Diary of a Criminal Investigator-Chapter 269: Democracy Road Police Station

"Seal off this luggage cart, no one is allowed to touch it!"

After arranging the follow-up, Liu Guodong and Lu Chuan left the hotel and returned to the Criminal Investigation Team.

"How is it going?"

In front of the computer, Liu Guodong was constantly watching Lu Chuan conducting fingerprint analysis.

The columns on the luggage cart were cylindrical, and the fingerprints Lu Chuan collected were irregular ovals.

Due to pressure, there was significant deformation.

Strictly speaking, conducting a fingerprint analysis on such fingerprints is quite challenging.

However, for Lu Chuan, who possesses advanced fingerprint analysis skills, it’s merely a matter of spending more time.

"Almost done!"

The speed of fingerprint preprocessing was fast; in less than twenty minutes, Lu Chuan had already completed the preprocessing of one fingerprint.

It has now been input into the system for comparison.

Lu Chuan didn’t randomly select the first fingerprint for analysis; it was specifically collected from a spot that Wang Laohu had gripped in the surveillance video.

Therefore, if this fingerprint matches, it can confirm Wang Laohu’s identity.

"Ding!"

Under the slightly tense watch of Lu Chuan and Liu Guodong, the system quickly displayed the comparison result.

"Match successful!"

"Ha!"

"Succeeded!"

Liu Guodong was so excited he almost jumped up; although he had confidence in Lu Chuan’s fingerprint analysis, he didn’t expect a successful match on the first try.

Lu Chuan was equally invigorated.

For a fingerprint analysis to be successful, two preconditions must be met.

One is that the fingerprint preprocessing must be flawless, and the other is that the fingerprint database must contain the target person’s fingerprints.

Open the target person’s information in the comparison system.

"Wang Guojun?"

As expected, Wang Laohu was not his real name; his real name is Wang Guojun.

"He has a criminal background in theft and robbery?"

"This guy is a habitual offender!"

There are roughly three sources of fingerprints in the fingerprint comparison system.

One is collected by the police station during tasks like identity card processing, public services, and other ways.

The second is from criminals with prior records, where all possible data, such as fingerprints, blood type, DNA, and footprints, are collected before imprisonment.

The third is fingerprints collected during case investigations, where they are systematically recorded after large-scale collection in major cases.

Besides these three, there are some other less common methods.

Wang Guojun’s is a typical example of previously recorded fingerprints.

"I’ll call Captain Qin; this guy isn’t getting away!"

Confirming the real identity makes it much easier to locate him.

Especially since Wang Guojun has a criminal record, he is a key surveillance target in the local police station.

Surely there are people in the system who know him.

The call connected quickly.

"Captain Qin, we’ve confirmed Wang Laohu’s real identity."

"Yes... his real name is Wang Guojun. We checked the system," Liu Guodong glanced at the household registration system Lu Chuan had opened.

"The registered address in the system is 28 Democracy Road... yes... Democracy Road Police Station, it’s Chen Feng’s area."

After hanging up, Qin Yong felt delighted.

He had been trying to figure out the kidnapper’s identity, not expecting that Crime Scene Investigation locked it down directly through fingerprints.

Speaking of which, this case...

The Crime Scene Investigation team has made quite an accomplishment.

The crucial video from the pinhole camera was discovered by them.

And through the surveillance video, they traced the whole kidnapping process and caught Song Hui, the insider.

Now, Lu Chuan has directly identified the kidnapper’s true identity through the fingerprints left by the kidnappers!

Good!

"Get Chen Feng, the police chief from Democracy Road Police Station, over here!"

Thirty minutes later.

"Captain Qin! Chen Feng from Democracy Road Police Station reporting!"

Chen Feng has been at Democracy Road Police Station since he started working.

Ten years ago, he became the deputy chief of the station, and three years ago, when the old chief retired, he became the chief.

In terms of career prospects for police officers, the chief of a police station is typically the highest position most can reach in their careers.

Even for a position like police chief, without notable achievements, one can only slowly work their way up to it.

Of course, some who have achieved first-class merit may have different career advancement opportunities.

Chen Feng is a representative of countless ordinary officers.

He has spent his life in law enforcement, never achieved any notable merits, won model worker awards several times, but otherwise lived a regular life.

Qin Yong greeted him back, "Old Chen, come take a look at this guy."

Qin Yong and Chen Feng have known each other for years, so their conversation lacks unnecessary formalities.

In Haizhou City Public Security Bureau’s subordinate police stations, except for a few, most chiefs are promoted locally.

Chen Feng, who has worked on Democracy Road for nearly thirty years, is very familiar with the area.

That familiarity is the main reason for promoting local chiefs.

As for the few police stations, they have some outsiders gaining experience and are usually supported by a local deputy chief, generally not causing any issues.

"Wang Guojun, also known as Wang Laohu, do you know him?"

"Wang Guojun?"

Chen Feng furrowed his brow and quickly responded, "Yes, he’s in our jurisdiction, has theft and robbery records, was released five years ago, and has a paralyzed mother at home."

Qin Yong wasn’t surprised by Chen Feng’s familiarity with Wang Guojun’s details.

Officers should know the individuals with criminal records in their jurisdiction well.

"We now have concrete evidence that Wang Guojun kidnapped Liu Bai from Haotai Hotel last night during a concert in Haizhou City."

"We are tracking his whereabouts, do you have any suggestions?"

"Kidnapping?"

Qin Yong nodded, "Yes, kidnapping for ransom, he called Liu Bai’s manager this morning demanding eighty million in cash."

"Eighty... million?"

"The demanded amount is enormous, and according to the insider at Haotai Hotel, they could kill anytime."

"While kidnapping Liu Bai, Wang Guojun had two accomplices, with one known as Third."

"Third... should be Wang Guojun’s cousin, committed crimes with him several years ago, also a habitual offender."

"Can you help locate them?"

"I’ll try when I return, but can’t guarantee anything."

"Alright, but time is of the essence; they gave us only three days."

"Understood!"

While Chen Feng took action, Ren Qiang and Sun Jun were also advancing the investigation.

They focused on the white Jinbei van used last night.

The traffic police gave full support, mobilizing all related road monitoring resources to trace the vehicle.

However, this tracking won’t yield immediate results.

The white van was recorded leaving Haotai Hotel and appearing on Friendship Road at the hotel’s entrance.

But not every intersection has monitoring.

The suspect might turn at any point between intersections.

This requires the police to check every piece of surveillance footage along the route.

Time flies by quickly in a day.
