Chapter 510: Trap

"Mobilize the nearby police stations and traffic police teams, and surround this area first." Xu Tian asked for a map, drew a circle with a red pen, and included the entire area near Lü Village Park.

The detachment leader took a look, took two photos, and started arranging the checkpoints.

One phone call after another went out, and the criminal police in the city immediately moved.

The road network and water network near Lü Village are dense, and there are several urban villages nearby. But if you pull it further, the roads leading to the city and outside the city are limited, and most of them have portrait checkpoints. Therefore, although Xu Tian seemed to draw a large circle, in fact, the requirement for police force was not that exaggerated.

Of course, the three kidnappers can also abandon the car and walk. However, not to mention whether they can realize this problem, even if they really do this, not taking the main road but only taking small paths, the efficiency is also very low.

By the time the police find their previous hiding place, or someone meets them halfway and calls the police, the three of them will not be far from prison.

The only thing to worry about is the nearby water system. There are many rivers or waterways around Lü Village Park, which have water all year round. Moreover, not only are there surface rivers, but there are also underground pipe networks. Groundwater naturally exists, and it is unclear whether there are underground rivers.

The problem of the water network is more complicated than the road network, but the detachment leader's handling method is similar to the road network.

In short, the difficulty of catching people directly near Lü Village Park is relatively large, and it is relatively easy for the three suspects to escape. But escaping from this area and wanting to fly far away is not that easy.

If they didn't know their hiding place before, and didn't know the time they left, then the three robbers, sneaking away from near Lü Village Park, still had a not-small probability of escaping Luojin City, and even the scope of Baijiang Province.

According to the current criminal investigation mechanism, if they leave the provincial border, the probability of successful escape is still very large. But they must have money.

Like the former Ma Chuichui, under the pursuit of so many people, he could run all the way to Hainan. If he had money in his hand, and was mentally stable and firm in character, the probability of escaping abroad or hiding would be quite high.

However, having said that, if he were mentally stable and firm in character, his roommate's child should be in college.

In any case, the police now have the advantage.

The three kidnappers should not know that they are exposed now, and this period of time is the easiest time to catch them.

The detachment leader naturally thought of this layer and also gave a few more instructions.

Turning back, Pang Jidong, the captain of the Fourth Brigade, said: "It is appropriate for the police at the checkpoints to wear uniforms and use police cars. It is the police officers who search. Once they spread out on a large scale, it is easy to startle the snake."

"It won't work if you don't wear a uniform. It's inconvenient when checking people." The detachment leader paused and said: "Everyone first pretends to be a routine inspection, and then talk about it when you can't pretend anymore. Now it is to hit the slow with fast..."

He said fast, but the speed of his speech slowed down unconsciously.

Just as he said, once the search starts, it is easy to startle the snake, and the search cannot be spread out comprehensively. There is not enough manpower.

Therefore, if the direction and position of the search are wrong, the initiative of both sides will be reversed again. The more outrageous the mistake, the more time left for the other party to escape.

"If I were a robber, I probably wouldn't have thought that the hostage well I carefully prepared would be found in this way." Li Haochen was silent throughout the last case. Except for the skilled action of serving tea and pouring water, he almost couldn't find a sense of existence.

But this case was obviously within Li Haochen's range.

Li Haochen took the initiative to stand out and said: "I think we can keep everything as it is, and then ambush in the park, wait for the kidnappers to call again, strongly demand them to prove the condition of the hostages, as long as the attitude is firm and promise to give money, if I were a kidnapper, I should also agree. Because we are three people, we will always tend to compromise in the end."

Cui Xiaohu coughed twice, knowing that this guy's problem of being too substituted had committed again, and interrupted: "It's three criminals."

"En... if it's three criminals, they will also tend to compromise." Li Haochen paused and said: "The hostages are still here, and the criminals haven't contacted the family members, so it's impossible to run away just like that. They always have to use them again to feel at ease."

It can be heard that this guy has really studied criminal psychology, and maybe he has really experienced it.

The eyes of the few people present looking at Li Haochen were a bit strange.

Li Haochen was not surprised, finished what he had to say, and fell silent again.

Xu Tian was the biggest on the scene, "hissed" and said: "If you make a trap... it's also a way..."

He looked at the detachment leader.

"Then we have to bring people back now, and then bet that they haven't received the news, and there are no ears and eyes here." The detachment leader muttered. He didn't object, but setting a trap, if done well, it should be praised. If it was played by the criminal, it would easily become a laughing stock.

Xu Tian was also not very sure, and asked Pang Jidong, the captain of the Fourth Brigade on the front line.

Pang Jidong hesitated slightly, but supported setting a trap. If he wanted to search, he would really have to command on the front line, and with the urban village nearby and the common group rental state of the community, the workload of investigation would be very large, and in the end, it would likely be that the criminals were startled away.

Jiang Yuan listened to their conversation and silently took a few steps back.

He lowered his head and walked around the dry well slowly.

The dry well was overgrown with weeds. Although there were traces of stepping, there was very little evidence that could be obtained. It must be said that the natural world is the greatest enemy of detectives. Natural decomposers are of all kinds and can eliminate a lot of traces and evidence.

Like bloodstains, perhaps they can remain in the house for ten or twenty years, but in the natural world, blood remaining for a week belongs to the microorganisms not working hard.

But on the other hand, the interaction between the natural world and people is also very large, far exceeding the artificial environment.

This is conducive to solving the case at the beginning of the case, for example...

Soft soil is not only conducive to leaving footprints, but the information provided is also extra.

In the park environment, it is quite difficult to avoid leaving footprints, especially when you want to walk deep into the grass, it is inevitable to leave traces between the trenches.

Jiang Yuan quickly found a footprint of a Nike shoe.

That big check mark, for criminal science people, is more or less a bit provocative.

"This should be Guo Haiyun's footprint." Jiang Yuan bent down and measured it with his hand, called Mu Zhiyang over, took out a PAD from his backpack, and then found the criminal's information to compare.

Guo Haiyun is the oldest of the kidnapper trio, 48 years old this year, which is almost the age of the return of the light of violent crime for a middle-aged man. If he could endure for another two years, most of them would enter the sage time of life.

Nowadays... Jiang Yuan was ready to send him into the last stage of his life.

"It's Guo Haiyun, no mistake." Jiang Yuan actually remembered the footprints and other information of the three criminals in his mind, but after doing many cases throughout the year, in order to avoid mistakes, he checked again and again.

The personal information of the three kidnappers had all been exposed. Jiang Yuan confirmed it was correct and said to Mu Zhiyang: "Did you bring a gun?"

"Brought it." Mu Zhiyang heard Jiang Yuan say this, his attention immediately concentrated, and he took out his gun and checked it on the spot.

"You call a few more people over, let's go around a few more times." Jiang Yuan said while calling Huang Qiangmin: "I want to follow a footprint, should we find a dog to follow."

"Xu Ju has already called people to adjust the dog, but there is water around the park here. Once you go out, the flow of people is complicated, and the dog may not be able to follow." Huang Qiangmin paused and said: "They are discussing the details of the ambush now, it is not certain whether the dog will be used in the end."

"Okay."

"En, it's best to change clothes. If you want to set a trap, it's better not to have police nearby." Although Huang Qiangmin trusted Jiang Yuan more, he also tried his best not to destroy unity.

Jiang Yuan responded. It didn't matter whether he wore a police uniform or not.

"I'll let Xu Ju send a few more people to you, wait a moment, I'll find a way to get some clothes for you..." Huang Qiangmin gave a few more instructions.

Jiang Yuan responded one by one, put away his mobile phone, continued to move forward, and searched in all directions.

After a while, Mu Zhiyang brought six people, all of whom had changed into casual clothes, and brought clothes for Jiang Yuan.

Jiang Yuan changed on the spot, greeted a few people, didn't say much, carried his hands on his back, and continued to walk with his head down.

The criminal police present were frantically discussing Jiang Yuan's use of pollen to find the hostages, and looking at Jiang Yuan was like looking at a magician, each one was very obedient.

Mu Zhiyang divided them into three pairs, presenting a product shape behind him and Jiang Yuan, secretly protecting them.

Jiang Yuan didn't even need to care about these, just lower his head and find footprints.

The soil quality of the park is soft and uncertain. The criminal may leave footprints on the soft ground, or may not. But on the hard ground, traces are almost never left. The park is cleaned regularly, and the water from watering flowers in the afternoon may also wash away the traces.

However, in general, it is still easy to follow Guo Haiyun's footprints.

He should also have no consciousness of counter-reconnaissance, at least in this park, he didn't do it seriously.

Perhaps in the kidnapper's mind, the dry well in the park he temporarily chose should not be found by the police at all, unless they confessed it themselves.

And things like footprint tracking, criminals with little education, don't know much about it.

Jiang Yuan carried his hands on his back, like an old man, looking slowly, walking slowly.

Footprints all have directions. It is better to see clearly when there are toes. Guo Haiyun is used to using his thumb to exert force when turning, so it is easy to see.

After a while, Jiang Yuan walked further and further.

Mu Zhiyang and others followed near Jiang Yuan, a bit bored, and a bit nervous.

Looking from a distance, several people had already become a small point.

Woo...

A car whizzed past the door, Jiang Yuan looked up again, only to find that it was already the exit of the park.

This is a side door in the southeast.

Outside is a messy road.

The side door is a manual revolving door that only allows walking, and only allows one person to pass each time. But on the side of the park inside the door, there is a public toilet, so many people outside the park enter and exit just to use the public toilet.

"This park is quite unfriendly to dogs." Jiang Yuan said this, his brows slightly wrinkled.

This kind of toilet plus broken road, plus chaotic pedestrians, and the scene of street stalls in urban villages, is a huge challenge for police dogs, and why not for people. ===== CHAPTER 511 =====
