Chapter 568 Crime Scene
Zhang Yaoming saw the change in Chen Yan's expression.
Zhang Yaoming smiled bitterly and handed Chen Yan a piece of on-site survey information.
"Team Leader Chen, don't tell me about this incident. I was on the scene at the time, and I don't believe it either."
He was stabbed 32 times and committed suicide...
I'm afraid no one would dare to write this kind of story like this.
Suicide, generally speaking, no matter what the purpose of the deceased is, he wants to end his life. However, due to the subconscious self-protection mechanism of the human body, when committing suicide, the suicidal person will most likely choose 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 times, a suicide method similar to that of Ling Chi...
No wonder Zhang Yaoming reported the case to the Liao Provincial Detective Brigade.
Even if Chen Yan encounters this kind of thing, he may not be able to handle it. He has to check it repeatedly. Opening the file, Chen Yan read through 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 found no traces of anyone else committing the crime at the scene, no footprints, no fingerprints, no skin scraps, no hair, nothing."
"The 32 stab wounds on the deceased's body were all within reach of the deceased's right hand."
"And many of the stab wounds were probing wounds. In addition, there is surveillance video in the corridor where the deceased lived. It can be determined that no outsiders entered the deceased's home before her mother entered."
"So, we initially determined that the deceased committed suicide."
Zhang Yaoming's words were very simple, but actually revealed a sense of helplessness. He concluded that the deceased committed suicide because no trace of outsiders was found at the scene.
The deceased Wang Luyao, 36 years old, and her husband were on a business trip three days ago and are still in Shen City. Her mother called Wang Luyao this morning but did not get through. She was afraid that something had happened to her daughter, so she went to look for her at home. Wang Luyao's mother entered Wang Luyao's community at 7:54 this morning, as the surveillance video can prove.
Because the old man had the key to Wang Luyao's house, he opened the door at 7:59 and then called the police. At 8:11, Zhang Yaoming led the team to the scene.
After that, after two hours of on-site investigation and surveillance video investigation and evidence collection, it was initially determined that the deceased committed suicide.
However, because there were too many stab wounds on the deceased's body, Zhang Yaoming chose to report the case and requested the crime squad 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 files, the judgment of the Dan City Detective Team 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 based on the injuries on the corpse and traces on the scene.
For example, wounds are classified in great detail during on-site investigation and appraisal.
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 wounds, closed wounds, etc.
Each type of wound has different characteristics. Combined with blood trace analysis, many details of the injury to the deceased can be determined.
As for the traces of outsiders at the scene, this is better judged.
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 are found.
Chen Yan still has to go to the scene to finalize the specific situation.
The car drove very fast and arrived at the crime scene in less than twenty minutes after getting off the highway.
A cordon has been set up on the floor where the crime occurred. After stepping out of the elevator, Chen Yan saw that many detectives were still working.
Detectives are also investigating and visiting the deceased's neighbors.
"Has the time of death been determined?"
Zhang Yaoming nodded: "It's confirmed, it was 3 o'clock this morning. The cause of death was shock caused by excessive blood loss."
It’s 3 o’clock in the morning, so it’s already been 10 hours.
During this time, 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 time.
Early cadaveric phenomena generally refer to the cadaveric changes that occur in the human body within 24 hours after death.
The door was already open, and Chen Yan observed it before entering.
The inside and outside of the door are relatively clean, there is no dust, and there are no obvious scratches on the lock.
In other words, the door should not have been damaged.
The moment he walked in, Chen Yan glanced at the cat's eyes.
When the visual gene lock is on, every detail on the cat's eyes is presented in Chen Yan's mind.
There is dust in the gap, there are no scratches around the cat's eye, and there are no signs of prying.
The anti-theft door used in the deceased's house was an ordinary mechanical lock. Chen Yan, who had received system rewards for specializing in unlocking skills, was very familiar with the technical opening of these doors.
In addition to violently destroying door locks, most technical unlocking methods are to open the peephole, and then use a relatively specially shaped wire to hook the door handle inside, and the door will be opened.
But from now on, there are no signs of the peephole being pried. In other words, without considering surveillance, if there is a murderer, 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 come into view.
On the edge of the sofa, a body covered in blood was leaning on the sofa.
There was a lot of sprayed blood around, the sofa seemed to be soaked in blood, and there was also a pool of blood on the floor.
Generally speaking, the blood volume of adult men is 5 to 6 liters, and the blood volume of adult women is 4 to 5 liters.
Although not all the blood in the deceased's body had flowed out, judging from the situation at the scene, at least two-thirds had been drained.
Putting on shoe covers and gloves, Chen Yan walked into the room and observed carefully.
At this time, the on-site investigation of the room where the deceased lived had been completed, and the only person who followed Chen Yan in was Zhang Yaoming, captain of the Dan City Detective Team.
Zhang Yaoming, who had cooperated with Chen Yan, knew Chen Yan's handling style very well. When the other party inspected the scene, Zhang Yaoming followed Chen Yan quietly without saying a word.
Immediately, Chen Yan opened the olfactory gene lock and the visual gene lock.
The smell in the room was very mixed.
But the strongest smell was that of the dead man in front of me, and there was another person whose smell was as strong as the dead man.
It should be the other person's husband.
"Has the deceased's husband returned?"
"He has returned, and he and the mother of the deceased are now in the team for questioning."
Chen Yan nodded.
If one party of a married couple dies, judging from Chen Yan's experience in handling cases, the other party is most likely to be suspect.
But this case is obviously not the case. Wang Luyao's husband has been on a business trip in Shen City. There is a witness there. He just got the call this morning and rushed back from Shen City.
"The deceased's husband is Zhao Guang, 37 years old, an engineer. We have investigated his whereabouts in the past few days. It is true that he was on a business trip in Shen City and has never been back. There are colleagues who work and live with him there. Can testify."
Obviously, Zhang Yaoming has already done this work in advance.
"Have you ever come into contact with this Zhao Guang?"
Zhang Yaoming nodded: "I have been in contact with him, and the other party reacted very strongly to Wang Luyao's death."
"Zhao Guang firmly believes that the deceased Wang Luyao could not have committed suicide."
