Although Lao Zhang didn't understand psychology, based on years of experience in handling cases, he knew that when a person suddenly became angry, there was always something to hide.
He asked Gu You: "Miss Gu, don't you know this kind of hypnosis method? Why didn't you tell me in the bureau?"
Gu You smiled: "I don't know that in detail, and I haven't actually used it. I thought the old plan would tell you, I don't know how he got angry. It's weird."
"Then is this hypnosis method popular?"
"It's not popular. So far, I only know that the old plan will be used."
Lao Zhang and his partner exchanged a few opinions, and their conversation revealed their doubts about Ji Changxin and that they would come to him again.
In the evening, Lin Dongxue and Xu Xiaodong, who had found nothing, were eating a boxed lunch in the car. Chen Shi actually sent a photo at this time to show off his cooking tonight. Xu Xiaodong said: "The phone is here, watching the meal."
"You can take it and see for yourself!"
At the entrance of the subway station, a guy with yellow hair was playing the guitar, and passers-by stopped from time to time to throw a dollar into his guitar case.
Xu Xiaodong said: "I really envy freelance. I can go to work whenever I want to work every day."
"Maybe people still envy someone with a stable career... By the way, this person is singing at the entrance of the subway station every day. Will he see anything?"
"What can you see? Asked all afternoon today, mentioning May 7th, all you can think of is the matter of crushing people to death."
"Let's try your luck, isn't it just to try your luck in investigating a case!"
Lin Dongxue pushed the door and got out of the car. Instead of going up for questioning, she bought a bottle of mineral water and handed over the water and the police officer's card. Huang Mao froze for a moment and said, "Beautiful police officer, what's wrong with me?"
"Are you singing here every day?"
"It's not just in this place. There are several subway stations nearby." He took the mineral water and unscrewed a sip. "Thank you. I didn't expect the police to be so humane. It's much better than those city management who rushed me every day. Up."
"I want to ask you, have you seen this girl on May 7." Lin Dongxue showed the photo on the phone.
Huang Mao recognized it for a while and said, "I often see this kind of school uniform, but this girl is mediocre. How could I remember... Sorry!"
Lin Dongxue was disappointed and was about to leave. Huang Mao said, "But on May 7, there is another thing."
"I know, needless to say." Lin Dongxue has listened to it hundreds of times today.
"What? You know I caught a tram. Wolf?"
"What tram. Wolf!?"
"Haha, you still don't know, if you want to buy me an oden, I'll tell you."
Lin Dongxue didn't want to waste this money. The police's salary was only more than 4,000 a month, and she was still detained with bonuses recently, so she said, "Don't talk about getting it down, it should have nothing to do with the case I investigated."
"Hey, beauty, listen to me! I don't want to eat oden, can I?" Huang Mao stopped her.
Xu Xiaodong thought this guy was harassing Lin Dongxue, and said, "What are you doing?"
"This is also a policeman?" Huang Mao said.
"You can quickly talk about the tram. Wolf thing." Lin Dongxue urged.
Huang Mao eloquently talked about the deeds of his bravely arresting tramcar. Lin Dongxue thought that this would not be able to fight the case. It really was a waste of time.
At this time, Huang Mao said: "That guy, wearing a suit and tie, looks like a dog, and he did such a dirty thing. What a beast in clothes!"
"It doesn't seem to help us much, thank you." Lin Dongxue said.
"I'm sorry... By the way, is there a bonus for being brave?" Huang Mao said.
"Next time you encounter something like this, you'd better collect evidence and report to the police. Don't use violence. How old is the other party and you kick him. If you kick him, you will be responsible, and you will go to jail for yourself. Isn't that a tragedy?"
"It looks like it's just over 50 years old!"
"Don't be so impulsive next time."
"Okay, I get it."
Lin Dongxue turned and left. The two returned to the car and were about to go back first. When Xu Xiaodong started the car, Lin Dongxue remembered one thing and was going to check it with her mobile phone. The webpage she had previously checked was still there, and it was displayed on it. Ji Changxin’s molestation of young girls a few years ago.
Seeing Ji Changxin in a suit and leather shoes in the photo, Lin Dongxue suddenly had an inspiration, and she pushed the car door and jumped down. Xu Xiaodong was shocked and said, "Hey, are you crazy!?"
Lin Dongxue ran up to Huang Mao, raised her cell phone and asked, "Is that him? Tram idiot?"
Huang Mao looked at it for a while and said, "Hey, it's him. It turns out that this person has a prior history, but it turns out that he is still a psychologist!"
Lin Dongxue’s momentary sense of pleasure is just like the sudden passage of a cold nose that has been blocked for several days. Ji Changxin is a senior psychologist who understands hypnotism. He appeared on this section of the subway and there was a suspected hypnotic murder. Event, all of this is likely to be related.
Lin Dongxue asked Huang Mao to recall the clothes that Ji Changxin had that day. After Huang Mao finished speaking, he emphasized one detail: "When he got out of the car, someone tore his suit, and a large part of it was exposed from the back."
"thanks!"
At the case discussion meeting in the morning the next day, Lin Dongxue told his findings, and Lao Zhang also talked about what he saw Ji Changxin yesterday. When he heard this physiological hypnosis method, Lin Dongxue suddenly said: "Everything in the school The security guard who doesn't remember, there is a trace of acupressure on his neck."
Everyone talked a lot, but they didn't expect the clues to be rounded up here, which led to Ji Changxin's suspicion.
Lin Qiupu asked: "Captain Peng, what's the result of the autopsy?"
Peng Sijue shook his head, "The body has been taken away by the parents for cremation. I only got an autopsy record from the Medical University."
"Feeling is better than nothing!" Lin Qiupu said, "Now that you know that Ji Changxin will use this physiological hypnosis method, you can look for signs of acupressure on the autopsy record. Has the school's surveillance video recovered?"
The comrade of the Information Department replied: "The person who deleted the video does not seem to understand computers well and has recovered."
Lin Qiupu nodded, "I look for videos of schools and subways. Are there any figures of Ji Changxin appearing."
The follow-up video survey results are exciting. On the day the student committed suicide, a middle-aged man who was suspected of Ji Changxin had entered the school. Ji Changxin was also photographed during the surveillance of the subway station.
In the autopsy report, in a flashing shot, there was indeed an inconspicuous finger indentation on the corpse’s neck, which was exactly on the carotid artery.
According to Lin Dongxue's speculation, Fan Lizhong met Ji Changxin at the subway station on May 7. The two did not know what had happened. Ji Changxin decided to use his professional knowledge to clean up the bullying classmates for Fan Lizhong.
