After finding Zhongye, Jiang Yuan finished watching the scene he suspected, but it was still a long way to sweep the entire section of the road.

At this time, everyone in the four cars was already in short supply.

Mu Zhiyang and others were in charge of the escort. The criminal technician who followed the survey vehicle had to run around with various lamps and instruments in their arms, and they were tired.

Cui Qishan, Xiao Si and others were thinking about it. Liu Jinghui started to use his brain, and the popularity of the brain flower was also on the line.

"Okay. Let's take a rest." Jiang Yuan waved his hand and announced his dissolution.

"It's okay. After resting, think about it carefully." Liu Jinghui breathed a sigh of relief. He was in his forties and should have been in the private enterprise for 10 years. He could no longer bear it after staying up late like this.

Everyone shouted long live and began to pack up their things.

Xiao Si came out and said, "Don't you wait for the dog?"

The group of detectives who were packing up their things were all stiff.

Cui Qishan pulled Xiao Si in a pity and said, "You can't save some time? Director Jiang's orders have been issued. What suggestions are you here? So many people will make you notice?"

He was also afraid that Xiao Si would arouse public anger.

But Xiao Si was not afraid. He was used to being a minority and said unmoved: "It has been so many days on the scene. The window for using dogs is getting shorter and shorter. It will be dawn in two hours. At that time, the police dogs should be allowed to come. When the morning rush hour comes, there will be a car on the road here. Once the exhaust is fuming, it will be useless for any dogs."

It is okay for a normal police dog to smell the smell within a few days. If it is indoors, it will also smell the smell a few weeks ago.

The conditions in mountainous areas cannot be compared with indoors. It is more metaphysical whether you can smell the information of the victim. It is not only related to dogs, but also to the temperature and humidity these days. The time is definitely less than indoors. The specific amount is not necessarily the case.

In short, since you have decided to use the police dog, the faster the better.

The criminal police present understood what Xiao Si said. Therefore, although they were so sleepy that they were dying, the few of them still accepted their fate and slowed down.

Such inhuman things as working for 24 hours in a row are daily in the criminal police team.

"Okay, everyone else can rest first, I'll wait." Jiang Yuan waved his hand and said, "Mu Zhiyang and Wen Ming stay with me, let's deal with each other for a night."

"Oh." Mu Zhiyang and Wen Ming both wore bulletproof vests when they followed Jiang Yuan, and they didn't dare to put Jiang Yuan in the wilderness.

"I'll be with you too." Xiao Si also knew the reason why the minority was going to be beaten.

Cui Qishan was swearing in his heart, but he was still a middle-aged man: "This is the case of our Fourth Brigade, so I'll accompany you too."

"It's not necessary for you to accompany you, so we will go directly to stay in the hotel in Jinshan." Jiang Yuan's answer was unexpected.

Cui Qishan: "It's only two hours..."

Xiao Si: "Five-star hotel?"

If the criminal police are on a business trip, they will stay in one room for two people, and the subsidy is not enough for the five-star hotel in Beijing. Not to mention that they are not considered business trips at all. As for staying in a hotel for two hours of rest, this is even more unreasonable. The normal operation is to deal with the whole night in the car. It is common to keep a dozen hours of follow-ups, so what can’t be handled with two hours?

But looking at Jiang Yuan opposite, Cui Qishan and Xiao Si were speechless again.

"Then...we'll go back?" Cui Qishan felt that it was useless to stay and it was not appropriate to leave, so he glared at Xiao Si fiercely.

"Yeah." Jiang Yuan noticed Cui Qishan's eyes and said, "Shen Yaowei, please contact the police dog brigade here. Call me when the person comes."

"Yes!" Shin Yaowei stood attentively and saluted.

Cui Qishan began to feel embarrassed again and hurriedly said, "Or I'll wait, I'll be more familiar with the police dog brigade."

"Bao Cui, you go and have a rest first. It will be convenient for me to contact the members of the case-based special team at that time." Shin Yaowei raised his chest and looked up, trying his best to dissuade Cui Qishan. Many of his recent limelight have been snatched away by the new Wei Shi. Finally, he got such an opportunity to stand alone and didn't feel sleepy at all.

Cui Qishan looked at Shin Yaowei's expression carefully, moved by him, and turned around and said, "Let's do this, Xiao Si, stay here and accompany Shin Yaowei. If you encounter a criminal who returns to the crime scene or something, you will also take care of each other."

"Yes." This is a direct order, and Xiao Si can only respond.

...

It was dawn and the police dog competition began. The police dog trainer raised his hand...

Five police dogs sniffed the old clothes used by the victim Yan Meixuan for a long time, and then sniffed along the road accompanied by the instructor.

Jiang Yuan, who had only slept for less than two hours, insisted on speaking to the trainers of the police dog brigade, and then put them behind the dogs.

The police dog has not been online yet, and it is not certain when it will be online, so I can only wait behind.

Jiang Yuan looked around from time to time, hoping that while there was sunshine, he could see the information he could not see last night, but he never could do it. To put it bluntly, it was not online either.

Two hours later, the five police dogs set out again and returned without success. The captain of the police dog brigade could only come over helplessly and said, "We have to take a break first. At least the area we have found is not as good as a victim."

"Then let's take a break and find a roadside breakfast." Jiang Yuan knew he couldn't hurry, so he found a buffer belt he had seen before. Several people sat around and shared the pancakes bought by Cui Qishan.

The pancakes taste good, and the pancakes are still covered with crispy cakes. Even with ordinary taste, they are within an acceptable range.

Jiang Yuan was hungry all night, and ate one whole, took another one, drank the remaining half cup of soy milk, and got up and looked around. He didn't finish the meal.

There are more and more cars on the road.

Before noon, all the police dogs became listless.

The consumption of police dog sniffing is also huge, the more complicated the place is.

However, the resources of the Beijing Bureau are invincible, not to mention that the task force led by Jiang Yuan, the captain of the Police Dog Brigade himself allocated five police dogs to come over and transported the police dogs who had participated in the war back for rest.

Naturally, Jiang Yuan and others could not get a rotation. They followed the newly replaced police dog to Jinshan Park, but still did not find it.

There has been surveillance here, but the surveillance has not been discovered. There is no need to let the dog sniff it again.

"Director Jiang, our police dog brigade can only do this. I'm really embarrassed to be unable to help." The police dog brigade let out a sigh of relief, not as if he was relieved, but he also quietly breathed a sigh of relief.

"It's okay." Jiang Yuan waved his hand.

"Then let's go back first." The captain felt relaxed and felt that Ning Tai and Jiang Yuan were quite easy to talk to.

Jiang Yuan shook his head and said, "Don't be so anxious."

"Um?"

"Let's help us eliminate another option." Jiang Yuan looked at Liu Jinghui later.

When Liu Jinghui heard Jiang Yuan's tone, he knew what he was thinking, so he asked: "What kind of scope do you want to find?"

"Suppose the criminal lives or works from the subway station to Jinshan Park, and sniffs it for a few kilometers around." Jiang Yuandao.

The captain of the police dog brigade next to him turned green and said hurriedly: "There are a few kilometers around, and the range is too large. If you can't smell it, there is no one like that."

"Isn't you asking you to find a trace?" Jiang Yuan paused and said, "Look for the corpse."

The professional corpse hunting dog has a large working range. The open terrain with sufficient training can sweep more than one square kilometer per hour on average. The complex terrain may be reduced by half, but the efficiency is still very high and the accuracy is also very good.

The captain of the police dog brigade was a little surprised: "Are you starting to find the body?"

"If you can't find the best, you will rule out this option." Jiang Yuan didn't say much. There was a reason why he talked about the surrounding few kilometers.

During the investigation last night, Jiang Yuan had already discussed with Liu Jinghui the possibility of the criminal being a local resident. Among all forms of crime, many murderers like to commit crimes locally, which often gives them a sense of security and familiarity with the local area, which can also help them commit crimes smoothly.

As for the environment around Jinshan, the murderer who is willing to commit crimes locally is likely to deal with the corpse around Jinshan. This is not a principle of a criminal case, but a decision made by the characteristics of the capital.

In terms of strict management, inspections in Beijing may be more detailed than entry and exit. It may be better to leave Beijing, but if the murderer wants to come in, the vehicle and himself must pass through a checkpoint with dog duty.

The captain of the police dog brigade looked at the others on both sides, then understood and said, "Then I have to report it and send the corpse-seeking dog again."

"Yes." Jiang Yuan nodded.

An hour later, two professional police dog transport vehicles drove over.

The leader who came down to command was already the police supervisor with a silver olive branch.

"I've transferred all the corpse-seeking dogs that can go into battle immediately." After the third-level police supervisor in the team leader shook hands with Jiang Yuan and others, he arranged personnel to search.

From the walkie-talkie, the sound of subordinates reporting from time to time came.
