Criminal Investigation Chronicle

Zhao Lei looked at the inspection report, immediately got up and left the police station, and drove to the small shop where he bought water in the morning.When he came to the small shop, Zhao Lei found a bucket of laundry detergent of the same brand as Liu Changan bought, and took a few buckets of other brands, and rushed back to the police station for testing.

After testing and comparison, the detergent extracted on-site was exactly the same as the laundry detergent purchased by Liu Changan.

Zhao Lei reported his deduction to Li Liang, the deputy captain. After police analysis, he believed that Liu Changan might be suspected of committing the crime. "Immediately apply for an arrest warrant and arrest Liu Changan."

Next, the police found Liu Changan smoothly. Liu Changan had just sent his boss home, and he had dinner not far from the boss's house.Liu Changan is a private car driver who drives for his boss. He has a relatively fixed job every day and is easy to find.

In the interrogation room, Zhao Lei interrogated Liu Changan.

Zhao Lei: "Name, age, occupation."

Liu Changan: "Liu Changan, 26 years old, private car driver."

Zhao Lei: "After 6:7 p.m. on June 6, where and what did you do? Can anyone prove it?"

Liu Chang'an: "At 6:7 p.m. on June 6th, I sent my boss home, had dinner by myself, watched TV at home, and fell asleep after 10 p.m. But I live by myself, and no one can prove that .”

Zhao Lei: "From 6:8 am to 5:7 am on June [-]th, where, what, who can prove it?"

Liu Chang'an: "On June 6th, I got up at 8:6 a.m., washed up, had breakfast, then went to buy laundry detergent, and ran into you, the police officer."

Zhao Lei: "Why did you buy two buckets of laundry detergent in a row? Where are the two buckets of laundry detergent now?"

Liu Chang'an: "The laundry detergent I bought this morning is still in the boss's car. I bought the bucket yesterday and forgot it in the restaurant. I have some clothes to wash at home, so I bought another bucket."

Zhao Lei: "Do you usually wear gloves?"

Liu Changan: "It's about the same. I usually take it off at home, and I wear it when I'm afraid of scaring others outside."

Zhao Lei: "Do you know Xiaoyang?" Zhao Lei showed Liu Chang'an a photo of the deceased Xiaoyang before he was alive.

Liu Changan picked up the photo and looked at it for a few seconds, then said, "I don't know, except for going to work and eating, I just stay at home and rarely come into contact with children."

Zhao Lei: "Do you have a girlfriend?"

Liu Chang'an shook his head and said, "My family is not good, and I work as a migrant worker. Although my income is decent now, I'm just a driver and my job is average. Girls don't like to associate with me."

Zhao Lei asked again: "You are so handsome, and no one likes you?"

Liu Changan smiled shyly: "My job is to pick up and drop off the boss, and I seldom deal with the opposite sex."

Zhao Lei felt that if he continued to ask, he might not be able to find any useful clues. He needed to start with Liu Changan's interpersonal relationships, activities, life patterns, and family background.

The police officers who came back from Liu Changan's home investigation said that, as Liu Changan said, there were a lot of clothes piled up at home, and an unopened bucket of laundry detergent was found in Liu Changan's boss' car.Liu Changan’s background is very simple. He graduated from high school. His hometown is Hunan. He has worked in Yanjing for four years. Nothing special.

Zhao Lei lit a cigarette, and his thoughts were a little confused. Judging from the circumstances of Xiaoyang's murder, the murderer should be a ruthless, cold-blooded pervert, but Liu Changan gave him the feeling that he was too ordinary, maybe Liu Changan was good at disguising, so far , There is no evidence at all that Liu Changan is the murderer, and it cannot be concluded that he is a murderer just because he bought a bucket of laundry detergent.Zhao Lei checked the time, greeted his colleagues, and rushed to the police academy.

Went to the police academy to find Lin Chong, Zhao Lei described the case to Lin Chong in detail, Lin Chong was very angry when he heard the cruelty of the murderer, calmed down and began to analyze, said: "Brother Zhao, from your description, I also think there are several key points in this case. One is what Xiaoyang's parents said, that Xiaoyang has a cute personality and looks like a girl. The second is that Xiaoyang's genitals were cut off by the murderer. Judging from criminal psychology, the murderer is likely to have a mental illness such as transsexualism. Xiaoyang’s girl-like personality stimulated the murderer. The murderer cut off Xiaoyang’s genitals and left a doll, which is a hint, such as It means that the child Xiaoyang should be a girl, and so on. The murderer should be very sensitive to gender, or have a pathological obsession with gender. Did you find women's clothing in Liu Changan's house? I think the murderer may have cross-dressing addiction."

After Zhao Lei heard this, he thought about it for a while, and said, "There is nothing special about Liu Changan, and his family is also normal. It may be that he hides too deeply, but at least there are no clues."

"If there is no progress, when will Liu Changan be released? Tell me before releasing him, I have an idea."

Zhao Lei didn't ask Lin Chong what idea he came up with, but replied: "If no evidence is found, he will be released at 1 o'clock tomorrow afternoon."

Zhao Lei returned to the police station, just after lighting a cigarette, Liu Changan's boss came.Liu Changan's boss is Xu Jiazhe, an executive of a large company. He is in his forties, with a medium build and an extraordinary bearing. He is quite similar to a star who often plays the role of emperor.Zhao Lei looked at Xu Jiazhe, and talked to him about Liu Changan: "Mr. Xu, what do you think of your driver Liu Changan?"

Xu Jiazhe said: "The kid Changan is very down-to-earth, has no bad habits, works hard, and has never had any accidents while driving."

Zhao Lei: "How did you know Liu Chang'an?"

Xu Jiazhe: "I came to Yanjing four years ago. At that time, my former driver was sick and hospitalized. I posted a recruitment notice. Changan came to apply when he saw the recruitment notice. I thought he was young and didn't want to hire him at first, but his family The conditions are not very good, and I am in a hurry to spend money. I saw that his driving skills are good, so I wanted to try it out for a month. After a month, I think he is really a good guy. Let him be my driver."

Zhao Lei: "Has Liu Changan behaved abnormally recently?"

Xu Jiazhe: "No, Changan has always been very law-abiding. I treat him better than ordinary drivers, and he is very grateful. In short, I think you have made a mistake. Changan is kind-hearted, not a vicious person."

Zhao Lei smiled and said, "Don't worry, Mr. Xu, we won't wrong good people. If Liu Chang'an is innocent, he will go out soon after he assists in the investigation. But if he really committed a crime, we will definitely release him." He has been brought to justice. Thank you for your cooperation."

Xu Jiazhe didn't say anything else, looked at the time, got up and left.

Zhao Lei suddenly called Xu Jiazhe to stop, and asked: "Mr. Xu, do you know that Liu Changan has always been single? Why doesn't he have a girlfriend? I think he is quite handsome."

Xu Jiazhe replied: "I know that Chang'an is single, and I also asked, why don't you find a girlfriend. Chang'an said that he was going back to his hometown to find a girlfriend, but he didn't say anything specific. I'm not easy to ask about this kind of personal relationship."

After sending Xu Jiazhe away, Zhao Lei wrote on the paper: single handsome guy.

At around 6 noon on June 9, Zhao Lei smoked at the entrance of the police station and looked at his watch. It was time to release Liu Changan soon.Zhao Lei felt a little helpless, but he had no evidence, so he had no choice but to let him go when the time came.At this time, a person came to face him, it was Lin Chong, but Lin Chong's appearance surprised Zhao Lei. Lin Chong was wearing a wig, lipstick, face powder, and high heels. Wearing a dress, but Lin Chong has a strong figure. He is 12 meters tall and wears high heels, which looks completely nondescript.Zhao Lei took a deep puff of cigarette and asked, "I said brother, which song are you singing?"

Lin Chong smiled at Zhao Lei and said, "Brother Zhao, according to my reasoning, if the murderer really has transsexualism or transvestism, he will definitely have a special reaction when he sees me like this."

At 1 p.m., Liu Changan was released because no strong evidence was found.Liu Changan walked out of the police station, passing by Zhao Lei and Lin Chong at the door, Lin Chong twisted his waist, walked into Zhao Lei and said, "Officer, give me a cigarette." The voice was pretentious, and Zhao Lei was very cooperative and handed out a cigarette, Give it back to Lin Chong.Liu Changan curled his lips and glanced at Zhao Lei and Lin Chong, then pointed to Zhao Lei, left Zhao and Lin, and said as he walked, "What the hell."

When Liu Changan walked away, Lin Chong shook his head and said to Zhao Lei: "Brother Zhao, I don't think it's him. His reaction is too normal, just like other passers-by's reaction, disgust and contempt, this is a normal person's reaction. If it is a murderer , He will definitely show some other emotions, such as excitement, surprise, hatred, ferocity, etc., which I have not captured. Some things can be disguised, but some things cannot be faked."

Zhao Lei didn't express his opinion, but sent someone to watch Liu Chang'an.
