Wang Lei smiled faintly and said, "Director Zhou, it's unlikely that it has nothing to do with you. The last time I was here, I wondered why you had a large single picture of the kids hanging outside, all wearing only a little dress or short skirt. Of course, I guess you can interpret this as a picture of the children's art or dancing. But who would hang a picture of a child who isn't their own in the bedroom and at the head of the bed, right? Hehehehehehe"

"Look at the pictures in your bedroom for yourselves, and if nothing else, it's a bit explicit. You said that Yu Cheng likes children, you are so young, why aren't you in a hurry to have one? So at the time, I suspected that you had some psychological problems. ”

"Not to mention that I took advantage of your lack of attention that day to look at the dishes in your TV cabinet, which are full of the kind of child-molesting DVDs from abroad. You said that the empty space above the head of the bed used to be a photo of Xu Qinya, and I believe you are telling the truth. Yu Cheng took it down after killing their entire family, am I right? ”

Yu Cheng lowered his head and panted heavily, Zhou Chunyan was a little frightened, the last time he asked him to visit, he thought it was just like those parents before, but he felt that he cared about the children here.

Mao Qiang stood stupidly holding the things in his hands, there are still not many cases of this kind of psychopathology in China, and everyone is so surprised that they don't know what to do. Li Li looked at the two suspects and asked Wang Lei, "Then how did they kill the Xuchang family, fat man?" ”

Wang Lei pointed to the bedroom window and said, "Didn't you find it?" It is just a wall away from Block 172. When everyone came to the window, Liu Xiaolin pushed open the window, and there was a wall at a distance of one meter. Less than two meters on the opposite side of the fence is the building of the Xuchang family, and the window here is basically diagonally facing the kitchen of the Xuchang family. In general, due to the smoke in the kitchen, the screen window is closed at most, and the glass window is open. There is a long wooden board erected on the wall under the wall here, which means that when Yu Cheng opens the window at home, he can pull the wooden board up, put it on the wall and pass it in a few steps.

Generally, it is not for special reasons, and people rarely go to the back of the building, not to mention that some people will throw garbage at the back of the building, so that people rarely go to those places.

On Chinese New Year's Eve, everyone stays in the bedroom or living room to watch TV, and firecrackers are set off in the courtyard of the community or on the street outside. The kindergarten building and the building in Xuchang are back to back, the street lights will definitely not be there, and a large number of firecrackers will also cover up some of the sounds of climbing over the wall Zhou Chunyan began to sob, "The two husbands and wives in Xuchang know what Yu Cheng did to Xu Qinya, and they threatened us and asked us to come up with 500,000 yuan as compensation, otherwise we would call the police." There's really nothing we can do to do that, we ......."

Li Li felt very disgusted, "Zhou Chunyan, do you know that Yu Cheng's behavior is not reported and he is still helping him do bad things, you call it aiding and abusive, understand?" You can rest assured that there is a place for you in the prison. ”

Mao Qiang took out a small tape recorder, opened it and placed it in front of Zhou Chunyan, and said in a deep voice, "It's not impossible for you to be a little more relaxed, and honestly confess all your knowledge of the Tao, and it will be regarded as your meritorious service, um!" ”

Zhou Chunyan looked at Yu Cheng and gritted her teeth, the husband and wife were originally birds in the same forest, and they flew separately when the disaster came. It's no wonder that I am ruthless, I don't want to die, "Yu Cheng and I are middle school classmates and have been in love for many years. I didn't know about his quirks that I discovered by accident last year. Because the children are all in their own kindergartens, they don't dare to say anything, and Yu Cheng often beats and scolds me, or threatens to kill my whole family, and I have no choice. But I didn't get involved in his affairs, I just helped to appease the little girls who were molested by him. Officer, I really wasn't involved. ”

Mao Qiang remained silent at all, Wang Lei crossed his arms and looked out the window, listening to Zhou Chunyan's self-description.

"Yu Cheng molested Xu Qinya a few years ago, Xu Qinya told his parents when he went home, and his parents came to the kindergarten, and I knelt down to ask them for forgiveness. I promised to give them 500,000 yuan as compensation by Chinese New Year's Eve at the latest, and they took the child home the next day. But I couldn't scrape together so much money, and seeing that the deadline was up, I persuaded Yu Cheng to turn himself in, but he didn't agree, saying that he would solve it. ”

"In the middle of the night on Chinese New Year's Eve, he climbed the wall, and he said to threaten the Xuchang family, and I believed it. He came back covered in blood, and the next morning I found out what he had done......"

With Zhou Chunyan's narration, the facts of the case gradually became clear in the eyes of everyone. Yu Cheng climbed in from the kitchen, and the first step must be the living room, which is also the reason why Xu Chang in the living room was the first to be killed. Thinking that the Xuchang family should have called for help, but it was covered up by the sound of firecrackers one after another.

Mao Qiang kicked Yu Cheng, "Why are you stabbing Xu Qinya 7 times in a row?" For what, say!! ”

Yu Cheng still lowered his head, and only replied after a long time, "If she hadn't told her parents, if her parents hadn't asked us for compensation, how could I have killed someone!" Everything is fast for her!! I hate her!! ”

Li Yuan really couldn't control it, grabbed Yu Cheng's hair, picked it up, and punched him hard in the face several times in a row, "You fucking scum!" You still have a 6-year-old kid with a face weirdo! You're going to hell with a thousand cuts! ”

Mao Qiang turned off the tape recorder with a "click", as if he didn't see Li Yuan's behavior, "I'll call the Land Bureau to report the success, you pay attention, the suspect is very cruel, arrested!" ”

Mao Qiang walked out of the room, several people rushed up, punched and kicked, Yu Cheng's face was suddenly red and swollen, Li Li directly kicked through the crack of the person, kicked Yu Cheng's face, Yu Cheng's nosebleed gushed out, Wang Lei clapped his hands, "It's almost, the arrest has been subdued." ”

Half an hour later, two cars slowly drove into the gate of the Public Security Bureau, and in the foyer, Lu Haitao and the middle-level cadres in the bureau were already waiting there. As soon as Mao Qiang and Li Li got out of the car, the warm applause around them suddenly rang out. Liu Xiaolin walked behind the most, dragging the dying Yu Cheng, and Lu Haitao still looked over. Mao Qiang whispered, "The suspect was arrested and almost killed Li Li, but fortunately he was saved by Wang Lei, so everyone was a little heavier." Hey, hey, hey, hey, hey"

Lu Haitao nodded knowingly, "Come on, throw it in and look at it tightly." Everyone washed up and hurried to the cafeteria, and the celebration wine had been arranged for you. Later, the leaders of the city will come, and they will also visit all the members of your serious crime team, Mao Qiang, you have to speak, go and prepare. ”

Taking advantage of Li Li's few face-washes, Wang Lei pulled Mao Qiang aside, "Team Mao, I won't go to the cafeteria, I don't want to go to those occasions." You bring me all of Lin Long's files, and I'll take them home and take them back tomorrow morning." ”

Mao Qiang paused, nodded and agreed, "Okay, you come with me, I'll give it to you, it's just that there are a lot of files, I'll get you a cardboard box." Remember to take it all back tomorrow, you also know that according to the rules, the file cannot be taken out of the file, your situation is special, except once, this is also the reward you should get today. ”

Wang Lei sat in the office, the festive laughter outside could be faintly heard through the window, picked up the photo on the table that was as brilliant as a summer flower, turned it over, found a screwdriver in the drawer, opened the photo frame, put the photo into the inner bag, and pressed it close to his heart. Looking left and right, Wang Lei casually threw the empty photo frame into the trash.

After sitting for a long time, the sky outside was dark, Wang Lei hugged the cardboard box, left behind the building, the canteen, and all the hustle and bustle, and from then on, he could only go home alone.

It was still that corner, the corner of the bed, a table lamp was pulled, and the light was adjusted to be very dim, Wang Lei sat on his knees against the wall, a large pile of information was scattered on the ground, Wang Lei looked intently at a forensic examination report in his hand.

This is already the second time I have watched it, and there is not the slightest clue. Wang Lei rubbed his temples, got up and went to the kitchen, there was nothing in the cold kitchen, Wang Lei didn't care, he turned his head and opened his mouth directly, turned on the faucet, poured a stomach of cold water, rinsed his face by the way, and returned to the corner to sit down.

lit a cigarette, and under the dim light, Wang Lei's little eyes narrowed slightly, and he silently read the materials word by word. It can be seen that although the time is very short, the materials collected by the serious crime team are quite complete. It's just that......

There is no trace of any outsiders; police officers and auxiliary police officers of police stations, excluded; Passing traffic police, excluded; Criminals who have been caught by themselves, excluded.

Elimination, exclusion, exclusion, Wang Lei's mind flashed a series of exclusions. It's the last material I've read for the third time in my hand, even if I close my eyes, Wang Lei knows the content of the Dao, and it should still be excluded!

Returning the materials on the ground to the cardboard box, Wang Lei lit the cigarette again, and there was no trace of it? Who will leave no trace? Wang Lei believes that in addition to himself, even if the rest of the serious crime team, including Mao Qiang, commits crimes, I am afraid they will not be able to do it to this extent, at most they will leave few traces in places that are not easy to find.

Who has such a masterful means? A professional killer? Hehehehe, there is no professional killer who comes back to kill a housewife. Lin Long's former boyfriend? Suitors? No, no, the fat man shook his head, Lin Long's first love is himself, his first love is Lin Long, where did he come from! Robbery and theft have long been ruled out. Neighbors, hehehehe, the neighbors are all elderly, the main reason why he and Lin Long decided to buy a house here is that there are more elderly people, Lin Long likes to accompany the elderly and communicate with children, this is also excluded.

Then, there are actually very few people who can do it, and they should actually know the Tao. The fat man's fingers holding the cigarette trembled, what should he know about it? What do you know?

Suddenly, Wang Lei snuffed out the cigarette in his hand, turned the carton over roughly, poured out all the materials, and pulled wildly with his hands, looking for it.

A piece of paper came into Wang Lei's eyes, the fat man's whole body began to tremble, stretched out his trembling hand, and picked up the piece of paper very softly, very good, the piece of paper did not disappear suddenly. Facing the lamp, the words on the scrap of paper are clearly visible......
