Chapter 168： black ashes

Three bizarre human self-immolations, and it was on a rainy day.

The head, limbs, and torso were all burned to ashes.

how can that be?

There has always been a legend about the spontaneous combustion of the human body.

Especially in foreign countries, relevant reports have always existed.

However, this is the first time for Chen Yan to have actually seen the spontaneous combustion of the human body, and even has video evidence.

When the three spontaneously ignited, it was raining.

After the deceased was burned, the ashes were washed away by the rain. When Zhang Yaoming and the others arrived at the scene, there was basically nothing to investigate.

Especially Li Wei's natural scene.

At the entrance of the funeral home, next to the main road is a gravel road, and Li Wei was walking on this small gravel road at the time.

The rain washed away, and the ashes after the burning body had been washed away.

Only some dark stains remained on the scene.

The location of the spontaneous combustion of Chen Pingping and Wu Jianguo was discovered early because there were witnesses, but the crime scene was preserved.

Huimin Farmers Market.

The South Gate, an area close to the left, has been isolated.

Zhang Yaoming accompanied Chen Yan: "Captain Chen, this position is the scene of Chen Pingping's spontaneous combustion."

On site, a small shed constructed of waterproof plastic.

Outside, a detective is watching.

Seeing Zhang Yaoming coming, he immediately pulled away the plastic sheet.

Entering the small shed, what caught Chen Yan's eyes was a pool of black stains.

"At that time, it was raining, and the rain was relatively heavy.

Zhang Yaoming began to introduce the situation.

"Because this is the second case of spontaneous combustion, I came to the scene immediately.

Zhang Yaoming pointed to the stains on the ground: "This is the ashes left after Chen Pingping spontaneously combusted."

"When we came, Chen Pingping's body was completely reduced to ashes, and it didn't continue to burn."

At this moment, Chen Yan squatted down and observed carefully while listening to Zhang Yaoming's report.

Chen Yan put on gloves, gently rolled up the black stain on the ground, and put it on the tip of his nose.

At the same time, the olfactory gene lock is turned on, and the visual gene lock is turned on.

There is a distinctive smell of protein charring in the ashes.

There is also a pungent smell of burnt and carbonized plastic.

After that, nothing else.

After the visual gene lock was turned on, there was basically nothing to be found.

Ashes on the ground, a unique form of carbonized matter

And, because it was washed away by the rain, a part of the ash adhered together, forming black particle lumps.

In addition, there are some fine particles, similar to the small beads that condense after the metal is melted and pre-cooled.

"Did the heavy rain at that time have any effect on the fire that burned the body?"

"According to witnesses at the time, Cheng Pingping was holding an umbrella at the time.

"Originally, Chen Pingping came here with the neighbors to buy vegetables, and then walked out of the market with the crowd.

"At that time, the two were chatting, but the neighbors said that they suddenly felt a high temperature around them.

"Then, when the neighbor was about to look at her, a flame suddenly ignited on Chen Pingping's body."

"Within a few minutes, even with her umbrella, she was up.

"Although it was raining heavily, the fire was getting bigger and bigger."

"In less than ten minutes, there is only a piece of debris left."

Chen Yan has seen the whole process in the video.

It felt incredible at the time.

Now, after Zhao Yaoming explained it in detail again, Chen Yan felt even more nonsense.

Yes, it's bullshit.

You know, Chen Pingping was holding an umbrella at that time.

The ribs of umbrellas are all metal structures, usually aluminum products.

That's why there are some fine metal beads on the ground.

However, what is Lu's melting point?

660 degrees Celsius!

What is this concept?

The temperature of the flame of an ordinary lighter is less than 500 degrees Celsius.

The flame temperature is above 660 degrees Celsius, and only the fire is in daily contact.

Moreover, it is still the most prosperous fire.

According to the video record, there is also the situation that Zhang Yaoming learned at the scene.

Cheng Pingping ignited spontaneously in just ten minutes.

The fire was huge, and the rain couldn't put it out.

"Have the results of the test on the ashes of the corpse come out?"

Zhang Yaoming nodded: "It's already out."

"The composition of the ash is a mixture of coke, some scraps of aluminum and iron, and no other chemicals were found." Chen Yan frowned.

Zhang Yaoming and the others obviously thought of some possible situations.

For example, is it some chemical substances that cause the human body to burn?

However, no chemicals remained in the ash.

In that case, there are only two possibilities.

Either, it has nothing to do with chemicals, or, even if all the substances are burned when they are burned, no traces are left.

Second scene.

The site where Wu Jianguo ignited spontaneously was on a sidewalk.

The same has been covered by a small shed.

The relevant situation is exactly the same as the scene of Chen Pingping's death.

Only the remaining ash remains, some of which stick together after being washed away by the rain.

Returning to the Dan City Detective Team, Chen Yan said nothing.

this situation

Chen Yan had never experienced it.

No clue at all.

The most important thing is, how did these three people burn?

70% of the human body is actually water.

Even if it is cremated, the cremation furnace of the funeral home does not simply push people in and it burns.

The process is relatively complicated.

There are some institutions in the crematorium

After the corpse enters, there will be sharp claws, which will scratch the corpse to smash the corpse, so as to avoid the sudden change of the internal and external pressure of the corpse during the burning process, causing an explosion.

The flame used for incineration is also a mixed flame of high temperature, high heat and high pressure.

Ensuring that the body is fully incinerated.

Moreover, at the end of the incineration, there is a mechanical pressing plate rolling, so that some large bones, such as skulls, teeth, hip bones, etc., can be crushed into slag.

In the end, it is the ashes we see.

Let's just say, in order to turn the corpse into ashes, the funeral home still took a lot of thought.

The crematorium can also be regarded as a technological product.

Because, in the past, this kind of work was done manually.

Using props, cut the corpse up, burn it, and break the larger bones with a hammer.

As a result, the three were fine.

On a rainy day, it is directly gray.

This is very similar to the vampire in the movie, after being irradiated by the sun, it is an effect.

Because of this, Qinchuan immediately sent Chen Yan to Dan City to organize the investigation and handling of the case.

Case analysis meeting.

For the first time, Chen Yan presided over the analysis of the case of self-immolation in the rain.

Click.

The projection screen is a photo of the three dead.

"Li Wei, Chen Pingping, Wu Jianguo, three people."

"According to the currently known information, there is no obvious relationship between the three."

"They don't know each other, and their occupations are very different. There is no intersection, and they don't have common friends." "Vice captain Lin Hao is still investigating the deeper relationship between the three."

"Next, what we need to focus on is to find out what caused the three people to spontaneously ignite.

"Three people, one after another in a short rainy day, suddenly spontaneously ignited, the probability of accident and coincidence is very low."

"Then, if it was murder, why did the other party do it, and how did he do it?'

Zhang Yaoming and others nodded.

unexpected possibility

Or the possibility of a coincidence is really unlikely.

Spontaneous combustion is a non-existent thing.

Now there are three people in a row, how is this possible?

Therefore, the possibility of three people dying of murder is very high.

Since there is a high probability of murder, here comes the problem.

Why did the killer murder these three people?

for money?

The three of them are all burnt to slag, where can I get the money?

Moreover, among the three, Li Wei is only an ordinary employee of the funeral home, and Chen Pingping is only a head nurse of the First Hospital. Both are ordinary people without much savings.

On the other hand, Wu Jianguo had worked in engineering and accumulated some capital when he was young.

But if it's for money, there's no need to burn people into scum.

As for the murder

Not very likely.

The three Wu Jianguo are 60 years old.

Li Wei is 56 years old and Chen Pingping is 55 years old.

At this age, emotional entanglements are unlikely to occur.

"So, the possibility of vendetta is our focus."

"On this point, we will be doing research after Vice Captain Lin Hao's investigation comes out."

"Now, our focus is to find out how the other party allowed these three to spontaneously ignite."

Chen Yan's voice fell, and the atmosphere in the conference room suddenly solidified.

No way, we really don't understand.

Spontaneous combustion is enough, or spontaneous combustion when it rains heavily.

Isn't this bullshit.

Besides, if you pour gasoline on a person and set it on fire, he won't turn into ashes in the end.

"Team Chen," said a middle-aged man, sitting in Zhang Yaoming's hands: "My name is Lan Feng, the captain of the first division of the Dan City Detective Team.

"Let me tell you the situation
