Chapter 569 It Was Really Suicide! (Big Chapter Asking for Votes)

"Why?"

"Zhao Guang said that Wang Luyao had a WeChat video chat with him the night before yesterday, saying that she would go traveling when he came back."

"Furthermore, according to Zhao Guang, Wang Luyao's job is relatively stable, the relationship between the two of them is relatively good, and nothing special has happened recently."

"Wang Luyao had no reason to commit suicide."

"That's one of the reasons why we report the case."

Suicide usually occurs when one is full of disappointment in the current life, or when there are some major changes.

Either mental illness or depression will lead to suicide.

Otherwise, how could a good-looking person choose to commit suicide?

"Did the deceased engage in any intimate behavior during his lifetime?"

"No, the detective in charge of the autopsy has checked and found that the deceased had no intimate behavior before his death." Chen Yan nodded and continued to observe the condition of the corpse.

The body had been dead for more than 10 hours and was now in the stage of rigor mortis.

There is a medical order of human death. Generally speaking, as long as certain organs have not suffered a particularly heavy blow, the order of death is the brain, internal organs, and muscles.

Even the real death of internal organs is in order. Now the heart, spleen, liver...

The last thing to die is the muscle group. Some individuals may even have a trembling reflex in their muscles a few hours after death.

Most corpses undergo very regular changes after death.

Under normal circumstances, the corpse will show muscle relaxation about an hour after death, usually no more than two hours.

This process is relatively short. The deceased's muscle tone will disappear and the muscles will become soft shortly after death.

This process is very important during the autopsy process.

Because it is precisely because of this process that the elasticity of the surface of the corpse, especially the skin and muscles, disappears, and some heavy objects press the entity, causing special marks.

And the weight of the object does not need to be too heavy. Even rings, necklaces, and watches will leave traces. Such traces were not visible at the time, but with the appearance of rigor mortis, the traces will become increasingly clear.

These traces can be used to determine whether the body has moved after death.

The body on the sofa was dressed in home clothes. A sharp knife fell to the ground and was infected with blood.

There were multiple stab wounds on the deceased's body, his home clothes had been torn to pieces, and there were blood stains everywhere.

The locations of the stab wounds were accurately marked and were within reach of the deceased's right hand. In other words, if the deceased really committed suicide, he would have been able to cause these stab wounds.

Putting on gloves, Chen Yan opened the wound on the deceased's right arm and looked carefully.

The wound was everted and the blood stains were obvious, but the wound was relatively shallow and was a relatively obvious probing wound.

Based on the size of the wound, it can be determined that it was caused by a single-edged knife, which is consistent with the shape of the knife at the deceased's feet.

The same goes for several other wounds.

"The fatal injury was the stab wound in the abdomen. The wound was extremely deep and pierced the spleen, eventually leading to death from excessive blood loss."

Zhang Yaoming reported the investigation results of the Dan City Detective Team behind Chen Yan.

Chen Yan pushed aside the clothes on the abdomen of the corpse, and a severe stab wound was clearly visible.

This is exactly what Zhang Yaoming said was the fatal stab wound.

Afterwards, Chen Yan examined the deceased's 32 stab wounds one by one, and found that there were no wounds left in any of them.

In summary, the deceased was stabbed in 4 places in the abdomen, 2 in the left wrist, 8 in the forearm, and 3 in the upper arm.

There were also stab wounds on the inner and outer sides of both legs, 11 in total, 5 on the left leg and 6 on the right leg.

There were four stab wounds on the chest, 2 on the left chest and 2 on the right chest.

In total, there are 32 places in total.

The fatal injury was just like Zhang Yaoming said, a puncture wound in the abdomen.

Standing up, Chen Yan didn't frown.

suicide……

Generally speaking, it is the courage that is most needed.

Because when people end their own lives, it is actually a confrontation between reason and instinct.

In nature, humans are the only animals that commit suicide as adults.

Among animals that live alone in nature, no animal has suicidal behavior. Among animals that live in groups, only old and sick animals will die unless there is a shortage of food.

But in this case, it is for the sake of racial continuation, and this situation only exists for certain animal species.

Humans have the highest suicide rate among all animals.

The reason is that people have wisdom and reason can suppress the instinct of survival.

Never think that committing suicide is a simple matter.

Wanting to die is not easy sometimes.

Chen Yan has seen too many examples of unsuccessful suicides.

In his previous life, Chen Yan had seen someone commit suicide by drinking pesticide, but after he was discovered, he recovered after his stomach was washed. Some people cut their own necks with a knife in order to commit suicide. Their necks were almost broken, but they did not die because they did not cut off their carotid arteries.

Even the throat and trachea were severed, and one-third of the cervical vertebrae were severed, but the person did not die. There was also suicide by cutting the wrists, but the exact location of the arteries could not be found, the wrists were almost cut off, and the person was not dead.

It can be seen how tenacious human vitality is.

Some people will say, doesn’t it hurt after death after suicide?

In fact, under a certain stress response, the human body may not feel pain.

Even, under the stimulation of pain, suicidal people want to end their own lives even more, so they will do more crazy things.

However, there was always something wrong with Chen Yan's scars on Wang Luyao's body.

Judging from the way Wang Luyao sought death and the final result of her death, Wang Luyao wanted to end her life with a knife.

Wang Luyao, 36 years old, graduated with a bachelor's degree and received a good higher education.

It is impossible for such a person not to know how to end his life with a knife. The quickest way is to cut his wrists or wipe his neck.

This is also the first method of suicide that normal people think of.

But on Wang Luyao's body, there were no scars near her neck.

The wound on the wrist was even stranger.

There were two stab wounds on the left wrist, but not on the right wrist.

This is strange. She can think of cutting her left wrist, but not her right wrist? The blood marks on the murder weapon on the ground were very obvious. It could be seen at a glance that Wang Luyao was holding the knife in her right hand during the entire suicide process.

At first glance, there seems to be no problem, but don't forget that Wang Luyao is a weak woman, and her physical strength is not very strong after being injured.

After cutting himself 31 times, did he still have the strength to stab himself in the abdomen, causing a nearly penetrating wound, leading to his death?

Even if there is, can Wang Luyao do it with one hand holding a knife?

Chen Yan walked to the other side of the sofa where Wang Luyao was reclining and sat on the sofa as well.

Holding the mobile phone in his hand, he gestured at the wounds on Wang Luyao's body.

It's like I'm cutting myself with a knife.

Zhang Yaoming naturally knew what Chen Yan was doing.

Restore the process of Wang Luyao's suicide.

In fact, judging from the situation at the scene, there is indeed no trace of outsiders entering.

Because Wang Luyao had 32 stab wounds on her body, all of which were caused on the sofa in the living room, and there were traces of her blood everywhere near the sofa.

From the perspective of blood trace analysis, these blood sprays are naturally formed.

They have done simulations and there is really no possibility of discovering outsiders.

Because, for the same wound, if it is scratched by oneself and scratched by others, the angles are different, and the direction of blood injection will be different.

If it was really a homicide, to be honest, Zhang Yaoming really couldn't think of anything else except ghosts.

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

For nearly half an hour, Chen Yan sat next to Wang Luyao's body and kept imitating the process of Wang Luyao's wound formation.

However, after half an hour of simulation, all 32 stab wounds were simulated, and no doubts were still found.

Every stab wound was natural. Judging from the stab wounds on the left wrist and the inside and outside of both legs, Wang Luyao should have committed suicide in a sitting position.

Because some cuts are curved, they can only be done in a sitting position.

Moreover, Chen Yan's simulation also confirmed the judgment of the on-site investigators of the Dan City Detective Team that all stab wounds were within reach of the deceased's right hand, and there was no situation where joint conversion was impossible.

In other words, each of these stab wounds could easily be done by Wang Luyao in this sitting posture.

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 penetration 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 jet, a blank area will be left. For example, if the murderer likes to move in the space, he 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 committed homicide.

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

There are two types of autopsy. 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 some 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 presented, so further examination is required.

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

Zhang Yaoming was slightly stunned. He didn't know that Chen Yan was proficient in this, but he still nodded. Soon, the detective responsible for 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 occurs after the muscles relax, starting from the small joints and gradually spreading to the large joints. Rigor mortis reaches its peak state 24 hours after death.

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, and the body will become loose again, and the whole body will be 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 death, rigor mortis will reappear soon after.

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

And 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 things are arranged very neatly.

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

There is a bowl next to it.

Seeing this, Chen Yan frowned even more tightly.

A person who is preparing to commit suicide will 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?

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.

Because of rigor mortis, Wang Luyao's body was 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 anything wrong with 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 deceased's back after Chen Yan had lifted up his clothes. Like Chen Yan, he was astonished.

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

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 the back of his home clothes, and took a closer look.

Then he unzipped 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.

"There is no one entering or leaving the video. Could it be that the other party is invisible?"
