Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Most of the 32 fingerprints belong to Tang Hao himself.

There were also several fingerprints belonging to Tang Hao's friends, people who went cycling with him.

In addition to these, Lu Chuan also found two unfamiliar fingerprints.

One of them, the comparison was successful.

Cui Kai, a native of Haizhou City, was imprisoned for four years for robbery and was released two years ago.

The fingerprints of a man with a criminal record turned up on Tang Hao's bicycle.

It was obvious that the other party was the person who kidnapped Tang Hao or one of them.

The other fingerprint did not hit the target.

But it doesn't matter now. Cui Kai has been identified, so the detection of the case can be said to be just around the corner.

"Check this person's background."

Lu Chuan handed over the relevant information about Cui Kai to Wang Zhaokai.

"Yes."

"How are the preparations in the conference room?"

"The technical support team from the branch has completed the preparation work and is now analyzing the base station connection situation we obtained from the mobile company."

"Let's go over and have a look."

meeting room.

When Lu Chuan came in, he saw many computers and devices for receiving satellite signals.

"Army."

A total of four people came from the technical support team, all from the branch.

The person in charge called Zheng Jun: "Our preparations here have been completed."

"Just wait for the robber to call Tang Guojin, and we can track the other party's location."

"In addition, based on the information provided by the mobile company, we roughly estimated where the other party was hiding."

"Oh? Where is the location?"

Zheng Jun waved his hand, and the staff next to him turned on the projection.

What appears is a high-definition map of Haizhou City.

"Judging from the base station connection status obtained from the mobile company, there are a total of 6 base stations connected by the other party's call."

"We compared the schedule of the other party's calls to Tang Guojin."

"Those base stations were then tagged."

Zheng Jun introduced it here, and the staff next to him followed.

Six red dots appeared one after another on the projected map.

"Look, Army Corps, these six base stations are distributed around the People's Square in the High-tech Zone."

"The base station with the most connections is the one on the roof of Building 3 in Haiyang Community."

"The other party started using this phone number on New Year's Day and made a total of 35 calls."

"Among them, 18 channels are connected to the base station of this ocean community."

"The remaining base stations are also around this base station."

Those who engage in technology are different from others.

When Zheng Jun was making an introduction, four or six red dots on the projector gradually enlarged.

And the number of calls made by a mobile phone connected to each base station is marked.

The most conspicuous one is the base station on the roof of Building 3 in Haiyang Community.

It accounted for more than half of the 35 phone calls.

"Lu Qiang, this community... is right behind the Hilton Hotel."

Chen Jiang lives near this community and is familiar with the situation there.

The current situation is actually more obvious. "It's possible that the kidnapper lives in Haiyang Community?"

"It should be about the same."

Zheng Jun walked to the projection: "There are a total of 27 buildings in the Haiyang Community. There are a lot of people living there and the coverage area is relatively large."

"There are three optical communication base stations in this community."

"The base station most connected to the kidnapper's mobile phone is the base station on the roof of Building 3."

"So it is basically certain that the kidnapper should live near Building 3."

"We checked the coverage area of ​​the base station in Building 3 against the map. There are 4 buildings in total."

"If the murderer did not deliberately make a phone call in this place, it means that the other party is likely to be hiding in these four buildings."

The situation Zheng Jun mentioned means that if the kidnapper doesn't understand the working principle of mobile phone calls, then the other party should be in the four designated buildings.

However, if the other party knows or knows that the police can lock the approximate location of the mobile phone based on the communication base station, they may have deliberately found a place to make the call.

The purpose is to confuse the police and prevent themselves from being discovered.

Therefore, we cannot say with 100% certainty that the robbers must be in these four buildings in Haiyang Community.

Fortunately, in addition to this, Lu Chuan also had another important clue.

"Team Lu, Cui Kai's information has been found out."

Just at this time, Wang Zhaokai came back.

"Cui Kai, male, 34 years old, was imprisoned for robbery six years ago and was sentenced to four years. He was released after serving his sentence two years ago."

"After being released, I haven't found a job."

"Living in the house left to him by his parents, in... Unit 2, Building 301, Ocean Community."

Another ocean community? !
meeting room.

Lu Chuan hosted an analysis meeting.

"Judging from the current situation, the technical support team most likely believes that the other party is in the ocean community."

"On the other hand, the fingerprints of a person named Cui Kai, who has a criminal record, were found on the bicycle Tang Hao was riding."

"Coincidentally, the other party also lives in Haiyang Community."

"Let's discuss and share our opinions."

"Army Corps, I think we can now focus on controlling the ocean community."

Chen Jiang was the first to express his opinion: "From two aspects, the possibility that the other party is in Haiyang Community is very high."

"And the place where Tang Xiaoyu was found after she was kidnapped is at the Hilton Hotel, and the Ocean Community is behind the Hilton Hotel."

"So my idea is to attack Haiyang Community directly. The other party is likely to be in Cui Kai's home."

Sun Biao nodded: "I agree with Lao Chen's opinion and carry out key deployment and control of Haiyang Community."

"But whether to arrest or not, we need to further determine the specific location of the other party, and we need to be more cautious."

"I wonder if we should wait for Tang Guojin to raise cash first."

"Tang Hao should be safe until the other party gets the money."

"We also have relatively ample time."

"My opinion is to wait until the other party takes cash."

"In this way, you can still paralyze the other party and make the other party think that Tang Guojin did not call the police. To a certain extent, it can make the other party relax their vigilance."

"In addition, whether the other party is kidnapping by one person or multiple people committing the crime, if the other party sends people out to get the money, then the power of guarding Tang Hao will definitely be relaxed, which will also make it easier for us to carry out rescue."

Wang Zhaokai then spoke: "Lao Sun's idea is more appropriate."

"I also think this is more important. The information we have so far is not enough to be 100% sure that the place is Cui Kai's home."

"I suggest you check how Cui Kai and his family have purchased groceries or ordered takeout recently."

"It's not too late to take action after further confirmation."

"The other thing is that Tang Guojin needs to cooperate, for example, let the other party get part of the cash first." (End of Chapter)
