Criminal Investigation Notes

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

Song Wen first took Lu Siyu to the cafeteria.In the past few days, Li Luanfang caught them by surprise, and finally sent the old lady away. Lu Siyu was rarely lazy and did not cook.

Lu Siyu was not too cold with the dishes in the city bureau’s cafeteria. Gu Bureau procrastinated for time. He didn't want to order takeaway, so he came over and ordered two dishes.

The cafeteria in the team is full of big pot dishes, and the master has a kind of ability, no matter what ingredients are used for stewing, boiling, and frying, all the dishes are made with the same taste.This canteen is generally ventilated. Every time a meal is served, the canteen is filled with this unique food fragrance, which makes people half full when they smell it.

A few dishes were placed on the plate, Lu Siyu picked and picked like a bird, and ate the bean sprouts one by one.

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

"In the cafeteria...what else can be delicious, it's better than being hungry." Lu Siyu spoke and looked at the food in front of him, feeling like an enemy.

Song Wen turned his head and asked Lu Siyu: "How do you feel about your body these days?" Although living together, Song Wen was afraid that he would conceal military information.

Lu Siyu shook his head: "Maybe the doctor is right. I have a heavy psychological dependence on painkillers." He recently took stomach medicine on time under Song Wen's supervision. He has not had stomach problems for at least a few days. .

"That's good. When the case is over, I'll take you to prescribe some medicine." After Song Wen finished speaking, he magically touched out a boiled egg in his hand, "I know you dislike the food in the cafeteria and give it to you and the master. Want to stir."

Lu Siyu stretched out his hand to take it, knocked on the table twice, bowed his head and wrapped the egg shell intently with his white hands. Then he found that Song Wen was not in a hurry to eat with chopsticks, his eyes kept looking He, he couldn't help asking: "Why look at me like this?"

Song Wendao: "I think the expert named Zhuang is far worse than you when it comes to analyzing the psychology of criminals."

Lu Siyu sat up straight and said, "Don't say that, someone graduated with a PhD in psychology anyway."

"Isn't there a piece of his peeling stickers on the Internet? It is said that he graduated from Pheasant University in psychology abroad." Song Wen said, "I have watched some of his past shows, and many of them are inferred from the results. The case is still under investigation, so he joined in... I don't know if it will help in the end."

Lu Siyu said: "His argument has some truth, but the conclusion is very avant-garde. If you think about it, at least it provides us with some other ideas."

Song Wendao: "Professor Zhuang is too normal. I am worried that he will not be able to touch the dark psychology of those criminals."

After listening to what he said, Lu Siyu raised his eyes blankly and looked at him: "Team Song, are you saying... Am I abnormal enough?"

Song Wen realized that he had said something wrong, and hurriedly moved the head of the conversation back, and followed Mao Lu's words, "With me, this is a compliment. It means that you are smart and solve the case quickly. Eat more and look back. It depends on 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, as if eager to prove himself, he just found out some details, and he rushed to summarize it. This expert is actually quite guilty. He is not sure about his theory either." Si Yu said this and added an explanation, "During the overturning process, he added a lot of vague words, like, probably, possible, and other vague words, as well as some ordinary people think mysterious analysis theories, when talking about examples. It seems to have cited a lot of examples, but when you read it carefully, you will find that many of the cases he said are incomparable with the cases before our eyes."

Song Wen nodded: "I also have some feelings about what you said, how can I say it, he said it in a fancy way, I always feel that some of it is on paper... it feels completely different from your usual analysis of the case."

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 criminals, but this Professor Zhuang is like piling up and inserting known theories, he is watching flowers from the other side. .

Song Wen changed the subject when he said, "What do you think of this murderer?"

Lu Siyu ate the egg that Song Wen brought, and felt that he could not deal with his leader without saying a few words. He thought about it and said, "I think the murderer may be the honest person mentioned by relatives and neighbors. He has great strength. Big, a manual worker, and may have a job that will not arouse suspicion when going out at night."

Song Wen thought for a while and said: "In fact, I am also very surprised, why in many cases, after the perverted murderer is investigated, people who know him will get the impression of being honest and shy."

Lu Siyu took the egg in his slender fingers and took a small bite: "Perhaps they equate taciturnity with honesty. As a perverted killer, the movement in the brain and the real action are enough. Up."

Many perverted killers do not show any signs of leakage in their lives, and they are often surprised when they find their heads in the end.Such characteristics are also one of the reasons why it is difficult for a murderer to find.

"What about the method of killing?"

"This serial murderer likes to strangle his neck..." When Lu Siyu said this, he shook his head, seemingly disgusted with eggs, "Nothing special, just because he likes..."

Someone kills with passion, some kills with revenge, some kills with murder, and this person kills because he likes it. Strangling kills can bring him pleasure and pleasure.

Lu Siyu further explained: "The murderer likes women, he likes to let them die, he likes to suffocate them. Before death, every point of their body spasm and tremble, every plea made him linger and arouse interest. More killing It can bring his body and nerves to the highest peak, as long as he tastes this taste once, he will never forget it again."

Song Wen looked at Lu Siyu. When he said these words, he lightly licked his lips, his long eyelashes trembled slightly, his voice was calm, and the expression on Junxiu's face was indifferent, like a beautiful flower, but it was fatal and fatal. Seductive poison.

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

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

They are completely different from murderers like Xia Weiguchi. Xia Weiguchi is wise, purposeful, and planned to commit crimes, while they rely more on instinct. The reason for the crime is because of like, because - Sex.

Because of this primitiveness 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 that produce cancer cells when they make mistakes. Among tens of thousands of human beings, there are humans with such genetic errors. If modern society is compared to Programs, they are like error codes in life. They are 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 for such a person to become a murderer."

"Not necessarily. Many people with strange hobbies will not commit crimes. Education and a good childhood life can reduce the chance of such people committing crimes. The poor growth environment will intensify the birth of abnormalities. Most people who later embark on the path of crime, All have unhappy childhoods."

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

Song Wen nodded. That is the more famous theory of criminal psychology: "The triangle stool theory determines three aspects of a person's abnormal psychology: genes, brain damage, and environmental factors. This article is second only to the three elements of serial killers: Bedwetting, cruelty to animals, arson."

Lu Siyu said: "The proponent of the triangle stool theory has the gene of crime. If he does not have a perfect childhood, maybe he will become a killer. In fact, the two theories are similar, but the angle of analysis is different. The cause of this perverted murderer can be simply analyzed as external 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 a child, I didn't understand these things, but when I grew up, I found that there were some scumbags. They became scumbags before my life was fully understood. Parents, it is the children who suffer."

Those who become parents in a hurry without thinking clearly, they themselves are confused, confused, painful, and irritable. Such people will treat their children as their punching bag and as a burden, so they are indifferent. Abuse and abuse begin at a young age.

Lu Siyu nodded: "What's more terrifying is that this kind of injury is continuous. The more a child is afraid of something in childhood, sometimes the more he will repeat the same mistakes. Children whose parents are divorced are more likely to be divorced when they grow up. Children born from a harmonious parental family, and children who are subjected to domestic violence and abuse, will have an increased 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 the 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 go back to this murderer. When he killed someone, his excitement reached a peak and trough. Later, he would relive that feeling repeatedly in his mind, like Looking at a video that he likes very much, as long as he thinks about it, he can feel happy and satisfied. He kept thinking and thinking until his thinking began to get tired and the details gradually blurred, and his emotions fell to the bottom of the wave, as if tired 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 finger: "This murderer has reached the point where he doesn't kill, he is uncomfortable and unable to sleep. His mind is full of In this matter, he will commit the crime again soon."

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

"Like the silk stockings taken away, it is a sign of the murderer and a habit he had in the first place. I think... it may be related to his childhood experience and his mother." Lu Siyu said.

This is an important totem in matrilineal worship, and it is also in getting along with it, and it has special features.

Song Wen asked, "Also, what do you think of Zhuang Yi's 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’s an inference, but it can’t help us narrow down and find the murderer for the time being.”

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

Lu Siyu paused, stroked 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 light tremor of his eyelashes, the folds on his eyelids were gently folded together: "The first time, the origin of the killing."

Was the first victim the first to be killed by the murderer?Before that, had he killed anyone else?If the first victim was killed in the first place, what caused the murderer to kill suddenly?What triggered his evolution?

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

Song Wen continued along his line of thought: "I also paid more attention to the first case. Whether it was his first murder or not, the first victim, Li Ling, is very critical."

The change of human behavior starts from the most instinctive point. When committing a crime for the first time, the murderer’s purpose is the purest and the method adopted is the most primitive. He will not have so many ideas and rules. Thinking is transformed into practice, such behavior will reveal more information.

Lu Siyu nodded: "There is one more thing I can't figure out. The time of the third victim's murder has changed. What changed the murderer's behavior? The first two cases involved killing individuals and going home to sleep. , It’s like he got up and killed after tossing and turning in bed at night after being awake at night. Why did he change like this? Was it because of a nice game that night? A date that I couldn’t miss? Or because of what? The blood was left on the scene. The gauze..."

Song Wen bowed his head and concentrated for a moment: "Perhaps... there is a possibility. He may not change his behavior logic, but we missed something. For example..."

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

If the woman who died this morning was not the original prey of the murderer...he tried to commit a crime last night, and because some circumstances failed, he would become angry and eager to find new prey to fill his plan.

From late night to early morning, wandering to the street, then find one's goal, and go to the end...

Wang Xiaopei may be the hapless lamb for substitution.

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

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

"Linjiang, you can contact the police receiving center and ask if there has been an alarm from last night to early this morning. The victim was a woman and was attacked at night. Maybe they just treated the victim as an ordinary attempted robbery. They comforted the victim and went back. Yes. Since there were no lives and no major incidents, we didn’t pay attention to reporting to us.”

What Fu Linjiang on the other side said, Song Wen nodded more solemnly: "Yes...If there is any discovery, it may be a surviving witness."
