The professional quality of the male protagonist

If this is the case, then there are not many people who have the conditions to commit crimes.

First of all, the other party must be very familiar with the victim's work and rest situation, and at least be able to avoid people's eyes and ears.

When the crime happened, there were quite a few people in the village, but they didn't hear any voices calling for help. During the time when Gu Mute was poisoned, he didn't see the rest of the people going in. To put it another way, the other party might have It has been buried in the victim's home.

Thinking of this possibility, Zhang Xuan was a little surprised and turned to the surrounding people. Sure enough, they all thought of the same thing.

"If the other party is really buried in the victim's house and ready to attack, then Gu Duba is probably the only one who saw the victim before the murderer committed the crime." Ye Kai said.

"It's not impossible. According to the time, the victim was still alive when Gu Dumb poisoned him, so he may have seen the murderer." Zhang Xuan said.

Xie Wenyuan, who had been silent by the side, suddenly made a sound at this time, and he said: "Do you think there is such a possibility? The murderer already had a plan to kill the victim, and he sneaked into the victim's house in advance to ambush, and then prepared to strike , As a result, Gu Mute sneaked into the victim's house at this time. The murderer was at the victim's house at the time, so he clearly saw Gu Mute poisoning. He didn't make a sound but followed his tricks. He also poisoned the victim's house. Increase the chances of the victim being poisoned, and then wait until the victim is poisoned before preventing him from calling for help, all this is logical."

"But in this way, the clues we investigated before will be completely useless." Ye Kai had a headache.

Not only Ye Kai, but the rest of them started to have a headache.

If it was really as what Xie Wenyuan said, then the matter of Gu Dumb had nothing to do with this matter at all, and the previous investigation about Gu Dumb would be meaningless.

Although the poison is a clue, it is very difficult to find a needle in a haystack in terms of time. It may be a day or a year. No one can tell, but this kind of thing has always been a long time, and there is no way. investigate further.

"If this is the case, then the murderer should be someone close to the victim, at least he has been to his house." Zhang Xuan didn't feel disgusted by this, and after thinking about it, he said: "Besides, if the murderer committed the crime according to Xie Wenyuan's deduction, then There is a very contradictory thing here-the murderer did not need to poison at all."

The reason why they found that there was a problem with this case was because they found a strange contradiction in the water tank, so they kept investigating.

If the murderer didn't do anything unnecessary and deliberately poisoned the water tank, I'm afraid even the police like them wouldn't be able to detect something wrong in the first place.

Several people thought about it and couldn't think of a more correct answer, but this was indeed a new clue, so several people began to discuss the previous question again.

Is Gu Dumb a stand-in, or does it really have something to do with this matter.

However, no matter whether Gu Duba is a substitute or not, he is the one who may have seen the murderer.

Therefore, the position of Gu Dumb in this case suddenly became more important. Zhang Xuan, who had gone in to interrogate Gu Dumb countless times, had no choice but to collect information again and went to the interrogation room where Gu Dumb was.

The rest of the people didn't stay idle, and returned to the village where they were before, but this time their investigation was completely different.

The teams dispersed to investigate the clues in hand, the manpower kept changing, and the only constant was Li Yancheng's side.

After Li Yancheng left the police station that afternoon, he immediately went to the place where the couple worked. According to the clues provided by the couple, Li Yancheng easily found the company where the two worked.

It was a foreign trade company, and the husband and wife were not highly educated, so they only did some miscellaneous jobs in the company.

The man works as a cleaning staff in the security room, and the man works as a warehouse keeper. Both of them are in the same company.

They live in a rented basement not far from the company. Because of the remote location, the rent is too high, but the air is not very good.

After Li Yancheng arrived in the local area, he immediately visited the company. The two of them were still at work on the day of the victim's accident, so they found a place to live.

On the day when the incident happened, the woman was on shift for a day off, but he went to work normally for the first and last two days, because the round-trip time from here to the scene of the crime would take more than ten hours at the fastest, so he had time gaps. Exclusion criteria not met.

It's just a one-day vacation, even if he wants to, there is no way to go back and forth.

And that man has been working, so there is no way to leave.

In this way, the victim's case really has nothing to do with the two people, but it cannot be ruled out that they may know something.

Li Yancheng originally planned to go back after confirming the alibi of the two people, but after seeing the place where the man worked, Li Yanchengjue decided to stay for a night.

Because that man is a warehouse manager, the company's warehouse is in the underground parking lot, and no one goes to that place all year round, so even if he said that he was at work, no one could prove it.

But the woman had no suspicions.

The matter could not be completely confirmed, Li Yancheng would not give up lightly. After resting all night, he went to the administrator the next morning, hoping to check whether the man had gone to work or not.

This company is a foreign trade company, with a service desk at the front desk and some offices upstairs.

Li Yancheng was invited to a living room, and the person who entertained him was the manager at the front desk.

After hearing Li Yancheng's intentions, the other party politely invited Li Yancheng to sit down and drink tea, and then he himself went to verify the matter with the staff at the time.

The other party came back about half an hour later. When the other party came back, he was still carrying a tablet computer and the evidence that Li Yancheng wanted.

It was a video clipped from the surveillance video. On the day Li Yancheng specified, at the time of work in the morning, the man walked under the surveillance video outside the warehouse at work hours, and opened the door with his back to the surveillance video. , and then into the warehouse.

There is also a video of the other party leaving after get off work. These two videos can fully prove that the victim was in the company even during working hours.

Li Yancheng checked the video carefully, and asked the other party for the video before returning to his rented place.

At about noon, Ye Kai called and told Li Yancheng that they had found the wholesale market through the clues from the pesticide side.

Although Li Yancheng felt that this clue might not find much, he didn't want to dampen Ye Kai's enthusiasm.On the other side, Aman called Li Yancheng immediately after Aman finished the autopsy report.

This is what Li Yancheng requested.

Li Yancheng was not very surprised that the victim was restrained after being poisoned, unable to escape at home, and then delayed for time.

He always felt that this matter was very strange. The contradiction was not just in the fact that the poison had to be poisoned in two places, but that there should be some relationship between the victim and the murderer.

The situation in the victim's home was very messy when they went there. It was obvious that the victim was not a person who liked to do housework.

In such an environment, coupled with the victim's own personality, most people are basically unwilling to be guests. If they are not very familiar with the victim, people who have visited his house many times should not be able to make the victim feel comfortable. Get up, and don't let him make a sound to be found.

And when the police really wanted to investigate, they didn't find any traces of restraints in the house.

The other party obviously had a premeditated plan, but this premeditated plan also exposed him a lot.

He is aware of the contradiction between Gu Duba and the victim, the environment and family situation of the victim's home, and he is sure that no one will go to the victim's home when he did it. He also took the 'murder weapon' after he left, which shows that the other party is very serious to this family. familiar.

Among those who can meet these conditions, Li Yancheng suspects this couple among the people he knows so far.

Therefore, Li Yancheng chose to continue the investigation even after seeing evidence that these two people were not present.

Although there is indeed a video of the man's working hours, it is not [-]% sure that this is the person involved. If the woman went to 'work' for the man in the first place, and then let the man have a chance to go home, it is not impossible.

The woman is on vacation two days before and after, and only works for one day in between, so if she replaces her husband for three days, it is entirely possible to do it.

It's just that now that the evidence is all there, how can he find out the tricks from the evidence?

Li Yan was originally planning to ask Liao Qun for help, but after thinking about the previous incident, he still hesitated.

After the previous incident, Li Yancheng was not troubled, but Liao Qun was not ignored like him.

And even if the chief didn't bother him intentionally, the rest of the people wouldn't let him go so easily.

Therefore, the last time Liao Qun communicated with Li Yancheng, it was not because he was afraid of those who would trouble him.On the contrary, it seemed that Liao Qun made a series of counterattacks because the opponent had completely pissed him off.

Although I don't know what he did, but judging from the tense atmosphere in the police station, it shouldn't be a good thing.

Now that the smoke of the war has just dissipated, if you contact him at this time, it is very likely that the rest of the people will find out.

Li Yancheng didn't intend to make a fuss, and according to Liao Qun's character, he must avenge any grudge, and he should be very busy.
