Criminal Investigation Notes

Qincheng is located in the north of Nancheng. The temperature is three or four degrees lower than that of Nancheng. After getting off the train, Lu Si Yu took a deep breath of fresh air, and then coughed by the cold and sandy wind. Compared with the southern spring, green trees, here is still a wilderness, the sky, the earth, people, eyes are all gray soil, even the people's accent is full of dry, that kind of stem also implies a kind of liquor spicy.

Song Wen came to Qincheng for the first time. He didn't feel used to it. The average height of the people here seems to be higher than that of Nancheng. Fortunately, they are tall, so they don't stand out in the crowd.

You can't pay attention to business trip any more. Two people have breakfast at the breakfast stall outside the railway station. Song Wen eats soybean milk fried dough sticks. Lu Siyu asks for a piece of porridge and a piece of tofu milk.

After dinner and on the road, Lin wanwan's home is not in the city, but in the nearby town. Under the insistence of Lushi language, they did not take the intercity bus any more, but took a taxi. They struggled all the way to find the past according to the address, and finally came to Lin wanwan's home.

It's a community with eight floors and no elevators. All the people's windows are equipped with anti-theft iron bars of different specifications. It looks a bit messy. Clothes and quilts of various colors are hung outside the balcony. The corridor is narrow and dark, and the doors are piled with sundries. This style is rare in the south. Fortunately, it is close to the north Even if the corridor is dark, it is not moldy.

Song Wen walks to the door of 403 and knocks. Yesterday, he has asked Zhu Xiao to contact Lin wanwan's family. Lin wanwan's stepfather is a long-distance driver. He is not at home all the year round. The destination of this trip is very far, so they have to wait four or five days to go home. So they have to make an appointment with Lin wanwan's mother and ask her not to go out today.

When the door opened, someone first looked through the iron door, then the inner layer opened and poked out a woman's head. This is a woman in her forties with a horsetail, but her hair is yellow and sparse. It seems that her sleep is not good. Her eye socket is very deep, the dark circles are serious, and the eight character pattern is a little deep. Her clothes are simple and clean. In her body, Song Wen sees the softness of Lin wanwan.

Song Wen showed his police card and explained his intention. The woman introduced them to the door. The room was not big, but the floor was not low. This room was not the same as the popular pattern in the south. There was almost no dining room. The living room was a place for eating and watching TV. Then there were two rooms, one for adults and one for children.

As Lin wanwan's mother looked for a cup to pour water for them, she said, "after that, I'm worried. My son is still studying, and his father is not here. The school teacher said that she has nothing to do, so I didn't rush to go there, but I remember that I couldn't sleep well." She opened the cupboard and said, "Oh, my memory, where is the tea?"

After hearing this, Song Wen slightly pursed his lips and exchanged eyes with Lu Siyu. He thought that Lin wanwan's parents didn't come because of the bad family relationship. However, listening to the woman's concern, it didn't seem to be a fraud. Song Wen saw that woman was still squatting in the kitchen looking for tea and said, "Auntie, don't be so polite. Let's sit for a while and then go. That's to understand the family situation of xiawanwan."

Lu Si read about this woman before she came here. Her surname is Wang, and her name is Wang Wenyan. She worked in a clothing factory in the south of China in the early years. Later, she worked in a supermarket here and stayed at home for the last two years.

After listening to Song Wen's words, Wang Wenyan didn't get tangled. He gave Song Wen and Lu Si yuduan two cups of water. He also poured himself a cup and sat on the stool opposite the sofa.

As usual, Song Wen asked questions, and Lu Siyu opened the book. Song Wen went through a process and asked about some basic information, the age and work of family members, and then cut into the main topic: "Auntie, can you tell me something about your daughter?"

Wang Wenyan said: "my family wanwan is a good child. From childhood to adulthood, he has never let the adults worry about him. When he goes to school, he studies well and is clever and sensible. I'm not good... "

Speaking of this, she sighed, as if recalling her unfortunate marriage: "my ex husband's family is more traditional, a little more male than female. After I married in the past, women can't go to the table. When Wan Wan was born, my mother-in-law was not willing to say that I was a money losing commodity. His son was passed on by three generations, and he was going to be broken when he came to me I had porridge for a month. At that time, I was so thin that I was almost depressed. Later, they wanted to force me to divorce my ex husband and let him marry another woman and give them a son. At that time, I didn't want to get divorced, so I put my daughter there and hid myself to work. "

When Wang Wenyan mentioned Lin wanwan, there was a kind of pride that was hard to hide, but there was also a trace of debt at the same time.

"Who took care of Lin wanwan when she was at your ex husband's house?"

"It's mainly my mother-in-law. She is a woman with a knife and a heart full of bean curd. Although she refuses to give up on her mouth, she still takes care of Wan Wan in her behavior." Wang Wenyan rubbed his hands. "That family is a little depressed. There are a lot of rules in the family. The whole family is in charge of Wan Wan's grandfather. The old man is very strict and has a lot of tutors. His eyes can't contain sand. Wan Wan's father has a bad temper, and sometimes he'll beat his children when he's angry. "This is a traditional family. Men are in charge of most of the housework and labor in the family. Men are in charge of major events. Domestic violence happens from time to time. A young girl suddenly loses her mother's care. In such a family, although Wang Wenyan does not have a specific description, it is enough to make people think of what they have experienced.

Song Wen slightly frowned: "at that time, Lin wanwan was still very small? Don't you care to leave your daughter? "

Wang Wenyan nodded: "the child of my own family is naturally distressed. When wanwan was ten years old, I finally wanted to open my mind and divorced the man."

"So during that time, were you and your daughter living together?"

"It was a little difficult for us to say that our mother and daughter were dependent on each other. Two years later, after graduation from wanwan primary school, I was introduced to marry the man I am now."

Song Wen read the information, Wang Wenyan's husband surnamed Li, high school education, is a long-distance bus driver, resume is very simple, every month hard-working, the wind and the sun, but the salary has not been high.

"Later, I gave him a son, and he grew up. He studied very well, won the examinations and went to university. This is the pride of our family. Over the years, I have been towards her, although she is a girl, in my side, has not suffered She took her daughter to her side and responded to her request as a compensation for her daughter's childhood misfortune.

"After Lin wanwan junior high school, are you taking care of her in her daily life and study?"

"Wanwan is a smart kid, and I haven't been bothered. I am a person who has achieved nothing since I was a child. I am not good at learning and learning. I have no long time to do many things. When I am young, I do not read well and I am not sensible. When I meet a man, I often say to Wan Wan, "you must not become a man like my mother. You must have a better life."

When it comes to the topic of educating children, Wang Wenyan suddenly finds a topic. For a housewife like her, children are her best report card. Especially, there is a daughter who is so clever and obedient as Wan Wan Wan and has good grades. How many people envy her. Her ordinary life, also has a flash point, has a place to be proud of.

Song Wen continued to ask: "after wanwan went to university, didn't he often go home?"

Wang Wenyan's interest in being picked up was dim. She smoothed her hair with her hand to relieve her embarrassment: "she is very busy with her studies. She is still working outside. We have paid tuition fees, but we don't give much for living expenses. But as long as she says that she is short of money and sells iron through a pot, we will call her back." Then she sighed, "it's a shame to have such mediocre parents as us."

"Did Lin wanwan say how she lived at school and how did her roommate relationship go?"

"Wan Wan said that she was very good at school. The teachers and classmates took good care of her. I have seen several children in their dormitory when I delivered things to wanwan. They all look good children. How could..." Wang Wenyan sighed with some regret, "I remember there was a child who was very tall and beautiful, and then there was a very white one. It seemed that the family environment was good."

"She also has a classmate named Guo Zhen. Have you met her

"I'm also impressed with the child surnamed Guo, but I haven't heard much about it." Wang Wenyan said and smoothed her hair.

Lu Siyu frowned slightly, thinking about what kind of "friends" Lin wanwan and Guo Zhen were. Before Song Wen continued to ask, he raised his eyes and looked at the woman's rough hand: "when Lin wanwan was at home, did you usually do housework?"

The woman nodded, as if it was a matter of course to serve the family's children and husband: "I do cooking, washing dishes, washing clothes and cleaning. The children are busy at school, and my husband is busy working. He is not at home all year round and makes hard money." Then she sighed, "police comrade, my cable is no problem, this time it must only be associated, she is a obedient, kind-hearted girl."

Lu Siyu recorded these things, biting his pen cap and lowering his head to think, some of the information seemed to be different from the clues they had known before. Although Lin wanwan was not from a good family, she was actually a pretty girl from a poor family. She was beaten and severely punished before she was ten years old.

Song Wen asked some regular questions. Wang Wenyan answered them one by one. After looking at the time, Song Wen got up and said, "can we have a look at Lin wanwan's things?"

Wang Wenyan led them to the children's room, where there were two beds, one with guardrail and the other without. Obviously, the one with guardrail was for Lin wanwan's younger brother to sleep.

The boy was still young, and Lin wanwan went out of the exam again. There was a cabinet in the room. There were several layers of girls' things in it, and the other layers were boys' things. The windows were clearly divided. Lin wanwan put them in order. Her brother's was a mess, and the things could not be put down. But what's amazing is that even if it's dirty and messy, his brother's My brother didn't pile things up in the unfilled space of Lin wanwan.

Wang Wenyan explained: "Wan Wan is not at home now, but we have never moved her things, and her brother dare not turn over her things."

Song Wen probe to see, there are some books, textbooks, homework books, and several world famous works.There are dolls in the cupboard. They are the kind of Barbie dolls bought in shopping malls. There are four or five sets of dolls in a set. They are bright and beautiful. They don't match the style of the whole room. Song Wen sees a box inside, which is the kind of biscuit box in the past. He reached out and opened it. Inside, there was a box of chocolate candy paper full of colors and colors, which were folded into a dancing girl. He had seen Lin wanwan fold this during interrogation and raised his head to ask Wang Wenyan, "is this

Wang Wenyan: "this box was brought by Wan Wan when he came from his father. Although my ex husband beat and scolded her once in a while, he often bought candy for her. Later, she came and asked me for sweets occasionally. I also bought them for her, so I saved such a big box. "

After reading the bookcase, Song Wen and Lu Si Yu rummaged around the room again. There were some old clothes, nothing special.

At this time, the door was suddenly kicked.

After hearing this voice, Wang Wenyan's face changed. He ran to open the door in a panic. As soon as the door lock was opened, he was knocked open from the outside with great efforts, "Ma! Did you forget to put my PE shoes in my schoolbag again With the voice, running in from the outside, a little boy of about ten years old, well-developed, a little fat, looks like a small adult.

"Do you have PE today? You didn't tell me in advance? " Wang Wenyan stood aside and rubbed his hands a little awkwardly.

"I said! I've said it for a long time. Besides, we are at this time every week. We have been in school for more than two months. Why don't you remember that? " The boy ran to the door, picked up the cold cup on the table and gulped it down. Then he found that there were more guests in the house. He looked up at Song Wen and Lu Siyu, "what do you do?"

Song Wenzheng was about to speak. Wang Wenyan winked at him and said, "it's the teacher of your sister's school. Come to visit and ask about your sister's family."

The boy is Lin wanwan's younger brother, Li Zichen. He is nine and a half years old. Although the two brothers were born to one mother, they had different fathers and even different surnames. Li Zichen's eyes turned and asked, "what's wrong with my sister?" When a boy is about ten years old, he is half understanding.

Lu Siyu didn't break Wang Wenyan's lie, and said, "there is a place for exchange students to go abroad in the school. Let's do a home visit."

Li Zichen nodded: "Oh. My sister studies well, and the quota must be given to her. "

Seeing Li Zichen here, Wang Wenyan didn't seem to want to ask any more questions. He took out an orange plate from the kitchen and said, "it's all back. You can go back later and eat an orange." As she spoke, she thrust the plate in front of the child.

Unexpectedly, this action attracted the child's disgust. He reached out and pushed Wang Wenyan. Wang Wenyan's body fell back, and the orange on the plate rolled to the ground.

Li Zichen said, "I don't eat oranges. I want my sneakers. I have an appointment with them to play football. You always forget things and can't do anything well. It's useless. No wonder my sister doesn't want to go home. " He was not afraid of his sister's school teacher or who was standing in the living room.

Wang Wenyan sighed. He got up and picked up some oranges. Then he went to the balcony and picked up a pair of washed shoes. Li Zichen stamped his foot and said, "you haven't tied the shoelaces yet!"

Wang Wenyan had to sit on the sofa again and put on the shoelaces, and Li Zichen ran back to class contentedly. After seeing off the child, Wang Wenyan turned to look at Song Wen and Lu Si Yu. He seemed a little embarrassed and said, "this child is spoiled by me." She laughed as she spoke, as if she didn't think it was an embarrassing thing at all, but a natural normality in her life.

Song Wenyi said with a smile: "children."

Looking at this side, they almost asked each other. They got up to leave and came out of Lin wanwan's house. Song Wen looked at the time and said, "we still have some time. Do you want to ask the neighbors or something?"

Lu Si Yu nodded: "her mother can't believe everything she said. There are some doubts in this family..."

Two people have just said this, suddenly from the front of the intersection to jump out of a red collar, full of white hair old lady, a pair of eyes straight, staring at the thief general look at them: "you two, sneaky, who are you?"

Song Wen was startled by the sudden appearance of the old lady. The old man was completely silent and suddenly jumped out of the wall. His posture was extremely dexterous. He hastily took out the document: "we are the police, come here to look for." He looked at the old lady again. "Are you?"

The old lady pointed to her red sleeve hoop. She was very proud and justifiable: "the director of the neighborhood committee in my area, why don't you say hello to our neighborhood committee when you come here? Who let you in? It's against the rules! " The old lady took Song Wen's certificate and looked at it suspiciously. She had a very strong sense of prevention. She looked up at him and folded her drooping eyelids. "How did the police in Nancheng come to our Qincheng?"

Song Wen thought, you don't even have a concierge here. Who knows, he is so strict. He is patient and explains simply: "Auntie, we have a case in Nancheng. One of the relevant personnel is related to this side. So we came to follow up and went to 403 units of three units.""Oh, you go to Lin wanwan's house." Obviously, the old lady was very helpful to her aunt, so she returned her certificate to Song Wen.

Song Wen and Lu Siyu did not expect Lin wanwan to be so famous, so they exchanged their eyes. Song Wen took back his ID card and asked her casually, "yes, it's their family. We just went to see Lin wanwan's mother. Do you know Lin wanwan? "

the old lady gossiped:" that girl is good at studying. She is famous in our town. This is only a senior. If she had not been implicated by her mother, the matchmaker would have broken the door. Is something wrong with the girl

Now that the case is still under investigation, Song Wen is not willing to disclose the details: "she didn't have an accident, it was Lin wanwan's classmates who had an accident. Let's come to understand the situation."

"Oh, well." The old lady showed a look of No gossip and a little disappointment. She didn't think about it carefully. Why did they come to Lin wanwan's house for a follow-up visit.

"Auntie, do you know their family? You just said that Lin wanwan was implicated by her mother. What's the matter? " Song Wen asked, generally this kind of old people go through the streets, know a lot of news. It took eight hours to come back and forth from Nancheng. Some things had to be seen before they could be judged. The suspects will lie, and the parents and relatives around them will whitewash the peace. He hopes to hear a different voice from these neighbors.

The old lady began to talk about these things and said, "well, yes, Xiao Wang of that family used to be a shelf member of the small supermarket here. Because he always made mistakes, he was opened up and stayed at home all the time. Speaking of it, this family is very lucky It was the winter vacation three years ago. We haven't changed natural gas here. Every household is gas. Xiao Wang is at home, Xiao Li hasn't gone out to drive. His second son is also at home. Lin wanwan gets up early and goes to the library to read and study. Later, the neighbors smelled gas in their house and called the police. Police, fire and first aid are all here. The family was in a coma at that time. They were sent to the hospital and stayed for a few days

In such a small town, it's big news that a family nearly died of gas poisoning.

The old lady would also cheat: "later, you can guess what happened. Xiao Wang got up in the morning and burned the water, but later she felt cold and went back to the bed and fell asleep. The water boiled and put out the fire, and the family almost lost the gas. Fortunately, the girl Lin wanwan was so lucky that she went out early. Otherwise, she would have to follow the bad luck. But as soon as this incident happened, no one came to the door to offer matchmaking to Wan Wan. After all, no one was afraid of such a mother-in-law. "

Lu Si Yu frowned: "is this what Wang Wenyan said?"

The old lady said, "Hey, you're still a policeman. There's no one who knows this by himself."

Song Wen strange: "you said the police are here? Why didn't you check your fingerprints? Do some research? "

"There is a relative of my family who belongs to the Public Security Bureau. At that time, this matter was very strange. It had been checked and there was no fingerprint, so it was even more strange. Anyway, Xiao Wang said that she didn't boil water, but the water would not go to the gas itself. Her husband, son and daughter all confirmed that she did it. Later, she recognized it. Because there was no dead person, it was not settled. The family changed the gas stove that prevents leakage, just dare to let her continue to cook The old lady spoke vividly, as if she were the one who handled it, and knew every detail.

Song Wen frowned and looked back at the window of Lin wanwan's house. Then he looked back at Lu Siyu, who lowered his head and habitually bit his nails, as if thinking about something.

Then the old lady gossiped again and said nothing of value.

At first, it was the old lady who chased them to provide clues. Later, they chased the old lady to ask about the relevant information. The old lady became impatient and looked at her watch frequently. "Oh, I've said everything I know. I'm going to buy vegetables to pick up my grandson." Song Wen then let people go.

Lu Siyu turned his head and looked at Song Wen. Song Wen immediately understood and said, "let's go to dinner first. We'll hurry back and ask other people what's going on there."

This small town is not very big. They choose a small restaurant to sit in. Song Wen orders. Lu Siyu asks for someone to heat the food he takes out.

It can be seen that the Lushi language has been forced to a certain extent, and even the food has become a quick fried egg with tomato, diced chicken, mushroom, fried sea crab with scallion and ginger. The food is simple, but the ingredients are fresh. The tomatoes are peeled, and the crabs are clean. Even the crab clips are cracked and fried to taste. The dishes cooked by the master of this small restaurant are not small in taste, but they are saltier one by one. Song Wen finally rubbed the dishes in the Lu Si language lunch box and ate them with rice.

Just after dinner, Fu Linjiang called. Song Wen plugged in his earphone and used the one with a headset, and handed it to Lu Si Yu at the other end. Fu Linjiang's voice said, "we have some new discoveries here. It was not Ma Aijing who ate with Dong Fang and went shopping with Dong Fang. Sometimes it was Lin wanwan. We found a small video of the supermarket downstairs of the school dormitory. Dong Fang swiped his card there. Lin wanwan opened the package directly and ate it without sight. " Today, they went to the school to make up for the omissions. All the available materials were retrieved. As expected, some details that were not found in the initial survey were revealed."And ha, Ma Aijing did have an affair with their professors, but the professor said that she just asked him to give extra points on the paper scores. As for the overseas exchange, Ma Aijing was chosen because the exchange students required good English and good image. Ma Aijing is more in line with this, which they have said to Guo Zhen for a long time. At that time, Guo Zhen was very calm and had no objection. The paper that Ma Ai Jing scored was co authored. Guess who the other author is. "

Song Wencai: "Lin wanwan?"

Fu Linjiang exclaimed, "how did you guess it?"

Song Wen hummed: "you let me guess, of course, it's not Dong Fang's, it won't be cooperation with Guo fan."

Fu Linjiang also mentioned some situations, and the main theme was one. In their reasoning at the scene of the crime, they thought Lin wanwan was free from the bedroom. Now it seems that her relationship with other people in the bedroom is much closer than what they initially deduced.

"Anyway, she spent Dong Fang's money and enjoyed Ma Aijing's paper bonus points. She was very comfortable, and she didn't feel so miserable when facing us. Besides, we checked the video. Lin wanwan helped to get the box of chocolate back to the dormitory that morning. I also tend to think that Lin wanwan has something to do with it. She went to the express delivery point to pick up the chocolate and came back. She also knew that Guo Fen had the remaining poison and had enough time to commit the crime. However, no motive has been found. "

"Any progress in other areas?" Song Wen asked again.

Fu Linjiang said: "the museum is still checking those chocolates, but they also have a problem. The chocolate has no name. It can only prove that chocolate has been dropped everywhere. It's not clear who left the traces. "

Song Wen was a little helpless, but he could only accept the result: "OK, I know about these. You can continue to refuel and wait for me to collect."

Fu Linjiang hung up the phone, and Lu Siyu took off his earphone and said, "I found out before that the relationship in the dormitory may not be as simple as we seem. On that day, I felt that Lin wanwan was too clean there. Then I figured it out... "

Song Wen thought about it and immediately understood the meaning of Lushi language: "what we see is what others want us to see. What we ask is what others want us to ask. "

After saying this, Song Wen's eyes fell on Lu Si Yu, and he remembered Zhou Yining's conversation with him before. It seems that this sentence is also suitable for the use of Lushi language.

However, Lu Si Yu did not find the difference in Song Wen's eyes. He lowered his head and said, "we don't know what the real relationship is in the dormitory."

Some people have cleaned up the dormitory. Before the police arrived, maybe there was a premeditation a few days ago. In particular, Lin wanwan was very clean. It was this cleanliness that made her special.

Song Wen sighed: "the relationship between these people is more complicated than we imagined." It's not the same case that they've been dealing with in the past. In the beginning, they underestimated the complexity of the case, but in retrospect, the whole story may be more complicated than they thought.

The two men came out of the small hotel and walked all the way along the streets of strange cities. The roads here are narrower than those in the south. There are tall evergreen plants on the roadside. Now they have just sprouted. Song Wen is not in a hurry to take a taxi. He turns to ask Lu Siyu, "what do you think of Lin wanwan's family?"

Lu Siyu didn't answer Song Wen. He blinked and asked him, "what do you think?"

Song Wen thought for a moment: "Lin wanwan's family is different from what I thought before. I thought her parents were indifferent and bad to her, which formed her gentle character. But unexpectedly, her family is like this. Her mother dotes on her, her stepfather is honest and honest, she is absent all the year round, and her younger brother is rude and unreasonable, but she also attaches great importance to her sister. This family looks like a happy family. But I always think there is something wrong with it. "

Lu Si said with a cold look on his face: "happy family? A mother with a bad memory, a father who is not at home all the year round, a reckless younger brother, and a sister suspected to be a murderer. The gas poisoning that nearly killed the family once is a model of a horror story. "

Song Wen clearly understood a truth. When different people look at the same thing, their perception may be completely different. All this is also related to his life experience. As a criminal policeman, he has always been more than upright. This kind of integrity can make him stick to his justice more, but it also makes him unable to understand the abnormal world in which the criminals live Dark place, to find out their twisted hearts. In short, he is a normal person, unable to think with abnormal thinking, do not know what the abnormal is thinking.

And the Lushi language But it's as if it's easy to see through what they think.

Just like at this time, he just felt that the family was not right, but he didn't know what was wrong. All this was totally different in the eyes of Lu Si language. When he said this, Song Wen suddenly realized: "do you think that gas poisoning was not an accident?"

There was a murmur of Lusi.

Song Wen got up and said, "is it an accident? Let's go and ask."

Lu Si language a Leng, "you want to investigate this matter?"The vigorous song team took the initiative to help him carry the bag: "all come here, at least listen to what the parties say. Let's go to Lin wanwan's house and kill a bullet."

It's only a step away from finding out the truth.
