Li Rizhi summoned the guards of the city gate, and the guards naturally came quickly, and the guards of the four city gates came one after another, all of whom were soldiers on duty on the night of the crime.

The guards of the four city gates are exactly four teams, of course, they are just called teams, in fact, they are just one, after all, Qianfeng County is only a county seat, and there is no war, so each city gate, ten guards are enough, when the city gate is closed, they still have the task of patrolling the streets, and after patrolling the streets, they have to go up to the city wall to inspect the city wall in the direction they are responsible for!

Although the work of these soldiers is not very hard, after all, it is only a patrol, and there is no need to do any physical work, but it is very time-consuming, basically after a whole set of work, the sky will be bright, and they can't be lazy if they want to be lazy.

Of course, this is because the current county lieutenants are at ease and supervise more strictly, and if other county lieutenants are replaced, then whether the city defense work will be slackened is not necessarily.

Li Rizhi asked every captain guarding the city gate, and the replies of these captains were almost all identical, they didn't know who Jiang Laoshi was, and they didn't know this person.

And Li Rizhi asked them to go to the wing room in the yamen to take a sneak peek at Jiang Laoshi, and when these captains came back, they still said that they had not seen this person on the night of the crime.

As for Li Rizhi's question, if someone would climb out of the city wall in the middle of the night, and then cross the moat and run out of the city.

All the captains of the guards shook their heads and said, this is simply impossible, the city wall of Qianfeng County is newly repaired, because this year's year name is Qianfeng, and it is the place where the ceremony of sealing Zen begins, so the city wall is almost the same as the city wall in the Gyeonggi area, and it is completely impossible to turn it out by personal ability.

Li Rizhi asked: "Could it be that when you were taking over the shift, this person happened to pass by you, and you were busy handing over, so no one noticed him?" ”

The captains all shook their heads and said that it was impossible, because they were the most prone to mistakes during the handover, so they had already forbidden pedestrians to enter and exit at the time of the handover, so it was impossible to get out of the city while the handover was over, there was no such possibility.

After questioning these captains, they asked them all to go back, Li Rizhi and Cheng Zizi were silent, these captains would not give Jiang Laoshi any perjury, and it would be good if he didn't make him a criminal.

So according to what these captains said, wouldn't Jiang Laoshi mean that it was impossible to go out of the city to commit crimes, and that he would definitely not be a murderer.

Cheng Zizai said: "Could the murderer be people from the outside, such as those who renovated the Jiang family's house?" ”

Li Rizhi thought for a while, nodded and said: "Of course this possibility exists, maybe someone and Jiang Da Hammer usually have a dirty relationship, and then on the night of the crime, he sneaked into Jiang Da Hammer's bedroom and killed Jiang Da Hammer, which is also very likely."

The key is that the dog raised by Jiang Dazhui's house did not bark on the night of the crime, which means that it must be an acquaintance who committed the crime, and this acquaintance must have come to Jiang's house often, and the relationship should be considered intimate, otherwise the big dog would not have recognized him.

If you want to investigate, then you should start with Jiang Dazhui's acquaintances! ”

Cheng Zizi said: "Starting from acquaintances, this is not a particularly difficult thing, it's just a little bit of a waste of time, we can see first, if there is an acquaintance of Jiang Dazhui, who suddenly left in the past two days, such a person will be the most suspicious." ”

Li Rizhi nodded slightly, the case has reached a dead end, if you want to forcibly go further, then you can only carry out this most time-consuming and laborious investigation, and the effect of the investigation is not very good.

That night, after Li Rizhi had dinner, he sat alone in his study and carefully analyzed the case.

Now that this case has progressed to this point, it seems that it can only be investigated, but it does not seem to be particularly necessary.

Jiang Dazhui is looking for someone to renovate the house for him, and he will definitely not look for those who have had dirty relations with him before, after all, renovating a house is a profitable business, how can he let people who have dirty feelings with him make money?

Unless it is someone who has a dirty relationship with him in the process of renovating the house.

However, Jiang Da Hammer himself is in the stone business, after all, this is a business that has something to do with the construction industry, so the person who gave him to renovate the house, in order to continue to get business in the future, will definitely not offend Jiang Da Hammer.

As for what is dirty, and it has reached the point where he has to kill Jiang Da Hammer, this kind of hatred is almost impossible to appear.

If there is really this kind of hatred, then whether it is the aunt of the Jiang family or Jiang Zhonghou, they will take the initiative to bring it up.

Aunt Jiang will definitely not let go of people who may kill her husband, and she loves Jiang Zhonghou and Jiang Laoshi very much, even if there is only a slight possibility, she is not willing to imagine her two nephews as murderers.

As far as Jiang Zhonghou is concerned, he has been forced to bite his own brother, will he still be polite to others?

As long as it is possible, even if there is even the slightest possibility, he will be bitten, and he will definitely do his best to bite it, and there is no possibility of letting it go.

And Jiang Zhonghou never mentioned such a person, which shows that Jiang Dazhui does not have such a life-and-death feud.

Even if Jiang Zhonghou was asked to make it up temporarily, he couldn't make it up immediately.

In fact, this is tantamount to ruling out the possibility of outsiders committing crimes.

Jiang Da Hammer died in bed, and the murderer entered Jiang Da Hammer's bedroom, and then hit the sledgehammer hard, beating him to death on the bed.

And the Jiang family did not lose anything, which also ruled out that the thief entered the Jiang family to steal something, and was suddenly discovered by Jiang Da Hammer, and the thief killed Jiang Da Hammer in order to extinguish the mouth, which is also impossible.

Jiang Dazhui's death itself excludes that he died in an emergency, and he did not suddenly encounter the murderer and was killed!

Eliminate all kinds of impossible situations one by one, and then the rest of the situation will basically be very close to the truth.

After analyzing this, Li Rizhi understood that the murderer of Jiang Da Hammer must be one of the four people, such as Aunt Jiang, Jiang Zhonghou, Jiang Laoshi, and Beigong Tai!

And these four people all look like it is completely impossible to kill Jiang Dazhu, so who is the real murderer?

At this time, it is already very difficult to solve the case by conventional methods!

Because when the real murderer finds out that the government doesn't have a very good way to deal with him, it is impossible for him to tell the truth.

Because at this time, he only needs to be able to stand up more than others, whether it is when he is beaten, or when he is forced to confess, he doesn't need to be strong, he only needs to be stronger than the other three, so a little bit is enough!

And Li Rizhi's best interrogation method is that kind of interrogation, can you recruit or not? Your accomplices have been recruited, and you are going to recruit them now, so that the punishment can be reduced.

This trick is no longer good, because among the four of them, there are obviously no accomplices.

And like other means, for example, this case can't be solved, the criminal is you, and you don't need to recruit anything, just cut off your head, if you say it's not you, then who!

This trick is not easy to use, because no matter how much they bite each other, they can't climb new tricks.

So what kind of means should be used to solve this case?
