Female Forensic Bone Collector

Chapter 8 Appearance Restoration

Chapter 8 Appearance Restoration

At this moment, the laboratory staff next door sent the blood test report they urgently needed. Zhang Tong took off his gloves and took a look. The report showed that the carbon monoxide content in 1 ml of blood concentration was only [-]%. It means that the possibility of dying from the smoke can be completely ruled out.

"It seems that the possibility of the deceased committing suicide is very high! Xiao Deng, do you still remember what we saw when we first entered the scene?"

Deng Ran nodded: "The corpse is lying prone facing the sofa, and its limbs are only slightly curled up, unlike ordinary fire accident victims whose limbs are basically bent at [-] degrees."

"That proves my inference! Let's see if there are other signs on the surface of the corpse."

Since the fire burned away the hair and scalp of the deceased, when observing the head of the deceased, the wound on the back of the head was clearly visible, very deep, and even bones could be seen!It's just strange that the wound has no signs of healing, on the contrary it is very fresh and there are no scabs!Due to the contraction of the surrounding muscles, the opening appeared very large, about one centimeter wide!The wound was vertical. According to the approximate height ratio of the deceased, the height of the wound must be between 1.7m1.8 and [-]m. In this way, it completely conforms to the height ratio of an adult man!

When inspecting the deceased's knee, Zhang Tong found a scar. Although the skin on the surface of the deceased was completely burned, the scar that reached deep into the internal muscles was not so easily overlooked.There were also significant bruises on the deceased's neck and back.The depth of the bruises shows how much strength was used to cause the injuries!The most important thing is that these scars have never been formed for more than 24 hours!

"Zhang Forensic Doctor, what should we do next?"

"Notify the serious crime team, this is obviously a murder!"

"So, how did these bruises form?" Deng Ran asked curiously, "I feel very unusual!"

Zhang Tong nodded: "Do you still remember where we saw the dead bodies when we first entered the scene?"

"Yes, prone!"

"On the whole, I speculate that the situation at that time may be like this: the two sides scuffled and injured the back of the deceased's head and knees. In the end, the murderer pressed his knees on the deceased's back, and then tightly grabbed the deceased's throat with both hands until he died, and then set fire to it. Destroy corpses and wipe out traces!"

"This bastard! It's too cruel." Deng Ran muttered angrily.

"Don't be dazed, call now!" Zhang Tong turned the corpse over, then picked up the scalpel, and began to scratch from under the clavicle of the deceased's left shoulder to the second rib in the chest, and then , and make the same incision from the clavicle of the right shoulder, the two places meet at one point, which forms a V-shape, and then extends downward from the apex to the finger-width below the belly button of the deceased, and finally, When the chest opener was pushed to both sides, the chest and abdomen of the deceased were all presented in front of her.Although the deceased was found in the fire scene, and his appearance was completely deformed by the burning, there was no trace of black in the chest and abdominal cavity of the deceased, but severe atrophy caused by the lack of water in the tissues.This further confirmed her inference that the deceased was cremated after death from another angle.

The next thing to do is to write the autopsy report.In the column of cause of death, Zhang Tong filled in "death of mechanical suffocation caused by external force" stroke by stroke, which is completely different from the previously expected conclusion of "fire accident".

"Forensic doctor Zhang, with your report, it seems that the guys in the serious crime team have to work overtime again tonight!"

As soon as I arrived at the unit early the next morning, I was notified to attend the case analysis meeting.When Zhang Tong hurried to the conference room on the second floor, the room was already full of people.Many people stayed up late last night, their eyes were bloodshot, and the air was filled with the unpleasant smell of smoke.Although there are repeated orders in the society that smoking is not allowed in public places, in the Tianchang City Public Security Bureau, this regulation has no effect at all, because the leaders know that many of these front-line police officers have to rely on a cigarette to refresh themselves.If you smoke a lot, three packs a day is still less!

The person who reported the situation was Lao Zheng, the deputy head of the trace inspection team. In order to allow everyone to more intuitively combine the evidence they obtained with the situation provided by the forensic doctor, he started with the forensic doctor's injury report.

"The vertical wound on the back of the deceased's head is exactly the same as the wound caused by the ashtray found at the scene. When we first found the ashtray, it was empty, with a lot of cigarette butts on the side. The coffee table was obviously emptied, and we successfully extracted fingerprints on it. We also found some corresponding tiny human blood and tissues in the gaps in the ashtray!"

As he said that, he showed everyone three enlarged photos, which were the ashtray, the wound of the deceased, and a comparison of the wounds caused by the two.Then, he showed a photo of the almost burned sofa at the scene, and a large piece of burned and damaged floor in front of the sofa.

"We studied the damaged form on the floor in front of the sofa. Obviously, the fire gradually spread to the middle of the room. The floor was sprayed with a liquid catalyst, which formed an unusual way of burning. We found it in a trash can in the corner of the scene. An empty white wine bottle, and no trace of saliva was found on the mouth of the bottle. It is very likely that this is the catalyst, because we cannot find traces of the catalyst in the combustion residue, and the alcohol will evaporate when exposed to high temperature. Also Yes," Lao Zheng then showed a close-up photo of the wall behind the sofa, the big V-shaped flame baked, shocking, "This pattern tells us that the sofa is the point of fire!"

"Can I ask a question?" Someone raised a hand, "Why didn't the fire spread?"

Old Zheng nodded: "The combustion needs oxygen in the air to support the combustion, but this room is airtight, so the flame will go out after burning for a while!"

Speaking of this, Lao Zheng paused for a moment, with serious eyes: "Our trace inspection conclusion is also that this case is a murder case, and the murderer has a certain knowledge of firefighting! He knows how to start a fire and how to spread it! If it weren't for him If the room is closed too tightly, when we find out, a lot of evidence may be destroyed by the fire!"

"Forensic doctor Zhang, can you confirm the identity of the deceased?" Li Ju, who is in charge of criminal investigation, turned to look at Zhang Tong on the other side.

"The deceased was female. Based on the size of the pelvis, the growth stage of the teeth and the age of the deceased's bones, I can only roughly determine the age range as between 25 and 30 years old. There are still three relatively complete fingers, and I extracted the fingerprints using the saline perfusion method, and I have entered the specific information into the computer for preservation, and I also have attached notes in this report."

"What about the identity of the owner?"

Criminal police captain Wang Yanan said: "The owner of the house at the scene of the fire is a 70-year-old man named Qin. He said that the house was rented to a girl from Henan, named Lu Xiaoxi, two months ago. The age on the ID card is 28 years old, and he works as a cashier in a supermarket in the city. He doesn't know anything else. I have sent someone to the supermarket and will retrieve her personal items as soon as possible to see if fingerprints can be extracted for future use. Comparison."

Director Li nodded: "There is nothing else? Then, let's stop here today and report the situation as soon as possible! Your serious crime team must carefully follow up on Lu Xiaoxi's situation!"

"Ok!"

Two days later, Wang Yanan invited Zhang Tong to the cafe.

"Tell me, Xiaotong, why do people nowadays do everything for the sake of feelings?"

Zhang Tong was stunned: "What do you mean by that?"

"Of course I'm referring to Lu Xiaoxi, the deceased in the arson case. The one that was broken just now, I really can't figure it out! You said, for the sake of feelings, this kind of invisible and intangible thing, I would rather take my own life, alas... I don't Will ruin my life because of feelings!" Wang Yanan sighed heavily, "There are too few good men now!"

Zhang Tong couldn't help but secretly smiled bitterly.That Lu Xiaoxi fell in love with the company's married man, and pestered him endlessly, forcing him to divorce and marry her. As a result, that man became murderous.She died terribly. That night, after some tenderness, he knocked her unconscious with an ashtray while he wasn't there.He then straddled her and strangled her with both hands.Afterwards, he grabbed the wine bottle at the corner of the table, poured all the wine on her body and set it on fire in an attempt to destroy the body and wipe out the traces.

"Forensic doctor Zhang, a child with a suspicious cause of death has been sent to the hospital. The serious case team has been notified. You should prepare for an autopsy as soon as possible! The body has been parked in the autopsy room."

"I'll be there right away!" After hanging up the phone, Zhang Tong immediately put down his pen, reached out and rubbed the sore corners of his eyes, then stood up and walked to the dressing room next to the office.

The corpse under the white sheet on the dissection table looked very thin, it was a child!Seeing this scene, Zhang Tong couldn't help but let out a long sigh: "Xiao Deng, hurry up and get ready, we'll start working right away!"

The doctor who accompanied the ambulance to escort the corpse was the doctor who reported the case. She was very young, she looked like she had just graduated from medical school, and there was some melancholy between her brows.She was standing at the door signing the handover document.

"Hello, I'm Zhang Forensic Doctor." Zhang Tong greeted, "Are you from the emergency room of the Second Hospital?"

She nodded and said nothing more.

"When was the child sent to your hospital?" Zhang Tong asked Xiao Deng for important clues while motioning for Xiao Deng to help her put on a leather apron.

"An hour ago, that is, around [-]:[-]. When the child was delivered, there was no obvious breathing and heartbeat! The parents said that the child was playful and fell down accidentally, but I found that the child had a Many inexplicable scars, bruises all over the body, and the child's cervical vertebrae have obviously been broken due to external force, so I suspect that she died abnormally, and she was beaten many times before she was alive, and she was severely malnourished. At the hospital, I have I informed the security department and the hospital leaders, and they will try their best to keep the child's parents and tell them about the child's death. My colleagues from the police station accompanied me here, and the rest is up to you." , she raised her head, and handed the big manila envelope she had been holding to Zhang Tong, "This is all her related cases, not many, I have tried my best."

"Don't worry! How about you go back first and I will notify you as soon as I have news?"

"No, I'll wait outside the dissecting room." After saying this, the female doctor in the emergency room nodded to Zhang Tong, glanced at the dissecting table, and then turned and walked out.Such a scene seemed very weird. The handover between two doctors was just that one was facing a dead person while the other was facing a living person.

The atmosphere in the dissecting room suddenly became tense, and the cameraman Lao Zhang was fiddling with his instruments without saying a word.Although he does not have to do the autopsy himself, and he is not a forensic doctor, according to the regulations, he must truthfully record every scene of the forensic doctor performing the autopsy. On the one hand, it is for supervision, and on the other hand, it is also convenient. evidence.

Lying on the cold dissecting table was a two-year-old girl, extremely thin, and her small naked body was covered with various scars, shocking people.After a person dies, because the blood stops flowing, all the bruises caused by external forces suffered during his lifetime are now fully visible. The deep ones are traumas that have been formed for a relatively long time, while the relatively shallow ones are caused by trauma that has been formed for a relatively long time. Within 24 hours.Counting carefully, there are as many as 45 traumas on this little girl's body!The most worrisome thing was the two latest scars on the upper and outer sides of the deceased's two arms. Zhang Tong compared them with both hands. It was obvious that an adult had tightly grasped her two arms!The force is so deep that the two thumb prints are clearly visible!

The child's hair was thin and yellow, and a few strands were pulled out with a light tug. It can be seen that the child must have not received careful care for a long time, and the diet is poor!From the signs of skin and bones all over her body, it can already be concluded that the deceased was severely malnourished and could not eat enough for a long time!
X-rays showed that the deceased's arm had been fractured many times due to external forces, as had his leg bones.Seeing such disturbing evidence, Zhang Tong couldn't help but take a deep breath. It seems that the deceased not only didn't have enough to eat, but also suffered inhuman abuse!According to the case provided by the hospital, she quickly found evidence of a fracture in the cervical spine of the deceased, which was caused by an external force. Once the spinal cord inside the cervical spine loses the protection of the cervical spine, it will be damaged at the same time. Breathing and movement stop.Based on the obvious bruises on the two arms of the deceased, she immediately pieced together a scene that made her hair stand on end: an adult firmly grasped the two young arms of the deceased, and then lifted her into the air, violently Shaking back and forth, finally, causing the cervical spine to break and die!

However, Zhang Tong soon discovered a deep hole about one centimeter long in the back of the head on the right side of the deceased.After carefully shaving off the dead man's hair, he found that the skull at the edge of the wound showed radial cracks. Obviously, the wound was formed by violent external force and multiple impacts. substance!
Without raising his head, Zhang Tong said to the assistant Deng Ran standing beside him: "Little Deng, please ask the doctor in the emergency room at the door, when the deceased was brought in, was the clothes on his body stained with blood? A lot of blood !"

Deng Ran nodded and went out. Soon, he ran back: "She said no, it was very clean, and there was no blood on the clothes!"

Zhang Tong suddenly felt his heart beating faster: "Hurry up and notify the serious crime team, the parents of the deceased are lying! This is an obvious case of child abuse injury and death!"

Wang Yanan quickly took over the case.She took the technicians of the trace identification team to the rental house of the deceased's parents in the east of Tianchang City. The colleagues of the trace identification team found several holes in the wall with obvious blood stains, and the wall ash samples were also related to the deceased The remnants of the head wound fit perfectly.In the trash can in the corner of the house, there was a set of children's clothes that were almost blood-stained. After preliminary inspection, the blood stains on it were exactly the same as those of the deceased.

The child's parents were taken to the criminal police immediately.

In the interrogation room, the child's mother seemed flustered, and she kept secretly scanning the investigators in front of her.No one spoke, and the room was silent.

After a long time, the emaciated middle-aged woman finally let out a long sigh.

"She shouldn't have come to this world!"

"She's your daughter! How could you do it?" Wang Yan, who was also a young mother, who was in charge of the interrogation, couldn't help asking angrily, "Tiger poison doesn't eat children, let alone you are human!"

"I... I am also in trouble!" As she spoke, her tears flowed down silently.

It turned out that the couple came from a remote village in northern Shaanxi. They already had two daughters in their hometown, one is five years old and the other is three years old.However, in order to have a son to "carry on the family line", they ignored the relevant regulations on family planning and secretly conceived a third child while working in Tianchang City.Unexpectedly, God made another joke with them. The third child was still a girl, that is, the deceased.From then on, this weak life was doomed to an unfortunate end.

In order to work and earn money, the young couple had no choice but to send their third daughter back to their hometown in northern Shaanxi.However, less than a year later, news came from my hometown that the person in charge of family planning in the town was coming to investigate the child's origin. In desperation, the child's grandmother sent the little girl back. Parents who work in Tianchang City.However, the couple had no time to take care of their children. The most important point was that the third child was not the boy they had longed for. Therefore, beside the parents who were in a bad mood, this innocent child was often beaten for trivial things. scolded.The two-year-old child doesn't understand anything, and he can't even eat enough!During the day, he was locked in the house with a big lock, and he was not allowed to come out at night.The cause of the tragedy this time was just because the child was too hungry and wanted to find something to eat, but accidentally broke the thermos bottle at home.After returning home and seeing the mess all over the place, the mother who lost her mind for a moment grabbed her emaciated daughter, shook her vigorously, and cursed. Due to too much force, she not only hit the wall, but also knocked her daughter's underdeveloped body. The cervical spine was shaken and broken!By the time the child's father found out about this scene and wanted to stop it, the child was already out of breath.

After writing the autopsy report, Zhang Tong raised his head and found Wang Yanan standing beside him with a melancholy expression: "Yanan, when did you come?"

"I've been here for a long time. Seeing that you are busy, I dare not speak."

"Are you in a bad mood? For that child?" Zhang Tong put down the pen in his hand.

"The human heart is full of meat, that child is so pitiful! I have been a criminal police officer for so many years, and as long as the case in my hand involves a child, I feel uncomfortable!"

"Me too. Cough...forget it, the case is closed, why don't you go back? It's so late, I'm going to get off work!" Zhang Tong stood up, and at the same time began to tidy up a table scattered on the workbench paper.

"It's okay," Wang Yanan shrugged indifferently, putting his hands in his trouser pockets, "I'm alone anyway, with nothing to worry about, it doesn't matter if I go home early or late, let's go together!"

The flower base on the outskirts of Tianchang City has to clean up the mixed flower fertilizer stored in the open air every two months.Today is the fixed day to clean up the flower and fertilizer, so the work team entered the site early in the morning.Looking at the pile of flower manure, the captain frowned, turned around and yelled: "Brothers, work hard! There are so many, if you take a long time, you can't finish it until dark today!"

"Okay!" A few of his staff moved the ladder skillfully, put it on the pile of mixed flower fertilizer, and then carried the shovel and climbed up with hands and feet.

"Don't try to be lazy! Be quick!" the captain yelled loudly, walking towards the delivery truck parked beside the flower and compost heap.It didn't take long for the high piles of flower fertilizer to be stirred evenly, and slowly transported along the long chute into the back bucket of the truck.

Time passed by, and when it was almost noon, the manure pile was much shorter.Suddenly, a worker screamed and swayed, almost slipping off the flower and fertilizer pile more than two meters above the ground.

Seeing this, the workers around him rushed forward and grabbed him.The captain also heard the terrifying scream, he frowned and walked closer: "What's wrong?"

Several workers remained motionless, looking at the compost pile beside them with ashen faces.

The captain realized the strangeness of the situation and climbed up the ladder.When he came to the working platform, he was about to mutter a few words of complaint, but before he could speak, the things in the manure pile in front of him made his words choke in his mouth.His first reaction was that his stomach was overwhelmed, and before he had time to digest the noodles he ate in the morning, he vomited them all up.

After a while, the captain came back to his senses.He wanted to climb down the ladder, but his feet were weak, and the workers around him didn't look good.He had no choice but to grit his teeth, took out his mobile phone with trembling hands, and dialed 110.

When Zhang Tong received a call from the bureau, he was about to leave for work when his mother called, chattering, "I said, Tong Tong, why are you so ignorant? The person your uncle introduced to you is so ignorant. Why? Just say that you are a forensic doctor who deals with the dead every day, can you not frighten people? He is a very good young man! It is really hard to find even with a lantern."

"Mom, I'm a forensic doctor, I can't lie to others!" Zhang Tong impatiently perfunctory his mother, "Okay, okay, next time we have a blind date, I don't say anything, I have to leave quickly. The bureau urged me !"

"Hi!" The mother sighed on the phone, "You are the only one busy! If you continue like this, you will be an old girl for the rest of your life, no one wants you. Silly girl!"

"Mom, just forgive me. Don't forget to take your medicine on time! I'm off to work, bye!" After speaking, Zhang Tong hung up the phone.

When they arrived at the scene, Wang Yanan had already arrived with the serious crime team. About 50 meters away from the scene, the eye-catching police isolation belt had surrounded the mixed flower and compost heap where the body was found.Outside the isolation zone, several workers in overalls of the base had already gathered, their eyes full of fear and anxiety.

After showing his ID, Zhang Tong walked into the isolation zone with his assistant Deng Ran.The flower and fertilizer pile in front of me is 5 square meters wide and about two meters high. Next to it are several workers' shovels and a small truck for transporting flower and fertilizer.There are five ladders on the surface of the mixed flower fertilizer pile. Climbing up the ladders to the working surface, I saw that the flower fertilizer had been shoveled away, exuding a stench. The most surface appeared to be a thing similar to a human chest cavity, and underneath was a A group of fabrics that cannot distinguish the color and shape.Zhang Tong put on gloves, squatted down in front of the flower and compost pile, and while motioning for Deng Ran to take a close-up photo, he reached into the compost pile to search further.They had to find as many relevant human skeletons as possible, not just a simple chest analog, before they could conclude that it was a homicide.

Since this is a pile of compost, one can imagine how rich the contents are.It didn't take long to find some animal remains and some human garbage. Although the weather was not very hot, the smell of manure still made everyone dizzy.The two forensic doctors Zhang Tong and Deng Ran put on masks and carefully searched for things that resembled human remains one by one.The tall manure pile was not completely smoothed until the sun was about to set, and a complete skeleton had been laid out on the black plastic sheet beside the manure pile, and there was still a small amount of muscle tissue on the skull of the deceased.Finally, Zhang Tong stood up with difficulty and took off his gloves and mask. Due to squatting for a long time, his legs were almost completely numb.

"Yanan, it should be finished."

"How long has this corpse been buried here, can you give an approximate time frame now?"

Zhang Tong shook his head, and while arranging the bones, he replied, "It is still inconclusive, because this is a pile of mixed flower fertilizer, and its chemical reaction process will have a great impact on human corpses, and can even accelerate the decomposition of corpses! The degree of decay is unbelievable, I need to do further testing to get an approximate time frame, but it is very difficult! I will report to you as soon as possible after I go back to the autopsy!"

"That is to say, it is very difficult to determine the exact time of death of the deceased?" Wang Yanan said solemnly.

"Yes, the murderer threw the corpse here just to confuse us with the degree of fermentation of the compost. He is very smart!" Zhang Tong looked down at the shape of the deceased's pelvis and skull, "Judging by the age of the bones, this is A woman in her mid-thirties who has given birth. That's all I can tell you right now."

"Then, let's meet at the bureau and give me the autopsy report as soon as possible!"

Zhang Tong nodded, and then directed his assistant Deng Ran to help sort out the bones and prepare to bring them back to the bureau for an immediate autopsy.

The corpse in front of him is one of the more headache cases among the corpses that Zhang Tong has examined.She frowned, looked at the dissecting table in front of her, and knew in her heart that the hair or muscle tissue DNA extraction and testing methods most commonly used by forensic doctors would not work here at all, because the hateful mixed fertilizer would corrode all the useful external information of the corpse , polluted.For the rest, even the amount required to make a specimen cannot be extracted, let alone important information such as judging the identity of the deceased.The murderer obviously knew the characteristics of the mixed fertilizer very well. The corpse on the dissecting table in front of him had already changed beyond recognition, and he was completely helpless in determining its correct death time!When the various components in the mixed fertilizer undergo chemical reactions, they will generate a lot of heat, which will speed up the decay of the corpse!Under normal conditions, the time for a corpse to decompose and decompose depends on the surrounding environment and temperature, about one month on average.However, if the corpse is buried in this mixed compost heap, it will have such an effect in less than a week, not to mention that there are countless various bacteria in the compost heap, and the corpse will rot faster !
There are still two methods before us, one is to extract the teeth of the deceased.Fortunately, the deceased's teeth were very neat and intact, and the fertilizer did not affect the enamel on the outside of the teeth. However, in China, due to the lack of attention to the protection of teeth, there are no relevant dental records to check.However, the interior of human teeth is hollow, and the pulp contains the complete DNA tissue information of the deceased.After cleaning the skull, Zhang Tong removed a complete molar of the deceased, polished it, and then used a needle to extract the pulp tissue.Everything is going smooth.This is of great help in confirming the identity of the deceased in the future.

Next, facing the sparsely polluted muscle tissue on the carrion, she chose a method that others could not accept to obtain a clean and complete skeleton.After she patiently explained the steps to be carried out, Deng Ran's face became elongated: "Zhang Fayi, no way, this is too terrifying!"

Zhang Tong smiled slightly and said, "No way, you go and prepare! Now we can only do this, let's get over it!"

Deng Ran reluctantly walked out of the house. When he reached the door, he turned around and said awkwardly, "Zhang Fayi, what should I say to the people in the warehouse? Are you telling the truth?"

Zhang Tong quickly shook his head: "Fool, if you say that, the two of us will become freaks in the eyes of others! Let's say it is for experimentation!"

Deng Ran nodded helplessly.

Not long after, the young man brought an induction cooker and a large pot.When the cameraman saw this scene, although he was also at a loss, he still stepped forward to help.Soon, the special stove was set up and the water started to boil. Zhang Tong added an enzyme cleaner to the water.After the water boiled, she signaled Deng Ran to do it together, and the two carefully put the rotting corpses on the dissecting table down into the pot one by one.This situation is really like "stewing ribs" in a big pot in the cafeteria!The difference is that what they put into the pot are human bones!Not long after, the small dissecting room was filled with a strange smell and an indescribable fishy smell.

In fact, there is a reason why many forensic doctors do this, because if there is no way to determine the identity of a corpse, and there is no corresponding DNA database for comparison, the only method is to extract the skeleton.In this way, facial reconstruction can be carried out. As early as the early 20s, William?Krogman was the first to use it.In layman's terms, after the bone age and sex have been determined, the facial features of the deceased are reconstructed from the skull using clay, which is based partly on careful measurements and partly on the imagination of the reconstructor.Now, unlike before, these jobs can be identified and reconstructed by computer scanning, which is much more accurate than human hands!Although without the testimony of other people, the forensic doctor is still unable to determine the fatness and thinness of the deceased, but a general appearance can still be determined, which will be of great help in finding the source of the corpse!The second point is that sometimes, human bones can faithfully record the fatal injuries suffered by the deceased, such as fractures, and even small cracks on the bones can be of great help in deducing the cause of death of the deceased!In the face of rotting corpses, if you want to get a complete skeleton as soon as possible, the method of boiling in high temperature water is the best, and the sterilization is efficient, but the process is inevitably unacceptable to people's psychology.

Long-time boiling at high temperature made the weird smell in the air of the dissecting room more and more intense, but it was much better than the smell of mixed fertilizer.Time passed by every minute, and finally, the flesh and blood were separated.Under Zhang Tong's demonstration, Deng Ran and her carefully fished out each bone with a large iron spoon, and put them back on the dissecting table.At this moment, compared with the unrecognizable rotting corpse just now, even though it was still that corpse, it looked much more pleasing to the eye. After the stove was turned off, there was no smell in the air.Under the direct light above the dissecting table, the bones were blindingly white.The two carefully inspected the corpse's head and feet one by one, not letting go of every small crack. Finally, they found an obvious crack in the hyoid bone at the lower part of the skull. The rest of the body has no obvious cracks that could lead to death.

"Xiao Deng, it is very likely that the deceased was strangled to death, because the hyoid bone belongs to the bottom of the cranial cavity. Generally speaking, it will not be injured unless the hyoid bone is broken by squeezing the deceased's neck with both hands. He suffocated to death!" Zhang Tong pointed out to Deng Ran who was standing opposite her the only damaged part of the deceased's skull, and performed a motion simulation in the air.

"However, we still have to rule out other causes of death. It's just a pity that the deceased's body was contaminated by mixed fertilizers, and there is no way to make further inferences." At this point, she held the skull of the deceased with both hands, " Xiao Deng, turn on the computer and the laser scanner, and next, we will perform craniofacial imaging and reconstruction on the deceased!"

Hearing this, Deng Ran was a little excited, because he rarely had the opportunity to get in touch with technical practice in this area.While he was busy, he said excitedly: "Zhang Fayi, can I operate it later?"

"Of course, it's very simple. It's similar to playing computer graphics!" She said, and placed the dead man's skull on the tripod under the scanner, and then adjusted the angle. Then, she signaled to Deng Ran Get started.With the buzzing sound of the instrument running, a beam of red light slowly swept across the entire skull. After repeating this three times from different angles, the instrument issued a "beep" sound, indicating that the scanning was over, and the rest of the work had to be done by a dedicated computer software to complete.

"Xiao Deng, you enter 'female' in the column of gender, '30 years old' in the column of age, 'already educated' in the column of marriage and childbearing, and 'Asian' in the column of race." Zhang Tong Station Behind Deng Ran, he pointed carefully by category.It turns out that the corresponding data of women of various age groups are stored in the computer database, which comes from the second-generation ID photo data repository of the public security system. The data collection is quite complete, and it has a data set for each age group of women. The corresponding average value, combined with the data collected according to the laser scanning, will soon have a rough facial restoration result.

While waiting for the face restoration image to be made and printed, using this time, Zhang Tong, Deng Ran, and the videographer raised the cauldron that was still steaming, and poured the water into the dissecting table The stainless steel filter on the other side, so that some muscle tissue and hair of the deceased can be left behind, and the remaining waste water will be properly treated in the special sewer under the dissection room before being discharged into the waste ditch.At this time, a lifelike simulated portrait of a human face spit out from the printer connected to the computer behind him.

"Zhang Forensic Doctor, what about this pot?"

"Keep it, it can be used again next time!" She replied casually.

Hearing this, Deng Ran swallowed in distress and stopped talking.

In order to further test whether there is any evidence directly related to this case in the pile of compost where the corpse was buried, the trace identification team, which is only one wall away from the forensic office, actually moved the entire compost pile back.At the moment, their laboratory is full of a smelly and smoky smell unique to compost, but these very patient boys are meticulously sifting through every inch of compost with a small sieve. Do everything possible.As they found more and more "trophies", the expressions on the boys' faces became more serious.Soon, the table was covered with large and small bottles and cans, and there were all kinds of disposable sealed bags for evidence, which contained rags, suspected spectacle frames, watches... In the next time, they It is necessary to screen and test these "treasures" that have been found with great difficulty one by one. Many relevant information of the deceased may be inside.

In the serious crime team office, Wang Yanan was carefully studying the topographic map near the flower base, when his assistant Wang Yan opened the door and walked in.

"Team Wang, there is good news. Soon after the simulated portrait was released on TV, someone called and recognized the deceased——Zhao Youmei, a female employee of an electronics factory called Yuanxing near the flower base! It is said that she After leaving work, no one has seen her again!"

"Okay!" Upon hearing this, Wang Yanan immediately got excited, "Notify the people in the trace identification team, and immediately go to the electronics factory to extract the DNA of the deceased and come back for comparison!"

Just as Wang Yan was about to turn around and go out, she was stopped by Wang Yanan again: "Wait, tell Awang to come to me immediately!"

Awang is Wang Yanan's right-hand man in the serious crime team. The two have been partners for nearly ten years. They are tall and tall, but they have a heart of Buddha.

"Captain Wang, are you looking for me?"

"Yes, immediately call a group of people, let's go to Yuanxing Electronics Factory together! The source of the corpse has been found!"

Comparing the hair DNA sample extracted from the wooden comb that the deceased left in the factory locker tool box with the DNA sample from the decayed tooth pulp, the results showed that the two were exactly the same!The mass of rags under the corpse found in the compost heap could not distinguish its original color. After identification, it was the factory uniform of the deceased.So far, it can be confirmed that the deceased is Zhao Youmei, a female electronics factory worker who has been missing for a week.

Wang Yanan was a little worried. The suspect was very familiar with the characteristics of mixed fertilizers, so he should consider the two locations together. If he could find someone who had contacts on both sides, it would be easy to handle, no matter what kind of connection it was.Wang Yanan and a group of young men under his command spent almost every day in the flower base and the electronics factory, investigating one by one. Not long after, an unintentional rumor gave a clear clue to the case.Through interviews with colleagues around the female worker, we got news that this female worker often complained to the surrounding workers that someone pestered her and even threatened her.Although this person has never shown her face in public, every time she talked about this matter, she would say a word in her mouth, which attracted the attention of colleagues in the serious crime team——the person who pestered her had a very serious Fertilizer smell.

Three days later, Wang Yanan returned to the bureau with his investigation team. At the same time as their car, there was also an assistant engineer in the new product development department of the flower base who was in his 40s and looked depressed.

In the corridor on the ground floor, Zhang Tong ran into Wang Yanan who just came back.She couldn't help but stopped, and quietly called to Wang Yan who was walking at the end of the line. Before Zhang Tong could speak, Wang Yan nodded.The meaning is very clear, without conclusive evidence, they will not bring this person back alone.

In the interrogation room, Liu Ziru lowered his head and said nothing.

"Do you know what true love is?" Wang Yanan's sudden words stunned everyone present.

Liu Ziru slowly raised his head with a confused look on his face.

"Do you think there is love between you and Zhao Youmei?" Wang Yanan asked again.

Liu Ziru suddenly jumped up as if being pricked by a needle, and screamed: "You are not allowed to insult the relationship between me and Amei! There is true love between us! We love each other!"

"Sit down! Do you hear me!" Wang Yanan scolded angrily, "You said you loved her, so why did you kill her!"

"I...I..." Liu Ziru was speechless for a moment, he regained his previous daze, and muttered to himself, "I love her, I really love her! She doesn't understand me! I ……I do not know what to do!……"

Seeing this scene, Wang Yanan knew that the suspect's solid psychological defense had been defeated.She nodded slightly to Wang Yan beside her, signaling that the interrogation could continue now.

Liu Ziru, an introverted assistant engineer, has never found the person he likes because he only deals with flowers.By chance, he met Zhao Youmei whose husband was working in other places.Maybe it's because the heart longing for love has been suppressed for too long. He fell madly in love with Zhao Youmei who was married, but Zhao Youmei refused repeatedly and made sarcastic remarks, which caused the paranoid Liu Ziru to strangle Zhao Youmei to death on the way to get off work. Pull the corpse to the flower base with a small cart, and bury the corpse in the flower compost heap.The suspect knew very well that the heap of mixed flower compost would pile up higher and higher. In a few days, the body of the deceased would be decomposed by the fertilizer and bacteria without anyone noticing it. People will connect it beyond recognition with the missing female worker.However, he had calculated thousands of times, but he didn't count that he had stumbled on the forensic and trace identification.It really echoes the old saying - if you want others to not know, you must do nothing yourself!

Every time a case is solved, Zhang Tong always feels relieved.After writing the last word of the autopsy report, she took a deep breath, leaned on the office chair and stretched her muscles. "Xiao Tong, when do you get off work?" Wang Yanan walked into the office without knocking on the door, and sat down on the desk in front of Zhang Tong.

"Leave immediately!" Zhang Tong smiled.

As a forensic doctor, Zhang Tong knew that he had no right to choose a case.However, forensic medicine is also a human being, and when human beings have fear and fear.She stood blankly on the edge of the Populus euphratica forest, looking at the endless golden yellow in front of her, but her feet seemed to be filled with lead, and she couldn't take a step forward.

"Forensic Zhang, are you okay? Are you feeling unwell?" Pan Jian, who had just returned from his internship, kindly reminded him.

"It's nothing, I didn't rest well last night, let's do something." Having said that, Zhang Tong's face was pale.She gritted her teeth, and continued to walk towards the scene in the woods not far away, which was tightly surrounded by red and blue warning tapes.

"Look, forensic doctor Zhang, reporter Zhao arrived earlier than us today!" Following the direction of Pan Jian's finger, Zhang Tong saw Zhao Junjie who had disappeared for nearly a week.

"What is he doing here?"

Just as he was talking, Zhao Junjie had already seen Zhang Tong, and he immediately greeted him nervously.

"Forensic Zhang, why did you take over this case? It shouldn't be yours!"

"Old Zheng is on a business trip, of course I'm the only one to pick it up. What's wrong? Can't I pick it up?"

Zhao Junjie laughed awkwardly: "That's not true, you misunderstood me. The corpse is over there, Team Wang has been waiting for you for a long time!"

Zhang Tong didn't talk to him any more, and walked forward faster.

"Yanan, what's the matter?"

Wang Yanan pointed to a shallow pit on the right side: "Someone took a dog out for a trip, and the dog picked up some bones here. The dog owner felt that the bones did not look like ordinary animal bones, so he called the police."

Zhang Tong squatted down beside the shallow pit, carefully inspecting the bones scattered in the pit, and remained silent for a long time.

"What's wrong? Is the situation serious?"

Zhang Tong suddenly understood the reason why Zhao Junjie was so nervous about herself: a small leg bone was lying quietly in her hand, judging from the closed state of the bone seam, the owner of this leg bone would not Over 12 years old!

As time passed, more and more bones were found on the white plastic sheeting on the ground, and finally, also found at the bottom of the shallow pit, was a small intact human skull.

Zhang Tong stared at the two dark eye sockets on the skull, as if time had stopped.

"Forensic Zhang?" Pan Jian reminded in a low voice, "What should we do next?"

Zhang Tong didn't say anything, he just felt dizzy, his mind went blank, and he had a splitting headache.

Pan Jian looked around in embarrassment: "Forensic Zhang? What's wrong with you? Everyone is looking at us!"

"I'm fine, let's deal with it quickly! Put all these bones away." As he spoke, Zhang Tong suppressed the grief in his heart, got up and walked to the forensic on-site car parked not far away.

Seeing this scene, Wang Yanan couldn't help being a little stunned. Her good friend Zhang Tong obviously looked a little bit wrong, which was completely different from her rigorous style when she appeared on the scene in the past.

"Xiao Pan, what happened to your boss today?"

"I don't know," Pan Jian spread his hands, "She feels uncomfortable when she arrives here today. I think it's because she didn't sleep well last night."

"Really?" Wang Yanan would never believe that Zhang Tong did this because he didn't have a good rest. She knew her too well.

"Hey, brother, do you know? Something happened to Populus euphratica today!" As soon as Zhao Junjie left the scene, he couldn't wait to call Liu Chunxiao who was still working in the procuratorate.

"Pullar euphratica?"

"Yes, it's the Populus euphratica where Zhang's forensic sister had an accident 20 years ago. I rushed over as soon as I got the news today."

"What about the case?"

"I heard from the serious crime team that it is the remains of a child, and it looks old."

"Did Zhang Tong take over this case?"

"Yes. I didn't expect her to take this case either."

After hanging up the phone, Liu Chunxiao looked serious. Could it really be Zhang Qiu who disappeared 20 years ago?
