Guan Zheng sent Yang Chen away, and threw all the documents to Xu Jiuyan. Xu Jiuyan took it and said, "You are really magical, everyone knows you!"
"It's nothing. He had helped him break an arson case when he was in college, and he had only seen it a few times.
Xu Jiuyan waved her ingenuity once, and said: "It seems that you are not familiar with each other, and he is a major, with more than ten years of military service. You are quite different in age but you can be friends. He trusts your business very much."
Guan Zheng stopped and said: "Okay, there is progress, what's the conclusion?"
"You are very popular, you work hard, and it is easy to win people's hearts."
"Am I easy to win people's hearts?"
Xu Jiuyan nodded and said, "Yes, you are very good with anyone, even the grandfather and aunt of the cafeteria are very familiar with you."
"Then do you know why?"
"Because you are very good at handling cases!"
Guan Zheng looked at Xu Jiuyan's fluttering eyes, and said: "I am easy to win people's hearts because I am good to everyone, and more importantly, I treat every case as my own."
This time it was Xu Jiuyan's turn to stay: "Here again!"
"It's funny, go to the scene!"
Guan Zheng took Xu Jiuyan to the office, took equipment or something, and said, "What I said is the truth, you better remember every word I said, it is good for you."
"You're a chatter, if I remember all of them, wouldn't I be exhausted?"
Guan Zheng smiled and said, "So this will test your ability to extract information!"
Xu Jiuyan turned over the files in her hand several times and said, "Let’s take a look at the case first, do you want to read the file?"
Guan Zheng covered Xu Jiuyan's hand and said, "Don't look at it, it will affect your judgment!"
Xu Jiuyan nodded and said, "Okay!"
Guan Zheng said: "Has the forensic department called it?"
"Called, walking?"
Guan Zheng and Xu Jiuyan went downstairs, and the burned kTV could be seen from a distance. Guan Zheng said: "This is the most recent case we have come into contact with so far."
"This is great, it saves time and effort, and also saves travel expenses."
Guan Zheng got into the cordon, put on shoe covers, put on white gloves, and walked in.
After Guan Zheng went around for a few times, the whole house was scorched, the floor slab fell everywhere, and black dust kept flying up.
Guan Zheng asked: "Where is Old You?"
Jia Zhenkai came from behind and said, "Here it is!"
"Why are you? Where's Old You?"
Jia Zhenkai was a little embarrassed and said, "Chief Yuke is off today, as if he is going to see his son. I have already called and haven't left yet. I should be back soon."
Xu Jiuyan hurriedly broke the deadlock and said, "Mantou, don't worry about it. Guan Zheng prefers to work with acquaintances."
Jia Zhenkai nodded and said, "I know."
Guan Zheng did not like to explain anything to unrelated people, so he said: "Evidence must be collected in every corner here."
Jia Zhenkai nodded and said, "All right then."
Guan Zheng continued to pull Xu Jiuyan into it. Xu Jiuyan said somewhat unwillingly: "Did you deliberately make things difficult for the steamed buns? All the evidence is collected in such a big place. You should be his god."
"Don't be so arrogant as I thought. The fire scene is the most difficult to investigate. All the evidence was submerged by the fire, so we must try our best to collect evidence."
Xu Jiuyan nodded, and Guan Zheng asked, "Where is the fire source?"
"how could I know?"
"it's here."
"Here? Hy?"
Guan Zheng squatted down and said, "There are traces of anxiety here, indicating that the country is on fire, and the area is very large. It can be known that a glass bottle was once placed at the door, which contained the inflammable fire. Taste."
Xu Jiuyan looked at Guan Zheng with suspicion, then opened the dossier in her hand and screamed: "It's exactly the same as what's written here, should you change your career to become a magician? Learn from Song Ming and become an idol every minute."
"Can you make money?"
Xu Jiuyan rolled her eyes, this person really only cares about money.
Guan Zheng stood up and said, "Where is the surveillance?"
"I have taken it back, I haven't had time to see it yet."
"Is this kTV clean?"
Xu Jiuyan tilted her head and said, "Anyway, there is no record."
"Go back and check all the people present at the kTV at the time, including the staff."
Xu Jiuyan wilted in an instant, and said, "So many people! Really check!"
Guan Zheng said: "There is a murderer among these people, do you want to investigate?"
Xu Jiuyan suddenly became energetic and said, "How do you know?"
Guan Zheng said: "Although there is very little evidence in the arson case, it is easy to investigate. Do you know why?"
Xu Jiuyan thought for a while and said, "Because the scope of the search is limited and the motive for committing the crime is limited."
"The second question, if you are asked to paint a portrait, what kind of person do you think is more likely to set fire?"
"May not be older than 25 years old, male, very impulsive personality, belongs to the revenge personality."
"Why is it a male?"
Xu Jiuyan thought about it, and said: "Because women usually choose to retaliate against innocent people instead of involving most of the innocent people."
Guanzheng nodded and asked, "Then why is the personality very impulsive?"
"Because arson usually has a tendency to retaliate against the society, and it is often a crime."
Seki said: "As you said, arson usually has a tendency to retaliate against society. This does not mean impulsive character. Because they will prepare crime tools, gasoline or other things in advance. What do you think of this?"
Xu Jiuyan was asked again: "Um..."
"You should say that, be prepared and you must use it. Even though many arsonists have prepared tools for committing crimes, but because of some experience, they give up committing crimes.
Xu Jiuyan nodded, and Guan Zheng asked again: "Arsonism refers to the deliberate and purposeful arson that is committed repeatedly under various circumstances, but why is it a revenge crime? How can it not be arsonism?"
"Um..." Xu Jiuyan couldn't answer again.
Guan Zheng turned around abruptly and said: "You can answer this question. Let me repeat what I said. Arsonism refers to the deliberate and purposeful arson carried out many times under various circumstances."
"Ah! I see, arsonism is committed many times, but there is no similar case in this case!"
Guan Zheng nodded and said, "So, this case is not too difficult. Did you give the body to Xiaohuan'er?"
"Should be sent over, I have called."
Xu Jiuyan pulled the government off and wielded her perseverance, and asked: "What does arsonism come from? Tell me in detail."
"In 1992, Douglas and others once proposed the types of arsonism, namely, excitement-driven arson, carnival arsonists, and intensive arsonists. This type of people are mentally ill. They have no needs and blindly like everything and fire. Related stuff.
Later, some psychiatrists thought that arson might also be to satisfy one's own sexual needs, and believed that they were satisfied in the process of arson. Most of them have behavior problems, are prone to impulsivity, and are overactive. "(End of this chapter)
