The first deceased, Yan Qilin, was a senior high school graduate at the time. She was shy and introverted. She usually only liked reading books by herself. After the murder occurred, the police investigated three people.
The first one was Xiao Ran, a classmate and best friend of the deceased. The two had met each other since they met during the military training in high school, and they have been inseparable. Xiao Ran found a diary while sorting out the remains of the deceased. She took the initiative to hand it to the police. It mentioned that the deceased and Xiao Ran liked a boy at the same time, but then Xiao Ran took the initiative to withdraw. For this reason, the deceased often felt that Xiao Ran was owed. He treated her doubly.
Judging from the narrative in the diary of the deceased and Xiao Ran's own confession, it can be seen that the incident did not develop to the level of motives for the murder. Moreover, Xiao Ran has alibi evidence that she was dating another boy outside at the time of the incident.
The second one was Zhang Jinlei, the boy whom the deceased had a crush on, and was also a classmate. After graduation, the two people formally confirmed the relationship and reported the same university. It was the summer vacation of the third year of high school, so no one except Xiao Ran knew about their relationship. .
It may be that Yan Qilin's death hit Zhang Jinlei a great deal. He was very negative at one time, threatening to avenge Yan Qilin and fighting with a boy named Yue Chao, almost leaving the case.
At the time of the incident, the deceased was originally planning to meet Zhang Jinlei near Wuyi Road. He waited for a long time, but the phone could not be reached.
Although Zhang Jinlei was standing alone at the intersection and there was no alibi, but through various investigations, the police ruled out his suspicion.
The third was Yue Chao, who was also a classmate of the deceased, but for some reason he did not take the college entrance examination, so he dropped out in the second half of the third semester of high school.
Zhang Jinlei said that he had seen Yue Chao plot against the deceased, but Yue Chao said that he and the deceased had a brother-sister relationship. It was normal to fight and fight, because Zhang Jinlei was too sensitive and made a misunderstanding.
Where Yue Chao worked, the deceased often went there to play, and it seemed that the two had a good relationship.
Similarly, Yue Chao also had sufficient alibi, so the police also ruled out his suspicion.
After reading the thick confession record, Chen Shi said, "Where is the deceased's diary?"
"Keep it in the evidence room. I know what you are thinking. The diary is not forged. It is indeed the notes of the deceased. We checked the gutter and there is no trace of a page torn off. Zhang Jinlei has also seen it."
"How did Yue Chao drop out? A high school senior who dropped out must have made a big mistake."
"According to the teachers and classmates in the school, this student has always suffered from bad habits. The specific reason for dropping out is not very clear, but the police involved in the detection said that it had nothing to do with the deceased and was an independent incident."
Chen Shi stared at the fluorescent lamp in a daze.
Lin Dongxue said: "In fact, when the first homicide occurred, the three people, their classmates and teachers around the deceased did not know how many times they had been visited. The suspicion of acquaintances had been ruled out. After similar cases occurred, the police had determined that they were yes. A serial murder case."
"But, isn't there no progress in detecting serial homicides?... What about your brothers and the others?"
"out."
"A case?"
"No, the Lin team has already deployed police from various jurisdictions and police stations a few days ago. It has stepped up patrols this evening. Although it is a bit of a needle in a haystack, what if the running dog. Shit luck hits the murderer?"
Chen Shi smiled, "It seems that this case has tortured you hard enough."
"No, every year on the Qixi Festival, everyone's nerves are tightened... Do you think TA will commit crimes this year?"
"If there is a clear and clear law of crime, and there has been almost no show in six years, I think this murderer has formed a psychological stereotype, and he will definitely commit crimes this year."
Lin Dongxue sighed, "So helpless! I have to wait for the body of a girl to be sent here tomorrow."
"Hungry, go out to eat!"
Today, I was working on a case and didn't eat dinner, so the two went outside to order a bunch of barbecue. Chen Shi was eating while thinking, and he could see that his brain was working at full speed, and Lin Dongxue would not bother him.
Chen Shi suddenly said, "Think about it carefully, these cases are still different."
"What's the difference?"
"From the second case, the deceased were killed elsewhere and then left in a remote place. Only the first case was killed on the spot... Have you considered that the next five cases were all imitation crimes? "
"Think about it, but this case has not been made public. It is impossible for outsiders to know some details, especially the numbers written on the arm of the deceased."
"It's also..." Chen Shi picked up a lamb skewers depressed and ate it, his eyes were attracted by a flickering light that was gradually approaching, which was a police light on a police car.
Lin Dongxue also noticed that the police car returning to the bureau was still with the lights on. There must be something wrong. The two called the boss together in tacit understanding, then smiled at each other and said, "Check out! Pack!"
They hurried back to the bureau and saw a man being taken out of the police car. There was also a girl who seemed to be drunk watching her swaying.
The girl was drunk and crazy along the way, and said to Xu Xiaodong who was holding her: "Handsome man, how many phone calls do you have, why don't you talk?" Xu Xiaodong looked embarrassed.
Lin Dongxue asked Lin Qiupu: "What did this man commit?"
"I ran into it while patrolling, and he looked suspiciously."
The man shouted: "You are crazy, I am dating my girlfriend, why do you catch me?"
"Go in and talk about it!"
"A bunch of crazy people, I want to sue you."
Lin Dongxue looked familiar with the man, but she couldn't remember where she had seen it.
After knowing the man's name, she was so surprised that she could not close her mouth. He turned out to be Yue Chao, the person involved in the first murder case.
After six years, he is now twenty-five years old and works for a company that sells health products.
When the police were patrolling tonight, they passed the place where the first homicide happened that year. A community has already been built there. Yue Chao and the drunk girl were sneakily inside. When the police appeared, he pulled the girl out of his legs. Go, and then be stopped.
Then the police found a red dress and a bag of salt in the bag he was carrying.
Such reasons simply cannot make the police more suspicious of him.
The drunk girl was taken to the office to sober up, and Yue Chao was taken into the interrogation room. He appeared very impatient, shaking his legs and asking the police for cigarettes. It took ten minutes for Lin Qiupu to enter the interrogation room. Sitting opposite him, said: "After six years, let's meet again, tell me the reason for your arrest this time!"
Yue Chao curled his lips in disdain, "How do I know why you arrested me."
"What's the matter with this red skirt?"
"I bought it for your girlfriend!"
"Where is this packet of salt?"
"I bought it home to cook, is it illegal?"
Lin Qiupu sneered, "It is true that it is not against the law, but Yan Qilin was murdered six years ago, and a girl was killed in the same way every Chinese Valentine's Day every year. You are the person involved in the Yan Qilin case. You know what these two things mean together, you know better than me. !"
