Diary of a Criminal Investigator

Chapter 742: The Final Hour, Deal Begins

This idea, in fact, Lu Chuan had considered before.

However, for safety’s sake, he ultimately didn’t follow through.

Unlike booking a room at the Hilton Hotel to monitor the opposite side.

Booking a room only costs money and doesn’t require the hotel’s cooperation; Lu Chuan can handle it himself.

But retrieving the Hilton Hotel’s surveillance footage would definitely alert a lot of people.

There’s certainly a reason why they placed Tang Xiaoyu in the Hilton Hotel.

Lu Chuan suspects that it’s very possible one of them works at the Hilton Hotel.

So if they rashly retrieve the hotel’s video and the other party finds out, then Tang Guojin’s report becomes undeniable.

By then, if the other party acts in desperation and kills Tang Hao, things would become difficult.

The biggest fear in kidnapping and ransom is that they might kill the hostage.

"We can’t retrieve the video; the other party is currently in a highly tense state."

"By tomorrow morning, Tang Guojin’s side will have the cash ready."

"This time, the amount requested is very large, and Tang Guojin’s side can only divide the cash into multiple batches to be placed at the designated location by the other party."

"This way, their forces will be dispersed, giving us a much larger chance to capture them from different directions."

"Also, before the other party gets the money, they are most afraid of Tang Guojin reporting to the police, so once they get the money, they will let their guard down."

"Since Tang Hao is safe, we can’t take any risks."

"Everyone get a good rest tonight, tomorrow is the real battle."

After a day and a half of investigation, Lu Chuan can now basically confirm that the kidnappers should be in the Ocean District, in Cui Kai’s house.

According to Tang Xiaoyu, there should be 5 of them, four men and one woman.

During this time, they ordered 6 portions of takeout.

kidnappers plus Tang Hao, exactly 6 people.

Of course, besides these people, the ones monitoring Tang Guojin’s family are not among them.

The residential area where Tang Guojin lives is a villa district he developed and invested in.

The security situation is actually very good; it’s very difficult for strangers to get in.

Since it’s not someone from outside monitoring Tang Guojin’s house, it has to be someone from within the community.

But as to who it is, Lu Chuan has not conducted an in-depth investigation.

It could be a security guard, or a cleaner, anyone is possible.

At this time, Lu Chuan cannot alert the enemy.

As long as they make the transaction, once they start taking the cash and let their guard down, with weak defenses, they can begin to act.

Time quickly reached the morning of the 3rd day.

Tang Guojin’s living room was already filled with cash.

This morning, Tang Guojin contacted the other party.

All the cash was packed into 20 travel bags, each containing 5 million yuan.

Five million in cash is actually much heavier than the average person imagines.

A single 100-yuan bill weighs 1.15 grams; 5 million in cash weighs 115 jin.

And that’s the weight of new bills; the kidnappers demanded used bills, which weigh even more.

So these 20 travel bags, each one weighs about 130 jin.

jin in weight is already the limit of what an average person can carry.

Of course, the "average person" here doesn’t include Tang Guojin.

"I need to find someone to help!"

On the phone, Tang Guojin was communicating with the kidnappers: "Each of these bags weighs over 100 jin, I can’t carry them, and neither can my wife or daughter."

"Now you want me to move this money to the designated place, I definitely can’t do it, I need someone to help me."

There was a moment of silence on the other end of the line.

A mechanical voice came through moments later: "Wait for my call."

Then, the call ended.

This time, the call lasted quite long, over three minutes.

Criminal Investigation Team.

The moment the kidnappers called Tang Guojin, the technical support team began pinpointing the location of the call.

"It’s at the Ocean District, on the top of Building No. 3’s base station!"

The moment the phone connected, the technical support team had already identified the base station the call connected to.

As usual, it connected to the base station on top of Building No. 3 in the Ocean District.

This means the other party is within the Ocean District.

Next, it’s about using calculations to determine the exact distance from the base station to them.

For a signal base station, all mobile phones connected to it have a sequential distance order.

This distance order will cause call delay.

And by the length of the delay, one can calculate the distance of the mobile phone from the signal base station.

Of course, those on the call aren’t aware of it, as the time length is calculated in milliseconds.

This magnitude of call delay can’t be perceived by humans, but computers can.

However, the calculation is quite large, so a longer continuous call time is needed to accurately pinpoint their location.

Typically, it requires at least a minute of continuous conversation.

During the time Tang Hao was kidnapped, the kidnappers contacted Tang Guojin multiple times.

But the call lasted this long, this is the first time.

"Thirty meters! The distance is thirty meters!"

After the technical team came to the calculation result, Chen Jiang hurriedly took the map to measure.

Starting from the top of the signal base station, measure thirty meters.

It just covers Building No. 2!

"Captain Lu, they’re in Building No. 2!"

"Good!"

The takeout records from the past two days, along with this positioning of the call, and the information provided by Tang Xiaoyu.

Multiple locks confirm the target as Building No. 2.

Meanwhile.

Ocean District Building No. 2, Unit 3, Room 301.

Cui Kai and the five others were gathered together, discussing.

"What should we do? With that much money, there’s no way that Tang guy can carry it."

"I suggest letting Old Song go to collect the money and give the Tang guy a hand."

"Are you crazy? Old Song going will definitely expose us."

"And if he helps with the money, who will monitor Tang Guojin inside the District?"

"What if they call the police?"

"Call the damn police, that old man only has one son, isn’t he afraid we might kill him?"

"Besides, last time when we kidnapped his daughter, you all saw it, calling the police for what?"

"No way, Old Song can’t show up. If he goes, we will be exposed, and even if we get the money, once Tang Guojin calls the police, Old Song will lead them right to us."

"Let the Tang guy find someone himself, we still can’t show ourselves."

"Alright, damn it, should have kidnapped his wife instead. If Tang Hao went to deliver the money there’d be no problem at all."

"Enough, stop babbling, hurry up and call Tang Guojin, a hundred million! Except for Old Song’s share, how much do we each get?"

"It’s a windfall! A windfall!"

Ring ring ring!

At Tang Guojin’s house, the phone rang.

Tang Guojin took a deep breath and picked up the phone: "Hello..."

"You find someone yourself to deliver the money, but whatever you do, don’t call the police, otherwise prepare to collect your precious son’s body! Got it?"

"I want to video chat with my son."
