As soon as the captain gave the order, the members of the task force were of course immediately busy. Li Nan and her partner also received the investigation task, but before dispatching, she thought about it for a while, and still walked up to the team leader Jiang Yunye, and said frankly: "Team Jiang, I know this Teacher Zhang Zhan, I can provide some information about him as a reference for us to solve the case." ”

Jiang Yunye's eyes lit up when he heard this, and he said happily: "Really? Do you know him? This is great, let's talk about it, what kind of person is this Zhang Zhan? ”

Li Nan didn't comment, but just told the truth based on what she knew about the situation of Lu Dao. From how he knew Zhang Zhan through an incident of students retaliating against the teacher at the beginning, to knowing that he was a colleague of his sister's school. From her sister once negatively evaluating this person, to subverting his image through a schoolgirl framing incident. In the end, Li Nan told how this teacher Zhang Zhan had saved her mother's life, and now he has a good relationship with her family, I wonder if Lu Dao needs to avoid suspicion?

Jiang Yunye was silent for a long time after hearing this, and then said with a smile: "A very interesting person, first had a bad reputation in school, and after knowing you, he suddenly changed his image, and appeared in time to save your mother. Don't you think he did this for some purpose? ”

Li Nan was stunned, she didn't understand the meaning of the captain's words at all, and could only ask inexplicably: "What purpose?" ”

Jiang Yunye smiled, patted her on the shoulder and said, "Okay, when I didn't say it." I understand everything you told me. I believe you are a dedicated police officer. So don't shy away from suspicion and get your job done! ”

Li Nan breathed a sigh of relief, turned around and strode out with her partner to start the investigation. Looking at the back of the departing policewoman under him, Jiang Yunye recalled the situation of Zhang Zhan that she said just now, and couldn't help but fall into contemplation again.

It wasn't until after dark that the same feedback came back on the investigation of the suspect Zhang Zhan. The first is the details of his deposits and income and expenses in the bank. Investigators who returned said that Zhang Zhan had only two accounts in the bank, one with the Industrial and Commercial Bank of China and the other with the China Construction Bank. Among them, ICBC has an ordinary card account, and CCB has a credit card account.

In both accounts. The balance of ICBC's ordinary account is only more than 2,000 yuan. The main source of income is Zhang Zhan's salary and bonus as a teacher. The highest balance in history did not exceed 30,000 yuan, the largest expenditure. That's about 10,000 yuan.

Another CCB credit card. The credit limit is 10,000 yuan. There have been several credit card purchases, but the amount is less than 1,000 yuan, and they have been repaid on time afterwards.

Jiang Yunye held in his hand a list of accounts that investigators had pulled out of the bank. While listening to their reports, I also looked at them carefully. He found that around the time of Heipi's murder, Zhang Zhan's bank account did not have any particularly high-profile expenditures. But during the period between Jin Yurong jumping off the building and dying and Fang Xiaoguo being killed, Zhang Zhan's bank account once withdrew 10,000 yuan in cash. And this cash is the largest expenditure in the history of this account.

Although in today's economic environment, 10,000 yuan is really not a lot of money. But the timing of the withdrawal of this money was too coincidental, Jiang Yunye's first reaction after seeing it, he thought that this 10,000 yuan was the commission for Zhang Zhan's hired killer? Otherwise, why would he suddenly withdraw this amount of money from his own account shortly after Jin Yurong and before Fang Xiaoguo was killed?

But after thinking about it carefully, Jiang Yunye found that this inference was a bit too far-fetched. First of all, he suspected that Zhang Zhan was the murderer behind the killing of Fang Xiaoguo, based on his connection with the murder of Heipi. If it can be proved that Heipi was killed by him, then Fang Xiaoguo's death is absolutely inseparable from him. However, on this list of bank accounts, in the period before and after Heipi was killed, Zhang Zhan did not withdraw more than 1,000 yuan in cash at all. There is no evidence that Zhang Zhan hired a murderer to kill Heipi, so how can it be inferred that he was the murderer behind Fang Xiaoguo's murder?

Secondly, although Jiang Yunye didn't know how much it cost to hire a professional killer to kill a person, 10,000 yuan was too little. This money may be able to hire a hooligan to teach an ordinary person with no background, but it is definitely not enough to kill a rich kid with status and the protection of several bodyguards. Even if it's a deposit, it won't be only 10,000 yuan.

And from this Zhang Zhan's bank account, it shows that he doesn't have the strength to hire and kill people at all, not to mention that he can't afford to hire a professional killer, even if he is a local ruffian hooligan, he will not dare to kill Fang Xiaoguo because of 10,000 yuan.

Thinking of this, Jiang Yunye couldn't help frowning deeply, and after thinking for a long time, he asked the investigator who came back: "Is there only these two in this Zhang Zhan's bank account?" Have you checked it carefully? ”

The investigator replied: "Carefully checked, unless he opened an account in someone else's name, there are only these two accounts that match his identity." ”

Jiang Yunye was only helpless when he heard this, nodded and said, "Okay, it's hard work, go and take a rest." ”

After the investigators left, Jiang Yunye lit a cigarette and continued to think while puffing. This Zhang Zhan is just an ordinary teacher, and his income cannot afford to hire killers, especially professional killers. If you can't find out that he has other financial resources, then your suspicion of him is wrong. But this person happens to be related to both Heipi and Fang Xiaoguo, is it just a coincidence?

Soon after, another group of investigators returned. They checked the interpersonal relationship of this teacher Zhang Zhan, and by checking the call records of his mobile phone number in the mobile company, they got the names of the people who had contacts with him.

Jiang Yunye immediately asked them to find out the information of these names through the computer files of the police station, and then the interpersonal relationship of this teacher Zhang Zhan was very clearly displayed. In addition to his parents, there are his colleagues and his students. There are his classmates, and there are some people who can't figure out the relationship.

Among these people, the names of two people caught Jiang Yunye's attention. One is named Qi Zhenni, the deputy general manager of a clothing design company in the city. This person has a lot of phone contact with Zhang Zhan, but she is neither a colleague nor a relative of Zhang Zhan, which is very worthy of attention.

The other is named Shen Guowei. Although this person has little telephone contact with Zhang Zhan, it is known from the computer that this Shen Guowei is actually a retired boxer. Currently operates a boxing club in the city.

So Jiang Yunye pointed to the names of these two people and said, "These two people." It's worth our attention and investigation. This one named Qi Zhenni has frequent contact with Zhang Zhan, and their relationship must not be simple. And the information shows that she is the vice president of a company. Then at least it can be regarded as a high-income group. Check it out. Whether she and Zhang Zhan have any financial dealings. Another Shen Guowei. It's a retired boxing team. Then this person must be extraordinary, maybe the killer we are looking for. Check out what the relationship between him and Zhang Zhan is, and find out on the night Fang Xiaoguo was killed. He has no alibi. If not, then investigate him thoroughly! ”

"Yes!"

The police officers present were very excited, as if the murder of Fang Xiaoguo had begun to clear the clouds, and the moment when the truth was about to be revealed!

Of course, Zhang Zhan did not know that he had been listed by the police as the number one suspect in Fang Xiaoguo's murder, and an investigation into him had already begun. So he still lives a life that is no different from usual, still having a tryst with Qi Jenny at night and going to work normally during the day.

But when I arrived at school that day, I was fine in the morning, and everything seemed to be normal. But when it was almost noon, he suddenly received a call from Qi Zhenni. As soon as she opened her mouth, she asked Zhang Zhan what had happened, why would the police come to her to ask about their relationship?

Zhang Zhan was stunned for a moment, quickly stood up, walked quickly outside the office, and then spoke: "A police officer came to you today to ask about our relationship?" ”

On the other side of the phone, Qi Zhenni hummed and said: "Yes, the two policemen came to my company and asked me several questions, mainly asking how I met you and what is the relationship between me and you." Zhang Zhan, what's going on? Why would the police be interested in my relationship with you? ”

Zhang Zhan groaned for a moment, and immediately understood the purpose of the police. Even the fact that he had a relationship with Qi Zhenni was found out by them, and it seems that he has really been listed as the most suspicious object!

After smiling faintly, Zhang Zhan didn't feel flustered. It's easy to suspect him, but to convict him, you have to have enough evidence. Unless the police can find the house he rented outside and search for the murder weapon and the computer hard drive he recovered. Otherwise, even if he is determined to be a murderer, there is no way to prove it.

And Zhang Zhan's biggest advantage is that no one knows that he has the skills of a professional killer. The police suspected that he hired someone else to kill Fang Xiaoguo, but they would never have thought that the person who killed Fang Xiaoguo was himself!

This cognitive bias is enough to make the police investigate in vain. Where can an ordinary person with neither money nor power find a professional killer and can afford to hire him to kill people? Right?

So after the Zhilu Dao police had begun to investigate him, Zhang Zhan was still calm and relaxed, and did not feel scared or nervous. Instead, he smiled and said to Qi Zhenni on the other end of the phone in a very relaxed tone: "I know what I said, probably because of the case of the murder of the evil young Fang Xiaoguo." You don't know, these police officers also came to our school two days ago to investigate. They believe that the reason why this evil young man was killed was because someone avenged the female student who was killed by him some time ago and jumped to her death. This female student is a student of our school, so the teachers and students in our school who have a relationship with the female student are all suspected and investigated by the police. ”

Qi Zhenni was very surprised when she heard this, and said, "So, you are also suspected of being a murderer by the police?" ”

Zhang Zhan smiled: "Yes, that female student unfortunately happens to be the student I teach, and I am naturally the target of suspicion of the police." ”

Qi Zhenni suddenly realized this, and couldn't help but scold angrily: "These policemen are really mentally retarded and neurotic!" You're just ordinary teachers and students, how can you hire a murderer? People with a little bit of sanity and common sense wouldn't think so, would they? ”

Zhang Zhan smiled, immediately changed the topic, and said: "We can't control what the police think, but they found you and asked about your relationship with me, how did you answer?" ”

Qi Zhenni's voice immediately lowered, and she replied with a soft smile: "Of course I didn't say the real relationship, just said that I am friends with you, and I usually contact you because of some children's education issues." By the way, the police also asked me if I had any monetary dealings with you, what did they mean by that? ”

Zhang Zhan pondered for a while, probably understood, and said with a smile: "These policemen may have checked my bank account." I found out that I didn't have much money, and I couldn't afford to hire a killer to kill people. But they don't give up, so they ask you to investigate. Perhaps, you once lent me a large sum of money, didn't you? ”

At this time, Qi Zhenni also understood why the police would find her for investigation and interrogation, and couldn't help but shake her head and smile, helpless. The two chatted a few more words about this matter, and Zhang Zhan said: "Since the police have already suspected and investigated me, in order not to make more trouble, let's not meet in the past few days, right?" When this is over, how about we be the same again? ”

Qi Zhenni naturally understood what Zhang Zhan meant, and although she was a little dissatisfied, she still agreed. After exchanging words and seeing each other again, the call ended.

As soon as he put down his mobile phone, Zhang Zhan didn't have time to think about anything when another call came in. picked it up and took a look, and found that on the caller ID, it was actually Shen Guowei. Since the beginning of school, Zhang Zhan has not been to the club to practice boxing, and Wang Huili's cousin naturally hasn't had much contact for a long time. Suddenly seeing him calling, Zhang Zhan's heart moved, thinking that the police had also gone to him to investigate?

Hurriedly pressed the call button, Zhang Zhan fed, and sure enough, Shen Guowei's voice came from there: "Xiao Zhang, what's the matter?" A couple of police officers just came over to talk about what case they were looking into and asked you a lot of questions. The strangest thing is that every member of the club, including me, was asked by the police what he was doing between 2 and 3 a.m. on October 11. What are you doing? Did you commit something? (To be continued......)
