Hearing Yu Fan's reasoning, everyone began to write.

Yu Fan said to Director Jin: "Just now you mentioned the motive for committing the crime. From the perspective of criminal psychology, the motives of arsonists are generally divided into the following types: concealment of crimes, political motives, conflicts of interest, revenge plots, and intentional sabotage. ”

While speaking, Guo Na used a pen to write these five motives on the clue wall.

Yu Fan continued: "Analyzing them one by one, the fire point is just an ordinary warehouse, and the victim is just an ordinary warehouse keeper, without any special social identity, and arson cases of concealing crimes generally occur in copywriting deposits, so the motive for concealing crimes is ruled out." As he spoke, Yu Fan crossed out the "hidden crime" with a pen.

Yu Fan: "Politically motivated arson can also be ruled out, because so far we have not received the political stance that the arsonist wants to express, and in general, the arson case of "expressing a political stance" will be organized to publicize the responsibility for this matter as soon as possible. Yu Fan crossed out the words "political position" again.

Everyone present carefully recorded Yu Fan's every word.

Yu Fan continued: "The revenge plot and the conflict of interests, we have roughly analyzed it just now, and it is unlikely. "Cross out

"So that's the only motive left for 'vandalism'?" Yttrium reacts very quickly.

Yu Fan pointed at yttrium with the pen in his hand: "Ding Dong, that's right," and then continued to say to everyone, "The desire to destroy a serial arson case is not the same as an ordinary crime, and the criminal inducements of serial arsonists are nothing more than two - sex and power. ”

Guo Na wrote "sex and power" in the center of the clue wall.

Yu Fan continued: "The purpose of their arson is to satisfy their perverted desires, so after they set fire, they will definitely watch their 'masterpieces' near the ignition point, and they enjoy the pleasure of burning, which makes him unable to extricate himself. ”

Yu Fan pointed to the location of several fires marked on the map of the town with a pen: "In the past seven months, there have been five vicious arson cases in a row. The first was a textile factory in May last year, the second was a food factory at the end of August, the third was a garment factory in October, the fourth was a garment factory in mid-December, and the fifth was a department store last night. Have you found any patterns? “

Chen Jieyang spoke: "Well, the interval seems to be getting closer and closer. ”

Yu Fan pointed at Chen Frameyang with the comparison in his hand: "That's right! The time between crimes is getting shorter and shorter. ”

One of the policemen in the room asked, "So what does this mean?" ”

Yu Fan: "It shows that this arsonist's desire has become stronger and stronger, and he is no longer as long as he was at the beginning." Desire is something that is difficult for human beings to control, and once neglected, it will continue to expand like opening a Pandora's box, and eventually swallow itself. ”

Yu Fan pointed to the map of the town again: "I think that at first, the arsonist had a certain conscience, the arson point and arson method he chose would not cause much harm to people, and most of them chose the location of the suburbs, and they were very careful, each time the location was far away, he just enjoyed the pleasure of burning, he felt that he was controlling the flames, but he didn't want to cause trouble." But this time it's different! Yu Fan's pen fell in the very center of the town.

"This time, the arsonist chose the department store in the center of the town, and it was carefully planned and planned for a long time, because the economic loss caused by the burning was huge, and there were also deaths. Why is it so serious this time? So abnormal? Yu Fan asked everyone rhetorically.

Another officer stood up and replied, "Maybe he was stimulated by something during this time?" ”

Another police officer also expressed his opinion: "Or maybe he didn't control it well? ”

Yu Fan shook his head: "We don't know the reason for this for the time being. But one thing I'm sure is that he needs an 'audience' more than ever! He is no longer satisfied with appreciating his 'work', he needs to share it with others. The flame's irritation on him had begun to wane, and he needed to satisfy his desires with stronger flames, and his swelling desires had eaten away at his sanity. His beastly nature is constantly evolving, he is no longer the same person, since last night, he has been completely out of control! “

There was a tense atmosphere in the air, a gust of wind blew open the window, and the comrade policeman by the window got up and closed the window.

Yu Fan said to everyone in a calm tone: "The troublesome thing may still be to come, the first arson and the second time are 3 months apart, the second arson and the third time are 2 months apart, the third and the fourth time are 1 month apart, and there is only two weeks between the fourth time and this time, the time is shortened so quickly, so what about the next time?" “

Everyone was startled, even more nervous, and looked at each other.

Director Jin sighed, but asked Yu Fan very calmly: "Then Consultant Yu, what do you think the next time should be?" ”

Yu Fan lowered his head and pondered for three seconds, raised his head, and said slowly: "At any time." ”

Everyone present heard this astonishing conclusion and began to communicate with each other, what can be done? I haven't figured it out this time, but the next one is coming, so it's overwhelming and unprepared. “

Yu Fan continued to add: "Moreover, next time, the nature will definitely be worse than this time, it may be far beyond our imagination, we must catch him before this!" ”

Zi Yan asked anxiously: "But we don't know anything about him now, how can we catch him?" ”

Yu Fan took a light breath and said, "The characteristics of the person you are looking for next are as follows. Everyone picked up their notebooks and began to record what Yu Fan said.

"Male, about 50 years old, between 170~180 tall, highly educated, high IQ, but now engaged in a certain amount of manual labor, his nails are very clean, he has a beard, when you see him, if he is wearing a black or dark shirt, you don't have to be surprised. When he was young, he was absent from his father, or the relationship between father and son was strained. Animal cruelty, bedwetting. used to have a sensitive personality and a certain pleasing personality, that is, he wanted to be recognized by others and wanted to do everything he could. Strong writing ability, like to publish articles or opinions to the outside world. There is a certain social barrier that can make them uncomfortable in a crowd. When someone he knows well walks up to him, he will pretend not to see him or slip away in a hurry because he doesn't know how to say hello. He has a strong desire to control and likes to lead others by the nose. Well, that's about it. Yu Fan described the suspect at a very fast pace.

Director Jin spoke to everyone: "Sort out what Expert Yu just said, sort it out word for word, distribute it to everyone, and then issue a reward order throughout the town, and then notify those media to let them publicize this profile, mobilize all forces to find someone who meets this characteristic, and be sure to bring him to justice before he commits the next crime!" You all know what to do, right? Let's go! ”
