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

Xu Zheng did not answer Li Mingsheng's question, but asked to check first before talking.

Some of the methods of committing crimes are so imaginative that no matter how experienced the investigators are, they cannot say that they will be able to solve the crimes that criminals find new ways to commit.

Mr. Yan also meant the same thing, "Mingsheng, first take someone to Qiandu's headquarters and check all the documents at Yan Zi's new job, especially the software programs in his computer.

You need to find someone knowledgeable to help you identify whether he programmed the bionic robot.

Then ask their company to cooperate with you in tracing the hardware of the bionic robot. "

Qiandu Company has been researching robots for more than ten years. Although they do not mass-produce robots, they do research and testing and need to build more than hundreds of robots every year.

These robots will be dismantled as they are updated. Parts will be recycled if they can be recycled, and disposed of if they cannot be recycled.

Perhaps Yanzi’s new bionic robot accessories come from here, including biological human skin.

Li Mingsheng thought about it. Now that there is a new direction of investigation, instead of pondering Yan Zi's new crime method, it is better to investigate in this direction immediately.

Xu Zheng felt that he had done what he should do. If the truth was not true, then he had no choice, so he said goodbye, but before leaving, he asked again: "Captain Li, I don't know if you found that child His biological father?"

"The investigation found it, but the man has been abroad for two years." Li Mingsheng continued, "He and the deceased Feng Yu were college classmates and had been in love for four years.

According to the age of the children, they should have slept together four years ago when the deceased Feng Yu attended a class reunion.

We currently do not have this man’s DNA data, but his blood type was found from his previous cases, which is the same as the child’s. "

Generally speaking, since the man wearing the hat wants revenge, the first person he chooses to commit the crime should be the man who put the hat on him, followed by women and children.

Xu Zheng had seen the new information about the suspect Yanzi. He was sunny and handsome, not the kind of stiff and inarticulate coder.

Especially his first two girlfriends, even though they have been separated for many years, they still have very positive comments about him.

But good people can become bad, and they can become so bad that they destroy humanity.

Therefore, Xu Zheng suspected that if Yan Zixin really wanted to take revenge on his cheating wife, he might do other things.

He eliminated humanity and magnified the hatred in Yan Zixin's heart, "Don't Captain Li know that you are investigating the situation at Feng Yu's ex-boyfriend's parents' house?"

"This?" Li Mingsheng was surprised, "A famous college student shouldn't be so bad, right?"

After saying this, he realized that something was wrong. As the captain of the serious crime team, he was used to seeing all kinds of human tragedies in his work. Are there too many cases of patricide?

At this time, Mr. Yan was very satisfied with Xu Zheng's guess, but he sighed in his heart that he was too old to think of this.

"Young man is really thoughtful. Mingsheng, please send someone to check it out immediately."

Xu Zheng was aware of his own suffering. He could think of this, but conversely, he was not a kind person either.

Because people with a kind heart will always think better of the people and things around them, "Mr. Yan, you are a kind-hearted person, return to your original state of mind, and look at this case with kindness.

Tell the truth, the reason why you insist on investigating this case is because you sympathize with Feng Yu, mother and son?

I am different, I treat Zixin with the greatest evil empathy.

From his point of view, what kind of revenge method can avenge his shame. "

Mr. Yan laughed loudly and slapped Xu Zheng hard on the back. These words seemed to help him, an old man, to smooth things over, but in fact they were a compliment, and he even laughed at himself afterwards.

The key is that this guy not only hit the point, but most importantly, his flattery makes people feel comfortable.

"Mingsheng, learn how to flatter others. You can't just bury yourself in the case, and you can't speak too directly."

Li Mingsheng laughed and said: "That's what you always said, but Xiao Xu's words are not only right, the key is his bright mind.

Based on this alone, I can't even keep up with him. "

The three of them chatted and laughed with each other for a while, which relieved the pain and depression caused by this case, and then Xu Zheng left here on the grounds of getting off work.

Li Mingsheng arranged for people to investigate the parents of Feng Yu's ex-boyfriend, and he personally led the team to the place where the suspect Yan Zixin worked - Qiandu Head Office.

For criminal cases, Qiandu Company was very cooperative. Li Mingsheng spent half a day with a former Internet police technician and a software engineer from Qiandu Company.

Finally, among the vast sea of ​​programs in the suspect Yanzi's new workstation computer, he discovered the motion stretching program of the intelligent bionic robot written by him.

Yan Zixin did not hide or encrypt the program, or save it in matryoshka mode.

Instead, this program was directly embedded in the program code of the project he researched and developed.

There are trillions of characters in the code of a project, and it is difficult for non-professionals to discover hidden programs in it.

In addition to discovering the program he wrote, Li Mingsheng also discovered the biological human skin and robot parts newly stolen by Yanzi in the assembly subsidiary of Qiandu Company.

Without checking, you would not know that Li Mingsheng was a professional criminal investigation expert. After walking around the subsidiary responsible for assembly, he discovered that the company's management was loose.

Many employees had stolen replacement parts or acted in other unconventional ways. As for what they did after stealing these things, Li Mingsheng didn't have time to ask in detail.

He didn't even take it seriously and just took away a mechanical engineer from the company.

Before Xu Zheng got off work in the afternoon, Mr. Yan called again. It was still the case of Feng Yu jumping off a building, and there was a new case.

Originally, Xu Zheng refused to come because he also had many things to do, especially since Liu Jianghe, Zhu Qing and others had just returned from Xiangbei Province, and he was just trying to clean up the trouble for the leader.

But Mr. Yan felt that there were still some troubles in the follow-up of the case and insisted on letting him come over.

Half an hour later, in Li Mingsheng's office, Xu Zheng frowned at the information they had just investigated. As expected, something happened to Feng Yu's ex-boyfriend's father.

It happened to be the day Feng Yu jumped off the building.

The cause of the accident was simple. The deceased lived in Jin City, but his place of work was in Tanggu District, Jin City. He drove to and from get off work by himself every day.

When he got off work that day, the deceased drove a new energy vehicle and used smart driving while driving on the expressway. It was not known whether there was a problem with the smart driving or whether he made a mistake in his own operation.

At a speed of 120 yards, the car plunged into the rear of a large truck.

The Tianjin Traffic Police Accident Department is now working with relevant departments to identify the specific cause of the accident.

"Is the deceased still working at the age of 65?"

When Xu Zheng asked this, Mr. Yan became unhappy, "You brat, don't talk nonsense if you don't understand. This is a re-employment. Do you understand the re-employment?"

"Well, I'm just curious." Xu Zheng quickly admitted his mistake, forgetting that Mr. Yan was now considered a re-employee, but the old man didn't seem to want any salary.

If the case is solved, he won't get any bonus, it's just free help.

Li Mingsheng was not happy that the case was about to be solved. He opened an interrogation video and said, "This is the suspect Yanzi's new accomplice, He Guping, the bionic robot they assembled together.

He Guping thought at the time that Yan Zixin just wanted to assemble a robot to use as a toy. After all, it was not worth buying a new one.

I didn't know about Yanzi's new crime. "

"Captain Li, I see you are looking worried. Didn't you find the robot?" Xu Zheng asked his question directly without making any detours.

Li Mingsheng was worried, "We haven't found it yet. On the day of the incident, Feng Yu and her son jumped off the building. Shortly after Yanzi Xin appeared at the scene, the 120 ambulance rushed over.

Then he followed 120 to the hospital.

An hour later he took a taxi back.

The surveillance at the gate of the community could see that he entered through the gate of the community. After staying at home for less than ten minutes, he drove to the hospital.

Maybe he threw away the robot at that time. "

Most of a robot is made of metal, and Yan Zixin can't destroy it alone. Besides, even if he destroys it, He Guping can testify against him.

Xu Zheng felt that robots were not a big problem. The things that would embarrass Li Mingsheng were probably other things.

Sure enough, Li Mingsheng helped Xu Zheng pull the video of He Guping's interrogation to the end, "In order to reduce his guilt and make meritorious deeds, this guy provided us with clues about a person's crime.

You take a look first. "

In the video, He Guping racked his brains for a long time and finally said, "One time at the wine table, I heard someone brag that one of his guys killed two nightclub princesses, and the police didn't find out about it for eight years."

When the interrogators asked again, He Guping only spit out the name and appearance of the person who was bragging. Now Li Mingsheng had sent someone to locate this person.

"Drunk remarks?" Xu Zheng was extremely suspicious of people who wanted to commit crimes. In order to reduce their sentences, they would report other people's jokes to the police.

Regardless of whether it is true or false, and regardless of the feelings of friends, they are like drowning people, seizing every opportunity they can.

Telling the truth while drunk is even more difficult because it is difficult to determine whether the person is drunk and whether he is telling the truth or bragging.

Besides, who doesn't like to brag? If you take other people's bragging seriously... Well, Li Mingsheng and the others have already taken it seriously.

"Since you have already investigated this person, Brigade Li, let's continue the investigation. Maybe we can really solve a big case."

The two nightclub princesses have been missing for eight years. If they have not shown up, they are probably murdered. This case is worth investigating.

When Li Mingsheng heard that Xu Zheng also supported the investigation, he felt relieved. In fact, if he boasted like this, the investigation would probably be useless in the end.

"Mr. Yan and Xiao Xu have given their support. Then I will send someone to continue the verification. You two will leave for a while tonight and continue to provide us with technical guidance, okay?"

Mr. Yan nodded, this is work, and he also wants to see how the case will proceed.

With everyone talking about this, Xu Zheng couldn't say goodbye, so he quickly said humbly: "Mr. Yan can give you guidance, I'm here to learn."

Who would have thought that Mr. Yan followed his words and said to Li Mingsheng: "Aren't you short of manpower?

That's just right. To investigate the case of the Nightclub Princess, you send someone, and Xiao Xu and I will accompany him to investigate. What do you think? "

Li Mingsheng is in charge of the serious crime brigade. In a huge capital with a population of more than 20 million, serious crimes cannot happen every day, but some cases have a relatively bad social impact, such as the case of Feng Yu and her son jumping off a building.

It's all up to them.

Now there are other circumstances in the case, and the number of people their team can deploy is stretched thin. Since Xu Zheng happened to be here, Li Mingsheng chose to let him lead the team without hesitation.

"The relationship is good, Xiao Xu, I'll trouble you. We'll be here later. Well, I'll let Fan Yu represent the serious crime team. You and Yan Lao also know her. Is that okay?"

Xu Zheng was told by the two to make arrangements. Naturally, he could no longer object. Instead, he proposed to have Fan Yu come over as soon as possible and start investigating the case as soon as possible.

Fan Yu is a member of the Serious Case Team Six. She is about the same age as Xu Zheng and has two years of experience as a criminal police officer. The last time Mr. Yan investigated the case where a child was treated like a dog and killed, she followed the whole process on behalf of the Serious Crime Team.

Soon, a police car drove out of the city bureau and headed towards the location of the person He Guping reported.

On the way, Fan Yu contacted the police station in the area where the man was located on behalf of the Sixth Serious Case Group and asked them to send someone to look for him.

Because the location of this person was previously found through the name provided by He Guping, it was not difficult to find him.

In a street shop in Milin Town, Miyun, the capital, this man was having a drink with his friends. Fan Yu led the police from the local police station and walked towards him.

When the police in police uniform came forward, the man naturally did not dare to resist and got into the police car in confusion.

He was then taken to Milin Town Police Station, where Fan Yu and Xu Zheng immediately questioned him.

The interrogation went smoothly. When the man heard that the police were asking about the nightclub princess, annoyance flashed across his face, but he did not dare to hide it for his friend. He spit out a name without hesitation, Xu Wei.

Xu Wei is also from Milin Town. He is 45 years old this year. He has a wife and two children. He has driven online ride-hailing and taxis before. These people's self-driving taxis have seized most of the market, so he changed his profession and became a tour guide.

An old Beijing native with a sharp tongue, he was born to be a tour guide, so now Xu Wei is living a happy life.

People in the capital love to brag, and people all over the country know it.

Ten years ago, or even longer ago, taxi or online ride-hailing drivers worked in front of bars, and nine out of ten had done the job of "picking up corpses."

Even if you haven't done it before, you still have to say you do it often when bragging to others.

Therefore, the person who reported He Guping thought that his friend Xu Wei might have drunk too much and was bragging.

And he himself was also concerned with saving face, and would brag about Xu Wei's affairs after eating too much.

Coming out of the inquiry room, Fan Yu felt that what the person inside just said made sense. She was from the old capital. "Mr. Yan, Team Leader Xu, is it possible that Xu Wei was bragging at the time?"

Now that the investigation has reached this level, even if Xu Wei is bragging, he still has to investigate further, "The person just said that Xu Wei had a girlfriend eight years ago.

Called Yingying, Luo Yingying.

Check to see if Xu Wei's current wife is this woman.

If not, check the whereabouts of Luo Yingying. "

Xu Zheng felt that this kind of case was not difficult to investigate. The key was to look at the investigators themselves. Fan Yu, a big girl from Beijing, was used to thinking that Xu Wei was bragging.

If she had ended the investigation as she felt, she might have missed the truth.

Mr. Yan has been following behind, like a master protecting the calf. He was a little disappointed when he saw that Fan Yu gave a self-righteous opinion after just asking.

As a criminal police officer, you should correct your attitude as long as the suspect provides clues for meritorious service and reduced sentence.

After a while, Fan Yu walked quickly to Xu Zheng and Xu Zheng with a blushing face, and handed over a piece of paper, "Team Leader Xu, you are right, I...I was the one who preconceived the idea.

Luo Yingying should have disappeared eight years ago. "

Xu Zheng took the paper, which contained basic information about Luo Yingying. She was from Chifeng City, Prairie Province, and was 42 years old.

However, there was no case of Luo Yingying in Beijing's missing persons report record eight years ago.

There is no missing persons identification information on her.

Fan Yu investigated the use of bank cards, mobile phone numbers, WeChat, etc. under the name of Luo Yingying's ID card and found that there were none.

She is not a prison inmate, and no family member has canceled her ID card.

It is impossible for normal adults not to use their ID cards, bank cards, and WeChat once in eight years.

Even rural old men now need an ID card to apply for rural medical insurance.

Therefore, according to the information currently investigated, Luo Yingying disappeared eight years ago, and the most likely reason was that she was murdered.

The biggest suspect in her murder can only be Xu Wei.

Unless he can prove his innocence.

"Team Leader Xu, I have something puzzling. Luo Yingying has been missing for eight years. Why do you think her family didn't call the police?" Fan Yu asked curiously.

Xu Zheng was also curious about this issue, but he had handled such cases before, and it was common for family members not to call the police. "Luo Yingying was 34 years old eight years ago, working in the capital, and not yet married.

Generally speaking, she is considered an older leftover girl at her age.

If you don't get married at such an old age, your relationship with your family may not be very good.

The household registration information you just checked, the standard information for her parents is the death population.

She is not married, and she is the only one on the household register. Check to see if she has any brothers or sisters. If so, ask the local police station to ask them why they did not call the police. "

Fan Yu quickly went to the household registration department of the police station and found out through Luo Yingying's related information that she had a younger brother who was 40 years old this year.

At present, her family's location is still in Chifeng City, so she contacted the police station there according to Xu Zheng's request and asked them to conduct an investigation overnight.

Xu Zheng looked at the time. It was now 7:30 in the evening. "Mr. Yan, let's go and meet this Xu Wei. I'll rely on your sharp eyes to see if there is anything wrong with him."

Mr. Yan was worried that Xu Zheng would underestimate the enemy, so he warned, "You want to go straight to Huanglong. Aren't you afraid that Xu Wei is a criminal genius and can handle the corpse and the first crime scene so that you can't find any clues?"

Xu Zheng looked relaxed, "Believe it or not, I can guess Xu Wei's criminal motive now.

You see, eight years ago Luo Yingying was 34 years old and Xu Wei still didn’t marry her.

Why?

Not that Xu Wei was from the capital, even if he had a rural registered permanent residence, he didn't want a woman from out of town.

Luo Yingying had been with him for so many years and naturally didn't want to break up, so the two had conflicts.

Maybe Xu Wei accidentally killed Luo Yingying, maybe he did it on purpose.

Based on your experience, which one is he? "

Yan Lao blew his beard and glared, "You are becoming more and more disrespectful of the elderly, and you even question the old man.

Then I will tell you my opinion. Xu Wei should have taken the initiative to murder Luo Yingying eight years ago.

If he takes the initiative to kill someone, his heart will be full of violence and addiction, so he will kill the two nightclub princesses one after another.

Because only by killing people continuously can he get pleasure.

Whether he has continued to kill people in the past eight years or not is up to you to investigate. "

Xu Zheng flattered him, "You have always considered everything comprehensively. Then tell me, what will he do with the bodies of Luo Yingying and the two nightclub princesses?"

Mr. Yan was too lazy to answer, "Ask me everything, so why did I ask you to come?"

But now he is old and soft-hearted, and pointed to the Miyun Reservoir ten kilometers north of Milin Town...
