Rebirth 2014: I, the King of Criminal Investigation

Chapter 380 Tracking is also a technical skill
After receiving a reply from the officers in Group Four, Yu Dazhang continued to issue orders:

"The rest of the groups follow behind the fourth group, and be careful to keep your distance."

At his command, the various groups sprang into action.

Yu Dazhang remained where he was. After the van drove away, he checked the direction and then said to Qi Fang, who was sitting in the driver's seat:
"Let's go, just follow at the back."

There aren't any particularly effective methods for vehicle tracking; the most common approach is to frequently switch vehicles.

Currently, including his SUV, he owns a total of eight private cars.

This quantity is such that even repeated tracking will not be detected by the other party.

Because each car needs to follow for at least fifteen minutes, it will take two hours after all eight cars have followed the route.

At this moment, the first car reappeared, but the people in front had long forgotten that such a car had ever appeared.

Moreover, with other vehicles on the road, it becomes even more difficult to distinguish them.

Before taking action, Yu Dazhang had considered installing GPS tracking on Zhang Sen.

After discussion, the proposal was rejected.

GPS locators need to receive and transmit information, so they emit specific frequencies when in operation.

These signals can be captured using a signal detector to determine the GPS location.

These people likely possess such equipment, so for safety reasons, the final decision was to use only the most basic method: tracking.

Yu Dazhang is currently experiencing a mixture of worry and excitement.

What I'm worried about is Zhang Sen's safety.

Zhang Sen is currently completely out of contact. All that is known is that he is in the other party's van, and nothing else is known.

If the other side resorts to underhanded tactics and lacks sportsmanship, there's simply no way for us to respond.

The exciting part was that they successfully lured out the criminals who were lurking in the train station.

He had been unsure whether Zhang Chao and his men had evacuated their troops, but now he was finally relieved.

This is undoubtedly a major development in the entire case.

If all goes well, they will be able to follow the clues and find the underground prison directly.

Two and a half hours later.

"The target vehicle drove into a farmhouse in the suburbs."

After listening to the report over the walkie-talkie, Yu Dazhang pondered for a moment and then gave the order:
"Continue to observe, remain concealed, and notify us immediately if anything happens."

This perfectly matches what Fang Peng had told us before.

Five years ago, after Peng was kidnapped, he drove for more than two hours, and then switched to a truck halfway through the journey.

Judging from the travel time, they did not change their transit points in the past five years.

Or it may have already been moved, but the location is not far apart.

"Arrest them."

At this moment, Team Leader Hua was getting restless. He patted Yu Dazhang on the shoulder and said:
"First, we'll take them under control, then we'll interrogate them on the spot. We should be able to find out where they'll meet next."

In reality, he was worried about Zhang Sen's safety.

In his view, the current actions are gambling with the lives of police officers.

Yu Dazhang was well aware of the seriousness of the matter.

However, he currently has no other options.

"What if they refuse to confess?" Yu Dazhang asked, frowning.

"This possibility cannot be ruled out."

"Also, if we rush in now, the people inside will likely notify Zhang Chao and the others immediately."

He paused briefly, then added:

"And their methods of evading the police are not limited to just making phone calls."

He then recounted how Qi Fang had raided Zhang Chao's residence in Liancheng.

"Using a network of surveillance cameras to set a trap for the police?" After hearing this, Captain Hua's expression also became serious.

"We will definitely arrest them," Yu Dazhang continued.

“If I find that things are getting out of control, I will immediately order the arrest. I know Zhang Sen, and he certainly doesn’t want us to give up halfway.”

He believes the Chinese team understands the stakes involved.

The reason why the team was in such a hurry to make the arrest was because they were worried about Zhang Sen's safety.

A person who can become a deputy chief of staff will naturally prioritize the safety of police officers.

A dead end can be found again, but if a police officer's life is in danger, it will be too late to regret it. So what Captain Hua said is understandable.

Yu Dazhang was certain that Zhang Sen would not encounter any unexpected events.

Those people's goal is to exploit mentally disabled people for financial gain, and they are unlikely to harm those they kidnap easily.

Moreover, Zhang Sen didn't bring anything with him, not even a second-hand Nokia phone that he bought in another city.

It doesn't even have a camera function. You can search it up anytime, and you'll find that everyone is silent.

"Okay." Team Leader Hua paused for a moment, then nodded in agreement.

He knew in his heart that the case had indeed reached a critical moment.

This is a golden opportunity; if we miss it this time, it will be almost impossible to find another chance like this.

Twenty minutes later.

"The van is coming out; judging by the direction, it's heading back."

Upon hearing the report on the walkie-talkie, Yu Dazhang hesitated for a moment before picking it up:

"Five groups follow up. The local police will contact you later. Remember, you must not act alone."

"Understood," the officer from Group Five replied quickly.

Putting down the walkie-talkie, Yu Dazhang looked at Team Leader Hua:

"Our police force is limited, so we contacted the local police for assistance in the arrest."

The three kidnappers cannot be let go, but to ensure the success of the arrest operation, it is necessary to seek assistance from the local police.

When Hua borrowed the car, he had already contacted the local police, so this task was naturally assigned to him.

What follows is a long wait.

Yu Dazhang leaned back in his chair, seemingly resting with his eyes closed, but in reality, he was assessing what might happen next.

According to Fang Peng's confession, when he was arrested, there were six or seven people in the van, including himself.

In other words, a certain number of people need to be gathered before sending people to the underground prison.

There is another possibility: time.

They would choose a relatively safe time to send people out.

They will only send someone out if both conditions are met.

Regardless of the reason, all Yu Dazhang and his group can do now is wait.

While the work of a criminal investigator may seem tense and exciting on the surface, often involving a battle of wits with criminal traffickers, it is actually tedious and boring most of the time.

This kind of stakeout is the norm for our work.

Time passed by, and three hours went by in the blink of an eye. By then, it was completely dark.

Yu Dazhang took out his phone and checked the time.

7:10 PM.

At this point, he was also getting anxious. Things could go wrong if he waited too long, and he couldn't keep dragging this on indefinitely.

If this goes on for too long, Zhang Sen will really be in danger.

Just as he was considering whether or not to make the arrest, the walkie-talkie suddenly rang.

"A van drove out of the yard; it looked to be about 4.2 meters long."

Upon hearing this, Yu Dazhang immediately picked up the walkie-talkie:
"Don't follow them immediately. Keep a certain distance and wait until they get into the zone before you start following them."

"I'm so lucky..." Yu Dazhang felt a surge of excitement.

If I hadn't kept my composure, all my previous efforts would have been wasted.

When Fang Peng explained it before, he had calculated that the cargo box of this vehicle was 4.2 meters long and 1.8 meters wide, which was just right for carrying six or seven people.

So he is now basically certain that the truck was used to transport people.

And the next stop is very likely to be an underground prison.

Fang Peng once said that when he was kidnapped, he only changed cars once, and later fell asleep because the journey was too long.

From this perspective, he was taken directly to his destination after leaving the transit station.

"Group Six will stay and continue to keep an eye on that farmhouse."

Yu Dazhang, holding the walkie-talkie, quickly gave the order:

"Local police arrived and immediately made the arrests."
