Lu Siyu sighed. Song Wen stared at him more closely since he had a meal last night. He knew that he couldn't get through by fooling around, so he sorted out his thoughts and analyzed the background of several people.

“The Department of Civil Engineering had been popular for more than ten years ago, and now there are few girls as a choice. This major requires frequent worksites. There are a lot of dirty and tiring tasks. They also need to deal with migrant workers. These girls choose this. The reasons for professionalism are different. According to my inference, Dong Fang’s family may be related to real estate. The family hope her to study civil engineering and go back to inherit the mantle. Ma Aijing was born in an intellectual family, and her parents might have related majors. Guo Wei and Lin Wanwan’s family background is not very good. The Nancheng Civil Engineering Department has set up a large scholarship. This may be the reason why they chose this major."

Fu Linjiang listened carefully, and Song Wen nodded and moved his fingers to signal him to continue.

Lu Siyu continued: "Among the four, Dong Fang and Ma Aijing have a better relationship. Dong Fang feels that she is giving Ma Aijing a favor, but Ma Aijing doesn't seem to appreciate her. She is a little envious of Dong Fang's wealth. Also a little jealous."

These words made Fu Linjiang stunned, "How can you know this?" If he hadn't known that Lu Siyu had just arrived at the scene, he would have doubted that this kid had investigated behind them.

Lu Siyu did not answer. Instead, Song Wen opened his mouth to explain. While he was speaking, he stared at Lu Siyu, seeming to analyze his reasoning thinking: "The reason is quite simple. They have many things in the same style. Paper towels, slippers of the same type, and even sanitary napkins of the same type. Obviously, my girlfriends went to the supermarket to purchase them together."

Having said this, Song Wen pointed to the cosmetics of the two girls again: "Dong Fang likes to use high-end cosmetics. The cosmetics she buys are usually given away samples, but those samples appear in Ma Aijing's cosmetics, obviously Dong Fang It was given to her. Dong Fang's brand of lipstick is very famous. She has four of them here. Ma Aijing also put one on her table. I looked at Taobao before. This brand has a five-piece suit. Ma Aijing's color is very biased, so Dong Fang should think that the color is not suitable for her after buying it."

Fu Linjiang was so straightforward, he walked over and looked at the lipsticks: "I can't tell at all...what is the difference between the colors of these lipsticks."

"That lipstick is basically useless. Probably, even a beautiful woman can't control the death Barbie fan." Song Wen opened Ma Aijing's computer, and the QQ inside was set to automatically log in. "Ma Aijing is playing with There are some chat transcripts in which it is mentioned that she has a roommate who is rich and does whatever she wants. She is not as beautiful as her. In short, she admires Dong Fang while being her best friend, but is jealous of her and uses her."

After listening to Song Wen's analysis, Fu Linjiang suddenly started, and Lu Siyu nodded aside, acquiescing to these inferences.

Song Wen asked again: "What about others?"

"In the bedroom, Guo Wei is being isolated." Lu Siyu continued.

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

Song Wenyang read several data sheets in Yang's hand: "Probably because of this transcript, I have also noticed that when they were freshman, their electives were still normal, and several people overlapped with each other, but in the junior and senior years Fourth, Guo Wei’s elective courses perfectly evaded the courses taken by the other three, and chose a difficult and partial course. Generally, there are only so few elective courses to choose from. Most of the students in the same bedroom will choose to have a companion Going together can remind each other and inform each other, and Guo Wei’s chosen course is completely different from other people, presumably because he does not want to have other intersections with those students in the dormitory."

Hearing this, Fu Linjiang took the data sheet and looked at it. Song Wen had clicked it and he discovered that such an elective course sheet was indeed too abnormal.

"Also, eight months ago and half a month ago, there were records of two visits to the school infirmary in Guo Wei's case. They all had multiple bruises and some subcutaneous bleeding. She said it was caused by a fall. , I suspect it was beaten.” Song Wen pointed to Guo Wei's medical records while speaking.The school doctor prescribes some drugs to treat traumatic injuries. They may not fail to see the truth, but they are not too much.

These inferences sounded mysterious, but once they were explained, the reason was very simple, and Fu Linjiang quickly understood.

"Are there other discoveries?" Song Wen asked again.

This time Lu Siyu shook his head, and Junxiu's face returned to a frosty expression, I don't know if it's gone or he doesn't want to say any more.

These relationships are too superficial, he can see it, and Song Wen can also see it.However, the relationship between the four classmates in a dormitory can be far more complicated than what he saw.

Lu Siyu's gaze fell on Lin Wanwan's clean bed. It was clean, or even too clean. It was not at all like being carried away by an ambulance after a poisoning attack occurred after half asleep.Among the four people, Lin Wanwan was the most vulnerable person. He waited for the news that she woke up, and always had the opportunity to ask her.

Song Wen and Lu Siyu are two smart people, and there was a tacit understanding during the search. The answer, one said and the other, worked perfectly together, as if they could see through what the other party thought.

After listening to their analysis, Fu Linjiang took care of the portraits of several girls in his mind. He felt that he was not sleeping enough and his brain was not enough, and he sighed with emotion: "For four girls like this, it takes more than a dozen to chat on WeChat. Group it."

Lu Siyu corrected him expressionlessly: "Deputy team, only three or more people can build a group, so at most five groups."

At 3:30 in the morning, after the search was over, investigations and inquiries began. In order to save time, the police officers present were divided into two groups. Song Wen and Lu Siyu asked the policemen, and Fu Linjiang and the criminal police on duty who arrived first went with them. Talk to the head teacher.

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

Song Wen chose the thinner girl of the two to ask questions first. The girl was called Bai Xiaoxiao and she was as good as her name. She was not tall, had a small nose, small eyes, and a small face. Little glasses, the girl had not had time to change her clothes, she wore a white nightdress and a gown on the outside to cover her figure.The girl had a sense of cleanliness that she had never walked out of the campus and had no knowledge of world affairs. She sat in front of the two detectives, carefully picking at the dusty table with her nails.

This girl and Deng Jia in the same dormitory both studied communications engineering, and had different majors from the girls in Room 108.

Song Wenqing cleared his throat and started the routine. After asking his name and age, he cut to the subject. Bai Xiaoxiao didn't see much about the scene. After she and Deng Jia realized that the next door was the classmate outside, they hurried. Called the administrator.

After briefly describing the passage, Bai Xiaoxiao said in a low voice: "I knew that sooner or later something would happen to their bedroom."

Song Wen's heart moved, and he asked her: "Why do you say that. Are they at odds in the bedroom?"

"Well, to put it bluntly, you are bullying Guo Wei and isolating her." Bai Xiaoxiao whispered, looking up at the two young and handsome police officers in front of him, and mustered the courage to continue, "Guo Wei and I are fellow. They are all in the nearby Dong'an town. She studied very well with us. The town's unified exam was the third place. She fell to our school because of the question of filling in the volunteer. She is different from the others in their dormitory."

"Why is it different?" Seeing Bai Xiaoxiao hesitated, 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, other people won't know, right?"

Song Wen nodded: "That's for sure, our conversations here are confidential."

Bai Xiaoxiao grabbed the desktop again, and then continued: "I heard that Dong Fang's grades are not enough for our school. She came here after spending money at home, but I don’t have the proof for this. You can go by yourself. Cha, Ma Aijing, nicknamed the flatterer, would follow Dong Fang, play games every day, collect gifts from boys, and play a lot of secrets. These two people are bottom in every exam in their class."

The basic relationship is clear, and the situation is similar to what they inferred at the scene. Song Wen continued to ask her: "Can you tell me something specific? For example, what you know, how they bullied Guo Wei, and for example, they What is the contradiction between them, how did the relationship get to this step step by step."

Frozen three feet is definitely not a day's cold, how can a few girls have a deep hatred that must put each other to death?

Bai Xiaoxiao rationalized his thoughts and said, "As far as I know...There are a few things, the first one happened in the freshman year. We need to go outside to dry the clothes in the dormitory building. Each dormitory is allocated one. Clothes hangers, but there are so many people drying them, they are often messy, and throwing clothes or anything is common."

"Once I saw Dong Fang arguing with Guo Wei outside the bedroom, which meant that she lost a very expensive dress and believed Guo Wei stole it. Ma Aijing also helped and said, what a thief? The thieves were all scolded. Although Guo Wei was poor at home, but the people were very strong, she asked them to check and check, and she didn't find the clothes Dong Fang said, so Dong Fang changed his words and said that they were wrong. At this time, Guo Wei asked them to apologize, which is also a reasonable request, but Dong Fang is probably not up and down. He insisted that the facial cleanser and skin care products that he kept in the bathroom were often scarce. Guo Wei must have used it stealthily."

"There are proofs for clothes and cosmetics. It is unfounded. There was a quarrel on both sides, and there was no result, but Liangzi was settled. Later, the cosmetics in their dormitory were changed to the bedroom. Guo Hua didn't talk to them much anymore, who brought it in when they used it."

Song Wen nodded and let Bai Xiaoxiao continue.

"The second thing is that in the junior year, only Dong Fang had a laptop in their dormitory. You should also know that when you live in the dormitory, sometimes everyone picks up something and puts it temporarily. That day Dong Fangzheng Holding the notebook, the classmate next door suddenly called her something. She rushed out and put the notebook on Guo Wei's desk. Because Dong Fang's desks and chairs were always messy, and Guo Wei's desk was closest to the door. "

"Unexpectedly, when Dong Fang came back, he found that there was water on Guo Wei's desk and his notebook was wet. Later, he checked it and burned the motherboard. It cost more than 3,000 yuan to repair it. Dong Fang was at fault. You shouldn’t put things in random, but she insisted that the table was dry when she put it on. Guo Wei deliberately spilled water on the notebook in order to avenge her. Guo Wei said that the table belongs to her, and she found it on the table. After adding a laptop, she used to pour water, but she had never touched the computer, and she did not intentionally splash water to damage Dong Fang's laptop."

"This matter made a big deal. Both parties insisted on their own words. They quarreled the head teacher and even alarmed the dean of their branch. In the end, because Dong Fang's attitude was relatively tough, even his family came to put pressure on him. Guo Wei gave out five hundred meanings, and asked Dong Fang to promise to take good care of his valuables."

Song Wen frowned slightly when he heard this, and there was no camera in the bedroom. Who was telling the truth and who was telling the lie. There was no way to judge. The final way of handling it, it seemed, was to hit 50 each. board.Guo Wei felt wronged, and Dong Fang couldn't swallow this breath. They beat Guo Wei for the first time afterwards. That should be the first time Guo Wei went to the school hospital for medical treatment.

"Since then, they have been bullying Guo Wei, sometimes too much. Guo Wei often has to help them wash their clothes, wash their shoes, and wash the water in the bedroom. Once, I saw Guo Wei washing them. Lace underwear, crying while washing." said in a small voice.

Song Wen frowned. A girl being bullied like this is indeed very excessive.

"There is another thing that happened recently..." Bai Xiaoxiao lowered her head, "One day Guo Wei came to me for dinner. I saw a mark on her arm, she looked serious, she began to say She accidentally made it, and after I asked for a long time, she cried and said that Dong Fang was kicked..."

"We are about to graduate recently. Many students started looking for work units. That day, Guo Wei was waiting for an important interview call. If it went well, he could get an interview opportunity at the Planning Institute. There was a period of time when Guo Wei went out to open the water. The cell phone was placed on the bedroom table, and then the phone rang, and Dong Fang was sleeping, and he cursed there. Ma Aijing went to press the phone, and then mute Guo Wei's phone. Later, Guo Wei discovered I missed the call and made a call. Two hours later, the other party told her that the phone interview was over and that a suitable candidate had been found. Guo Wei was so angry that he was arguing with them, but was cursed and beaten by Dong Fang... …"

A lost piece of clothing, a broken laptop, and an unreceived phone call. Everything is not big when taken apart, but it is enough to make people depressed. The girls are incompatible with each other.

"Do the teachers in Guo Wei's class and other classmates know what they did about Guo Wei?" Lu Siyu asked softly.Hearing his sudden interruption, Song Wen turned his head to look at him. Under the light, Lu Siyu's skin was white as transparent, and his expression was extremely focused. His brows were slightly locked, waiting for the answer intently.

Bai Xiaoxiao blinked: "Naturally I don't know. This is a bit shameful. We are all college students and no children. How could we still sue the teacher. Even if there is a conflict in the bedroom, the teacher is at best. And thin mud. At first, Guo Wei didn’t even want to tell me, just because I was afraid of hurting me. I walked closer with Guo Wei, and they would bully me even if they were in different classes. Once I ate in the cafeteria, they deliberately The soup is splashing on me..."

Song Wen asked: "Then what do you say, you have known that something is going to happen in their dormitory? Is there a warning?"

Speaking of this topic, Bai Xiaoxiao's face changed slightly, and a hesitation flashed in his eyes. It seemed that after a psychological struggle, he opened his mouth: "Just after the phone incident, Guo Wei did not go back to the dormitory that day. Go to my place. I squeezed all night with me. At noon the next day, she...she told me that she didn’t want to live...I thought she was a little depressed at the time, and I still...I also enlightened her that it was not her that damn it, it was bullying her People... But, I was just to enlighten her to talk nonsense... I didn't expect... things would develop like this..."

Obviously, in Bai Xiaoxiao’s heart, it seems that it has been determined that the poisoning incident was that Guo Wei had poisoned in order to avenge Dong Fang and Ma Aijing. Speaking of this, Bai Xiaoxiao had tears in his eyes. As a fellow, She grew up listening to the name Guo Wei. She has always looked up to this girl. Later, they became classmates next door to a school, and they occasionally go home together during the holidays, which can be regarded as good friends.Now that things have developed to this point, Guo Wei has also been poisoned after such a big incident. She is a little worried, but more afraid.

Seeing that she was crying, Song Wen kindly handed over a tissue, and Bai Xiaoxiao thanked him, took it and wiped it, then she took the wet paper in her hand and twisted it, "Actually...Guo Wei had a chance to leave the dormitory. When she was a junior, a girl in our dormitory dropped out due to illness and had a bed. I once asked Guo Wei if she wanted to move over. Guo Wei was very happy at the time and said she Think about it, and apply with the teacher, but after half a month, I saw her again, but she said she would not move, and she was so happy at the time, I thought it was all right. But after a while, I saw her again Being bullied. This time too. I asked her if she wanted to move in a few days ago. She was obviously hesitating, but then she refused me."

"Why didn't she move out?" Song Wen asked. Looking at today's situation, Guo Wei still lives in 108.He didn't know whether the ending would be different if Guo Wei moved in at that time, or whether Guo Wei at that time had already made up his mind to stay in the dormitory and implement her plan?

"I don't know. This time, she took a few days off on May 1st, and then she suddenly said not to move over." Bai Xiaoxiao's voice became smaller and smaller, "I asked her what happened in the dormitory? Bullying her, she said it was all right, and let me not worry about it. I was also busy with my graduation thesis at the time, I didn't expect..."

Bai Xiaoshu stopped here for a while and asked, "Police officer, are they all right?"

Lu Siyu's recording pen paused and looked up at her. Due to the horror at the scene, the matter was of great importance. As reporters, they only saw Guo Wei and did not see Dong Fang and their bodies.The school and the criminal police who came before only told them about 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 coughed lightly and said to her: "The school should have a report on the follow-up situation."

"Where is Lin Wanwan?" Lu Siyu reminded her that there were four people in the bedroom next door.Song Wen didn't say anything from the side, as if he had a clear heart, and he was also about to inquire about Lin Wanwan's situation.

Bai Xiaoxiao recalled, "Lin Wanwan had good grades and a good person. Well, she looked like a little squirrel, but she looked round eyes, not tall, and petite. She is usually quiet, but she is very kind, and she has never blushed with everyone. But she is not very present outside, and she often goes out to work or something, sometimes not in the dormitory."

"Can you tell me something specific?"

"I don't know much about her, but I know that Guo Wei treats her very well and treats her as a friend. Once, Lin Wanwan came back from the outside and caught the heavy rain and was trapped in the bus stop outside. The rain was too heavy and everyone was too lazy to move. Guo Wei took the umbrella and picked her up. When the two of them came back, they were almost soaked. Normally, Guo Xu also helped Lin Wanwan with rice and so on. ."

In this way, Lin Wanwan was a very kind girl, and did not participate in Dong Fang and Ma Aijing's exclusion and violence against Guo Wei, and Guo Wei treated her very well.

"Do you know where Lin Wanwan works?"

"In the beginning, it was in a coffee shop around the school, and then I changed to a western restaurant. Then I didn't know where she was going. I only knew that she was going out several times a week."

"Do you know why she changed her part-time job?"

"It seems to mean that I am too close to the school and I always meet acquaintances, which is a bit embarrassing."

"Do they have a boyfriend?" Lu Siyu asked another question.

Bai Xiaoxiao hesitated and said, "I... I don’t go to class with them, and I don’t know much about other people. I just heard Guo Wei and other classmates say something. Ma Aijing has had several boyfriends, the last one She was dumped for three months. I haven’t heard of the following. Some people say that she seems to have a boyfriend, but no one knows who this mysterious boyfriend is. Maybe it doesn’t exist at all. Guo Wei has always been Single. I haven't heard that Lin Wanwan has a boyfriend, maybe I don't know. Now that graduation is approaching, everyone's mind is on thesis."
