Chapter 18 Who is she (3)
Xiao Wu's idea was not to find another forensic doctor to do an autopsy, because even if the best forensic doctor in the country was invited to do an autopsy, it might be possible to make a more accurate judgment on the cause and time of death, but it would not necessarily help to determine the identity of the deceased.

Xiao Wu was inspired by Lao Cui. He thought that since he didn't know hallux valgus, the forensic doctor might miss some clues.Is it possible to go back to "traces"?Collect clues to the identity of the deceased from the traces left on the corpse.

"There is no forensic medicine department, but we have autopsy classes and professors who teach forensic medicine. It is unlikely to invite professors to come. I want to invite teachers and students from the school's criminal science and technology department to study together. Come to judge the identity. It’s definitely no problem to invite them to come. Anyway, they also need on-site practice opportunities.”

The "criminal science and technology" that Xiao Wu talked about is actually a basic technology that public security forensic doctors and technicians should master.In teaching, many of the learning subjects of the Department of Criminal Science and Technology and the Department of Forensic Medicine overlap.Due to the higher and higher requirements for the basic theoretical knowledge of forensic medicine, the forensic medicine department of the police academy does not recruit undergraduates.The two best police schools in China, Public Security University and Criminal Police Academy, only recruit graduate students or second degrees for medical school graduates.However, forensic science is a compulsory subject for undergraduates studying criminal science and technology in the police academy, and autopsy is also indispensable.

When students in the Department of Criminal Science and Technology went to the public security organs and various identification centers for internships in their senior years, they also worked for forensic doctors or did physical evidence identification.Anyway, the students need to practice, so if Xiao Wu wants to invite them, it will be no problem.

"Okay, then try it, a dead horse is a living horse doctor." Old Cui originally wanted to say that you really thought that the cobbler could beat Zhuge Liang.Whether it is forensic autopsy or trace analysis, it is a profession that is very particular about experience.Old Cui is not optimistic about these rookies.But seeing that Xiao Wu is so active, I am embarrassed to strike again.

Xiao Wu encouraged himself and Lao Cui: "There are many people and strength is great. Maybe the juniors and juniors will have new discoveries." Sunshine is positive, energetic, and constantly pops up new ideas.Looking at Xiao Wu, Old Cui seemed to think of his youth.

Alas, old Cui, cheer up!Old Cui also secretly encouraged himself from the bottom of his heart.

Things went smoothly as Xiao Wu judged.The Criminal Science and Technology Department of the Public Security University sent a graduating class and two leading teachers.One of the teachers is an associate professor of forensic science.A total of more than 30 people surrounded a dissecting table with three layers inside and outside.Xiao Wu only glanced at the corpse, then dodged behind them.Lao Cui is responsible for introducing the situation.

Originally, Xiao Wu and Lao Cui discussed whether to not provide the existing autopsy report and let the students find the answer by themselves, so that it would not be easy to be restrained.Lao Cui believes that the students do not have enough experience after all, so there is no need to waste time, and it is better to present the existing reports for everyone to discuss.

So Lao Cui first stated the existing autopsy report and pointed out some key points to the teacher and classmates one by one.At the same time, it is stated that the existing autopsy report can be questioned, but there must be conclusive evidence to explain the reasons for the inconsistency.Lao Cui clearly pointed out that the most important purpose of inviting everyone to this trip is to restore the identity of the deceased through technical analysis.

"I hope that through everyone's careful inspection and analysis, tell us what kind of person she is? How can we find her?"

The entire autopsy process lasted all day.In the morning, the associate professor of forensic science was responsible for the operation and explanation.According to the autopsy report, up and down, front and back, inside and outside, various corpse spots, scars and signs of corruption were found, identified, observed, recorded and photographed one by one.Students ask questions and teachers explain, which is completely an on-site teaching class.

Old Cui felt a little boring, but Xiao Wu became more and more energetic as he listened, and slowly squeezed to the front to observe.After all, if you want to be a good criminal policeman, how can you be afraid of corpses?

Xiao Wu paid special attention to the deceased's feet. The outer sides of the thumbs of both feet of the deceased were deformed, with an obvious protrusion.The other four toes were also squeezed and curled up, and the toes were slightly turned up.Callouses on the soles of the feet and scuffs on the heels.It's certainly not genetics, a victim of high heels.

Hallux valgus in real life is uglier than the photos, Xiao Wu thought, he must advise his girlfriend to wear less high heels in the future.

When explaining the characteristics of the deceased's drug use, Lao Cui asked the associate professor to check whether there were injection marks on the deceased's arm?The result was indeed as Zhao Zhuowen pointed out. No injection needles could be found on the deceased's arm, including the upper body, and there were no obvious signs of drug invasion in the veins of the upper arm.

In contrast, there were obvious scars, bruises and needle holes left by drug injection in the groin of the deceased, and the adjacent veins were also blue-purple and hardened, which should be caused by heroin injection.The associate professor pointed to a scar on the groin and said: "From this dent, the deceased had injected drugs for at least one year. But there were no traces of injection on the arms and body. This kind of injection habit is rare." Careful again After observation, the associate professor pointed out that there were two kinds of needle holes in the groin of the deceased: one was a long time ago, and the color of the needle holes was black;There are a lot of old needle eyes, there are about dozens of them on both sides.Only two new pinholes were found, on the right thigh.Since the part of the groin near the genitals has been eaten by maggots, there may be new needle holes in the eaten part, so it is not known yet.Old Cui asked: "Can you tell when the old needle eye and the new needle eye occurred?" The associate professor looked at it carefully for a while, and said to Lao Cui: "The old needle eye should be three months ago, and the two new needle eyes It should have been within a few days before her death. From the analysis of these two needles, she should have not injected drugs for a long time. These scars look quite clean, not as dirty and festering as some drug addicts .I think I should go to detoxification. I haven’t smoked for a while, and I have been treated for purulent infection. I may have relapsed recently. If I haven’t smoked for a long time and suddenly relapsed, if the dose is not well controlled, particularly prone to sudden death."

The associate professor asked the students: "Later, you can take samples of the blood and hair separately to test the type and content of drugs. The hair should be tested in sections, so that we can roughly grasp the time and amount of drug use. If she did quit drugs some time ago , then the drug content in the two or three centimeters of hair near the scalp should be reduced to zero."

When Lao Cui and Zhao Zhuowen discussed before, although Zhao Zhuowen did not mention the old and new needles, he was not as "dirty and sick" to the deceased as ordinary drug addicts. Zhao Zhuowen's opinion was consistent with that of the associate professor. The inflammation should be relieved and treated.

Old Cui basically agrees with the forensic doctor's point of view, but he still has his own views.Due to the persecution of drugs on human immunity and the transmission of diseases by sharing needles, drug users are often unable to avoid the invasion of various bacterial diseases, so they suffer from various inflammations, suppuration, ulceration and other diseases on the body surface.Old Cui just snorted, and felt that his health was getting worse and worse, and he was prone to colds, fevers, and fatigue.The body of the deceased appeared to be quite "clean", which may be related to her environment, economic situation, attention to personal hygiene, and the quality of heroin used.The deceased should have paid more attention to hygiene during his lifetime, and did not share injection needles with others, so there was no cross-infection.Therefore, the body surface is relatively clean, without the common suppuration and ulcers of drug addicts, and there are no more diseases in the body except tuberculosis.Therefore, Lao Cui speculated that the deceased might be considered a "respectable" person like him.Moreover, she is likely to be a person with a job who needs to be in constant contact with others and pays more attention to her personal image.Heroin is injected on the back of the hand and arm, and the needle hole is easily seen by outsiders.In order to avoid being suspected of being a drug addict, she chose to hide her groin when injecting drugs.

At the same time, taking into account the high cost of drug use and drug rehabilitation, Lao Cui concluded that the deceased was probably a person with a high personal income or a good family background.

In the afternoon, after the associate professor finished the forensic science class, the senior students of the Department of Criminal Science and Technology started to do their own work.They work together in a division of labor and take what they need.From head to toe, from outside to inside, almost all parts and organs of the female corpse were photographed and sampled.

By the time the thirty students collected everything they needed, the female corpse was already riddled with holes.For example, the original long hair with a shawl is now a scab.Part of the finger was cut off before, and now the nails have also been pulled out.It's a bit shocking!

Lao Cui thought to himself that these people were the real "Old Destroyers". Should I withdraw the body donation book?However, one group of students specifically repositioned the muscles and skin that had been turned over in the face.What is this for?Xiao Wu proudly said to Old Cui: "This is what I asked for. I asked them to restore the face of the deceased." "Is that okay?" "It's nothing wrong. At that time, they will position according to the remaining facial features and then draw a portrait. Try to see if you can restore the face of the dead, hehe, a dead horse is a living horse doctor, it’s better to try than to do nothing.”

... When work was over at night, Xiao Wu shouted: "Students, I hope you will not embarrass the Public Security University. Whether this big case can be solved depends on you! Students, do you have confidence?" "Yes!"

Old Cui smiled at the side. He felt that Xiao Wu was persistent, hard-working, and thoughtful, and he would be a good criminal policeman in the future.

6. Rookie Discovery
Contrary to Lao Cui's expectation, the senior rookie invited by Xiao Wu soon made a major discovery.In the facial samples of the female corpse they brought back, a small fragment of the prosthesis used for rhinoplasty was found.At first, the students regarded it as nasal cartilage, but later discovered its tissue structure under a microscope, which was not a biological body. After research, they thought it was artificially added rhinoplasty material prosthesis.Moreover, this prosthesis is not a commonly used silicone prosthesis, but a relatively expensive expanded body.

"Do you know what bulging is? Old Cui." Old Cui shook his head, he really didn't know what "bulging" was. "Well, I'm here to teach you." Xiao Wu was very proud.The junior and junior sisters are doing well, and they didn't discredit their alma mater.

"Women have plastic surgery, rhinoplasty, and raising their noses, that is, putting a small plastic piece of prosthesis into the nose. Expanded body is a kind of prosthesis, and its scientific name is polytetrafluoroethylene."

In fact, Xiao Wu didn't even know what a puffy body was before his junior informed him of the important discovery?The following information comes from his search on the Internet:

The scientific name of expanded body is polytetrafluoroethylene.The inert PTFE is expanded to produce a microporous structure.Due to its good biocompatibility and unique microporous structure, it is non-toxic, non-carcinogenic, and has no side effects such as sensitization, and human tissue cells and blood vessels can grow into its micropores to form tissue connections, just like autologous tissue.From a medical point of view, it is currently the most ideal biological tissue substitute.

"The deceased should have undergone rhinoplasty before his death. The bulge is very soft. It should be that the murderer chopped it up with a knife when he was disfigured." Xiao Wu gestured with his fingers to cut the nose horizontally and vertically.

"I've already contacted the funeral home. The students will go to the autopsy in the afternoon to see if they can find the remaining bulging fragments."

"Then it's better to check carefully to see if she has had other plastic surgery?" "Okay, I will explain to them." Old Cui asked Xiao Wu: "How much does a rhinoplasty cost now? You How much does the augmentation cost?" "Expansion is a relatively advanced material for rhinoplasty, and there is another cheap material called silica gel. The price difference between the two is several times. I saw on the Internet that silicone implant augmentation One-time nasal materials plus surgery costs four to five thousand for cheap, and expensive for eight to nine thousand. Rhinoplasty usually costs tens of thousands. This is what I have learned initially. The online price is very messy. You need to ask the plastic surgery hospital for the specific price. .”

Old Cui thought, this bloated body was indeed a major discovery, and Zhao Zhuowen and the others neglected it during the autopsy.The deceased had undergone plastic surgery before his death, which confirmed Lao Cui's guess: the deceased should be a rich man.

Xiao Wu disapproved: "Why does the whole appearance look like a rich man? Now it's too common for women to have plastic surgery. When I was in middle school, some female classmates cut their double eyelids. A nose augmentation can cost thousands or tens of thousands of dollars. Save money on food and expenses. You can save money. Many girls go for plastic surgery when they are in college, in order to find a job after graduation, or marry a good husband. Plastic surgery does not waste time during holidays, and many parents support it. The money from the family is considered an investment .”

Old Cui said unhurriedly: "You are right, the cost of plastic surgery is one-time, you can save enough money to go for surgery. But do you know how much these white powder suckers spend every day?"

"Teacher Cui, I know." Xiao Wu has taken anti-drug classes and knows that drug use is a high consumption, especially in a big city like Beijing.

The price of one gram of heroin of unknown purity in Beijing ranges from 2000 to 1 yuan.Addicts have at least two to three grams per day, and more than five grams.If the deceased smoked two grams of heroin a day, then the daily cost of drugs would be at least four to five hundred yuan. Not counting other expenses every month, the purchase of drugs alone would cost at least [-] yuan.

After being addicted to drugs, he has no intention of working, and later develops to run out of wealth and poverty, and often commits crimes for a little drug money.

Lao Cui believed that the deceased was more "decent" and should be able to afford drug use financially.And "decent people" often get above-average prices for drugs, which requires her to be more financially well off.Generally, No. 4 heroin costs more than [-] yuan per gram, two grams per day, and at least [-] yuan per month.

Xiao Wu said: "[-] per month, including food and clothing, is about [-]. [-] is not very high!" Old Cui almost choked on the smoke: "[-] is not much a month? How much do you earn a month?" Xiao Wu said with a smile, "How can you compare with me? How many rich people are there in Beijing now? Any farmer here is richer than me." Xiao Wu is still in the internship period, and every day The monthly salary and subsidies add up to less than [-]. "Maybe I used to have money, but now I'm running out of money, and finally I'll take a big shot and commit suicide."

"The possibility of suicide is relatively small."

"why?"

"If you want to commit suicide, you don't need to go to drug rehab. She should have been rehabilitated before, unlike the person who wants to die. If it is not compulsory drug rehab, going to a private drug rehab center may cost more than taking drugs. And people who smoke drugs are generally not Suicide, 'skating' has a higher suicide rate."

"Why?" Xiao Wu was curious. "White powder is so beautiful when you inhale it, you feel like you are in heaven, life is so beautiful, how can you be willing to die? Just think about how to make money before inhaling."

"What about meth?"

"Inhalation of methamphetamine is hyperactivity. Afterwards, anxiety, depression, hallucinations, easy to get depression, and some people will commit suicide."

"Wow, old Cui, have you smoked before, so you understand?"

"I've never eaten pork, but I've seen pigs run away!"

"Try it anytime, what's it like? I heard that it's hard to smoke white powder for the first time. As long as you don't smoke, you won't be addicted."

"Don't, curiosity killed the cat. Drugs should never be touched. How can you not be addicted once? That is a lie. The first time you smoke heroin, it is uncomfortable. Many people will faint and vomit, but after that I feel very relaxed and comfortable. Then there will be a second, third time, and then I will be addicted. After the addiction, people will be useless. Don’t touch it! You know?”

Old Cui has tried both white powder and methamphetamine.From a criminal policeman to an anti-narcotics policeman, Lao Cui is also full of self-confidence. He thinks that he has strong willpower.A lesson from the past, Lao Cui does not want Xiao Wu to repeat his mistakes.

"According to what you said, if the deceased was a rich man, then the scope of the search can be narrowed down a lot. With a monthly expenditure of [-], then she must live in a good place." Xiao Wu turned on the computer, and the Drug addicts called out.Those whose registered addresses seem to live in relatively high-end areas have been found, identified, and excluded. On the contrary, many of those who appear to be in poor economic conditions have not been found.

Now I'm going to have another headache.What if the deceased is nowhere to be found?
Maybe after the alumni figure out her plastic surgery program, they can check it out at the plastic surgery hospital.
