Chapter 632 Carbon Monoxide

Team Zhou didn't stop for a moment, and took Tang Weili back to the police station as soon as he went out.

If there are no suspects with a direct connection, the police may consider looking into it.But Tang Weili was the deceased's ex-boyfriend. This connection was too special, and the suspicion directly rose to 800 million. If he was not sentenced directly, it would be considered a society ruled by law.

On the other hand, although this case is not a murder in a secret room, it is very certain that the murderer deliberately planned the murder.

This method of killing is fundamentally different from the victim being stabbed, or being sapped in the back of the head.

Being beaten by a knife or sap can be interpreted as a murder of passion. Of course, the court may not necessarily approve it, but during the police investigation, as long as you do things under the terms of the law, your thinking does not need to be legal thinking.

As a natural person, it is conceivable that even if you carry a knife to meet someone, it does not mean that you must kill the other person.But if you put a bottle of carbon monoxide in your pocket, the nature of the murder must increase exponentially.

It doesn't take a lot of work, and you can't even get it.

Now that the murderer has planned to this extent, any surveillance by the police will give the murderer a chance to eliminate evidence.

Team Zhou even made it possible for Tang Weili not to confess. After arresting the person, he searched Tang Weili's house immediately with the survey. The trash cans were all cleaned up.

All containers that seemed to be able to hold carbon monoxide were found.

Unfortunately, nothing was gained.

But this time, everyone, including Team Zhou and others, was not in a hurry.

Facing a city with millions of people, it is really difficult to find the murderer.It is a bit too much to say that finding a needle in a haystack is also part of the difficulty of catching wild large yellow croakers.

But if there were already key suspects, the situation would be different.

Especially the key suspects in key murder cases are treated basically the same as the targets of the Criminal Investigation Division of the US Internal Revenue Service.

The detectives first checked Tang Weili's cell phone, and checked his bank account and money flow at the same time. The third team traced his whereabouts, and everything was clearly arranged.

The people around Tang Weili were also questioned and investigated one by one...

Not to mention the sky net, but the net used by the police, many ordinary people may have never seen it, such as bayonet, identification, fences, etc. Many technologies did not exist a few years ago, but now they appear with a whimper up.Policemen have to study and train themselves, how can outsiders know so much.

As for not using electronic devices... It turns out that Tang Weili really did. He rode a bicycle, went out from his own community, and went straight to the community where the victim lived.

It's still the theory of the wild large yellow croaker. It's very difficult to find it in the sea. Now I'm looking for Tang Weili's whereabouts. There is a face recognition access control at the gate of his community.

There are really not many people who go out at 5 o'clock in the morning.

Along the way, the surveillance cameras are incomplete, but when passing the checkpoint, there will always be a full face.

As for why he went out at five o'clock in the morning, Tang Weili couldn't explain it clearly, but there was still a certain distance from giving up resistance.

Looking at Tang Weili's round face and small round eyes in front of the one-sided glass in Changyang City, Jiang Yuan and others felt a sense of resilience.

"I didn't expect this little fat guy to have a good mental quality." Mu Zhiyang said with emotion: "His own words are full of holes, and he insisted that he was innocent, so stubborn."

"He's in business, and he's exposed too often, so there's nothing he can do about it." Wang Chuanxing was holding a pad in his hand, and it was full of documents.

Mu Zhiyang said: "It's a good day, but I don't know what is the motive of killing such a big hot pot restaurant? If I had such a big hot pot restaurant, I would get up at five o'clock every morning to cook hot pot."

"The hotpot restaurant's business is not good, and it's losing money." Wang Chuanxing was reading the latest news, turning the page, and said, "The turnover of his restaurant is not high, and there are more than 30 employees, and the monthly labor cost is about ten. Dowan, and the rent is about to expire, so his financial situation should be pretty bad. Could this be the motive?"

There are three kinds of criminal motives, lust for money, lust for sex and desire for aggression.The state of the economy is rightfully one of the main points of concern.

There were seven or eight people in the small room, all of them were a little restless, and they started talking about it:

"Unless Yue Ling, the victim, sells the house, he won't be able to fill in the bottomless pit of his ex-boyfriend. Besides, what good is Tang Weili killing her?"

"Whether this hot pot restaurant was opened before or after the two broke up, will there be any economic disputes?"

"The secret recipe of the hot pot restaurant?"

"This hot pot restaurant is about to close down, and the secret recipe is worth a lot of money."

"Are the two dating in secret? The man's hot pot restaurant's business situation has deteriorated, and the previous promise can't be fulfilled?"

Everyone is guessing, and what they say seems to make sense, but there is not enough evidence to support it.

Those with lesser personalities are already pulling their hair out.

If there is a fair point of competition between the police and the robbers, the psychological competition should be ranked first.

When the suspect is in self-doubt and suffering, the police are actually in self-doubt and suffering.

Looking at the discussion from the perspective of the person in charge can also explain a classic truth: reasoning has an egg.

"How is the investigation of the source of carbon monoxide?" Jiang Yuan interrupted everyone's discussion.

"No news yet." Wang Chuanxing checked and replied.

In fact, he has been thinking all the time. As far as his personal thinking mode is concerned, finding evidence is the first thing he needs to consider.

The most important evidence in this case is carbon monoxide.

Carbon monoxide can be produced by itself, and it is possible to produce carbon monoxide from vehicle exhaust or incomplete combustion. Therefore, in terms of scarcity, carbon monoxide is not worth mentioning.Even in the air itself.

But the victim's manner of death was acute.As we all know, there are usually three types of death caused by carbon monoxide, which are lightning, acute, and chronic, and the latter often takes half an hour to die.A typical example is suicide by burning charcoal, and the death is very slow, which belongs to the slow production of carbon monoxide, which kills people slowly.

In order to achieve acute carbon monoxide death, the concentration of carbon monoxide must be high enough, and the concentration of carbon monoxide produced by oneself is difficult to meet this requirement.

This should be in the murderer's consideration. If it wasn't for the high concentration of carbon monoxide, the victim would have opened the door and come out when he realized something was wrong.

Assuming that Tang Weili is the murderer, how did he obtain the high concentration of carbon monoxide?

It is nothing more than two routes offline and online.

If you are offline, you can visit the relevant stores; if you are online, you can check the sales records.

It is said that a round of investigation has already been conducted online, while Team Zhou is conducting an investigation offline.

Jiang Yuan thought of how he used to go to his family's shop to collect rent, and those shopkeepers who were not doing well, moving around and paying in change, turned his head and said to Wang Chuanxing: "Tang Weili is in business, and he may have more than one account. Ask the employees of the hotpot restaurant, especially those in charge of finance, to find out Tang Weili's other accounts to see if there is any record of purchasing carbon monoxide."

"The accounts under Tang Weili's name have been checked... You mean, the accounts are not necessarily under his own name? We have also checked a few accounts of other people in their store." Wang Chuanxing said while looking for records.

Jiang Yuan said: "Expand further, try your luck."

"Yes." Wang Chuanxing agreed, and began to call to arrange personnel.Jiang Yuan said that it was just a matter of luck, so it should be expanded a bit. Now that the case has basically been solved, it is indeed possible to be more wanton.

evening.

A group of people from Jiang Yuan went to eat mutton noodles in Changyang City.

The mutton soup is the most fresh, whether it is mixed with noodles or flour, as long as it does not steal the taste, it is extremely delicious. In the end, as long as the store’s Mozi is good enough, the secret recipe should not be too weird, it depends on the performance of the mutton how's it going.

Sitting in the mutton powder shop, Yu Wenshu finally found a reason to go home late and said with a smile: "In today's terms, this shop is my favorite shop. Sometimes when I go home at night, I will go home late." Come and eat a bowl of noodles first, and then go back."

Huang Qiangmin clicked his tongue: "It's so delicious, so I must try it."

"Well, you can serve it with some cakes. If you have a small appetite, you can just eat meat and drink soup. For example, people who have a cold come to this shop, drink a bowl of soup with a snort, blow their noses and blow a lot, and they can catch a cold. Half as good." Yu Wenshu highly praised it.

In fact, as long as you don't go home, Yu Wenshu will eat well.

Huang Qiangmin didn't expose him, he ate some cakes cooperatively, and praised him a few more.

When it was time to go out, Yu Wenshu was still reluctant to part...

At this moment, a call came to Yu Wenshu's cell phone.

Yu Wenshu, who was about to go home, looked down at the number and immediately picked it up. Without saying a word, a sincere smile appeared on his face.

After hanging up the phone, Yu Wenshu turned around and said, "The source of carbon monoxide has been found. An old employee of a hot pot restaurant has a record of online shopping for carbon monoxide under the account. In Tang Weili's hands!"

When he said this, Jiang Yuan and the others also became happy.

Yu Wenshu waved his hand: "I have to go back and have a look. You guys should rest first, especially Jiang Yuan, you must get enough sleep. Alright, I'll go back to the police station first to see the specific situation. You can come to hear the result tomorrow." ..."

Looking at the back of Yu Wenshu returning excitedly, Huang Qiangmin thought thoughtfully: "He deserves to be the detachment leader."

Liu Wenkai said quietly: "Marriage makes people grow..."
