Chapter 17

Everyone was in an uproar.

It's not that they didn't suspect Fang Chenyu and Gao Jichang, but at present, everyone was only discussing the murderer who killed Liu Huaixin. According to the results of their three lines of investigation, the murderer's motive for murder was still unclear. Of course, any acquaintance who was in the building at the time of the crime could have been the culprit.

Fang Chenyu and Gao Jichang taught the same grade as the deceased, so they are of course the most likely suspects. However, this does not rule out the suspicion of the other four teachers and parents.

Li Qingyao's words were too certain, tantamount to asserting that the motive for the murder was related to emotional entanglement. Although Chen Pu also said at the scene that day that this case was closely related to Zhang Xiyu's case, it was only one of the investigative directions at the time and a possibility.

After all, the Zhang Xiyu case happened a year ago. At that time, the Municipal Bureau and the Education Bureau attached great importance to it and closed the case in a low-key manner. Now Li Qingyao said this, which was equivalent to overturning the verdict. Moreover, it also involved a grade leader and a key class teacher in No. 29 Middle School. It was too sensitive. It was foreseeable that the subsequent handling of the case would face huge pressure. No wonder they were in an uproar.

Li Qingyao faced everyone's complicated gazes and was about to speak when he noticed that although Chen Pu lowered his head, there was a faint smile on his cheek and his brows were completely relaxed.

Li Qingyao curled his lips slightly, looked away, and began to state: "I have three reasons:
First, in the semester before Zhang Xiyu's death, her grade ranking in the final exam improved by nearly 100 points, but people around her did not see her studying hard, and she also spent a lot of extra time on Sun Haochen, which was not in line with common sense. On the contrary, she did very badly in the various small tests and monthly exams that followed. Therefore, I suspect that someone gave her the answers to the final exam in advance;

Second, her attitude towards Sun Haochen was very strange. If she just had a boyfriend who was a college student, was it necessary to keep it secret to that extent? She didn't even tell her best friend. I don't think she was afraid of being found out for premature love, but she was afraid of something else. Sun Haochen also confirmed that Zhang Xiyu's brand-name clothes were bought by someone else, and that she had sexual experience and was familiar with the nearby reasonably priced hotels. But no one knew who this person was, which meant that this person's identity must not be exposed;
Third, several of her besties and Sun Haochen mentioned that Zhang Xiyu had emotional problems, moodiness, and depression all day long. From their descriptions, it was clear that her mind was not on studying and she didn't care at all. I suspect that during that time, there was a huge problem in her relationship with that person, which was the main reason for her emotional breakdown and jumping off the building, not the study pressure written in the case report.

Combining the above three points, this person is a male that Zhang Xiyu can come into contact with in her daily life, has financial resources, is an adult who can take her in and out of regular hotels, can get the answers to the final exams of various subjects, and his identity cannot be exposed. Among the six suspects, only Fang Chenyu and Gao Jichang meet the requirements. "

Everyone was silent. Firstly, the amount of information Li Qingyao mentioned was too much; secondly, the evidence she mentioned was scattered all over the transcript, so everyone was searching for it and thinking about it.

"Do you agree with everything she said?" Chen Pu's cold voice sounded. Li Qingyao glanced at him, and the smile he had before disappeared. Captain Chen regained his poker face. Li Qingyao really wanted to know, was he in favor of her, or against her?

"I have doubts." Fang Kai raised his hand. When he raised his hand, everyone listened attentively. Fang Kai said seriously: "I think the three points you mentioned are all possibilities and speculations. There is no definite evidence. When we investigate a case, we must talk about evidence. I can refute you one by one now:
First, you infer that someone gave her the answers, and from that you infer that person was the teacher. But I can also infer that she cheated on the test by herself or with the help of other students. So the first point is not true;

Second, Zhang Xiyu was under too much emotional pressure. Perhaps because of this, she didn't dare let anyone know about Sun Haochen's existence. After all, people with psychological problems cannot be judged by common sense. As for whether she was a virgin, it was just Sun Haochen's one-sided statement. She could have also gone to find out about those hotels in advance. As for those clothes... I really can't think of them. I can check, but I can't conclude that they were given by my lover, right?
Third, classmates all said that she didn't care about grades, so you inferred that she had other sources of pressure. I read the transcripts from last year. Her family put a lot of pressure on her. There was something wrong with their education. What if she really cared about grades and committed suicide by jumping off the building, but she just didn't show it normally? Aren't many minors like this?
If it is just the reasons you just mentioned, I cannot agree with it. "

Everyone looked at each other in bewilderment. The newcomer was embarrassed. But Fang Kai was not the easy-going big brother when it came to the case.

Yan Yong had already leaned towards Fang Kai. He felt sorry for Li Qingyao's silence. He scratched his head and subconsciously glanced at Chen Pu, only to find that Chen Pu also looked serious. He thought to himself, "It's not good. The boss has always been hard-hearted. When he was a newcomer, he was scolded and cried several times. Is Chen Pu going to take action against Li Qingyao now? Such a well-behaved and honest girl, she won't cry, right..."

Sure enough, Chen Pu said, "Okay, let me tell you..."

"It's more than that."

Li Qingyao's voice and Chen Pu's voice sounded at the same time, and Chen Pu stopped talking and looked at her.

To everyone's surprise, Li Qingyao's expression remained calm. She said, "It's like this. I didn't finish explaining it just now.

Yesterday at No. 29 Middle School, I specifically learned about their final exam system. It is very strict. First of all, the classrooms are changed, and four teachers are invigilating in each classroom. Students sit according to their ranking. I also looked at Zhang Xiyu's ranking table for that exam and the scores of people around her. There were dozens of poor students who were dozens of places lower than her. I also looked at her scores in each subject. The three subjects with the highest scores were mathematics, physics and English. These three subjects have the most multiple-choice questions, and even if you cheat and look through the books, you can't find the answers. And mathematics and physics were her worst subjects before. So I think that she had no one to copy from and nowhere to copy from, so it is most logical to memorize the answers in advance.

The second point is whether her secret lover exists. I think Sun Haochen does not need to lie. From our conversation with him, we can see that he is a person who cares a lot about face. One of the purposes of dating a high school girl is to find a virgin. There is absolutely no need for him to lie and cuckold himself. He has no interest in this case and no motive to lie.

In addition, I went to Zhang Xiyu's home early this morning. Her mother was quite cooperative and kept all her clothes. I found that she still had many brand-name underwear, all adult brands, some of which cost 200 to 300 yuan each. Her mother didn't know those brands at all and didn't know their value. I don't think any ordinary friend would give her so many brand-name underwear, except for a lover.
