I'm not a super cop

Chapter 474

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

These scratches are relatively thin, and generally speaking, the scratches are relatively shallow. The deepest scratches are just scratches on the skin, and the shallow ones are just an imprint. In addition, the surface of the dead body has changed color. If you don't look carefully, you can't really find it.

"Brother Xiao, this injury..."

He Liang also came over to look, and was about to ask a question, but was interrupted by Yu Yu's calm voice before he could finish speaking: "There is subcutaneous bleeding, test the wound."

"Testing injury, I thought it was caused by the murderer when he killed him." The focus in He Liang's eyes faded a little.

Xiao Ran stood up and said, "It's normal, isn't it often reported that a certain person was stabbed more than ten or twenty times and committed suicide?"

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

For some suicides, especially those who have no medical basis, it takes a lot of effort and attempts to complete suicide, and the attempted wounds left before fatal injuries are often encountered in forensic medicine. trial injury.

Probe wounds often damage superficial skin and muscles, but do not damage internal blood vessels, nerves and important organs, and are not fatal.

In addition, the test wound is not only the result of repeated attempts of the person involved in suicide, but also reflects the painful struggle in the heart of the person involved in the suicide process, which is also one of the important basis for forensic doctors to determine the method of death as suicide.

With tentative wounds, it is obvious that He Liang and Yu Yu have preconceived ideas, and their hearts are inclined to Du Keke's suicide.

But can it be basically concluded that it is suicide if there are tentative injuries?
Xiao Ran maintains a skeptical attitude. This is a habit he has always adhered to. Before the final conclusion comes out, even if the final conclusion has been given, he has to look at it relatively dialectically, and he cannot believe it.

Xiao Ran's suspicion was not without grounds.

First of all, Du Keke used wires to hang himself, why did he use wires instead of ropes?
Xiao Ran had already seen it when he first entered the house. The wires in this room are arranged through pipes, and the wires are all in the wall. In addition, the plug-in boards and electrical appliances in the house are in normal operation. Have a cord at hand at all times?

Even if this wire was pulled off by Du Keke from the external plug board sold in the supermarket, it is not right. Generally, the plug board uses thinner soft silk wires, and the one wrapped around Du Keke's neck is Solid copper wire.

If a girl wants to hang herself at home, is it easier to find a rope, or cut out a thicker wire?Obviously the former, just pulling two laces out of the shoe will suffice.

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

——Maybe it was cleaned up by Du Keke, but a person who is ready to die, will he care if the house is messy before he dies?

In addition, Xiao Ran also noticed that the wire wrapped around Du Keke's neck had a raised mark in the middle of the break, which was obviously cut with a vise or something.A fashionable and beautiful girl has a vise at home. It seems unreasonable. Cutting the thread with a knife is a routine operation.

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

After all, he just looked around by mistake just now, and he hasn't had time to take a closer look. Maybe Du Keke really has a vise at home, bought unused copper wires, and the like.

Or, there is no rope in Du Keke's house, and the shoes he wears are all without laces, and Du Keke picked up this copper wire from outside?
——Hehe, a woman with a purse worth tens of thousands of dollars deliberately picked up a wire left by someone else and committed suicide?

And when Xiao Ran and the others first entered the door, they saw a lot of high-end sports shoes with laces on the shoe rack in the entrance.

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

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

And those who commit suicide by cutting their wrists are those who successfully cut their wrists after several trials. If they wear clothes when cutting their wrists, their sleeves often have a subtle feature, which is to prevent clothing from hindering self-injury. The sleeves are often rolled up before the wrist is cut, exposing the corresponding parts of the body.

Correspondingly, in homicide cases, similar behavior is unlikely.

Xiao Ran took a closer look at Du Keke's pajamas just now. The sleeves are very long and thick. They should have been worn when the temperature dropped sharply a few days ago. Her sleeves, which are indispensable in the wrist-cutting project, will hinder Du Keke hurt himself.

If Du Keke hadn't rolled up her sleeves at that time, the test wounds on her wrist should be relatively scattered, and it is impossible for them to be relatively concentrated like they are now.

Moreover, if Du Keke rolled up her sleeves at that time, then after she gave up cutting her wrists, did she specifically 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 the test injury on Du Keke's wrist?
"Our corpse is here 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 her head, she raised her hands and said, "No need, I haven't finished 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. By the way, I would like to ask Zhang Lei and the others about their on-site investigation, whether they have collected blades, pliers, cut wires and so on. "

"Okay." He Liang said in response.

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

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

The comrade at the police station said 'hi' and said: "He just asked Captain Ji what he thought of his sister's death, and Captain Ji said that he would ask your professional to talk about it later, but Captain Ji added that there is a high probability that it is Suicide, and then this kid started arguing, saying that we are all living for nothing, and his sister's death is 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 left to eat, how could she commit suicide? Even if she wants to commit suicide, what will happen to her mouse, she is such a kind person, how could she have the heart to let this mouse starve to death!"

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