everyone knows that the suspect is a criminal, it is precisely this "spirit of the rule of law" that allows these criminals to escape legal sanctions because of "no doubt".There is no way to do this, after all, the "rule of law" protects more innocent people who may be wronged, so the police can only find reasons from themselves and look for more conclusive evidence.

The items at the entire scene have been inspected many times, but no valuable and directional fingerprints and DNA were found.Especially the three pairs of slippers at the scene, and the tape that bound the five people repeatedly, from which the police failed to extract the DNA and fingerprints of the three people.The tape was surprisingly clean, only on the tape binding Zhao Yuan were a few fingerprints of Fang Kexia, which might have been printed when the two of them were in contact.

The three were detained in this way, then transferred to residential surveillance, detained again, and released again.Three years passed like this, and the police failed to find any more favorable evidence, and the three of them insisted that the stolen goods were picked up.After all, it was impossible to extract a confession by torture, and the three of them had enough time to form an offensive and defensive alliance, but the lack of evidence means insufficient evidence, and the case was dragged down.However, even if it was delayed, including the leader of the special case team, the director of the Bei'an City Public Security Bureau, and the experts from the provincial department, they all confirmed in their hearts that it was these three people who did it.The question now is how to find a breakthrough and make these three people bow their heads and plead guilty.

"Do you have any good ideas and ideas?" Fu Yuanman said dryly as he introduced the case. He drank his saliva and said.

"The situation at the scene is too complicated. I'm afraid it's hard to judge simply by looking at the photos." Ling Mo said.

"Yes yes yes, we are going to the scene, we are going to the scene." Xiao Lang echoed.

After Xiao Lang finished speaking, he whispered to Tang Dangdang beside him with a smirk on his face: "Let me tell you, the fish ball ramen in Bei'an City is really super delicious. I have always wanted to take you to eat it, and finally I have a chance gone."

"You still have the heart to eat!" Tang Dangdang said in surprise.

"How can you work if you're not full?" Xiao Lang said contentedly.

"It's not always necessary to go to the scene, team leader, can our big sand table simulate the scene?" Ling Mo said.

"Don't!" Xiao Lang shouted.

"Yes." Fu Yuanman nodded with a smile and said, "I have been preparing for a long time, and the on-site situation is entered into the system. Now I am building the on-site situation. It is estimated that you will be able to experience the scene in 10 minutes."

"Beian City is not far away! It's only three hours' drive!" Xiao Lang shouted.

No one paid any attention to him, everyone sorted out the materials one after another, and walked towards the big sand table, leaving Xiao Lang standing in the conference room swallowing his saliva.Fu Yuanman was the last to leave. He patted his grandson on the shoulder and said, "Because of this murder, the housing prices in the area at the scene have dropped sharply. Now it is a piece of rubble."

Wearing VR glasses, Ling Mo walked into the big sand table first.As in the photo, the sand table now presents a complex terrain with criss-cross alleys and densely packed houses.Although Ling Mo and Cheng Zimo's ability to recognize the terrain surpasses that of ordinary people, after entering this criss-crossing and extending in all directions, they also clearly know that it is meaningless to study the criminals' entrances and exits. As long as the murderer is familiar with the terrain, You can enter from any alley and exit from any alley.There are just a few police camera probes, and it is actually easy to avoid them.

"If it's so easy to dodge the camera probe, why didn't the three suspects who are familiar with the environment dodge?" Ling Mo thought to himself.

Everyone walked along the alley to the central scene, Zhao Yuan's home.

After entering the center site, everyone does different jobs.Nie Zhixuan was the first to walk to the side of the five corpses, quietly observing the state of the corpses; Cheng Zimo walked around the courtyard, looking for other entrances and exits; Tang Dangdang tried to fiddle with the leftover computer at the scene, but the computer data was not copied in. , so Tang Dangdang left first and went to Fu Yuanman to ask for the hard disk data; Xiao Lang was at the door observing the cut-off of the power supply of the light box while thinking about his fish ball ramen.

Ling Mo firmly memorized the patterns on the soles of the three pairs of slippers, and then studied the bloody footprints on the scene bit by bit.

Time passed by minute by minute, and more than three hours passed in the blink of an eye.Xiao Lang, who had nothing to do after researching the wires at the door, but was too embarrassed to disturb Tang Dangdang, was impatient: "I'm annoyed that you are so annoying."

"There is a reason for grinding." Nie Zhixuan patted Xiao Lang's shoulder with a smile, and said, "Now I have the same opinion as Ling Mo."

"Ling Mo? What's Ling Mo's opinion?" Xiao Lang asked, "Is there anything else that can be done in this case?"

"Didn't Ling Mo just say that the gait of the three people doesn't look like a suspect after committing the crime?" Nie Zhixuan said, "Now I also feel that there are many doubts in this case that do not support the three people being the murderer."

"Really?" Xiao Lang's eyes widened.

"Go, go to the meeting room, let's chat."

When we arrived at the venue, the case study did not start.According to Fu Yuanman, Ling Mo had to go to the night watchman organization laboratory to analyze the tape that bound the five people that was extracted from the scene.The tape at the scene bound the corpse tightly, like a mummy, so the forensic doctors could not untie the tape one by one. They had to cut the tape with scissors to avoid the knotted part of the tape, and then handed it to the laboratory as a whole.The police in the laboratory only extracted small pieces from different parts of the tape for DNA experiments, observed and looked for fingerprints as a whole, but did not destroy the order in which the tapes were bundled.After restoring the tape, we can still see how the murderer tied up the victim at that time.

After another three hours, Ling Mo walked into the venue after Xiao Lang was scratching his head after eating the instant noodles.Ling Mo said, "Let me ask, should I bind or kill first?"

"Tie it up first." Nie Zhixuan said, "The wound on the corpse coincided with the wound on the tape, so it was tied up before cutting."

"Before you said that the corpse had threat injuries[30] and resistance injuries[31], but they were all minor, right?" Ling Mo asked.

"Yes." Nie Zhixuan nodded.

"It sounds like you have discovered something?" Fu Yuanman asked with a smile on the podium.

"Indeed, team leader, this case is not easy." Nie Zhixuan said.

"Tell me about it." Fu Yuanman said.

"You say it, or should I say it?" Nie Zhixuan looked at Ling Mo with a begging look.

Ling Mo made a "please" gesture.

"Then let me talk about my doubts." Nie Zhixuan said, "My doubts started with the tape. This case gives us all the feeling that it is a robbery and murder case. This is because a murder case is different from a murder case. In a personal case, if you don’t come up with a murder, most likely there is a process of coercion, control, and forced confession of property. The five people at the scene were all tied up with tape, which seems to be a process of being coerced, but there is a logical problem.”

"What's the question?" Xiao Lang asked eagerly.

"At the scene, the neck was cut and there was a lot of bleeding, and the bloody shoe prints also showed that there was blood on the ground. The murderer stepped on it, and then went to search for belongings in various rooms. Then, since the murder was done first, and then the property was searched, why should What about controlling people?" Nie Zhixuan said, "Shouldn't it be to control people first, ask where the property is, then search, and finally kill?"

"Perhaps the murderer is confident in the forced confessions of these people?" Xiao Lang guessed.

"This is also a possibility." Nie Zhixuan said, "However, we have seen the tape at the scene, which firmly pasted the mouths of several people, so why did he force a confession?"

"This..." Xiao Lang pondered, "It seems to be true."

"This is indeed a suspicious point." Ling Mo said, "I studied the tape just now. I tied the mouth first, and then pulled the tape down to bind the hands, feet and body. The tape was not cut, but tied all the way to the end."

"That is to say, when controlling the victim, he just shut his mouth first." Xiao Lang said, "The tape is so strong that even the forensic doctor can't untie it, and it's obviously impossible to untie it before letting them speak."

"It looks like this tape is really superfluous." Cheng Zimo said, throwing a piece of chewing gum into his mouth.

"In addition, of the five victims, except for Zhao Yuan and his wife, whose mouth, hands and feet were only sealed with tape, the other three were covered with tape all over their bodies, like rice dumplings." Nie Zhixuan said, "The other three All the corpses showed signs of suffocation to varying degrees. In fact, a little common sense knows that if the mouth and nose are sealed with tape at the same time, they will suffocate to death. So, what is the use of him cutting their necks open?"

"Afraid that he will not die? Silence?" Xiao Lang said.

"We analyzed before that it was an acquaintance who committed the crime, but he was only familiar with Zhao Yuan and his wife, not the other three deceased!" Nie Zhixuan said, "It feels like venting anger."

"If it's a murder, and these five people have nothing to do with each other, there must be one or two people who are the real target of the murderer. The others are just strangers and innocent people. Why should we fear that they will not die?" Fu Yuanman Say.

"We'll talk about the real target later." Ling Mo said, "Only analyzing the order of the tapes can only be said to be a suspicious point. The murderer's act of making up the knife can be analyzed as venting anger, or it can be analyzed as camouflage."

"Pretending?" Xiao Lang put away his eager look, and began to think hard, "If there is a pretense, then this case will be in big trouble."

"The current basis, judging that there is a disguised behavior, is still hasty." Fu Yuanman said.

"Team leader, of course I have other reasons." Ling Mo was full of confidence.

4
Ling Mo stepped onto the podium, took the mouse from Fu Yuanman's hand, opened the drawing software on the computer, and drew a schematic diagram of the scene on the blank page.

"When we entered the scene, our first impression was that the scene was full of blood footprints, which was very messy. Moreover, even if we looked carefully, we concluded that all the 270 footprints came from the three pairs of slippers on the scene. And these three pairs of slippers have also been determined to belong to the family of the deceased Zhao Yuan." Ling Mo said, "It seems impossible to provide clues, but the clues are inside."

"270 one..." Xiao Lang said, "Didn't you write down all the locations?"

"Position is very important, but the direction of the toe is more important." Ling Mo said.

All members of the night watchmen, including Fu Yuanman and Tang Jun who had been sitting quietly in the back row without speaking, stared wide-eyed at this moment.Everyone knows that Ling Mo has a good memory, but to memorize the positions and orientations of nearly [-] shoe prints on the scene within three hours is simply not something a normal person can accomplish. of.

However, Ling Mo just remembered it.

"Because there are only three kinds of blood footprints at the scene, I used red, yellow and blue marks to distinguish the traces of the three pairs of slippers." Ling Mo first marked a red arrow on the picture, "The arrow is the tip of the shoe." The direction in which it is facing, that is, the direction in which the murderer is walking. Please give me a little time, and when I finish drawing, everyone will be able to see what is going on.”

Out of admiration for Ling Mo's "superpower", for the next half an hour or so, the venue was completely silent.Everyone sat silently in their seats, watching the big screen where arrows of different colors filled up the entire blank page one by one.

"260, 270, 270." Ling Mo breathed a sigh of relief and said, "After the painting is finished, can you see something?"

If it's just blood trails all over the scene, let alone just looking at the photos, it's impossible to draw any conclusions even after arriving at the scene.But after Ling Mo restores it in such a clear way, it seems that the direction of the blood footprint is clear.

"The red footprint started from the central scene and continued to Room 1, and then it broke, and there was no turning back. Instead, the yellow footprint entered Room 1 somehow, and walked out of Room 1 out of thin air. Come out." Xiao Lang's eyes are the sharpest, and his macroscopic control is also the strongest, so he was the first to discover the clues, "The situation in rooms 2, 3, 4, 5, and 6 is actually similar, and many of these footprints are from the No return' or 'no back and forth'! There are only a lot of intersections in the central scene and courtyard aisles. But if you look closely at these intersections, there is no complete walking route."

"That's right! That's what happened!" Ling Mo raised his eyebrows, and the scar on his face stretched a bit, "Besides, we can also see that there are at least two kinds of shoe prints in each room. , if these two kinds of shoe prints are one kind, it can explain the route of coming and going, but if they are separated, they cannot explain them.”

"What do you mean?" Although Tang Dangdang also saw this abnormal situation, he didn't realize the directionality of this clue.

"It means that there is only one perpetrator." Ling Mo concluded.

"One person?" Cheng Zimo was also a little surprised.

"Yes! One person!" Xiao Lang said, "This person is holding two pairs of slippers, wearing a pair of slippers, and walking around the site. He walked from the center site to Room 1. After messing around in Room 1, he changed into a pair of slippers, and Go to Room 2 to rummage. And so on. In addition to making many crosses of shoe prints in the center scene and in the courtyard corridor, the shoe prints in the room have exposed his behavior."

"Xiao Lang is right." Ling Mo said, "I had doubts at first because Brother Nie said that all five corpses had only superficial threatening injuries, and the resistance injuries were slight. Then since there was little resistance, why did the central scene The shoe prints are so complicated? This gave me the idea of ​​​​studying the direction of the footprints. I didn’t expect that the big secret was actually hidden in the footprints.”

"Why did the murderer go to such trouble?" Cheng Zimo asked.

"Pretending." Ling Mo said, "When we return to this word for the second time, we are basically close to the truth."

"A disguise?" Xiao Lang said, "This disguise is really complicated."

"Let me ask a question first." Cheng Zimo raised his hand and said, "Suppose the murderer disguised the scene, but how did the murderer know that the property he threw away happened to be picked up by three people? Obviously, the three suspects picked it up." It's stolen goods, and at this time, the murderer must have completed the crime process, otherwise where did the stolen goods come from?"

"This brings us back to the neck-cutting mentioned above." Ling Mo said, "If the murderer controls the person and leaves after cutting the neck, he can leave without any blood on his feet. All three pairs of shoes are stained with blood. Don’t you think it’s superfluous to have blood stains and walk around? So I think the neck cutting is to get blood to disguise.”

"You still haven't answered my question." Cheng Zimo repeated, "How did he know that three people would come to pick up the property? Did he know that these three people would pass by here that night? Even so, there is no guarantee that before that Somebody picked it up."

"No, the murderer killed people first, then took the property, then threw it at the designated location, and waited there." Ling Mo said, "When he saw three people picking up the property, he came back and stained three pairs of slippers with blood. To step on footprints."

"Actually, when he was really looking for things, there was no blood on his shoes?" Cheng Zimo asked.

"Even if there is a small amount of blood or mud, it is covered and hidden by a large number of bloody slippers." Nie Zhixuan said.

"Then how did the murderer know that these three people would definitely embezzle property?" Cheng Zimo continued to ask.

"I think it's a competitive mentality." Ling Mo said, "The murderer was observing in the dark. He analyzed that the three people would definitely embezzle property, so he thought of this way to plant the blame, and he escaped the punishment of the law. If he analyzed Thinking that the three people would definitely hand over their belongings to the police station, he had to think of other ways to avoid the crime. The reason why he removed the mobile phone card and erased the mobile phone data was to prevent the police from finding Zhao Yuan’s house quickly after the property was handed over. Because the murderer still needs time to go back and disguise the scene according to the actual situation."

"It makes sense." Cheng Zimo seemed to be convinced by Ling Mo.

"Now let's analyze the murderer's psychology." Ling Mo stood in the middle of the podium and said with great interest, "Since it is confirmed that he is pretending, then we can analyze his real intention. He pretended to be a money hunter." At the scene, he discarded all the property obtained at the scene, obviously, he was trying to find someone."

"But when I was waiting for you just now, I looked through the files at that time, and I didn't find any clues about the social contradictions of the several deceased." Xiao Lang said.

Ling Mo waved his hand at Xiao Lang, urging him not to interrupt, and continued: "It is also to use shoes stained with blood to fake footprints, since the murderer wants to wear slippers on purpose to leave traces, instead of using other shoes, sneakers, etc. To leave traces, his mentality of pretending to be a mature person to commit crimes is there, which just shows that he is not an acquaintance."

"But..." Xiao Lang couldn't hold back his impatience, and wanted to ask Ling Mo what was going on with the surveillance.After all, without acquaintances, it is impossible to be familiar with the monitoring line direction.In fact, Cheng Zimo also had doubts at this time, because she knew that if Zhao Yuan's neighbor, Zhao Dahua, was not at home on Tuesday, the murderer would not be able to commit the crime.The murderer has mastered Zhao Dahua's life rules, and it is difficult for anyone who is not an acquaintance to do so.However, affected by Ling Mo's high spirits, neither of them interrupted Ling Mo's train of thought.

"A stranger seeks someone, this is a very interesting proposition." Ling Mo said, "Since it's a stranger, it's certainly not so easy for the police to figure out the cause and effect relationship behind it. However, if we know the specific target of the murderer, say It is not possible to analyze anything. Therefore, I think the most important thing now is to know the real target of the murderer. After all, these five people belong to three different 'worlds', and they have nothing to do with each other except staying in the hotel. However , this is Brother Nie's strength."

"This is how I see it." Nie Zhixuan walked up to the podium, opened an overview photo of the scene, and said, "The situation at the scene is like this. Zhao Yuan and his wife were tied up with tape and lying on the ground. The curtains were pulled, causing The curtain rod fell from the top of the window, and the curtain rod was pressed against the couple's calves. The other three corpses were all lying on the top of the curtain rod, so I judged that the first to be controlled were Zhao Yuan and his wife. It also fits with why the central scene is in their residence."

"The order in which the remaining three people were tied up can be determined through the analysis of the tape." Ling Mo said, "I have carefully studied the fracture of the tape, and carried out the overall separation in the laboratory. Now it is certain that , Feng Qi was first bound with tape, then Cheng Yuan, and finally Li Jiangjiang."

"Everyone still remember that on the tape at the scene, only the tape binding Zhao Yuan had a few fingerprints of Fang Kexia." Nie Zhixuan reminded.

"Because the murderer is one person, they cannot be tied up at the same time. So the murderer controlled Fang Kexia and asked her to tie up Zhao Yuan, and then the murderer tied up Fang Kexia." Ling Mo said, "At this time, Feng Qi, Cheng Yuan, Li Jiang Jiang may have returned from the outside and was controlled one by one. I believe this is also unexpected by the murderer."

"Well, according to the record, these tenants usually come back after serving the patients to sleep between nine o'clock and ten o'clock." Xiao Lang flipped through the file and said, "This should also be why the murderer chose this day just after dark. , the reason for committing the crime when there were few people. But I didn’t expect that people came back one by one, and the murderer had to be tied up and killed one by one.”

"If the murderer is not an acquaintance, and the target is only Zhao Yuan and his wife, why kill them all?" Cheng Zimo said, "Anyway, they don't know the murderer, so how can they talk about it?"

"Did you see that the murderer wrapped his head with tape so much that he suffocated all three of them. I'm afraid he regretted trying to untie the tape and couldn't do it?" Xiao Lang said, "And he has already I decided to disguise the scene as robbery, so if someone is alive, wouldn't his next actions reveal his true intentions?"

"Xiao Lang is right." Ling Mo said, "Let's go back to the original question, binding Zhao Yuan and his wife is a normal binding action, but the binding of the latter three is obviously 'passed', and they are all wrapped into rice dumplings. According to the previous analysis, it can be easily concluded that the target of the murderer is Zhao Yuan and his wife. The reason why the latter three people were wrapped in tape more seriously is because their sudden appearance terrified the murderer. This kind of restraint of the victim The behavior of excessive binding at the end just reminded the murderer of panic. People came back one by one, making the murderer terrified again and again. After killing Zhao Yuan and his wife, I put the blame on other tenants, but I didn't expect that the other tenants came back early, so I have no choice but to find someone who is ignorant of the money and put the blame on."

"That is to say, the next step is to continue to investigate Zhao Yuan's social conflicts?" Tang Jun finally began to speak in the back row, and this time the interrogative sentence made his tone no longer that of a teacher, but a colleague who was discussing things .Tang Jun knew that the talent of this 20-year-old kid in front of him had far surpassed his own, and he made unremitting efforts to train him, and today he really started to shine.

"Teacher, I think investigating Zhao Yuan's social contradictions is only one of the ways." Ling Mo said, "After all, the crime was committed by a stranger, and there are many factors such as hired murderer, passion murder, abnormal personality murder, etc., and these factors may all be involved. It is difficult to find out through the investigation of contradictory relationships."

"Then tell me, what are your other options?" Tang Jun nodded with satisfaction.

"As a lesson from the past, we still have to find a way to extract the DNA of the murderer from the scene. Whether it is for solving the case, or for future prosecution and trial, this clue must not be let go. After all, we now have a clue about the case. With a new understanding, we have a new judgment on the reconstruction of the scene, and there are more ways to extract DNA.” Ling Mo said, “In addition, so many of our previous judgments point to the fact that the murderer is a stranger. When I said just now , Xiao Lang and Zimo both have doubts. I know, you want to say, if you are a stranger, how do you know the activities of your neighbor Zhao Dahua? There is only one answer that can explain this question, that is, stepping on the spot. Through the detailed stepping on the spot in the early stage, the murderer made it clear that there were few black people at this time, which was the best time to commit the crime. It was clear that Zhao Dahua was not at home every Tuesday, and that the deceased There is monitoring at home, and the monitored electricity access is a series of information at the light box, and then a crime plan is made to carry out the crime. We are now going to make a fuss from stepping on the spot."

"I don't mind anything else, but the surveillance doesn't make sense." Xiao Lang shook his head like a rattle, "Although the surveillance has been cut off, all the video records left by the murderer's previous visits are still in the computer. Since the murderer knew There is monitoring, why not remove the computer? If you think the goal of removing the computer is too big, you can also destroy the computer. It is impossible for this well-planned murderer to forget about it?"

"This is indeed a question." Ling Mo lowered his head and said, "Actually, the monitoring is only a power outage, not to destroy the previous records. Apart from the first possibility, it is because the acquaintances do not need to check the location and leave no images. There is another possibility. One possibility is that the murderer didn't care that the surveillance left his image."

"Why don't you care?" Xiao Lang asked.

silence.

After a long time, Ling Mo broke the silence: "In addition to the surveillance of Zhao Yuan's family, we also have several police surveillance. With so many images superimposed, whether we can find the suspect's trace depends on you and Dangdang."

"Me?" Cheng Zimo asked in surprise.

"You told me about your intuition." Ling Mo smiled slightly, "I trust your intuition."
