The professional quality of the male protagonist

After explaining these things, Li Yancheng wanted to see the mother and son for a while, but he happened to meet Zhang Xuan when he went, and Zhang Xuan told Li Yancheng that he had better not go at this time.

After the poor child was caught, his mother was also detained in the police station. Originally, they were just planning to stay for a while and let the other party learn their lesson before releasing her. After all, this matter was not a big deal at all. , Besides, mothers can do everything for their children, and they can understand.Moreover, the injured policeman only suffered some flesh wounds, and after going to bandage it, he has been fine.

But what surprised them was that the woman had been unwilling to cooperate with their work since she was initially arrested, and except for the first few days when she showed a great attacking intention, her mental state had been a little weird for the next few days.

At first, they just thought that the other party was too angry, which caused some mental weakness, but later when they found that the woman was talking to herself in an empty room, they finally saw some signs.

Later, they let the two meet through the glass, but the woman's condition did not improve, but worsened, she kept talking to herself, and seemed to be able to see some hallucinations that they couldn't see.

Afterwards, the police station invited some psychiatrists to investigate and concluded that the other party was hit hard by this incident and was likely to have a mental breakdown.

In just one year, her husband died in an accidental car accident, and her son committed such a serious crime...

That seemingly strong woman could no longer bear the pressure.

After listening to Zhang Xuan's words, Li Yancheng thought about it, but finally did not go to see the mother and son, because for the two of them, maybe Li Yancheng was the culprit of the change.

The boy's methods are not very good, and sooner or later his mother will find out that he did all this, and by then, his mother may have recovered from her husband's pain, although it is likely to be in pain Among them, it will not collapse so easily...

After staying in the police station for a while, Li Yancheng received a notification letter from the chief, asking them to bring everyone back to the police station immediately.

It has been a month or two since the previous incident and the turmoil has basically passed. They have been in other places and have no work to go back to wait for a while, and many bureau chiefs mean to let them go back to work.

In the past two months, they had enjoyed themselves quite happily, so they felt a little depressed when they suddenly thought of going back.

But thinking of going back to work, everyone packed their luggage immediately and booked their tickets for the next day.

There are also some finishing touches, which have already been done a day earlier. After gathering at the hotel that night, everyone went to rest early. The next morning, they had to leave early for the plane at 9 o'clock in the morning.

At about 10 o'clock, the door of Li Yancheng's room was pried open. The person who knocked on the door was the police chief who followed them to investigate the case. After seeing Li Yancheng, the other party scratched his head in embarrassment, and handed it to Li Yancheng Cheng made a document, and said with a smile: "You are going back tomorrow, can you do me a favor?"

Li Yancheng stood at the door and looked at the document he handed over. Before he could speak, Zhang Xuan asked from behind, "What's going on?"

"I'll go out and have a look." Yang Yang raised the information in his hand to Zhang Xuan, and then he walked out the door.

The latter frowned in disapproval, but did not stop him.

Li Yancheng followed him to the public living room downstairs of the hotel. The two sat down one after the other. Li Yancheng looked through the information again, and then looked at the policeman suspiciously.

Seeing that Li Yancheng wanted to help, the policeman quickly explained: "The thing is like this. Some time ago, our bureau detained a murderer, but there was no way to settle the case, so I would like to ask you to help us find out whether we made a mistake or not. He did it on purpose."

The specific situation was mentioned in the information Li Yancheng read just now, and it was not a complicated case - a case of poisoning and homicide.

The person who poisoned him was a man, from the countryside, 30 years old, stuttering, nicknamed Gu Dumb.He has a simple and honest personality, doesn't like to argue with others, and is quite popular in the village.

The deceased was a man of the same age in the same village. The man was also a local. He was in his 30s, but his personality was completely opposite to that of Gu Dumb.

The two of them had always been at odds, and there had been conflicts about the victim giving Gu Dumb a cuckold before, so after Gu Duba was caught at the police station, everyone was not surprised.

But after Gu Dumb was taken to the police station, his parents went to the police station one after another, saying that they killed the man and that they were the ones who poisoned him, not Gu Duba, but Gu Duba firmly claimed that he poisoned the murderer himself.

Such a situation needs to be investigated, but the results of the police investigation are the most unfavorable to Gu Dumb, because he bought the drug on the street the day before, and Gu Dumb is the most likely person who poisoned him!

Although his parents were doing farm work not far from the same village, they would be in a hurry because of the limited time to go back and forth, and Gu Duba was resting at home because of a sprained foot that day, so he had the most time in terms of time.

In addition, they found Gu Duba's fingerprints in the victim's home, so all the evidence points to Gu Duba!

After bringing the person back, they immediately asked people to identify what they had done, but at this moment, they found that something was wrong.

Gu Dumb described all his actions and plans to the police that day, and took them to the victim's home to identify the specific methods and means of committing the crime.But Gu Dumb, the first half of what he said is basically completely true, but there are subtle deviations in the second half.

The medicine was indeed bought by Gu Duba, and the medicine that the victim was poisoned was exactly the same as the medicine bought by Gu Duba.But when Gu Duba took the police to the victim's house to testify, he testified that the poison he injected was in the victim's usual water cup—but the victim's poison should have come from the water tank.

The situation at that time was that the water in the water cup was full and there was no obvious trace of being touched by people, but there was a large amount of urine in the water tank.

Because the ingredients of the drug were exactly the same, and only the fingerprints of Gu Yaba appeared in the victim's home, the police suspected that Gu Yaba had also poisoned the water, but because he was too nervous at the time, he missed it.

But after that, no matter how Gu Duba recalled, he always remembered that he did not poison the water.

During this period of time, his parents didn't stop, they kept going to the police station to say that he killed himself and had nothing to do with Gu Dumb's child, and Gu Duba's personality was always honest and honest, not like the kind of person who would poison.

This case was already about to be finalized but this kind of thing happened, so the policeman came to Li Yancheng to see if Li Yancheng could deduce that the old mute was deceiving on purpose.Or is there really another secret.

"The ingredients of □□ are exactly the same?" Li Yancheng asked.

"Yes, exactly the same," said the policeman.

"Then where is the rest??" Li Yancheng asked again, "If the other party poisons the water cup, there should be a lot of drugs left. If he pours all the rest into the water In the tank, the remaining □□ should have the wrong amount.”

"Serving size?"

"That depends on the volume of the water tank. If the volume of the water tank is large enough, the most common capacity may not be able to reach a fatal level." Li Yancheng said.

Li Yancheng has seen the kind of water tank commonly used in rural areas. It is big enough for a person to lie flat in it. If it is just an ordinary container, it will make people dizzy and vomit at most.

"I'll ask someone to investigate this matter." The policeman put away the documents and nodded, thanked Li Yancheng and hurried away.

Li Yancheng went back upstairs, rested after washing up, and prepared to board the plane the next morning.

But their trip this time was not destined to be so smooth. When everyone arrived at the airport waiting room the next morning, Li Yancheng's phone rang again. The caller was the policeman who was looking for him last night. Dumb bought it.

——□□Hardly used.

□□Although it was opened, only a little bit of it disappeared, and the amount was probably only enough for him to poison the water cup.

When the policeman said that, he felt very strange at the same time, why would he admit it if it wasn't for the poison of Gu Duba?Moreover, his parents kept coming to the police station to confess their crimes, as if rushing to admit it.

If it is to cover who?Well, it's still clear, but if it wasn't the poison from the tiger's teeth, then it was his parents?

It's just that his parents' police station has already investigated it before, and there is no possibility of killing him. Although there is still plenty of time, there is also the possibility of killing him, but the other party did not buy drugs.Moreover, the only drug in his family was the bottle bought by Gu Duba, and the dose was not enough for them to kill people.

What the policeman meant was that he hoped that Li Yancheng could help him take a look, after all, this matter was also somewhat abnormal.

Li Yancheng did not make the decision alone, but told the rest of the police about this matter, so that they could see if they would take up the case, or return to the police station immediately.

Without further ado, Hu Xingfan immediately asked Li Yancheng to handle the case. He didn't want to go back so soon. Ye Zhong also meant the same thing. He and Hu Xingfan had been staying in the bureau to treat Hu Xingfan, and because of this, many people came to bother him. he.Although Li Yancheng and the others were relieved, the other party was very distressed.

Ye Zhong also booed, not intending to go back so soon at all.
