Seeing that everyone was thinking, Bai Song then began to express his opinion: "After Li Yanan ran away, Zheng Xiaowu went back to his residence, wanting to come back at night and find a way to take the money away.

I now speculate that she also died in an accident.

This thing sounds very, but if you take into account Zheng Xiaowu's mood at that time, it is not difficult to understand.

What she wanted to do was to use a towel with ether to stun Li Yanan, and then take the money away, which was a robbery, so she was extremely emotional, ate a pimple soup, and choked to death.

On top of that, I suspect that she did something to herself in advance.

Previously, the medical examiner believed that Zheng Xiaowu had a pimple soup in his throat because the corpse giant was pushed out by the gas in his abdomen after being contemplated, but my opinion is that she said that she was choked to death when she was absent-minded, emotional, and had poor physical self-control.

At that time, when Dr. Sun Jie mentioned this matter, I also specially checked and found that in history, there was an important person named Song Ziwen, who accidentally choked a piece of food into his trachea due to excessive excitement during eating, resulting in poor breathing, and finally died suddenly due to heart failure. And it happened in Xinjinshan in Jianguo at that time, and the medical conditions were still good.

No one knew about Zheng Xiaowu's death, and Guan Shanyue sneaked over at night.

He didn't know that there were two corpses in this villa, and if he knew, he would have been scared to death, so he couldn't go to the kitchen and basement to find money, so he went directly to Li Yanan's house.

He went and found that there was no one, so his reaction later should have been that he knew about the disappearance.

Judging from Guan Shanyue's reaction now, Guan Shanyue should have gotten the money, but he definitely didn't take it all, he knew that if he took away part of the money, Li Yanan would not be able to call the police.

So Guan Shanyue has been secretive.

After a day or two, Li Yanan found that no police came to find him, and came back and threw Lin Mingfei to the ground, that is, during this period, the flies in the perennially warm villa laid eggs.

It was so warm in the villa that a day or two was enough time to start rotting.

After throwing it into the ground, Li Yanan didn't know what to do, so he turned off the heating in the ground first, and then ran away to find a way, and finally felt that he should throw the corpse.

In fact, Li Yanan should be very panicked now, I very much suspect that he is preparing to smuggle out of the country, this person is really not bold. ”

After Bai Song finished speaking, Wei Ju also listened carefully and said, "What you said has some truth, but there are a few problems. ”

"First, let's talk about Zheng Xiaowu first, according to our experience, it is true that the carbon monoxide produced by the incomplete combustion of the LPG tank is difficult to reach a lethal amount, but if she choks to death, then, will the hemoglobin continue to bind after the carbon monoxide dies?" Speaking of this, Wei Ju paused for a moment and moved his gaze to an old forensic doctor from the city bureau beside him.

"After death, red blood cells will rupture, hemoglobin can combine with carbon monoxide in the air, but the ability is very poor, and because of the lack of spontaneous breathing, carbon monoxide is not detectable in the blood of the body except for the surface layer of the mouth and other places. The old forensic doctor understood what Wei Ju wanted to ask, and replied directly.

Wei Ju nodded and looked at Bai Song.

"Wei Ju, I have a reasoning about this, I don't know if it's right, can I say it together in the end?" Bai Song was still thinking about this matter.

"Okay", Wei Ju then asked: "Second, when Zheng Xiaowu's body was found, the people from the Xingang Branch, after arriving in the house for the first time, felt dizzy after breathing for a while, indicating that the concentration of carbon monoxide is still relatively high, which is also the main reason why the forensic doctor believes that the cause of death is carbon monoxide.

Third, about Li Yanan, from common sense, he saw that Wang was annoyed to death, and then saw Lin Mingfei holding a hammer to close the valve, he could completely escape, as a man, he would not be unable to escape. Moreover, killing people is not a trivial matter, and in terms of motives, it is difficult to explain.

Fourth, in this same case, both people died unexpectedly, and it was such a coincidence, it was too strange.

Fifth, if Guan Shanyue took the money, in the current situation, Liu Shushu has no need to hide this matter.

Sixth, it is the source of ether, Zheng Xiaowu's resume is also here, and everyone knows it. ”

Director Wei was born as an old criminal policeman, and he caught all the key to the problem at once, he looked around for a week, and no one added, as his eyes gradually moved to Bai Song, other eyes also focused here.

"I do some reasoning, I still need to verify, if there is a problem, I hope the leader will bear with me. Bai Song felt that his thoughts were not necessarily right, but since it was already this time, he took a deep breath and said, "Let's talk about the first and second and sixth first.

Personally, I don't think LPG is completely burned and doesn't produce as much carbon monoxide.

I think all of you here think so too, after all, the gas stove in our home has never said that so much carbon monoxide can be produced because of insufficient combustion.

However, carbon monoxide was found in the deceased's body, and at the same time, there were conditions at the scene that could produce carbon monoxide, which made us have to consider carbon monoxide poisoning.

And I think that carbon monoxide was not produced by the gas stove on site at all, and it may be that Zheng Xiaowu deliberately found a place to inhale carbon monoxide when he obtained ether, which led to the presence of this substance in his body.

As for the access to ether, it is likely that something else is involved, which is not yet known.

Why Zheng Xiaowu can inhale carbon monoxide, this is very simple, carbon monoxide poisoning is a very individual poisoning, a small amount of mild poisoning inhaled, very little harm to the human body, inhalation of fresh air, out of the poisoning environment, the symptoms will disappear quickly, generally no sequelae, but, there is still carboxia hemoglobin in the body.

She did this to increase her insurance, if Li Yanan called the police and said that she had been stolen or robbed, and the police checked, she could avoid being investigated very safely on the grounds of carbon monoxide poisoning and delirium.

At the same time, the gas stove over there was also deliberately made by her.

If she said why she inhaled carbon monoxide first, it means that the place where she obtained ether was not very easy to go, so she was ready to go once. And she eventually choked to death, in addition to agitation, it was also related to a trance caused by mild carbon monoxide poisoning.

Low levels of carbon monoxide, if she doesn't have an accident, waiting for her to go out with a towel for a while, and then breathe fresh air, almost no effect, and the environment inside the house is still easy to make her trance. ”
