National Forensic Doctor

Tang Feng's heart trembled as he listened to Jiang Yuan's answer. It was as if he had finished the exam and was correcting the answer. He suddenly heard the top student next door say two words coldly: Wrong.

"How do you feel?" Tang Feng knew it was unnecessary, but he still couldn't help but ask.

"The degree of leatheriness on the corpse is a bit abnormal." Jiang Yuan looked down at the corpse with harsh eyes, touched the surface of the corpse with his fingers, and looked at the scrotal sac of the corpse, shook his head and said : "Let's cut it open first and take a look."

Leatheryening is a forensic term that refers to a portion of the skin on the surface of a corpse that becomes leathery in appearance. The most vulnerable part to "leather-like" is the "scrotal sac", because the skin here is very thin and easy to lose water, and it can easily become black and purple, just like the leather of a handbag.

But leather-like formation takes time and conditions.

You don’t just want to become leathery, you can’t become leathery, and you don’t want to avoid it. A typical example is a boy with fair skin and good looks. He is fair and tender in the south, but if he can't think about it and rushes into the Qinghai-Tibet Plateau, the strong ultraviolet rays and strong winds can turn him into a boy in just a few days. His skin was dark and rough, and the process was the same as leather-like transformation.

Parts of the frozen body will also become leathery, so indentations will be more easily visible. Some old forensic doctors in the past may not have very accurate judgments. If they saw some indentations and did not dare to confirm them, they would freeze the body and see if there were any traces and what the traces looked like.

The same is true for the corpse in front of him. Many small marks on the skin are exposed, such as those on the knees, the crooks of the legs, and the arms. However, Jiang Yuan looked carefully and found that they were basically bruises and scrapes. .

Imagine that the victim is in a standing position and receives a heavy blow to the head. He may stagger two steps, bump into something around him, and suffer a minor scratch. Then he falls heavily to the ground, causing a fall injury. If If he could survive, or if he lived for a while, it was possible for these scars to recover, but if he died on the spot, the marks would be fixed.

However, these traces are not enough to solve the case.

Jiang Yuan took the knife and took advantage of his height to mark the body one by one. It was the traditional Chinese straight line cutting method, also called the one-word cutting method.

(T word, one word, Y word, inverted Y word)

Tang Feng was there to help Jiang Yuan.

The suturing after the primary dissection is to pull the flesh on both sides together and cross-sew them together. Therefore, the second dissection still has to be cut with a knife, and because the part is frozen, the sutures will naturally fall off when the cut is made this time. Get some minced meat out.

But it doesn't matter, because the corpse has been stored for several days, and even if it is in the ice coffin, there will still be a certain degree of decay. This is why meat in the freezer will go bad. In addition, meat that has been thawed repeatedly will go bad faster.

Therefore, after the second autopsy of the body, there is basically no anatomical value. If it is not for the request of the family, the third and fourth autopsies are usually just to confirm certain elements.

Therefore, Jiang Yuan also checked more carefully. After all, this autopsy will almost determine the final fate of the corpse. For the case, it is almost equivalent to deciding the fate of the case.

"This man is quite fat." Jiang Yuan used his hands to push away the discolored yellow fat, and there was a smell of havoc in his nose.

Generally, if the oil at home is spoiled, or the snacks with high oil content are not good, it will easily produce a stale smell. The smell from the corpse is stronger than the corpse odor.

Of course, the corpse odor is still there.

Tang Feng, wearing a mask, said "Hmm" and said: "The weight must be 180 kilograms. The fact that the body was not dismembered means that the murderer probably did not act alone."

"The murderer was a man, and he was fatal with one blow, but he might have asked someone for help when he abandoned the body." Jiang Yuan sighed and said, "If the victim is a village doctor, everyone in the village is actually a suspect. But for now I’m not sure whether this situation was premeditated or not.”

If the murderer abandons the body at the scene, this kind of blunt instrument killing that kills with one blow is often a killing of passion. Because if you intend to kill someone, you usually want to ensure that the victim is dead, so there will often be follow-up shots or follow-up attacks.

But after the stage of abandoning the body, it is hard to say whether it was premeditated or not, because the murderer is right in front of him and his death is completely guaranteed. And, because the crime isn't over yet, the killer's attention may be diverted.

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

There is no such thing as debris, and it cannot be used for examination of trace evidence. This also shows from another aspect that the victim was indeed wearing pants before his death.

——This is not a nonsense guess. It is not uncommon for victims to die while half-naked or naked. It is also normal for someone to put on clothes and pants after death. In order to cover up their ugliness, some family members even destroy the scene and give The state of the deceased's clothing.

As for the testing of trace evidence on clothes and pants, although it is possible, it does not seem necessary for the time being. On the one hand, the environment at the scene was complicated. The deceased had been lying in the reed swamp for a long time, and there was an excess of physical evidence on his pants. On the other hand, even if there were physical evidence from the first scene on the clothes, it is difficult and impossible to distinguish it now. Recognized.

This can be said to be a place where throwing corpses in the wilderness is more complicated than burying them. If the body is buried, because the underground environment is stable, the body will actually remain in the same state as when it left the murderer. Trace evidence often yields more discoveries.

From this point of view, if there are separate classes for murderers, the corpse dumping class in the wilderness and the corpse excavation and burial class should be two majors and two teaching directions.

Jiang Yuan's second dissection took more than an hour. Finally, he left the dissected body and sat on another cold dissecting bed next to him. He pondered for a long time and asked, "What do you think?"

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

If he had any idea, why would he wait for a second autopsy?

Jiang Yuan consciously respected the forensic doctor in charge. After asking, he nodded and said, "I don't think the time of death previously determined for this body is appropriate, but I can't judge the specific time of death yet! We need to check it carefully. it!"

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

The time of death of his LV6 was determined. Now after re-anatomy, it is difficult to determine the accurate time of death. This in itself is the biggest problem.

What kind of good corpse can be so stubborn?
