As soon as he left the hospital, Xiao Zhao's phone called: "Team Jiang, we found a text message in the deceased's mobile phone and found an important clue. After Xiao Zhao hung up the phone, a WeChat message was sent to Jiang Chen's mobile phone, which was a photo. The person who sent the text message was Gu Yuan, and the text message content: Zhuo Yan, you don't have to die well, sooner or later, Lao Tzu will redeem the knife one day, and then use it to kill you. At this time, Forensic Doctor Li also uploaded the autopsy report on WeChat: the deceased is male, 38 years old, 188cm tall, weighs 80KG, the deceased was stabbed 17 times, 4 penetrating wounds all have serrated tear marks, 13 scratches, the fatal wound is a penetrating wound on the left chest (the first knife), but the wound shows traces of downward piercing, and no diazepam component was detected in the deceased's body. The deceased had no defence injuries on his body, and it was inferred that the penetrating wound to the left chest was the first knife, and the first knife penetrated the heart, and the deceased died on the spot.

The deceased is 188cm tall, and Wang Ling is only 155cm tall, In view of the height difference between the two, if Wang Ling wants to stab the deceased in the chest, there is a high probability that he will raise his hand and stab upward, so that the wound on the deceased's chest is likely to be stabbed obliquely upward, but the autopsy report said that the wound was stabbed obliquely downward, so Wang Ling's suspicion can be ruled out for the time being, and we decided to investigate this Gu Yuan first.

Jiang Chen and I came to Gu Yuan's house, and before we could press the doorbell, the door opened, and a middle-aged man with a large bag and a small bag looked at me and Jiang Chen with a panicked face. Jiang Chen said: "Gu Yuan, right, we are the Qingchuan City Criminal Police, and now there is a case that requires you to cooperate with the investigation" In the police station, after half an hour of surprise interrogation, Jiang Chen handed over the interrogation report to me.

Transcript of interrogation: Name of the party: Gu Yuan Gender: Male Age: 36 years old Background information: Gu Yuan had seen the victim on the night of the garment factory owner's case, and according to the content of the text messages on the victim's mobile phone, Gu Yuan had a conflict with the victim, and the content of the transcript is as follows:

Jiang Chen: Gu Yuan, tell me, why did you run just now?

Gu Yuan: I didn't kill anyone, I really didn't kill anyone.

Jiang Chen: We didn't say that you killed someone, didn't you confess to yourself, if you really didn't kill someone, just explain the matter clearly, what is going on?

Gu Yuan: Zhuo Yan and I have always been a partnership, he likes to collect knives, and my family has a limited collection of military stabbing daggers, Zhuo Yan he has coveted for a long time, some time ago I was not good at management and had financial problems, so I had to turn to Zhuo Yan for help, Zhuo Yan he asked me to use the dagger as a pawn, I had no choice but to give the knife to him, and later I learned that this was him in order to get my knife, so I found someone to cut off my goods and let me ask him for help.

Jiang Chen: What happened later?

Gu Yuan: After I found out, I called him and scolded him, and then he stopped answering my phone, so I texted him and told him that I would definitely redeem my knife, but he still didn't reply, so I went to his house, and after I went, I found that his door was not closed, but when I opened the door, I found out. He... He was dead, covered in blood, and the knife that killed him was my one, and I was terrified, and I was afraid that you would find me, and I really couldn't tell, so I took the knife and threw the other knife on the spot.

Jiang Chen motioned for Xiao Zhao to take someone to Gu Yuan's house to look for clues, and after a while, Xiao Zhao came back with a short knife. Xiao Zhao: "Captain, the luminol reaction was detected on the knife, the DNA is still being identified, one of the two groups of footprints at the scene belongs to Gu Yuan, and the other group has no clue yet." (Luminol reaction: The detection reagent reacts with iron ions in the blood and emits light, which can be used to identify blood stains that have been scrubbed from a long time ago.) ）

Jiang Chen said: "We have to go and see the surveillance again, I am looking for the stranger who entered the community before Gu Yuan after Wang Ling." "After some search and comparison, we found that there was a person who entered the community at 21:10 and left at 21:50, and we determined his physical characteristics according to the surveillance: height 180-185, weight unknown, thin body, dressed in white clothes, wearing a hat and mask, walking in a strange posture, and seemed to have a disability. Who is this stranger who appeared in the community at the time of the crime? It was already late after the record, and Jiang Chen and I temporarily closed the team.

Early the next morning, the criminal police officer in charge of investigating the deceased's social relations called and said that the deceased's life had been regular, and only that he had attended a high school reunion a week before his death. Jiang Chen and I immediately visited the people who were attending the class reunion at that time, and found that one of them could not be contacted, this person was named Lu Tao, and Lu Tao's right leg happened to be disabled! Jiang Chen and I went to the high school they were studying at the time and met their homeroom teacher at the time, Mr. Ma.

I said, "Hello Mr. Ma, we want to know more about Zhuo Yan, do you still have an impression that he was your student at the beginning?" ”

Mr. Ma recalled for a long time before he remembered and said, "I have an impression." ”

I asked again, "Then Lu Tao, do you still have an impression?" ”

Teacher Ma said: "Yes, Lu Tao's academic performance was among the best in the class at that time, but Zhuo Yan always bullied Lu Tao, Lu Tao slowly became no longer talkative, and his academic performance plummeted. We found the police records of that year in the old files of the police station, and the police records show that Lu Tao said that Zhuo Yan broke his leg, but because of the lack of evidence at the time, there was no result in the end.

Jiang Chen said: "Could it be because Zhuo Yan really broke Lu Tao's leg back then, Lu Tao always hated Zhuo Yan, and finally killed Zhuo Yan?" ”

I said, "Then why did Lu Tao choose to kill Zhuo Yan at this time?" ”

There must have been something at the class reunion a week ago that stimulated Lu Tao, and finally caused Lu Tao to lose control and kill Zhuo Yan, the group of lame footprints found at the scene of the crime, the lame person photographed by the surveillance is very likely to be Lu Tao! After we came out of the police station, we quickly rushed to the factory where Lu Tao worked, through the factory owner and Lu Tao's workers, we asked Lu Tao's address, Jiang Chen and I immediately led the team to Lu Tao's house in a bungalow, walked into this area and there was a smell, the garbage everywhere around, the ground was covered with domestic sewage, and after walking for a few minutes, we came to a most dilapidated house, Jiang Chen motioned to several police officers to surround the house, knocked on the door several times in a row and no one responded, Jiang Chen kicked the door open, And Lu Tao was hanging on the roof of the house. Lu Tao committed suicide with a suicide note on his desk...

Jiang Chen and I were silent after reading the letter, Xiao Zhao called someone from the trace examination department to come over, and searched Lu Tao's home and found the bloody clothes he was wearing when he committed the murder, and there was just a button missing from the clothes, the bloody palm prints on the wall of the murder scene and the bloody footprints on the ground also corresponded one by one, and the fingerprints on the murder weapon were also completely consistent with Lu Tao's, so the case was solved, but everyone was not happy. No one expected that the root cause of this tragedy would be the school bullying incident 20 years ago. The perpetrators of many years ago have become the victims of today, and the once cowardly and forbearant teenagers have become executioners who kill and vent their hatred, and the fate of the two people has been changed by the violence of youth and ignorance.

In recent years, news of school bullying has been common, with beatings, abuse, and isolation...... School life is supposed to be a simple and beautiful experience in life, but it becomes the beginning of a nightmare for those who are bullied. Physical wounds will always heal, but how to heal psychological wounds, those indelible mental devastation is the most terrible. In every case of school violence, the perpetrator is the initiator, but those who are indifferent bystanders are not contributing to the trouble? When it comes to avalanches, no snowflake is innocent! School bullying has not yet established relevant laws and regulations in our country, but this does not mean that bullies can act recklessly, which requires more people's efforts, in the face of this situation, please do not be indifferent, that is a silent support for violence, is acquiescence and connivance.

I hope that everyone who sees this story will take this as a warning, bravely say no to bullying, and stop being a silent victim and a silent majority.
