I don't want to solve the case when I'm a little policeman.

Chapter 863 He is just a child

I thought there was a turning point in the case, but the subsequent investigation gave everyone a blow.

The AI ​​couple development game that Du Meijuan played ten years ago was discontinued five years ago, because this game was self-developed by a company, and discontinuing the game means it will be delisted.

When they ran the game, they rented servers and were a small company. The games they subsequently developed were incompatible with the AI ​​couple development game.

Therefore, all game user data will be deleted after the unspent recharge coins are returned to the user.

In this case, it is impossible to investigate what Du Meijuan and Song Hao did in the game.

"Bamboo green, sky stone." Xu Zheng was not discouraged, but changed his mind, "You two immediately contact Du Meijuan's relatives and friends recorded in the file to see if you can pass these people.

Try to recreate what she did in the game.

Pay special attention to whether she has been in love or married with a certain netizen in the game. "

Previous task forces have investigated the relatives, friends and customers of Du Meijuan and Song Hao, including netizens such as WeChat Moments and Douyin.

Xu Zheng’s current investigative idea is very simple. Since the police have already investigated those people offline and online, the case file does not include a large-scale investigation of Du Meijuan and Song Hao’s game friends.

So is it possible that the murderer is hiding among them?

Xu Zheng thinks this is possible. In games from ten years ago or even longer ago, in addition to competitive games, PC and web games also had marriage function sections.

Although it is a game, some people with paranoid personalities have different cognitions from normal people.

They will think that marriage in the game equals reality.

In this case, there is a possibility that one of Du Meijuan's netizens met her in real life, and then learned about her real identity and work, and thought that she was emotionally cheated.

So this netizen thought that Du Meijuan put many hats on him.

Then he held a grudge, and finally planned the murder of Du Meijuan after Song Hao died in a car accident.

Xu Zheng thought of this and scratched his head in distress. If the truth was true, it would contradict their previous thoughts. They originally believed that this case was a gang crime.

If the murderer is a radical person, then there is a high probability that only one person will commit the crime.

Besides, these days, no matter how good friends are, even father, son and brothers, it is impossible for them to form a group to kill Du Meijuan for this matter.

Mr. Yan watched Xu Zheng and Zhu Qing fall into deep thought after giving instructions. After his face showed distress, he took the initiative to ask: "What, did your train of thought wander into an alley again?"

Xu Zheng told what he had just guessed and asked again: "Mr. Yan, you said that if we follow our previous thinking, the murderer is not one person, but at least two or three people.

The motive for the crime was unknown, the crime scene was clean, and the crime techniques were very skillful.

Then this criminal gang should be familiar or slightly aware of Du Meijuan's daily life.

Even the situation of roommates like Chang Lele should be known to them, otherwise the crime could not have been committed when Du Meijuan's roommate was not around.

So I tend to think that someone in this criminal gang must know Du Meijuan.

However, the previous case handling unit investigated all the people around Du Meijuan and her boyfriend Song Hao, but no suspicious person was found.

Do you think we have missed some people, such as a friend or classmate who has a crush on Du Meijuan? "

Mr. Yan was silent. He had considered this issue repeatedly and checked the investigation records repeatedly, but he still could not solve the problem.

"Is it possible that he is Du Meijuan's colleague or neighbor?" Fang Hua added on the side.

Xu Zheng shook his head and denied that at that time, the police conducted a large number of investigations on the business staff and customers of Sanlitun bars. As for Du Meijuan's neighbors, they conducted door-to-door investigations.

Seeing Fang Hua's slightly childish round face full of hard thoughts, a flash of lightning suddenly flashed through Xu Zheng's mind, as if he suddenly solved the problem that he had been thinking about.

"Mr. Yan, I know who we missed!"

Hearing Xu Zheng's excited voice, everyone present raised their heads and looked over. Mr. Yan urged in an excited tone: "Tell me, who is he?"

Xu Zheng did not answer immediately. Instead, he opened the file on his computer and found the family downstairs in the unit where Du Meijuan lived.

"Mr. Yan, look at this investigation record. If there are no accidents, the murderer may be one of this family, or have something to do with them."

This investigation record was made by the investigators ten years ago. It is very detailed and records all the whereabouts of the four members of the family within a week of the incident.

The male protagonist was 43 years old at the time and was not in the capital at the time of the crime. This can be proven by witnesses and physical evidence.

The hostess was 42 years old and was sleeping at home at the time of the crime. Her 14-year-old daughter was also at home at the same time. The two testified against each other, plus cell phone positioning and community camera video, as well as the police’s questioning of the two of them.

It also rules out the possibility of them committing the crime.

The eldest son of this family was a 16-year-old freshman in high school and lived in school. He also had an alibi, school security and camera video, and the testimony of his teachers and classmates. This child had been in school on the day of the incident.

As neighbors of the deceased Du Meijuan, and who happened to live downstairs, this family, especially the mother and daughter, were questioned repeatedly by the police, and the transcript alone was two pages longer than the others.

It can be said that among the suspects of the police, the family's attention is only lower than that of Chang Lele. There are many reasons.

First, there is a natural conflict between going up and down the stairs.

The second is the profession of Du Meijuan and Chang Lele, bar nightclub girls, especially the former who often brings people back to do business.

The sound of bed movements and bed boards shaking in the quiet night or early morning is equivalent to the noise of a train passing by.

What's more, the family also has two children.

Therefore, the investigators at that time also focused on investigating this family, including Mr. Yan. Every time he thought of this case, he would also think about this family.

Both father and son had alibi, and although the mother and daughter had been at home on the day of the crime, no one else could prove their alibi.

However, the police investigated for a long time and even used an AI interrogation device when taking notes. Coupled with the experience and judgment of investigators, they believed that the mother and daughter had no ability to commit crimes.

All previous investigators concluded that the possibility of the family committing the crime was basically non-existent.

The same is true for Mr. Yan.

But now Xu Zheng mentioned this family again, and even acted as if he had figured out the case. He carefully recalled the investigation back then, but he couldn't figure out what they missed in the previous case.

Xu Zheng could guess what everyone was thinking by looking at everyone's expressions. He didn't hold back anymore and found the transcript of the eldest son of the family downstairs. "Everyone, take a look at these three transcripts.

These were all written by classmate Xu Chuanbin when the police reopened the case three times.

The content is basically the same, mainly saying that he stayed on campus and did not go home on the day of the incident.

As for his relationship with the deceased Du Meijuan, he admitted that he had heard the deceased's screams many times and had met several times on the stairs.

But there was no conversation.

He also acquiesced that he had released himself in the late night, in the dissolute sounds of the dead. More than once.

This situation did not ease until he lived on campus in high school. "

Mr. Yan frowned and said, "If it's just these records, it doesn't necessarily mean that this child has something to do with Du Meijuan's case."

Xu Zheng smiled and said: "In ten years, Xu Chuanbin made three transcripts, and the content of each transcript was not much different. Some sentences even came out of his mouth, and even the punctuation marks were the same.

Please take another look at Chang Lele’s transcript.

In the same ten years, a total of 11 transcripts were made for her. Although the content was the same, there were no repeated sentences with the same tone, words, and punctuation marks.

The confessions of Xu Chuanbin's parents and his sister were also recorded three times in ten years, and the repetition rate was not high. "

Fang Hua asked curiously: "Brother Xu, have you discovered this contradiction a long time ago? Why are you talking about it now?"

Xu Zheng laughed, "Of course not. Although Xu Chuanbin's transcript has a high repetition rate, it is not enough to make me doubt him. In fact, what really makes me doubt him is because of you."

Fang Hua exclaimed, "I, I have nothing to do with this case."

"Haha, your little brother Xu said that seeing you young made him think of the targets that our police had missed, because under normal circumstances, we would not focus on people like Xu Chuanbin.

Especially complex criminal cases. "

Mr. Yan now understood what Xu Zheng really wanted to say, "Xiao Xu, you are not only suspicious of the child Xu Chuanbin, right?
Is the main suspect his classmate?
Especially his classmates in the same community, middle school and high school? "

"The one who knows me is Mr. Yan." Xu Zheng was only 26 this year. At the age of 16, he already had thoughts about the opposite sex. Fortunately, Han Rui had already gone to Changming University to live on campus at that time.

Otherwise, his first love meeting would have come earlier.

"Ten years ago, Xu Chuanbin was in puberty, when his hormones began to flourish. He didn't know what it was like to be a woman, but he had already started discussing gender knowledge with his classmates.

I have even watched a lot of action art movies.

In the quiet night, he was lying on the bed alone, and the creaking and rubbing sounds from upstairs were accompanied by a high and low soprano.

How could he not have any idea at all.

In this case, most introverts keep it in their hearts, while extroverts definitely share it with their classmates and friends.

Xu Chuanbin's personality is somewhere between the two. He confessed in the police transcript that he had wild imaginations when listening to Du Meijuan's voice, and he was not shy about it.

This shows that this is not the first time he has told outsiders.

So I guess he must have told his friends what Du Meijuan did that night. "

When Xu Zheng said this, he looked at Zhu Qing, "You select Xu Chuanbin's peers from the same community, or boys who are one year apart, preferably from middle school and high school."

Only then did Fang Hua understand what Xu Zheng and his grandfather were thinking, "They are saying that although Xu Chuanbin has an alibi, he may not have committed the case.

So you doubt his little hair.

Can a person of that age handle such a complicated case? "

Xu Zheng and Mr. Yan looked at each other, and the latter laughed heartily again, "Don't underestimate people of that age, they just want to do whatever they want.

You can definitely do better than adults.

Because they will not look forward or backward, will not consider all aspects of things, and will only study one thing with peace of mind.

And his learning ability is particularly strong. "

Xu Zheng recalled what happened in his teenage years and nodded, "At that time, I dreamed of being a policeman. All I wanted to do all day was either solving crimes or committing crimes as a bad guy.

To tell you the truth, my favorite thing to think about at that time was how to commit the perfect crime.

In fact, Du Meijuan's case was not complicated. The murderer just moved the body of her boyfriend Song Hao to the crime scene, giving the impression that it was for some kind of marriage ceremony.

It is not difficult to move corpses, kill people, and deal with the scene.

The real difficulty is how to avoid the ubiquitous cameras.

I haven't figured this out yet. "

"I know." Fang Hua chuckled and reminded: "Didn't you say before that the murderer used a drone to steal the body from the funeral parlor, then they can also use a drone to transport the body."

"Drones, it might be possible in other places." Xu Zheng thought it was impossible and said speechlessly: "This is the capital, and the air is prohibited. Without approval."

As he spoke, he suddenly turned to look at Mr. Yan, "You should know the restrictions on drones in the capital ten years ago. To move corpses, large drones were needed.

It's the kind that sprays pesticides and can carry dozens of kilograms.

Even if a small drone is used to transport the matrix, the noise caused is not small.

Do you think this is possible? "

Mr. Yan did not answer the question directly, but took out a map, found the funeral home and the community where Du Meijuan was located, and drew a straight line, "Look, the straight-line distance between these two places is less than ten kilometers.

With a drone, it’s only ten minutes away.

It was just that night, although the crime occurred between 1 and 3 in the morning, no one reported the sound of a drone that day. "

Xu Zheng was a little helpless about this and had no choice but to suggest: "Then let's put this issue aside for now. I don't think there will be more discussions. It's better to investigate Xu Chuanbin and his friends first."

Mr. Yan nodded, "In fact, I personally thought that the conflict between the Xu family and Du Meijuan would not go to the point of murder, and the host and hostess were kind-hearted.

I was a little preconceived and didn't think about Xu Chuanbin's affairs.

Maybe it's because I think he's still a kid. "

He is still a child!
This sentence is usually used by the elders to excuse the younger ones. It is useless and useless.

Xu Zheng now has Dudu and feels the same way.

For example, one day when he was holding a little person while eating, he suddenly urinated and defecated on him. He would just smile softly. Not only was he not angry, but he explained to himself, "She is still a child, and she is still his own."

"Team leader, I found a person, Liu Bin, male, 26 years old, from Beijing."

At this time, Zhu Qing said in an excited voice, "His current residential address is still the community where the crime occurred, Tianlu Community in Xiyang District.

He is not only the same age as Xu Chuanbin, but also a kindergarten, junior high school and high school student.

Ten years ago, although they were in the same high school, they were not in the same class. "
