After Gao Limin and Zhu Dong returned to the Public Security Bureau from the Civilization Office, they immediately asked Xu Yan to take out the case materials from the filing cabinet seven years ago, and they compared the photos of the deceased at the two scenes.

If you can join the case, there is hope of solving the case, Gao Limin excitedly called Zhou Jie to Xu Yan's office, and asked him to confirm it again, Zhou Jie was happy after comparing it, and said: "Captain Gao is really good, why did he suddenly think of merging with this case, good things, the previous case was difficult to find the source of the body, and now the injured person in this case is a local, which means that the murderer must be in Langshu Town, or not far from Langshu Town." ”

Zhou Jie's praise made Gao Limin very uncomfortable, because after all, he didn't think of colluding and merging the case, but Yang Qianfeng had already told him, don't mention him, so he frowned and said, "Then who is this murderer?" Listen to Yang ....... He still mentioned Yang unconsciously, and when he said the word Yang, he immediately changed his words and said: "I heard that the Yang Party Committee asked you to keep an eye on this case when you were in the brigade, and a lot of work was done around Li Wanqiu and Li Lisheng in the later stage. ”

Zhou Jie was very excited, and after calming down, he introduced the whole situation to Gao Limin and Zhu Dong in detail.

After listening to this, Gao Limin asked: "Why didn't the Yang Party Committee ask you to interrogate and interrogate Li Wanqiu and Li Lisheng at that time?" ”

Zhou Jie said: "When you handled the Nan'an Wu murder case, you participated from beginning to end, so you also know a little about his style of handling cases, and he will not easily pass it on without evidence or until he is not hot." He did not participate in the investigation of this case, but only studied the materials repeatedly, and usually paid attention to this case, as long as there were people outside discussing the issues mentioned in this case, he had to figure it out, Li Wanqiu and Li Lisheng were the ones he heard some discussions, combined with the study of the materials, identified as the key suspect, and determined the investigation measures, let me investigate step by step, but unfortunately I have two things that have not been clarified: one is that the source of the corpse has not been clarified; Second, the former director of the neighborhood committee of Langshu Town has not been found, and some things cannot be determined. These two things have not been clarified, they did it, and they did not admit it, and we have nothing to do with them, I think the decision of the Yang Party Committee at that time was right? ”

Gao Limin nodded and said, "It makes sense, so where is the family of the director of the neighborhood committee?" ”

Zhou Jie said: "I don't know, I found many people to understand him, but no one knows." However, after the Yang Party committee left, I didn't pay attention to this matter anymore, and I don't know if there is any news about his family now. ”

After listening to this, Gao Limin couldn't sit still anymore, and took Zhou Jie, Zhu Dong and others to the criminal police team of the responsibility area stationed in the Langshu Police Station. Zhu Dong looked through the case materials again, and confirmed that Li Wanqiu, Li Lisheng and others often do business outside together, Li Laiwang and the two not only did not contradict each other, but also had a good relationship, and they also did business together for several years, but in the past six months, Li Laiwang has not done business with them anymore, and the materials reflect that the main reason is that Li Laiwang does not do it because he thinks he can't make money, although they don't have a partnership anymore, they sometimes come and go, and it seems that the relationship is still good, and there is no abnormal phenomenon between them. In addition, before Li Laiwang's case occurred, Li Wanqiu and Li Lisheng were doing business in Province F, and they went home at noon on the day of the crime. Therefore, in the first round of investigation, it was believed that Li Wanqiu and Li Lisheng had no motive to commit the crime, so they were directly excluded and no further in-depth investigation was carried out against them.

Yao Changsheng rushed directly to Langshu Town after having lunch at Yang Qianfeng's place, organized a meeting of the special case team, studied the specific methods and steps of the next step, and in addition to conducting an in-depth investigation around Li Wanqiu and others, he also drew on the experience of solving the case of throwing corpses, and decided to extract the mobile phone information of the two people and conduct research and analysis; And continue to find the former director of the Langshu Street Neighborhood Committee. As soon as the case analysis meeting ended, all the members of the special case group immediately took action and carried out their work separately.

After two days of work, it was found out that Li Wanqiu and Li Lisheng had been doing business in recent years, there were originally six partners, Li Laiwang withdrew half a year ago, and there were five people, in addition to Li Wanqiu and Li Lisheng, one of the other three people was Jiang Yangyang of the adjacent Chengguan of Jinyang County; One is Hong Libao from Langshu Town, and the other is Hong Xiaoliang from Langshu Town. Although the five people do business together, they rarely go out together, after the supply of goods is good, if it is done in Jinshui County, under normal circumstances, Li Wanqiu and Li Lisheng go out with the goods, if it is in Jinyang County, they will bring Jiang Yangyang with them. After further investigation, it was found that Li Wanqiu and Li Lisheng sometimes went out to do business, but sometimes they went out not to do business, but to go out to play. Before Li Laiwang was killed, they went to Province F to play for five days.

In addition, after investigation, it was found that Li Wanqiu's business in '96, '97, and '98 was quite good, especially Li Wanqiu and Li Lisheng made a lot of money, and the two families also built small buildings, but they didn't make any money in '99. The special case group held that it was normal to have profits and losses in business, and that it had nothing to do with the case, so it did not pay attention to it, and did not conduct an in-depth investigation into their affairs in this regard, so it did not account for the real income and expenses of Li Wanqiu and others.

But I still can't find the director of the original neighborhood committee. Just as the task force's confidence was waning more and more as it investigated, Hong Yong, a distant relative of Li Laiwang, suddenly came to the task force, and Yao Changsheng and Gao Limin personally received him, and he reflected: "This year's Chinese New Year, Li Laiwang came to my house to pay New Year's greetings, and Zhu Laiwang was drunk that day, so I asked him what was going on. Unexpectedly, he told me that several people who are not business people can make money. I was puzzled to say, didn't Li Wanqiu and Li Lisheng both earn money to build a new house? He laughed and said that the money was not earned by doing legitimate business at all. As soon as I heard this, I didn't understand it even more, so I asked him if the money was not earned by doing legitimate business, but was it still earned by doing improper business? As soon as I said this, he suddenly stopped talking, and no matter how I persuaded him to drink, he stopped drinking, and after a long time he said that it was a secret business and could not be told to anyone, and after a while he fell asleep on the table. You have worked in the Public Security Bureau for so long and have not caught the murderer, so I wonder if Li Laiwang's death is related to some secret business. ”

The situation that Hong Yong reacted to undoubtedly strengthened Yao Changsheng and Gao Limin's suspicion of Li Wanqiu and Li Lisheng, and also increased their confidence in colluding and merging the case, but Yao Changsheng asked Hong Yong puzzled: "It's been so many days since the case happened, why did you only react to this situation now?" ”

Hong Yong rubbed his hands and said embarrassedly: "I actually wanted to talk about it for a long time, but there is no evidence at all for this matter, and besides, Zhu Laiwang drank too much and said it, he may not even remember what he said when he woke up, I have always wanted to reflect, but I am afraid that you will not believe it and think that I am talking in my dreams." ”

Yao Changsheng smiled and asked, "Then why are you still here?" ”

Hong Yong sat up straight and said: "Zhu Laiwang's parents are gone, and there are no brothers and sisters, just one person, you have worked day and night for this case, and you have suffered for a long time, and the case has not been solved, which shows that this case is not so simple, after all, I am Zhu Laiwang's relative, he was killed by someone for no reason, I can't be indifferent, no matter whether it is useful to say this to you today, it is better to say it than to put it in my heart, I always want to say it to you Maybe it will be useful!" That's why I'm here. ”

Yao Changsheng nodded and said, "It's good for you to do this, and contact us in time if you hear or see anything in the future." ”

After Hong Yong left, Gao Limin walked back and forth in the office, repeatedly saying in his mouth: "Improper business, improper business ......," and after saying it more than a dozen times, he asked Yao Changsheng: "Yao Ju, what do you think is an improper business?" ”
