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 leather-like transformation of 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 focused on the scrotal sac of the corpse, shook his head and said: "Let's cut it open and take a look first."
Leather-like is a special term used by forensic doctors. It refers to a part of the skin on the surface of the corpse that has turned into a leather-like appearance. The most likely part of "leather-like" is the "scrotal sac" because the skin here is very thin. , and it loses water easily, and it easily turns black and purple, just like the leather of a handbag.
But leather-like transformation requires time and conditions.
It doesn't mean that you can become leathery if you want to, nor can you avoid it if you 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, he rushes into Qinghai-Tibet The plateau, the strong ultraviolet rays, and the windy weather can turn his skin black and rough in just a few days. This process is the same as leather.
Parts of the frozen corpse will also appear leather-like, so it is easier to show indentations. Some old forensic doctors in the past may not have very accurate judgments. They did not dare to confirm certain indentations when they saw them. We will freeze the body and see if there are any traces and what they look like.
The same was true for the corpse in front of him. Many small marks on the skin were 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 scratches. .
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, resulting in a fall. If If he survives, or if he lives for a while longer, it is possible for these scars to recover, but if he dies on the spot, the marks will be fixed.
However, these traces are not enough to solve the case.
Jiang Yuan took out the knife and took advantage of his height to cut a single line on the corpse. It was the traditional Chinese straight line cutting method, also called the one-line cutting method.

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 body has been stored for several days. Even if it is in an ice coffin, there will still be a certain degree of decay. This is why the meat in the icehouse will go bad. In addition, it has been thawed repeatedly. Meat spoils faster.
Therefore, after the second autopsy of a corpse, there is basically no anatomical value. If the third and fourth autopsies are not done at the request of the family, they are usually just to confirm certain elements.
Therefore, Jiang Yuan also examined it more carefully. After all, this autopsy will almost determine the final fate of this corpse. For the case, it will almost determine the fate of the case.
"This man is quite fat." Jiang Yuan used his hands to push away the discolored yellow fat, and a smell of havoc came from his nose.
Generally, if the oil in the home is spoiled, or the snacks with high oil content are not good, it will easily produce a stale smell. When you smell it from a corpse, it 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 is about 180 kilograms. There was no dismemberment, indicating 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 if this situation was premeditated or not.”
If the murderer abandons the body at the scene, this kind of fatal blunt-force killing is often a killing of passion. Because when a murder is planned, the victim usually wants to ensure that the victim is dead, so there is often a follow-up blow or a follow-up blow.
But after the stage of abandoning the corpse, it is difficult to say whether it was premeditated or not, because the murderer is right in front of him and his death is completely guaranteed. Moreover, because the crime has not yet ended, the murderer's attention may also 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.
Without such things as debris, it would not be possible to use it 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 victims
The state of the deceased's clothing.
As for the measurement of trace evidence on clothes and trousers, although it is possible, it does not seem necessary for the time being. On the one hand, the environment at the scene is complicated, the deceased has been lying in the reed swamp for a long time, and there is already an excess of physical evidence on the trousers.
On the other hand, even if there is physical evidence from the first scene on the clothes, it is now difficult to distinguish and impossible to identify.
This can be said to be where dumping a body in the wilderness is more complicated than burying it. 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. More trace evidence can often be found.
From this point of view, if there are 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 is 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 think the time of death previously determined for this body is inappropriate, but the specific time of death is not yet difficult for me to judge! 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 actually difficult to determine the accurate time of death. This is the biggest problem in itself.
