According to Yang Qianfeng's opinions, Zhang Lihua strengthened the work in these aspects: first, concentrate on the main efforts to investigate all the vehicles that passed through the toll station and passed through Jinshui County on the night the suspect dumped his body; the second is to expand the scope of assistance in the investigation to find the source of the corpse; The third is to retrieve mobile phone information and screen the data.

Hong Lifei's mood is as Zhang Lihua said to Yang Qianfeng is very anxious, he is anxious not only because of the continuous murders, but because he has been to the Jinshui County Public Security Bureau for a few days, obviously feels that the criminal investigation team has insufficient stamina, this group of people rush to kill and kill has nothing to say, and the enthusiasm and initiative of the work are also good, but the criminal investigation work must not only be brave, but more importantly, it is necessary to be strategic, and can dig out the cunning criminals hidden in the depths of the crowd and bring them to justice. Except for Zhang Lihua and Zhou Jie at the case analysis meeting, no one else could say anything, let alone put forward new and constructive opinions, especially Captain Gao Limin, although he had done criminal investigation many years ago, his thinking of investigating and solving cases had seriously failed to keep up with the development of the situation, and the way of thinking of leading the team was still in the post of director of the police station, which did not conform to the management of the criminal investigation team, especially the management of the team after the criminal investigation reform. Therefore, Shi Lei sent criminal investigators like Yang Qianfeng to work in the Civilization Office, and he had a lot of opinions. But Shi Lei is now the deputy county magistrate and the senior party official and director of the Public Security Bureau, and besides, in addition to the director of the county-level public security organs, other personnel issues are the affairs of the Jinshui County Party Committee and the Party Committee of the Public Security Bureau. In addition, Yang Qianfeng's work achievements have also been fully affirmed by the county party committee and government, and he was soon promoted to a leading cadre at the department level.

Hong Lifei went to the scene to see the two murders that occurred in Jinshui in a row, and he knew the specific facts of the case, and many scouts thought that the street murder case in Langshu Town was easier to solve than the female corpse case on the national highway, but he didn't think so. He thinks that relatively speaking, there is more work that can be done in the street homicide case in Langshu Town, after all, the victim is local, and it is enough to do work around the victim or find the murderer on the spot, which makes people feel that this case is easier to solve, but he knows very well that this case is not so simple, it is not a murder of passion through the scene, the living conditions of the victim's family are not good, and it is impossible to kill him for money, and he has not heard that he has an unclear relationship with any woman outside, so the possibility of being killed for love is not great. In the end, why did the murderer want to kill him, to say vendetta, and the victim did not have a contradiction with the person, so it is still difficult to determine the murderer's motive for the crime, and from the analysis of the scene of killing him, the murderer should have been premeditated, otherwise there could be no clues at the scene; The key to the female corpse case is the source of the corpse, and if the source of the corpse cannot be found, the case cannot be further deepened. He believes that these two cases are very difficult, and he has no idea whether they can be solved, so he has set the goal of trying to solve one case. Of course, as a leader, this kind of thinking can only be kept in his heart, and it is impossible to say it, otherwise it will directly affect the morale of the combatants.

On the afternoon of the second day after the meeting of the city bureau, Hong Lifei rushed to Jinshui County again. On the way, he wanted to go directly to the Hammer Task Force, but when he arrived in Jinshui County, he still went to the "Three. The "Three Dumping of Corpses" task force went to take a look.

"III. The "Three Throwing Corpse Case" task force is set up in the criminal police team of the Sunshine Responsibility Area, and the criminal police team of the Sunshine Responsibility Area is on Hongsu Road in the urban area, which is a four-room four-story building, and the front of the building is Hongsu Road, and the back is a closed large courtyard, and the right side of the building is a road, so the first floor is a façade room for doing business, and the second floor should be walked from the right side of the road, because the courtyard behind this road has opened a gate, and the criminal police team in the responsibility area rents the third to fourth floors of this building and the courtyard behind it. The sign of the criminal police team is hung at this gate.

The fourth floor is the rest and living area of the criminal policemen, the second and third floors are the office area, and the headquarters of the special case group is in the small conference room on the third floor, where Zhang Lihua, Xu Yan, and others are sorting out the mobile phone information retrieved from the telecommunications department. Everyone else was sent out to check the suspicious vehicle.

Hong Li flew into the courtyard and went directly to the third floor, and saw that the conference table was full of mobile phone information sheets printed from the telecommunications department, Zhang Lihua and the other four people were burying their heads in reading the information, and said in surprise: "What are you doing?" So much confidence in the list. ”

As soon as Zhang Lihua and Xu Yan heard that it was Hong Lifei's voice, they immediately stood up at the same time and said, "Hello, Director Hong!" Later, Zhang Lihua reported: "We are analyzing and screening those outsiders who came to our Jinshui County on the night of March 2, but the workload is indeed too much for manual work. ”

Hong Lifei originally left after a turn, but he didn't expect Zhang Lihua and them to think of using this method to investigate the case, and they became interested when they heard it, because he had also thought of using this method to carry out case investigation, but he just didn't figure out the clue, and he didn't know where to start and how to investigate, so he sat down happily and said: "Zhang Lihua, I didn't expect your minds to be enlightened and know how to use scientific and technological means to investigate?" ”

Zhang Lihua smiled and said: "How could I think of it, it was the idea given to me by the Yang Qianfeng Party Committee." ”

Hong Li flew to the chair, patted his hand on the conference table and said, "Did I say it!" Yang Qianfeng should not be transferred to the Civilization Office. After saying that, he felt that it was not appropriate to say this here, so he braked sharply and said: "This is a good idea, it expands our investigation ideas and allows us to find a new way to solve the case." Technology is productivity, and we may be able to find a breakthrough in solving crimes. ”

Zhang Lihua was so happy to see Hong Lifei, and remembered what Yang Qianfeng said, he may have suffered a lot, and he didn't help the case at all, I was afraid that Hong Lifei had too much hope for this, and it would be useless at all, and he would be disappointed. immediately said: "What the Yang Party Committee meant, just let us check and check, and we can't hold out too much hope." ”

Hong Lifei slapped the table again and said: "It's good to think of it, and if you think of it, you can boldly ask you to do this, I think it's amazing, I once thought of this method, but I haven't done it." Whether there is any result or not, you have to do it seriously, this is progress. Do you know what I mean? ”

Zhang Lihua was relieved when she heard Hong Lifei say this, and said with a smile: "We must conscientiously complete this task." ”

Hong Lifei picked up a long list of information and said: "How do you find outsiders from these data, and how do you exclude and confirm them after finding them." ”

Zhang Lihua put down the list in her hand and told her what Yang Qianfeng said to her, and then talked about Yang Qianfeng's request to expand the scope of the investigation on the original basis, and the cars that passed back and forth at the toll booth that night were the key points.

Hong Lifei listened and kept nodding, and after Zhang Lihua finished speaking, he said: "This makes me see the stamina of the Criminal Police Brigade of the Jinshui County Public Security Bureau. ”

Then Hong Lifei and Zhang Lihua worked together, and they didn't go to Langshu Town that afternoon.

Shi Lei came to the conference room when he was about to get off work, Hong Lifei went to the bathroom, and saw that the four people were looking at these lists and said, "Why do you get so many mobile phone information materials." ”

Zhang Lihua talked about the purpose of making so much information, but he did not mention Yang Qianfeng. Shi Lei said unhappily after hearing this: "You guys are doing this all afternoon? Obviously, it was a foreigner who committed the crime, but he just threw the body in our county, so how could the suspect be found on the telecommunications data of our county. ”

Hong Lifei walked in at this time and said, "That's not necessarily! This is an idea that Yang Qianfeng came up with, and I think it is a good way to investigate. ”

When Shi Lei heard that it was Yang Qianfeng's idea, he threw the information he was holding on the table and said, "Do you think it's a waste of time?" ”

Zhang Lihua heard the disagreement between the two leaders, and immediately lowered her head to do her own thing, thinking that it seemed that Shi Lei really hated Yang Qianfeng.
