Classmates ...... This gave Luo Chuan some new ideas. Although the two deceased may not have known each other and were not students of the first class, they were both from the same school. Due to the age span, the murderer has little chance of intersecting with both of them at the same time, so how did he choose the victim? Now it seems that it is very likely that it is through this classmate network.

Luo Chuan had a little idea in his heart, so he asked Xiao Yu again, are there any more eccentric students in the school that she has noticed? For example, they are withdrawn and unsociable, either silent or extreme, lack of empathy, indifferent and selfish, and so on.

Xiao Yu listened to Luo Chuan's description, and said with a wry smile: "What you said is a common person of our generation, right?" ”

"......" Luo Chuan was speechless for a while.

"University life was not as good as I imagined, and our shortcomings were exposed in a closed environment. I really can't help figure out who fits the most, because most people fit the most. In addition, I myself am the kind of withdrawn, silent, and unsociable person you mentioned, so I don't know much about them. I can only say that in school, there are many people like Zhao Ying, and there are many like me. Xiao Yu said lightly, there was no sadness or grievance, but the indifference and alienation in his tone made Luo Chuan feel distressed. It was an expression and tone that would only come after seeing the warmth and coldness of human feelings, and being extremely disappointed in human nature, really, really shouldn't have appeared on this girl.

Not wanting to put more pressure on Xiao Yu, Luo Chuan asked Xiao Yu about her life recently, and finally confirmed in a tactful way whether she had time to commit the crime. But it turns out that this is simply redundant, and Xiao Yu spends all her time in the research room and library except for classes, and those places have surveillance to prove for her that she is not a murderer.

After leaving the school, the first thing Luo Chuan said to Ke Xue was to ask Ke Xue to investigate the classmate network. If the killer screens the victim from a social networking site, it is much faster than going through the environment in person or going from house to house.

Ke Xue is also a good man in his hand, he doesn't need to return to the police force, he can use his mobile phone to complete the task assigned by Luo Chuan. So at this moment, he was in the co-pilot while holding his mobile phone to quickly check the network of his classmates, and at the same time said to Luo Chuan: "Team Luo, let me tell you, my awareness ability may be about to catch up with you!" From the moment I saw Xiao Yu, I felt that she was not a murderer. Now that Xiao Yu's suspicion has been ruled out, I have also got some clues from her. Although the two of us were different in age, we both came from this school, so it can't be a coincidence, right? Do you think the murderer is also a student at this school? Otherwise, why didn't he kill people from other schools, but from this school? If the murderer is also from this school, will there be room for him in this classmate's network? Oh, I'm so smart, I'm going to use my computer to show off my skills when I go back to the police force, and filter all the keywords they have posted on my classmates' network, so that I can find out who has those violent words in their logs, or who has the curiosity to eat people......"

Ke Xue was thinking excitedly, and Luo Chuan, who was driving, interrupted him impatiently and said, "Did you find that Li Li?" Did you know that you've used up all ten questions? ”

Ke Xue didn't dare to say more, and her slender and flexible fingers operated on the phone again, and then replied to Luo Chuan: "Found it, Team Luo!" Oops, it's the dead one! Ke Xue quickly looked at the information and information left by Li Li on the classmate's website, and then frowned and said, "Team Luo, this Li Li ...... She doesn't seem to be a good girl. She is exactly the same as Zhao Ying before, she is the kind of person who is arrogant and has a chaotic life, but she is four or five years older than Zhao Ying. If you have the information, it's easy to say, so I'll call our people to adjust the file. After speaking, Ke Xue began to call the relevant personnel within the police force to start investigating all the information about Li Li, and after confirming that it was correct, she could contact her family.

Luo Chuan drove the car, and his mind quickly turned all the characteristics of the two victims. It is not difficult to find out the characteristics of the murderer's search for a target. They all seem to be the kind of girls who are a bit like school bullies. In this way, the murderer should still be a student who has been bullied. But this Li Li has been graduating for so long, why do you want to kill her? What kind of hatred would have such a time span? Or is it ...... The psychological contact point of the murderer's murder is these school bullies? He observes these people through the online information of his classmates, sees who meets the standards, and starts to target whom. In this way, there is neither the old hatred nor the old hatred, nor will he be found through the relationship of the deceased, it is almost like a random choice, which is convenient for committing crimes.

However, if the murderer's goal is to kill those school bullies, then why are all girls chosen? School bullies, after all, there are still more men, and the ways and means of bullying are also stronger for men. Since the murderer is thoughtful and so ruthless, why does he have to kill only women?

Luo Chuan thought for a while, nodded himself, and the corners of his mouth hooked up with an imperceptible smile, he seemed to understand. This murderer is not "him", but "she". Xing Lao said that through the tooth marks left on the internal organs of the corpse, the murderer was either a very small man or a woman. Now it seems that the murderer should have been a woman. Because women's explosive power and enduring power are limited, it is not an easy task to subdue a man and torture and bite for a long time, gnawing and gnawing internal organs, the risk is too great, and the risk factor is very high. Because the murderer insists on eating the victim's internal organs, she cannot use poison to subdue the victim, and if the victim is poisoned, then she will also poison herself while eating people. So, she gave up her male goals and killed women.

Thinking of this, Luo Chuan immediately said to Ke Xue: "The murderer is in this classmate network, although I don't know her specific age, but she must be from this school." Find out the major events of this school over the years, as well as the major events that have happened to those students, and then cross-compare the people in the classmates' network to see if there are any comprehensive qualifications. Also, look at their cyberspace and photos to see if there are any people who are depressed, weird, and have anger and coldness in their eyes. Although what Xiao Yu said makes sense, most people are very cold and weird now, but they will never blame me to the extent that I said. ”

This time, Ke Xue didn't say much, nodded and immediately started to operate again. He used his mobile phone to compare the people in his classmates' network, and the police sent him all kinds of information he needed at the same time, Ke Xue quickly found what Luo Chuan wanted with his skilled operation and fast browsing ability.

"Team Luo, in the past ten years, there have been many major events in this school, but none of them seem to be useful to us. There was a jumping incident, and the reason seemed to be because of emotional frustration and I couldn't think about falling out of love. This has nothing to do with anyone, it should be possible to rule it out. There are also five incidents of serious injuries caused by fights, all of which were done by male classmates, so it shouldn't involve Li Li and Zhao Ying, right? There was also a student who dropped out of school because of a big change in his family. Although this should not be considered a major event, it is recorded in the major events of the student file. Ke Xue was a little puzzled and didn't understand why this situation was recorded in the big event.

Luo Chuan asked, "What is the reason for dropping out?" What is the big change? ”

Ke Xue scratched her head and said embarrassedly: "I don't know, it's strange here, I didn't write it clearly at all, I brought it in one sentence." But the school seemed to be concerned about this, but it didn't keep the student. ”

Luo Chuan nodded, and asked Ke Xue to cross-compare with the people in the classmate's network. It didn't take a while, Ke Xue grabbed the phone and shook it excitedly and said, "There you have it, Team Luo!" Cross-checked as you requested, and found a total of five people. One woman and four men. Respectively, because ......"

Without waiting for Ke Xue to finish speaking, Luo Chuan interrupted him and said, "Don't worry about the man for the time being, talk about the woman." ”

"Oh... Oh. Ke Xue didn't quite understand Luo Chuan's intentions, but she immediately read to Luo Chuan according to the things on her mobile phone: "This girl's name is Chen Xueru, twenty-three years old. She's the one who dropped out of school because of a change in her family, well... Yes, it happened last year. After that... Oh my God, after that, this girl was in a psychiatric hospital for half a month, as if it was psychological counseling. But because she was fine, she was discharged from the hospital again. After being discharged from the hospital, there was very little news, but she often wrote strange things on the Internet......"

"For example?" Luo Chuan interrupted Ke Xue again.

Ke Xue frowned, looked at her phone and said, "For example...... These two sentences she wrote after she was discharged from the hospital. Life is impermanent, human nature is ruthless, who knows who is crazy in the end? Some people look crazy, but in fact they just see through everything. Some people look like normal people and go crazy like animals... Ay? Team Luo, do you think this girl has deceived the mental hospital and has serious psychological problems? Most of what she wrote was dark and desperate. ”

"Are her parents gone? Can the police find out what happened to her? Luo Chuan was a little anxious, because he felt that he was already standing outside the door of the truth, very, very close.

Ke Xue said helplessly: "Team Luo, not all hackers in our police force." Even if they are hackers, some data records may not be stored in the computer. You'd better give us some time to get the information thorough. ”

"Well, I hope the murderer will give us time. You see, judging by the time between the murderer's outburst and successive crimes, how much time can she give us? If nothing else, maybe she's already stalking her target, waiting for an opportunity to strike. So if you don't hurry up, you'll soon have another piece of human offal on the table. Luo Chuan said, and suddenly added as if he remembered something: "By the way, you can continue to check now to see if there are any targets that meet the criteria for murderers." Those school bullies or girls who are usually not very good, it doesn't matter what age they are, as long as they are in this network. ”

Ke Xue understood Luo Chuan's intentions this time, if he could find the murderer's target in this way, then he could protect her earlier, or save her.

But in fact, as Xiao Yu said before, college campus life doesn't seem to be so good, at least this university is not so good. Ke Xue only checked for ten minutes and found eleven people who met the criteria. If it continues to be investigated like this, if it is a lawless world, the murderer may not be able to eat, so the difficulty of this investigation will undoubtedly increase.

returned to the police force, Luo Chuan asked Ke Xue to continue to investigate the information, and he came to the surveillance and analysis department with the photo of the girl named Chen Xueru, and called up all the surveillance of the two murder scenes. It wasn't until four o'clock in the morning that Luo Chuan finally made a major discovery, this girl named Chen Xueru had appeared at both murder scenes! In the surveillance of the shopping mall, Chen Xueru once wandered on the third and fourth floors with a peaked cap, and later there were photos of her onlookers in the small video recorded by the crowd at the scene. When Luo Chuan and the others went to the scene to investigate, Chen Xueru was outside the cordon, quietly watching them investigate the scene! And the surveillance at the main entrance of the hotel where Zhao Ying was killed also found the girl's entry and exit video. However, no record of her opening was found. If she doesn't live there, why did she go there?

In this way, the suspect seems to have been identified. Chen Xueru appeared twice, both wearing that peaked cap. Luo Chuan zoomed in on the hat from the video as clearly as he could, and found that there was a special gold embroidered logo on it. Maybe through this hat, you can find her more smoothly.

Luo Chuan almost never rested, and only in the morning did he barely close his eyes and lie down on the sofa in the office for a while. At more than nine o'clock in the morning, Ke Xue also brought good news. He found three most likely targets targeted by the killer, one of whom seemed to have not been home for two days.

Luo Chuan told Ke Xue about the discovery in the video, and then set off from the police force with a few police officers to find the potential victim.

Twenty-six years old, female, named Yang Xin. The "celebrity" of classmates on the Internet often takes pleasure in openly betting to rob other people's boyfriends, and is very popular on the Internet. She usually posts something on the Internet every day, but now she hasn't appeared for two days.

When Luo Chuan arrived at her house, her roommate said that she had sent a message today saying that she had gone to the train station, but did not say where she was going. Luo Chuan was anxious, the current situation must not allow Yang Xin to leave the city. It is very likely that Chen Xueru has already been with Yang Xin through some method, and if they go out of the city together, it will be even more difficult to save Yang Xin's life.
