Hearing Yu Fan's words, everyone gasped.

Chen Jiaoyang urged Yu Fan: "What are you talking about?" ”

Yu Fan said to everyone: "Every behavior is not accidental, it reflects a person's current psychological state, and a psychological state will have its own unique behavioral characteristics." Finding these characteristics can greatly narrow the scope of the suspect's investigation. “

Yu Fan said to Zi Yan: "Officer Zi, please tell your colleagues, let everyone hurry up and have lunch, and then we will gather in the conference room, and I will draw the suspect to everyone." ”

Zi Yu didn't understand and asked, "Painting?" ”

Yu Fan said with certainty: "Yes, it's troublesome to police officer." ”

Zi Yan seemed to understand: "Oh, okay, I'll go and inform." Then he strode out of the conference room.

After Zi Yin walked out, Guo Na came over and asked Yu Fan, "Brother Yu?" Are you going to do a psychological profile of a suspect? ”

Yu Fan nodded with satisfaction and said to Guo Na: "It's so smart, it seems that you also understand this." Let's profile this suspect together. ”

Chen Jiaoyang interrupted the two of them: "Wait, wait." What profiling? I seem to have heard you say it last time, but I haven't figured it out, what is the profile you are talking about? ”

Guo Na explained for Yu Fan: "Profile (also translated as profile) refers to inferring a person's psychological state according to his behavior mode, so as to analyze his personality, living environment, occupation, growth background, etc. In the 70s of the last century, it was officially proposed by the FBI and used to solve criminal cases. ”

Chen Xiangyang said with admiration: "It sounds like a fortune teller, uh no, I mean that kind of god operator." ”

Yu Fan said humbly: "Actually, it's not that magical, these people just love to observe and think more." Let's go eat first and come back later. ”

Although there was a horrific vicious fire incident last night, life still has to go on, and the town is still running, but the fear and worry on everyone's face are more solemn, yes, the expression they saw on the first day they came to the town.

There were many small restaurants in the alley near the government office building, and the three of them chose a noodle restaurant with a small family, and they hurried back after eating the meal.

As soon as I returned to the conference room, there were already several people sitting in the conference room, and Officer Zi Yan was also there, laying something on the conference table with his colleagues, Officer Zi was really efficient, he didn't drag it out at all, and he finished eating in about 20 minutes and notified his colleagues.

Zi Yan saw that Yu Fan and the three of them were back, and beckoned them again and again, motioning for them to come over. The three of them walked over, only to see that there were a lot of pens on the conference table, all kinds, ballpoint pens, watercolor pens, pencils, gel pens, and even brushes, and Zi Yan and his colleagues were laying paper on the table.

Yu Fan asked curiously, "What are you doing?"

Zi Yan explained: "Didn't you say just now that you wanted to draw the appearance of a prisoner? I got the pen and paper ready, the time was too short, I didn't ask you what pen you wanted, anyway, we have it here, I'll just come around. ”

Yu Fan and the three of them were made to cry and laugh, and Officer Zi Yan obviously misunderstood the meaning of "portrait".

Chen Jieyang explained to Zi Yu: "Officer Zi, you are mistaken, what we call portrait is not a stroke, but a scientific depiction method to describe the characteristics of criminal suspects. It's the kind used by the FBI in the United States. Chen Jieyang is now learning and selling, and he seems to be very professional, pretending to be forced to leak.

Zi Yan smiled awkwardly and scratched the back of his head. At this time, there were more and more people entering the conference room, it seemed that everyone was very fast, Director Jin also came, and when he entered the door, he took the initiative to smile and wave to greet Yu Fan and them, and after coming in, he pulled a stool from the side and sat down.

Zi Yan glanced at it and handed over a message to Yu Fan: "Consultant Yu, it's almost time to start, right?" ”

Yu Fan nodded: "Hmm." ”

Zi Yan clapped his hands twice, signaling everyone to be quiet, everyone quickly stopped talking, their expressions became serious and serious, and Zi Yan said to everyone: "XA colleagues, I think many people have seen it in the past two days, so I won't introduce it much." This morning they helped us figure out how to set fires, and their professionalism is really worth learning from. The facts of the case now seem to be an extremely bad and premeditated arson incident, and then I will ask a consultant to make a picture of the suspect...... Draw...... Draw the side? Officer Zi was clearly not familiar with the new term.

Chen Frameyang reminded beside him: "It's profile." ”

Zi Yttrium: "Yes, profile, please consult with you." ”

Yu Fan took a step forward, and everyone looked at Yu Fan with expectant eyes, some of them pressed the gel pen out of the pen, and some of them had already put their hands on the keyboard, ready to record. This is also the first time Yu Fan has faced this kind of occasion, and it is interesting to think about it, an engineering man who does fine chemical business will appear at the police station one day and speak to the police, because Yu Fan lived for more than 30 years, in addition to handling household registration identity information, he has never even been to the public security bureau.

Yu Fan began: "First of all, everyone has basically understood the criminal modus operandi, the first day pretending to be a maintenance worker, replacing the modified deadly incandescent lamp in the warehouse, and destroying the monitoring system and fire protection system at the same time. ”

A young police officer next to him complained: "Hey, why does the monitoring system fail at every critical moment, it's really bad luck." ”

Yu Fan said with a smile: "Actually, this is not accidental, and the bloody plot in the TV series is not reasonable. Surveillance looks the most useful, but it's also the most useless, because everyone knows where your camera is facing, and there are 10,000 ways to 'blind' this rigid guard before a suspect wants to do something bad. The real deterrent should be invisible surveillance, you don't know where I am, where I came from, how to arrest you. ”

Guo Na added: "Just like the law of nature, karma, good and evil will be rewarded in the end, but you don't know what day it is." ”

Yu Fan nodded in approval, and then said: "According to the latest records, the supermarket owner, warehouse keeper and other relevant people have good interpersonal relationships and have no enemies, so it can basically be ruled out that this arson case is aimed at individuals." ”

Director Jin asked again: "Then what is the motive of this arsonist?" ”

Yu Fan did not answer Director Jin's question, and then said above: "Through the previous file and the clues of this arson case, there have been 5 consecutive arson cases in such a small town, and it can be basically inferred that this should be committed by the same arsonist. So I have every reason to suspect that this is an out-and-out - serial arsonist! ”
