In fact, generally speaking, when a murderer peels off such a large area of skin, the convenience of wearing gloves is obviously not as good as not wearing gloves.
Moreover, judging from the cut marks and thickness of the skin, it was obvious that the other party was not good at knife skills.
He doesn't look like a good cook, nor does he look 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 detailed job.
The resin itself has strong viscosity. 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 beforehand, 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 cannot be used anymore."
What fingerprints are most afraid of are friction marks.
It's like sliding 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 collected fingerprints from all exhibition hall staff.
The movers 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 failed.
In fact, 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 men of any age group are not suitable for going to Tongguan Road.
10:28 p.m.
The separation of resin pigments and skin is finally over.
Looking at a whole piece of human skin and a piece of transparent resin covering the human skin in front of him, 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 Yan 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.
"Next, I will collect the fingerprints on this layer of resin paint. If I can succeed, I can basically identify that it was left by the murderer."
This inference is unproblematic.
The skin has been treated with formalin 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.
"Then the skin will be left to you."
Although the cause of death could no longer be determined through the skin, Shen Yan still had 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 injuries 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.
One 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 were half-centimeter long scars under the deceased's breasts. The deceased may have had breast augmentation surgery."
"I have already reported this situation, and Team Leader Sun and Team Leader Ren should have started investigating."
At present, because the identity of the deceased has not been determined, any information that can lead to the discovery of the identity of the deceased must be taken seriously.
Breast augmentation surgery is obviously not a minor surgery.
Regardless of 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 had landed and he rushed back overnight.
Early the next morning.
Everyone in the action group 1 and 2 ran out.
In the absence of new clues from the exhibition hall, all efforts were focused on the clue that the deceased had enlarged breasts.
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 20 and 40 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 or toxic reaction to the front part.
In addition, there were no stretch marks on the skin of the deceased's abdomen, so he should have never given birth.
Therefore, 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 acne, such as 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 13 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.
You asked, that is, two or three times. The family is in urgent need of money, and they will leave when they have earned enough.
But she's there next week, and she's 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.
