Serial sin

Chapter 475 Deviation
In Ouyang Shuangjie's opinion, the murderer should have executed Du Zhongping during the daytime. It is not difficult to understand why he chose the grave of the woman who was killed by Du Zhongping that year, but running up to execute Du Zhongping in the middle of the night is somewhat unreasonable.I hope that one should not easily change one's own way of doing things, this change made Ouyang Shuangjie a little confused.

Ouyang Shuangjie still didn't believe that the murderer's style had changed. He felt that there must be some meaning in it that he couldn't comprehend.

Xie Xin said: "Could it be that he encountered some emergency and had to do it hastily?" Ouyang Shuangjie shook his head: "No."

Back at the bureau, Russell was already waiting in his office.

"Unfortunately, I didn't catch up. I just came back from Yundu and heard that there was a new case. I wanted to rush to the scene, but Director Xiao said that you will be back soon. I was thinking that I might rush to Huanghua The dishes are going to be cold. So I'll wait for you in your office, don't you mind?" Russell came forward with a smile, and Ouyang Shuangjie also smiled: "Of course I don't mind."

After sitting down, Russell asked Ouyang Shuangjie to explain the new case. After hearing it, Russell said: "It seems that the murderer of the Red Border Gate case should have done it. Captain Ouyang, the murderer committed the crime twice without leaving any complaints." The police have useful clues, it seems that it will be very difficult to solve this case!"

Ouyang Shuangjie nodded, Russell was right.

Originally, in Ouyang Shuangjie's view, another incident might help the police to solve the case, but now it seems that not only is not the case, it even deviates from some of his previous inferences.

Russell continued: "I learned from Bureau Xiao that currently Captain Ouyang locates the murderer in the two, no, three cases now, on people with mental problems, and conducts investigations based on some of the characteristics of the murderer. I created a psychological portrait, and even asked people to search all the psychological clinics and psychiatric departments in Lincheng. I really want to know what the basis for the psychological portrait is. In addition, you have locked in the investigation of Lincheng psychological clinics and psychiatric departments. A suspect?"

Ouyang Shuangjie frowned slightly, this old Xiao, why did he tell Russell everything?Even if the bureau agreed to allow Russell to conduct an interview, shouldn't there be a choice about what to say and what not to say?

Seeing Ouyang Shuangjie like this, Luo Su smiled: "Captain Ouyang, you also promised me to follow up and interview, if I didn't have other jobs in hand, I would have stayed in your team .”

Ouyang Shuangjie also laughed, and he said: "There is such a thing. In fact, the full name of psychological portrait should be criminal psychological portrait. Erman proposed a three-variable system. He believed that the criminal environment, criminal psychology and criminal behavior not only had a causal relationship, but also interacted with each other. Changes occur, as our old Chinese saying goes, the difference between living with a good person or living with an evil person. Once his psychological character changes to the bad side, it will eventually lead to crimes. This is a causal chain. Psychological profiling is based on the principle of consistency and interaction between criminal behavior and criminal psychology, and analyzes the criminal's psychological characteristics based on his behavioral characteristics, so as to obtain his gender, age, occupation, culture, personality, living habits, etc. Behavioral, psychological, physiological, and social characteristics, it changes the focus of the past research on the causes of crimes, that is, what we call the motives for committing crimes, and uses the inverted etiology of criminal psychology to deduce other crimes from the behavior of crimes. psychological characteristics, as well as the characteristics of his environment."

Russell listened with relish, and Ouyang Shuangjie coughed twice: "Look at me, this talk is too far."

Russell said: "It's okay, it's very exciting. I didn't expect the application of psychology to be so extensive and practical. I'm not afraid you will laugh. In fact, I have read some books on psychology, but I just can't calm down. Come on, I can’t look in. By the way, what’s the result of your investigation?”

Ouyang Shuangjie shook his head and said: "Not yet, psychological profiling has its basis, but it also has great limitations. Generally speaking, psychological profiling is more applicable to serial cases, because only Only in this way can we have more materials to accurately describe the characteristics of criminal suspects. Of course, it is not a panacea, especially for people who have serious psychological problems but have not lost their self-awareness. It will be relatively lower, because they have psychological problems, and their views on some people or things are different from ordinary people, and his difference is not great, and sometimes it is only at a certain point. If we If we can’t grasp that point, it is very likely that our portrait will have a big deviation.”

Russell nodded slightly, indicating that he understood: "Then what does Captain Ouyang think next?"

As a reporter, he was conscientious and kept asking questions.

Ouyang Shuangjie said that he hadn't thought it through yet. After all, such cases were not common. Due to the occurrence of Du Zhongping's case, he felt that there might be some deviations in his previous portrait of the criminal suspect, so he had to redo the two cases. The similarities and differences were re-examined, and then appropriate changes were made to the previous portraits, trying to be more accurate and catch the murderer as soon as possible.

Russell only stayed for an hour before leaving. He knew that Ouyang Shuangjie's time was precious.

He didn't ask Ouyang Shuangjie if he already knew that he had been to Wei Yangfan for treatment, and Ouyang Shuangjie didn't take the initiative to mention it, but Ouyang Shuangjie felt that Russell was just mentioning his interest in psychological clinics, hospitals and psychiatry departments. During the investigation, there was an unusual brilliance in his eyes. Russell should have known in his heart that Ouyang Shuangjie had discovered his secret.

It’s not clear, it’s just everyone’s tacit understanding. After all, Russell’s going to Wei Yangfan doesn’t really have any psychological problems. Wei Yangfan has also said his purpose and motivation. As a reporter, he has a certain professional sensitivity and curiosity. A very normal thing.

Ouyang Shuangjie didn't have the time to figure out Russell. At this moment, he hoped to find out the line between Zhuang Dazhu's case and Du Zhongping's case, and then eliminate their differences.

The two cases seem very similar, but why did the "judge" choose to "execute" Du Zhongping in the middle of the night?This is contrary to the principle of deterrence he advocated. What is the reason?
Ouyang Shuangjie lit a cigarette, sat on the sofa, closed his eyes and thought carefully, but he didn't have a clue.

Did I make a wrong judgment somewhere, and something went wrong?

Ouyang Shuangjie stood up, walked to his own whiteboard, wrote Du Zhongping's name on it, and then circled a few small details, then stared at the whiteboard in a daze.
