Chapter 421 Site Survey

Maggots do not breed naturally.

In general, the so-called maggots are actually fly maggots.

After a person dies, if there are flies around.

They will lay eggs on the surface of the body.

Then maggots will form.

They like to suck liquid food.

After a person dies, a large amount of liquid will form in the abdomen due to decay.

The muscles of the limbs decay slowly, so the number of maggots will be relatively small.

As for the sizzling sound...

It should be the sound made by the maggots rubbing against each other when they wriggle.

Because the skin on the surface of the corpse is relatively fragile, Chen Yan did not continue to press, but observed carefully.

The whole body was lying on its back in the bathtub. Because it was full of maggots, only the arms were exposed except for the head.

Other places were buried by maggots and could not be seen.

The head was resting on the faucet of the bathtub, and brown marks could be seen on the back of the head.

It should be the head of the deceased that hit the faucet, causing hemorrhage in the back of the brain.

As for whether this is the cause of death, it will be confirmed after the autopsy.

And the arm...

On the left wrist of the deceased, a watch can be vaguely seen.

However, due to the gigantism, most of it has been covered by swollen skin.

A deep strangle mark has been formed.

It is like a long balloon, strangled at one end, forming two lotus root-like shapes.

Weird, terrifying.

After the fingers swelled, maggots crawled under the skin.

Li Hong and Yang Wanshu retched again.

Turned his head away and took two steps back.

Chen Yan kept staring at the watch.

Judging from the various signs at the crime scene, the deceased was most likely to have died accidentally.

While the deceased was taking a bath, the back of his head hit the faucet because the bathtub was slippery.

Where did he die?

This was the first judgment Chen Yan made after observing the body.

However, the watch on the wrist of the corpse made Chen Yan a little confused.

Bathing with a watch?

Of course it is not impossible.

Swimming outdoors, especially in an open-air swimming pool or in the wild.

It is common to wear a waterproof watch to swim.

Now, most watches on the market are waterproof.

Some watches also have a guide function, which can help the wearer identify directions in the wild or underwater.

However, wearing a watch while bathing in the bathtub at home...

Most people would not do this.

Because the corpses were buried in the bathtub by maggots, and the information exposed on the surface was probably this information.

Chen Yan gritted his teeth and turned on the olfactory gene lock.

Boom!

The fierce corpse stench, like the claws of the devil, strangled Chen Yan's brain along his nasal cavity.

A fierce dizziness followed.

Chen Yan suddenly felt suffocated and lacked oxygen.

And this feeling continued, and the fierce corpse stench seemed to suppress all other smells.

After a while, Chen Yan turned off the olfactory gene lock.

After a long breath of turbid air, Chen Yan looked at Wang Hu.

"How many people entered the scene after the crime?"

"Only six people."

"The two detectives who went out on duty are now on guard downstairs."

"Then there are me and Deputy Captain Wang Sheng, and the two detectives who just went out to investigate the scene."

Six people.

Chen Yan frowned slightly.

When Chen Yan just entered the bathroom, he passed by the sink.

There were two toothbrush holders neatly placed on it.

One was pink and the other was navy blue.

Moreover, the bristles of the toothbrush that was placed upside down were slightly prostrated, which obviously meant that someone used it frequently.

Because of the giant view, although Chen Yan could not tell the specific age of the deceased for the time being, from the fact that the deceased could afford to live in the Imperial Family Community.

His financial ability was obviously not bad.

After all, even if he rented a house here, it would cost four or five thousand yuan a month.

And the two-colored toothbrush holders on the sink meant that the deceased was either married or had a girlfriend who lived together.

However, Chen Yan found at least seven kinds of smells in this room.

In addition to the six people Wang Hu mentioned, excluding Chen Yan, Li Hong, and Yang Wanshu, there are seven more smells.

However, due to the cover and interference of the corpse odor, Chen Yan could not tell how long these smells lasted.

Some of them were also difficult to distinguish clearly.

"Call the two detectives who just did the investigation."

"Yes!"

Wang Hu nodded and turned to go out.

"Team leader Chen, this is Zhang Tao, this is Chen Yu, they have been doing the on-site investigation just now."

Chen Yan nodded and looked at the two Zhang Taos whose faces were obviously pale: "What did you find?"

Zhang Tao saw Chen Yan looking at him and immediately perked up: "Report to the leader."

"Because the body is covered with maggots and the skin on the surface of the body is very fragile, we did not conduct too much investigation on the body."

"Before you came, we mainly collected traces in the room."

"In the room, we found fingerprints of six people."

"Among them, two people should have lived here for a long time."

"The other four should just come here as guests."

"Why do you say that?"

At this time, Chen Yu stepped forward: "Report to the leader, because we collected two fingerprints on the toothbrush holder on the sink."

"And these two fingerprints were also found in the bedroom, bathroom and kitchen."

"But for the other four fingerprints, we only detected them on the coffee table and sofa in the living room."

"From the size of the fingerprints, we can also tell that they are two adults and two children."

"By the way, two children's fingerprints were found in the bathroom."

Chen Yan nodded.

The fingerprints of adults and those of minors are different in size, so they are easier to distinguish.

Zhang Tao and Chen Yu were able to collect fingerprints, indicating that these four people should have visited this house in a short period of time.

"Is there anything else, such as the time of death of the deceased?"

Zhang Tao and Chen Yu looked at each other.

Zhang Tao shook his head: "When we entered the crime scene, the indoor temperature was very high, probably more than 30 degrees."

"The body is highly susceptible to decomposition at these temperatures."

"And now that the corpse has a giant appearance, it is difficult to accurately judge the time of death."

"This requires an autopsy to be finalized."

Chen Yan nodded.

Determining the time of death of the deceased is mostly based on the degree of rigor mortis and the color of the body spots.

However, the corpse where the giant view appeared was highly decomposed.

It is no longer possible to judge the time of death through rigor mortis and cadaveric plaques.

However, Chen Yan received the autopsy skill specialization rewarded by the system.

The time of death can also be determined by comparing the degree of decay of the corpse at different temperatures and even some characteristics of the giant view, such as the fragility of the skin after the head is swollen.

According to Chen Yan's observation, the deceased should have actually died 10 days ago.

The growth cycle of this maggot is also relatively consistent.

There are several different stages in the growth of fly larvae.

From eggs to hatching into larvae, which then turn into cocoons.

Emerges from the cocoon and becomes an adult fly.

This time is usually around 14 to 15 days.

The maggots in the bathtub are at their most fertile now.

It is already the mature form of a larva.

In a day or two, it should turn into a cocoon.

Therefore, judging from this aspect, the time of death of the deceased should be about 10 days.

"In this case, get the body back first."

"Zhang Tao and Chen Yu, the three of us are together."

Chen Yan didn't look at Li Hong and Yang Wanshu at all.

Forget it about Wang Hu and Wang Sheng.

After all, they don't specialize in this.

It's unprofessional to do this.
