Shi Lei's words in the hospital have been very clear, the gun that injured him must continue to be investigated, of course, he doesn't say it, Yang Qianfeng and the case-handling personnel also know that the source of the gun illegally held by Wang Dajun must be investigated.

On the fourth day of the net collection operation, Yang Qianfeng took Zhang Lihua and Yi Zhonghua to the labor camp to interrogate Zhang Libing, and brought photos of Huang Guniu and Wang Dajun for him to identify.

After so many years of labor reform, Zhang Libing is no longer as arrogant as he was back then, and in general he is very cooperative with Yang Qianfeng and their work, but he really doesn't know the person who bought the gun from him back then, and after looking at the photos of Wang Dajun and Huang Guniu, he determined that it was definitely not these two people, and after he recalled again, it was determined that this person's accent must be from Jinshui County, because he spoke Mandarin with a Jinshui accent, and the others were similar to what he spoke back then, only describing the person's height, hairstyle, and what he was wearing at the time. Originally, Zhang Lihua wanted to draw a picture of the man who bought the gun based on his memory of his face, but his memory of that person's face was very vague, and he couldn't explain it clearly at all, and in the end he found nothing.

After returning from the labor camp, Yang Qianfeng and Zhang Lihua respectively took people to the detention center to personally interrogate Huang Guniu and Wang Dajun, and the confessions of the two were basically the same, saying that Huang Guniu had bought the gun and that the money was borrowed from Wang Dajun, and that Wang Dajun did not know anything about how he bought the gun.

Huang Guniu's specific confession said: "One night after returning from prison, I met a foreigner at the Jinshui bus station, and the man asked me if I wanted a gun, which startled me at the time, and then I quickly calmed down and thought that this person was joking, so I also joked with him and said, 'If you dare to buy it, I will dare to ask for it.'" The man really took out a real pistol from his bag, I didn't believe it was true, so he said show me, and the man took off the magazine and handed the gun to me, and I took a closer look at it and it was really a real guy, and I was very excited, and I liked this gun so much, so I asked him how much it was, and he said four thousand yuan, and I said it was too expensive, and he said you really want three thousand eight, if you don't want it, forget it, and the man said and put the gun from my hand and put it in his bag, and wanted to go, I liked this gun too much, so I pulled him and said, 'Three thousand, I'll buy it for 3,000. The man stopped and looked at me, and said, 'I really want three thousand five, and I won't buy any less.' I gritted my teeth and said, 'Okay, three thousand five is three thousand five, you wait for me, I'll go get the money.' I knew that Wang Dajun had just sold his house and had a lot of money on him, so I went to him and borrowed 3,500 yuan to buy it, it was a pistol, 40 rounds of ammunition, and then Wang Dajun and I went to the mountains to test the gun, and each of us fired five bullets, and there were 30 bullets left and it didn't move. Because the public security organs have been investigating the gun so closely in recent years, Wang Dajun did not allow me to take it out, so I kept the gun hidden at home and did not dare to use it. It wasn't until the Public Security Bureau was going to arrest Wang Dajun that Wang Dajun called him to take the gun to their steel warehouse, but he didn't know that the Public Security Bureau was going to arrest him before the call, so he took the gun to ............. ”

After repeated interrogations by Yang Qianfeng, Huang Guniu said this repeatedly, and insisted that the person who sold the gun was a foreigner, and certainly not from Jinshui County, and as for whether what he said was true or false, only he himself knew. And his description of this person's physical characteristics is completely different from what Zhang Libing said, saying that the person who sold the gun was about 1.6 meters tall, with a round face, not fat, but he was very strong.

Therefore, for the time being, the source of the gun can only be determined according to the circumstances confessed by Huang Guniu.

Recently, the main energy of the criminal police brigade is to handle and guide other departments to handle the six gang cases of the wolf eradication operation, the first week of the net collection operation of the criminal police brigade is basically the participation of all the police, the second week began to fix a special person, after a month of hard work, finally all the six gangs all the things are clear, the next step is to close the case.

After the wolf eradication operation was closed, the public order situation in the urban area and even in the county improved markedly. The improvement of the public security situation has also temporarily relieved the public security police, who have been overloaded.

At this moment, the county documents came down, and Gao Li polled the detention center as the director, and Su Laining transferred the criminal police brigade as the captain.

Since Yang Qianfeng was in charge of criminal investigation work, although Gao Limin was very busy, he felt that he had never been full, and the mood that had been unsmooth suddenly became smooth, speaking from the heart, he recently regretted that he was eager to let Zhang Lihua report to Yang Qianfeng that he was leaving the criminal police brigade, and he thought that following Yang Qianfeng was really energetic, very fulfilling, and could improve himself in all aspects.

Of course, regret only regrets, he also knows that it is okay for him to be the deputy of a criminal police brigade, and there is indeed a big gap between wanting to be a good chief officer, especially if he wants to be like Yang Qianfeng when he is the captain. So he happily accepted the organization's decision and went to work in the detention center.

Yang Qianfeng believes that the main business of criminal investigation work is to solve cases, and all basic criminal investigation work, and even a lot of public security management work are for the purpose of preventing crime and serving the investigation and solving cases, so as the captain of the criminal police brigade, although the main energy is to solve cases, the place should be high, and the overall concept should be strong, and the role of the business guidance department should be given full play, not only to do a good job in the basic work that the brigade should do. It is also necessary to guide all actual combat units to strengthen the construction of basic work, and only when the basic work is firmly established can it be more conducive to raising the overall level of criminal investigation work and increasing the rate of solving cases. If the basic work is a mess, and if there are cases where the ears are deaf and the eyes are not clear, and they do not know what to say, and they all rely on temporary clinging and trying their luck, then we can only fight a passive battle in the face of many cases, especially for those premeditated crimes, it is very difficult to win in one fell swoop, and the possibility of losing the battle is very .......

Su Laining originally admired Yang Qianfeng very much, and besides, he had also been engaged in criminal police for many years, of course, he understood what Yang Qianfeng meant, and as soon as he took office, he changed his role, stood in his own position, and immediately began to grasp the team and lead the team. At the same time, the case of the six gangs in the wolf eradication operation was also successfully concluded, and all work entered normal operation, and Yang Qianfeng was very satisfied with his work.

Su Laining saw that the previous case was basically digested, and in his free time, he specially flipped through the files of the two murder cases in Langshu, conducted serious research and analysis, and formed his own initial thoughts, so he called Zhang Lihua to report to Yang Qianfeng.
