After the simulation was completed, Chen Yan carefully observed the shape of the blood spray at the scene.

No big problem.

There are obstructions on the left and right, and the blood spray is consistent with the shape of the wound.

There were 32 stab wounds on Wang Luyao's body, including stab wounds, scratches, and even close to penetrating wounds. The traces of blood spurting or flowing from different wounds are actually different.

Chen Yan matched the traces of blood flowing or spurting from the wounds one by one, ruling out the possibility of other people at the scene.

A crime scene like this may seem messy, but it is actually the easiest place to detect the traces left by the murderer.

For example, if the murderer's body blocks the blood spray, it will leave a blank area. For example, if the murderer likes to move in the space, it will leave footprints, etc.

Sometimes, if the murderer blocks the spray of blood from the deceased's wound, the height and weight of the murderer can even be determined through blood trace analysis.

But nothing was found at Wang Luyao's death scene.

Except for the traces left by Chen Yan and others, there is no evidence that anyone else existed.

Is it really suicide?

"In this case, take the body back for autopsy first."

Zhang Yaoming nodded: "Okay, I'll make arrangements right now."

Autopsies are not required for all deaths.

Such as natural death, accidental death, death from illness or suicide.

None of these require an autopsy.

An autopsy will only be conducted if the detective suspects that the other party may have been murdered.

Of course, the autopsy mentioned in Chen Yan refers to the dissection of a corpse.

There are two types of autopsies. One is the autopsy, which Chen Yan just did.

The other is autopsy.

Chen Yan wanted to determine through autopsy whether the other party was still poisoned, and there were other conditions that needed to be determined.

There are only 11 hours left before the death of the deceased. This time period belongs to the early corpse phenomenon stage of the corpse.

At this stage, many features of the corpse have not yet been fully demonstrated, so further inspection is required.

"Captain Zhang, please make arrangements. I want to participate in this autopsy."

Zhang Yaoming was slightly startled. He didn't know that Chen Yan was proficient in this, but he still nodded. Soon, the detective in charge of on-site investigation came in carrying a stretcher.

Because the body was lying sideways on the sofa, the body was bent at about 70 degrees due to rigor mortis.

Several people came forward to lift the body off the sofa, but did not destroy the rigor mortis.

In fact, rigor mortis is difficult to destroy.

Rigor mortis appears after muscle relaxation, starting from small joints and gradually spreading to large joints. Rigor mortis reaches its strongest state 24 hours after the death of the deceased.

At this time, all the joints of the corpse were locked, and the entire corpse was like a steel plate.

After that, the rigor mortis gradually begins to relax. In another 48 hours, the rigor mortis will gradually disappear, the body will become loose again, and the whole body will become soft.

Of course, rigor mortis is not indestructible.

However, the process of destroying rigor mortis at different times has different consequences.

Generally speaking, if rigor mortis is forcibly destroyed within 6 hours after the death of a human body, rigor mortis will reappear soon after.

However, the intensity of rigor mortis after recovery will be weakened.

If it is destroyed after 6 hours, rigor mortis will not reoccur.

As for the principle of rigor mortis, there is currently no final conclusion.

But judging from the cause, it is because after the human body dies, muscle activity disappears, and joint stiffness is caused by tight contraction.

While several people were moving the body, Chen Yan carefully observed the layout of the room.

It's very clean, which is Chen Yan's first impression.

Except for the blood stains in the living room, the rest of Wang Luyao's home can be said to be spotless. It is very clean and everything is arranged very neatly.

The kitchen utensils in the kitchen were arranged in an orderly manner, and a clay pot was placed on the stove. Chen Yan opened it and saw that there was black-bone chicken soup inside.

There is also a bowl placed next to it.

Seeing this, Chen Yan frowned even more tightly.

A person who is preparing to commit suicide would still make black chicken soup?

The kitchen is connected to a small storage room, which contains a washing machine and some sundries. The washing machine has stopped running, but there is a flashing red indicator light on the crystal panel.

Chen Yan opened the washing machine, and sure enough, there were already washed clothes inside.

unreasonable!

Not logical!

If a person commits suicide, he will definitely go through a very complicated inner struggle.

But before committing suicide, Wang Luyao not only cooked black-bone chicken soup, but also washed her clothes in the washing machine?

After walking out of the kitchen, several on-site investigation investigators had just transferred the body to the stretcher. Chen Yan glanced at it and was about to turn around and go to the bedroom and bathroom to take a look.

Suddenly, the scene in Chen Yan's mind flashed again.

Something's wrong!

"etc!"

Chen Yan turned around and walked quickly to the stretcher carried by several people.

Several detectives heard Chen Yan's voice and immediately stopped: "Team Leader Chen, what's wrong?"

Zhang Yaoming also stepped forward: "Team Leader Chen"

Chen Yan waved his hand and walked directly to the stretcher.

Due to rigor mortis, Wang Luyao's body is now lying sideways on the stretcher, facing Chen Yan's back.

Chen Yan lifted up the house clothes on the corpse and his pupils shrank.

The deceased's back developed dark red scars due to the compression of his own weight during the process of rigor mortis.

Chen Yan didn't move the body when he inspected it just now, so he didn't find any damage to the back.

Just now when several detectives were carrying the body, the housecoat on the back of the deceased was lifted up. When Chen Yan turned around, he saw it.

Zhang Yaoming also saw the back of the deceased whose clothes had been lifted up by Chen Yan, and was as surprised as Chen Yan.

Zhang Yaoming is not a fool. He can become the captain of the Dan City Detective Team and has very rich on-site experience.

With just one glance, he discovered that the marks on the body's back were not in the right color!

Chen Yan observed carefully, completely lifted his home uniform from his back, and took a closer look.

Then he opened his trousers and found two darker indentations on the inner thighs of the corpse.

"This trace..."

Chen Yan looked at the sofa where Wang Luyao had sat and knew where this mark came from.

"Wang Luyao once sat on a person before she died."

"That's why such corpse spots are formed!"

Sitting on someone?

Zhang Yaoming's expression changed rapidly: "This... is impossible!"

There is a reason for Zhang Yaoming's surprise.

They have checked the video in the corridor and found that no one entered Wang Luyao's home last night.
Chapter completed!
