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

In Leishan Town, the bungalow with a small courtyard where Guo Mingzhu lived ten years ago is located on the outskirts of the town. However, with the development nearby, the former bungalow has also been built into a three-story villa with a courtyard.

Xu Zheng and the others came here to dig three feet into the ground.

According to the municipal sewage discharge department, the sewers in this area have not been cleaned in the past ten years.

Therefore, in order to find Guo Mingzhu, he killed children.

Xu Zheng and the others decided to dig a sewer here because of the little debris left after the bones were separated.

Although there is little hope, what if we find some clues?

This is also because they have searched Guo Mingzhu's home in Jin City and found no clues related to the case.

In the end, everyone had to gather in Leishan Town, and a wave of people visited all residents of Leishan Town who were registered ten years ago.

The other wave was when the people who directed the on-site survey and trace inspection, with the support of the Leishan Town Police Station, conducted a comprehensive excavation of the sewers in the yard where Guo Mingzhu lived ten years ago.

The bungalow here has been transformed into a three-story building, but the sewer outside their yard has not been renovated.

It is still the sewer system built by the municipal engineering project more than ten years ago.

Unfortunately, the sewer in the yard was renovated when the house was renovated.

The rubbish they pulled out of the sewers back then had long been thrown into the trash can.

Now Xu Zheng and the others can only hope that they can find what they need by digging through the sewers in this area.

This is a big project. All the sewers with a total length of 400 meters need to be cleaned. No other garbage is needed, only bones.

When Xu Zheng and Mr. Yan arrived here, the work was already in full swing. The hired workers got into the sewer, pumped out the water in this section of the sewer, and began to pump out the sludge.

Then the sludge is rinsed clean, and every bit of bone residue inside has to be screened out.

Of course, the majority of the silt is pebbles. After all, the sewers are under the road. When it rains, the rain carries the pebbles and settles down below.

Because too much silt was excavated and the air was hot during the day, the trace inspection staff worked directly on site and worked hard under the activity tent, enduring the stench.

This was not the first time Xu Zheng had seen such large-scale on-site operations searching for clues, but this time, he felt a bit suspenseful.

Because there is no evidence to show that Guo Mingzhu was the child treated in this small courtyard.

But because there is no evidence, even if there is only a one percent possibility, all investigators are willing to search the sewers.

Mr. Yan stared at the black mud and ignored the fishy smell in the air, "Xiao Xu, you can't put your hope in the existing investigation.

You still need to come up with a better way, otherwise, this case is likely to become an accidental case. "

Xu Zheng saw that Mr. Yan regarded him as the leader of the investigation of this case. He smiled bitterly in his heart. The case had reached this level unless evidence or witnesses were found.

Of course, the best outcome is to find Liang Huan, the human trafficker.

"Mr. Yan, you said that someone like Guo Mingzhu accidentally killed his first child. Can he accidentally kill his second child again?"

Mr. Yan turned his head, a look of hesitation flashed on his face, "You mean, the second child was not killed by Guo Mingzhu, but by someone else. Well, what you said makes sense.

The first time he didn't see clearly what was in the bag, and he dropped it directly according to his habit, so the second time

No, according to the information, he stopped selling dog meat at a stall shortly after the incident.

If the second child was not killed by Guo Mingzhu, there are two possibilities.

One is that Liang Huan killed the child, took it to Guo Mingzhu's house, and forced him to ask for money.

The other is that Liang Huan found another dog meat seller and defrauded him again. "

Xu Zheng opened the electronic map on his mobile phone and found Leishan Town, "I remember that ten years ago, the only people selling dog meat here were Guo Mingzhu and his family, if it is the second possibility you mentioned.

Liang Huan should go to other places to sell stray dogs.

You see, to the west of Leishan Town is the Sixth Ring Road, and to the east is Tianjin City. Going north to south should be his best choice. "

"According to what you said, we need to find the dog meat restaurant or dog meat vendor from ten years ago." Mr. Yan pondered for a moment, "Eggs cannot be placed in a frame, since we need to check.

I see that in several nearby towns, as well as inside and outside the Sixth Ring Road, all suspicious dog meat restaurants or dog meat vendors ten years ago had to be investigated. "

Xu Zheng nodded in agreement, but before he could continue speaking, Li Mingsheng suddenly walked over quickly with joy in his eyes, "Mr. Yan, Xiao Xu, good news.

Ten years ago, around the time of the incident, a resident of Leishan Town saw Guo Mingzhu riding his stall truck east toward the North Canal in the middle of the night on a rainy night. "

Xu Zheng asked hurriedly: "Is that person sure that the day he saw Guo Mingzhu was July 7.12th?"

"I'm just not sure." Li Mingsheng felt a little regretful, "This person is Guo Mingzhu's customer and often buys dog meat from his stall.

Seeing him going out in the rain in the middle of the night, he asked.

Guo Mingzhu just replied that he had something to do and needed to go back to his hometown. "

Mr. Yan then asked: "In the video recordings of various cameras in Leishan Town that we sealed ten years ago, can Guo Mingzhu be found on July 7.12?"

"No, it's still because of the heavy rain." Li Mingsheng pointed to the east, "Do you think it's possible that Guo Mingzhu threw the child's body into the Bei Canal in the dark night and heavy rain?"

"Of course this is possible." Xu Zheng also thought so.

After all, it is much better to throw the bones into the river than throw them into the trash can, or decompose them and throw them into the sewer.

Mr. Yan looked to the east, "The North Canal is located five miles east of Leishan Town. Guo Mingzhu rode his electric tricycle. Even if it rained heavily, it took at most half an hour to go back and forth.

I think we can send someone into the water to fish it out. "

Li Mingsheng made further progress and affirmed: "We asked many people, and we also asked people from the Leishan Town Police Station.

They have never received any reports that Guo Mingzhu killed stray dogs.

But in Leishan Town ten years ago, some people said that there were indeed a lot fewer stray dogs.

I suspect that even if Guo Mingzhu did not kidnap stray dogs himself, he must have bought them.

So what does he do with stray dog ​​fur?

It's definitely not possible to throw it in the trash can. The dog's fur is very heavy and has a strong fishy smell, so I think he will throw the fur into the North Canal. "

The North Canal is very wide, and transportation on both sides is convenient. Find a place where no one is around, tie up stones and throw them inside.

Xu Zheng reminded: "Team Li, the North Canal is very long. We don't know where Guo Mingzhu will throw it, so you have to ask the colleagues involved in the salvage to be more patient."

Li Ming laughed loudly, "Don't worry, as long as there are clues, I can turn the North Canal upside down."

Soon, Xu Zheng saw the swiftness of the Beijing City Police. Li Mingsheng walked aside and made a few calls. After ten minutes, seven or eight salvage boats floated over from the North Canal.

Obviously, they are a private company hired by the police to perform salvage operations. Compared with them, even if the Changming police had money to hire a private salvage boat, they were not so generous as to bring in seven or eight boats at once.

Li Mingsheng started salvaging, and Xu Zheng and Mr. Yan took their people back to the city bureau first.

They are not on vacation when they come back. Except for Mr. Yan, everyone has a job. Someone has to investigate how many dog ​​meat restaurants or mobile vendors there were near Leishan Town ten years ago.

Someone needs to sort out Liang Huan's actions ten years ago

After multiple investigations, three dog meat restaurants were soon discovered.

Judging from the industrial and commercial registration, these three dog meat restaurants were found, but only one is still in business, and the other two have long since been canceled.

Moreover, the business license of this one that is still closed has been canceled and replaced.

However, because they had registered their names and phone numbers with the Industrial and Commercial Bureau ten years ago, their specific information was quickly found, and their location was also found through mobile phone positioning.

By the time the three people's information was delivered to Xu Zheng's desk, it was less than twenty minutes before they returned.

"Mr. Yan, the work efficiency of the Municipal Bureau is very high."

"What does this mean? Nowadays they are all electronic files. As long as there is a name, these information are not difficult to check."

The two chatted while checking the information of the three dog meat restaurant owners.

Ten years ago, the dog meat restaurants they opened were not too far from Leishan Town. They were all outside the Fifth Ring Road. Except for one in Xiaoxing District, the other two were in Tongzhou District.

So the question is, which of these three companies is suspect?

It's impossible, all three families must be suspected.

"Mr. Yan, I think we should stop thinking about it. The owners of the three dog meat restaurants are all in the capital now. How about you work hard and come with me?" Xu Zheng suggested.

In fact, this job does not require you to come to the door in person. You only need to notify the police station in the jurisdiction where these three people are now and ask them to come over.

Moreover, Xu Zheng is only a consultant on this case. If he comes to visit, he must be accompanied by someone who is officially handling the case.

Yan always understood why Xu Zheng had to go there in person, because only by going there in person could he see the three people's reactions at first glance and guess which of them was the suspect.

"You call Fan Yu from Group 6 and ask her to come over, and we can visit her in person." Mr. Yan told Zhu Qing.

When Fan Yu came over, Xu Zheng and his party drove to the nearest dog meat restaurant owner's house.

Sheng Zhongxin, 52 years old, lives outside the Fifth Ring Road in Beijing, near Shibali Bridge, and now runs a small supermarket.

When Xu Zheng and others came to the door, he was guarding the store, playing with his mobile phone in his hand, without raising his head. He didn't raise his head until Xu Zheng stood in front of him, "Are you going to buy something? "

Xu Zheng waved his hand and asked Fan Yu to show her police officer ID before he took out his mobile phone and said, "Mr. Sheng, we have a case that requires your cooperation.

If it's convenient for you now, please look at my phone. Do you know this person? "

Sheng Zhongxin was so fed up that he was stuck at the checkout counter and asked if it was convenient, but he didn't dare not cooperate because the policewoman took out a criminal police work permit.

Who would want to provoke the criminal police, so he could only cooperate, took Xu Zheng's phone, looked at it carefully, and said "eh".

"This is not what that is called."

"Liang Huan?"

Sheng Zhongxin nodded quickly, "Yes, that's the name. It has the same name as an old star in our old capital. So you are looking for him."

Xu Zheng felt happy that Liang Huan was indeed a professional person who bought stray dogs secretly, but at the same time he felt worried because when Sheng Zhongxin talked about Liang Huan, he did not look panicked.

Before he could ask again, Sheng Zhongxin spoke quickly and took the initiative: "You are looking for the wrong person when you are looking for me. He and I did have an intersection, but that was ten years ago.

To tell you the truth, I ran a dog meat shop more than ten years ago.

This guy didn't follow the right path and stole stray dogs and sold them to me.

Hey. As you know, although it is more troublesome to peel and remove the skin of this stray dog, it is cheap.

So, I bought from him a few times.

But not many. When I think about it, there don't seem to be ten.

Later this guy quit and I cut off contact with him."

Xu Zheng listened to Boss Sheng's long speech, describing in great detail how he and Liang Huan met and how they discussed business. He looked like a chatty old Beijinger, and he couldn't stand it.

"Boss Sheng, please leave us your contact information. We have other tasks today. If necessary, we may contact you again."

After coming out of here, Xu Zheng breathed a sigh of relief and hurried to the next house.

Fan Yu saw that Xu Zheng was not adaptable to the enthusiasm of the people in the capital, so he wanted to take the initiative to take over the next job, "Team leader Xu, how about I come to ask questions later and you can support me from the side?"

"That's okay." Xu Zheng followed suit and reminded: "We will come here one by one this time. The most important task is to observe their first reaction."

As long as the dog meat restaurant owner sees the photo of Liang Huan and his two children, his first reaction will be different, such as panic, fear and other negative emotions.

Or the contraction of pupils, disordered breathing, etc. may be related to the case.

The second dog meat restaurant owner I found is very young. He is only 36 years old this year. He was only 26 years old ten years ago. At such a young age, he is running a dog meat hot pot restaurant with an area of ​​more than square meters.

However, now they are no longer a dog meat hot pot restaurant, but a Sichuan and Chongqing hot pot city.

It was already past three o'clock in the afternoon when Xu Zheng and the others arrived at Sichuan-Chongqing Hot Pot City.

At this time, the hot pot city was taking a break, and the boss Hua Xu received Xu Zheng and his party in his office on the second floor.

Entering the office, Fan Yu showed his ID without saying anything. Hua Xu was stunned and said, "Interpol? Police officers, what can I do for you?"

"Mr. Hua, we have a case here that requires your cooperation. It's like this. Do you know this person?" Fan Yu took out his mobile phone and found Liang Huan's photo.

"No, I don't know." Hua Xu didn't know why. He looked at this group of policemen, or criminal policemen, staring at him eagerly. He was a little nervous. He glanced at his phone and said he didn't know him, and wanted to send them away early.

Just at this glance, his nervous heart suddenly jumped.

He really knew her because of the photos on his phone.

Even very familiar.

When people are panicked, they often forget to manage their expressions.

Xu Zheng and Mr. Yan saw clearly that after the hotpot city owner saw the photo, panic flashed in his eyes and his lips trembled instantly. Just as he was about to explain, he clenched his teeth subconsciously.
