It was already three o'clock in the morning after the meeting, Yang Qianfeng was not worried about others taking the case, and thought that Zhang Lihua was the best candidate for the organizer of this case, so he asked everyone to hand over all the materials to Zhang Lihua, of course Zhang Lihua knew and understood Yang Qianfeng's thoughts.

The policemen all went to rest, Yao Changsheng, Wang Qingbo, Gao Limin and Yang Qianfeng were still looking at the case materials that everyone had just handed over to Zhang Lihua, Zhang Lihua said to Yang Qianfeng while sorting out the materials: "At present, these key people are really difficult to handle, they can't be excluded, and it is difficult to investigate." ”

Yang Qianfeng said with the same feeling: "Yes! As he spoke, he suddenly thought of a psychological test and asked Wang Qingbo: "I heard that the lie detector is very advanced now, especially the exclusion rate is very high, do we have one in our area?" ”

Wang Qingbo didn't expect that Yang Qianfeng's concept of solving cases with science and technology was still very avant-garde, so he put down the materials in his hand and said: "We don't have this kind of equipment in our area, and we haven't used it in case handling. I heard that the H City Public Security Bureau has it, if not, we can give it a try. ”

Yang Qianfeng happily looked at Yao Changsheng and Wang Qingbo and said: "That's what I think, if our work has not progressed, then we will ask them to help us do a psychological test on a few key people." ”

Deputy Director Yao nodded and said: "It is a good case-handling measure, and we should also keep up with the development of the scientific and technological situation to change the way of handling cases and increase our case-handling measures." After speaking, he frowned, thought for a while, and said: "I forgot what the name is, there is a female policeman surnamed Fan in H City who is doing this work." ”

Zhang Lihua glanced at Yang Qianfeng and said in surprise: "Fan Meihua? ”

Yao Changsheng pointed his finger on the table and said: "Yes, yes, yes, it's called this name, once when I went to their detachment to handle the case and talked about this matter, their detachment leader mentioned her, and she had just come back from studying at that time. ”

"You know?" Wang Qingbo glanced at Zhang Lihua and then said: "It would be better if we knew each other, I asked our detachment leader to contact their detachment leader and ask her to come over." ”

Yang Qianfeng said happily: "Okay! Three more days of work, if there is no progress, it will be very hard. ”

Zhang Lihua glared at Yang Qianfeng and said, "Speaking of Fan Meihua, I look at you very happy." ”

Yang Qianfeng knew that Fan Meihua fell in love soon after coming back to Jinshui, her boyfriend was the son of a leader of the county party committee, working in the H municipal government, when she got married, Yang Qianfeng's family of three, Zhang Lihua and Phoenix all went, and soon after marriage, she was transferred from the Z County Public Security Bureau to the criminal police detachment of the H City Public Security Bureau, and the last time they met was when she was transferred to H City for half a year and then Jinshui participated in Phoenix's wedding, and then she just heard her sister who married to Tieshan Township say that she gave birth to a son in the second year of marriage, but I didn't expect her to be engaged in this work now, smiled at Zhang Lihua and said, "Of course I'm happy, having her to help will definitely get twice the result with half the effort." ”

Wang Qingbo heard the words and said jokingly: "It seems to be a beauty!" Listen to what Zhang Da means, Captain Yang and her past still have a story? ”

Zhang Lihua nodded with a smile and said, "The story is there, but it is very pure. ”

Yang Qianfeng shook his head and said: "Wang Da don't listen to her, there is no story, but she cooperates well at work." ”

At this time, Gao Limin read several materials related to his next work and said: "This Li Tianshui has not come back much in the past year, and the people in the village also said that he occasionally comes back to play and leaves, and never lives at home, is it meaningful to focus on investigating him?" ”

Because Gao Limin has a better understanding of the situation in this area, and there are many acquaintances, so when the meeting was held just now to adjust people, Yang Qianfeng handed over the task of investigating Li Tianshui to Gao Limin, according to the current situation, Yang Qianfeng knew that Gao Limin was telling the truth, but he was always uneasy about this person in his heart, and said: "Whether it is meaningful or not, I think we should fully grasp his activities, because he is in Sunshine City, not very far from the scene of the crime, and he is a person who is not doing his job, what if he comes back occasionally this time?" ”

Gao Limin thought that there was nothing possible if the case was not solved, and Yang Qianfeng had no choice but to say: "Then continue to investigate!" In fact, he thought in his heart that this case would never be done by Li Tianlai, but it is true that this person is very cunning, because when he handed over to the former director Li Yiping, Li Yiping specially talked about Li Tianlai, saying that this person is very ghostly, he usually marks the door of the house with long hair every time he goes out, if the hair is gone, it means that there has been someone in the house, and he does not sleep on the bed in the summer, but sleeps on the cool bed in the stove room, when he was arrested, he slept in the stove room and jumped out of the window to escape, in fact, he did not run far, Later, sometimes he went home for one night at night, so he reminded him to pay attention to this person in the future, but after he was transferred, no one reported that he had any illegal behavior, and he had not seen this person, but this time there was a case, and the village cadres listed him.

The next day, people from all walks of life got up early to continue their work, in order to further do the work, Gao Limin took people to Li Tianlai's house, and found that there was a lot of grass growing in the yard, and the door was locked by a big padlock and there were a lot of cobwebs, thinking that this old boy should not have come back for a long time, and then he went to find people who were close to Li Tianlai to learn about other situations.

Although the scope of the survey is four key villages, but the scope of work is indeed very large, because to verify a matter or a person's activities sometimes have to go out of the township and county, so the people of each investigation team are very scattered, Yang Qianfeng saw that the contact between the groups is very inconvenient, some people follow up the investigation far away and cannot use the walkie-talkie contact, so before leaving in the morning, he discussed with Zhang Lihua and Zhou Jie and decided to equip everyone in the team (including those who were transferred) with a Chinese BB machine, Xu Yan received Yang Qianfeng's call and went to work to handle this matter well, And it was hurriedly sent to the headquarters, and at noon it was distributed to everyone, and every comrade was very happy and energetic, and Gao Limin felt a little ashamed of this, because he had no money to match these things with the police in the station.

After lunch, under the instigation of Su Laining, the leaders of the Linmao Township Government, the Tieshan, Fengshan and Piling Township Governments, the Special Pump Factory, the Tieshan Copper Mine, the Piling Iron Mine and the Magnetic Material Factory respectively brought cigarettes, Fruits and other condolences came to the 8.19 task force headquarters to express condolences to all the police officers participating in the war, so many units came to visit a task force has never been in the past, and there were many condolences piled up in the command center for a while, everyone knows that these units came to see Yang Qianfeng's face, and Yang Qianfeng was not polite to hand over all the smiles to Zhang Lihua for unified custody and distributed to the police officers participating in the war.

At half past twelve o'clock in the evening, the meeting was continued to summarize the situation, and through a day of intense work, I found out a lot of the situation in the four villages, for example, now there are three or four empty houses in each villager group, and the family members have gone out to work, and these houses are locked all year round, and they will not come back for a few days until the Spring Festival. However, none of the circumstances formed a new focus of the case, and in the end, the suspects were still concentrated on Bruce Lee, Fang Erjiu, Bao Shuizi and Li Tianlai. Yang Qianfeng arranged the next step according to the situation reported by everyone.

It's the fourth day of the case, and there is still no substantial progress in the work, except for Li Tianlai, who has not been found, all the people have met, but Bruce Lee, Fang Erjiu and Bao Shuizi still have no way to rule it out. Before the meeting in the evening, Yang Qianfeng asked Deputy Director Yao for instructions and decided to ask Fan Meihua to come over to help, and determined that there were six people in the criminal police brigade, two people from the Bei'an Wu Police Station specialized in attacking this case, and the others went back to do other work, because at the same time as the case was detected, there was another theft case in the city, and there was also a case of fighting due to disputes in Bei'an Wu that needed to be dealt with, and there was no need for so many people to be done after the 8.19 case was basically completed. So at the meeting, Yang Qianfeng announced these two decisions, and then arranged the work according to the existing people.

That night, Wang Qingbo reported the situation to his detachment commander, and soon the detachment leader called back and said that he would come over tomorrow after contacting him.

The next day, Fan Meihua went to the Jinshui County Public Security Bureau, accompanied by Xu Yan, to the headquarters of the 8.19 case task force, Yang Qianfeng, Zhang Lihua and Fan Meihua have already become good friends, and the reunion of good friends after a long absence is naturally very affectionate, which makes Wang Qingbo and others very jealous.

Originally, Fan Meihua thought that the countryside would definitely not work, and she had to go to the city to do it, but the Southern Hotel found that this was really a paradise, and all the work could be carried out here, so she discussed with Yang Qianfeng and decided that Bruce Lee would be locked up in the detention center to do it in the city, and Fang Erjiu and Bao Shuizi would be tested at the Southern Hotel.

Everyone hoped that one of the three people could be sure that one of them was the perpetrator, but after testing, the last three people were all ruled out, which made the vast majority of the police in the task force feel very disappointed, especially Fang Erjiu, he not only had the time to commit the crime but also the motive for committing the crime, and everyone suspected him more than Bruce Lee, and some police officers had doubts about polygraph technology and thought that this thing was not accurate.

After Fan Meihua completed Bruce Lee's psychological test, she returned to the headquarters of the 8.18 task force, and Zhang Lihua jokingly said to Fan Meihua: "Is this polygraph instrument accurate?" ”

Fan Meihua smiled and said, "You don't believe in science? Then I'll test it for you and convince you. ”

Because Zhang Lihua also thought that Fang Erjiu's crime was very suspicious based on her experience in handling cases, she always felt uneasy after a test, so she said: "Okay! How to test I'll listen to you. ”
