"As for why our first wave of police officers felt dizzy after entering, I think it had nothing to do with carbon monoxide, but was due to hydrogen sulfide gas.

Hydrogen sulfide gas is the product of protein decay and deterioration a certain period of time after a person's death. Mild poisoning by hydrogen sulfide gas can also cause police officers to feel dizzy. Moreover, mild poisoning from hydrogen sulfide gas can still be quickly relieved after leaving the environment. Although it smells bad, the result is similar. "Seeing that everyone was deep in thought, Bai Song continued, "Let me answer the third question raised by Director Wei.

Why did Li Yanan do this?

This can actually answer the fourth question as well.

We have been handling cases for so many years, and many things are just coincidences.

It's not a coincidence that we encounter it, but it is precisely because of the coincidence that we can come.

Ordinary people may never encounter a car accident in their lifetime, but traffic police encounter them every day. It goes without saying how coincidental many car accidents are, but traffic police can see them all.

The same goes for us. We don’t have to consider coincidences. As long as this is the case, any coincidence is normal.

This matter requires consideration of Li Yanan's mood at the time. He was in a very bad mood and was very disgusted with Lin Mingfei. However, I carefully looked at the situation of these three female anchors, as well as the rewards given by Li Yanan in the live broadcast room.

If Li Yanan had to choose one among these three female anchors, he would definitely choose Wang Fanfan.

Let’s not talk about Lin Mingfei for now. Although Zheng Xiaowu is also beautiful, she is too scheming. Li Yanan is not stupid either, and he has seen beautiful women before.

So, in this situation, since he has already come here and since things have been ruined, he will definitely have more kindness towards the simple and lovely Wang Fanfan.

Then he found Wang Fanfan dead in the basement.

After analyzing it for a long time, we still feel that the possibility of this being an accident is very small. Li Yanan would not believe it even more. Zheng Xiaowu returned to his residence first. Who else could it be except Lin Mingfei?

So, he immediately thought that Lin Mingfei was the murderer.

If Lin Mingfei is the murderer, what is the purpose of killing Wang Fanfan?

It can't be that he wants to monopolize Li Yanan, right?

It's all about money after all.

If Lin Mingfei killed Wang Fanfan for money, would she leave him alive afterwards?

There is a problem here, which is that this location is very special.

This is not the city of Shangjing that Li Yanan is familiar with. In his opinion, it is very likely to be a remote area where no one lives. If he calls the police, how long will it take for them to arrive?

Out of fear, he saw Lin Mingfei put down the hammer to wash her hands. In that state of fear, he thought about subduing Lin Mingfei first, but the back of the human brain is very fragile and a single blow from the hammer would kill the person.

Then, he found out that he had killed someone, so how could he dare to call the police?

There is a special term in law for this kind of thing, called imaginary defense.

Imaginary defense refers to an act in which the perpetrator, due to a mistake in subjective cognition, mistakenly believes that an unlawful infringement has occurred, and in order to protect himself, he implements a defensive behavior, which results in damage.

There have been cases in history where someone dressed up as a ghost as a prank to scare someone, and the person who was scared picked up a knife nearby and stabbed the prankster to death.

In this closed villa, in that environment, if Li Yanan did such a thing, although it is incredible, it is not inexplicable.

The fifth and last question is why Liu Shushu wanted to protect Guan Shanyue.

I think this matter has something to do with Du Zigan.

Liu Shushu is a person who likes all kinds of interesting knowledge and talent, so much so that she doesn't even like rich people like Li Yanan. So, if someone like her were to like someone, it would definitely be Du Zigan.

As a doctoral student in physics majoring in popular science, Du Zigan also has his personal charm.

In her previous statements, Liu Shushu mentioned that she had a good relationship with Du Zigan. I used to think that she was the murderer trying to escape punishment, but now it seems that she has never been to this villa, and she has no motive to kill. She is just a little girl, and I don’t believe that she has such a strong anti-reconnaissance awareness.

As for why she wanted to hide it, I think the key lies in Guan Shanyue.

In fact, Du Zigan seldom talks to Liu Shushu. If Liu Shushu wants to know about Du Zigan's affairs, he can only go through Guan Shanyue, who lives in the same room with Du Zigan.

Zheng Xiaowu wanted to steal money, so she thought of pretending to be poisoned. Guan Shanyue also wanted to steal money, so there was only one way, which was to pull Liu Shushu into the same camp with him.

Liu Shushu is smart, but he is not as knowledgeable as Guan Shanyue about the crooked ways of society. Guan Shanyue will definitely tell him that this matter is related to Du Zigan and ask her not to mention anything.

In fact, Liu Shushu may not know that three people have died. She may still be in the dark, thinking that Du Zigan has some plan.

Now, I think the first thing to do is to interrogate Liu Shushu, and call Du Zigan over to confront Liu Shushu and Guan Shanyue face to face, and this matter can be solved.

The second is that Li Yanan's parents are both abroad. He beat someone to death. Given his courage, he must have wanted to find a way to smuggle out directly from Tianhua City through the port. Now we have to investigate thoroughly. Especially, the ship from his parents’ country. ”

There was one thing Bai Song didn't say, which was about the source of ether and carbon monoxide. He attached great importance to this matter, but other speculations had not been confirmed yet, so there was no rush for that matter.

When Wang Liang saw Bai Song finished speaking, he took out a bottle of mineral water from somewhere, handed it to Bai Song, and then stood behind Bai Song.

Sun Jie and Wang Huadong were also behind Bai Song. The group of four looked particularly energetic. They were all young people, which was rare in this room.

Liu Shuyuan also wanted to stand over, but he didn't move at all. He just looked at Bai Song in a daze.

Some of these leaders were from criminal investigation backgrounds, and some were not, but all of them were shrewd people. What Bai Song said might not be the truth, but it was logically consistent, which was something that no one present could do.

If someone could point out an obvious loophole in Baisong's analysis now, Baisong's previous analysis would fall apart.

But, no.

Director Wei was also thinking about the "imaginary defense" mentioned by Bai Song and Liu Shushu's situation. He remained silent, looked at Bai Song three or four times, and finally nodded: "Ask the people in Shangjing to bring Du Zigan over again and let him confront Guan Shanyue first.

Now go back immediately, tell Liu Shushu the truth, and interrogate her again.

Also, notify the customs, coast guard and other departments to strictly prevent smuggling in the coming days, and send Li Yanan's photo to each department. In any case, he is a serious and major suspect, so hurry up and track him down online. ”

…

As soon as Director Wei spoke, everyone was in awe.

This means accepting Bai Song’s words completely!
