Chapter 840 Stubborn Corpse

Tang Feng's heart trembled when he heard Jiang Yuan's answer, just like when he finished the exam and checked the answers, he suddenly heard the top student next door coldly spit out two words: wrong.

"What do you feel?" Tang Feng knew it was unnecessary, but he couldn't help asking.

"The degree of leather-likeness of the corpse is a bit abnormal." Jiang Yuan looked down at the corpse with a harsh look, touched the surface of the corpse with his fingers, and looked at the scrotum of the corpse with emphasis, then shook his head and said, "Let's open it up first."

Leather-likeness is a special term for forensic doctors, referring to a part of the skin on the surface of the corpse that has become leathery. The part that is most likely to "leather-like" is the "scrotum", because the skin here is very thin and easy to lose water, and it is easy to turn black and purple, like the leather of a handbag.

But leather-likeness requires time and conditions.

It is not possible to leather-like if you want it to be leathery, nor can it be avoided if you want to. A typical example is a boy with fair skin and good looks. He is fair and tender in the south, but if he is upset and rushes to the Qinghai-Tibet Plateau, the strong ultraviolet rays and strong winds will only take a few days to make his skin black and rough. This process is the same as leatherization.

The frozen corpse will also partially show leatherization, so it is easier to show indentations. Some old forensic doctors in the past may not have very accurate judgment. When they see some indentations, they dare not confirm them, so they will freeze the corpse to see if there are any marks and what they look like.

The corpse in front of him is also like this. Many small marks on the skin are revealed, such as those on the knees, the bends of the legs, and the arms. But Jiang Yuan looked carefully and found that they were basically falls and abrasions.

Imagine that the victim was standing and was hit hard on the head. He might stagger a few steps, hit something nearby, and get a slight scratch. Then he fell heavily to the ground and got injured. If he survived or lived for a while, these scars might recover. But if he died on the spot, the scars would be fixed.

However, these scars were not enough to solve the case.

Jiang Yuan took the knife and took advantage of his height to cut a "one" on the body. This is the traditional Chinese straight line cutting method, also called "one-line cutting method".

Tang Feng was helping Jiang Yuan.

The suture after the first dissection is to pull the meat on both sides together and cross-sew them together. Therefore, the second dissection still needs to be cut open with a knife. And because it is partially frozen, some meat will naturally fall out of the suture when it is cut open this time.

But it doesn't matter, because the body has been stored for several days. Even in the ice coffin, there will still be a certain degree of corruption. This is why the meat in the ice storage will go bad. In addition, the meat that is repeatedly thawed will go bad faster.

Therefore, after the second autopsy, the body is basically worthless. If the third and fourth autopsies are not for the request of the family members, they are usually just to confirm certain factors.

Jiang Yuan also examined it more seriously. After all, this autopsy almost determines the final fate of the body. For the case, it is almost equivalent to determining the fate of the case.

"This person is quite fat." Jiang Yuan used his hand to push away the discolored yellow fat, and a rancid smell came from his nose.

Generally, if the oil at home is spoiled, or the snacks with a high oil content are not good, it is easy to have a rancid smell. If you smell it from the body, it is a little stronger than the corpse odor.

Of course, the corpse odor is still there.

Tang Feng wore a mask and said, "He weighed about 180 pounds. There was no dismemberment, which means that the murderer was probably not acting alone."

"The murderer was alone, and the blow was fatal, but the body was abandoned probably to ask for help." Jiang Yuan sighed and said, "If the victim is a village doctor, everyone in the village is actually a suspect. But in the current situation, I'm not sure if it was premeditated."

If the murderer abandoned the body at the scene, this kind of blunt weapon killing that was fatal in one blow is often a passion killing. Because if the murderer is premeditated, he usually wants to ensure the death of the victim, so there will often be a finishing blow or finishing blow.

But after the stage of abandoning the body, it is hard to say whether it was premeditated, because the murderer is right in front of him and can completely ensure death. Moreover, because the crime has not yet ended, the murderer's attention may also be diverted.

"Leave this matter to Liu Chu to figure out." Jiang Yuan looked at the three chambers, took a magnifying glass, looked carefully at the location of the abrasion, and finally shook his head in disappointment.

There are no debris or other things, so it is impossible to use them for trace evidence examination. This also shows from another aspect that the victim was indeed wearing pants before his death.

——This is not an absurd guess. It is not uncommon for victims to die half-naked or naked. It is also normal for people to put clothes and pants on them after death. Some families even destroy the scene and put clothes on the dead to cover up their shame.

As for the determination of trace evidence on clothes and pants, although it is possible, it seems unnecessary for the time being. On the one hand, the environment at the scene is complicated, and the dead body has been lying in the reed marsh for a long time, so there is too much evidence on the pants. On the other hand, even if there is evidence on the clothes at the first scene, it is now difficult to distinguish and cannot be identified.

This can be said to be a place where dumping corpses in the wilderness is more complicated than burying corpses. If the corpse is buried, because the underground environment is stable, the corpse actually remains in the state when it left the murderer. Trace evidence can often lead to more discoveries.

From this perspective, if the murderer is divided into classes, the wilderness dumping class and the deep digging and burying class should be two majors and two teaching directions.

Jiang Yuan spent more than an hour on the second autopsy. In the end, he left the dissected corpse and sat on another cold autopsy bed next to him. He pondered for a long time and asked: "What do you think?"

Tang Feng is in his thirties, and his eyes are clear as if he had just graduated: "I have no idea."

If he had an idea, why would he wait for the second autopsy.

Jiang Yuan consciously respected the responsible forensic doctor. After asking, he nodded and said: "I think the time of death of this corpse that was previously judged is not appropriate, but the specific time of death is not easy for me to judge for the time being! I have to check it carefully!"

When Jiang Yuan said this, his expression became very serious.

His LV6 time of death identification, now after re-dissecting, is difficult to determine the exact time of death, which is the biggest problem.

What kind of corpse can be so stubborn?
