The professional quality of the male protagonist

The place where the old man had an accident was on the way home from the vegetable market. During this period, the time the murderer could poison was only when the old man went to the vegetable market for nearly an hour.

After the time point was roughly determined, the old man's eldest daughter was naturally included in the suspects, because no one else had contact with the old man except her during this day.

However, the possibility of her daughter committing a murder is not high. Although he has the time, he can't do it.

It is impossible for the old man to drink all the alcohol willingly when he knows it is ethanol, and then go shopping with his daughter talking and laughing.

So the old man must have been unaware of it before, and the crime should have happened after that.

After that, Zhang Xuan began to suspect the rest of the people in the vegetable market. Zhang Xuan adjusted the surveillance video from several shopping malls around the vegetable market. The silhouette of the market.

During nearly an hour, the two never separated.

And because there are so many people in the vegetable market and there are so many eyes and ears, it is impossible for someone to take this opportunity to force the old man to drink his most taboo alcohol.

But once this condition is met, this case will undoubtedly become an unsolved case.

Zhang Xuan couldn't find the person who poisoned him, so he had to start investigating the source of the alcohol. The alcohol in the old man's stomach was of high purity. Judging from the conclusion alone, the old man drank a lot of alcohol.

Moreover, the main location of alcohol is mostly in his blood, and part of it is in his stomach, so the possibility of being injected with alcohol cannot be ruled out.

Zhang Xuan was very busy, but An Xiang also got involved.

Because the old man had bought a huge amount of insurance before his death, and now the old man died in an accident, so the insurance will take effect immediately.

There was nothing wrong with all of this, but the insurance company refused to admit it, and they took the initiative to hire a lawyer to counterclaim.

After investigation, the insurance company felt that this might be an insurance fraud incident, so it refused to sign the insurance compensation document, and coincidentally, An Xiang happened to be one of the lawyers hired by the insurance company.

An Xiang was invited to his main purpose is to let the insurance company not pay this sum of money, the only condition for this is that the old man did not die because of an accident, but because of murder, so An Xiang also started to inquire The beginning and end of this matter.

Zhang Xuan, who had no clue at all, immediately pointed the arrow at the old man's son, Ma Wenguang, after hearing about it.

After some investigation, Zhang Xuan was surprised to find that although Ma Wenguang had a good relationship with the old man in name, he had already tried to get a sum of money from the insurance company three months ago. The company couldn't accept it, so he didn't succeed.

In the next 3 months, Ma Wenguang suddenly had close contacts with the old man of their family. He often went home to visit the old man, and often brought some supplements to the old man.

Before that, Ma Wenguang basically had little contact with the old man. After Zhang Xuan conducted an in-depth investigation, he found that although Ma Wenguang had this company on the surface, in fact his company was already in the red. The money in the company was due to his improper investment. Already lost out.

Therefore, he has enough reasons and motives to hurt his old man, but the method is not yet clear.

When investigating his elder brother, Zhang Xuan was surprised to find that his elder brother was not the only one who had problems in their family, but also his daughter.

The old man's daughter, like his brother, had been indifferent to the old man for several years before, and it was only in these three months that she suddenly started to approach the old man.

Unlike her eldest son, she also moved back to live at home, cooking something for the old man to replenish his body on weekdays.

Externally, her daughter said that the reason was because she couldn't bear to see the old man living at home all year round.After all, the old man is already old, so he must be taken care of.

Under Zhang Xuan's investigation, it was found that although his eldest daughter's financial situation is actually good, but because of her husband's relationship with her, the two are in a state of divorce.

Therefore, it is not impossible for her daughter to be jealous of the old man's insurance.

After the suspect was identified as the old man's own family, Zhang Xuan immediately searched all the places in the house, but after searching the whole house, he didn't find anything related to the spread of ethanol.

As the old man's eldest daughter said, because the old man is allergic to alcohol, all the food in their house has been adjusted, not to mention the food, even the disinfectant prepared in the medicine box is saline.

Even so, the most likely suspects are the brother and sister.

Because the possibility of other outsiders committing crimes in terms of time and place is very low, only these two people have all this.

Zhang Xuan interrogated the two separately, but the answers he got were ambiguous. Naturally, the two absolutely did not plead guilty. At the same time, their words were full of hints to attract the police to the other side.

The words of the two were obviously deceitful. Zhang Xuan told one of them that the other party had pleaded guilty. The same statement was tried once by each of them. As a result, Zhang Xuan broke the case after a short interrogation.

But although the case was said to be solved, Zhang Xuan had no evidence to prove that the two were the murderers.

According to the account of the two, the two of them already knew that their father had a huge amount of insurance, so after encountering difficulties, they went home and asked the old man for help, hoping that the old man could help.

But the old man has always been upright, and the relationship between the two children is not harmonious, and he does not agree with the reinvestment of the eldest son, and even more disapproval of the divorce of the daughter, so he rejected the request of the two.

Unexpectedly, there was resentment in the hearts of the two of them, and all this was designed.

The two decided to poison the old man. If the old man died in an accident, then the insurance would get a huge amount of money back. The two had even secretly negotiated how much the insurance compensation would be divided into.

The two who were jealous of money didn't take into account the old man's kindness to them at all. Naturally, after choosing a specific time, they gradually began to get close to the old man, and at the same time began to design another seemingly unexpected case.

The old man has always been in good health. If he died in an accident, he must not die in an accident that is too strange, so the two put their minds on the old man's allergies to alcohol.

If it was accidental drinking too much poisoning, naturally it has nothing to do with them, and the death of the old man can be judged as an accident, and the insurance will take effect.

After making up their minds, the two started to fight, but they didn't expect to end up like this.

However, although the case has been generally understood, Zhang Xuan has been unable to arrest him, because he has not found evidence that the two of them were clearly poisoned. Although the old man has died of poisoning, the method of poisoning is unknown.

Zhang Xuan tried to ask the two of them, but they had always been silent about the killing of the old man, and they were unwilling to cooperate.

And according to the law, if two people deny the fact that he killed, and the police can't produce clear evidence that the two are the murderer, they will be released after being detained for a period of time at most.

Oman has been busy with this matter for a long time. As a forensic doctor, he naturally examined the corpse carefully.But there was no evidence of abuse or coercion on the body. The alcohol was definitely drunk by the old man himself, not forced by the two of them.

There is another thing that can prove this point, that is, before the old man was suddenly poisoned, he was shopping outside with her daughter. If his daughter or his son forced the old man to drink such a large amount of alcohol, it should be impossible for him to be on the street with the other party. grocery shopping.

Zhang Xuan once visited the vegetable stall owners who had seen the two in the vegetable market, but they were not very impressed with the two. The only two who could clearly describe the characteristics of the two also agreed that the old man At that time, his expression was normal. It didn't seem like he had drunk too much alcohol, nor did he seem to have had a conflict with his daughter.

The method of poisoning was unknown, and Zhang Xuan tried to think of other ways to investigate, but he didn't come up with a clear solution.

Regarding this kind of matter, Zhang Xuan didn't think of Li Yancheng. After all, even Li Yancheng might not be able to solve this kind of matter.

Busy with the case and the work of the police station, Zhang Xuan, An Xiang, and A Man were almost dizzy.

When the three people heard the news about Li Yancheng again, they were a little dumbfounded, because the call was from the hospital, and Li Yancheng had entered the hospital.

It was after 3 o'clock in the middle of the night when the hospital called. At that time, Zhang Xuan and An Xiang were still carefully examining the corpse and related evidence in the bureau. Because An Xiang was in charge of the insurance, although he was yawning, he still insisted on staying in the hospital. The police station is waiting for the people of the police station to make a decision.

When the call came, An Xiang suddenly jumped up from the stool. Regardless of other people's strange eyes, he ran directly to Zhang Xuan and asked him for the car keys.

"What's wrong?" Zhang Xuan asked.

It is impossible to borrow a police car. If An Xiang wants to go somewhere, Zhang Xuan will definitely take him there personally or find someone to take him there, but An Xiang's current attitude does not seem to be a trivial matter.

"Li Yancheng has entered the hospital, and the doctor called." An Xiang said.

"What!" Zhang Xuan was also stunned. Li Yancheng has always been the most trouble-free one among them, and he never took the initiative to cause trouble. Why did he suddenly enter the hospital?And still at this time.

"Go and have a look, I just need to get some air." Oman put down the information in his hand.

It was after 3 o'clock in the middle of the night, the streets were empty, and the bright street lights on both sides of the road were dim and weak, and there was no sound.

Zhang Xuan took An Xiang and Aman to the hospital in a police car and asked the doctor. After the three entered the hospital, they found Li Yancheng in the corridor of the hospital. Zhang Xuan and An Xiang hurried over to ask what happened. thing.

Li Yancheng was in a bit of a panic, there were obvious bloodstains on his body, and his right hand looked a little bloated because it was tightly wrapped in gauze and hung on his chest.

He was sitting on a stool with a coat on his body, and he didn't know what he was thinking at the moment.

Hearing the voice of Zhang Xuan and the others asking, he just came back and glanced at the three of them, then nodded, as a greeting to the three of them.

"Why are you here?" Zhang Xuan tried to take a deep breath to calm himself down. An Xiang had already gone to the side to find the case list to check the situation.

"I met a person, and he rushed over suddenly." Li Yancheng said indifferently.
