Gate of Mensa

In the conference room of the Criminal Police Team of the Municipal Bureau, Chen Guojun was organizing a meeting for everyone.

Chen Guojun took a sip of tea, "The case of Qian Meiyun jumping from a building, the deceased Qian Meiyun, female, 16 years old, a senior high school student, a dormitory student, excellent in character and learning, and a study committee member. The basic information is as follows. The following groups will report the visits one time.

Yang Jiaming looked up at everyone and signaled to speak first, "Man Li and I asked a few of Qian Meiyun's classmates and roommates about the situation, and the information we learned is as follows:

People who are close to Qian Meiyun, Luna, Qian Meiyun's roommate and deskmate, and monitor Sun Kai, have repeatedly mentioned in their statements that Qian Meiyun cares about her academic performance.

Qian Meiyun's parents are civil servants and have high demands on her studies. Luna said that Qian Meiyun's grades have regressed, her mother scolded her, and Qian Meiyun cried after returning to school.

Class leader Sun Kai also said that the class teacher puts a lot of pressure on the students' studies. Students who fail in grades will be criticized and educated, and even their parents will be invited.

Qian Meiyun's study pressure is still very high, because she was a very good student at first, because after entering high school, English became her weak point, so after a big exam exposed her weakness, she was very nervous.

Later, her grades improved and improved, but her classmates didn't feel her happiness. Sun Kai said that he thought Qian Meiyun was unhappy, but Qian Meiyun said it was nothing.

It’s summer vacation, and everyone went home separately. During the holiday, Qian Meiyun didn’t invite her friend Luna out to play. Some people rumored that Luna was dating friends, but Sun Kai said that Qian Meiyun was focused on studying and would not have a boyfriend. Meiyun also said that she didn't feel it.

The general feeling of students towards teachers is that Mr. Qin, the teacher in charge of the class, is very aggressive, but he is sincere to the students and hopes that they will get good grades.

My impression of other teachers is that they are very serious and responsible in class, but the teacher in charge of the class does not have evening self-study, and there is not much contact with them other than the usual class.That's all for now. "

Da Jing sat up, "Okay, let me report on my visit to Qian Meiyun's house with Nan Nan.

Qian Meiyun's family conditions are very good. Her parents are both civil servants with high education and stable jobs. Her mother was very emotional at first, but she eased up a little when we took the statement.

She said that there was no quarrel with Qian Meiyun before the incident. They both went to work. Qian Meiyun would read books and do homework at home during the holidays. It was the day when I went to make up classes, but something happened unexpectedly.

Qian Meiyun's father has never talked much, he is busy with work, and his mother Qian Meiyun's mother is in charge of his studies. He just asks about the test results. Since he is a girl, most of the heart-to-heart talks are carried out by his mother.

His father was very surprised that Qian Meiyun jumped off the building, because he felt that her grades had improved and there were no quarrels at home, so he really couldn't figure it out, why she couldn't think about it.

Qian Meiyun's mother said that she didn't find out that Qian Meiyun had a boyfriend or close friends of the opposite sex. Qian Meiyun is more homely and doesn't talk much at ordinary times. She basically studies and reads at home when she has nothing to do.nothing special. "

Guo Nannan took out a notebook, "This is a diary I found in Qian Meiyun's room. I went back and studied it carefully last night. This diary has been tampered with, because it is not a continuous diary, so the middle was drawn If you read the pages carefully, you will not find them. I counted the number of pages and inferred them based on the content before and after.

I suspect that the deceased recorded some important clues and was destroyed, but in order to avoid suspicion, he did not destroy the entire diary, just to guide us to investigate in other directions.

The content of the diary left in this book is basically about studying. She began to find that studying was getting more and more difficult and the pressure was getting heavier. It also recorded her mother's insults, and her father even beat her.

I checked the notes with Qian Meiyun's homework notes. It was my own handwriting. I can basically confirm that Qian Meiyun's father has a slight tendency to violence and beat Qian Meiyun many times because of her poor academic performance.

In a recent diary, Qian Meiyun said that studying is tiring and life is tiring. She is very confused. She doesn't know why she is studying, and she doesn't know if all the sacrifices are meaningful.You can feel the helplessness and confusion of a student between the lines.

It is worth noting that Qian Meiyun said that she likes a song by BTS, which is the motivation to support her to persevere.I went back and listened to it carefully. This is a Korean boy group. They are all passionate and inspirational teenagers born in the [-]s. The song mentioned in the diary is one of their main songs. The theme of the lyrics is to fight against the dark world.

Qian Meiyun mentioned many times that she likes this song very much. I personally think that she must rely on this idea to get through the difficult days, but this runs counter to the way she chose to commit suicide.

If she had to fight against the dark world in accordance with the spirit of the song she believed in, why did she choose to commit suicide?I didn't think about it all night last night. "

Chen Guojun looked at Su Yuyan, "Yuyan, please report the statement of the teacher we visited."

"En." Su Yuyan nodded, "Zhengyang High School is a key high school, and the enrollment rate is a very important indicator. For teachers, especially class teachers, the pressure is still quite high, so teachers are very concerned about students' grades. We find I got to know Qian Meiyun's head teacher, several teachers, and dormitory supervisors about the situation.

It was unanimously reflected that Qian Meiyun is a well-behaved student who studies hard. She doesn't talk much at ordinary times, and she is very down-to-earth. She is good at her homework except English. Later, with the help of English teacher Mr. Cao, her English scores improved through tutoring. Top five in class.

Teacher Cao also provided us with the recording of Qian Meiyun's father beating Qian Meiyun. After the appraisal department's appraisal, the recording was authentic and had not been processed or edited.

The dormitory administrator told us that the management of the female dormitory is very strict, no men are allowed to enter, the door is closed at [-] o'clock in the evening, and the dormitory is checked every night, and students who are not there will be reported and criticized. She does not know Qian Meiyun. After looking at the photo, she recognized the face and knew it was a student in the building, but she didn't know the name. She checked the records and found that Qian Meiyun had no record of staying out at night.

When looking at the records, we accidentally discovered that Qian Meiyun's roommate, Luna, had many times of returning late and staying out at night.The dorm manager knew Luna and said she looked pretty good, but she often didn't come back on time, but she didn't see the boy taking her downstairs, and they all came back by themselves.This is the case with our group. "

"Okay, technical team, Ding Ran, how is your school surveillance going?"

Ding Ran clicked the mouse and pushed his glasses, with a typical tech-savvy feeling, "I adjusted all the surveillance in the school and near the school gate, and I found a few things.

First of all, Qian Meiyun is a very regular person.She goes to school on time every day for self-study. I checked the time specially, and the error will not exceed a few minutes. She usually seldom goes out, and she is basically active in school. She comes on Monday and goes home on Friday.

Since the first semester of high school, she has taken part in tutoring, so her itinerary has changed. Every Monday and Thursday evening, she will go to classroom 501 to study English. The tutor is her English teacher Cao Jianyu. Each tutoring time is about 40 minutes. .

But I have a discovery, since Qian Meiyun started tutoring, Qian Meiyun has increased the time to go out, every Tuesday or Wednesday at noon, she will go out for two hours, I checked the video surveillance outside, she every time If you go out on foot, and then walk to a corner, you can't find anyone, and it's the same when you come back.

I suspect that she entered the sight of the campus in a monitoring blind spot. What is she doing when she goes out for two hours at noon every week? If she is shopping, she should choose the bus or subway, but I checked the surveillance at the bus station and the subway station, there is no Find her picture.

Through monitoring, I also discovered that Sun Kai and Qian Meiyun have an unusual relationship. Sun Kai is the monitor of their class. It stands to reason that it is normal for two people to contact each other, but I found that some of their personal behaviors are very intimate. "

Ding Ran enlarged the screenshot of the computer on the projector, and the screen showed that when there was no one around, Sun Kai was thirsty, so he picked up Qian Meiyun's cup and drank water, very naturally.

Ding Ran took a screenshot again, Qian Meiyun fainted from heatstroke in physical education class, and it was also the infirmary where Sun Kai carried her to the infirmary.Another picture was drawn, Qian Meiyun was wearing a hairpin, and in the next picture, Sun Kai bought this hairpin at the boutique in front of the school.

"Everyone has seen it, and I believe it doesn't take me much to know the relationship between Sun Kai and Qian Meiyun. They are having a secret love affair without telling everyone. These small pictures are relatively easy to find in the last semester, but the strange thing is that in the next semester It’s less.” Ding Ran took a few more screenshots.

At the end of the picture display, Chen Guojun sat upright, "Okay, let's talk about your thoughts based on the information you have so far."

Manli was thoughtful, "I just saw those screenshots, and I found a phenomenon. When Qian Meiyun met Sun Kai last semester, he was sweet and happy, but not only did the frequency decrease in the next semester, but every time Depressed and dull.

This is very contradictory to the information we have. It stands to reason that her grades could not keep up last semester, so she should be very anxious. When her grades finally catch up in the next semester, she should relax. But on the contrary, I always feel that since Qian Meiyun left After the semester began to make up classes, some changes have taken place, and the whole appearance is different.

And how to explain that she went out at noon, what did she do?Who are you seeing?Does Sun Kai know?Does Luna know?

There is no doubt that Qian Meiyun's father has a tendency to abuse. Whether it is a diary or a recording, it is already sufficient. Is that enough to prove that Qian Meiyun is likely to have a estrangement from her parents, and she has the idea of ​​committing suicide?

Another point is that Qian Meiyun is not the only student participating in tutoring, but there are not many students who have made great progress. Everyone knows that English is a basic course, and it is very difficult to make great progress in a short period of time. Although Qian Meiyun Yun is a student with good grades, but it is not easy to improve his English grade from 80 to over 110 in one semester. "
