Criminal Investigation Notes

Lu Siyu sighs. Song Wen stares at him more closely since he rubbed a meal last night. He knows that he can't muddle through. Then he reorganizes his ideas and analyzes the background of several people.

"The Department of civil engineering was popular more than ten years ago. Now there are few girls to choose from. This major needs to go to the construction site frequently, there are a lot of dirty work, and they also need to deal with migrant workers from the contractor. The reasons why these girls choose this major are different. According to my inference, Dong Fang's family may have something to do with real estate. They hope that she can study civil engineering and go back to inherit her mantle. Ma Aijing was born into an intellectual family. Her parents may have been engaged in relevant majors. Guo fan and Lin wanwan are not in a good family. The Civil Engineering Department of Nancheng has set up a high scholarship, which may be the reason why they chose this major. "

Fu Linjiang listened carefully. Song Wen nodded and motioned his finger to continue.

Lu Siyu continued: "among the four people, Dong Fang and Ma Aijing have a better relationship. Dong Fang thinks that she is a benefactor to Ma Aijing, but Ma Aijing doesn't seem to appreciate it very much. She is a little envious of Dong Fang's money and a little jealous."

This said that Fu Linjiang was stunned, "how can you know these?" If he didn't know that Lu Si Yu had just arrived at the scene, he would have suspected that the boy had investigated on their back.

Lu Siyu didn't answer. Instead, Song Wen opened his mouth to explain. As he spoke, his eyes fixed on the landing Si Yu, as if to analyze his reasoning: "the reason is very simple. They have a lot of the same items, the same paper towel, the same slipper, and even the same sanitary napkin, which are obviously purchased by her friends in the supermarket."

After saying this, Song Wen also pointed to the cosmetics of the two girls: "Dong Fang likes to use high-end cosmetics. The cosmetics she bought are usually sent with small samples, but those small samples appear in Ma Aijing's cosmetics, which are obviously given to her by Dong Fang. Dong Fang's Lipstick Brand is very famous. She has four lipsticks here and one on Ma Aijing's desk. I've searched Taobao before. There are five suits in this brand. Ma Aijing's one is very partial in color, so Dong Fang thinks the color is not suitable for her after she bought it. "

Fu Linjiang showed his straight nature and went to look at the tubes of lipstick: "I can't see it at all What's the difference between the colors of these lipsticks

"That lipstick doesn't work. Maybe, even beauty can't control Barbie powder." Song Wen opened Ma Aijing's computer, QQ set automatic login, "Ma Aijing has some chat records in the game, mentioning that she has a roommate who can do whatever she wants with money. She is not as beautiful as she is. In short, she envies Dong Fang and is jealous of her and uses her at the same time."

After listening to the analysis of the Song Dynasty, Fu Linjiang just opened his mouth and Lu Si language nodded his head at the side, acquiescing in these inferential processes.

Song Wen asked, "what about others?"

"In the bedroom, Guo is isolated." Lu Si continued.

Fu Linjiang continued to be surprised: "I see that Guo Zhen has a gap with other girls in achievement and family, but not to the extent of being isolated? How do you see that? "

Song Wenyang raised several data sheets in his hand: "probably because of this score sheet, I also noticed that when I was a freshman, their elective courses were still normal, and several people overlapped with each other. However, when he was a junior and a senior, Guo's elective course perfectly dodged the courses taken by the other three and chose the difficult and partial courses. Generally, there are only a few elective courses to choose from. Most of the students in the same dorm will choose to go with a partner, which can remind each other and also send information. However, Guo Zhen's selected courses are completely different from others. I think he doesn't want to have any other intersection with the students in those dormitories. "

When Fu Linjiang heard this, he took over the data sheet and looked at it. Now that he was punctured by Song Wen, he found that such an elective course list was really abnormal.

"What's more, eight months ago, and half a month ago, Guo's case had two visits to the school's medical room. They were all bruises and some subcutaneous bleeding. She said it was caused by a fall. I suspect it was beaten." Song Wen said that he pointed to Guo's medical records. The school doctor prescribed some medicine for the treatment of injuries. They may not have seen the truth, but they have nothing to do.

These reasoning sounds abstruse, once explained, the truth is very simple, Fu Linjiang soon understand.

"Any other discoveries?" Song Wen asked again.

This time, Lu Si language shook his head, and Junxiu's face recovered his cold expression. I don't know if it's gone or I don't want to say it again.

These relations are too superficial, he can see, Song Wen can also see. However, a dormitory of four students, the relationship can be far more complex than what he saw.

Lu Si Yu's eyes fell on Lin wanwan's clean bed. It was clean, even too clean, and it was not like being carried away by an ambulance after a sudden poisoning attack after half a sleep. Among the four, Lin wanwan was the least poisoned. He waited for the news that she woke up and always had the opportunity to ask her.

Song Wen and Lu Si Yu were two wise men. They had some tacit understanding during the search. The conversation just now, one said and the other explained. They cooperated perfectly, as if they could see through each other's thoughts.After listening to their analysis, Fu Linjiang arranged the portraits of several girls in his head. He felt that he did not have enough sleep and his brain was not enough. He sighed with emotion: "for such four girls, it's necessary to attract more than ten groups to chat with wechat."

Lu Si corrected him expressionless: "deputy team, more than three people can build a group, so at most five groups."

At 3:30 in the morning, after finishing the search, they began to investigate and inquire. In order to save time, several policemen on the scene were divided into two groups. Song Wenyu and Lu Siyu asked the police. Fu Linjiang and the first criminal police on duty went to talk with their head teacher.

The so-called inquiry room was temporarily recruited in the dormitory building. There was a lot of dust in the room, and the corners were filled with sundries, including some disinfectant water and used chairs.

Song Wen chooses the thinner girl of the two to do the inquiry first. The girl is called Bai Xiaoxiao. She looks like her name. She is not tall. She has a small nose, small eyes and a small face plate. She has a pair of small glasses. Before she can change her clothes, she wears a white nightdress and a coat on the outside to cover her figure. The girl has a kind of clean feeling that she has never walked out of the campus and disdains the world. She squats in front of two criminal policemen and carefully picks the dusty table with her nails.

This girl and Deng Jia, who lives in the same dormitory, are both studying communication engineering. They are different from 108 girls in their major.

Song Wenqing opened her throat by asking her name and age. After asking about her name and age, Bai Xiaoxiao didn't see much about the scene. When she and Deng Jia saw clearly that the student was next door, they immediately called for the administrator.

After a brief description of the process, small white voice: "I know, sooner or later, their bedroom will have an accident."

Song Wen's heart moved and asked her, "why do you say that. Are they at loggerheads? "

"Well, to put it bluntly, I was bullying Guo fan and isolating her." Bai Xiaoxiao murmured, looked up at the two young and handsome police officers in front of her, and summoned up the courage to continue, "Guo Ji and I are fellow townsmen, both from Dongan town nearby. She studied very well in our school. The third place in the town's unified examination was that she fell into our school because of the problem of filling in the application form. She's not the same as the rest of their dormitories. "

"Why not?" Looking at Bai Xiaoxiao's silence, Song Wen asked again, and then he added, "this information is very helpful for us to find the murderer."

Bai Xiaoxiao still hesitated: "that What I told you, the rest of us won't know, will you

Song Wen nodded: "that's for sure. Our conversation here is confidential."

Bai Xiaoxiao pinched the table again, and then went on to say: "I heard that Dong Fang's grades are not enough for our school. Her family spent money to get here, but I don't have a certificate for this. You can check it by yourself. Ma Aijing's nickname is flatterer, and she will follow Dong Fang, playing games every day and accepting boy's gifts. There are so many backstage plays between these two people They are at the bottom of every exam in their class

The basic relationship is clear, similar to what they infer at the scene. Song Wen continues to ask her, "can you tell me something specific? For example, as you know, how they bullied Guo, and for example, what contradiction did they have between them and how their relationship got to this step by step. "

Rome wasn't built in a day. How can a few girls hate each other so much that they must kill each other?

Bai Xiaoli thought and said, "as far as I know There are several things. The first one happened in freshman year. We need to go outside to dry clothes in our dormitory building. Each dormitory is assigned with a clothes hanger, but there are a lot of people there to dry clothes. It's a common thing to lose clothes and so on. "

"Once I saw Dong Fang fighting with Guo Zhen outside my bedroom. It means that she lost a very expensive dress, and she believed that Guo Jian had stolen it. Ma Aijing also helped to say that she had scolded all the thieves. Although Guo Zhen's family was poor, she had to be strong. She asked them to check and check. They didn't find the clothes Dong Fang said. Dong Fang changed her mind and said that she was wrong. At this time, Guo Zhen asked them to apologize, which was also a reasonable request. However, Dong Fang probably couldn't get up and down. She insisted that the amount of facial cleanser and skin care products that she put in the bathroom was often small. Guo must have stolen it. "

"There are still vouchers for taking clothes and less cosmetics. It's a matter of no evidence and no evidence. The quarrel between the two sides is too much, and there is no result. But Liang Zi has come to an end. Later, the cosmetics in their dormitories were changed to be put in the dormitories. When anyone used them, Guo Zhen didn't talk to them very much

Song Wen nods and asks Bai Xiaoxiao to continue.

"The second thing is that when she was a junior, only Dong Fang had a laptop in their dormitory. You should also know that when you live in the dormitory, sometimes you will pick up something and put it temporarily. That day, Dong Fang was holding a notebook when a classmate next door suddenly called her something. She was in a hurry to go out and put the notebook on Guo's desk. Because Dong Fang's desks and chairs are always quite disordered, and Guo's desk is closest to the door. "

"Unexpectedly, when Dong Fang came back, he found that there was water on Guo's desk, and his notebook was wet. Later, he took it for inspection and burned the motherboard. It cost more than 3000 yuan to repair it. Dong Fang was wrong and shouldn't have put things around. But she insisted that the table was dry when she put it. It was Guo Zhen who intentionally spilled water on her notebook in order to revenge her. Guo Zhen said that the table was hers. After she found a notebook on the table, she used to pour water. However, she did not move the computer, nor did she intentionally splash water to damage Dong Fang's notebook. ""This matter is very big. The two sides hold their own opinions and quarrel with the head teacher, and even disturb the dean of their branch school. Finally, because Dong Fang's attitude is relatively tough, and even family members come to pressure, the teacher makes Guo Zhen give a 500 meaning and make Dong Fang promise to take good care of his valuable property."

Song Wen frowned a little when he heard this. There was no camera in the bedroom. It was impossible to judge who was telling the truth and who was lying. It seemed that the final way to deal with it was to play 50 pieces of each. Guo Zhen felt aggrieved and Dong Fang couldn't swallow it. After that, they beat Guo for the first time, which should be the time when Guo Zhen went to the hospital for the first time.

"Since then, they have been bullying Guo Zhen. Sometimes it is too much. Guo often has to help them wash their clothes, brush their shoes, and tap the water in the bedroom. Once, I saw Guo Zhen washing their lace underwear, crying while washing." Little whisper.

Song Wen frowned, a girl was so bullied, it is really too much.

"Another thing happened recently..." Bai Xiaoxiao lowered her head. "One day Guo Zhen came to eat with me. I saw a trace on her arm. It looked very serious. She began to say that it was caused by her carelessness. After I asked for a long time, she cried and said that she was kicked by Dong Fang..."

"We are near graduation recently. Many students began to look for work units. That day, Guo Zhen had been waiting for a very important interview call. If it went well, he could get an interview opportunity from the Planning Institute. For a period of time, Guo went out to turn on the water and put his mobile phone on the bedroom table. Later, the phone rang. Dong Fang was sleeping, and he scolded ma Ai Jing used to press the phone, and then turned Guo's phone to mute. Later, Guo found that she missed the call. It was two hours later, the other party told her that the telephone interview was over and that a suitable candidate had been found. Guo fan was so angry that he argued with them, but he was scolded and beaten by Dong Fang... "

A piece of lost clothes, a damaged laptop, a phone call not received, everything is not big, but it is enough to make people sad, these pieces of time superposition, finally let a few girls.

"Do the teachers and other students in Guo's class know about the things they beat Guo?" Lu Si asked softly. Hearing his sudden interruption, Song Wen turned to see him. Under the light, Lu Si Yu's skin was as white as transparent, and his expression was extremely focused. His brow was slightly locked, waiting for the answer.

Bai Xiaoxiao blinked: "of course, I don't know. It's a bit humiliating. We are all college students, and we are not children any more. How can we still sue the teacher. Even if there is a bit of dormitory conflict, the teacher is at most reconciled. At the beginning, even I didn't want to tell him, because he was afraid of implicating me. Guo Zhen and I are closer. Even if they are different classes, they will bully me. Once I was eating in the canteen, they deliberately spilled soup on me... "

Song Wen asked, "how do you say that you knew something was going to happen to their bedroom? What are the omens? "

Speaking of this topic, Bai Xiaoxiao's face changed slightly. There was a flicker of hesitation in her eyes. It seemed that after some psychological struggle, she opened her mouth: "just after the telephone incident, Guo Zhen didn't go back to my dormitory that day. She went to my place and crowded with me for a night. At noon the next day, she She told me she didn't want to live I thought she was a little depressed, and I was I also told her that it's not her who should be damned, it's the bully But I was trying to enlighten her I didn't expect Things will develop like this... "

Obviously, in Bai Xiaoxiao's heart, it seems that it has been recognized that the poisoning incident was poisoned by Guo Zhen in order to revenge Dong Fang and Ma Aijing. Speaking of this, Bai Xiaoxiao has tears in the corner of her eyes. As a fellow townsman, Guo Zhen's name was heard and grew up. She has always looked up to this girl. Later, she became a neighbor of the school, occasionally during the holidays Go home together, can be regarded as good friends. Now things have developed to this stage, such a big thing, Guo Zhen also poisoned, she is a little worried, more is afraid.

Seeing her cry, Song Wen kindly handed over a paper towel. Bai Xiaoxiao said thanks and wiped it. Then she took the wet paper in her hand and twisted it, "in fact Guo Fen had a chance to leave the dormitory. When she was a junior, a girl in our dorm left because of illness. She had an empty bed. I once asked Guo fan whether she wanted to move here. Guo was very happy at that time. She said that she would consider it and apply with the teacher. But half a month later, I saw her again, but she said she would not move. At that time, she was very happy, and I thought that she would It's OK. But after a while, she was bullied again. This time, too. A few days ago, I asked her if she wanted to move here. She was obviously hesitant, but later she refused me

"Why doesn't she move?" Song Wen asked, looking at today's situation, Guo Zhen still lives in 108. He did not know whether the outcome would have been different if Guo Zhen had moved here at that time, or whether Guo had made up his mind to stay in the dormitory and carry out her plan at that time?

"I don't know. This time, she took a few days off on May Day, and then suddenly said she would not move in." White small voice is getting smaller and smaller, "I asked her how the bedroom, is still bullying her, she said it's OK, but also let me not worry. I was also busy with my graduation thesis. I didn't expect that... "Bai Xiaoshu stopped here for a moment and asked, "officer, are they OK?"

Lu Siyu's pen was recorded. She looked up at her. Because of the terror at the scene, it was very important. As the informers, they only saw Guo Zhen, but not Dong Fang and their bodies. The school and the previous criminal police only told them the collective poisoning in the dormitory next door, but did not tell them the exact news. Now it seems that Bai Xiaoxiao does not know that Dong Fang and Ma Aijing have passed away.

Song Wen gently coughed and said to her, "the follow-up situation should be informed by the school."

"What about Lin Wan Wan?" Lu Si Yu reminds her that there are four people in the bedroom next door. Song Wen didn't say anything, as if he had a soul in his heart. He also wanted to ask about Lin wanwan.

Bai Xiaoxiao recalled, "Lin wanwan that person, the results are also very good, the person is also very good, well, she looks like a little squirrel, that is to say, her eyes are round, she is not tall, she is petite, she is usually quiet, but she is very kind, and everyone has never been red. But she is a person who doesn't have a sense of existence outside. She often goes out to work or something. Sometimes she is not in the dormitory

"Can you say something specific? "

" I don't know much about her, but I know Guo Zhen is very kind to her and regards her as a friend. Once, Lin wanwan came back from the outside, caught in the heavy rain, and was trapped in the bus stop outside. The rain was so heavy that everyone was too lazy to move. Guo Zhen took an umbrella to pick her up. When they came back, they were almost wet. At ordinary times, Guo fan also helps Lin wanwan to get rice and so on. "

In this way, Lin wanwan is a very kind girl, and has not participated in the ostracism and violence of Dong Fang and Ma Aijing against Guo Zhen, and Guo Jian is very kind to her.

"Do you know where Lin wanwan works?"

"At first, it was a coffee shop around the school. Then I changed to a western restaurant. Then I didn't know where she went. I only knew that she went out several times a week."

"Do you know why she changed jobs?"

"It seems to say that it's a bit embarrassing to be too close to school and always meet acquaintances."

"Do they have boyfriends?" Lu Si Yu asked another question.

Bai Xiaoxiao hesitated and said, "I I don't have classes with them. I'm not familiar with other people. I just heard from Guo Zhen and other students. Ma Aijing has had several boyfriends. The last one was dumped by her. It has been three months. The latter has not been heard. Some people say that she seems to have a boyfriend, but we all don't know who this mysterious boyfriend is. Maybe it doesn't exist at all. Guo Zhen has always been single. I haven't heard that Lin wanwan has a boyfriend. Maybe I don't know. Now, as graduation approaches, everyone's mind is on the thesis. "
