"Silk."

"Is Le Zhiqiang? This person is not bad, there are more activities in the university, he often participates in it, and he can get rankings, whether it is in the middle of girls or boys, it is a pity that he disappeared, I hope he can come back as soon as possible. ”

"Do you know any enemies he has at school?"

"Enemies? There shouldn't be, if there is, I can't think of who it is, in my impression that no one will have an enmity with him, let alone that he is really good to people. ”

"Was there anything unusual when he left school that day?"

"Anomalous? Probably not, but he looked a little dazed that day, and we were going to play basketball, but he didn't go. ”

"In a trance?"

"yes, it looks like he's thinking about something, but when we asked him what was wrong, he didn't say anything."

"Do you know who he's in a dorm with?"

"You know, we're all divided into classes, so we're all in the same class, and I can take you to them if you need to."

"Okay, thanks."

"Silk Silk"

"Le Zhiqiang? Oh yes, he's been missing for a month and there's no news yet? ”

"Nope."

"No, didn't you call the police? I can't find anyone who has disappeared in these years, and I don't know what happened to him now. ”

"I want to ask him if there was anything strange about him before he came home that day?"

"Strange place? Absent-mindedness is true, I remember he was eating at noon and stuffing air into his mouth, and if we hadn't reminded him that he didn't know, it felt like he had something on his mind, but we asked him not to say. ”

"Did he see anyone that day?"

"I think about it, it seems that someone is looking for him, it was when we got out of class in the morning, I really wanted to go out for lunch, I saw that the person was a middle-aged man, Le Zhiqiang was normal before, but after the man came, his spirit became a little trance, as if the man told him something."

"Is that his father?"

"No, absolutely not, we've seen his father, so it's definitely not, and his father isn't bald, and the man looks very, well, how to put it, it feels mysterious, like that of a seasoned researcher."

"Researcher?"

"Yes, researcher, the man is still wearing a white coat, but he shouldn't be a doctor, he doesn't look like a doctor, and the doctor's words seem to be harmonious, but the person looks very uncomfortable. By the way, I asked him who it was, and he said he was asking for directions. ”

"Asking for directions?"

"Yes, he said he was asking for directions, but I don't feel that he was asking for directions, and after that, Le Zhiqiang's mood was not quite right, I and others asked him what was going on, but he didn't say."

"Did he contact you after that?"

"No, we usually come out to play with him on weekends, but this time I called him, and he didn't come out, just said that he had something to do."

"He didn't come to school on Sunday night, did he?"

"No, I haven't seen him since Friday, we don't know where he went, let's hope he's alive now, we haven't heard from him for a month, and everyone is worried about him."

"How was his relationship with his classmates at school?"

"Very good, he belongs to the kind of person who has good popularity, good study, and good sports, and generally no one will have an enmity with him, and I haven't found anyone to have an enmity with him."

"Okay, thanks, if you think of anything, please feel free to contact me."

"Silk Silk"

"Le Zhiqiang? I don't know him well. ”

"Aren't you classmates with him?"

"It's a classmate, but I'm not familiar with it, I usually play games, but Le Zhiqiang doesn't play games, so I'm not familiar with him."

"Don't play games?"

"That's right, he doesn't play games, there are only some ordinary functional software on his mobile phone, and there is no game software."

"It's rare."

"It's absolutely rare, and he doesn't play any of the games that are popular now, saying that he is worried about hurting his eyes, but he doesn't even play computer games."

"Isn't his popularity very good?"

"It's good, it's good, but those of us who don't play basketball are just ordinary classmates with him, and we don't have any other interactions except for studying."

"Did you notice anything strange about him before he left?"

"Because I don't know him well, I don't know, but when I was in class that afternoon, I found that he was playing with his mobile phone during class, although it is common in college, but it is not common in Le Zhiqiang's body at all, he usually listens carefully."

"Holding your phone all the time?"

"Yes, I kept looking at my phone, as if I was messaging someone, because I didn't know him well, I didn't ask him, you can ask his roommates, they should know more than me."

"Okay, thanks, if you have anything to think of, please contact me."

"Okay, goodbye."

"Silk Silk"

"Le Zhiqiang? Yes, he's my roommate. ”

"Was there anything strange about him before he left?"

"Yes, I guess it started at lunchtime, I was playing games in the dormitory at noon that day, so I didn't go to eat with him, they brought it back for me."

"You continue."

"After they came back and put it away, Le Zhiqiang sat on his bed and held something, because we knew that he didn't play games, so we were curious about what he was doing, so we leaned over to take a look and found that he seemed to be chatting with someone, but as soon as he found out that we were watching, he turned off his phone, so we didn't see who he was chatting with."

"Did the police show you the chat log in his hand?"

"I've seen it, but none of the avatars are right, the nicknames are not right, and none of them match."

"And after that?"

"We didn't have classes that afternoon, so he was going to go home, but before he left, he told us that we would use his things as we pleased, and we would buy them when he came back, but he only went home for two days, and we just thought he smoked, so we didn't pay attention to it."

"Let you use whatever you want?"

"Yes, let's use whatever we want, now that he thinks about it, he seems to know that he will be missing, and let's not be polite, he can eat whatever he wants."

"You haven't contacted him since?"

"I contacted him after his disappearance, but there was no response, we both had a good relationship, and now that he is gone, of course we will be anxious, we will look for him everywhere, everyone is contacting him, but there is no response."

"That's it, thank you for your cooperation, if you think of anything, please contact me in time."

"Okay, please be sure to find Le Zhiqiang."

"I'll do my best."

"Silk Silk"

"Le Zhiqiang? Are you the detective his mom was looking for? ”

"Yes, Mr. Zhao, please cooperate with my investigation."

"Okay, Le Zhiqiang's grades are good, and he participates in school activities very actively, we teachers like him very much, if this doesn't happen, he may be protected by us."

"It seems that you think highly of him."

"It's a fact, good students and teachers like it, and his papers also make me very satisfied, in the end, his disappearance is indeed a pity, a good child, it's a pity, hey."

"Okay, thank you for your cooperation, if you want any clues, please contact me, this is my business card."

"Well, okay, I'll leave this matter to you."

"Silk Silk"

"You're here because of Le Zhiqiang?"

"Yes, please tell me what kind of person Le Zhiqiang is in your cognition."

"He's a standout among everyone, good at studying, good at sports, good looking, there are a lot of girls who like him, but it's strange that he doesn't react to those girls."

"Oh?"

"Yes, we haven't seen him have a girlfriend, and we haven't seen him get close to any girls."

"Did you ask him?"

"I asked, he said that he wanted to wait until he graduated, and he probably had his plans, who knows."

"Thank you, for your cooperation, contact me if you think of anything."

"Okay, goodbye."

Information collation:

1. Before his disappearance, Le Zhiqiang was in a trance and had something on his mind

2. At noon on Friday, Le Zhiqiang saw a middle-aged man, bald, wearing a white coat, who looked like a researcher

3. Le Zhiqiang does not play any games, whether it is on the mobile phone or the computer, and his life is relatively monotonous.

5. Le Zhiqiang did not have any dating partners during his time at school.

Looking at the information he had recorded, he closed the notebook, and now it is certain that Le Zhiqiang had seen strangers before he disappeared, but he didn't know if Le Zhiqiang knew that person, and whether this person was related to the strange message that Le Zhiqiang's parents received.

Secondly, today's college students don't play mobile phones, and they don't even have mobile games, which is more strange, is it his habit or because of some other thing?

Who has Le Zhiqiang been messaging with, whether he knows or doesn't know, will the person receiving the text message be the man who talked to him at noon, and who tampered with the information in his mobile phone, if the information in his mobile phone has been tampered with, why didn't the police find out, isn't Le Zhiqiang's mobile phone the one in the hands of the police?

Le Zhiqiang's interpersonal relationship is good, it seems that there is no enmity in the school, students and teachers also have a high evaluation of him, and the surveillance watched by the police has also determined the time when Le Zhiqiang left the school, the last time he appeared was when he left the community where he lived, and then there was no trace, why did the person who called him know that the last place where Le Zhiqiang appeared was in the suburbs? What does he have to do with Le Zhiqiang's disappearance?
