Criminal Investigation Notes

Lu Siyu and Song Wen came out of a small restaurant and still went back the same way. The tickets they bought were at 1:30 p.m., and it would be a while before they could get to the city. The time was very tight. If they didn't want to break into the station again, they would leave about 10 minutes.

Song Wen went downstairs to see if the old lady was still there. It was lunch break time. The residential area became more and more quiet. The two still climbed up the fourth floor and knocked on the door of Lin wanwan's house. After several minutes, the sound came from inside. Then the door was opened. Wang Wenyan looked up at them through an iron door and was surprised: "you, how did you come back?"

Song Wen said: "Auntie, we still have a few questions that we forgot to ask just now. I want to ask you."

Wang Wenyan looked at him, not as indifferent as when they came for the first time, "I have told you everything I can tell you." She spoke with no intention of opening the door.

Lu Si language frowned slightly after listening to it. This can't be thought about carefully. What's the meaning of being able to tell? What can't be told?

Song Wen took the time to say the subject: "we want to ask about the gas poisoning three years ago."

Wang Wenyan's eyes moved, as if he had been hit by someone suddenly, and his voice trembled a little: "where did you hear that? That matter has nothing to do with what's going on in the dormitory now. Besides, it's been a long time ago, and nobody's been in trouble. "

"Auntie, do you want us to discuss this matter in the corridor?" Lu Si said in a low voice

At this time, they are separated by a burglar proof iron door, Song Wen and Lu Si Yu are standing in the corridor, and Wang Wenyan is standing in the door. Such a station can be seen as long as someone goes upstairs, and some neighbors may also hear it.

Wang Wenyan hesitated for a moment. She didn't want to let them in again, but she didn't want to let others know that it was not a glorious thing for the police to come to the door. In particular, the matter now also concerns her daughter, Lin wanwan.

Song Wen propped up the iron gate with his hand, looked down at her slightly, and looked down at her. She said, "we only ask a few words, and then we will go."

Wang Wenyan lowered her head and opened the door after a sound of the door lock. This time, her attitude was much colder. On the tea table, there were leftovers of just finished food. One dish was a meal. She was frugal and simple. After Song Wen and Lu Siyu entered, she didn't let them sit, let alone pour water.

Song Wen went straight in: "I want to ask about the gas poisoning incident three years ago. Was wan wan not at home at that time? "

Wang Wenyan arms in both hands, "she has the usual habit of going to the library to study, and she went out at six o'clock in the morning."

"When was your poisoning discovered?"

"More than ten. Our house has a ventilation window leading to the corridor. At that time, the corridor was full of gas smell, so someone called the police The things sealed by the memory were suddenly turned out, and Wang Wenyan answered slowly.

Song Wen asked again, "what time do you usually get up in the morning?"

"Seven thirty to eight." Obviously it was gas poisoning, so they didn't wake up on time.

Lu Siyu raised his head and asked, "when Lin wanwan is on holiday, does he go to the library so early? As far as I know, the library won't open so early. " He has just checked the distance between here and the library. The whole town is not big. It takes 15 minutes by car or 30 minutes by walk. The general library will open at 8:30. Even if you go early, it is enough to leave at 7:00. You can also have a breakfast on the way.

Wang Wenyan was obviously stunned for a moment. She didn't know whether it was really unclear or the problem. She didn't think about it carefully: "I I don't know. Usually she's not at home when I get up

Song Wen continued to ask, "what happened to the water on the gas that day?"

Wang Wenyan's face changed. He lowered his head and whispered, "yes I was confused. When I went to the toilet in the morning, I wanted to drink water. When I found that there was no boiling water at home, I burned the water and forgot to turn it off. " This is what she repeated countless times later. Her head is getting lower and lower. If there is a crack in the ground, she would like to get into it.

Looking down at the woman in front of her, Song Wen can feel the guilt on Wang Wenyan. It seems that she regards herself as a sinner: "really? Why do you boil water in the morning? Have you ever done this before? "

Wang Wenyan pursed his lips and shook his head: "I don't remember." She stood there habitually rubbing her hands, like a student who was suddenly scolded by the teacher and could not hand in his homework. The whole person was a little embarrassed.

"After that, did Lin wanwan and you often mention this matter?" Lu Si put in a question.

"She Yes, I am forgetful. " Wang Wenyan lowered her head and stepped back half a step. The words of remorse seemed to be embedded in every wrinkle on her face.

In general, when such an unfortunate event happened in a family, he would avoid it and would not mention it. However, Lin wanwan took it as a handle to coerce his mother and repeatedly mentioned it. She was not afraid of the matter and the result. I don't mind mentioning it will further stimulate my mother.

Lu Si Yu and Song Wen looked at each other, and it was not easy.Song Wen thought about it for a moment and asked, "what I got here was not what you said when someone came to ask questions. You said you didn't light the water. " The old lady was vague. He can only guess and cheat.

Lu Si Yu thought for a while and saw Wang Wenyan's hesitation. "It has been three years since this incident happened. No one will be punished for it, but we want to know the situation." His voice was calm, but his words were like a needle into Wang Wenyan's heart. "If you didn't do this, do you really want to carry on with the accusation that you almost killed your family? If you don't say it now, maybe everyone won't know the truth. "

Wang Wenyan's eyes shook for a moment, as if moved by the words of Lu Si language. In the past three years, she has been suspected and criticized by her family members, and also criticized by outsiders. Everyone looked at her with fear and suspicion, as if she were an attempted killer. But she was stunned for two seconds, and still insisted on the saying: "I don't know I don't know why the fire is burning. I have no impression

How many steps did she take? Was the fire lit before she got up or after she got up. Where was Lin Wan informed? What did she say after you were rescued? "

Lu Si Yu's questions were asked quickly, which brought a sense of oppression to Wang Wenyan. When asked, she could hardly think about it. She shook her head and denied: "no It's not wanwan. It can't be her. My daughter, I know very well Wan Wan said that she was... " At this point, she suddenly stopped, her eyes trembled and her lips closed.

"I didn't say she did it, I just asked when the fire was lit," he said

The woman realized that she had said something wrong, swallowed a mouthful, looked at them helplessly, remained silent for a few seconds, and whispered, "wanwan said She didn't notice if there was a fire on the stove... "

Song Wen's eyes narrowed slightly, cooperating to put pressure on the woman in front of him: "your reaction now seems to be saying that in those years, you also doubted your daughter."

At that moment, Wang Wenyan seemed to have returned to her home three years ago. In the ordinary morning, she heard the sound of Wenwan go out and close the door. Later, she lay on the bed. She had already woken up and wanted to open her eyes, but her body could not move. It seemed that she had been pressed by a ghost. What she smelled in her nose was a strange smell, and she could distinguish the pungent smell at first And then that feeling didn't even exist. She seemed to have been walking along the same road, vaguely feeling that she should not be here, but she could not remember anything.

If you go further, you'll be at the door of death.

After that, for a long time, she was in insomnia. As soon as she closed her eyes, there was a burning flame, gurgling open water. In her sleep, someone pointed to her nose and said that she was a murderer.

Who lit the fire on the stove? Is it herself? Or Or

She couldn't imagine that possibility. She thought of countless reasons for her. Wanwan has a good memory, which she can't forget. Wanwan is her own daughter. She can't light the fire But who else besides her Did she really doubt her daughter?

No!

Wang Wenyan opened her eyes and denied the idea in her mind. It was her own daughter, who was the closest person in the world. When she was young, she once put her arms around her shoulder and said, "Mom, dad doesn't want you. It doesn't matter. I will always accompany you." It was the angel of her life, the hope that she would survive. Even if she is wrong, she can't be wrong.

So it must be that she forgot. Only when she forgot, Wan Wan would blame her with a smile, "Mom, how did you forget it again?"

It must be that she forgets that this home will exist.

Wang Wenyan touched her cheek. She raised her head, waved her hands, and forced her spirit: "no, I didn't It's all I forget. It's my bad memory. I have a bad memory. I always make mistakes. I can't find any good things. I forget to lock the door when I go out. All this has nothing to do with the contract or the cases you investigated. Please don't ask me again. Don't force me any more. " Her eyes were full of prayer and her voice was crying.

Lu Si Yu did not continue to ask, the woman's response has given him the answer, he bit a pen to continue to ask: "do you think, this dormitory thing, is it possible that Wan Wan did it?"

Wang Wenyan continued to deny: "and It has nothing to do with wanwan... " Her eyes are more and more uneasy, but her mouth still insists, as long as she denies it, she can be let go, her daughter will be OK, and this family will be OK. All this is like that thing at that time. It's like a dream. When you wake up, everything will be OK. Everyone in this family is in peace. Those innocent girls, wanwan's classmates, the truth of the matter, she has no control.

"Don't you tell me about your daughter's case?" Song Wen chased her and said, "did you know the police would come before the phone call last night?"

"No No.... " Wang Wenyan was about to cry.Wan Wan called. At that time, she was still in the hospital. It was said that she borrowed the nurse's mobile phone. She said, "Mom, some of my classmates in my bedroom ate the wrong food and went to the hospital. I'm fine here. You don't have to come here. Maybe the police will come to ask about the situation. If they ask you, don't be nervous. Just tell me what you know."

Wang Wenyan was frightened when she just received a call from the school. Later, she received a phone call from Lin wanwan. Her daughter's calm seemed to be her heart set. However, the more she understood the situation, the more frightened she became. She could hardly sleep at night these days. She always felt that someone was standing at the head of the bed when she opened her eyes.

When did it start? Originally should be and her most intimate daughter, suddenly grew up one night, and cold like a piece of ice, less phone calls, less greetings, sometimes she looked at her strange face, even some fear, that is her daughter? Wang Wenyan suddenly felt that something had been put into her chest, which made her have some difficulty breathing.

She felt that she was cowardly, isolated, and dependent on men. She had never lived the life she wanted. She had ardent hope for her daughter. She often said, "your mother is too stupid. You must not follow your mother's path like your mother. You should be selfish, don't learn from your mother, and always live for others. So her daughter was smart, strong and independent. Everyone said she was gentle and likable. She finally became what she wanted to look like. She was hundreds of times stronger than herself. But she knew what was wrong with her daughter.

It seems that after junior high school, Lin wanwan has been very interested in biology. She once saw a dead bird in her room. The bird's claws were tightly curled up, her eyes were open, and her body was completely stiff

"Her classmate was poisoned. The medicine was in chocolate." Lu Si language said the truth, staring at Wang Wenyan, in front of the woman's calm already no longer exist.

Wang Wenyan instantly thought of the box in her daughter's room stacked with chocolate candy paper and wanwan's favorite chocolate. It's no wonder that the two policemen looked at it so strangely before. She still remembers that Wan Wan once said with a smile, "Mom, if I die one day, I will make chocolate my last supper, because there is nothing better than it in this world." At that time, she said in a hurry, "Pooh, what do you say when you are young."

"Stop it! Don't say any more! " Wang Wenyan, like a wounded deer, was driven to a desperate situation by the hunter. He was injured, and his blood flowed all over the ground and gave out a cry of despair.

For a moment, it was as if someone had struck a match, and the orange red flame shot up and was thrown into the room full of gas. With a loud bang, Wang Wenyan seemed to feel that something had been blown up in her mind. The fire was burning her flesh and blood. Everything was burnt out in the sky. All the things were gone and could never come back again.

Wang Wenyan's hands were shaking like a sieve, and her eyes finally shed tears. She kept repeating, "it's all my fault..." It seems that no matter who is right and who is wrong, as long as you repeat this sentence, as long as you hold on to yourself, you can solve it.

In the face of the collapse of Wang Wenyan, Song Wen did not continue to ask, put out a professional smile: "Auntie, thank you for your cooperation in our work, we will not be able to catch the train again." After saying this, he winked at Lu Si Yu and came out of the door, leaving Wang Wenyan crying bitterly.

They went downstairs, took a taxi with the taxi software, got on the car and sat in the back seat. Song Wen whispered, "what Wang Wenyan said is true. She knows her daughter very well. Perhaps Lin wanwan had already called and told them not to talk to the police. She might have thought about the possibility that her daughter was the killer. The first time we went, she was ready, tight and careful. When we went back the second time, she didn't expect us to come back again. She was very flustered and missed her feet

Lu Si Yu looks at Song Wen: "have you heard of the gas lamp effect?"

Song Wen shook his head.

"It's a psychological term, a method of emotional violence and manipulation," Lusi explained. It originated from a movie named HT. The husband in the film keeps telling his wife that you are mentally ill and your memory is not good. He deliberately steals the things his wife has left, and then accuses her of remembering the wrong place. Step by step, the wife is tortured to madness by her husband's lies and manipulation. This kind of control is not achieved overnight, but gradually formed in daily life. The operator will constantly deny and distort the facts, indoctrinate the wrong information to the other party and mentally torture the other party. "

Song Wen asked, "is this a kind of spiritual manipulation?"

"It's a chronic mental devastation, and many people don't know it." Looking at Song Wen, "I think Wang Wenyan's state is a bit similar."

Song Wen frowned: "are you inferring from Li Zichen's accusation and Wang Wenyan's performance?" He has taken some courses in criminal psychology, and he knows that psychological manipulation sounds abstruse, but it can be manipulated.

Lu Siyu nodded, forgetful and useless, so her sister didn't go home. Naturally, Li Zichen was born with these attitudes. If these childish words are linked together, we can see Lin wanwan's consistent attitude towards his mother. And Wang Wenyan's confused and fragile state, some abnormal state.Lin wanwan has no feelings for the mother and the family. Wang Wenyan is forgetful and cowardly. She puts herself in a low position. She owes her daughter. If her personality and psychology are controlled, she will be a puppet who does not know how to resist. Maybe she did have some forgetfulness at the beginning, but she was constantly criticized and bullied by her family members, and the facts in her eyes and hearts were constantly distorted, which undoubtedly aggravated these.

In her life, it was like someone had lit a gas lamp, which was on and off.

Did Wang Wenyan really light the gas that morning?

I'm afraid it's all vague in her own memory. Maybe she did. Maybe she didn't. Maybe at that time Lin wanwan saw the burning water. Maybe the pot of water was Lin wanwan who put it on the stove. Or maybe she's really innocent, completely unaware. It happened three years ago, and no one died. The truth of the matter is completely out of the question.

In this family, it is impossible for Wang Wenyan to be manipulated by her husband who is not at home all the year round, not her minor son, but her daughter who lived at home before. Lu Siyu confirms more and more that Lin wanwan is a controlling personality, but this kind of manipulation has weakened with the residence of the girl.

The sun shone on Lu Siyu's snow-white face, his black eyes moved slightly, and he said, "I think every criminal, the reason and process of his crime, are inseparable from his growth experience. Most killers have some symptoms and behavior escalation, such as killing animals and injuring others. If it is not her mother who forgot to turn off the gas that day, it may be an attempt

In that morning, the girl, probably standing not far from downstairs, was staring at the window, waiting for the gas to devour the lives of her relatives. She wiped off her fingerprints and thought out a good excuse. Unfortunately, her family was saved. For such a long time, she never showed any regret and fear for this matter.

What Lusi is saying now is only speculation, but it is bolder than before.

Then, Lin Wan Wan Wan's suspicion, again a point. Just, why did she kill those classmates who were sleeping with her?
