Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 64 Clues on the skin
In fact, generally speaking, the convenience of wearing gloves for the murderer to peel off such a large piece of skin is obviously not as good as not wearing gloves.

Moreover, judging from the traces and thickness of the cut skin, 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 large.

In addition, the murderer had to paint after embalming the skin, and 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.

The collection of fingerprints on the skin is not carried out directly on the skin, but through certain methods to rub 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 in the inner layer where the resin material contacts the skin.

This is a very meticulous job.

The resin itself is very viscous, and after bonding with the skin, it is not easy 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 deal with, 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 frame.

"Most of these fingerprints have been scratched and can't be used."

Fingerprints are most afraid of friction marks.

It's like we swipe the unlock button on the phone screen.

There is a long-distance swipe of the finger, although it can also leave fingerprints, but there are longer drag marks.

Only the outer edge of the first position where the finger landed has a slightly clearer fingerprint.

Yang Sen recognized Lao Bai's judgment very much: "It took more than two hours before I processed three fingerprints, and all of them failed to compare."

The action team has collected the fingerprints of all the exhibition hall staff.

The porters and exhibition workers of the paintings are also among them.

That said, these people are sure to leave fingerprints on the frame.

But the comparison still failed, which means that Yang Sen's preprocessing of the fingerprints failed.

In fact, Liu Guodong did not let Yang Sen and Lao Bai take over these fingerprints.

The two of them just have nothing to do and want to try.

The result of the test is that the age is indeed old.

With that heart, without that strength.

Just like not men of any age group are suitable to go to Tongguan Road.

28:[-] p.m.

The separation work of resin pigment and skin is finally over.

Looking at the whole piece of human skin and a piece of transparent resin covering the human skin in front of him, Lu Chuan heaved a long sigh.

The killer must be a pervert.

During the separation process, Lu Chuan felt this feeling more and more.

Shen Yanliu on the side frowned. She had been a forensic doctor for two years, and this was the first time she encountered such a crazy and terrifying case.

Although in the past, when dissecting a corpse, the skin of the deceased would be touched, and some skin would be rolled up when the internal organs were cleaned and the skull was cut.

But that is the need of the workflow, not just a human skin in front of him now.

This reminded Shen Yan of a movie she had seen before, Painted Skin.

To be honest, the level of horror seen on TV is not at the same level as this one.

"Next, I will collect the fingerprints on this layer of resin paint. If it succeeds, it can basically be determined that it was left by the murderer."

This inference is unquestionable.

The skin has been treated with formalin before painting.

During this process, if fingerprints can be extracted from the skin, it must belong to the murderer.

Unless the murderer was dealing with fingerprints, the skin of the deceased had been intimately touched on behalf of others.

"Then the skin will be handed over 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.

Do not underestimate these processes.

In many murder cases, the cause of death of the corpse cannot be found at a glance.

Although suffocation and sharp weapon injuries 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 root cause of anatomy.

Of course, from the perspective of forensic science, there are generally two purposes of dissection.

One is to figure out how the body died.

The second is to find out who the corpse is.

Of course, in general, neither is needed.

Carefully rolling up the skin, Lu Chuan continued: "When I was separating the resin just now, I found that there were half a centimeter long scars under the deceased's breasts. The other party most likely had breast augmentation surgery."

"I have already reported this situation, and Team Leader Sun and Team Leader Ren should have started to investigate."

At present, because the identity of the deceased has not been determined, any information that can guide the discovery of the identity of the deceased must be highly valued.

And breast augmentation surgery is obviously not a minor operation.

Whether the other party is in a hospital or other beauty institutions, it is possible to leave an identity record.

Shen Yan nodded, took the skin, and returned to the forensic laboratory.

Over there, Wang Changjiang's plane had already landed, and he rushed back overnight.

Early the next morning.

Everyone in the action group and the second group sprinkled out.

In the absence of new clues from the exhibition hall, all forces were concentrated on the clue that the deceased had had breast enlargement.

Last night, further examination of the skin by the forensic doctor basically confirmed some basic information about the deceased.

Female, judging comprehensively from the firmness and color of the skin, the deceased was between 20 and 40 years old.

He is 1.6 meters tall and weighs about [-] kilograms.

The time of death should be within a month.

The cause of death has not yet been found out.

Because the back part of the human skin is missing, the front part has no obvious trauma, and there is no toxicological reaction.

In addition, the abdomen of the deceased had no stretch marks, so he should have never given birth.

Therefore, the current clue is the wound on the bottom of the deceased's breasts, a scar left by a possible breast augmentation.

Of course, this is just a guess.

It is also possible that the deceased had suffered from some disease, such as atheroma excision, mammary gland hyperplasia excision, or other diseases, which may also leave scars at this location.

Wang Shuai, a team of investigators, has been in the police for 13 years and is the backbone of the Criminal Investigation Detachment.

For this investigation, he is in charge of Tianmei International Cosmetic Plastic Surgery Hospital.

These days, all plastic surgery hospitals seem to be able to hook up with the international community.

Just like the little baby in Tongguan Road, you ask her how long she has been doing it, two or three times.

Never the first time, never hundreds of times.

Anyway, if you don't ask, people won't tell.

You asked, that was two or three times, the family needed money urgently, and left when they had earned enough.

But next week she's there, and next month.

The family is always short of money.

Wang Shuai looked at the plaque on the door, and the ladies and sisters who were constantly pursuing truth, kindness and beauty, and walked in.
