Criminal Investigation Notes

Two people are still in accordance with the time of the journey back, first took a taxi to the city, and then went to the railway station to pick up the ticket, the bus back is the motor train, the time of boarding is not dangerous.

The old train was much cleaner than before. Lu Si Yu looked at the noisy environment and said to Song Wen, "let's go to the dining car. I'll buy you something to drink. There is a table over the dining car where you can write. And at this point, there should be not many people there, so it is convenient to discuss the case. "

As he said, it's not a meal now. Compared with the ordinary carriage, the dining car is much more relaxed and quiet. Two people occupy a seat of four. There is a small table in front of him. Lu Siyu orders drinks, melon seeds and snacks for Song Wen, and drinks the water in the thermos cup himself.

Song Wen was a little sleepy at this time. In order not to let himself fall asleep, he opened his book and began to draw. Under the shaking of the train, the control of the nib was much more difficult than usual, but it made the lines drawn more distracted. Soon, Song Wen drew a girl's face on the paper, which was Lin wanwan's face. It looked indifferent and pitiful, but his eyes were unfathomable.

The number of stops for the train is much less than before. As the train moves forward, the scenery outside the window changes constantly. From the town to the farmland, and then through several caves, Song Wen draws the portrait of the figure. Looking up, Lu Siyu sits opposite him, opens the record book, and habitually bites his nails while looking at it.

Song Wen found that Lu Siyu used to bite his fingers when he usually wanted to concentrate. Now he bit his left finger in his mouth, and his right hand wrote and drew on the book. Song Wen looked carefully at Lu Siyu's clean, slender, bony hands, and all his nails were even with his fingers. Under the gaze of Song Wen, Lu Siyu put the book on the table "I finally made it clear that Lin wanwan had something to do with the poisoning."

"What?" Hearing this, Song Wen became interested and leaned forward to look. In his book, Lu Siyu painted the relationship between the characters, centering on Lin wanwan, with one side as the dormitory and the other as the family. A family tree has been made on the side of the family to mark all the people they know so far.

"Class." Lushi language refers to the figure in the reference book and draws a conclusion.

Song Wen does not understand its meaning, and Lu Si Yu points out on the map, "the class of the dormitory, and the class of her family."

Song Wen was even more confused when he heard this: "there are only a few people in all. How did class come into being?"

"Do you remember I mentioned the gas lamp effect?" Lu Si asked him.

Song Wen nods.

Lu Si Yu points the names at the bottom of both sides of the picture: "if in the family, the role who suffers from torture and manipulation is the mother, in the dormitory, the tortured person may be Guo Zhen."

From the perspective of Song Wen, his eyes are clear, but his eyes are unfathomable: "through punishment and reward. It may be just a small game at the beginning. It is a little bit of malice when Guo Zhen is not in the dormitory, but the violence will gradually escalate. In this way, in the dormitory relationship, Lin wanwan has become the top class. In the dormitory, she spent Dong Fang's money to get a high score in her thesis with the help of Ma Aijing. She even knew her mobile phone password. Therefore, her mobile phone was so clean. When she dialed 120, she took Guo's mobile phone conveniently because it was Ping It's used by her

Seeing that Song Wen didn't interrupt, Lu Siyu continued, in a low and attractive voice, which was enough to bewitch people: "the poison was really brought by Guo Ji, and the chocolate was also bought by her. This is probably why Lin wanwan dare us to interrogate Guo Juan. Either Guo Gu is under duress, or he poisons under the encouragement of Lin wanwan, or Guo Jian is fundamental I can't believe my memory, and I don't have the courage to identify her best friend

Lu Si Yu speaks a lot today. When he falls into this kind of reasoning and logic, he looks 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 is showing his edge. Song Wen looks at Lu Si Yu in front of him. At this time, he is no longer as dull, soft and cute as he used to be. His handsome and pale face showed a kind of excitement, cold and merciless, rational and wise, which made him dangerous and charming.

These things are extraordinary, bizarre and perfectly reasonable. Once we accept this logic, many things in the case can make sense. Song Wen felt that he had finally straightened out the case, as if he had removed the mirrors from the kaleidoscope and made the relationship behind them present in front of him.

However, Song Wen was not happy at all. He rubbed his eyebrows and said, "I understand your logic, but this situation is still based on hypothesis. Psychological manipulation sounds too abstruse. We can't rely on these arguments to convince the judge or even take care of the Bureau. I think it's difficult to persuade Lao Jia, and we still need some theoretical basis. "

Lu Si Yu said: "the core of this case is poison killing. I am analyzing the logic and the relationship between the characters behind the case. But this kind of manipulation is completely feasible. " He thought about it and said, "such cases are not common in China, but there have been several cases in Japan. One of the more famous cases is the murder case in beikyushu. "Song Wen recalled, "was it the case in the 1990s when a couple imprisoned and killed seven people?" He has read some relevant materials, but in retrospect, it still makes people's scalp numb.

Lu Si Yu corrected: "it is not that they kill, but let the victims kill each other." Then he sat up straight, "but this case is just similar, because he used electric shock when manipulating people, not just using psychological manipulation. I just use this example to illustrate that if people are manipulated by others, even their relatives can fight each other with swords. "

Song Wen has known about this case in the past, but every time it sounds strange. His education from childhood to adulthood and his growth experience make him feel that such things are incredible, but these are the real evils in the world.

Lu Siyu thought for a moment and added: "there are similar cases in which the suspect is Miyoko Okada, and the old lady is known as a psychic killer. She mainly manipulates and kills people by brainwashing. She grasped the three factors of violence, sex and psychology to turn the victim's family into a arena. Over the years, at least seven people were killed in Japan because of her, and she was not arrested until 2012. Later, with her suicide, many details and the truth were not known. "

After finishing the two cases, Lu Siyu returned to the case: "however, these cases are much more serious than the cases in front of us. At least, I think that Lin wanwan has not developed to the point of completely controlling others to kill people. Therefore, at last, Guo fan ran out of the dormitory and called for help."

Song Wen asked: "what do you think is Lin wanwan's motive for killing people? What is it? "

Lu Si Yu held out two fingers, "the master wants to kill the slave for two reasons. First, he doesn't need slaves. Second, slaves are out of control and want to leave him. "

Looking at Song Wen's confusion, Lu Siyu began to explain in detail: "in the previous inquiry, I asked about the drug cat. Once I replaced" Guo Zhen "with" you ", and she did not refute me. What's more, according to our investigation, Lin wanwan is more like the leader of all this. Guo's purpose is to stop the cat from making noise. She is not only using killing cats to satisfy her desire, but also carrying out simulation practice of murder. I think there is a cruel side to killing in Lin wanwan's nature. In this society, there are some people who will use killing to solve problems for reasons that ordinary people can't understand. "

Song Wen nodded his head when he heard this. In recent years of criminal police work, he encountered many abnormal people: "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 and looked at the figure in front of him. His fingers whirled slightly and said his speculation: "Lin wanwan came to the school from home, and soon found that the dormitory was a more fascinating place for her. Her control was constantly upgraded in the dormitory, where she could live a more free life than at home. At this time, she felt that she didn't need her family, so she tried to kill her parents and brother. She was tired of those people. She thought they were useless and despised them. She wanted to get rid of her original family

Lu Siyu stopped for a moment and continued: "as for the students who killed the dormitory, it is because she found the gap between her own family and other people's families. This is a kind of strong jealousy. If it is normal, then it is just jealousy. Because in the dormitory where she has built a relationship, she can find balance and find comfort from other aspects. But once you graduate, that balance is broken. Those people are going to get out of her control, which she can't stand Speaking of this, he raised his head and asked Song Wen, "have you found that Lin wanwan has not made any preparation for graduation?"

Song Wen thought for a while, bowed his head and pondered: "Dong Fang's family has found her a good job. Ma Aijing is ready to go abroad. Even Guo Jian has bought a new mobile phone and is ready to enter a new life. But Lin wanwan, in all our searches, we haven't even prepared a graduation resume. " In the next semester of senior year, all the students are eager to enter the society, but Lin wanwan doesn't want to come out.

If Lin wanwan was really the murderer, the first gas incident might have been her attempt. This time, her behavior was upgraded, cautious, careful and calm. From planning to the final implementation, even for several months, every time, their yearning for life after graduation stimulated her.

So, smart she planned everything. Only people like her can survive and get rid of suspicion. Those who are regarded as slaves by her will never escape from her control and will be left here forever

Lu Siyu nodded gently and leaned his body on the back of the chair. He held up his thermos cup and drank the water inside, trying to bring himself into Lin wanwan's mind: "as long as she thinks that these people will be out of her control, she will go mad."

Two people suddenly and coincidentally silence, they two people face to face sitting on the train, the train swaying, from time to time came the sound of friction with the track.

As a police officer, Song Wen often reflects on why he does not see far enough and can not see the whole truth. However, whenever they are close to solving a case, he has such a fear from the bottom of his heart that the human heart can grow like this.He looked up, surrounded by people, men and women, old and young, everyone has a beating heart, running brain, they play mobile phones, they talk and laugh, this is he can not see through, the most complex person.

Finally, his eyes fell on Lu Si Yu. What he saw in his eyes was different from what he saw and what he felt was different from him. He's smart, sharp and meticulous.

On weekdays, Lushi language has all kinds of camouflage on his body. It seems that he is the real one now, with sharp edges and fierce evil. He could feel the excitement of the Lushi speaking of those crimes. He recalled the theory of the criminal psychology teacher when he was in the police academy. Only when he fully understood the criminal, had resonance, and had the thinking like the criminal, could he correctly analyze the criminal behavior and portray the criminal.

A flash of lake and mountain scenery flashed through the train window, reflecting on Lu Si Yu's face. He suddenly stopped with his pen hand. He seemed to realize that in his reasoning just now, many perspectives had not been changed. People's logical thinking, thinking mode and speaking habits were like fingerprints. They had their own unique ways. Even if they were disguised well, they would still be in use It's coming out between you and me.

Song Wen didn't investigate him too much. Instead, he asked him, "the truth is that there is nothing wrong with this, but there is no one to testify in the current case, so we need a complete chain of evidence We also need some direct evidence. "

Lusi thought for a moment, picked up the book and wrote "chocolate" on it.

Delicious candy becomes a deadly poison, and everything starts and ends here.

Lu Siyu raised his head and looked at Song Wen: "I have a bold idea. If my reasoning is correct, I think there may be evidence to prove it is her." Then he paused and said, "but song team, I hope you can promise me one thing first."

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