The crackdown on organized crime began with the arrest of the mother-in-law.

Chapter 675 Forensic Examination, Cutting Marks

Forensic medicine is a highly experience-based profession, and its specializations are relatively narrow.

The number of corpses a forensic pathologist has dissected and the number of crime scenes he has examined all determine his skill level.

In recent years, forensic medicine has gradually developed and has adopted many new technologies.

However, the profession of forensic medicine has existed since ancient times.

The practice of dissecting and examining corpses to determine basic information about the deceased has existed since ancient times. However, the techniques used in the past were not as advanced as they are now.

Since the advent of the modern era, forensic medicine has been greatly influenced by the West.

However, ancient China already had some works on forensic medicine.

After a person dies, the body will show very obvious changes at different stages.

Qin Chuan had acquired this knowledge through system rewards, so he knew that the old forensic doctor could determine at what stage the victim's skin was peeled off and what kind of reaction it would produce.

After a person dies, although the person is no longer there, it does not mean that all bodily functions stop.

A person is composed of countless cells. After death, the nervous system eliminates the heart, which stops beating. The whole body seems to be in a static state, but in fact, cell division continues.

A clear example is that when people who are buried in the ground are opened after a period of time, it is found that their fingernails have grown to varying degrees.

In many movies and TV shows, the lively zombies have very long fingernails. This is not just for the sake of filming effects, but because the fingernails do not actually stop growing completely after a person dies.

Generally speaking, from the time of death until the body decomposes, nail growth does not completely stop; in fact, it may even grow faster than normal.

Compared to nail growth, skin changes are relatively short-lived. Within a short period after death, roughly one day or 24 hours, the degree of skin laxity will show a noticeable change.

Immediately after death, the skin of a person no longer has the ability to heal.

However, the skin's activity did not completely disappear; in fact, the skin was contractile during the first hour after death.

After death, the skin contracts beforehand, but this contraction is relatively small and the skin remains relatively taut. This is one of the most important reactions that occur on the surface of the body before the event occurs.

After the skin has contracted, it will enter a relatively stiff state.

In this state, the skin resembles damaged leather.

It has lost its flexibility.

After death, the elasticity of the skin gradually disappears.

During this process, a very useful and distinctive product for forensic examination is formed: livor mortis.

After a person dies, whether the body has been moved can be inferred from the formation of livor mortis.

The forensic expert continued his report.

"Based on the on-site investigation and the criminal police's investigation, we found bloodstains belonging to Da Tang at the scene. Initially, the deceased was lying flat under the blackboard, and then the body was cut up. This process lasted for about an hour and a half. After the skin was cut off, the suspect rearranged the body into the kneeling position we see now."

"Because the time of death was relatively short at this point, and the time frame was not yet fully established, the suspect tied the body to a chair when securing it, and the chair served to stabilize it."

The veteran forensic doctor described the process in great detail, explaining every single detail, including every cut mark on the skin.

"The entire skin was cut and assembled multiple times before being pinned to a blackboard by the suspect with thumbtacks to form a butterfly pattern. However, after comparing the scraps, we found that all the skin pieces together could not completely cover the body, meaning that some skin was missing."

"Also, everyone, take a close look at the cut marks on these skins."

The veteran forensic doctor enlarged the photo.

"The tool the killer used to cut the skin should have been a sharp weapon, such as a dagger, with a very sharp edge. But why did the killer use a dagger to cut the skin, but use some kind of cone to kill the suspect?"
