Zhang Yaoming saw the change in Chen Yan's expression.

With a wry smile, Zhang Yaoming handed Chen Yan a copy of the on-site investigation materials.

"Group leader Chen, this matter... don't talk about you, I was there at the time, and I don't believe it."

32 knives in the body, suicide...

I am afraid that this kind of story would not dare to be written like this in a novel.

Suicide, generally speaking, no matter what the purpose of the deceased is to end his own life, but due to the self-subconscious self-protection mechanism of the human body, when committing suicide, the suicide person will most likely choose the way he thinks is the fastest way to end his life.

In other words, they will subconsciously choose the least painful way to end their lives.

Such as jumping off a building.

And he cut himself 32 knives, this kind of suicide method is similar to giving himself Ling Chi...

No wonder Zhang Yaoming reported the case to the Liao Provincial Detective Brigade.

This kind of thing, even if Chen Yan encounters it, he may not be able to hold it, and he has to check it repeatedly. Opening the file, Chen Yan read it carefully, and Zhang Yaoming was also introducing the situation of the case.

"The deceased's name is Wang Luyao, 36 years old, a native of Dan City. The deceased's mother reported the case this morning."

"We didn't find any traces of other people committing crimes at the scene, footprints, fingerprints, dander and hair, nothing."

"The 32 stab wounds on the deceased were all within reach of the deceased's right hand."

"Moreover, many of the knife wounds were tentative wounds, and in addition to the surveillance video in the corridor where the deceased lived, it can be confirmed that no outsiders entered the deceased's home before her mother entered."

"So, we preliminarily determined that the deceased committed suicide."

What Zhang Yaoming said was very simple, but in fact there was a sense of helplessness. The reason why the deceased committed suicide was that no trace of outsiders was found at the scene.

The deceased, Wang Luyao, was 36 years old. Her husband was on a business trip three days ago, and she is still in Shenshi. Her mother called Wang Luyao this morning but was not connected. Fearing that something might happen to her daughter, she went home to look for her. Wang Luyao's mother entered Wang Luyao's community at 7:54 this morning, as evidenced by the surveillance video.

Because the old man had the key to Wang Luyao's house, he opened the door at 7:59 and called the police after that. At 8:11, Zhang Yaoming led the team to the scene.

Later, after two hours of on-site investigation and surveillance video investigation and evidence collection, it was preliminarily judged that the deceased committed suicide.

But because there were too many stab wounds on the deceased, Zhang Yaoming chose to report the case and asked the serious crime team to come over for support.

It is now 13:08 in the afternoon, and Chen Yan is already sitting in the car rushing to the scene.

Judging from the dossier, the judgment of the Dan City Police Department responsible for on-site investigation and autopsy should be correct.

Suicide or homicide is the first judgment of the investigators on the deceased.

Generally speaking, it is easier to judge from the injuries of the corpses at the scene and the traces of the scene.

For example, wounds, in the on-site investigation and identification, the classification of wounds is very detailed.

For example, sharp weapon injuries can be divided into scratches, stab wounds, abrasions, etc.

According to the shape of the wound, it can also be divided into open wound, closed wound and so on.

Each type of wound has different characteristics. Combined with the analysis of blood traces, many details of when the deceased was injured can be determined.

As for the traces of outsiders at the scene, this is a better judgment.

Of course, this does not rule out that the other party can clean up the traces. In this case, it is very possible that no traces were found.

The specific situation, Chen Yan still has to go to the scene to finally determine.

The car drove very fast, and arrived at the scene of the crime in less than 20 minutes after getting off the highway intersection.

The floor where the incident happened has been cordoned off. After getting out of the elevator, Chen Yan saw that many detectives were still working.

Detectives are also investigating and visiting the neighbors of the deceased.

"Has the time of death been determined?"

Zhang Yaoming nodded: "It's confirmed, it was 3 o'clock in the morning today, and the cause of death was shock death caused by excessive blood loss."

At 3:00 in the morning, it has been 10 hours by now.

During this time period, the corpse is still in the early corpse phenomenon stage after death.

After the death of the human body, the corpse will undergo a series of changes, which can be divided into early, middle and late corpse phenomena according to the time.

Early corpse phenomenon generally refers to the body changes that occur within 24 hours after death.

The door was already open, Chen Yan observed it before entering.

The inside and outside of the door are relatively clean, without dust, and there are no obvious scratches on the lock.

In other words, the door should not have suffered damage.

The moment he walked in, Chen Yan glanced at the cat's eyes.

With the visual gene lock turned on, every detail on the cat's eye was presented in Chen Yan's mind.

There is dust in the gap, and there are no scratches or signs of prying around the cat's eye.

The anti-theft door used by the deceased's house was an ordinary mechanical lock. Chen Yan, who had been rewarded by the system and specialized in lockpicking skills, was very familiar with the technical opening of this kind of door.

In addition to violently destroying the door lock, most technical locks are opened by opening the cat's eye, and then using a special-shaped wire to hook the door handle inside, and the door is opened.

But judging from the present, there is no sign of the cat's eye being pried, that is to say, without considering the surveillance, if there is a murderer, then the other party can only enter the room by opening the door normally with a key.

Of course, it would also make sense if the deceased opened the door for the other party.

Entering the room, some scenes in the living room came into view.

On the edge of the sofa, a blood-stained corpse was leaning on the sofa.

There were a lot of sprayed blood around, the sofa seemed to have been soaked in blood, and there was also a pool of blood on the ground.

Generally speaking, the blood volume of an adult male is 5-6 liters, and that of an adult female is 4-5 liters.

Although not all the blood in the deceased's body flowed out, judging from the situation at the scene, at least two-thirds of it had flowed out.

Putting on the shoe covers and gloves, Chen Yan walked into the room and observed carefully.

At this time, the room where the deceased lived had completed the on-site survey, and the only person who followed Chen Yan in was Zhang Yaoming, the captain of the Dan City Criminal Police Team.

Zhang Yaoming, who had worked with Chen Yan, knew Chen Yan's style of handling cases very well. When the other party was investigating the scene, Zhang Yaoming quietly followed behind Chen Yan and did not speak.

Immediately, Chen Yan activated the olfactory gene lock and vision gene lock.

The smell in the room is very mixed.

But the strongest smell belonged to the dead man before him, and there was another person whose smell was as strong as the dead man's.

It should be the husband of the other party.

"Has the husband of the deceased returned?"

"He's back. UU Reading is now in the team with the deceased's mother for questioning."

Chen Yan nodded.

For married couples, if one party dies, from Chen Yan's experience in handling cases, the other party is likely to be suspicious.

But this case is obviously not the case. Wang Luyao's husband has been on a business trip in Shen City, and there are witnesses there. He just rushed back from Shen City after receiving a call this morning.

"The husband of the deceased is Zhao Guang, 37 years old, and an engineer. We have checked his whereabouts in the past few days. He was indeed on a business trip in Shenyang City and has never returned. There are colleagues who work and live with him there. testify."

Obviously, Zhang Yaoming has already done work in this area in advance.

"Have you come into contact with this Zhao Guang?"

Zhang Yaoming nodded: "I have contacted her, and the other party reacted strongly to Wang Luyao's death."

"Zhao Guang firmly believes that the deceased Wang Luyao cannot commit suicide."
