Roommate Tong Ling muttered: "We didn't reject her, but we heard that she was pregnant with a child and committed suicide, and I think she is much more mature than us, and we can't talk about it at all." ”

Another roommate, Liu Jiashun, weakly explained: "I didn't say anything, I just felt ...... She's been through a lot of experience, and I don't really want to be friends with her. She's really, why don't she live with us if she doesn't live in other dormitories? ”

Hearing this, Jiang Tinglan couldn't wait to find a corner to hide.

She was originally an accounting student in the 89th grade, but because she was abducted, she didn't study for a year, and when she returned to school, she could only stay one level and enter the 90th grade. There are a total of five female students in the 89-level accounting major, and Jiang Tinglan used to share dormitories with other majors, and had a general relationship with the other four female students. After returning to school, the dormitory where I lived was already occupied, so I entered the dormitory for girls majoring in international trade in the 90th grade.

The class of 89 students have become unfamiliar because they haven't seen each other for a year, and the class of 90 students have just begun to know each other and are not familiar with each other.

——Hearing the discussion behind the back of her classmates, Jiang Tinglan felt a sense of "the world is big, but there is nowhere to stay".

The conversation in the dorm continues.

Wen Qianyu said unhappily: "Mature what? Jiang Tinglan is one year older than us, where is she mature? There are only three girls in our 90 international trade major, and there is just a bed vacated, she doesn't live here, where does she live? Besides, she has suffered so much, how pitiful. We are all girls, and we are at the same level and in the same dormitory, so we should understand and care more about her. ”

Hearing this, Jiang Tinglan was extremely grateful, and since then she and Wen Qianyu have been in and out together, forming a deep friendship.

Unexpectedly, when they entered the school in February, the two of them only got along for a semester, and Wen Qianyu was killed in October?

Zhao Xiangwan asked: "Are people still alive?" ”

There is more than one type of victimization, maybe the person is still alive, and I hope the person is still alive.

Jiang Tinglan couldn't control her emotions anymore, and cried on the phone: "No, no, the police have found her body." She's dead! She's dead......"

Zhao Xiangwan felt very uncomfortable.

Jiang Tinglan is introverted, and after experiencing the pain of being abducted, she talks less. Her true friend at Kyoto University of Economics and Business only heard Qianyu, why did she have an accident?

How did a twenty-year-old girl with flowers die?

Zhao Xiangwan sighed lightly: "Don't cry, talk to me slowly." How did Wen Qianyu die? What did the police say? Has the murderer been caught? ”

Jiang Tinglan said while crying, because of emotional instability, her words were a little upside down, but under Zhao Xiangwan's patient listening and inquiry, she slowly sorted out what happened.

Jiang Tinglan and Wen Qianyu studied very hard.

Jiang Tinglan was abducted to the mountains, and after experiencing domestic violence, pregnancy, suicide, and miscarriage, her body has not fully recovered, and her memory has decreased significantly. In addition, I haven't touched a book for a year, and a lot of professional basics have been forgotten. Even if she started to reread since her sophomore year, it was still a little difficult to pick it up, so she worked very hard, going to the study hall every day to study, and until she turned off the lights.

Wen Qianyu is a local, her parents both work in the petrochemical system, and the family conditions are good. She wants to study abroad, but her English score does not meet the requirements, so in addition to professional classes, she also needs to spend more time learning English, studying with Wen Qianyu every day, putting a Walkman in her pocket and a headset in her ear, and seizing all the time to practice listening.

Saturday, October 17, 1992, rain.

Jiang Tinglan and Wen Qianyu ate in the cafeteria together and returned to the dormitory to eat. After eating, the two went to study together in the study room on the first floor of the teaching building.

At nine o'clock, Jiang Tinglan felt a little cold, she wore a short-sleeved shirt when she went out, she didn't feel it at the time, but at night the cold came down a little unbearable. Jiang Tinglan raised her head and found that there were only two people left in the classroom, she and Wen Qianyu, so she proposed to go home.

Wen Qianyu still had a listening test that was not completed, so she asked Jiang Tinglan to go back first, and said that she would go home directly and not go back to the dormitory.

Wen Qianyu is from Kyoto, and occasionally goes home on weekends, Jiang Tinglan told her to pay attention to safety, and then took the umbrella back to the dormitory.

On Monday morning, Wen Qianyu hadn't returned to the dormitory, and Jiang Tinglan was a little anxious.

Tong Ling and Liu Jiashun, who were in the same bedroom, didn't care, they both said that they were such a big person, and Wen Qianyu was a local, what could happen? Most of them are sleeping at home and want to skip class.

On Monday morning, there were four classes in the accounting major, and Jiang Tinglan sat in the classroom uneasy.

Jiang Tinglan is particularly sensitive to these things because of her experience of being abducted. After finally four classes, Jiang Tinglan asked Wen Qianyu from the international trade class if she didn't come to class, hurriedly returned to the dormitory, found the phone book, went downstairs, and stood in the dormitory management office area on the first floor to call Wen Qianyu's home.

Wen Qianyu is an only daughter, the family conditions are very good, her father is the chief of the infrastructure department of the Kyoto Petrochemical General Plant, and her mother is a clerk in the financial department of the petrochemical plant. In 1990, Wen Qianyu lived in the dormitory after being admitted to university, and her parents spent a high initial installation fee to install a telephone in order to facilitate contact.

Jiang Tinglan knew Wen Qianyu's home phone, but it was only written in a palm-sized phone book, and she never dialed it.

The person who answered the phone was Wen Qianyu's mother Rao Xiang.

"Hey, hello."

Jiang Tinglan asked politely: "May I ask if it is Wen Qianyu's family?" ”

"Yes. You are? ”

"Hello Auntie, I am Wen Qianyu's roommate, my name is Jiang Tinglan."

Rao Xiang's voice was very gentle: "Ah, Jiang Tinglan, I know you, you are Qianqian's good friend." Is there anything wrong with you? ”

Jiang Tinglan asked, "Auntie, why didn't Wen Qianyu go back to school today?" There were four classes this morning, and she didn't show up. ”

Rao Xiang became nervous all of a sudden: "Isn't Qianqian at school?" Why didn't I go to class? ”

Jiang Tinglan was a little panicked: "I went home the night before yesterday, shouldn't she be at home now?" ”

Rao Qian also began to panic: "No, Qianqian didn't go home on Saturday, I called her at noon, and she said she wouldn't go home." ”

Jiang Tinglan's voice trembled a little: "The night before yesterday, I went to evening self-study with Wen Qianyu, and I left first at nine o'clock, and she said that she still had a little listening test and didn't finish it, and she would go home after about ten minutes." She often comes home on weekends, so she doesn't care. She didn't go back to the dorm on Saturday night, she didn't show up all day on Sunday, and she didn't come to class today, so I called to ask you. ”

Rao Qian sensed that something was wrong, hung up the phone and ran to school.

Jiang Tinglan hurriedly reported to the counselor, the school attached great importance to it, and after Rao Qian came over, she asked all her classmates and teachers, and they all said that they had not seen Wen Qianyu, and immediately called the police.

The Xishan District Public Security Bureau attached great importance to the disappearance of a female college student, and immediately filed a case and sent investigators into the school to conduct a visit and investigation.

Kyoto University of International Business and Economics is backed by Nishiyama and has an elegant environment, but it is far from the city center. If Wen Qianyu takes the bus home at nine o'clock in the evening, she should go out along the cement road in front of the main teaching building, go to the east gate along Xiangzhang Road, go out of the east gate, it is the bus stop, take the bus No. 25 or No. 510, get off at the petrochemical community station after ten stops, and walk for about five minutes to get home.

If Wen Qianyu leaves the classroom around 10:90, she should be able to get on the bus before 9:30 and get home at 10:00. This route is very familiar to Wen Qianyu, and the university campus is relatively simple, and no one feels that it will be dangerous.

The day of the disappearance was Saturday, and there were many entertainment activities for college students, such as a dance party in Jiawei Garden on campus, a basketball game on the lighted court, a movie in the small auditorium, and a row of restaurants, video halls, and karaoke halls on the street at the east gate. Even if it rains, it can't stop young people from playing.

Why is it that a big living person is gone?

Walking out of the teaching building at about 9:10, where did Wen Qianyu go? Do you go directly to the Dongmen bus station to take the bus, or do you go somewhere else temporarily?

From 21:00 on Saturday to 13:00 on Monday, 37 hours have passed since the disappearance, more than 6,000 teachers and students of Kyoto University of Economics and Business, covering an area of about 400,000 square meters.

The police took Wen Qianyu's photo and began to trace it line by line.

The first thing is to judge whether Wen Qianyu is out of the campus.

The east gate is a small open gate, which closes on time at eleven o'clock, and there is no security guard. The fruit vendor at the door said that there were a lot of people coming in and out on weekends, and they didn't pay attention to whether there were any Wen Qianyu.

The bus driver shook his head after looking at the photo, saying that there were many people getting on and off the bus at the University of Economics and Business station on weekend nights, and the driver and conductor couldn't remember whether there was such a girl at 9 o'clock in the evening.

The owners of the non-staple food shops, waiters and vendors in the small restaurants near the bus station, including the residents of the petrochemical community, asked all of them, and they all said that between nine and eleven o'clock, they did not see Wen Qianyu.

The line back to the petrochemical community by bus was broken.

This means that there is a wide range of searches to be made. From the campus to the bus station and the petrochemical community, accidents can happen everywhere along the way.

Wen Qianyu's parents are full of remorse, they usually trust their daughter very much, thinking that their daughter will go abroad in the future, and she has to exercise her independent ability, plus the girls' dormitory only has a phone on the first floor of the dormitory, if you want to find Wen Qianyu, you need to go to the fifth floor to find someone, so although there is a phone at home, the contact is not frequent.

Wen Qianyu's parents want to find their daughter, usually pick 12 noon, 6 p.m. to call, Wen Qianyu has told her mother at noon on Saturday not to go home, but I don't know why I suddenly got up at night to go home. By mistake, this is what happened.

The police were not discouraged and intended to start with the main school building and conduct a carpet search.

There are three teaching buildings in Kyoto University of International Business and Economics, one of which is a six-story building is the main teaching building, which is usually used at a high rate, and after two days, there is no trace of any trace in the classroom on the first floor where Wen Qianyu studied at night, and her schoolbag and umbrella are not there.

The self-study room on the first floor of the teaching building is open to the public at night, and the lights go out at 10 o'clock, and there is only a security guard in his thirties surnamed Feng on duty in the security room.

According to Feng Baoan, on the evening of the 17th, the Hong Kong film "Police Story" was shown in the small hall of the school, which attracted many students to watch it, and the self-study room was sparsely sparsely sitting, with only 20 or 30 people studying. It was raining a bit heavily outside, and he didn't pay much attention to the students' coming and going.

The police asked him if he had found anything unusual, and he first said that nothing was wrong, everything was fine, and he would go home from work as soon as the lights went out at 10 o'clock. Later, when I was in a hurry to ask about it, I said that when I went to the toilet at nine o'clock, I met a tall man standing in the toilet pool and didn't know what to do. Feng Baoan didn't look like a student, so he asked who you were, and the other party ran away in a panic.

When the police heard this, they felt uneasy and began to search the vicinity of the school building with their dogs.

Under the rest platform at the staircase, there is a tool room for cleaning utensils, the floor is about two meters high, usually only the cleaning staff stores mops, buckets and other sundries, open the door and find that there is a coat of Wen Qianyu, kneaded into a ball and stuffed between several mops, if it is not for the police dog nose spirit, it really can't be found.

Then, the dog went around the base of the wall and barked at a sewer.

The main school building is U-shaped, with a sewer in the recess on the north side. There are not many people here, and it is full of weeds and a bit desolate.

The police lifted the manhole cover and found Wen Qianyu's body in the sewer. The head is buried and stuffed into the sewer, the jacket is taken off, and only a small vest is worn, and there is sperm left in the body. There are bruises and purple marks on his body, and there are pinch marks on his neck, and he was beaten before his death.

The most terrifying thing is that after a forensic examination, it was found that Wen Qianyu died of drowning.

This means that she was still alive before she was stuffed into the sewers.

Speaking of this, Jiang Tinglan cried breathlessly: "Xiang Wan, Wen Qianyu was drowned by the stinky water of the sewer, she was drowned!" How scared she was then. If that security guard could check the utility room, he would find her and she would have been saved. Even if you are strong by that man. It's violent, as long as you live, there is hope, isn't it? But...... She was unconscious, and no one noticed her. I shouldn't have left early, I should have waited for her and sent her to the bus station before going back to the dorm. Our school was very lively that weekend, and there were a lot of people, but there were few people in the self-study room of the teaching building. ”

Zhao Xiangwan sighed again: "What did the police say? Is it certain that the man the security guard saw was the murderer? Could anyone have recognized the man? Is it a school employee, or a student? Did you find any footprints? Are there any criminal investigation portraits? ”

Jiang Tinglan cried and said: "Xiang Wan, I don't understand this, you are a criminal investigation professional, right, can you help?" Comrades from the Xishan District Public Security Bureau said that they had sorted out Wen Qianyu's social relations and carried out DNA testing, and they would work hard to catch the murderer. But...... Today is the third day, and there is still no result. ”

Zhao Xiangwan asked, "What can I do?" ”

Jiang Tinglan said: "Doesn't Ji Zhao know how to paint portraits? I'd like to ask him to help draw the guy the security guard saw. The Xishan District Public Security Bureau also said that the portrait was painted, but they were definitely not as good as Ji Zhao's painting. ”

Portrait? It seems that the police are also suspicious of the man who appeared in the toilet on the first floor at about nine o'clock.

However, it cannot be ruled out that teachers and students in the school committed crimes.

The panicked man may have just walked into the campus by accident and borrowed the toilet.

The entrance of Kyoto University of Economics and Business is guarded 24 hours a day, but the entrance and exit are arbitrary, and no one usually asks unless you encounter someone with suspicious behavior.

Zhao Xiangwan was silent and did not agree immediately.

Since the Xishan District Public Security Bureau said that it wanted to paint a portrait, it means that they have an exclusive criminal investigation portraitist in the bureau, and they and Ji Zhao went so rashly, I don't know if the other party welcomes it. Generally, the police have their own processes and methods for handling cases, and they are not willing to intervene or meddle with irrelevant personnel.

Jiang Tinglan knew that Zhao Xiangwan was a person with ideas, so she didn't say anything, and before hanging up the phone, she choked up and said: "Xiangwan, thank you for listening to me for so long, I can only hope that the police will catch the murderer early." ”

Zhao Xiangwan's heart was very heavy.

Safety management on university campuses has always been a problem.

Unlike the strict access control management of the Public Security University, many universities are open to the public, and the teaching area and family area are mixed, and people from outside the university can enter and leave at will.

The accident on a rainy night in the study room is completely a loophole in safety management.

There is only one security guard, who is in the security room in the foyer for a long time, and rarely patrols at ordinary times, and if something happens, the security guard doesn't know at all.

If it is a school teacher, a student or a family member, everyone cherishes their feathers and generally does not commit such a brutal homicide.

But what if it's an off-campus idler? Xingzhi walked around the campus, no one around, through the glass window, I saw a girl in her youth sitting in the brightly lit classroom, and she suddenly became evil, what should I do?

In homicide cases, the most difficult thing to track down is the murder of passion.

The other party and the victim don't know each other at all, and in a time that no one knows, they leave after killing someone, and they don't know it. Especially on rainy nights, when the rain washes away all traces and the body is hidden in the sewer for a while, what is the use of fingerprints, footprints, and DNA?

As long as the other party does not commit the crime again, there is no way to trace it.

You can't just pull a random person and ask for fingerprints, footprints, and DNA tests, right?

In the tragedy committed by Fan Hongwei, half a fingerprint was left at the scene, so what? Gu Wenjiao waited for ten years, but she couldn't find the real culprit. If it weren't for Zhao Xiangwan's whim to investigate Fan Hongwei, I am afraid that this matter would sink unjustly to the bottom of the sea until no one remembers it.

To be honest, after listening to Jiang Tinglan's words, Zhao Xiangwan was more inclined to this case as a murder of passion.

It cannot be ruled out that there are angry, jealous, and dissatisfied men in the social relations around Jiang Tinglan, but judging from the state of the scene, clothes were left in the utility room, the toilet cleaned the body, and the corpse was stuffed into the sewer...... None of them look like deliberate killings. The murderer was brutal, impulsive, and powerful, and the man Feng Baoan encountered, whether it was the time, body shape, or behavior, also conformed to this inference.
