Chapter 537 Trap
"Mobilize the nearby police stations and traffic police teams and encircle this area first." Xu Tian asked for a map and drew a circle with a red pen, enclosing the entire area around Lucun Park.
The detachment leader took a look, took two photos and began to arrange the bayonet.
The calls were made one after another, and the city's criminal police immediately took action.
The road network and water network near Lu Village are densely covered, and there are several urban villages in front of it. However, if you go a little further, the roads leading to the inside and outside of the city are limited, and most of them have portrait bayonet. Therefore, Xu Tian It seems like a big circle has been drawn, but in fact, the requirements for police force are not that exaggerated.
Of course, the three kidnappers could also abandon the car and walk. However, not to mention whether they are aware of this problem, even if they do, it is very inefficient to take small roads instead of big roads.
When the police find their previous hiding place, or someone encounters them on the way and calls the police, the three of them are not far from the prison.
The only thing to consider is the nearby water system. There are many rivers or waterways around Lvcun Park. There is water all year round. Moreover, there are not only surface rivers, but also underground pipe networks. There is also underground water. It doesn’t matter whether there are underground rivers. clear.
The problem of water network is more complicated than that of road network, but the detachment leader's handling method is similar to that of road network.
In short, it is relatively difficult to catch people directly near Lucun Park. It is relatively easy for the three suspects to escape, but it is not so easy to escape from this area and fly far away.
If their hiding place and the time of their departure had not been known before, the three robbers would have had a good chance of escaping from Luojin City and even Baijiang Province if they secretly left near Lucun Park.
As far as the current criminal investigation mechanism is concerned, if you leave the provincial border, the probability of successful escape is still very high. But you have to have money.
Just like the former Ma Chui Chui, he was able to run all the way to Hainan while being hunted by so many people. If he had money, a stable mind, and a more resolute personality, the probability of escaping from the country or hiding would be quite high.
But, having said that, if he had a stable nature and a strong character, his roommate's children would all go to college.
In any case, the police now have the upper hand.
The three kidnappers should not know that they have been exposed now, and this is the easiest time to catch them.
Naturally, the detachment leader also wanted to get this level, and he also gave some more warnings.
Looking back, Pang Jidong, the captain of the Fourth Brigade, said: "The policemen at the bayonet are all suitable for wearing uniforms and using police cars. Even the search policemen, once spread over a large area, it is easy to alert the snake."
"It won't work without uniforms. It's inconvenient when checking people." The detachment leader paused and said: "Let's pretend to be a routine inspection for now. We can't pretend anymore. Now it's fast to fight slow..."
He spoke quickly, but his speaking speed slowed down unconsciously.
As he said, once the search starts, it is easy to alert the enemy, and the search cannot be carried out comprehensively without so many manpower.
Therefore, if the search direction is wrong, the initiative of both parties will be reversed again. The more outrageous the mistake, the more time the other party will have to escape.
"If I were a robber, I would never have imagined that the hostage well that I carefully prepared would be found in this way." During the last case, Li Haochen was silent throughout the whole process, except for his skillful movements of serving tea and pouring water. There is almost no sense of presence.
But this case is obviously within Li Haochen's range.
Li Haochen took the initiative to stand up and said: "I think we can continue as usual, and then lie in wait in the park, wait for the kidnappers to call again, and strongly demand them to prove the status of the hostages. As long as they are resolute and promise to give money, if I am the kidnapper , I should also agree. Because we are three people, we always tend to compromise in the end."
Cui Xiaohu coughed twice, knowing that this man had committed the problem of over-substitution again, so he interrupted: "It's the three criminals."
"Well... if there are three criminals, they will also be inclined to compromise." Li Haochen paused, and then said: "The hostages are still here, and the criminals have not contacted their families, so they cannot just run away. There must be another use. That’s why I feel at ease.”
It can be heard that this person has really studied criminal psychology, maybe he has experienced it in real life.
Several people present looked at Li Haochen a little strangely.
Li Haochen was not surprised. After saying what needed to be said, he fell silent again.
Xu Tian was the biggest person at the scene. He hissed and said, "If you make a trap... that's also a way..."
He looked at the detachment leader.
"Then we have to take the people back now, and bet they haven't received the news yet, and there are no eyes and ears here." The detachment leader muttered. He doesn't object, but when it comes to setting traps, if you do a good job, you should be praised. If the prisoner plays the opposite, it will easily become a laughing stock.
Xu Tian was not sure either, so he asked Pang Jidong, the captain of the Fourth Brigade on the front line.
Pang Jidong hesitated, but agreed to set a trap. If there was to be a search, he would really have to go to the front line to command. And with the urban village in front of him and the common situation of group renting in the community, the workload of the investigation would be very large and there would be a high probability that the criminal would be frightened away.
…
Jiang Yuan listened to their conversation and silently took a few steps back.
He lowered his head and slowly circled around the dry well.
There are overgrown weeds around the dry well. Although there are traces of trampling, there is very little evidence available. It has to be said that nature is the biggest enemy of detectives. There are all kinds of natural decomposers that can eliminate a lot of traces and evidence.
Blood stains, for example, may remain in a house for ten or twenty years, but in nature, if blood remains for a week, it is due to the lack of effort of microorganisms.
But on the other hand, there are also many interactions between nature and humans, far exceeding those in artificial environments.
This is helpful in solving the case at the beginning, such as...
The soft land is not only conducive to leaving footprints, but also provides a lot of information.
Given the environment of the park, it is quite difficult to avoid leaving footprints, especially when walking deep into the grass, leaving traces in the ravines.
Jiang Yuan quickly found the footprints of a pair of Nike shoes.
That big check mark was somewhat provocative to the Xingke people.
"These must be the footprints of Guo Haiyun." Jiang Yuan leaned over and measured it with his hands, called Mu Zhiyang over, took out a PAD from his backpack, and found the criminal's information to compare.
Guo Haiyun is the eldest of the trio of kidnappers. He is 48 years old this year, which is almost the age when a middle-aged man can turn his back on violent crimes. If he can endure it for another two years, most of them will become a sage in life. time.
Now...Jiang Yuan is ready to send him to the final stage of his life.
"Guo Haiyun is right." Jiang Yuan actually remembered the footprints of the three criminals and other information in his mind. However, he had to do more cases throughout the year, so in order to avoid making mistakes, he checked again and again.
All the personal information of the three kidnappers had been exposed. Jiang Yuan confirmed that it was correct and said to Mu Zhiyang, "Do you have a gun?"
"Bring it with me." When Mu Zhiyang heard what Jiang Yuan said, he immediately focused his attention, took out the gun, and checked on the spot.
"Call a few more people over and let's go around a little longer." Jiang Yuan said while calling Huang Qiangmin and said, "I want to follow a section of the trail. Can we find a dog to follow too?"
"Bureau Xu has already called people to dispatch the dogs. However, the park here is surrounded by water. Once we go out, the flow of people is complicated, and the dogs may not be able to keep up." Huang Qiangmin paused, and then said: "They are now discussing the ambush. As for the details, I’m still not sure whether it will be a dog in the end.”
"OK."
"Well, it's better to change your clothes. If you want to set a trap, it's better not to have police nearby." Although Huang Qiangmin believed in Jiang Yuan more, he tried not to destroy the unity.
Jiang Yuan agreed. It doesn't matter if he wears a police uniform or not.
"I'll ask Director Xu to send a few more people to you. Wait a minute, and I'll ask someone to find a way to get some clothes for you..." Huang Qiangmin said a few more words.
Jiang Yuan responded one by one, put away his phone, and continued to move forward, searching all directions.
After a while, Mu Zhiyang brought six people, all of whom had changed into casual clothes and brought clothes to Jiang Yuan.
Jiang Yuan changed on the spot, said hello to a few people, didn't say much, just put his hands behind his back and continued walking with his head down.
The detectives present were currently discussing wildly that Jiang Yuan had used pollen to catch the hostage. Looking at Jiang Yuan, they all looked like they were looking at a magician. They were all very well-behaved.
Mu Zhiyang divided them into three pairs and followed him and Jiang Yuan in a Zigzag formation, protecting them secretly.
Jiang Yuan didn't even need to worry about these, he just lowered his head and looked for the footprints.
The soil in the park is soft and unstable. The criminal may or may not leave footprints on the soft ground. But on hard ground, there will be almost no traces left. The park is cleaned regularly, and the water from watering the plants in the afternoon may wash away the traces.
However, overall, it is still easy to follow Guo Haiyun's footsteps.
He probably had no awareness of counter-reconnaissance, at least not seriously in this park.
Perhaps in the mind of the kidnappers, the dry well in the park they temporarily chose should not be found by the police at all, unless they confessed themselves.
As for footprint tracking, criminals with little education don't know much about it.
Jiang Yuan clasped his hands behind his back, looking and walking slowly like an old man.
The footprints are all directional, and it is easier to see clearly when you are on pointe. Guo Haiyun is used to using his big toe to make turns, so it is easy to see.
After a while, Jiang Yuan walked further and further.
Mu Zhiyang and others followed Jiang Yuan, feeling a little bored and nervous.
Looking from a distance, several people have turned into small dots.
Woo...
A car roared past the door. Jiang Yuan looked up again, only to find that the park exit was in front of him.
This is a side entrance to the southeast.
There is a messy road outside.
The side door is a manual revolving door that only allows walking. Only one person can pass through at a time. However, there is a public toilet on the side of the park inside the door. Many people from outside the park come in and out just to use the public toilet.
"This park is quite unfriendly to dogs." Jiang Yuan said this and frowned slightly.
This kind of scene with toilets, broken roads, chaotic pedestrians outside, and street stalls in villages in the city is a great challenge to police dogs, as well as to people.
