Chapter 170： umbrella and shoes

In fact, the so-called ketosis is very simple, it is a series of complications caused by excessive ketone gas in the human body.

"For this kind of disease, the possibility of human beings is relatively low, and the probability of cattle is relatively high."

"The main pathology is the accumulation of ketone gases, such as acetone, in the human body because of the disorder of carbohydrate and fat metabolism in the human body.

"Some people have natural fresh breath and a fragrant smell in their breath. In fact, this may be ketosis. Diabetic patients are more prone to ketones because they have carbohydrate catabolism disorders in their bodies. The ketone gases are all flammable and explosive gases, and once they accumulate too much, they may burn.

"Ultimately, the possibility of causing spontaneous combustion in the human body is also very high."

Chen Yan held such a case analysis meeting for the first time.

I am not analyzing the case, but I feel that I am conducting a popular science education.

However, this kind of science is really essential.

All the people who handle the case have no knowledge reserve in this area at all.

Some people even said in private that it was a ghost story.

Chen Yan doesn't care what the outside world says.

However, if the detectives who are handling the case are suspicious, then the case will not need to go on.

"Of course, this is just one possibility or hypothesis."

"Spontaneous combustion of the human body, as well as the candle wick hypothesis, is that the human body is similar to a candle wick, and the fat is wrapped in clothing and burns slowly.

"However, as to how these three people ignited spontaneously, we still need to dig out the cocoons and investigate."

"I've told you so much, which means that there must be scientific evidence behind these three cases, but we haven't discovered it yet."

After Chen Yan said this, everyone's emotions were obviously different.

Even Zhang Yaoming let out a sigh of relief.

In the past few days, the staff involved in handling the case have been depressed and inefficient.

There are even some people who are against it.

However, Zhang Yaoming couldn't do his job.

How does this thing work.

Said, ah, it's okay, it's just spontaneous combustion, it's normal!

Don't have any ideological baggage.

It can be said, who believes it?

Zhang Yaoming didn't believe it himself.

Of course, he doesn't know if Chen Yan's statement is true, but at least it sounds possible.

This is easy to do.

It's only theoretically possible, the rest is practical.

It's just a matter of how to do it.

To be honest, the arrival of Chen Yan made Zhang Yaoming heave a sigh of relief.

There is a feeling of a heavy burden falling on my shoulders: "Team Chen, you arranged, what is the direction of our next investigation.

In fact, since the first spontaneous combustion case occurred on the 19th, Zhang Yaoming has done a lot of work with the detectives of the Dan City Detective Team.

At least, the basic information between the three of them is almost the same.

Moreover, Zhang Yaoming's consciousness is very good.

After two consecutive cases, that is, after Chen Pingping's death, he realized that this was not a coincidence.

High probability of murder.

However, even if he realized this, Zhang Yaoming still couldn't do anything about it.

Because the case was too weird, he didn't know which direction to break through next.

In other words, this case is beyond his cognition.

The murderer's methods and methods are no longer in the same dimension as Zhang Yaoming.

"First, as I just said, investigate the past medical history of the three people, focusing on whether they have diabetes and its complications.

"Not only that, but also the common medical history, travel history, work history, etc. between the three people should be checked one by one.

"Three people died of spontaneous combustion in succession. There is a high probability that there is some kind of connection behind them. If the murderer really exists, there must be an inherent motive for committing the crime."

"On this point, Deputy Captain Lin Hao will continue to follow up and give a detailed investigation report in the shortest possible time.

Lin Hao, who was sitting beside Zhang Yaoming, nodded.

Early this morning, after he reported the current work progress to Chen Yan, he had already arranged the relevant work.

"Second, investigate the umbrella!"

Umbrella?

Everyone looked at each other.

Why Investigate Umbrellas?

"The three of them have nothing to do with each other until now." Chen Yan paused and looked at everyone.

"However, all three of them are wearing umbrellas on rainy days, and that's the most obvious thing in common.

"Team Chen, let me interrupt." Lan Feng raised his hand.

Chen Yan nodded: "You said."

"It's normal to have an umbrella in the rain."

Is there anything more abnormal than taking an umbrella on a rainy day?

No umbrella, no problem

"Also, I've watched videos of three people igniting spontaneously."

"The umbrella used by Li Wei is black, the umbrella used by Chen Pingping is blue floral, and the umbrella used by Wu Jianguo is blue.

Different umbrellas, different styles, different colors, different brands

Lan Feng believes that there should be nothing to investigate in this direction.

Chen Yan looked at Lan Feng: "Yes, you are right."

"When the three ignited spontaneously, it was only on the 19th, the day Li Wei died, that it rained lightly."

"When Chen Pingping and Wu Jianguo died, it was raining in moderate rain, and most of the people on the road were holding umbrellas.

"There seems to be no difference, and the umbrellas used by the three are all different styles and colors.

"And, the brands are different!"

"However, there is one thing you didn't notice. The umbrellas used by the three people are all brand new."

Brand-new?

Everyone has seen the video, and now that Chen Yan said it, he naturally recalled it.

The umbrella used by three people is indeed new.

The folds folded on three sides are obvious, and even the umbrella used by Li Wei has a trademark on the strap.

"The three of them are natives of Dan City, and Li Wei spontaneously ignited on his way home from get off work.

"Chen Pingping went home from shopping and went out of the south gate of the farmers market to spontaneously ignite."

"And Wu Jianguo, after eating at his eldest son's house, spontaneously ignited on the way home.

"I would like to ask everyone, how often will you change an umbrella at your home?"

This

Including Lan Feng and Zhang Yaoming, they looked at each other.

Chen Yan looked at Lan Feng: "Lan Feng, when was the last time your family bought a new umbrella?"

Forehead

Lan Feng frowned: "It should be two years ago that I don't remember clearly.

"Everyone, it's raining this autumn, and my colleagues who bought umbrellas at home raised their hands.

one person!

There were more than twenty people in the conference room, but only one raised his hand.

"Actually, my umbrella is not a new one. I went to the supermarket to buy oil last week and gave it to me.

so!

"How likely is it that Li Wei, Chen Pingping, and Wu Jianguo bought new umbrellas at the same time?"

"Lan Feng, you are responsible for this matter."

"Yes!" Lan Feng stood up and saluted.

Chen Yan nodded: "The third investigate the shoes of the three people."

Click.

Projection switching.

are three enlarged photos.

"This is a detail I found in the video last night.

"Three people have problems with their shoes!"

"Li Wei was wearing a pair of brown leather shoes that day."

Operating the projection screen, zooming in on the photo, Chen Yan pointed to the heel: "Everyone, look here.

"Li Wei's leather shoes, judging from the traces on the upper, the color is a little faded, and the folds are slightly damaged, so it should be a pair of old leather shoes.

"But, everyone, look at the soles of these leather shoes, right foot."

"Have you found anything?"
