Chapter 64 Clues on the Skin
In fact, generally speaking, when the murderer peels off such a large piece of skin, the convenience of wearing gloves is obviously not as good as not wearing gloves.
Furthermore, judging from the marks and thickness of the skin cuts, the other party is obviously not good at knife skills.
Not like a good cook, nor like a doctor with a scalpel.
The possibility of not wearing gloves is relatively high.
In addition, after the murderer finished embalming the skin, he still had to paint. During this process, the possibility of wearing gloves was even smaller.
What Lu Chuan is doing now is to separate the transparent resin from the skin.
This is the reverse thinking of collecting fingerprints on the skin.
Collecting fingerprints on the skin is not done directly on the skin, but through a certain method to imprint the fingerprints on the skin.
From this point of view, Lu Chuan was a little lucky.
Because the transparent resin material on the skin can play this role.
What Lu Chuan needs to do now is to separate the resin material from the skin, and then look for fingerprints on the inner layer where the resin material contacts the skin.
This is a very meticulous job.
The resin itself is very sticky. After bonding to the skin, it is difficult to separate due to the rough texture of the skin.
Fortunately, the skin has been soaked in formalin in advance, which has a certain lubricating effect.
Although it is very slow to process, at least it will not cause serious damage to the skin.
Yang Sen and Lao Bai are currently in front of the computer, preprocessing the fingerprints collected by Lu Chuan on the picture frame.
“Most of these fingerprints have scratch marks and can no longer be used.”
The biggest fear of fingerprints is friction marks.
This is just like when we slide the unlock button on the phone screen.
The finger slides over a long distance, and although fingerprints can be left, there are long drag marks.
Only on the outer edge of the first position where the finger landed, there was a slightly clearer fingerprint.
Yang Sen very much recognized Lao Bai's judgment: "It took more than two hours for me to process three fingerprints, and all of them failed to compare."
The action team has already collected the fingerprints. Collected fingerprints of all exhibition hall staff.
The porters and installers of the paintings were also among them.
In other words, these people will definitely leave fingerprints on the frame.
But now the comparison still fails, which means that Yang Sen's preprocessing of fingerprints has failed.
Actually, Liu Guodong did not let Yang Sen and Lao Bai take over these fingerprints.
The two of them just had nothing to do and wanted to give it a try.
The result of trying it is that I am indeed older.
I have the heart, but I don’t have the strength.
Just like not men of any age group are suitable to go to Tongguan Road.
Ten:28pm.
The separation of resin pigments and skin is finally over.
Looking at a whole piece of human skin in front of him and a piece of transparent resin covering the human skin, Lu Chuan let out a long sigh.
The murderer must be a pervert.
During the separation process, Lu Chuan felt this way more and more.
Shen Yanliu frowned on the side. After two years of working as a forensic doctor, this was the first time she encountered such a crazy and terrifying case.
Although in the past, when dissecting corpses, the skin of the deceased would be touched, and even when cleaning the internal organs and cutting the skull, some skin would be rolled away.
But that is the need of the workflow, not just a human skin in front of you now.
This reminded Shen Yan of a movie she had seen before, Painted Skin.
To be honest, the horror seen on TV is not on the same level as this.
"I will collect the fingerprints on this layer of resin paint next. If I can succeed, I can basically identify that it was left by the murderer."
There is no problem with this inference. of.
The skin has been formalin treated before painting.
During this process, if fingerprints can be extracted from the skin, they must belong to the murderer. Unless the murderer was processing fingerprints, the deceased's skin had been intimately touched by others.
"The skin will be handed over to you next."
Although it is no longer possible to determine the cause of death through the skin, Shen Yan still has to do some toxicology tests as usual.
Don’t underestimate these processes.
In many murder cases, the cause of death of the body cannot be discovered at a glance.
Although suffocation and injury with sharp objects are common, there are also many murder cases where the cause of death cannot be seen from the appearance of the corpse.
This is also the fundamental reason for dissection.
Of course, from the perspective of forensic medicine, there are roughly two purposes of dissection.
The first is to find out how the body died.
The second is to find out who the body is.
Of course, under normal circumstances, neither is needed.
Carefully rolling up the skin, Lu Chuan continued: "When I was separating the resin, I just discovered that there are half-centimeter long scars under the deceased's breasts. The deceased may have had breast augmentation surgery."
"I have reported this situation, and Team Leader Sun and Team Leader Ren should have started investigating."
Currently, because the identity of the deceased has not been determined, anyone who can guide the discovery of the identity of the deceased is welcome Information must be taken seriously.
Breast augmentation surgery is obviously not a minor surgery.
Whether the other party is in a hospital or another beauty institution, identity records may be left behind.
Shen Yan nodded, took the skin, and returned to the forensic laboratory.
Over there, Wang Changjiang’s plane has landed and he rushed back overnight.
Early the next morning.
Everyone in the action group 1 and 2 ran out.
With no new clues in the exhibition hall, all efforts were focused on the clue that the deceased had breast enlargement.
Last night, the forensic doctor conducted further examination of the skin and basically determined some basic information about the deceased.
Female, judging from the tightness and color of the skin, the deceased was between twenty and forty years old.
He is 1.66 meters tall and weighs about 50 kilograms.
The time of death should be within one month.
The cause of death has not been found yet.
Because the back part of the human skin is missing, there is no obvious trauma on the front part, and there is no toxic reaction.
In addition, there were no stretch marks on the skin of the deceased's abdomen, so he should have never given birth.
So, the current clue is the wound at the bottom of the deceased's breasts, which may have been a scar left by breast augmentation.
Of course, this is just a guess.
It is also possible that the deceased had suffered from some disease, such as the removal of powdery tumors, the removal of breast hyperplasia, or other diseases, and it is possible that scars were left at this location.
Wang Shuai, an investigator in the action group, has been in the police for thirteen years and is the backbone of the criminal investigation detachment.
For this investigation, he was in charge of Tianmei International Plastic Surgery Hospital.
These days, all plastic surgery hospitals seem to be able to connect with international standards.
Just like the little baby on Tongguan Road, if you ask her how long she has been doing it, she will always do it two or three times.
Never the first time, never hundreds of times.
Anyway, if you don’t ask, they won’t tell.
As you asked, it was two or three times. The family was in urgent need of money, and they left when they had earned enough.
But she will be there next week, and she will be there next month.
The family is always short of money.
After looking at the plaque on the door and the endless stream of young ladies pursuing truth, goodness and beauty, Wang Shuai walked in.
