Theoretically, after a person passes through a place, he will leave his skin cells on the traces of his passing.
As long as these dander cells can be collected, the opponent's DNA information can be locked.
Of course, it is not easy to actually determine this kind of spatial trace, because the amount of dander cells is too small, and DNA identification cannot be carried out with current technical means. Only large pieces of dander or hair can be found. Maybe do DNA testing in this area.
"Let's start with the side where the murderer is carrying the body. The other party is carrying the body and has difficulty moving, so he is likely to leave something behind."
"There are also clothes on the body, especially on the chest. We will also check his clothes later. Maybe there will be something left behind when the other party carried the body.”
The reason why Lu Chuan was sure that the other party was carrying the corpse instead of holding it was because the footprints on the rotten leaves were different.
The way the murderer walks is different when carrying a body on his back and holding a body in his arms.
If the other party is walking holding the corpse, then because the weight of the corpse is on the chest, the murderer's posture is to lean back slightly to ensure that he does not fall. In this case, the center of gravity of the entire body will be backward. shift.
Compared with normal footprints, the traces on the back heels are heavier.
But if the opponent is carrying a corpse, in order to prevent the corpse from falling, the body should lean forward. In this case, the center of gravity will move forward slightly, causing the marks left by the forefoot to be deeper.
In addition, based on the terrain, the other party's path from the walking path to the place where the corpse was hung was downhill. It would definitely be easier for the other party to go down the mountain with the corpse on his back.
At this time, for the sake of safety, the other party is likely to hold on to the surrounding trees during the process.
In this case, the other party is likely to leave traces and clues.
Facts proved that Lu Chuan's judgment was correct, and soon Liu Guodong found two hairs on one of the trees.
Liu Guodong carefully removed the hair with tweezers and put it into the political evidence collection bag.
Of course, this does not mean that the hair must belong to the murderer. For example, the two young men and women who just entered the woods may have left hair on the tree, or even the hair of the corpse.
Whose it is, you have to go back and do a DNA test and then compare it, but no matter what, this is an important clue.
On-site investigation pays attention to meticulousness. Although there are three people on Lu Chuan's side, the work is not progressing quickly. After all, just cleaning out the new fallen leaves is a very time-consuming task.
Qin Yong and others are also very familiar with the process of on-site survey work and know that the other party cannot complete it within two or three hours, so they are also advancing other work simultaneously.
The first is to determine the identity of the deceased.
Qin Yong, Zhang Hui and others had just approached the corpse and made some observations.
Unfortunately, the degree of decomposition of the body was so severe that there was no way to obtain some basic information about the deceased from the face.
Of course, describing the actual situation as serious corruption is a bit too simplistic.
The degree of decay of the corpse is a bit disgusting even for people like Qin Yong and Zhang Hui who often deal with corpses.
The corpse was hanging on a tree branch. After half a month of wind and rain, it was very rotten. One of the two eyeballs was half hanging outside, and the other protruded eyelid was cloudy and looked like the eye of a dead fish.
The mouth and nose are rotten, especially the nose, which is like two black holes with maggots crawling around inside. One of the two ears has rotted and fallen to the ground, and the other is half rotten. Hang diagonally on the edge of the side face.
Fortunately, the body was covered with clothes and other parts were not exposed, so the specific extent of decomposition could not be seen. But the corpse oil dripped continuously under his feet, soaking into a small circle, and the stench came one after another, which was nauseating.
Qin Yong has handled many murder cases and has seen people hanged to death, but this is the first time that a corpse has rotted to such an extent outside for half a month out of the wind and rain. See.
No wonder the two young men and women who discovered the bodies for the first time are still on the roadside, their legs are weak and their eyes are blind, unable to walk.
After all, as police officers, Qin Yong, Zhang Hui and others couldn't accept the corpse in front of them for a while, let alone two ordinary people.
Moreover, the two of them went down there to fight in the field. Just when they were interested, they turned around and saw such a terrifying scene. They were not frightened to death. It was considered a good life for both of them.
As for why the two people did not smell the smell of corpses, it is actually easy to explain. The smell of corpses emitted by rotting corpses in the wild comes in waves.
Due to the flow of surrounding air, the smell of corpses seems to be trapped, sometimes here, sometimes there, and you can only smell it when it blows to where you are.
“The face of the corpse cannot identify the other party. Let’s wait for DNA identification and analysis to see if the comparison can be successful.”
Zhang Hui retched twice and suppressed the churning breakfast in his stomach: "Fortunately, the other party's clothes are still there. Let's go back and check the missing person database to see if there are any similar missing reports."
"Okay, if It would be best to be able to confirm the identity of the corpse. "
Qin Yong and others had already observed it on the way here. There is no surveillance at Wuhua Mountain, which means that the other party is unlikely to leave any image data. .
After all, this is not a scenic spot, just a hilltop with natural landscape.
There is no charge, no tickets are sold, and naturally there will be no investment in infrastructure.
It is already past three o'clock in the afternoon when the current survey comes to an end.
At this time, the young man and woman who were the first to find the body finally recovered a little.
At least you can have a normal conversation.
"I...we went down to play...but as soon as we entered...I turned around...ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood wastttuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu" broken.
According to the girl, the two didn't smell any corpse smell when they went down. They just felt a little unpleasant, but they didn't think too much about it.
The place where the two people worked was on the back of the big tree where the corpse was hung, which meant that the two people were separated from the corpse by a big tree.
Because of her posture, the girl turned her head and saw the body first, so you can imagine how frightened she was.
The boy was in a slightly better mood and could at least speak. No more stuttering.
“We had just started to do errands when we smelled a foul smell. My girlfriend couldn’t stand it and told us to go in another direction, but something happened.”
The two actually didn't provide much useful information.
When the two people saw the body, they were so frightened that they screamed. Then they struggled to climb up the hillside, shouting for help while climbing. When they were almost up, Lu Chuan and Shen Yan arrived.
After this young man and woman, let alone fighting in the woods, they will probably not dare to enter the woods in the future. (End of this chapter)
