Mystery Tracker 2

Everyone wanted to find out Geng Qiang's hiding place from Hao Jie's mouth, but they didn't expect Hao Jie to be unable to contact him.For the serious crime team, this is definitely not good news.According to Hao Jie's account, the reason why Geng Qiang agreed to help her steal the child was because Hao Jie said that she would sell the child and give the money to Geng Qiang.But I didn't expect Geng Qiang to be killed. According to common sense, Geng Qiang would probably sell the child himself, and then run away as soon as possible.Therefore, they had to catch Geng Qiang before he ran away, otherwise he and the child would be hard to find.It's just that the serious crime team now has limited clues, and how to find them has become the biggest problem.While everyone was scratching their heads anxiously, Shen Hao came up with a plan.

"We can use the mobile phone to perform triangulation." Shen Hao explained, "Use the transmission time required for his mobile phone to receive three signal sources to measure the distance, and then calculate the three-dimensional space where the receiver is located based on these three distances." Coordinate values. This is how our mobile GPS navigates.”

"Then what if he doesn't turn on his mobile phone to navigate?"

"As long as he can keep the call." Shen Hao said, "As long as he can keep the call, we can lock him through the relationship between his mobile phone and the signal tower. But there is a problem with this, that is, it takes A certain amount of time, so you have to let him talk for a certain amount of time."

"Xiao Hao," Shen Yan looked at his younger brother and asked, "How accurate is this positioning?"

"If the effect is ideal, the error is within 50 meters."

Shen Yan and Cheng Jinsong exchanged glances, and finally decided: "Okay, then follow your plan!"

October 5, 9:18pm.

A phone rang, and an arm with tattoos reached into the trouser pocket, and took out the phone from it: "Hello?"

A sweet female voice came from inside: "Hello, sir, this is China Mobile XX Provincial Branch. We are currently conducting a survey with prizes. As long as you cooperate with us to answer a few questions, we will give you 100 Yuan phone bill. I wonder if you are interested, sir?"

The man glanced at the caller ID: 10086, it is indeed the customer service number of China Mobile, so he moved the phone to his ear again: "Okay, let's ask."

"Okay. Are you the owner of the machine?"

"Yes."

"Please tell me your name and the last four digits of your ID number."

"Geng Qiang, the last four digits of the ID card... 7397."

"Okay, how long has Mr. Geng been using this number?"

"Two or so months."

"Okay, did you use our mobile phone number before?..."

In the office of the Municipal Bureau, Shen Hao was sitting in front of the computer, staring at the changes on the screen with all his attention. He saw the cursor on the screen constantly flickering, and a circular aperture was constantly shrinking to frame a more specific range.While watching the changes in front of the computer, Cheng Jinsong softly said to Xu Rou who was on the phone next to him: "Xiao Rou, go on, hold him steady."

Xu Rou nodded, while continuing to delay time with Geng Qiang.

The aperture has narrowed to the area of ​​the eastern part of the city, but Geng Qiang over there has begun to get impatient: "Why are there so many questions? How long will it take?"

"It will be fine soon," Xu Rou comforted, "Then the next question is..."

"How is it?" Cheng Jinsong asked Shen Hao in a low voice, "How long will it take?"

"About 20 seconds," Shen Hao kept his eyes fixed on the screen without raising his head.

"Xiaorou, wait a little longer, Shen Hao will soon..." Before Cheng Jinsong finished speaking, Xu Rou took off his earphones: "It's over! He hung up!"

Li Jiayu and others who were watching from the side stomped their feet at the same time—it was just a little bit!

Cheng Jinsong quickly looked at Shen Hao: "How is it?"

"I didn't make it to the end, but only determined a general direction," Shen Hao said, picking up the phone beside the table, "Brother, Donghu Park!"

"Geng Qiang hung up the phone ahead of time, and Shen Hao fixed a general location, which is in East Lake Park." Shen Yan hung up the phone.

"East Lake Park? That's in front!" Qin Kai said, Jiang Li nodded and stepped on the gas pedal.

Two cars stopped near Donghu Park.Cheng Haiyang jumped out of the back car and asked, "What, here?"

"Probably." Shen Yan said.

"Damn, it's getting big here, how can we find it with just us?" Cheng Haiyang complained.Donghu Park is the largest park in the city. The whole park is built around the lake, and there is a large forest with winding and complicated tree-lined roads.For this arrest, the serious crime team specially dispatched a few people from the Municipal Bureau, but there were only 12 people in total. It was a bit of a dream to rely on them to find someone in a park with an area of ​​100 million square meters.

Shen Yan also knows that the situation is serious, but there is no other way now, "No matter what, let's go in and have a look first."

Several people walked towards the main entrance of the park——it was early summer evening, the park was open for free, the staff at the ticket office had already left work, and visitors were free to enter and exit the park.This made Shen Yan's idea of ​​"seeking help from the staff" go bankrupt.Shen Yan looked at the huge map of the park at the entrance, and frowned again.

Different from the serious expressions of other people, Qin Kai has been a little absent-minded since getting off the car, and has been looking left and right from time to time.Cheng Haiyang noticed it and couldn't help asking, "I said, what are you looking at?"

"I'm here..." Before Qin Kai finished speaking, he felt someone pat him behind him: "Boy!"

"Ah!" Qin Kai was startled, turned his head and pouted: "Mom, you scared me to death!..."

Standing behind Qin Kai was an old lady in her 60s and [-]s. She was wearing a well-fitting fitness suit and looked quite energetic.The old man has short hair and a round face, with eyebrows, eyes and nose very similar to Qin Kai's.

Qin Kai's mother looked at her son and smiled: "Look at your guts! By the way, didn't you say you worked overtime? Why did you come to the park secretly? Could it be that you secretly dated some girl?..."

"Where?!" Qin Kai didn't know whether to laugh or cry. He pointed to the people around him and said, "Aren't these all my colleagues?! We really have something to do!"

Only then did the old lady notice the crowd of people around Qin Kai, and she was a little embarrassed.The people nearby also knew that this was Qin Kai's mother, and they all greeted her.

Qin's mother nodded to several people, then pulled Qin Kai, and asked in a low voice, "Why did you come to the park?"

"Arrests."

"Ah?! Is there a bad guy here?" After all, the old lady is also the mother of the policeman. Although she was surprised, she didn't cry out. She lowered her voice and asked, "Who is it? How many?"

"Just one, mom, don't ask, you and your group can continue to dance, if you see us later, arrest people and hide away."

Qin Kai didn't want to say much at first, but the old lady frowned when she heard what Qin Kai said just now, as if she had thought of something.She grabbed Qin Kai who was about to leave, pointed to Shen Yan and the others, and asked, "You just want to search the entire park?"

"Aren't we trying to find a way!..." Qin Kai responded casually.

"There is a way!" Mother Qin smiled, pointing to a group of people tens of meters away behind her, "How about we help you find it?"

"Ah?!" Qin Kai turned his head abruptly. He looked at the group of people behind the old lady, and suddenly his head grew dizzy: "Mom, stop making trouble!..."

Perhaps Qin Kai's voice was too loud, causing the people around him to turn their heads.Shen Yan came over and asked, "What's the matter? What happened?"

"Boss is fine!..." Qin Kai quickly waved his hands, but the old lady passed him and said directly to Shen Yan: "Captain Shen? I heard from my son that you are looking for someone in this park? The park is too big, there must not be enough manpower just for you to find it, why don't we help you find it together?"

Shen Yan didn't expect the old lady to have such a proposal. He was stunned for a moment and immediately declined politely: "Auntie, no need. We are going to catch suspects. This mission is dangerous. It is not safe for you to follow us. Besides, we will have someone coming over later , you don't have to worry."

"When your people come over, that guy probably has left the north gate." The old lady waved her hand disapprovingly, "I know you are afraid that Auntie and others will cause trouble, but you don't know, we are all police family members," The old lady said, pointing to the group of old people behind her, "The one on the farthest, her son is from the traffic team in the east of the city; the son next to her who is drinking water is in the east branch of the city; and the one who is talking, her girl is You are from the Publicity Section of the Municipal Bureau." The old lady turned around, "We are a group of people who have a sense of propriety, and we will never make trouble for you. You don't usually come to this park, and you don't know the way. We will guide you, so you can find someone Can be faster, too."

Perhaps because they noticed the movement on Mother Qin's side, those old ladies also came over, and some of them recognized the people on Shen Yan's side, and even got acquainted and greeted them.Seeing the expressions of these people, a group of police mothers guessed that they had taken action. Qin's mother also knew how to measure, so she didn't say anything to the old sisters, but just looked at Shen Yan and waited for her decision.

Shen Yan looked at Mother Qin, then at Qin Kai, feeling a little hesitant.At this time, Jiang Li walked up to Shen Yan's ear and suggested in a low voice: "Boss, I just took a look at it. This park is too big, with many and complicated roads. We are not familiar with the environment, and we may go astray. If we can It’s not bad for someone to lead the way. How about we lead a separate search, and after we find the target, we will concentrate first and then arrest it?”

Shen Yan hesitated for a moment, then looked up at the winding and complicated circuit diagram, and finally nodded.

So the plan was settled. Each of the 12 police officers is paired with a "mother guide" to form 12 groups.Shen Yan clarified the physical characteristics of the suspect with everyone, and emphasized the safety principle again and again, and then let everyone set off.

Cooperating with Shen Yan was the mother of a policewoman. The old lady didn't know if she had nothing to say or she was optimistic about Shen Yan, and asked questions about his parents' family from time to time.Shen Yan responded casually, answering casually, all his attention was focused on observing the passers-by on the road, and at the same time, he had to keep in touch with several other people through the walkie-talkie to understand the situation of each group.

"How, did you find anything?"

"01 has not been found yet."

"02 no."

……

The time passed by every minute and every second, and it was almost seven o'clock in the evening.Just when Shen Yan was worried about whether Geng Qiang had already left the park, a voice suddenly came from the earphone: "I found the target!"

Shen Yan immediately recovered his spirits: "Who found it? Qin Kai, is it you?"

"Yes!" Qin Kai's voice came from the earphones, "I found the suspect in the small square on the east side of the lake, where the open-air movie is."

"Okay, you keep an eye on him first, we'll go there!"

Under the leadership of his aunt, Shen Yan quickly rushed to the small square. This small square is located on the east side of the lake, and the area is not too big. You can see a lot of people gathered in the square at the moment from a long distance away.The small square faces water on one side, roads on two sides, and a small forest on the north side.At this moment, Qin Kai was hiding in the woods to observe the situation.Beside him, several other team members have also arrived.

Shen Yan quickly came to Qin Kai's side and asked, "How is it, where is it?"

"It's right behind the group of people in the square, near the flower bed."

Shen Yan took out the binoculars, looked in the direction of Qin Kai's finger, and found Geng Qiang in the crowd.The man was sitting in the open space in front of the flower bed, looking up at the movie like everyone else.

Seeing Geng Qiang appearing here, a trace of worry and doubt arose in Shen Yan's heart - he went out to watch a movie alone, what about the child?Could it be that he has already sold it? ...

At this time, Qin Kai said in a low voice: "Boss, how do you catch him?"

Shen Yan came back to his senses, the current situation is really a bit tricky, because during the movie show, many people gathered in the small square, at least more than 100 people, and everyone sat very close to each other. Once the suspect resists arrest and resists, it is very likely that Injure the masses by mistake.Moreover, the small square is empty and open, and there are no obstacles around. How to get close without being noticed by the suspect is also a problem.

"There are so many people, why don't we do it after the show ends." Cheng Haiyang suggested.

Shen Yan shook his head: "I don't know how long it will be until the movie ends, and when the time comes when everyone gets up together, it's easy to lose the target."

"Then what should we do? Let's think of a way to lure him out?" Cheng Haiyang said again.

Shen Yan still shook his head—it was too difficult to prevent the suspect from becoming suspicious.

Just as everyone was staring at the small square and frowning, Qin Kai's mother tugged at her son again: "Son, come with me for a walk."

"Mom, what do you want to do?!" Qin Kai immediately became alert, "Didn't I tell you that you can't join in the fun when you are arrested?"

"Hey, you guys go over there, can the scoundrel not be suspicious?" Mother Qin rolled her eyes, "But if my old lady suddenly sees a movie show while walking with her son, just go over there. Look at it for a while, isn't it so strange?"

Qin Kai's mother's words reminded everyone.It is true that it is too easy for them to attract attention when they go alone, but if there are a few more old ladies, they will not be so conspicuous.It's just that this will put the old people in a dangerous place, and Shen Yan doesn't want to take such a risk.The old lady seemed to see his doubts, and said, "Don't worry, I can find a way to escape before you catch the thief. With so many of you, you still can't hold that thief?! Besides, if that guy is really reckless If he takes people as hostages, it will be more troublesome for him to catch others, and others may not know how to keep calm as we do!"

There is some truth to what the old lady said.Everyone looked at each other, and finally focused on Shen Yan.

Shen Yan looked at Qin's mother who was full of confidence, then looked at the other side of the square, hesitated for a while, and finally nodded.

After some research, the final plan was that Shen Yan, Jiang Li, and Qin Kai would take the two old men there, while Cheng Haiyang and several other police officers would disperse around the square to prevent the suspect from escaping in advance.Soon, Cheng Haiyang's side was already in position, and Shen Yan repeatedly emphasized the precautions to Qin's mother and another old man who participated in the operation, and then led them to the small square.

The first ones to set off were Qin Kai and Qin's mother. The mother and son pretended to be walking by the side of the road and accidentally found a movie. They naturally sat in front of the suspect on the left.Afterwards, Jiang Li set off. With a cigarette in his mouth, he pretended to be a passerby taking a walk, and unknowingly stood still behind the suspect on the right.People came and went in the small square all the time, and from time to time someone walked into the crowd and sat down, so there was no doubt about the whereabouts of the three of them.

"Auntie, let's go." Shen Yan said to the old woman beside him.

The old man nodded and stretched out his hand to Shen Yan naturally.Shen Yan supported the old man's arm and walked slowly towards the suspect.

"Hey, there's a movie, boy, let me borrow some light." The old lady is worthy of being a police mother, and she acted like that, she squeezed into the crowd without much effort, and successfully led Shen Yan to the intended target ——The suspect's rear left.

All three are seated.

In order to prevent the target from being alerted, several people did not take action immediately, but watched the movie like everyone else.About 2 minutes later, Qin's mother, who was at the front, suddenly leaned over and coughed, and successfully issued a warning signal.

Shen Yan quietly glanced at Jiang Li who was not far away, and the latter gave him a look back.

Qin Kai's mother coughed badly, Qin Kai also seemed to notice her mother's discomfort, got up and supported her as if she was about to leave.The moment he turned around, he looked back inadvertently, and gave a look to the two people in the back row——

"action!"

Accompanied by a loud shout, Qin's mother, who had been walking slowly just now, suddenly and swiftly hid aside, while Shen Yan and the other three jumped into the middle at the same time, and pressed Geng Qiang to the ground with lightning speed!

Caught!
