"Please step back, thank you for your cooperation. Gu Chen once again extended the cordon outward, stopping the crowd who were trying to get closer.

There were many onlookers in the community, most of them were the elderly, women and children, and when Gu Chen said this, everyone was also very cooperative and took the initiative to withdraw to a safe distance.

After setting up the cordon, Gu Chen returned to Officer Wang's side.

For each case, Gu Chen was very much looking forward to it, he only needed to complete three cases within fifteen days now, and he could get a primary treasure box, and there was no upper limit.

This is easy to give Gu Chen full room to play, so Gu Chen's expectations for the case are naturally stronger than other policemen.

"Senior Brother Gu Chen, are you okay?" Looking at the way the corners of Gu Chen's mouth were raised, Lu Weiwei was a little confused.

If you want to deal with this kind of murder case, although the old comrades of the three groups are looking forward to it, they will not be as exaggerated as Gu Chen, right?

Thinking about it this way, Gu Chen is indeed different from ordinary people in some aspects, at least in terms of appearance, he is in the C position.

"I'm wondering why Senior Brother Wang hasn't moved for a long time. Gu Chen watched Officer Wang stay by the window for a long time, but he didn't make the slightest move, and couldn't help but wonder in his heart.

At this time, the property manager gave the answer: "The deceased died in the room he rented, but the whole room was sealed, and there was only one person-sized glass window, and the window was completely closed and fixed. ”

"In other words, no one can open this door except the deceased himself, right?" Gu Chen asked.

"That's right. The property manager nodded: "We used the landlord's spare key, which could not be opened at all, and it was obviously locked by the deceased from the inside." ”

"Is there any other place where I can go in?" Gu Chen took out the transcript and asked for useful clues again.

The property manager thought for a moment and said, "In addition, there is a vent with a fan in the room, but it is so small that people can't get out of it at all." ”

Officer Wang frowned: "In other words, this is a case of suicide in a closed room?"

"If there is no other possibility, I think it should be. Lu Weiwei on the side also hurriedly agreed.

From the time he received the call from the police center, Officer Wang still imagined that this was a homicide case, and even listed various possibilities in his mind.

But now it seems that this is a suicide case, and the next step is to open the door and investigate the cause of the deceased's suicide.

Ten minutes later, the locksmith and the landlord also came to the scene, using various tools, to rudely pry open the door.

Gu Chen followed Officer Wang, put on gloves and foot coverings and entered the scene.

The room was a basement of only 20 square meters, the floor was full of beer and cans, and the outside of the garbage basket was scattered with some convenient packaging, and the whole room emitted a foul smell.

And the deceased, with a dagger in his chest, was lying on his back on the bed, and the blood had already stained the bedding red, emitting a fishy smell.

"The deceased was supposed to be a bachelor. Gu Chen put on a mask and continued: "Moreover, I don't pay attention to personal hygiene. ”

"You're right. Officer Wang nodded, he looked at the broken door and said, "This guy plugged in the latch from the inside, does he want to keep himself from being discovered after death? ”

Gu Chen took the initiative to check the situation at the scene, he did not move the body, nor did he wipe the bloodstains, let alone arrange the clothes for the deceased.

Generally, when you come to the scene of the crime, any traces and physical evidence may bring new discoveries.

For example, the blood stains and footprints that may be washed away by the rain should be covered.

If there are injured people at the scene, it is necessary to rescue them in time, but the specific direction of the injured when they are found, including the direction of the head and feet, should be clearly marked.

When protecting various traces and trace substances such as corpses, bloodstains, handprints, footprints, hair, clothing, cigarette butts, paper scraps, excrement, and murder weapons left at the scene, some traces and physical evidence should be marked as warning marks for the sake of conspicuousness.

In order to prevent damage from man-made or natural forces, it can be protected with coverings such as mats, plastic sheets, washbasins, etc., and do not use items with strong odors to avoid damaging the source of smell.

What Gu Chen has to do now is to protect the scene and take photos of suspicious details for evidence.

Subsequently, he patiently waited for the forensic doctor from the technical department of the city bureau to come over and conduct a set of forensic medical evaluations on the deceased.

Officer Wang looked at Gu Chen's professional operation, he didn't say anything, and he couldn't find fault.

Gu Chen's operation is in line with the norms, and he is even more professional than some old policemen.

Officer Wang was glad in his heart, and said in his heart that with Gu Chen by his side, it was indeed quite easy to use.

Ten minutes later......

Forensic Doctor Liu from the Technical Department of the Municipal Bureau came to the scene with his assistant, and after a few brief greetings with Officer Wang, he immediately entered the work state.

"The site is well protected. Forensic Doctor Liu casually praised a few words, which was an affirmation of the cooperation between departments.

Subsequently, Forensic Doctor Liu and his assistants began to use professional instruments to conduct a series of forensic medical evaluations on the deceased.

The general work mainly includes on-site medical investigation, medical follow-up and evidence collection, living medical examination and observation of injuries, autopsy, symptom analysis, test comparison, observation and interrogation, identification of relics, collection and monitoring, special physical examination, etc.

But this also requires specific work to be done on a site-by-site basis, and not everything has to be done.

"Need help?" Gu Chen stood by and watched for a long time, a little idle, so he asked casually.

"No, I'll be fine soon. Forensic Doctor Liu just said casually, but his gaze still did not leave the deceased's head.

The instruments in my hand are very stable and professional.

Officer Wang, who was standing on the side, couldn't help but snicker twice.

Because he didn't expect that Gu Chen, a probationary police officer, would also want to intervene in the work of forensic medicine.

Normally, this kind of disgusting work is avoided by others, but this kid still wants to move forward, and his curiosity is strong enough.

Retracting the tools, Forensic Doctor Liu gave a preliminary conclusion at the scene: "In the oral part of the deceased, I found some residual sleeping pills, and it is obvious that the deceased should have been stabbed with a dagger after taking sleeping pills." ”

"If that's the case, then the deceased was probably killed by him. Based on experience, Officer Wang made a preliminary inference.

Because there is no need for a person who commits suicide with a dagger to take sleeping pills again.

But the question arises again, this room is on the first floor, and it is locked backwards, and the lock with the latch has been inserted, so with only a vent the size of a palm, how did the murderer do it?

"Lao Wang, my work is over. Forensic Doctor Liu took off his gloves, took off one side of his mask and said, "The rest ...... I'll make a death report, and you'll take care of the rest. ”

"Thankfully. Officer Wang thanked him again and again: "I'll let Gu Chen send you." ”

Then he looked to the side and said, "Where is Gu Chen?"
