Xiao Ran leaned down, lifted the sleeves of Du Coco's loose and long pajamas, and carefully looked at several scratches of different shades near his left wrist.

These scratches are relatively fine, on the whole, the scratches are relatively shallow, the deepest is only a scratch on the epidermis, the shallow is a mark, and the surface of the deceased's body has changed color, if you don't look carefully, you can't really find it.

"Brother Xiao, this hurts ......"

He Liang also came over to take a look, and was about to ask a question, but before he finished speaking, he was interrupted by Yu Yu's calm voice: "There is subcutaneous hemorrhage, test injury." ”

"Temptation injury, I thought it was the murderer when he killed him. The attention in He Liang's eyes faded slightly.

Xiao Ran got up and said, "It's normal, isn't it often reported that someone was stabbed by a dozen or twenty knives, and he died by suicide." ”

Indeed, the process of suicide is not as simple and straightforward as ordinary people think.

For some suicidal people, especially those who have no medical foundation, it takes a lot of effort and attempt to complete suicide, and the tentative wound left before forming a fatal injury is the tentative wound often encountered in forensic science.

Tentative injuries often damage the superficial surface, skin, and muscles, but do not damage the internal blood vessels, nerves, and vital organs, and are not fatal.

In addition, the test injury is not only the result of repeated attempts when the person commits suicide, but also reflects the deep inner pain struggle of the person in the process of suicide, and is also one of the important bases for the forensic doctor to determine the method of death as suicide.

With the temptation injury, it is obvious that He Liang and Yu Yu have preconceived ideas, and their hearts are inclined to Du Keke to commit suicide.

But can it be concluded that it is suicide if there is a test wound?

Xiao Ran maintained a skeptical attitude, this is a habit he has always adhered to, until the final conclusion appears, even if the final conclusion has been given, he must look at it relatively dialectically, and he cannot be trusted.

Xiao Ran's suspicions were not unfounded.

First of all, Du Coco uses wires to hang himself, why does he use wires instead of ropes?

Xiao Ran had already seen it when he first entered the door, the wires in this room were all arranged through pipes, the wires were all in the wall, and the plug-in board appliances in the house were operating normally, in this way, a fashionable and beautiful young woman, would she have a wire at home at any time?

Even if this wire is removed from the kind of external plug-in board sold in the supermarket, then it is not right, generally the plug-in board is used thinner soft silk wire, and the plug-in board is pure copper hard wire.

If a girl wants to hang herself at home, is it easier to find a rope or to cut out a thicker wire? Obviously, it is the former, and it is enough to draw two laces from the shoe.

Moreover, if this wire was cut off by the deceased Du Keke from somewhere in the house, but Xiao Ran took a brief look around the house and did not see any traces left after the cut.

- Maybe it was cleaned up by Du Keke, but a person who is ready to die, will he still care about the chaos in the house before he dies?

In addition, Xiao Ran also noticed that the wire on Du Keco's neck had a raised mark in the middle of the fracture, which was obviously cut with a vice or something. A fashionable and beautiful girl, who also has a vice at home, seems to be unreasonable, and cutting the thread with a knife is the routine operation.

Of course, these are just Xiao Ran's first impressions, and they haven't had time to verify yet.

After all, he just took a wrong look just now, and before he had time to take a closer look, maybe Du Keke really had a vice at home, bought unused copper wires and the like.

Or, there is no rope at Ducoco's house, and the shoes he wears are all unlaced, and this copper wire was picked up by Du Coco from outside?

- Hehe, a woman carrying a leather bag of tens of thousands of yuan, deliberately picked up a leftover wire from someone else from outside and came back to commit suicide?

And when Xiao Ran and the others first entered the door, they saw that there were a lot of high-end sneakers with laces on the shoe rack at the entrance.

The weirdness of the copper wire on Du Keke's neck was put aside, and the second thing on the corpse that made Xiao Ran suspicious was Du Keke's loose and long pajama sleeves.

Assuming that Du Ke committed suicide, it can be inferred that Du Keke had a tendency to cut her wrist before hanging herself through the test wound on her left wrist.

If there is clothing when cutting the wrists, their sleeves often have a subtle feature, that is, in order to prevent clothing from hindering self-injury, the suicide person will often roll up the sleeves before cutting the wrists, exposing the corresponding parts of the body.

Correspondingly, in homicide cases, similar acts are unlikely.

Xiao Ran took a closer look at Du Keke's pajamas just now, the sleeves were very long and thick, they should have been worn when the temperature plummeted a few days ago, and her sleeves were indispensable in the project of cutting wrists, which would hinder Du Keke's self-injury.

If Du Keke hadn't rolled up her sleeves at that time, the test wounds on her wrists should have been relatively scattered, and it would not have been relatively concentrated like now.

Moreover, if Du Keke rolled up her sleeves at that time, then did she put down her sleeves after giving up cutting her wrists, and in such a state of mind that she desperately wanted to die?

As for the last thing that made Xiao Ran suspicious, where was the tool that caused the test injury on Du Keke's wrist?

"Our corpse saw this first, do you need to help you put the corpse down now?" Xiao Ran looked at Yu Yu, who was taking notes, and asked.

Yu Yu didn't raise his head, raised his hand and said, "Don't use it yet, I haven't finished reading it yet, I'll talk about it later." ”

"That's fine. ”

Xiao Ran nodded, and then said to He Liang: "Let's go out now and focus on the bedroom, living room, and kitchen, and by the way, ask Zhang Lei about their on-site investigation, whether they have collected blades, vises, truncated wires, etc." ”

"Okay. He Liang responded.

Xiao Ran led He Liang out of the bathroom and was about to walk into Du Keke's bedroom, when suddenly a commotion came from the door, it turned out to be Wang Fugui, the younger brother of the deceased Du Keke, who quarreled with Captain Ji of the police station.

"What's going on?" Xiao Ran asked a comrade from the police station.

The comrade from the police station said 'hi' and said: "He just asked the Ji team what he thought of his sister's death, and the Ji team said that he would let him find your professional later, but the Ji team added another sentence with a high probability of suicide, and then this kid quarreled, saying that we all ate dry food for nothing, and his sister's death was obviously murder......

As soon as the comrades at the police station said this, Du Keke's younger brother Wang Fugui rushed in from the door and shouted excitedly: "My sister is not sick at all, and there are so many delicious foods that she has not eaten, how can she commit suicide? Even if she wants to commit suicide, what will she do with this mouse, how can she bear to let this mouse starve to death if she is such a kind person!"

The more Wang Fugui spoke, the more excited he became, and Captain Ji dragged him to the door: "Don't rush in, what if you destroy the scene!"
