Criminal Investigation Files

The meeting lasted until a little before noon, Fu Linjiang stayed and copied the materials with the second team, and continued to investigate the case in the afternoon.

Song Wen first took Lu Siyu to the cafeteria.Li Luanfang caught them by surprise these few days, and finally sent the old lady away, and it was rare for Lu Siyu to be lazy and not cook.

Lu Siyu was not too impressed with the food in the canteen of the Municipal Bureau, so Gu Ju delayed, and he didn't want to order takeaway, so he came over and ordered two dishes.

The canteens in the team are full of big pot dishes, and the master chef has a kind of skill. No matter what ingredients are used for stewing or frying, all the dishes will taste the same after they are cooked.The canteen is generally ventilated, and every time it's time to eat, the canteen is filled with this unique food aroma, which makes people half full.

Several dishes were placed on the plate, and Lu Siyu picked and picked like a bird, eating the bean sprouts one by one.

After a while, Song Wen ordered food and came over, sat next to him and said with emotion: "I didn't think the canteen here was so bad before, but now..."

"It's better to have something delicious in the cafeteria than to be hungry." Lu Siyu said as he looked at the food in front of him, feeling like he was facing an enemy.

Song Wen turned to Lu Siyu and asked, "How is your body feeling recently?" Even though they lived together, Song Wen was still afraid that he would conceal military information.

Lu Siyu shook his head: "Maybe the doctor is right, I'm psychologically dependent on painkillers." Recently, under Song Wen's supervision, he took stomach medicine on time, and he hasn't had stomach problems for at least a few days. .

"That's good. I'll take you to prescribe some medicine later when this case is over." After Song Wen finished speaking, he found a boiled egg in his hand like magic, "I know you dislike the food in the cafeteria, so I'll give it to you and the master." I want a little stir-fry."

Lu Siyu reached out to take it, tapped it twice on the table, lowered his head and focused on wrapping the egg shell with his white hands, and then he found that Song Wen was not in a hurry to eat with the chopsticks, and kept looking at the egg shell. He, he couldn't help asking: "Why are you looking at me like that?"

Song Wendao: "I think that the expert surnamed Zhuang is far worse than you when it comes to the analysis of criminal psychology."

Lu Siyu sat up straight: "Don't say that, at least he graduated with a Ph.D. in psychology."

"Isn't there a post about him on the Internet? He said he graduated from a psychology university abroad." Song Wen said, "I have watched some of his past programs, and many of them are inferred from the results. Now this one The case is still under investigation, so he joined in... don't know if it will help in the end."

Lu Siyu said: "His exposition has some truth, but the conclusion derivation is very avant-garde. Thinking about the good, at least it provides us with some other ideas."

Song Wendao: "Professor Zhuang is too normal. I worry that he won't be able to touch the dark psychology of those criminals."

After hearing what he said, Lu Siyu raised his eyes to look at him expressionlessly: "Captain Song, are you saying... am I perverted enough?"

Song Wen realized that he had said something wrong, so he hurriedly pulled back the words, and rubbed Lu Siyu along his hair, "To me, this is a compliment. It means that you are smart and solve cases quickly. You should eat more and turn around." It’s up to you to solve the case.”

Lu Siyu stopped his chopsticks and said, "However, I heard something else today."

Song Wen asked: "What?"

"I think... Zhuang Yi is a little anxious. He seems to be eager to prove himself. He was eager to summarize some details just after he discovered them. This expert is actually quite guilty. He is not sure about his own theory." Lu At this point, Si Yu added an explanation, "In the process of overthrowing, he added a lot of vague words like, probably, maybe, and some analytical theories that ordinary people think are mysterious. When it comes to examples , It seems that he gave a lot of examples, but in fact, if you read it carefully, you will find that many of the cases he mentioned are incomparable with the cases in front of us now."

Song Wen nodded: "I also have some feelings about what you said. How should I put it, what he said is gaudy, and I always feel that some are just talking on paper... It feels completely different from your usual analysis of those cases."

Lu Siyu's reasoning is more practical, and he can feel that he is going deep into the case and bringing himself into the world of the murderer, but this Professor Zhuang seems to be piling up and applying known theories, he is watching the flowers from the other side .

Song Wen changed the subject at this point, "What do you think about this murderer?"

Lu Siyu ate the eggs brought by Song Wen, and felt that he could not cope with his leader without saying a few words, so he thought for a while and said, "I think the murderer may be the honest man that his relatives and neighbors say, he is very strong. Big, a manual worker, might have a job where going out at night won't arouse suspicion."

Song Wen thought for a while and said, "Actually, I'm also very surprised why in many cases, after the perverted murderer is investigated, people who know him will give the impression of being honest and shy."

Lu Siyu took the egg in his slender fingers and took a small bite: "Maybe they equate being silent with honesty. As a perverted killer, the movements in his mind and real actions are enough. gone."

Many perverted killers are not obvious in their lives, and they are often found in the end, and everyone will be surprised.This characteristic is also one of the reasons why it is difficult to find the murderer.

"What about the method of killing?"

"This serial murderer likes to strangle his neck..." Lu Siyu shook his head as he said this, as if he disliked the dullness of eggs, "It's nothing special, it's just because he likes..."

Some people kill with passion, some people kill with revenge, some people kill for money, and this person kills because he likes it, and strangulation can bring him joy and pleasure.

Lu Siyu further explained: "The murderer likes women, likes to let them die, likes to suffocate them. Before death, every part of their body convulsed and trembled, and every pleading made him linger and arouse his interest. Killing is even more interesting. It can make his body and nerves reach the peak, once tasted this taste, he will never forget it again."

Song Wen looked at Lu Siyu, and when he said these words, he licked his lips lightly, his long eyelashes trembled slightly, his voice was calm, his handsome face was indifferent, like a beautiful flower, but it contained deadly Tempting poison.

It is difficult for ordinary people to understand, but this murderer can get the greatest happiness and satisfaction from it, which can stir his nerves more than tens of millions of money, delicious food, and normal relationships between men and women.

Lu Siyu concluded: "Usually, people call this kind of person a pervert."

They are completely different from the killers like Xia Weiwei. Xia Weiwei is intelligent, purposeful, and planned to commit crimes, while they rely more on instinct. The reason for the crime is because they like it, because—— sex.

Because of this originality and uniqueness, they are more difficult to trace, difficult to control, unpredictable and elusive.

Lu Siyu continued: "It's like the cells in everyone's body, when they make mistakes, they will produce cancer cells. Among the tens of thousands of human beings, there are such human beings with genetic errors. If we compare modern society to Programs, they are like error codes that exist in life, they will be confused and painful about the difference between themselves and ordinary people, but they can’t help it, they are born like this.”

Song Wendao: "It feels inevitable that such a person will become a murderer."

"Not necessarily. Many people with strange hobbies will not commit crimes. Education and a good childhood life can reduce the chances of such people committing crimes. A bad growth environment will intensify the birth of perverts. Most people who later embark on the road of crime, They all had unhappy childhoods."

Lu Siyu thought for a while, and then asked Song Wen: "You should know the theory of the triangular stool, right?"

Song Wen nodded. It was a relatively well-known criminal psychology theory: "The triangular stool theory determines three aspects of a person's abnormal psychology: genes, brain damage, and environmental factors. This is second only to the three elements of serial killers: Bedwetting, animal cruelty, arson."

Lu Siyu said: "The person who proposed the triangle stool theory has a criminal gene. If he didn't have a perfect childhood, maybe he would also become a killer. In fact, these two theories are similar, but the angle of analysis is different. , The cause of this kind of perverted murderer can be simply analyzed as external factors and internal factors. Most serial murderers have imperfect childhoods, and they themselves have perverted genes.”

Song Wen was a little helpless: "This is something that can't be helped. When I was young, I didn't understand these things very well, but when I grew up, I found that there are some scumbags. Parents, it is the children who suffer.”

Those who become parents in a hurry without thinking clearly, they themselves are confused, confused, painful, irritable, such people, they will treat their children as their punching bag, as a burden, so indifference And abuse starts at a young age.

Lu Siyu nodded: "What's more frightening is that this kind of harm is continuous. The more children are afraid of something in childhood, the more likely they will repeat the same mistakes. Children whose parents are divorced, when they grow up, are more likely to be divorced. Children whose parents come out of a harmonious family, and children who have been subjected to domestic violence and abuse, will increase the rate of domestic violence and abuse of their own children in the future."

Immature adults will bring poverty and violence to children. They may not realize what terrible influence they have caused, and this terrible influence will be passed on.

Lu Siyu took a sip of the soup and continued: "Let's talk about this murderer, when he kills, his excitement reaches peaks and troughs, and then he will relive that feeling in his mind repeatedly, like Looking at a video he likes very much, as long as he thinks about it, he can feel happy and satisfied. He thought about it repeatedly, until his thinking began to get tired, the details gradually became blurred, and his emotions fell to the bottom, as if he was tired of eating After eating a dish, it becomes dull. At that time, he will commit crimes again, and he needs more intense stimulation."

Having said that, Lu Siyu stuffed the last bit of egg into his mouth, stretched out his pink tongue and licked his fingers: "This murderer has reached the point where he will feel uncomfortable and unable to sleep if he doesn't kill anyone. He's going to do it again soon."

Song Wen thought for a while and asked again: "What about the clothes covering your face? What do you think it means?"

"Just like the stockings that were taken away, it is the murderer's mark, and it is also a habit he had from the beginning. I think...it may have something to do with his childhood experience and his mother." Lu Siyu said.

This is an important totem in matriarchal worship, and it is also special in getting along.

Song Wen turned his head and asked, "Also, what do you think of Zhuang Yi's deduction of the two murderers?"

Lu Siyu lowered his head and pondered for a moment: "The current information is too little to be sure. The murderer may be one person, or two people. Extreme emotional changes are not the only possibility. In fact, I think that It is an inference, but it cannot help us narrow down the scope and find the murderer for the time being."

In other words, Zhuang Yi's theory does not allow them to narrow the scope of investigation and speed up the finding of the murderer. They must find other directions of investigation.

Lu Siyu paused for a moment, slid his slender fingers across the table, and whispered, "I'm thinking about something."

"what?"

Lu Siyu raised his eyes and looked at Song Wen. With the trembling of his eyelashes, the folds on his eyelids folded together: "The first time, the origin of killing."

Was the first victim the first person the killer killed?Did he kill anyone else before that?If the first victim was killed in the first place, what triggered the murderer's sudden killing?And what triggered his evolution?

In fact, the investigation found that many serial killers have had their first case. At that time, they may be unconscious, or they may have witnessed the killing, or they may have killed someone unintentionally, or even their own pets. , in short, all of this has a beginning.

Song Wen continued following his train of thought: "I also pay more attention to the first case, whether it is his first murder or not, the first victim, Li Ling, is very critical."

Human behavior changes start from the most instinctive place. When committing a crime for the first time, the murderer’s purpose is the purest, and the method he adopts is also the most primitive. Turning ideas into practice, such behavior will reveal more information.

Lu Siyu nodded: "There is one more thing I can't figure out. The killing time of the third victim has changed. What changed the murderer's behavior pattern? In the first two cases, they killed someone and went home to sleep, while the third victim , it was like getting up and killing after tossing and turning in bed and not being able to sleep at night. Why did he change like this? Is it because there was a nice ball game that night? A date that he couldn’t miss? gauze..."

Song Wen lowered his head and concentrated for a moment: "Perhaps... There is a possibility that he may not have changed his behavior logic, but we have missed something. For example..."

Lu Siyu nodded, he also thought of a possibility, and said softly, "The escaped prey."

If the woman who died this morning hadn't been the murderer's original prey... He had tried to commit the crime last night, and because of some circumstances that didn't work, he'd become enraged and eager to find new prey to fill his plans.

From late at night until early in the morning, wandering to the streets, and then find your target, tailgating...

Wang Xiaopei may be the unlucky replacement lamb.

Lu Siyu blinked and said, "This situation is only possible."

"I think this is a direction that can be investigated." Song Wen said, ignoring his meal, he picked up his mobile phone and called Fu Linjiang.

"Linjiang, please contact the police center and ask if you have received a call from last night to early this morning. The victim is a woman who was attacked at night. Maybe they just treated it as an ordinary attempted robbery and comforted the victim before going back. Yes. Yes, since there were no fatalities and no major incidents, we did not attach importance to reporting it to our side."

After Fu Linjiang on the opposite side said something, Song Wen nodded with a more serious expression: "Yes... If there is any discovery, it may be a surviving witness."
