Criminal Investigation Files

Lu Siyu and Song Wen came out of the small restaurant and returned the same way. The tickets they bought were at 01:30 in the afternoon. It would take a while to get to the city. The time was very tight. Leave on for 10 minutes or so.

Song Wen went downstairs and checked to see if the old lady was still there. It was lunch break and the residential area was getting quieter. The two climbed up to the fourth floor and knocked on the door of Lin Wanwan's house. It took a few minutes before there was a sound from inside, and then the door was opened. Wang Wenyan looked up at them through an iron door and was a little surprised: "You guys, why are you back again?"

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

Wang Wenyan looked at him, not as indifferently as when they first came, "I've told you all I can tell." She was speaking, not intending to open the door at all.

Lu Siyu frowned slightly when he heard it behind him. He couldn't think about it carefully. What does it mean to be able to tell?What else can you not tell?

Song Wen seized the time and got straight to the point: "We want to ask about the gas poisoning incident three years ago."

Wang Wenyan's eyes moved, as if someone had suddenly tapped her acupoints, her voice trembling: "Where did you hear that? That incident has nothing to do with what is happening in Wanwan's dormitory now. Besides, that incident has long been It’s over, and no one has had an accident.”

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

At this time, they were talking to each other through an anti-theft iron door, Song Wen and Lu Siyu were standing in the corridor, and Wang Wenyan was standing inside the door.Such a position 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 also didn't want others to know that it was disgraceful for the police to come to her door.Especially, this matter is still related to her daughter, Lin Wanwan.

Song Wen supported the iron gate with his hands, slightly lowered his head and looked down at her, as if he would not give up until he entered the door: "We just ask a few words, and we will leave after we finish."

Only then did Wang Wenyan lower her head, and opened the door after a sound of the door lock. This time, her attitude was much colder. There were leftovers on the tea table, one dish and one meal, frugal and simple. After entering with Lu Siyu, she didn't let them sit down, let alone pour water.

Song Wen went straight to the point: "I want to ask about the gas poisoning incident three years ago. Wasn't Wanwan at home at that time?"

Wang Wenyan crossed her arms and hummed, "She has the habit of going to the library to study, and she goes out after six o'clock in the morning."

"When was your poisoning discovered?"

"It's past ten o'clock. Our house has a ventilation window leading to the corridor. At that time, the leak made the corridor full of gas smell, so someone called the police." The matter that was sealed in memory was suddenly revealed, and Wang Wenyan replied Be a little slow.

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

"07:30 to [-] o'clock." Obviously gas poisoning, so they didn't wake up on time.

Lu Siyu raised his head while recording and asked, "Does Lin Wanwan always go to the library so early when she is on vacation? As far as I know, the library won't open so early." He just checked The distance from here to the library is small. It takes 15 minutes by car, or 30 minutes by foot.The general library will not open until 08:30. Even if you go early, it is enough to go out at [-] o'clock, and you can also have breakfast on the way.

Wang Wenyan was obviously stunned for a moment. She didn't know if she really didn't know or she hadn't thought about this question: "I... I don't know. Usually she is not at home when I wake up."

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

Wang Wenyan's expression changed, she lowered her head, and said in a low voice, "Yes... I was confused. I wanted to drink water when I went to the toilet in the morning, but 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 was getting lower and lower, if there was 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 did you boil water in the early morning? You have done this kind of thing before. ?"

Wang Wenyan pursed her lips and shook her head: "I don't remember." She stood there rubbing her hands habitually, like a student who was suddenly scolded by the teacher for failing to hand in her homework, feeling a little embarrassed.

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

"She... mentioned it, blame me for being forgetful." Wang Wenyan lowered her head and took half a step back, the words "blame herself" seemed to be embedded in every wrinkle on her face.

In ordinary families, when such an unfortunate thing happened, they would avoid it and would not bring it up, but Lin Wanwan took it as an excuse to blackmail her mother and repeatedly mentioned it.She is not afraid of this matter and the result at all.I also don't mind mentioning it to further irritate my own mother.

Lu Siyu and Song Wen glanced at each other, it really wasn't easy.

Song Wen thought about it for a while, and then asked: "You didn't say that when someone came to ask about the information I got here at first. You said that you didn't light the water." The old lady said vaguely before.He can only guess and cheat.

Lu Siyu thought about it for a while, and saw Wang Wenyan's hesitation, "Three years have passed since this incident, and no one will be convicted of it, but we want to understand the situation." His voice was calm, and he said His words pierced Wang Wenyan's heart like a needle, "If you didn't do this, do you really want to continue living on the charge of nearly killing your family? If you don't say it now, then Maybe everyone won't know the truth."

Wang Wenyan's eyes twitched, as if she was moved by Lu Siyu's words. In the past three years, she has been suspected and criticized by her family members, and also 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, and still insisted on what she just said: "I don't know... I don't know why the fire is burning, I have no impression."

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

Lu Siyu asked the question very quickly, which brought a sense of oppression to Wang Wenyan. She almost had no time to think about it, and shook her head in denial: "No...it's not Wanwan, it can't be hers, I I know her daughter very well... Wanwan said that day..." At this point, she paused suddenly, her eyes trembled, and her lips were pursed.

Lu Siyu said: "I didn't say 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, "Wanwan said...she didn't pay attention to whether there was fire on the stove..."

Song Wen's eyes narrowed slightly, and he cooperated with the pressure on the woman in front of him: "Your reaction now seems to be saying that you also doubted your own daughter about what happened back then."

Hearing these words, at that moment, Wang Wenyan seemed to have returned to her home three years ago. On that ordinary morning, she heard the sound of Wanwan going out to close the door. Later, she was lying on the bed, obviously awake, and wanted to open the door. Eyes, but the body can’t move at all, as if being pressed by a ghost, what smells in the nose is a strange smell, at first I can still distinguish the pungent smell, and then even that feeling doesn’t exist anymore.She seems to have been walking on the same road, vaguely feeling that she shouldn't be here, but she can't remember anything.

Going any further is the gate of death.

For a long time after that, she suffered from insomnia, as soon as she closed her eyes, there would be a burning flame, gurgling boiling water, and someone pointed to her nose in her sleep, saying that she was a murderer.

Who lit the fire on the stove?Is it herself?still... still...

She didn't dare to imagine that possibility, she thought of countless reasons for herself, Wanwan has a good memory, she can't forget it, Wanwan is her own daughter, she can't light the fire... But, besides her Who... had she really doubted her daughter?

Do not!

Wang Wenyan's eyes widened, and she denied the thought in her mind. That was her own daughter, the closest person she ever had in the world. When she was young, she once put her arms around her shoulders and said, "Mom, it's okay if Dad doesn't want you anymore." , I will always be with you." That was the angel in her life, her hope of surviving.Even if she is wrong, she will not be wrong.

Therefore, it must be that she forgot, and only if she forgot, would Wanwan laugh and accuse her, "Mom, why did you forget again?"

It must also be that she had forgotten that this family would exist.

Wang Wenyan touched her cheek, she raised her head, waved her hands, and tried her best: "No, I didn't... I forgot it all. It's my fault. I have a bad memory. I always go wrong. No, I will forget to lock the door when I go out. None of this has anything to do with Wanwan, and it has nothing to do with the case you are investigating, please stop asking, and stop forcing me." Her eyes were full of pleading, and her voice was full of tears sound.

Lu Siyu didn't continue to ask, the woman's reaction had already given him the answer, he bit his pen and continued to ask: "Do you think it's possible that Wanwan did what happened in the dormitory this time?"

Wang Wenyan continued to deny: "It has nothing to do with... and Wanwan..." Her eyes became more and more uneasy, but her mouth was still persistent, as if as long as she continued to deny, she would be let go and her daughter would be fine. it will be fine.All of this is just like that incident at that time, like a dream, when I wake up from the dream, everything will be fine, everyone in this family is here, and it is safe.Those innocent girls, Wanwan's classmates, the truth of the matter, she can't control these anymore.

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

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

Wanwan called. She was still in the hospital at that time. It is said that she borrowed the nurse's mobile phone. She said, "Mom, a classmate in my dormitory ate something wrong and went to the hospital. I'm fine here. You don't need to come over. Maybe the police will come to ask about the situation, and if they ask you later, don’t be nervous, just say what you know.”

When she first received a call from the school, Wang Wenyan was terrified. Later, when she received a call from Lin Wanwan, her daughter's calmness seemed to be her anchor, but the more she understood the situation, the more terrified she became. She could hardly sleep at night these days. Sleepy, when I open my eyes, I feel someone standing on the head of the bed.

When did it start?The daughter who was supposed to be the closest to her suddenly grew up overnight, and it was as cold as a piece of ice. There were fewer calls and fewer greetings. Sometimes when she looked at her strange face, she would feel a little nervous Scared, is that still her daughter?Wang Wenyan suddenly felt as if something was stuffed into her chest, which made her a little short of breath.

She feels cowardly, withdrawn, very dependent on men, and has not lived the life she wanted. She has ardent hopes for her daughter, and often says, your mother is too stupid, you must not be like your mother, leave you Mother's way, you have to be selfish, don't be like your mother, always live for others.So the daughter is smart, strong, independent, and everyone says she is gentle and lovable, and she finally becomes what she wants, hundreds of times and a thousand times stronger than herself.But she knew that something was wrong with her daughter.

It seems that since junior high school, Lin Wanwan has been very interested in creatures. She once saw a dead bird in her house. The bird's claws were tightly curled up, its eyes were open, and its body was black 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 had long since disappeared.

Wang Wenyan instantly thought of the box of chocolate wrappers in her daughter's room, Wanwan's favorite chocolate.The rewards she received every time she got good grades, no wonder the two policemen looked at that thing so strangely.She still remembered that Wanwan once said with a smile: "Mom, if one day I die, I must have chocolate as my last supper, because there is nothing more delicious than it in this world." At that time, she Hastily said: "Hurry up, what did you say at a young age?"

"Don't say it! Don't say it anymore!" Wang Wenyan was like a wounded deer who was cornered by a hunter. He was injured and blood flowed all over the ground, sobbing in despair.

For a moment, it was as if someone struck a match, and the orange-red flame jumped up and was thrown into the room full of gas.There was a loud bang, and Wang Wenyan felt as if something had been blown up in her mind, and the flames were burning her flesh and blood. In the flames, everything was burnt out, everything disappeared, and there was no way to start over again. .

Wang Wenyan's hands were shaking like sieves, and tears finally slipped from the corners of her eyes. She kept repeating, "It's all my fault..." It seems that no matter who is right or wrong, right or wrong, as long as she repeats this sentence, As long as you hold it on your own body, it can be solved.

Facing the collapsed Wang Wenyan, Song Wen did not continue to ask, but put on a professional smile: "Auntie, thank you for cooperating with our work, we will miss the train if we don't go back." After saying this, he said to Lu Si Yu winked and walked out the door, leaving Wang Wenyan crying bitterly.

The two went downstairs, used the taxi app to hail a taxi, got into the car and sat in the back seat, Song Wen whispered: "What Wang Wenyan said is correct, she knows her daughter very well. Maybe Lin Wanwan has already Called and told them not to say anything to the police. She may have also considered the possibility that her daughter was the murderer. The first time we went, she was prepared, tense and careful, and our second When she went back for the first time, she didn't expect us to come again, she was very flustered and missed her feet."

Lu Siyu looked at Song Wen: "Have you heard of the gaslight 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". In the movie, the husband kept talking to his wife. Instill the information that you are mentally ill and your memory is bad. He deliberately stole the things his wife put away, and then accused her of misremembering the location. The wife was tortured to the point of insanity by her husband’s lies and manipulation step by step. This kind of Control is not achieved overnight, but is gradually formed in daily life, and the manipulator will constantly deny and distort the facts, instill false information into the other party, and mentally torture the other party."

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

"It's a kind of 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: "You inferred from Li Zichen's accusation and Wang Wenyan's performance?" He had studied some criminal psychology courses, and he knew that psychological manipulation sounds mysterious, but it is actually manipulable.

Lu Siyu nodded, forgetful, it's useless, her sister didn't go home because of this, these attitudes naturally couldn't be born with Li Zichen, these children's words are linked together, it can be seen that Lin Wanwan has always treated her mother Attitude.And Wang Wenyan's confused and fragile state is a bit abnormal.

Lin Wanwan has no feelings for this mother or this family. Wang Wenyan is forgetful, cowardly, and puts herself in a very low position. She owes her daughter something. If this character and psychology are manipulated, she will become a A puppet who knows no resistance.Maybe she did have some forgetfulness at the beginning, but she was constantly accused and bullied by her family, and the facts in her eyes and heart were constantly distorted, which undoubtedly aggravated these things.

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

Did Wang Wenyan really go to light the gas that morning?

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

In this family, the one who manipulated Wang Wenyan before could not be her husband who was away all year round, not her underage son, but her daughter who lived at home before. Lu Siyu became more and more sure that Lin Wanwan was a controlling type. Personality, just this kind of manipulation, has weakened with the daughter's boarding school.

The sun shone on Lu Siyu's snow-white face, his black eyes moved slightly, and he said again: "I think that every criminal, the reason and process of committing a crime are inseparable from his growth experience. Most Killers have some signs and escalated behaviors, such as 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."

On that morning, that girl may have been 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 of an excuse, but unfortunately her family was rescued. up.For so long, she never showed any regrets or fears about this matter.

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

Then, Lin Wanwan's suspicion has increased again.But, why did she kill those classmates who slept with her?
