"As the saying goes, each other is born from the heart, what is in the heart, what the person looks like. That's why I worked as a prison guard in Yenching Prison for eight years, reviewing the criminal files of thousands of people and looking at everyone's facial features in detail. ”

"When it's over, others ask me if it's natural, every time I go back, why don't I see that you also have this ability? If I hadn't spent eight years in prison to observe, I wouldn't have this skill. ”

"You're a funny boy, you actually said that I drew it by intuition, and you drew one for me too?"

Zhang Bin's face turned red, and he didn't say a word, and finally Sun Jianguo made a round, patted Chen Jun's shoulder and said, "What clues are you missing?" Maybe we can discuss it, and I think my reasoning is not bad in this regard. ”

"Old grandson, you? yes, forget about you, come on, tell me about it......"

As he was talking, a shout came from outside the door: "Several comrades, the meeting has begun, and the director asked me to call you over." ”

Chen Jun said impatiently: "I know, I know, don't bother me, don't you see that I'm doing business?" ”

Sun Jianguo persuaded on the side: "Lao Chen, let's go over, after all, we are invited to come, if we don't even participate in the meeting, I'm afraid that we will fall into the mouth, and in the future, it will affect the relationship between the two bureaus." ”

Chen Jun was silent for two seconds and nodded in agreement, and several of us were relieved, if he continued to fight, we really didn't know what to do.

When I arrived at the conference room, the deputy director was flipping through the information on the desktop, and when he saw us coming in, he nodded and signaled to sit down, and after waiting for someone to sit down, he closed the information and said: "Yesterday, we sent people to raid the pornographic establishments in the entire Guangbei to investigate the information of the victims. ”

"So far there has been no result, but last night, we unexpectedly got an important clue, Zou Ruikang, a migrant worker from other provinces, and Wang Xiaodi, a fellow villager, came to Guangbei City to work in April, because the two of them work inconsistently, so the two came to Guangbei City after they separated, Zou Ruikang has been trying to contact Wang Xiaodi, but there is no news. Based on his description of Wang Xiaodi, we compared several victims and found that one of them was very similar to Zou Ruikang's description. ”

"We sent people to Wang Xiaodi's hometown overnight, collected fingerprints and hair left in his home, and asked the local police to assist in identification, and this morning, the results were fed back to us, and through comparison, it can be confirmed that one of the victims is Wang Xiaodi, a migrant worker from other provinces."

"We are now sending someone to investigate the shampoo salon where Wang Xiaodi worked before his death, and there is no feedback yet."

"What I just said is the first situation, the second situation is the homicide that happened in the morning, recently the murderer has become more and more crazy, the frequency of the crime has increased greatly, so far it is the seventh case, the scene of the crime has been to the morning Dajia has also been, the scene of the scene does not need me to say more, the evidence left is still very small, with these clues are not enough to directly launch the pursuit of the suspect."

"But this time we found clues that have not appeared before, the murderer used to drive on the intersection or concrete road, afraid of leaving rut marks, but yesterday there was a rupture in a section of the road near the crime scene. When the murderer drove the vehicle past at night, he suddenly found a large pothole in front of him, and in a panic, he urgently hit the steering wheel, causing the vehicle to drive into the dirt on the side of the road, leaving clear tire tracks. ”

"Forensic experts repeatedly analyzed and compared tire tracks and locked down the model of the vehicle. It is a micro truck of only 0.6 tons. The front cab can seat 2 people, and the rear can also tow goods. There are 1,200,000 of these trucks in Guangzhou, and they are mainly used by renovation workers in the construction industry to transport small quantities of materials, or to a small number of private drivers who make deliveries for a living. I've sent people out to collect clues, but Guangbei is so big, it will take a while to get results. ”

"I'm bringing you together now to ask if you've found any special clues or subtle details after going to the site this morning."

It seemed that he was very unhappy to be refuted before, Chen Jun stood up and said, "I'll tell you about this case today, otherwise some people will think that I am here to eat and drink." ”

"First of all, the escort lady is a special profession, and once she is killed, it is almost impossible to track down the murderer. Most of the escort ladies and their clients do not know each other, and it is impossible to discover the identity of the murderer through ordinary social relationship investigations. If the escort lady is working in a fixed area such as a hair salon or nightclub, the escort lady may visit many times, or be seen and leave clues. ”

"But judging from their dress, they should all be the lowest street girls. Street women solicit customers on the side of the road, usually alone, sometimes picking up several people in one night, and no one will pay attention to what prostitutes they are leaving. ”

Speaking of this, Chen Jun stopped and glanced at the deputy director: "What I said is fine, right?" I'll just go on. ”

The deputy director was not angry about his previous words, but asked him to continue with some anxiety, Chen Jun did not put on a show this time, but said with a serious face: "The gangster's choice of the escort lady to commit the crime is not accidental, but the result of careful selection. The purpose of the gangsters to choose the escort ladies is mainly to kill them more confidently and easily. This proves that the gangsters are not physically strong, and even against women there is no certainty of victory. If a woman is violently attacked, the victim often resists and cries for help, and the slightest carelessness may lead to arrest. This refers to the first case, because the first victim was not an escort lady, so there was a fight with the gangsters. ”

"I went out last night to take a look, and the folk customs in Guangbei are still relatively conservative, and it is not easy for gangsters to lure women from good families to a certain place. And I don't think the public security in Guangbei City is very good, not as good as Yanjing, female citizens are more cautious, and generally don't care about strangers. In order to test this conjecture, I also deliberately asked a few women to try it. ”

"In short, there is so much nonsense, it means the same thing, the gangsters can't deal with the women of good families at all, and it is much easier to choose the escort lady. Escort ladies generally do not refuse the request of a prostitute, even if it is in the middle of nowhere. Since it is Miss Escort, the two sides must have close contact, and it is also convenient for the murderer to suddenly attack Miss Escort. These escort ladies were attacked in the arms of gangsters, and they often died before they had time to call for help. ”

"Then the question is, since you can directly have an apricot relationship with the escort lady, why do you want to kill them and rape or even destroy the corpse?"

Chen Jun said and looked at everyone, and everyone suddenly whispered, I vaguely remembered what Sun Jianguo said yesterday, as if it was to take revenge on women. At this time, Liu Yefang suddenly stood up and said, "Sexual change is too murderous? ”

Chen Jun looked at her suspiciously: "You know this?" There are very few about this concept in China now, right? I still know about it through academic exchanges with foreign countries. ”

Liu Yefang explained: "I read an article you published in an internal magazine, and it mentioned this concept. ”

"It turned out to be an apprentice, no wonder I have a bit of true biography." Chen Jun said with a smile, then turned his gaze to everyone and continued: "That's right, this is a very standard case of sexual change killing, gangsters don't kill people to rob money or sex, but to vent a kind of psychology of becoming too much. ”

"Killing, raping, and destroying corpses will make gangsters feel a lot of fun, far more fun than having sex with an escort lady. I also dealt with a similar case a long time ago, the murderer also cut off the woman's chest muscles and lower body after killing a woman, and the police chased him to Hedong to participate in the arrest, and finally captured the murderer. Through interrogating this person, I learned about the psychological characteristics of such murderers. ”

"Through continuous research on such cases, it can be confirmed that the prisoner is a serious psychopath, especially a serious necrophilia. As far as the case itself is concerned, the murderer had already had an apricot relationship with these escort ladies, but he still wanted to kill them and rape the corpse, and then cut off some parts of the corpse, which shows that his necrophilia is very serious. ”

"Necrophiles are mostly cowardly and incompetent people. In such a person there is a strong desire to dominate his sexual object, and this desire to satisfy himself occupies a very important place in his sexual satisfaction. Corpses will never rebel against their commands, so they prefer to choose corpses as sexual objects. They may be a failed person with repeated setbacks in their social life. Unable to control the world of the living, they turned to the world of the dead. He was a powerful ruler in the face of the dead, and the corpses bowed down to him, not refusing his demands or ridiculing him for his incompetence. In short, he is in a dominant position in this behavior, and he does not have to worry about failure and setbacks. Incidentally, necrophils are often accompanied by obvious psychosis. Therefore, when the murderer is found and arrested, it must be extremely careful. ”

"Through my previous experience, combined with this case, we can roughly draw the following three points: First, the murderer has a clear tendency to become too sexual, and the mental patient should be investigated in the city's psychiatric hospitals or specialized outpatient departments to understand this aspect. Second, the murderer's personality should be cowardly, and special attention should be paid to cowards, introverts in key groups. Third, judging from the fact that the murderer can effortlessly take away many escort ladies, the murderer is obviously proficient in prostitution and is an old prostitute. People who have been involved in prostitution or sex crimes should be screened throughout the city, and it is very likely that the murderer will be found. ”

"I think with the clues of the ruts, these conditions can almost greatly narrow the search scope of the suspect."

The deputy director stood up and walked up to Chen Jun, shook his hand gratefully and said, "Thank you very much for putting forward such a valuable opinion, is there anything else else else you want to say?" ”

At this time, Sun Jianguo stood up and said: "I suggest that the police should transfer manpower from the local jurisdiction to assist, Zhanhu District is a shantytown, there are many alleys and paths, if you don't live in it for a long time, there is no way to implement full control, which will lead to the murderer escaping." ”

The deputy director thought for two seconds and nodded: "Yes, we have also neglected this point, and I will let people deal with it when the meeting is dismissed." ”

In the time that followed, most people basically didn't talk about the part that Chen Jun and Sun Jianguo said. There are also a small number of people who put forward more novel ideas, such as the old criminal policeman who judged that the deceased belonged to the escort lady yesterday said that there is a possibility, the murderer does not necessarily live alone, maybe he may have a family, he did this to excrete the dark side of his heart, so as to prevent him from holding back some abnormal actions in daily life and violent himself.

Regarding these possibilities, the deputy director ordered people to record them one by one, and after waiting for a meeting, when no one came up with new clues, today's meeting ended. Back in the dormitory, Chen Jun returned to the table and continued to ponder the murderer's self-portrait, Sun Jianguo pointed at the side, and the two still didn't talk to each other. Seeing this harmonious scene, I almost forgot that Sun Jianguo wanted to beat Chen Jun yesterday with a black face and gritted his teeth.

Because most of the investigations are in charge of the police in Guangbei, the main task of our foreign aid is to be responsible for sorting out clues and providing direction for the investigation of the case.

Sun Jianguo and Chen Jun were busy until noon, a simulated portrait of the murderer appeared on the table, the three of us hurriedly went over to take a look, and there was a slight difference from what Chen Jun had drawn before, the ears were changed, and the eyes were slightly bigger than before, and there was no difference in the rest of the place.

Chen Jun picked up the portrait and looked at it to the left and looked at it, and finally muttered: "That's pretty much it, even if there is an error, it's not much worse, give it to the old man, just like this, the case dragged on for five months, and sure enough, the direction is not right, no matter how hard it works, it's useless." ”

Called the management of the dormitory and asked him to entrust it to the deputy director, and then Chen Jun dragged Sun Jianguo out of the door, listening to his tone, it seemed that he was going to go to the snack bar yesterday, Sun Jianguo didn't want to go, Chen Jun whispered in his ear, and then agreed.

At noon, a few of us walked around the public security bureau in Guangbei, although it was not big, we still found a lot of places that were more advanced than the Songhai public security bureau.

In the middle of the afternoon, Chen Jun and Sun Jianguo returned to the dormitory from outside, sitting at the table and not knowing what they were discussing, and after a while, the deputy director suddenly came to the dormitory, shook Chen Jun's hand violently, and his mouth fluttered with excitement.
