Chapter 169 The Possibility of Spontaneous Human Combustion
Zhang Yaoming, who was beside Chen Yan, leaned forward and said, "Lan Feng, the case-handling expert of the Dan City Detective Team."
"Lan Feng is responsible for the inspection of the ashes after the three people died.
Lan Feng looked at Chen Yan: "After the case occurred, we immediately conducted a test on the materials left behind by the deceased."
Chen Yan nodded.
In this case, we cannot call for an autopsy.
Because they are all turned into ashes, so what corpses are there?
Click.
Three photos appear on the screen.
"Team Chen, this is a photo of three people leaving ashes at the scene after spontaneous combustion.
“Due to rain erosion, especially the ashes of deceased No. 1’s body, there is very little left.
“We collected more ashes after the deaths of deceased No. 2 Chen Pingping and deceased No. 3 Wu Jianguo.
"The main component of ash is coke.'
"According to the analysis, there is charred ash from burned proteins, carbonized ash from bones, and also char from carbonized fibrous materials.'
Switching to screen projection shows three inspection reports.
"Through the comparative analysis of surveillance videos, we should be able to confirm that the fibrous carbonization left at the scene of the deceased's death should be the carbonization of the clothes and umbrella he was wearing.'
"And this, there are fine metal residues at all three sites."
Click.
The photo switched again: "After testing, it was confirmed that these are debris formed by melting aluminum products and condensing when exposed to water. The specific ingredients include iron, aluminum, etc."
"It should be the impurities produced after the umbrella's frame was burned violently."
'Any other discoveries?'
Although Chen Yan had already surveyed the scene and opened the olfactory gene lock and visual gene lock.
However, since the crime occurred outdoors and it was raining, many traces could no longer be discovered by smell and eyes.
Lan Feng shook his head: "In terms of ashes testing, there are no other findings for the time being.
Ash remnants, it is normal to find nothing about this kind of thing.
No matter what it is, as long as it is carbohydrate, after it is fully burned and finally carbonized, it will form the same thing.
It's just carbon, no other residue.
Chen Yan nodded and looked at the other members of the task force: "If you have any clues or suggestions, please tell me."
"Three weird and bizarre cases of spontaneous combustion surpass our previous knowledge.'
“If you have any questions, ask them.
"Um, Captain Chen, I have a question."
"This is the backbone of the detective team, Liang Ying." Zhang Yaoming introduced Chen Yan from the side.
Chen Yan nodded: "You said, let's have a case analysis meeting, everyone can express their opinions."
"Don't let your hands loose just because I was sent here by the Provincial Detective Brigade."
Chen Yan spread his hands: "Everyone has seen that when I come to Dan City, I am the polished commander.
"In the end, it still depends on everyone to handle the case. Let's work together to solve the case in the shortest possible time."
Liang Ying nodded: "Yes, Captain Chen."
The others looked at each other and nodded.
In fact, what they fear most is that their superiors do not trust them or are dissatisfied with the case handling process.
Chen Yan's arrival is actually to take over Zhang Yaoming's original command position.
However, the good news is that it is just like what Chen Yan said.
Chen Yan was the only one who came to Dan City this time.
In this case, we will definitely have to rely on local detectives in Dan City to form a task force.
In this way, if the case is solved, they will have credit, and if the case is not solved, Chen Yan will support it.
Therefore, everyone welcomed Chen Yan's arrival.
Furthermore, this Chen Yan had just received first-class personal merit.
In the past six months, they have learned about Chen Yan’s notification and awards almost every month.
"Team Chen, my question is about the metal debris at the crime scene.
Liang Ying stood up and pointed to the inspection report on the screen: "According to the inspection results, the debris is the metal residue of aluminum products." However, we know that the melting point of metallic aluminum is more than 660 degrees Celsius. ’
"And at what temperature does the human body burn?"
"The main combustible material in the human body should be fat. Is it possible that the temperature at which this kind of thing burns will melt the umbrella stand? Are there any other questions?
Liang Ying shook her head: "Captain Chen, no more.
'Anyone else, any questions?'
"Team Chen, I have a question. When the three spontaneous combustions occurred, it was raining, but the rain did not extinguish the flames on the three people:
"Team Chen, I also have a question. Even if it is possible for the human body to burn, for example, fat can certainly be burned. However, the bones will be carbonized into ashes, and it will only take about ten minutes. This possibility
One after another, everyone present spoke, mostly with questions.
Since then, everyone has focused on burning corpses.
For example, the burning temperature of corpses.
For example, the problem of how to turn a body into ashes after it is burned.
All in all, all the investigators considered these three natural events to be contrary to existing scientific common sense.
In fact, Chen Yan also thought it was impossible.
This is not a scientific situation at all.
But is there anything that can achieve this purpose?
Before getting the drug cognitive map, Chen Yan's answer would definitely be no.
But just because you don’t know, doesn’t mean you don’t have it.
For example, in the map obtained by Chen Yan, there is a plant called Golden Crow Grass.
This herb is very rare and grows in places where lava flows.
This kind of grass can extract a rare plant essence.
Once injected into the human body, when the amount reaches a certain concentration and external conditions permit, it can cause the body to spontaneously ignite.
Of course, this situation does not apply to the current case of spontaneous combustion of three people.
This is because the external condition that causes spontaneous combustion of Golden Crow Grass is sufficient sunlight.
rainy day
It's impossible.
Therefore, although the case is strange, it is not impossible to achieve.
Half an hour later, Chen Yan looked around: "Does anyone have any other questions?"
Everyone looked at each other and shook their heads.
All the questions that I could think of just now have been answered.
"Okay," Chen Yan stood up and walked to the whiteboard in front of the screen: "I will tell you some questions here.
“First, regarding the issue of spontaneous combustion of the human body.
"Is this possible?
Chen Yan put a check mark on the whiteboard: "I'm telling you clearly that this possibility exists."
Last night, after receiving Qin Chuan's call, Chen Yan did not rest, but stayed up all night
In the early morning, we arranged a vehicle and rushed to Dan City.
This night, Chen Yan was not idle.
He consulted a large amount of information on spontaneous combustion of the human body.
There are many related reports abroad.
“Although the main component of the human body is water, this water does not exist alone.
"There is a lot of fat under the skin of the human body. Under the fat are muscles, fascia and internal organs."
"Among other things, human skin and fat can be burned, as long as the temperature is around 300 degrees, they can be burned.
"As long as fat is burned, the temperature of the flame produced is probably above 800 degrees Celsius."
"At such temperatures, it is theoretically possible to melt the aluminum frame in an umbrella."
"In other words, if the burning of corpses is established, then the theoretical possibility of causing the current scene does exist." Next, there is the fundamental problem. ’
“Why does the human body behave naturally?”
"Here, I will only say one hypothesis: ketosis!"
Ketosis?
Lan Feng was slightly startled: "Diabetes?"
When Chen Yan heard Lan Feng's words, he looked at Lan Feng with slightly surprised eyes.
He is truly a master of handling cases in Dan City.
He just said a term, and Lan Feng not only knew it, but also named most of the diseases that cause ketosis. "Yes, it's diabetes."
"Lan Feng, how do you know this?"
"If you know the specific situation, let me tell you about it."
Chen Yan felt that if Lan Feng knew the specific principles, then he would have greater credibility than what he said. After all, he is a native of the Dan City Detective Team.
As a result, Lan Feng shook his head: "Captain Chen, I don't know the specific situation.'
"She is my old mother-in-law. She has severe diabetes and is accompanied by ketosis, so
oh.
"It doesn't matter, I'll give you a general introduction
