Criminal Investigation Notes

The two people still walked back according to the distance they had come. First they took a taxi to the city, and then went to the railway station to get the ticket. The train back was a high-speed train.

The motor car is much cleaner than the old train in the past. Lu Siyu looked at the a little noisy environment and said to Song Wen, "Let’s go to the dining car. I will ask you to drink something. There are tables on the dining car where you can write. At this point, there should not be many people there, so it is convenient to discuss the case."

Sure enough, as he said, it’s not a meal now. Compared with ordinary cars, the dining car is much looser and quieter. Two people occupy a four-person seat. There is a small table in front of him. Lu Siyu gives Song Wen some food. After drinking melon seeds and snacks, I drank the water in the thermos.

Song Wen was a little sleepy at this time. In order to prevent him from falling asleep, he opened the notebook and began to draw. Under the shaking of the train, the control of the pen tip was much more difficult than usual, but it made the lines drawn a little more distracting. As he wanted, not long after, Song Wen drew a girl's face on the paper. It was Lin Wanwan's face. It looked calm and pitiful, but his eyes were unfathomable.

The number of stops for the train is much less than when it first came. The train drove forward, and the scenery outside the window kept changing, gradually from the town to the farmland, and then passed a few caves. Song Wen finished the portrait of the character. Lifting his head, Lu Siyu sat opposite him, opened the record book, and habitually bit his nails while watching.

Song Wen found that Lu Siyu had the habit of biting his fingers when he wanted to concentrate. Now he bit the fingers of his left hand in his mouth and writes and draws on the notebook with his right hand. Song Wen looked carefully, Lu Siyu's pair was clean. On his slender, well-knotted hands, all his nails were bitten even with his fingertips. Under Song Wen’s gaze, Lu Siyu put the notebook on the table and said, “I finally sorted it out. The matter is still inseparable from Lin Wanwan."

"Why?" Hearing these words, Song Wen became interested and leaned forward to look at it. In the notebook, Lu Siyu drew the relationship of the characters, centering on Lin Wanwan, with one dormitory on one side and family on the other.The family made a family tree and marked all the people they currently know.

"Class." Lu Siyu pointed to the picture on the notebook and came to a conclusion.

Song Wen was a little puzzled, Lu Siyu clicked on the map again, "The class of the dormitory, and the class of her family."

Song Wen was even more confused: "There are only a few people in this altogether. How come a class is created?"

"Do you remember that I mentioned the gas lamp effect." Lu Siyu asked him.

Song Wen nodded.

Lu Siyu clicked on the bottom name on both sides of the picture: "If the tortured and manipulated character in the family is the mother, in the dormitory, the tortured may be Guo Wei."

Song Wen looked at the picture drawn by Lu Siyu, which was divided into three levels. On the family side, the first level was Lin Wanwan, the second level was the younger brother, the stepfather, and the third level was the mother.

On the other side of the dormitory, the first level is Lin Wanwan, the second level is Dong Fang, Ma Aijing, and the third level is Guo Hua.

Song Wen came to understand a little bit: "You mean, these people have classes, and Lin Wanwan is the one who controls?"

Song Wen still remembers that when everyone had a disagreement on whether Lin Wanwan was a suspect, Lu Siyu said that Lin Wanwan was a manipulative personality.He has read some psychology courses and knows better about controlling personality than others. Many people with controlling personality are not all strong, arrogant, impulsive, but may be innocent, innocent, or even innocent. Modest, but their hearts are arrogant, paranoid, and even jealous.For such people, the pure appearance is their disguise. They cleverly hide their intentions under friendly popularity, like wolves in sheep's clothing in the crowd.

Lu Siyu explained: "Lin Wanwan is her mother's proudest and most trusted daughter. She is Guo Wei's closest friend. Such a relationship allows her to grasp their weaknesses and better deceive them. Feeling that, let the victim fall into a passive relationship."

Even now, they couldn't ask Wang Wenyan about her complaint about her daughter.But this daughter is undoubtedly the key person who made her status in the family so far.The same is true for Guo Wei. Dong Fang’s clothes cannot disappear out of thin air. Why did Guo Wei’s untouched notebook get wet? There are some clues in these things.

Class is the inevitable product of social development. As long as there are people, classes will be produced.Everyone is in a different position, differentiated into different levels, and each has his own position.

In the dormitory and family, Lin Wanwan is a person with vested interests, standing at the top of the pyramid.

At home, her mother is responsive to her and keeps everything good to her. Her younger brother is still very weak, and her stepfather is not at home all year round. She is the hope and pride of the family.In the dormitory, whether Guo Wei serves her dinner or picks her up in the rain, these are not only the performance of a good friend, but also the performance of her being controlled by her enslavement.However, Guo Wei had the idea of ​​moving out of the dormitory several times, but he gave up the idea several times, which was obviously related to Lin Wanwan.

Song Wen frowned: "Lin Wanwan is just a twenty-year-old girl. How did this relationship form?" Intuition told him that Lu Siyu's statement was correct, but he didn't believe it. The teacher has learned to this level.

"The formation of each person's personality is inseparable from her growth environment and growth experience. Lin Wanwan is the same. The formation of her personality is related to her family and the things she has experienced since childhood. It is related to Wang Wenyan's During the conversation, we can learn that Lin Wanwan grew up in the family of her grandparents who preferred sons to daughters. The tutoring is very strict, and the family has a strict hierarchy. Each family member has their own responsibilities. I am in Lin Wanwan's body and her family. , I found several important information. The first one is scars, the second one is chocolate, and the third one is a doll."

While speaking, Lu Siyu drew brackets and wrote these three key words, and then continued: "The environment she is in is harsh and depressing. She is coercive and lured, both soft and hard, hit a stick, give a candy, Her scars are the punishment for wrongdoing, and her chocolates are the rewards. She was taught in such an environment, like a slave who was raised, and naturally incorporated these into her world."

"The young Lin Wanwan was like a piece of white paper. The first thing she suffered was endless suffering, beatings and scolding from her own father, and harsh rebuke from her grandmother and grandfather, which hurt her young mind. Under such circumstances, she was suddenly hurt. Candy is the best comfort. She is like a Stockholm hostage. She is gradually attracted by the gentleness hidden under domestic violence. While being abused, she is also learning."

Having said this, Lu Siyu paused slightly and looked at Song Wen: "The sugar must be delicious and the whip must be accurate. If this happens, the prey will be firmly fixed by his side."

This is the most important thing Lin Wanwan learned in that family, and it is also the thing that affects her life.Next, Lu Siyu continued to draw a timeline: "After she escaped from that environment, she has reached ten years old. At this time, she was replaced by the mother's doting and the stepfather's indifference. Lin Wanwan is a smart girl, she Apply the methods learned in the last family and use these instinctively in her life."

Later, Lu Siyu drew a straight line between Lin Wanwan’s name and Wang Wenyan: “She didn’t love her mother, and even regarded her as the source of her painful childhood. In the second home, she regarded herself Wang Wenyan, the mother of Wang Wenyan, regarded as the object of enslavement. While approaching her and forming emotional bondage with her, she denied her, crushed her will, and tortured the controlled person mentally. In this torture, the other party treated her Will become more and more dependent, and eventually coexist."

"Later she came to school and set Guo Xu to be the target of this manipulation. In school, Lin Wanwan kept instilling some ideas on Guo Xu: Although your family background is not good, your character is withdrawn and weak, but only I am Hello, I am your best friend. You must not let me down and betray me. As a good friend, it is normal for you to do something for me. Only me who treats you well, and your world is only me."

These are the things that are often said between little girls. Girls who have just entered college, have left the family and are not deeply involved in the world, and are easily confused by such friendship.But now that these have been analyzed by Lu Siyu, it makes Song Wen chill behind his back.

Lu Siyu concluded: "This is a twisted and perverted girlfriend relationship." He paused, "It's more like a slave-master relationship."

At first, Lin Wanwan gained Guo Wei's trust, and then she continued to question her, deny her, isolate her, and make her lose herself more and more, and rely more on this only friend.At that time, Guo Wei became obedient to her.This process is simple to say, but in fact, it has gone through several months or even years, and it has evolved bit by bit.

Under this analysis, Lin Wanwan's portrait became much clearer, and the relationship between Lin Wanwan and Guo Xu also became clearer.She no longer looks innocent, and is also closely related to this bedroom.

"What about the baby?" Song Wen noticed that Lu Siyu mentioned three things, but only said two things during the analysis.

Lu Siyu blinked his eyes and looked at him: "She has grown up, and she has come into contact with society and people, so she doesn't need those dolls."

Yes, her family members are her dolls, her classmates are her dolls, and her colleagues are her dolls. Even their investigating policemen are no different from those dolls in her eyes. It is her way of doing things, unconsciously selecting targets in the crowd for her use.Her showing of weakness, her pity, are her weapons.

All the signs that can be seen now show that Lin Wanwan doesn’t care about Guo Wei very much, or that she doesn’t care about anyone except herself. She keeps binding Guo Wei and turns her into her hand. Baby, and the string is tightened.

She likes this kind of game between people.

Although Song Wen didn't understand the perverted heart, he was a smart person after all. He quickly figured out the plot. This girl was cunning and smart.When they met for the first time, they saw her lie about the source of the poison, and then she changed her rhetoric.She used to pretend to jump off the building in order to win the sympathy of others.Such a seemingly vulnerable girl is naturally in a disadvantaged position. She is also being selected by the police. For example, she can't help but sympathizes with her, and the old Jia who is seduced by her... thus affects whether they treat her. Judgment of the suspect.

After trying to understand this, Song Wen said to Lu Si: "I understand that she will look for people who are suitable for control in the crowd, but what is the relationship between these and class? Or how does class come into being?"

When the train arrived here, a cloud suddenly passed, and the shards of sunlight cast from the gaps in the clouds, with a little golden color, hitting Lu Siyu’s distinct fingers, shining like a pale hand. A beautiful artwork, he clenched his pen and drew a few arrows on the picture, "Everyone is in the game. She builds relationships to achieve the purpose of manipulating and confusing others."

After all, it is easy to control a person, but it is not so easy to control a group.And we must be more careful about the manipulation of groups.

Lu Siyu thought for a moment, wondering how he could explain to Song Wen clearly: "I'll tell you a fable, have you heard of the wet monkey experiment?"

Song Wen was a little bit impressed by this word, "You are talking about the experiment, right? Put five monkeys in a cage, and then put bananas on the top surface. As long as there are monkeys picking bananas, they will be exposed to water. When monkeys pick bananas, they will be beaten by other monkeys. Later, when new monkeys were put in, the monkeys would still operate like this. Scientists replaced the top water gun, and no monkey dared to pick bananas anymore."

Lu Siyu turned the pen in his hand and said: "This experiment is from a business book, so whether the experiment has been carried out is inconclusive. It can be regarded as a story. What I want to say is a derivative version of this story."

"It's still a cage, four monkeys, monkey ABCD respectively. This pipe is relatively small, and only monkeys who go to get bananas will get drenched. The strongest monkey is Monkey A. He wants to eat bananas, but he doesn't want to be caught. He got wet, so he asked the weakest monkey D to get the banana. Monkey D was soaked in water, and monkey A ate the banana. Monkeys B and C envied that monkey A ate the banana, but they were better than the wet monkey D. A lot of happiness again."

"At this time, a strange psychology was born. Monkey BC faced Monkey A. They felt humble. When faced with Monkey D, they felt superior. Therefore, the four monkeys had three classes, and the class was the monkey. Produced in the group."

The situation in reality is definitely more complicated than this story, but in this way, the story is simple and easy to understand. Song Wen sorted out his thoughts, "You mean, at home, the mother is a weak monkey D, in the dormitory , Guo Wei is the weak monkey D. And Lin Wanwan is the monkey A?"

Lu Siyu nodded: "Even sometimes, that weak monkey D is a gift she gave to monkeys B and C. Other people will follow the oppressor's behavior and start to oppress them. Just like his brother. Will scold her mother, Dong Fang and Ma Aijing will punish Guo Yu. Lin Wanwan is constantly adjusting various relationships, intentionally and unintentionally. The interpersonal relationship in the dormitory itself has contradictions and weaknesses. You can make a fuss about its own contradictions."

Speaking of this, Lu Siyu habitually licked his lips. From Song Wen’s perspective, his eyelashes are distinct, but his eyes are unfathomable: “Through punishment and reward. The beginning may be just a small game. It’s because Guo Wei was not in the dormitory, they were a little bit malicious, but the violence will gradually escalate. In this way, in the dormitory relationship, Lin Wanwan became the top of the class, in the dormitory, she spent Dong Fang’s Qian, with the help of Ma Aijing’s relationship to make the thesis score high, asked Guo Wei to serve her tea and wash clothes, she even knows her mobile phone password, so her mobile phone is so clean, and when dialing 120, she took it easily. I lost Guo Wei’s mobile phone, because that mobile phone is usually used by her."

Seeing that Song Wen did not interrupt, Lu Siyu continued, his voice low and seductive, enough to confuse people: "The poison was really brought by Guo Wei, and the chocolate was also bought by her. This is probably what Lin Wanwan dares. Let’s interrogate Guo Xu’s reasons. Either Guo Xu was in a state of being coerced, or he was poisoned with Lin Wanwan’s encouragement, or Guo Xu could not believe his own memory, nor did he have the courage to identify her. best friend."

Lu Siyu speaks a lot today. When caught in this kind of reasoning and logic, he is like a child who has made a difficult problem and wants to share his achievements with others. This time, he is no longer hiding in the dark, but sharp. Exposed.Song Wen looked at Lu Siyu in front of him. At this time, he was no longer as dull, soft and cute as before, harmless to humans and animals.There was excitement on his handsome and pale face, cold and ruthless, rational and wise, making him dangerous and charming.

These things are abnormal, unimaginable but completely reasonable. Once you accept this logic, many things in the case can make sense.Song Wen felt that he finally sorted out the case, as if to remove the refraction mirrors in the kaleidoscope, so that the relationship behind it was revealed.

The truth that had been haunting him finally appeared before him, but Song Wen was not happy at all. He rubbed his eyebrows: "I understand your logic, but this situation is still based on assumptions. Psychological control listens. It's too mysterious. We can't expect to rely on these to convince the judge or even the situation. I guess it will be difficult to convince Lao Jia, and some theoretical basis is still needed.

Lu Siyu said: "The core of this case is still poisoning. With these so-called theoretical knowledge, I am analyzing the logic behind the case and the relationship between the characters. But this kind of manipulation is completely feasible." He thought about it and said, "This is the case. Cases are not common in China, but there have been a few cases in Japan. Among them, the more famous ones are the murder case in Kitakyushu."

Song Wen thought about it for a while, "Is it the case in which a couple imprisoned and killed seven people in the 1990s?" He had read some related materials, and now it still makes my scalp numb in retrospect.

Lu Siyu corrected: "It's not that they killed, but that the victims killed each other." Then he sat up straight, "but this case is just similar, because he used electric shocks when manipulating people. It is not purely using psychological manipulation. I just use this example to illustrate that if a person is manipulated by other people, even relatives can face each other with swords."

Song Wen knew about this case in the past, but every time it sounds, it still feels incredible.The education he has received since childhood and his growth experience made him feel that such things are incredible, but these are real sins in the world.

Lu Siyu thought for a while and added: “There is also a Hyogo serial murder case in which the suspect is Miyoko Kakuda. The old lady is known as a mental killer and mainly manipulates and kills through brainwashing. She has rushed to violence, The three factors of sex and psychology have turned the victim’s family into a fighting arena. In the past few years, at least seven people in Japan were killed because of her, and she was not arrested until 2012. Later, with her suicide, many The details and the truth are unknown."

After talking about the two cases, Lu Siyu returned to this case: "However, these are much more serious than the case before us. At least I think that Lin Wanwan has not developed to the point where he completely manipulates others to kill. Therefore, in the end, Guo Hua ran out of the dormitory and called for help."

Song Wen asked, "Then what do you think Lin Wanwan's motive for killing? What is it?"

Lu Siyu stretched out two fingers, "The master wants to kill the slave for two reasons. The first is that he doesn't need the slave, and the second is that the slave is out of control and wants to leave him."

Seeing that Song Wen was a little puzzled, Lu Siyu began to explain in detail: "In the previous questioning, I asked Yaomao related questions. Once I replaced'Guowei' with'you', she did not refute me. And According to our investigation, Lin Wanwan is more like the master of all this. Guo Wei's purpose is to make cats no longer noisy, and she is not only using cats to satisfy her desires, but also a murder simulation. Practice. I think that Lin Wanwan’s nature inherently contains the cruel side of killing. In this society, there are some people who use killing to solve problems for reasons that ordinary people cannot understand."

Song Wen nodded when he heard this. In the past few years of criminal police work, he has encountered a lot of abnormalities: "I understand what you mean, most people in society are not such people, but we can't Deny the existence of this kind of alien."

Lu Siyu lowered his head to look at the relationship diagram of the characters in front of him, whispering with his fingers, and said his guess: "Lin Wanwan came to the school from home, and soon discovered that the dormitory is a place that fascinates her even more. The control is constantly upgraded in the dormitory, where she can live more freely than at home. At this time, she feels that she doesn’t need her family anymore, so she tries to kill her parents and younger brother, she is tired of those People, she thinks they are useless, despise them, she wants to get rid of her native family."

Lu Siyu paused and continued: "As for killing the classmates in the dormitory, it was because she discovered the gap between her family and other people's families. This is a kind of strong jealousy. If it is normal, then it is just jealous. Because in the dormitory where she built the relationship, she can find balance and find comfort in other aspects. But once graduation, this balance will be broken. Those people will get rid of her control, which s
is the things she cannot tolerate." At this point, he raised his head and asked Song Wen, "Did you find out that Lin Wanwan did not make any preparations for graduation."

Song Wen thought for a while, lowered her head and thought: "Dong Fang's family has found a job for her. Ma Aijing is ready to go abroad, and even Guo Wei has bought a new mobile phone and is ready to put into a new life, while Lin Wanwan, in all our searches, she hasn't prepared a graduation resume." In the next semester of the senior year, all the students were eager to enter the society, but Lin Wanwan did not want to come out.

If Lin Wanwan is really the murderer, the first gas incident may be her attempt. This time, her behavior has been upgraded, cautious, careful, and calmer. From the planning to the final execution, there may even be several Months, every time, their yearning for life after graduation stimulated her.

So, she was smart and planned everything. Only people like her can survive and remove suspicion. Those who are regarded as slaves by her will never escape her control and will be kept by her forever. here……

Lu Siyu nodded gently and leaned his body on the back of the chair. He held up his thermos cup and drank the water in it, trying to bring himself into Lin Wanwan’s psychology: “Just think that these people will be separated from her. Control, she will go crazy."

Suddenly, the two men fell silent. They sat face to face on the train. The train was swaying, and the sound of rubbing against the railroad tracks was heard from time to time.

As a policeman, Song Wen often reflected on why he didn't see far enough and couldn't insight into the whole truth, but whenever they approached the detection of the case, he gave birth to such a kind of fear from the bottom of his heart. It turned out that human hearts can grow like this.

He looked up and saw that there were people around him, men and women, old and young. Everyone had a beating heart and a working brain. They were playing with mobile phones and they were talking and laughing. This is the person he can't see through. Complex people.

Finally, his eyes fell on Lu Siyu, what he saw in his eyes was different from what he saw, and what he felt was different from him.He is smart, keen, and meticulous.

On weekdays, Lu Siyu has all kinds of disguise on his body. It seems that he is the real him now. He is sharp and evil.He could feel the excitement when Lu Siyu talked about those criminal acts.He remembered the theory of the criminal psychology teacher when he was in the police academy. Only by fully understanding the criminal, empathizing, and possessing the criminal's thinking, can he correctly analyze criminal behavior and portray the criminal.

A lake and mountains flashed outside the train window, reflecting on Lu Siyu’s face. His hand with the pen suddenly paused, and he seemed to realize that in his reasoning just now, many perspectives had not been converted. People’s logical thinking and way of thinking, The habit of speaking, like a fingerprint, has its own unique ways, even if the disguise is good, these ways will still be revealed unconsciously.

Song Wen didn't pursue it too much, and instead asked him: "The truth is that there is nothing wrong, but there is no evidence in the current case, so we need a complete chain of evidence... We still need some direct evidence."

Lu Siyu thought for a moment, picked up the notebook, and wrote the word "chocolate" on it.

The delicious candy becomes a deadly poison, and everything starts and ends with it.

Lu Siyu raised his head and looked at Song Wen: "I have a bold idea. If my reasoning is not wrong, I think there may be evidence to prove that it is her." Then he paused and said, "But Team Song, I hope you can promise me one thing first."

Song Wen raised his eyebrows: "What's the matter?"
