Rebirth 2014: I, the King of Criminal Investigation

Chapter 591 Are the kidnappers colleagues?
Yu Dazhang also detected confidence in his voice.

Someone is directing him!

Compared to before, Qi Jiandong's mindset has completely changed.

Without suspicion or doubt, he was now convinced that Yu Dazhang on the other end of the phone was a policeman.

It seems that the person beside him is a meticulous person, at least that's the impression Qi Jiandong gets.

Otherwise, he wouldn't have suddenly become so confident; this confidence stemmed entirely from his trust in that person.

I really don't believe it... When it comes to playing mind games, Yu Dazhang has never been inferior to anyone.

He paused for only a second before angrily saying:

"Hey Qi, even if you want to protect your brother, at least give a reasonable explanation."

“Let me tell you, you can run away but you can’t hide. If you don’t pay back the money, I’ll ask your parents for it. If they don’t have it, I’ll tear down your house.”

In situations like this, explanations are just a cover-up.

So there's no need for any explanation at all; just start criticizing.

That's why you have people around you in the technical department.

If he were alone here, Yu Dazhang would have already started swearing.

He now imagines himself as someone who has been cheated out of money, furious and wanting to curse the other person to the bone.

"You've been to my house?" Qi Jiandong asked.

Yu Dazhang noticed that he said "my home".

Moreover, he spoke very fluently, which shows that Qi Jiandong regarded his parents' place as his own home.

Humans are strange like that. Even if they are not filial, they still instinctively want to protect their family when facing outsiders.

"Your father gave me your and your brother's phone numbers."

Seeing that Qi Jiandong's attitude had softened, Yu Dazhang pressed his advantage, saying:

“You two are worse than animals. Your father hates you so much that he says he would rather die than see you again.”

Then he changed the subject, saying impatiently:
"Forget it, I'm not interested in your family's business. You should contact your brother and have him return the money to me."

He tried to make sure every word he said revolved around their family, in order to attract their attention as much as possible.

For some reason, Yu Dazhang had a feeling that Qi Jiandong across from him seemed very interested in the situation at home.

Sure enough, when Qi Jiandong spoke again, his tone had changed:
"How is he feeling?"

Yu Dazhang naturally knew who "he" referred to.

However, he found the question a bit absurd; was it something a rebellious son should ask?

Having been away from home for almost three years, if I truly cared about my parents' health, I would have gone home long ago. Why would I be asking a stranger now?

"What a fart!"

Yu Dazhang has no choice but to continue acting now.
"Given your family's circumstances, I reckon your dad would have to kill the dog in the yard before he could have a meal."

“You two brothers are really no good. You cheat and swindle people outside, and you don’t even leave any money for the family. I can see your father’s face is sallow. He’s just barely getting by.”

After these words, the other side fell silent.

Yu Dazhang held the phone up to his eyes for a moment, and after confirming that the other end of the call hadn't hung up, he put it back to his ear.

At the same time, he turned to look at Qian Cheng and the others.

The officer operating the computer reached out his hand and waved it at him.

Five seconds left!

At that moment, Qi Jiandong's voice came through the phone again:

"I……"

Yu Dazhang gripped the phone tightly, listening intently. He knew that once the other person finished speaking, the time would be almost up.

But he only heard the word "I," and then...

"Beep beep beep~" A busy signal came through.

Yu Dazhang was so angry that he almost threw his phone on the ground.

They hung up again at the most crucial moment.

Moreover, this time Qi Jiandong didn't hang up the call, because he had already started speaking. Normally, when people speak, they habitually finish the entire sentence before taking the next step.

Therefore, it must have been someone next to Qi Jiandong who saw that the time was almost up and hurriedly snatched the phone away.

Yu Dazhang looked at the police officer operating the computer:

"Is enough data obtained?"

Yes, he still clung to his last glimmer of hope.

It was precisely because he lacked technical knowledge that he took a chance.

"Still no good." The officer shook his head.

"Still 27 seconds, just a little bit short."

“Two superpositions should be enough,” Yu Dazhang asked, unwilling to give up.

"The other party didn't change their phone number, and both calls were from the same number. Shouldn't it be possible to add them together?"

In his view, since data is collected with every call, the more calls a phone number makes, the more data will be collected.

"Do you think this is like doing addition in elementary school?"

Before the police officer could even speak, Qian Cheng objected:
"Location is based on real-time data updates. The current coordinates are recalculated with each location request, and the previous location result is not automatically carried over to the next request."

He rolled his eyes at Yu Dazhang:
"Don't talk nonsense if you don't understand."

"Spend more time reading books on this subject, and don't spend all your free time looking for your girlfriend. The worst thing a criminal investigator can do is think with their lower body."

That was really hurtful... If we weren't such good friends, Yu Dazhang would have snapped back.

After waiting in the technical department for a while, and seeing that Qi Jiandong didn't call again, Yu Dazhang thought for a moment and then called back.

Instead, I heard a shutdown prompt.

That's bad, both brothers' phones are switched off.

After leaving the technical department, Yu Dazhang returned to the First Brigade and sat down at his desk. He began to calmly consider what would happen next.

Their counter-surveillance capabilities are a bit too strong.

Only now did he realize that the person who used his brains wasn't necessarily highly intelligent, but rather had done similar work before.

Some things can't be figured out just by having a high IQ.

For example, the call duration required for location tracking.

An ordinary person would think that the location tracking time should take at least one minute, because that's how it's portrayed in movies and TV shows.

Only those who have worked in criminal investigations would know that the limit is 30 seconds.

and also……

The fact that they thought of hiding in an unfinished building shows that they are very familiar with police investigation methods and have some understanding of the city's surveillance network.

Ordinary people certainly wouldn't dare to play psychological warfare with the police.

The fact that they dared to do this shows that they were confident they could escape the pursuit, and this confidence most likely came from experience.

Did you run into a fellow professional?
This is the only explanation that makes the most sense.

Yu Dazhang turned to look out the window, his mind racing.

If it's someone from the same industry, then this kidnapping case is really going to be difficult to handle.

The plan devised by the other side was definitely aimed at the police.

If someone is familiar with all the police's tracking methods, is it possible for them to escape unscathed?
The answer is yes.

In fact, there are many people who cannot be found in China, but live extremely luxurious lives overseas.

Tomorrow is the last chance... Yu Dazhang had a premonition that the kidnappers were very likely to achieve their goal this time.

Just as he was considering how to break the deadlock, Lü Zhongxin called him.

"I found it."

As soon as the call connected, Lü Zhongxin hurriedly said:

“There really is a young man in this village who knows sheet metal work and painting. I asked his family, and they said he went out to work a month ago and hasn’t returned yet.”
