Criminal Investigation Notes

Lu Siyu and Song Wen came out of the small restaurant and returned the same way. They bought the ticket at 1:30 in the afternoon. It will take a while to get to the city. Time is very tight. If you don’t want to go to the station, they will stay. The next ten minutes or so.

Song Wen arrived downstairs, and specifically checked whether the old lady was still there. This was the lunch break. The residential area became quieter and quieter. The two of them climbed up to the fourth floor and knocked on the door of Lin Wanwan's house. For several minutes, a sound came from inside, and then the door was opened. Wang Wenyan looked up at them with an iron door in surprise: "You guys, why are you back again?"

Song Wendao: "Auntie, we have a few more questions that we forgot to ask just now, we want to ask you."

Wang Wenyan looked at him, not as indifferently as when they came the first time, "I will tell you what I can tell you." She said, without opening the door at all.

After listening to Lu Siyu, he frowned slightly. I can't think about these words carefully. What does it mean to tell?What else can't be told?

Song Wen hurriedly said the subject: "We want to ask about gas poisoning three years ago."

Wang Wenyan's eyes moved, as if he was suddenly tapped on the acupoint, and her voice was a little trembling: "Where did you hear about it? That matter has nothing to do with the things in Wanwan's bedroom now. Moreover, it was early. It passed, no one had an accident."

Lu Siyu reminded in a low voice: "Auntie, do you want us to discuss this in the corridor?"

At this moment, they were speaking across an anti-theft iron gate. Song Wen and Lu Siyu were standing in the corridor, and Wang Wenyan was standing inside the gate.Such a station can be seen as long as someone goes upstairs, and some neighbors may also hear it.

Wang Wenyan hesitated, she didn't want to let them in again, but she didn't want to let others know, after all, it is not a glorious thing for the police to come to the door.Especially, this matter now concerns her daughter, Lin Wanwan.

Song Wen put his hand on the iron gate, lowered his head slightly and looked down at her, swearing that he would never give up if he didn't enter the door: "We only ask a few words, and we will leave after we ask."

Wang Wenyan lowered her head, and opened the door after the lock rang. This time, her attitude became much colder. There were leftovers leftovers from the meal just finished on the coffee table, one dish and one meal, frugal and simple, waiting for Song Wen She didn't let them sit after entering with Lu Siyu, let alone pouring 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 hugged her arms and said, "She has the habit of going to the library to study, and she left after six in the morning."

"When was your poisoning situation discovered?"

"It's over ten o'clock. There is a ventilation window leading to the corridor in our house. At that time, there was a gas leak in the corridor. Someone called the police." The memory sealed up was suddenly turned over, Wang Wenyan replied It's a bit slow.

Song Wen asked again: "What time do you usually get up in the morning?"

"7:30 to 8:00." It was obviously because of gas poisoning, so they didn't wake up on time.

Lu Siyu looked up and asked, "Did Lin Wanwan go to the library so early during holidays? As far as I know, the library will not open so early." He just checked. After the distance from here to the library, the whole town is not big. It takes 15 minutes by car, even if it is a walk, it can be more than 30 minutes.Normal libraries won’t open until half past eight. Even if you go early, it’s enough to leave at seven.

Wang Wenyan was stunned for a moment. I don't know if it's really unclear or she hasn't thought about this question carefully: "I...I don't know. Generally, she is not at home when I wake up."

Song Wen continued to ask: "What happened to the water on the gas that day?"

Wang Wenyan's face changed, she lowered her head, and whispered: "Yes...I am confused. When I went to the toilet in the morning, I wanted to drink water. I found that there was no boiling water at home, so I boiled the water and forgot to turn it off." It was the rhetoric she repeated countless times later. Her head lowered and lowered. If there is a crack in the ground, she would like to get in.

Song Wen looked down at the woman in front of him, and could feel Wang Wenyan's guilt. It seemed that she regarded herself as a sinner: "Really? Why do you boil water in the morning? You have done this before. ?"

Wang Wenyan pursed her lips and shook her head: "I don't remember." She stood there habitually rubbing her hands, as if suddenly being questioned by the teacher, the students who couldn't hand in their homework were a little embarrassed.

"After that, did Lin Wanwan and you often bring up this matter?" Lu Siyu intervened and asked.

"She... mentioned it and blamed me for forgetfulness." Wang Wenyan lowered her head and took a half step back. The word self-blame seemed to be embedded in every wrinkle on her face.

Ordinary families would avoid such unfortunate incidents and would not mention them, but Lin Wanwan used it as a handle to threaten her mother and repeatedly mentioned it.She is not at all afraid of this matter and the result.Don't mind that mentioning it will further stimulate your mother.

Lu Siyu and Song Wen looked at each other, and it was not easy.

Song Wen thought about it and asked, "The information I got here, when someone came to ask questions, you didn't say that. You said that the water was not ignited by you." The old lady said vaguely.He can only guess and deceive.

Lu Siyu thought about it and saw Wang Wenyan's hesitation, "It has been three years since this incident. No one will be guilty of it, but we want to understand the situation." His voice was calm and he spoke out. But it seemed like a needle pierced Wang Wenyan’s heart, "If you didn’t do this, do you really want to carry on with the charge of almost killing your own family? If you don’t say it now, then Maybe no one will know the truth."

Wang Wenyan's eyes shook, as if she was moved by Lu Siyu's words. In the past three years, she has been suspected and accused by her family, and she has also been pointed out by outsiders.Everyone looked at her with fear and suspicion, as if she was an attempted murderer.But she was stunned for two seconds, still insisting on what she said earlier: "I don't know... I don't know why the fire was burning, I have no impression."

Lu Siyu continued, and he took a step forward, "Then what about your daughter Lin Wanwan, when did she leave? Was the fire lit before she got up or after she got up. Who was Lin Wanwan by? Informed, where was she at that time? How did she explain it after you were rescued?"

Lu Siyu's question was asked very quickly, which brought Wang Wenyan a sense of oppression. When being asked so much, she hardly had time to think, and shook her head to deny: "No... it's not Wanwan, it can't be hers, I I know her daughter very well... Wan Wan said that she said that that day..." At this point, she suddenly paused, her eyes trembled and her lips pressed.

Lu Siyu said: "I didn't say that she did it. I just asked when the fire was lit."

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

Song Wen's eyes narrowed slightly, and he cooperated to put pressure on the woman in front of him: "Your current reaction seems to be saying that you had doubts about your daughter in the past."

Hearing these words, at that moment, Wang Wenyan seemed to have returned to her home three years ago. In that ordinary morning, she heard the sound of Wan Wan going out and closing the door. Later, she was lying on the bed, clearly awake and wanted to open it. My eyes, but my body couldn't move, as if I had been pressed by a ghost. I smelled a strange smell in my nose. At first I could distinguish the pungent nose, but later it didn't even exist.She seemed to have been walking on a road, vaguely feeling that she shouldn't be here, but she couldn't remember anything.

Going further forward is the ghost gate of life and death.

For a long time after that, she was suffering from insomnia. As soon as she closed her eyes, there was the burning flame and the gurgling open water. In her sleep, someone pointed to her nose and said she was a murderer.

Who lit the fire on the stove?Is it herself?Still...or...

She didn't dare to imagine that possibility. She thought of countless reasons for herself. Wan Wan has a good memory, which she can't forget. Wan Wan is her biological daughter. She can't set the fire on... But besides her Who else... Did she really doubt her daughter?

Do not!

Wang Wenyan opened her eyes wide and denied the idea in her mind. It was her own daughter, who was the closest person to her in the world. As a child, she once put her arms around her shoulders and said: "Mom, it doesn't matter if I don't want you. , I will always be with you." That is the angel in her life, the hope for her to survive.Even if she was wrong, she wouldn't be wrong.

So, she must have forgotten it herself. Only if she forgot, Wan Wan would smile and accuse her, "Mom, why did you forget it again?"

She must have forgotten for this home to exist.

Wang Wenyan touched her cheek, she raised her head, waved her hand, and beat her spirit: "No, I didn't...I forgot it. It's me. I have a bad memory. I always go wrong. I look for good things. If you don’t go out, you’ll forget to lock the door. All of this has nothing to do with Wanwan, and it has nothing to do with the case you are investigating. Please stop asking and don’t force me." Her eyes were full of pleading, and her voice was crying. sound.

Lu Siyu did not continue to ask. The woman's response had already given him an answer. He bit the pen and continued to ask: "Do you think Wanwan did the things in the dormitory this time?"

Wang Wenyan continued to deny: "It has nothing to do with...and Wanwan..." Her eyes became more and more disturbed, but she persisted. As long as she denies it, she can be let go and her daughter will be fine. It will be fine.All this is just like the incident at the time, like a dream. When the dream wakes up, everything is fine. Everyone in this family is there, peaceful.Those innocent girls, Wan Wan's classmates, the truth of the matter, she can no longer control them.

"You don't know the specifics of their dormitory case. Did your daughter tell you to say that?" Song Wen followed her closely. "Did you know that the police would come before the call last night?"

"No...no..." Wang Wenyan was about to cry.

Wan Wan had called. At that time she was still in the hospital. It is said that she borrowed the nurse’s cell phone. She said, “Mom, a classmate in my dormitory ate the wrong food and entered the hospital. I’m fine here. The police may come to ask about the situation. If they ask you later, don’t be nervous, just know what to say."

When she first received a call from school, Wang Wenyan was panicked. Later, she received a call from Lin Wanwan. Her daughter's calmness seemed to be her reassurance, but the more she understood the situation, the more panicked she became. In the past few days, she could hardly Mei, always when I open my eyes, I feel that someone is standing by the bed.

When did it start?She should have been the daughter who was the closest to her. Suddenly she grew up overnight, and she was as cold as a piece of ice. There were fewer phone calls and fewer greetings. Sometimes when she looked at her strange face, there was something unexpected. Afraid, is that still her daughter?Suddenly, Wang Wenyan felt that something was stuffed in her chest, which made her breathless.

She feels that she is cowardly, withdrawn, and very dependent on men. She has been living a life that is not what she wants. She has ardent hopes for her daughter. She often says that your mother is too stupid. You must not leave you like your mother. Mother's way, you have to be selfish, don't learn from mother, always live for others.So my daughter was smart, strong, and independent. Everyone said she was gentle and likable. She finally became what she wanted, a hundred 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 house. The bird’s paws are tightly curled up, her eyes are open, her body is black and black. Has been completely stiff...

"Her classmate was poisoned, and the medicine was put in the chocolate." Lu Siyu told the truth, staring at Wang Wenyan, the calmness of the woman in front of him no longer existed.

Wang Wenyan instantly thought of Wan Wan's favorite chocolate in the box stacked with chocolate candies in her daughter's room.She can receive the awards she can receive every time she gets good grades, no wonder the two policemen looked so strange when they looked at the thing.She still remembers that Wan Wan once said with a smile: "Mom, if one day I die, I will definitely treat chocolate as the last supper, because there is no better food in this world." She was at that time. He hurriedly said: "Quickly drank, what did you say at a young age."

"Stop talking! Stop talking!" Wang Wenyan was like a wounded deer, driven to desperation by the hunter, injured, blood shed all over the place, and let out a desperate sob.

For an instant, as if someone had struck a match, the orange-red flame jumped and was thrown into the room full of gas.With a loud bang, Wang Wenyan seemed to think that something had been blown off in her mind. The flames burned her flesh and blood, and the flames blazed into the sky. Everything was burned out, and everything was gone, and could never be repeated. .

Wang Wenyan's hands shook like a sieve, tears slid from the corner of her eyes, she kept repeating, "It's all my fault..." It seems that no matter who is right or wrong, right or wrong, just repeat this sentence. As long as it is on one's body, it can be solved.

Facing the collapsed Wang Wenyan, Song Wen did not continue to ask, and put on a professional smile: "Auntie, thank you for cooperating with our work. We won't be able to catch the train if we don't go back." He said to Lu. Si Yu winked and walked out of the door, leaving Wang Wenyan crying bitterly.

The two went downstairs, used a taxi app to rent a taxi, got in the taxi and sat in the back seat, Song Wen whispered: "Wang Wenyan is right, she knows her daughter well. Maybe Lin Wanwan has long been I called and told them not to tell the police anything. She might have considered the possibility that her daughter was a murderer. When we went for the first time, she was prepared, tight and cautious, and we were second When we went back the next time, she didn't expect us to come again. She was very panic and missed her feet.

Lu Siyu looked at Song Wen: "Have you heard of the gas lamp effect?"

Song Wen shook his head.

Lu Siyu explained: "This word is a psychological term, a method of emotional violence and manipulation. It originated from a movie named "gaslight". The husband in the movie constantly treats his wife Instill the message that you are mentally ill and your memory is not good. He deliberately stole the things that his wife had left, and then accused his wife of misrepresenting the position. Then the wife was tortured step by step by his husband’s lies and manipulations. Control is not achieved overnight, but slowly formed in daily life. The manipulator will constantly deny and distort facts, instill wrong information into the other party, and mentally torture the other party."

Song Wen asked: "Is this a kind of spiritual manipulation?"

"It's a chronic mental torture. Many people are in it but don't know it." Lu Siyu looked at Song Wen, "I think Wang Wenyan's state is a bit similar."

Song Wen frowned: "Did you infer from Li Zichen's accusation and Wang Wenyan's performance?" He had learned some criminal psychology courses, and knew that psychological manipulation sounds mysterious, but it is actually manipulable.

Lu Siyu nodded, forgetful and useless, so my sister did not go home. Naturally, these attitudes could not have been born with Li Zichen. These childish words linked together, we can see that Lin Wanwan always treated her mother. Attitude.But Wang Wenyan's confused and fragile state is somewhat abnormal.

Lin Wanwan has no feelings for this mother and for the family. Wang Wenyan is forgetful and cowardly, and puts her posture very low. She owes her daughter something. If this kind of character and psychology is manipulated, she will be a A puppet who doesn't know how to resist.Maybe she did have some forgetfulness at first, but she was constantly accused and oppressed by her family, and the facts in her eyes and hearts were constantly distorted, which undoubtedly aggravated these.

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

Did Wang Wenyan really lit the gas that morning?

I'm afraid this is all vague in her own memory.Maybe she ordered, maybe she didn't order.Maybe Lin Wanwan saw the burning water at that time, maybe the pot of water was simply Lin Wanwan put on the stove.Or maybe she is really innocent and completely unaware.It happened three years ago, no one died because of it, and the truth of this incident is completely unsearchable.

In this family, Wang Wenyan was previously manipulated. Naturally, it could not be her husband who was absent from home all the time, not her underage son, but her daughter who lived at home before. Lu Siyu increasingly confirmed that Lin Wanwan was a controlling type. Personality, just this kind of manipulation, has weakened as the daughter lives in school.

The sun shone on Lu Siyu's snow-white face, his black eyes moved lightly, and he said, "I think that every criminal, the cause and process of the crime are inseparable from his growth experience. Most of them. The murderers have some signs and behavior escalations, such as torturing and killing animals and hurting others. If it is indeed not her mother who forgot to turn off the gas that day, then this may be an attempt."

In that morning, the girl might be standing not far downstairs, staring at the window, waiting for the gas to devour the lives of her relatives. She wiped off her fingerprints and thought about excuses. Unfortunately, her family was saved. Up.For so long, she has never expressed any regret or fear about this incident.

What Lu Siyu said now is only speculation, but it is bolder than before.

Then, Lin Wanwan's suspicion was another point.But why did she kill those classmates who were sleeping together?
