Xu Jiuyan quickly got into the car and went straight to the bureau. Pen ~ fun ~ pavilion www.biquge.info

Xiao Lin in the archives saw at a glance that Xu Jiuyan was different, and said, "Yo, Xiao Jiu has become beautiful today, so good-looking." ”

Xu Jiuyan smiled slightly and said, "Yes, thank you." ”

The sound of Xu Jiuyan's high heels was even and orderly, Li Chongyang heard it from afar, Li Chongyang waved to Xu Jiuyan from afar, and said, "Do you know how to clean up today?" It's nice to be like this, how pretty, isn't it? ”

Xu Jiuyan smiled and said, "Wasn't I beautiful before? ”

"Beautiful, if it's not beautiful, how can you get the eyes of our political master?"

Xu Jiuyan smiled slightly and said, "I will be more beautiful in the future." ”

Li Chongyang nodded and said, "Did you stay up all night last night?" ”

Xu Jiuyan shook her head and said, "No." What's wrong? ”

Li Chongyang pointed to Xu Jiuyan's dark circles and said, "You have dark circles, you didn't use a concealer pen or anything to block it?" ”

Xu Jiuyan looked in the mirror on the side and said, "It's okay, don't care about these details." ”

Li Chongyang smiled and said, "Yes." By the way, how did you get the case? ”

"I was about to tell you this, I re-sorted it, age and gender and he is good at makeup, this should be correct, no need to change, but I think his position needs to be re-chosen.

The fact that he painted the victim with elaborate make-up shows that he is proficient in this type of work, but does that mean that he must be engaged in this kind of work?

He chose to commit crimes in the playground, which is a place with a lot of people, why did he choose here? This is because the playground is a place of yearning for him, which also means that his childhood is incomplete, and he may have experienced family divorce at an early age, or something else.

What else can you do if you take a photo with a point-and-shoot camera other than because the point-and-shoot camera takes pictures quickly? Because he has a child's heart, this also fits the inference of the previous article.

He prepared the most elegant makeup for the victim, which can also be said to have a certain paranoid personality and a pretentious heart. So why beat the victim again? Because of his nature and incompetence, he can only be satisfied through violent means. ”

Li Chongyang nodded and said, "That's right, your profile is much more detailed than the last time, and ah, I think this person's characteristics are already in place." I'll check it right away and re-screen the suspicious people. ”

Obviously, it is very detailed, but some personality traits do not appear in people's files, and the information in the files is still limited after all.

Xu Jiuyan asked, "Why is this happening?" ”

Li Chongyang said: "This is the difference between you and Guan Zheng, every psychological portrait of Guan Zheng can lock clues from the file as much as possible, which will also provide us with more clues and save police resources." ”

Xu Jiuyan nodded and said, "I know, but I may not be as comprehensive as Guan Zheng now, I'm really in a hurry, but I still don't know what's wrong." ”

Li Chongyang patted Xu Jiuyan on the shoulder and said, "Don't be too anxious, take your time, it's not so easy to solve the case, you've only been here for a few days, don't worry." ”

Li Chongyang continued to screen people, but Xu Jiuyan felt as if she had fallen into a trap.

Shi Jinyu passed by the office and saw Xu Jiuyan flipping through the information randomly, a little at a loss. Shi Jinyu knocked on the door and said, "Xu Jiuyan, come to my office." ”

Xu Jiuyan raised her head in confusion and followed Shi Jinyu into the director's office.

Shi Jinyu poured Xu Jiuyan a cup of tea and said, "Come, drink some water." ”

"Thanks, no need."

Shi Jinyu said: "I came to you to talk about this case, that is, the playground murder case you are working on, and I have something to tell you." ”

Xu Jiuyan nodded and said, "This case is still being solved, although it is a little uncomfortable, but I believe that I have the ability to handle the case alone." ”

Shi Jinyu said: "I don't doubt your ability to handle the case alone, after all, you are not from a professional class, so I have to talk to you about some skills." I am an early criminal psychology expert in China, so I have some professional skills to tell you.

Guan Zheng is indeed talented, and his attainments are indeed very high, but he is not by your side now, so I can only tell you about it. If you want to solve this case, finding people is one thing, and more importantly, finding evidence. Evidence is tangible, but criminal psychology is intangible.

Criminal psychology is an auxiliary tool, and traditional criminal investigation is the magic weapon. As soon as you come to the bureau, you will study criminal psychology with Guan Zheng, Guan Zheng is an expert, and he can freely switch between traditional criminal investigation and criminal psychology, and you may not be so easy to accept.

When you give the direction of investigation according to criminal psychology, you should also consider the power of traditional criminal investigation, people will not change, and the evidence will not change, if you want to solve this case, you must think backwards, see everything about the murderer, and stop the murderer before he commits the crime, which is the meaning of the criminal police. ”

Xu Jiuyan asked a little incredulously: "You mean, this person will still commit crimes?" ”

Shi Jinyu asked, "Don't you think?" Such a murderer usually has no clear motive for committing the crime, which means that he may have committed the crime because of a change in his psychological condition, so it is difficult for him to stop. ”

Xu Jiuyan nodded and said, "I know, I will find this person as soon as possible." ”

Shi Jinyu sighed and said, "I hope you can understand what I said today, these can help you solve the case better." ”

Xu Jiuyan came out of the director's office and happened to bump into Jia Zhenkai, so she said, "Go to the playground again." ”

"Still going?"

"How can you solve the case if you don't go?"

Xu Jiuyan parked her car at the entrance of the playground, and the normally open playground was still crowded, and the blocked cordon did not have any impact on tourists.

Xu Jiuyan and Jia Zhenkai drilled into the scene of the murder, and the traces of evidence were still on the ground. Jia Zhenkai asked: "The evidence here is limited, and it is like this how many times you look at it." ”

Xu Jiuyan suddenly asked, "Haven't we visited the parade of floats yet?" ”

"yes, what's wrong? Do you want to go now? ”

"That's right."

Xu Jiuyan contacted the relevant person in charge and quickly found the team of the float parade.

The producer of the float parade was a very young woman, Jia Zhenkai showed his ID and said, "Hello, I am from the Criminal Investigation Brigade of the Municipal Public Security Bureau, and I want to ask about your team's loss of puppet coats." ”

The woman nodded and said, "Hello, my surname is Ren." I don't know exactly what you're talking about about the puppet jacket, I'm not in charge of this, but if it's weird to ask, I'd like to say that we haven't lost the key to our dressing room for a while, and no one has told me about the loss of the dolls. This is the strangest thing, because what is lost is a spare doll, and we haven't touched it at all, so no one cares if it's lost. ”
