Most of the 32 fingerprints belong to Tang Hao himself.
There are 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 only released two years ago.
The fingerprints of a man with a criminal record turned up on Tang Hao's bicycle.
Obviously the other party is 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 preparations and is now working on Analyze the base station connection we got from the mobile company."
"Let's go and take a look."
conference room.
When Lu Chuan came in, he saw many computers and devices for receiving satellite signals.
"Corps."
A total of four people from the technical support team came over, all from the branch.
The person in charge was called Zheng Jun: "Our preparations here have been completed."
"Just wait for the robber to call Tang Guojin, and we will be able to 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. Location.”
“Oh? Where is the location?”
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 calls."
"We compared the timetable of the other party's calls to Tang Guojin."
“Then these base stations were marked.”
Zheng Jun introduced, and the staff nearby followed suit.
On the projected map, six red dots appeared one after another.
"Look, Lu Lu, 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 base station on the roof of Building 3 of Haiyang Community."
"The other party This phone number has been activated since New Year's Day, and a total of 35 calls have been made."
"Among them, 18 have been connected to the base station in this ocean community."
" Base stations are also around this base station.”
Those who engage in technology are different from others.
When Zheng Jun was giving an introduction, the 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 Lie, 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 quite obvious. "It is very likely 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, with a very large population and a relatively large coverage area."
"There are three optical communication base stations in this community."
“The most connected base stations to the kidnappers’ mobile phones are the base stations on the roof of Building 3.”
“So it is basically certain that the kidnappers 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 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 does not understand the calls on the mobile phone, Principle, then the other party should be in the 4 buildings circled.
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, it is possible that they deliberately found a place to make the call.
The purpose is to confuse the police and prevent yourself from being discovered.
So 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 his release, there has been no Find a job.”
"Living in the house left to him by his parents, in... Unit 301, Building 2, Haiyang Community."
Ocean Community again? !
Conference 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 Haiyang 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 person also lives in Haiyang Community."< br>
“Let’s discuss and share our opinions.”
“Army Corps, I think we can now carry out key deployment and control of the ocean community.”
Chen Jiang was the first to express his opinion: “ From two aspects, the possibility of the other party being 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 the Ocean Community directly. The other party is likely to be there. Inside Cui Kai's home."
Sun Biao nodded: "I agree with Lao Chen's opinion, and focus on the Haiyang Community."
"But whether to arrest him or not, we need to go further. We need to be more careful when determining the specific location of the other party.”
“I think we should wait for Tang Guojin to raise cash first.”
"Tang Hao should be safe until the other party gets the money."
"We have relatively plenty of time."
"My opinion is to get the cash before the other party ""
"This can still paralyze the other party and make the other party think that Tang Guojin did not call the police, which can make the other party relax their vigilance to a certain extent."
"In addition, no matter whether the other party is. Whether one person kidnapped or multiple people committed the crime, if the other party sends someone out to get the money, then the guarding force of Tang Hao will definitely be relaxed, which will also facilitate our rescue."
Wang Zhaokai then spoke: "Lao Sun's idea is more appropriate."
"I also think this is more appropriate. The information we have at present is not enough to be 100% sure that the place is Cui Kai's home."
“I suggest checking how Cui Kai and his family have recently bought groceries or ordered takeout.”
“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)
