Criminal Investigation Chronicle

In the early morning of September 9th, Zhao Lei took the initiative to invite Ying, and rushed to Langfang with Xiao Wang in the team. In Zhao Lei's view, what happened five years ago directly changed Zeng Qian's life, and also caused Lin Chong to start sleepwalking. The tragedy that happened yesterday , can't be dragged along with it, and it can't be explained by mere coincidence.The police academy, also organized by Li Liang, began to collect the fingerprints of the police academy personnel for comparison.

In the morning, Zhao Lei rushed to Langfang and came to Lin Chong's home.Lin Chong's mother is at home, and his father is at work.Seeing the two policemen, Lin's mother was a little surprised, and hurriedly asked, "Did something happen to Lin Chong at school?" "Don't worry, Lin Chong is fine at the police academy. A student was killed, and the victim happened to be from the same hometown as Lin Chong, and he studied in the same high school. We came here to learn about the victim’s situation. Why don’t we just drop by and see, Lin Chong asked us to say hello to you.” Zhao Lei explained road.

Zhao Lei: "Do you know Zeng Qian?"

Mother Lin: "Zeng Qian? I don't know." Mother Lin was a little confused.

Zhao Lei: "Then have you ever heard your son mention the name Zeng Qian?"

Mother Lin: "No, Lin Chong never mentioned this name."

Zhao Lei: "Let me know more about Lin Chong's sleepwalking. When did he start to sleepwalk, what did he do while sleepwalking, and how often did he sleepwalk?"

Mother Lin: "This child started sleepwalking not long after he was in his second year of high school. The first two times he got up and went out shortly after falling asleep. He walked to an alley and turned around a few times. The alley was not far from home. It was about one kilometer to the east when we went out. Later we locked the door of the house. He sleepwalked to the door and couldn’t open the door, so he wandered around the house a few times and went back to sleep. The frequency is not high. Sometimes it happens once every 20 days. Most of the time, it was sleepwalking for two consecutive days, and then I would not sleepwalk for a long time."

Zhao Lei: "Where is that alley, can you show me there?"

Lin's mother: "Just go out from our house and go east, about one kilometer, and two kilometers east to his old high school. I'll take you to see it." After speaking, he took the two of them there alley.

The alley is one kilometer east of Lin's house. The alley in those days has been expanded into a road, which has changed a lot, and there is not much information to be seen. The three of them turned back to Lin's house. "Then you are busy with your work, you don't need to worry about us." Zhao Lei said, after finishing speaking, Zhao Lei and Xiao Wang wandered around Lin Chong's house. Not long after, Zhao Lei's eyes stayed on a photo wall of Lin's house.The photos at that time also had a watermark of the year, month and day, and most of them were photos of a family of three. Judging from the date, it was indeed as Lin Chong said. In 93, Lin Chong was still a thin and short boy. By 94, Lin Chong had grown a lot taller. It is normal for adolescent children, especially boys, to grow more than ten centimeters a year.In Lin Chong's high school graduation photo, he has grown a lot taller, standing in the last row with a proud and confident smile on his face.

"Brother Zhao, take a look at this." Xiao Wang shouted to Zhao Lei who was fascinated by the photo wall.Xiao Wang is holding a very ordinary diary in his hand, the cover is not written, and the color is a little yellow.Zhao Lei flipped through it, and found that the content was very single. He wrote dozens of pages, nothing more than the unrequited love of an adolescent boy, until the last article: "September 1993, 9, I'm sorry, I'm a waste", the content is very short, the handwriting It is scribbled, and the content and font are quite different from what was written before, but if you look closely, it is still written by one person. "Well, the time was September 10, 93. The words Lin Chong revealed inferiority and self-blame, and at that time he was very confused and in a bad mood." Zhao Lei felt that it should not be far from his guess, But more evidence is needed, and on that piece of paper add: self-blame.

After bidding farewell to Lin's mother, they walked west along the Lin's house for two more intersections, and the two came to Zeng Qian's house.Both Zeng's parents were at home. Zhao Lei asked Zeng's father, "Do you remember the exact date when your daughter changed?" Qianqian, who was supposed to be home a long time ago, hasn't come back yet, when she came back, it was half an hour later than usual..."

"That's right, on September 9th, Zeng Qian returned late that night, and then stayed at home for more than ten days, and went to school again in late September, and Zeng Qian didn't know Lin Chong. In it, Lin Chong is unlikely to know the specific situation of Zeng Qian, but Lin Chong's diary was written on September 10, that is to say, before seeing Zeng Qian whose personality changed drastically, Lin Chong already knew what happened to Zeng Qian The matter, and what Lin Chong showed was more self-blame. The most important point was that when he was told that Zeng Qian's sex was torn, although he was almost emotionally broken, he did not show any surprise at all. So, that is to say..." Zhao Lei thought quickly, and what happened five years ago was basically clear.

After two o'clock in the afternoon, Zhao Lei and Xiao Wang returned to Yanjing. The police academy had collected a large number of fingerprints, and they were still comparing them, so there was no progress.Zhao Lei went to the police academy to find Lin Chong, "On September 1993, 9, after school that night, at the entrance of the alley where you sleepwalked, which is the small alley one kilometer east of your house, where you witnessed Qian was raped, but she didn't come forward, but chose to escape, pretending nothing happened, am I right?" Zhao Lei asked sharply.

"Yes, you are right. At 08:30 that night, we went home from study and school. Because it was very close to home, I walked home. Passing by that alley, I heard a voice coming from the alley. Zeng Qian's cry for help was not very loud, as if someone was covering her mouth, but she could hear it clearly. At that time, I was about to enter the alley, but there was a tall man at the entrance of the alley, holding a dagger against my neck , told me to get out immediately, and threatened me that otherwise I would kill me. I was very scared at the time, and wanted to save Zeng Qian, but there was nothing I could do. There were no street lights on the road, few pedestrians, and the moonlight was very dark. The alley was only a few tens of meters long, and it was a dead end. I hid at the entrance of the alley, lingering, not daring to enter, nor running, when I heard a conversation in the alley, 'Second, is there anyone outside', 'No, a fool , I didn’t see my face, don’t worry’, ‘It’s better to be careful, go and have a look, if there is someone, I’ll kill him...’ Hearing this, I ran away and ran all the way home, not daring to talk to my family. People said that they could not fall asleep repeatedly in bed. There should be at least two murderers that night. The man I saw was tall and tall. Hearing the conversation between the two, the voice of the questioner was deep and powerful. , the voice was rather shrill, I only heard the voices of these two people, not sure if there were any accomplices. Also since then, Zeng Qian didn’t go to school for more than ten days, and I also started sleepwalking a few days later, and during sleepwalking At that time, I ran to that alley and wandered around. It has been five years, and I have never mentioned this matter to anyone. I originally wanted to keep Zeng Qian a secret, but I didn't want to, but I didn't want Zeng Qian to be so pitiful that she was... "Lin Chong didn't beat around the bush, and said all these words in one breath, and exhaled deeply as if relieved of a heavy burden.

"Then do you think these two cases are related?" Zhao Lei asked.

"It's related, the time is too close, the release of the Buddha was done deliberately, the murderer was even more cruel this time, and after the sexual assault, he killed Zeng Qian. My intuition tells me that the two cases were committed by the same person. Moreover, choosing to commit the crime at the police academy is more like provoking the judicial system. He believes that the crime committed five years ago has been at large, but this time, perhaps by chance, he met Zeng Qian again, and Zeng Qian was still at the police academy. Studying, if he can commit crimes in the police academy and use worse and crueler methods to commit crimes, not only can he vent his desires, but also slap the judicial system on the bright side, and give him a sense of accomplishment. Officer Zhao, you What do you think?" Lin Chong asked back.

"Your analysis is very reasonable. I think no matter whether the two cases are committed by the same person or the same criminal group, at least the murderer this time is aware of Zeng Qian's misfortune." Zhao Lei said, indeed, there is a type of criminal After committing a crime, if they are not punished accordingly, they will continue to commit crimes, and even the methods of committing crimes will be more cruel and bad, and they will get pleasure from it.

Looking at the colleagues who set up fingerprint collection points not far away, Zhao Lei said, "Fingerprint comparison has not made much progress. Although the scope has been initially locked, there are thousands of students, teachers and other staff in this school. It’s the number one, if we can’t further narrow down the target, it may take a lot of time.”

"Well, I'll go to collect fingerprints first, and let me know if you have any news." Lin Chong also went to collect fingerprints.

Zhao Lei lit a cigarette, took two deep puffs, and kept thinking about the case in his mind. "Ah, Brother Zhao, there's something wrong with that boy who was talking to you just now!" The policeman responsible for collecting fingerprints shouted to Zhao Lei.Zhao Lei hurried over and asked, "What's the matter?" "Brother Zhao, although I haven't compared it carefully with the eyes, I can see that the kid's fingerprints are very close to the fingerprints extracted from the victims of the September [-]th case." , I'm very sensitive to fingerprints, so come and have a look." The young police officer in charge of collecting fingerprints was a little excited.

"How could this be?" Zhao Lei was very puzzled.
