Chapter 4 Criminal Minds Portraits
"male?!"

Everyone in the police station, including Xia Yan, widened their eyes and couldn't believe their ears. Then they looked at Zhou Zheng with a hint of playfulness flickering in their eyes.

In this short and no contact time, they already knew that this new face was an intern.

They are all veterans in the team, and they understand that some newcomers like to be independent when they first come, and often express some opinions that highlight their own personality to show their existence.

"From the point of view of the murderer's modus operandi, what she chose was the state of the victim when she was drunk. This is precisely the method commonly used by female murderers to make up for their own lack of strength. In addition, the lives of these victims were all cut off. , It is also in line with the characteristics of love killing, why do you think the murderer is a man?" Xia Yan frowned and asked in puzzlement: "Would a male murderer kill and cut off a victim who has no intersection at all?"

"That's right! The murderer cleaned up every scene so clean, isn't it because he was afraid of leaking his information, which means that he was an acquaintance who committed the crime!" one of the criminal policemen echoed.

"Judging from the existing information, this is indeed the case. The possibility of a female murderer is extremely high. There is no financial loss in the three scenes. According to past experience, there are only a few motives for the murders, such as vendetta, love, and money. Killing, fighting, this scene is obviously a disguised love or vendetta!" Another criminal policeman added.

"Actually, we closely monitored Zhang Yunhu's girlfriend, Wang Qi, and found that her best friend Chen Siying had some unclear relationship with Zhang Yunhu. We just haven't found out whether Chen Siying has any contact with the previous two victims. When the three cases happened, Chen Siying always said that she was sleeping at home, that is to say, there was no alibi." Another criminal policeman said.

The detectives at the scene were all old people who had been with Xia Yan for several years. They judged from the very beginning that the murderer might be a woman. It was just that the team leader said such things. Moreover, they all had a kind of desire to suppress this kind of crime together. The feeling of a proud newcomer intern.

"Zhou Zheng, tell me what you think."

Xia Yan frowned even tighter, thinking that this intern was brought back by Bureau Qin after all, and he was also a student of Professor Fan, so maybe there was something unique about it.

Of course, if it was grandstanding, this matter would not be easily dismissed!
"The murderer, male, aged between 25 and 35, under 170 cm tall, thin, unmarried or divorced, withdrawn, not good at interacting with others, most of the time he prefers to hide at home, recently There should be no work during the time, he likes to drink or drink heavily, and occasionally goes to bars and other places at night, but he will be far away from the opposite sex. He should have been treated in the andrology clinic or the andrology hospital of a hospital in this city in the past six months or a year, X There are some functional problems and it is not so easy to cure, I can drive but I don’t have a car, and my place of residence should not be far from the scene of the crime..." Zhou Zheng enunciated very clearly while doing the portrait of criminal minds.

"Wait, let me interrupt. The distances between the three crime scenes are not close, and the second murder case is still in Midtown." Xia Yan's expression was a little strange. It's listening to the magic stick fortune telling.

"Subway." Zhou Zheng's eyes became sharper, and he said, "You can check the map. If I'm not wrong, the three murder scenes are all around the subway station."

Immediately, one of the policemen picked up the subway, and there were circles drawn at the three murder scenes. He immediately looked up and said, "Jianghai Line 15! Mingzhu Community, Heishi Street, and Changhuwan Community are all on Jianghai Line [-]. The time from the three crime locations to the subway station will not exceed [-] minutes!"

As soon as these words came out, the expressions on the faces of everyone at the scene changed, and they suddenly became serious, realizing that Zhou Zheng was not joking.

"But..." The criminal policeman just changed the subject and said, "The last train on Jianghai Line 24 runs at 1 o'clock in the evening. The victim Zhang Yunhu in the third murder case died at around [-] o'clock in the morning after forensic identification. The murderer could not catch up at that time. From the subway."

Swish!
Everyone's eyes were all focused on Zhou Zheng, waiting for Zhou Zheng's explanation, the way they looked at Zhou Zheng had already changed.

"The murderer's residence won't be too far from the scene of the crime. Think about it, if he can't catch the subway, how can he go home?" Zhou Zheng's sharp eyes became more intense.

"You mean..." Xia Yan's eyes widened suddenly, and the hair on his arms stood on end.

"The murderer should live in Changhuwan community!" Zhou Zheng said firmly.

"This... But this is all your guess!" Xia Yan's heart beat faster, he understood that when Professor Fan helped the police solve the case in the past, he used this method of criminal psychology portrait to delineate the scope, But the person in front of him is not Professor Fan after all, he still wants to be more sure, so as not to waste precious time in solving the case, and then said: "Can you explain?"

"What do you want to hear?" Zhou Zheng was indifferent, and he was still making supplementary analysis in his heart, inferring the murderer's psychology.

"Let's talk about why you think it's a man, not a woman. You haven't convinced me yet." Xia Yan's tone became less intense.

"You suspect that the murderer is a woman. It is nothing more than love or vendetta, and the so-called vendetta is motivated by love. The murderer in this type of case has very obvious psychological characteristics." Zhou Zheng shook his finger lightly. The thoughts in his brain are almost out of his mouth, and he can't keep up with his thoughts. "Love killings are often caused by irreconcilable conflicts between families, husbands and wives, and lovers. The murderers in such cases are often relatives or spouses, so they I will try my best to separate the relationship between myself and the case, then I will disguise the scene of the crime, and the disguise is not the murder method but the murder motive, then there are only two possibilities!"

Zhou Zheng stretched out two fingers.

"One is to kill by pretending to be rape, and the other is to kill by pretending to be rich. The special feature of the three murders is that the victim's life was cut off, and there was no loss of property. It does not conform to the psychology of pretending to be motivated. This is not love killing. A murderer can react."

The scene was completely silent, everyone was listening to Zhou Zheng's words carefully, and nodded unconsciously.

"Let's talk about vendetta..." Zhou Zheng's voice continued: "There are generally three psychological motives for vendetta murderers, personal enmity, revenge, and politics. In criminal acts, they want to vent their anger. It can often be seen that the means are extremely cruel. A variety of fatal injuries or post-mortem injuries, as well as the phenomenon of dismembering or throwing corpses, but there were no such signs at the scene of these three murders. Although the life roots of the three victims were all cut off, the murderer used very delicate and gentle The method of skin preparation was carried out, and apart from the deadly strangle marks on the neck, there were no unnecessary traces on the victim's body, no emotional outlet was found, and the clothes were stacked neatly, which obviously did not conform to the characteristics of a vendetta."

"Zhou Zheng, what you said makes sense, so according to your analysis, what is the motive of the murderer?" Xia Yan frowned even tighter. Unlike before, he was convinced by Zhou Zheng's reasoning.

"If it must be consistent with the conventional logical motive, then the most suitable motive is to kill people for money." Zhou Zheng said.

"Tucai?" Xia Yan was stunned for a moment, everyone's eyes widened, and they couldn't believe their ears. They didn't think about this motive at all, "No property was lost at the scene!"

"Actually, there are." Zhou Zheng pursed his lips and said with a smile, "The root of life has been cut off. For men, isn't this a precious asset?"

"This..." Xia Yan was numb, and suddenly felt that Zhou Zheng's smile just now was terrible. Could this be a reason that normal people can come up with!
"The murderer's purpose is not to kill, but for the life of these three victims. Killing is just a means to remove obstacles. After all, they will not be cut off willingly when they are alive." Zhou Zheng paused for a moment before continuing. Added: "Captain Xia summed it up very well. These three victims are all good-looking women, and they can be regarded as scumbags. This has become the target of the murderer's selection of prey. From the perspective of psychological results, these three victims Being able to succeed in the process of getting along with the opposite sex shows that they have certain "extraordinary features", which is what the murderer wants. This can also be seen from the careful skin preparation and neat incision. .”

"hiss……"

Everyone in the police force, including Xia Yan, couldn't help but gasp. Everyone couldn't help but feel their bodies shrinking. This feeling of being missed by others has an indescribably creepy feeling. .

"Take a step back, even if it is a female vendetta case, the method of venting will not take away the victim's organs, it is more likely to chop them up on the spot." Zhou Zheng analyzed methodically: "So, in essence, the three The serial homicide case is essentially a burglary homicide case, and if we change the way of thinking, the subsequent detection work will not be so difficult."

"This... this..." Xia Yan realized that he was still not perverted enough to understand that perverted mood. The expression on his face became very exciting, and he asked, "Why does the murderer want that thing?"

Xia Yan's question was the focus of the entire police force's doubts. Their thinking had froze at this moment, and they all stared blankly at Zhou Zheng. Unknowingly, the status of this newcomer in their hearts continued to rise.

"I would also like to thank the forensic doctor who carefully made the autopsy report for writing the details of the skin preparation into the report." Zhou Zheng first sent a rainbow fart to his future colleagues, and then said: "The murderer did this. The purpose is nothing more than not wanting the things that are taken away to have hairs on them, so imagine, why would he take away a piece of meat and still have to remove the hairs?"

"Could it be that you have some special hobbies?" Xia Yan was asked, and a curious question mark appeared in his head.

"What kind of special gameplay can a piece of meat that has no life reaction have!" Zhou Zheng shook his head and said: "The murderer took away so delicately and carefully, full of a sense of ritual, I'm afraid it's not as simple as collecting it. If I guessed correctly, he Might be eaten."

"?!!!"

The faces of the people at the scene became even more exciting, and they suddenly felt a stomach discomfort, Xia Yan's brows twitched wildly, and his whole body was a little numb.

Criminal police have been in this business for a long time and can meet any pervert, but this is the first time I have heard of such a pervert, it is too exaggerated!

the most important is……

What is the species of person who can see into the heart of a perverted murderer so thoroughly?
All of a sudden, the way people looked at Zhou Zheng changed again and again. The previous contempt and banter had long since disappeared, and there was even a touch of fear in the depths of their eyes.

"Preparing the skin gives me the feeling that it is like picking vegetables before cooking, removing the excess parts that cannot be eaten." Zhou Zheng added: "So, I judge that the murderer is still carrying a lunch box. Used to hold cut food."

"This is too perverted!" Xia Yan felt like retching when he thought about it. He found that he still didn't understand perverted enough. After seeing it, he asked, "The murderer must be gay, right?"

"Probably not." Zhou Zheng shook his head, and said solemnly: "If the murderer is gay, he will not eat the dead, but the living."

"..." The audience was once again speechless.

"This type of case can be regarded as a theft case when inferred, but it is also a perverted X crime. It can be inferred that the murderer is in the period of paying attention to the X relationship, and combined with the fact that the murderer may go to see a doctor because of the X relationship. It is speculated that the murderer is mostly between the ages of 25 and 35." Zhou Zheng's brain was running fast, and he became more confident in his expression, saying: "When encountering such a thing, if you are too young, you will feel self-defeating. When you wait for negative emotions, you often feel bad about yourself, but you don’t care about it; if you are too old, you will stabilize, even if you have problems, you can face it calmly and accept the result.”

Everyone at the scene nodded silently, gradually listening intently.

"Due to problems with physical sexual ability, the murderer has no way to provide a harmonious sexual life. He will have an inferiority complex, unable to establish a normal relationship with women, and even avoid contact with women."

Zhou Zheng continued to analyze.

"He may have had a girlfriend or been married, but he couldn't maintain the relationship, and eventually the relationship broke down. Then he should be single. And live alone, there will be no real estate under his name."

"I'm not in the mood to work in the near future, but I may do some part-time jobs to pay rent and other living expenses."

"He will suddenly kill people serially, indicating what kind of stimulation he has received in the near future. This kind of physical stimulation often comes from the medical certificate, and it is more likely to be a medical certificate with poor follow-up treatment results."

"So, the murderer should have had the experience of seeing a doctor within a year, maybe even within half a year, or a few months ago."

Everyone at the scene was dumbfounded, and they could understand the conclusions they drew, but if they were asked to analyze it, they would be confused.

"During the stimulation and impact of the follow-up medical certificate, the murderer will burst out a lot of negative emotions in a short period of time, resulting in certain psychological problems. The most intuitive manifestation is depression and withdrawn temperament. Such psychological problems will make him lose his appetite. , there is a phased thinning."

Zhou Zheng's thoughts turned faster and faster.

"Therefore, the murderer was thin and weak, so he couldn't beat the three victims, so they were selected close to the time when they were drunk, and because the strangle marks on the neck of the corpse had a downward angle, combined with the height of the three people, the murderer's The height is under 170."

The eyes of everyone at the scene became complicated. They vaguely felt that this was not a meeting to analyze the case, but rather a lecture on criminal psychology.

"Physical problems lead to psychological problems, and depression often leads to alcoholism. While alcohol paralyzes the murderer, it also aggravates the murderer's desire for X abilities. When you see those men and women who are feasting and feasting, you will want to make your own The restoration of his ability triggered the most primitive possessive desire in the theft case, so what would he think of when he saw those scumbags surrounded by the opposite sex at this time?" Zhou Zheng shook his fingers quickly, and the corner of his mouth curled up meaningfully. The curvature of the curve, asked and answered: "Complement the shape with the shape!"

"hiss……"

Everyone at the scene couldn't help but gasp. Such a perverted mentality can be analyzed so clearly that it almost made them feel chills down their spines.

"There was no trace of gnawing at the scene, and the method of cutting it was used, indicating that the murderer wanted to cut it up and take it away, and then eat it after returning home..."

Zhou Zheng's eyes gradually became sharper, his right hand was pinching his chin, and the speed of his mouth was also accelerating.

"Then bring a carrying tool!"

"From the perspective of the murderer's importance, there is a high probability that there will be something like a lunch box."

"As for the car..."

"The murderer has been drinking for a long time, coupled with no job, even if he had a car before, he may have sold it, so the murderer has no car."

"But he needs to take public transport!"

"Then... the radius of the area where the murderer can move will be very limited, and the crime will be considered in the area covered by public transportation, that is, the subway!"

"And the time of committing the crime will be controlled within the time of subway operation."

"So, the Changhuwan community has been exposed, but there is still a problem..."

"How did the murderer get close to the victim?"

The speed at which Zhou Zheng shook his fingers became faster and faster, and various possibilities were constantly filtering through his mind, and his thinking became more sensitive and meticulous.

"These three victims were discovered by the murderer, they should have been in and out of a common place, that is, the bar."

"The place where Zhang Yong, the deceased in the first murder case, appeared last was also a bar, so the bar is the thread that connects the three victims. As for how to get the victim to open the door, it is likely to deliver food. Combined with the introduction in the file, Zhang Yong, the victim of the first murder case, The cars of Yong and Zhang Yunhu, the victim of the third homicide, are parked in the basement, and they may be substitute drivers."

"hiss……"

Xia Yan and the members of the task force in the car couldn't help but gasp. After hearing Zhou Zheng's deduction, they couldn't help but sigh that there are such perverts in the world, and they were amazed at Zhou Zheng's thinking.

"The murderer cleaned the scene cleanly, which shows that he has a strong obsessive-compulsive disorder, and he will definitely not forget to close the door like the third murder case."

"Then the special point of change in this serial murder case represents a change in the murderer's psychology."

"He felt excited and thrilled after the body was found!"

"Not only that, but the interval between the third murder case and the second murder case is obviously shorter than the time between the second murder case and the first murder case, which shows that the murderer's desire is escalating."

"If the murderer is not caught as soon as possible, he will definitely commit crimes again in a short period of time, and he will choose a way to expose the body more, which will inevitably cause even worse social reactions and pressure from public opinion."

Having said that, Zhou Zheng's face became serious, and his eyes were sharper than ever.

"Captain Xia, according to the criminal psychology portrait I made just now, I am looking for such a tenant in the Changhuwan community. He works day and night, works part-time as a deliveryman or substitute driver, wears a helmet or hat, and carries a bag with him. There should be a lunch box and a murder weapon inside, and it should be easy to find after this area is delineated."
