America's Big Hero

"Very good!" Sean hung his lips, "Can you monitor their phone calls?"

"Technically yes, we have already informed the personnel at Wanwan, and we will monitor the recording later."

To put it bluntly, this practice is illegal and violates human rights.

According to the law, the police should submit an application to the court after confirming that the other party is a suspect, and then the court will issue an approval document before they can monitor the phone.

Even so, it can only be monitored by the police alone, and it is impossible to extract data directly from the communication company.

In theory, the communication company would never cooperate.

Information security is the foundation of communication companies.

Of course, this is in theory.

It is illegal for Umbrella to do this, Sean knows it, Masao Iwasato knows it, and the communication company knows it, but so what!

Who can pursue it?

Who dares to pursue it!

"Very good!" Sean clapped his hands lightly, and said with a confident smile, "Actually, solving the case is very simple. I don't know what the police do, but it's never been difficult for me. .”

"As long as you walk by, you will leave traces!"

"The phone number on Hong Kong Island that he was talking to is most likely the mastermind. The negotiator is not himself. It can be seen that this guy is quite cunning. However, no cunning fox can escape the hunter."

"People's behavior is never isolated, and they all have their own behavioral logic and inertia. He can set up separate negotiators. From this, it can be inferred that the operator is most likely not the person himself, and the detainees will not be the person himself. It's pretty clean."

"Hehe, what's the use of it." Sean sneered, "If you are caught, everyone will be caught. Setting up so many groups is purely taking off your pants and farting!"

"However, judging from the way he behaves, he has a bureaucratic taste. He was not really a police officer before, but now he can be sure of it with a high probability."

"Have you got the call record of the mastermind?" Sean asked with a smile.

"I got it. I found all the call records of the last month, and we sorted them out." A long call record printed out by a fax machine was handed to Sean.

Sean took a cursory glance, picked up a pen and began to divide, firstly distinguishing today, yesterday and the past, into three parts.

The point is yesterday, the kidnapping happened yesterday.

According to Wang Dehui's itinerary obtained by Wang Dehui's secretary, it is certain that he was kidnapped on the way back to the villa on the top of the mountain. According to the distance, the time of the kidnapping can be calculated, and the error will not exceed 10 minutes.

The time of Wang Dehui's departure began to be substituted into the call record, and Xiao En circled a range with a pen.

Looking at this circle again, there were a total of 12 calls and calls, and only 12 numbers appeared in these 4 times. Sean distinguished them according to the order of appearance, and divided them into ABCD.

A appeared first, and there were 6 times in total, all of which were dial-in.

B appears second, 3 times, once dialed out, twice dialed in.

C appears third, 1 time, dialed out.

D appears last, 2 times, one for dialing in and one for dialing out.

Substituting the calculated kidnapping time into it, it was found that A appeared twice, with a very short time gap, and never appeared again.

All BCDs appear after this time node.

Sean looked at the phone number, and a scene simulation automatically appeared in his mind.

Team A monitored Wang Dehui's whereabouts. They followed Wang Dehui all the way from his appearance, called the mastermind to report all the way, and followed him all the way to Shanding Road.

Group B received a call from the mastermind at this time and was ready to act. After the robbery was completed, the mastermind was notified immediately, and they went straight to the scheduled meeting point, and then called the mastermind again.

C and D are not yet 100% sure.

However, this did not trouble Sean.

"Immediately ask the communication company to send the call records of these 4 phone numbers." Sean raised his head and said.

Ten minutes later, the call records of the four phone numbers ABCD appeared in front of Sean.

Sean was the first to pick up C's call records and looked at them. There were no more call records with the mastermind, including ABD. It can be temporarily ruled out that he participated in yesterday's kidnapping operation, and it is very likely that he has nothing to do with this gang.

Looking at D again, after substituting the time when Umbrella released the rumor yesterday, he immediately found the call records with the mastermind. Xiao En felt that this D was probably responsible for detaining Wang Dehui.

After the mastermind knew the threat of the umbrella, he immediately called to confirm.

Assuming that D is the custody group, then, looking at the call records of the mastermind, a dial-in to D is similar to that of B, so it can be judged that D is indeed responsible for receiving people in custody.

And the call in later... Xiao En squinted his eyes and thought for a while. The mastermind was so cautious, would he allow the action team to know where Wang Dehui was detained?

Sean doesn't think so.

Therefore, the last call was made by members of Group D reporting to the mastermind that they had arrived at the place of detention.

After going through the operation process of yesterday's kidnapping in his mind, Xiao En pulled a piece of paper and quickly drew it.

First, Zhong Weizheng was drawn in the middle, and then the Shangwan Bay Negotiation Team, Hong Kong Island Action Team, Hong Kong Island Detention Team, and Hong Kong Island Observation Team were drawn on the top, bottom, left, and right sides, and the phone numbers were marked respectively.

Finally, a robbery action flow was written below.

After writing it, he handed it to Norris next to him, and Norris hit it on the wall with a projector.

"Let's see if you have any other opinions, and look for any loopholes." Sean clapped his hands without explaining.

Torre and the others didn't ask any questions, but the three people who joined DSS later asked why Sean made such a judgment. They were in charge of protection work, and from the perspective of protectors, they also had research on the kidnapping case.

Sean explained them one by one, and no one could find anything wrong with them.

What is the originator of robbery.JPG

No matter how complicated you are, in the eyes of the originator of the Dao of Tribulation, it is true at a glance!

"Okay, since everyone has nothing to say now, let's assume that this is true, the technical team, can you locate these phone numbers." Sean looked towards the communication expert.

"It can only be vaguely positioned." The communication expert said.

"Hey, isn't it possible to triangulate through multiple signal base stations?" Sean looked puzzled, he remembered that this is how the future generations are positioned.

"Uh...it's a good idea." The communication expert said after organizing the language: "Theoretically, it can be realized, but it needs to rewrite a set of programs for the communication company."

"Currently, communication companies do not have a business that needs to locate users, so, as far as we know, it is not currently possible."

Sean nodded, well, since there is no money to make, the communication company will naturally not consider such things as positioning, which is reasonable.

"So, such a program cannot be developed in a short time?"

"Yes, but..." The communication expert thought for a while and said, "It can be vaguely positioned."

Sean became interested and raised his hand to signal.

"We can know which base station this number is connected to, and then turn off this base station to see if it will be connected to other base stations. If so, it means that the location of this number is within the common coverage of the two base stations. "

"In this way, an approximate location can be vaguely determined. The only problem is that the population density on Hong Kong Island is very high, and the effect of fuzzy positioning is really not very great."

"No, no, no!" Sean raised his hand to prevent others from speaking, his mind spinning rapidly.

After a while, Sean snapped his fingers with a 'snap', "I have a solution, so let the communication company immediately locate the approximate location of D."

When the order was issued, Boss Li's communication company naturally cooperated fully, and the news was delivered within a few minutes.

"Boss, the China Unicom base station of this mobile phone number is at sea. The coordinates of the base station are here. The coverage area is 20 kilometers." The communication expert picked up the ruler and measured it on the map on the desktop, then lightly tapped a red dot on the map, and then Draw a circle with a compass.

"Look, don't you know where the kidnappers hid him!" Sean laughed.

Saying that, Xiao En looked at the communication records of Group B, which is the action group. The time when he called back to the mastermind for the first time should have just completed the kidnapping. After calculating the difference between the second communication and the third communication, Xiao En raised his head and said, "Look for the police on Hong Kong Island, ask for the average speed of cars in the city during this time period, and then calculate, what ports can be reached from the Peak Road during this period? Then exclude those In a public port with a large number of people, there is a high probability that they will hand over personnel at the port."

With an order, a group of people took action immediately, substituted the data provided by the traffic police into the establishment, and took the map of Hong Kong Island to start calculating road by road.

Soon, the result came out, "Excluding the big port, there is also a remote private port, an abandoned port."

"Immediately send someone to investigate. The handover location is at the port. Wang Dehui's car is missing. I guess it was driven directly into the sea. Find the car for me!" Sean said emphatically, slapping the table!

Chapter 484:

Sean previously mobilized 300 people from other parts of Southeast Asia, and it was used at this time.

Mobilized dozens of people, divided into several waves, and drove a small boat to explore. After about two hours, the news was sent back. Sure enough, Wang Dehui's vehicle was found underwater.

Sean seemed very happy, which verified that his estimated kidnapper's course of action was correct.

"It is impossible for these gangsters to buy or rent a yacht as a tool to detain Wang Dehui at sea. It is most likely to be the most common fishing boat on Hong Kong Island, which also makes it convenient for them to stay at sea for a long time."

"Ask the coast guard or the fishery administration, what size and speed are the most common fishing boats on Hong Kong Island?" Sean ordered.

Not long after the news came back, Sean substituted the time of the two calls made by the custody team into the calculation, and immediately got the approximate location of the fleet's last call on the map.

This area coincides with the coverage of the marine base station provided by the communication group just now.

Sean was very happy to get this result, which shows that the custody team did not make large-scale movements within 24 hours, which is good news.

The only problem is that this range is still very large, and Hong Kong Island is one of the busiest ports in the world. There are too many ships in this range, and there is still no way to pinpoint which ship it is.

But don't worry, there is always a way.

"Call the Hong Kong Police and tell the Coast Guard not to patrol in this direction for the time being, so as to prevent... No!" As he spoke, Xiao En suddenly paused. The mastermind was from the police. Will it arouse his vigilance?

"Let the coast guard patrol as close to the shore as possible. The opponent's ship is likely to be close to the open sea. Don't disturb them. Once they escape, it will be troublesome to find them again."

"Okay," Norris agreed.

Of course, the police on Hong Kong Island are not Xiao En's subordinates, and theoretically there is no possibility of ordering them to cooperate, but the Governor of Hong Kong doesn't think so.

In the eyes of the governor, Sean is a big trouble, a big trouble that the Major government can't do anything about, and he doesn't want to make Sean unhappy because of such a small matter.

Besides, Wang Dehui's kidnapping case has had a great impact on Hong Kong's wealthy, and the police don't have the guts to jump out and sing a different tune at this time.

After a while, Norris came back with a fax in his hand, "I have told the police, this is the list of retired police officers they compiled according to your request, and according to the screening criteria you provided, they divided people into ABCDE various files."

As he spoke, he handed the fax to Sean.

Sean looked down and saw that there were more than 40 people in file A, and there were more than 300 people in file B. He didn't bother to look at it later, and just threw it on the table, "What a fucking waste!"

"Let them call to verify, and give me this kind of thing for a good use!"

Norris thought for a while and said, "I guess the police on Hong Kong Island don't know how to verify it."

Sean rolled his eyes, stretched out his hand, and Norris immediately handed over the phone, "Hello, Mr. Li, I'm Sean."

The current Hong Kong Island elder brother, surnamed Li Mingjun Xia, is the first Chinese director in history.

After exchanging pleasantries and compliments, Sean finally got to the point, "My idea is to contact the people on this list by calling a landline, whatever the name is, insurance sales, the police's care for retired police officers, the city government's initiative The relevant investigations, you can find it in name, you only need to determine the approximate location of the target."

"The landline has a location report when it is installed. Even if it moves, the distance will not be too far. Understand what I mean."

Xiao En sorted out the kidnapping process and group status of the kidnappers through the phone numbers and traffic records used by the kidnappers. Wang Dehui's vehicle was also found.

The approximate range of the kidnappers is now being determined by the cell towers the kidnappers are using to connect to.

The police only need to use the exclusion method to narrow the scope again, and those who cannot be contacted are also suspected.

"Understood, understood." Chu Li reacted instantly, and at the same time he agreed without hesitation, but at the same time he couldn't help but click his tongue secretly.

After hanging up the phone, Li Chu clicked his tongue twice. It seems that this super rich man is really not fooling around, he has a lot of tricks!

Although the resources Sean mobilized are a bit exaggerated, it is not something that the Hong Kong Island police can do to make the two major communication companies of Wanwan and Hong Kong Island cooperate regardless of the legal terms and rights.

But there is no problem at all.

Why do the super rich have a clear idea of ​​solving crimes?

What kind of experience made a super rich man even more proficient in case detection than the police?

Behind all this is the distortion of human nature or the loss of morality?

Chu Li didn't understand this point.

Shaking his head and pressing the communicator to call the secretary over, the task still needs to be explained, but he didn't say the specific reason.

After assigning tasks to the police, Sean brought his attention back again.

There are two goals that need to be achieved at present, find Wang Dehui and find the mastermind, either goal can be achieved.

Sean thought about these two goals for a long time, and finally came up with a solution.

"Is it possible to determine the approximate location of the mobile phone number by using two or three adjacent base stations?" Xiao En reconfirmed with the communication expert.

"Yes."

"Well, let the communication company keep an eye on it. I guess this guy will come back tonight. Once the mastermind returns here again, let me know." Sean began to assign tasks.

"In addition, you should divide into several groups, bring the signal shielding equipment into the determined range to try, and try to eliminate it bit by bit. Although it is a bit troublesome, try to lock its position in a small range."

As soon as Xiao En said it, the people below understood that they entered with a signal jammer, and as long as they found that the connection between the mastermind's mobile phone number and the base station was cut off, it meant that the other party was already within the shielding range.
