Chapter 170 Umbrella and Shoes

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

"This disease is less likely to occur in humans, but more likely in cattle."

"The main pathology is that there are obstacles in the metabolism of sugar and fat in the human body, so ketone gases, such as acetone, accumulate in the human body.

"Some people have natural fresh breath and aromatic breath. In fact, this may be ketosis. Diabetic patients are more likely to suffer from ketosis because they have obstacles in the decomposition of sugar in their bodies. Ketone gases are flammable and explosive gases. Once they accumulate too much, they may burn.

"In the end, the possibility of spontaneous combustion of the human body is also very high."

This is the first time Chen Yan has held such a case analysis meeting.

It is not analyzing the case, but it feels like a popular science education.

However, this kind of popular science is really indispensable.

All the people who handle the case have no knowledge reserves in this area.

Even some people privately say that this is a ghost story.

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

However, if the detectives handling the case are suspicious, then there is no need to handle the case.

"Of course, this is just one of the possibilities or assumptions."

"Human spontaneous combustion, there is also the candle wick hypothesis, that is, the human body is similar to the candle wick, and the fat is slowly burned under the clothes.

"However, how these three people spontaneously combusted, we still need to unravel the details and investigate. "

"I have told you so much, meaning that there must be scientific basis behind these three cases, but we have not found it yet. '

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

Even Zhang Yaoming secretly breathed a sigh of relief.

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

Some people even have resistance.

However, Zhang Yaoming can't do his job.

How can this thing work.

Say, ah, it's okay, it's just spontaneous combustion, a normal phenomenon!

Don't have any ideological burden.

Who believes that it can be said?

Zhang Yaoming himself doesn't believe it.

Of course, he didn't know whether Chen Yan's statement was true, but at least it sounded possible.

This is easy.

It's only possible in theory, and the rest is practical operation.

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

To be honest, Chen Yan's arrival made Zhang Yaoming feel greatly relieved.

There was a feeling of a heavy burden being lifted off his shoulders: "Captain Chen, you arrange 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 people has been investigated almost the same.

Moreover, Zhang Yaoming's awareness is very good.

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

It is a murder case with a high probability.

However, even if he realized this, Zhang Yaoming still had no way.

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

In other words, this case has exceeded his cognition.

The means and methods of the murderer are no longer in the same dimension as Zhang Yaoming.

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

"Not only that, but the three people also have a common medical history, travel history, work history, etc., which must 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, he must have an internal motive for committing the crime. '

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

Lin Hao, who was sitting next to Zhang Yaoming, nodded.

This morning, after he reported the current work progress to Chen Yan, he had already arranged related work.

"Second, investigate the umbrella!"

Umbrella?

Everyone looked at each other.

Why investigate the umbrella?

"The three people, up to now, have no connection." Chen Yan paused and looked at everyone.

"But the three of them were holding umbrellas on rainy days, which is the most conspicuous common point.

"Captain Chen, I interrupt." Lan Feng raised his hand.

Chen Yan nodded: "You said."

"It is normal to hold an umbrella on a rainy day."

Holding an umbrella on a rainy day, is there anything more abnormal than this?

Not using an umbrella is a problem

"Besides, I have observed the video of the three people self-igniting."

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

Different umbrellas have different styles, colors, and brands

Lan Feng believes that there should be no direction to investigate in this direction.

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

"When the three people self-ignited, it was only on the 19th, the day Li Wei died, that it was drizzling. '

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

"It seems that there is no difference, and the umbrellas used by the three people are all different styles and colors.

"And the brands are different!"

"But 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 Chen Yan said it, they naturally recalled it.

The umbrellas used by the three people are indeed new.

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

"The three are locals in Dan City. Li Wei caught fire on his way home after work.

"Chen Pingping caught fire on his way home after buying vegetables and walking out of the south gate of the farmers' market."

"And Wu Jianguo caught fire on his way home after dinner at his eldest son's house.

"I would like to ask everyone, how often do you change an umbrella in your family?"

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?"

Uh

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

"Everyone, colleagues who bought an umbrella at home during the rainy autumn, raise your hands.

One person!

There were more than 20 people in the meeting room, but only one person raised his hand.

"Actually, my umbrella is not new. I bought it as a gift when I went to the supermarket to buy oil last week.

So!

"What is the possibility 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: "Third, investigate the shoes of the three people."

Click.

The projection switched.

These are three enlarged photos.

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

"There is something wrong with the shoes of the three people!"

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

Operating the projection screen and enlarging the photo, Chen Yan pointed to the heel: "Everyone look here.

"Judging from the marks on the upper of Li Wei's leather shoes, the color is a little faded, and there are slight damages in the folds, so it should be a pair of old leather shoes.

"But everyone, look at the sole of this pair of leather shoes, right foot."

"Did you find anything?'
