Xiao Ran bent down, lifted up Du Keke's loose-growing pajama sleeves, and looked carefully at several scratches of varying degrees near his left wrist.

These scratches are relatively thin, and overall, the scratches are relatively shallow. The deepest one is just a scratch on the skin. The shallow one is a mark. In addition, the surface of the dead body has changed color, so if you don’t look carefully, you will really not find it.

"Brother Xiao, this injury..."

He Liang also came over to see him and was about to ask questions, but before he finished speaking, he was interrupted by Yu Yu's calm voice: "There is subcutaneous bleeding, test the wound."

"Tested, I thought it was created by the murderer when he killed him." He Liang's attention faded a little.

Xiao Ran stood up and said, "It's normal. Isn't it often reported that someone was stabbed more than ten or twenty times, and he committed suicide."

Indeed, the process of suicide is not as simple and direct as ordinary people imagine.

For some suicides, especially those without medical foundations, it takes some effort and attempt to complete suicide. The attempted wounds left before a fatal injury are often encountered in forensic science.

Test injuries often damage the superficial surface, the skin and muscles, and do not damage the internal blood vessels, nerves and important organs, which are not fatal enough.

In addition, temptation is not only the result of repeated attempts by the parties involved in suicide, but also reflects the painful struggle deep in the heart of the parties involved in suicide, and is also one of the important basis for forensics to determine that the way of death is a suicide.

With the test, He Liang and Yu Yu had already preconceived ideas and tended to be Du Ke who committed suicide.

But can one basically determine that it is suicide if one has tentative injuries?

Xiao Ran maintained a skeptical attitude, which was his habit of persistence. Even if the final conclusion appears, even if the final conclusion has been given, it must be read relatively dialectically and not believed in it.

Xiao Ran’s suspicion is not without basis.

First of all, Du Keke used wires to hang himself, why did he use wires instead of ropes?

When Xiao Ran first entered the door, he had already looked at it. The wires in the room were arranged through pipes, and the wires were all in the walls. In addition, the plug-in boards and appliances in the room were operating normally. In this case, will a fashionable and beautiful young woman have a wire at any time at home?

Even if this wire is lifted off the type of external plug board sold by Du Keke in the supermarket, it is not right. Generally, the plug board is made of thinner soft wire, while the one that is wrapped around Du Keke's neck is pure copper hard wire.

If a girl wants to hang herself at home, is it easy to find a rope or to cut out a thicker wire? It is obvious that it is the former, and it is enough to just pull two shoelaces out of the shoes.

Furthermore, if the wire was cut off by the deceased Du Keke from somewhere in his home, Xiao Ran looked around the house briefly and did not see any traces left after the thread cut.

Maybe it was taken away by Du Keke, but a person who was ready to die would still care whether the house was in chaos before he died?

In addition, Xiao Ran also noticed that the wire wrapped around Du Keke's neck had raised marks in the middle of the broken opening, which was obviously cut with vis. A fashionable and beautiful girl also had vises at home, which seemed unreasonable. Cutting wires with a knife was a regular operation.

Of course, these are just Xiao Ran’s first impressions and have not yet been verified.

After all, he just looked around incorrectly and had not had time to take a closer look. Maybe Du Keke really has vises at home, and he bought unused copper wire or the like.

Or is it that Du Keke’s home has no ropes, and the shoes they wear are not laces, and that the copper wire was picked up by Du Keke from outside?

Haha, a woman carrying a leather bag of tens of thousands of yuan deliberately picked up a remaining wire from outside and killed herself?

Moreover, when Xiao Ran and the others first entered the door, they saw that there were quite a few high-end sports shoes with shoelaces on the entrance hall.

The strange copper wire on Du Keke's neck was put aside first, and the second part on the body that made Xiao Ran suspicious was Du Keke's loose and grown pajama sleeves.

If Du Ke committed suicide, through the temptation of Du Ke Ke's left wrist, it can be inferred that she had a tendency to cut her wrist before hanging.

Those who commit suicide by cutting their wrists have tried several times before successfully cutting their wrists. If they wear clothes when cutting their wrists, their sleeves are often a subtle feature, that is, to prevent clothes from hindering self-injury. Suicides often roll up their sleeves before cutting their wrists to expose the corresponding parts of their bodies.

Correspondingly, similar behaviors are unlikely to occur in homicide cases.

Xiao Ran just looked at Du Keke's pajamas carefully. The sleeves were very long and thick, and they should have been worn when the temperature dropped sharply a few days ago. Her sleeves were essential for the wrist cutting project to prevent Du Keke from hurting himself.

If Du Keke had not rolled up her sleeves at that time, the tentative wounds on her wrists should have been relatively scattered, and it would not have been as concentrated as it is now.

Moreover, if Du Keke rolled up her sleeves at that time, then after giving up cutting her wrists, would she put down her rolled-up sleeves in such a state of eagerness to die?

As for what made Xiao Ran suspicious in the end, where was the tool that caused Du Keke to test his wrist?

"We saw this first in our body. Do you need to help you put the body down now?" Xiao Ran looked at Yu Yu who was making records and asked.

Yu Yu didn't raise her head, raised her hand and said, "No need, I haven't finished watching it yet, I'll talk about it later."

"That's OK."

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

"Okay." He Liang said in response.

Xiao Ran led He Liang out of the bathroom and was about to enter Du Keke's bedroom when suddenly a noise came from the door. It turned out that it was Wang Fugui, the younger brother of the deceased Du Keke, had a quarrel with Captain Ji of the police station.

"Why did the matter start to quarrel?" Xiao Ran asked a comrade from a police station.

The comrade from the police station said 'hi': "He just asked Team Ji what he thought about his sister's death. Team Ji said he would ask him to ask you professionals later, but Team Ji added another sentence that it is likely to be suicide, and then the kid started arguing, saying that we were all for nothing, and his sister's death was obviously murder..."

As soon as the comrade from the police station said this, Du Keke's younger brother Wang Fugui rushed in from the door and shouted excitedly: "My sister has no illness, and there are so many delicious foods that have not been eaten. How could she commit suicide? Even if she wants to commit suicide, what should she do with her mouse? How could she bear to let the mouse starve to death with such a kind person!"
