Twenty minutes later, Fang Yihong and Qiu Weiping climbed to the top of Xiaosongling, and sure enough, looking down from here, the mansion of Fang Xiaoguo on the mountainside was fully visible, as long as there was a telescope, the movements in the mansion could be clearly observed.

Needless to say, Qiu Weiping understood Fang Yihong, and pointed to her brother's residence below: "That killer must be hiding here to observe the terrain of my brother's house, the side door, and my brother's bedroom, can all be observed from here." ”

Qiu Weiping smiled and nodded, and then began to lean down, carefully inspecting the grass and trees on the ground, and even some garbage. Fang Yihong was very excited, and when she saw Qiu Weiping using a small pair of tweezers to pick up a small piece of cigarette butt on the ground to watch, she immediately walked over and said, "Is this what the killer left behind?" With this thing, can you find out who the killer is? ”

Qiu Weiping groaned: "It's hard to say, in addition to that killer, other people can also come to this place." You see, this place is full of garbage left by people, it can't be done by just one person. What's more, that killer is very professional, and it is almost impossible to leave something behind for us to solve the case. ”

Fang Yihong was stunned for a long time, and said, "If that's the case, then what's the use of us finding the killer's observation location?" It's not the same, I don't know who he is. ”

Qiu Weiping shook his head and said: "It's different, Zhilu said that he had been here before, so we have the direction of investigation." This killer may have seen him when he came here and when he left. It's only been a few days, and it shouldn't be forgotten so quickly. If we're lucky. This may lead to clues to track down this killer. ”

Fang Yihong immediately became excited again when she heard this, and said, "Then why are we still stunned, hurry up and go to the neighborhood to find someone to ask!" ”

Qiu Weiping smiled: "Don't worry, although I don't think this killer will leave anything here, but as a detective, I still have to investigate carefully." Wouldn't it be a pity if something was left behind? ”

Next, Detective Qiu Weiping carefully investigated and searched on the top of this mountain, and some things he thought were suspicious, all of which he picked up and put into a plastic bag. More than an hour later. He and Fang Yihong came down from the top of the mountain. Immediately began to visit some residents near the summit again, asking them if they had seen strangers lingering or loitering at the summit a few days ago.

However, the results were disappointing, and at the end of the day, not only two or three residents on the top of the mountain asked. Even all the residents on the road to the summit asked. But there is no useful information. Modern people are not nosy. There are also very few people who pay special attention to the people who go up or down the mountain. Even if someone has ever seen that killer, it's normal that they can't remember it. In this regard, the great detective Qiu Weiping is also powerless.

After returning to the hotel room in the evening. Fang Yihong, who was extremely disappointed, kept sighing. After Qiu Weiping took a cigarette, he said, "It seems that there is no hope for tracking down the clues of the killer." Next, we can only look for clues from your brother himself. According to your brother's way of life, there must be many people who have offended. I saw that in the police case analysis report, they focused their suspicions on the family and friends of the schoolgirl who had just jumped to her death. I don't know what progress the police have made on this investigation now? ”

At this moment, in the Gaohe City Police Station, the investigation of the murder of Fang Xiaoguo has really made some progress. A person name worthy of suspicion and attention has entered the field of vision of the criminal investigation team leader Jiang Yunye.

This person's name is Zhang Zhan!

The reason for the incident is this, because it is suspected that the death of the female student Jin Yurong is related to the murder of Fang Xiaoguo, so the police have conducted an investigation and statistics on Jin Yurong's relatives and teachers and classmates at the school, and listed the objects worthy of attention and suspicion. So after a busy day, a list of people who are close to Jin Yurong came out. Among them are two relatives of Jin Yurong, three teachers in the school, and two classmates who are particularly good with Jin Yurong.

Then, after a day of preliminary investigation, it was found that there was nothing suspicious about the people on the list. Those two relatives are ordinary citizens who follow the rules, have no criminal records, and are not particularly wealthy in terms of economy.

There are three school teachers, one of whom is Wang Huili, Jin Yurong's homeroom teacher, and the other is Zhang Zhan, the school's English teacher. Needless to say, the head teacher naturally has a close relationship with Jin Yurong. The reason why English teacher Zhang Zhan was included in the list was because Jin Yurong was the representative of the English class in the class before his death, and the police thought that he was naturally a person close to Jin Yurong, so they included him in the list.

The last of the three teachers is actually not a teacher, she is the leader of the school, that is, Sun Xiaoyan, the principal of the third middle school. The reason why Principal Sun is included in this list is because she is the head of the school. When a student at her school was killed, she had reason to be angry and even retaliate.

However, after the background check of the three teachers, nothing suspicious was found. The head teacher Wang Huili's family is innocent, and she has never violated any law. A weak woman is unlikely to do such a thing as buying murder.

The English teacher Zhang Zhan is a man, but this person is also an ordinary person who follows the rules. Both parents are employed, and he himself has no criminal record. On the economic side, nothing unusual was found. A teacher's salary is enough to support himself, but when it comes to hiring killers, it seems to be a little reluctant.

The one with economic strength is Sun Xiaoyan, the principal of the school. It is found that she has a house and a car, and she should be able to afford to hire a killer. However, after finding out, it was found that her husband was the executive vice mayor of the city, would a woman with such status easily hire and kill?

The last are the two classmates who are good friends with Jin Yurong, children who are only fifteen or sixteen years old, and there is really nothing to doubt. Even if they have the intention of avenging Jin Yurong, where do they have the ability to hire and kill people?

So after checking it, almost all the people on the list have nothing particularly suspicious. For a time, the investigation of the case was about to reach an impasse.

But at this time, a male policeman who had just gone out to track down clues about the killer came back and saw the list, and when he saw the name Zhang Zhan, he felt a little familiar. After thinking about it for a long time, he asked Li Nan, the policewoman who came back with him: "This Teacher Zhang Zhan, is it the same Teacher Zhang who came to ask and checked when we investigated the case of Heipi last time?" ”

Li Nan was picking up the teacup to drink water, and when he heard this, he glanced at the list in the colleague's hand, then nodded and said, "Yes, what's wrong?" ”

Before the male policeman could speak, Jiang Yunye, who was pondering on the side, suddenly raised his head sensitively and said, "Does the case of the black skin have anything to do with this Zhang Zhan?" ”

The male policeman was stunned for a moment, and then replied: "Yes, this Teacher Zhang is one of the people who has been bullied and beaten by the black skin. After Heipi was killed, Li Nan and I went to the door to ask him, but we didn't find any doubts, and some people proved that he didn't have the time to commit the crime. ”

When Jiang Yunye heard this, not only did he not have a look of disappointment on his face, but he seemed to be a little excited and excited. He suddenly stood up from his seat, waved his hand, and said, "Find out the investigation record and I'll take a look, quick!" ”

Although the male policeman didn't understand why the captain was interested in this Teacher Zhang all of a sudden, he didn't dare to be careless when he saw that he was so excited, so he hurriedly agreed, and hurriedly ran to find the inquiry and investigation records about this Teacher Zhang Zhan in the black leather case. Li Nan next to him saw this scene, so he asked Jiang Yunye: "Captain, do you suspect that this teacher of the third middle school named Zhang Zhan is the one who bought the murderer to kill Fang Xiaoguo?" ”

Jiang Yunye said: "It's hard to say, but it's definitely worth investigating." You think, the death of the black skin is definitely not killed by an ordinary person. And Fang Xiaoguo's killing was confirmed to be committed by a professional killer. The two cases seem to be unrelated, but the modus operandi is similar, and the victims were both killed by cutting their throats with sharp weapons. If we assume that both cases were done by the same person, what does it mean that there is one person that we find to be involved in both cases? Do you understand? ”

Jiang Yunye said this, and Li Nan naturally understood. But she knows Zhang Zhan, although she has always had no good impression of him, but she is a little disappreciative of Zhang Zhan as the culprit behind these two murders.

Thinking of the image of Zhang Zhan in his mind, Li Nan was about to say something, when Du Tianwei, the policeman who had just gone to look for the investigation record, came back like a gust of wind, holding an investigation record form in his hand, handed it to Jiang Yunye and said, "Captain, I found it, this is it!" ”

Jiang Yunye took it and looked at it a few times, and then after asking Du Tianwei two questions, he nodded, then clapped his hands, and after attracting the attention of all the team members in the office, he said loudly: "Okay, everyone has work to do." Zhang Zhan, an English teacher at No. 3 Middle School, we found out that he had something to do with the murder of Heipi. He was seriously suspicious, and successively hired murderers to kill Heipi and Fang Xiaoguo. Now I ask you to act immediately, and I want to know everything about this man, including his life experience, his recent movements, his personality and personality, the friends he has made, his family and kinship, and so on. In addition, I also want to know the amount of money he has deposited in various banks, as well as the details of his income and expenses in the bank account in the past six months, whether he has borrowed money from others, whether he has any other income other than salary, etc. In short, everything related to this person, I want you to investigate clearly. Time waits for no one, the one-week deadline is coming soon, everyone work hard and act immediately! (To be continued......)
