Gao Wenxiang was taken aback.
He wiped his mouth and glanced at the people around him who went out for a smoke, and the Deputy Director Wang Kai standing in the middle of the conference room.
What’s going on?
Didn’t we just have a couple of cigarettes? This doesn’t count as slacking off, does it?
Why is the director here?
"Director Wang..."
Wang Kai bypassed Gao Wenxiang and headed straight for Lu Chuan behind him, his eyes lighting up.
The fingerprint campaign, Haizhou City Public Security Bureau conducts it every year.
However, the results have always been unsatisfactory. In previous years, when Wang Kai was the team leader of the Criminal Investigation Team, there were occasional campaigns that ended with nothing to show.
A group of city bureau experts spent a week on the fingerprint campaign without a single result, a situation that was laughable.
So, later on, they ca up with a solution: the fingerprint campaign would include so less difficult cases.
This way, although breakthroughs in old cold cases were hard to co by, at least the data looked better.
The work report would at least have a few numbers to back it up.
Therefore, for this fingerprint campaign, Wang Kai didn’t hold any hopes.
But who would have thought, just two hours after the mobilization eting ended, shocking news ca from the campaign site.
"Lu Chuan, did you hit on the case from seven years ago?"
Wang Kai got the information imdiately, because during the fingerprint campaign, all results are reported imdiately.
Sun Hao completed the first fingerprint comparison, and the relevant information system sent the data to Wang Kai.
Of course, the fingerprint Sun Hao successfully matched was a small case deliberately included.
Just for the numbers.
However, fifteen minutes ago, another successful match information was automatically sent to Wang Kai’s phone by the system.
Seven years ago, a murder happened in the High-tech Zone of Haizhou City.
In the Culture Park, a woman working a night shift was killed in the early hours in the bushes.
A weapon was left on the scene, an ordinary stone.
Wang Kai rembered the case vividly, as it happened during his ti as the Criminal Investigation Team leader.
Later, even after his promotion, Wang Kai never let go of this case.
He organized annual case analysis sessions to review the clues discovered at that ti.
Unfortunately, when the case occurred, there were no surveillance caras at the scene, nor any eyewitnesses late at night.
The killer acted randomly, leaving behind nothing but a single distorted, twisted half fingerprint on the stone.
Wang Kai specifically requested the experts from the Provincial Hall to conduct identification analysis on this fingerprint.
Over several attempts, the fingerprint couldn’t be matched successfully.
Now, in the fingerprint campaign held by the Haizhou City Public Security Bureau, it was successfully matched!
Wang Kai headed to the campaign conference room imdiately.
The case from seven years ago?
Lu Chuan nodded: "You an the Culture Park case in the High-tech Zone? It’s matched?"
As soon as Wang Kai ntioned the case date, Lu Chuan knew it was the fingerprint he had just processed.
"I just went out for a cigarette, the system was running on its own."
While speaking, Lu Chuan moved to his computer, where the screen showed four crimson large characters.
Match successful!
Indeed!
"Director Wang, it really matched... the person is... a janitor... Li Zhi?"
Li Zhi?
Wang Kai leaned forward to the computer, watching the basic information of the fingerprint match target: "It’s him, indeed!"
"Lu Chuan, well done!"
"I’m arranging for the arrest now. The case is solved, and you’ll get first credit!"
Wang Kai walked off energetically.
The remaining seventeen or eighteen people stared at each other, Gao Wenxiang stamred: "Lu... brother... did you match a murder case?!"
The other detectives who had just t Lu Chuan also looked at him in astonishnt.
During the fingerprint campaign, matching a murder case ans at least a third-class rit for the detective if the person is captured and the case solved!
Everyone leaned in, eager to see the fingerprint identification analysis Lu Chuan had conducted.
The case from seven years ago in the Culture Park of the High-tech Zone was one everyone there knew about.
Especially Gao Wenxiang, as the case happened in their High-tech Zone.
He was involved in solving the case back then, and knew the condition of that fingerprint better than anyone.
It wasn’t matched even in the Provincial Hall’s fingerprint campaign.
Lu Chuan... managed to do it in two hours?
Sun Hao also leaned in.
Fingerprint identification analysis takes no shortcuts.
Matched is matched, unmatched is unmatched.
The murder case from seven years ago in the Culture Park, he was familiar with that fingerprint, having tried to study it multiple tis without any clues.
Lu Chuan, however, was unconcerned. With his advanced fingerprint identification analysis skills, as long as the fingerprint database contained the target’s fingerprints, failing the match would be a problem: "Luckier, perhaps."
It’s better not to be too high-profile, Lu Chuan greeted the officers he had just smoked with, indifferent to the crowd gathering behind him.
From the remaining twelve murder cases, he picked one at random.
Four years ago, a ho invasion robbery happened in the High-speed Rail New District.
The hoowner was silenced along with the others.
Based on the situation at the ti, it was basically determined that the perpetrator was a wanderer.
Outside the victim’s ho’s door fra, a bloody fingerprint was discovered.
Due to bloodstaining and friction marks, the fingerprint didn’t display the usual patterns.
Instead, it resembled a sar imprint.
This type of fingerprint is common at murder scenes, but also the hardest to identify and analyze.
Due to friction, the fingerprint was completely deford, with only the start and end of the fingerprint showing patterns, leaving no clues elsewhere.
Lu Chuan dragged the fingerprint into Snapseed image editing software, first processing the bloodstained edges.
Then he used his self-written software program to convert the image.
The crowd once again heard the clacking of keyboard keys.
Gao Wenxiang witnessed the data stream filling the screen like during a hacker attack once more.
The others behind Lu Chuan were awestruck.
Previously, during Lu Chuan’s first fingerprint handling, they just heard the keyboard clacks without seeing the data streaming like Gao Wenxiang did.
Is this fingerprint identification analysis?
The image-processing criminal police from the Criminal Investigation Team didn’t seem particularly impressive either?
Lu Chuan continued processing the fingerprint, and the number of people watching behind him grew.
More than a dozen people gradually gathered behind Lu Chuan.
Especially Sun Hao, who was practically leaning on Lu Chuan’s back, his eyes fixed on Lu Chuan’s operations.
Technically speaking, as a tech reconnaissance officer at the technical identification center, Sun Hao was more comprehensive than those in lower units.
But he knew he was just a notch above the others in terms of technical level.
When the city bureau organizes its fingerprint campaign, having any achievents is already the limit.
However, facing old murder cases...
If he had that skill, these cases wouldn’t be cold cases.
So, for Lu Chuan to match a murder case ant his skills exceeded everyone else’s by far.
Not learning from this would an letting himself down.
This ti, it took nearly another two hours.
More than a dozen people surrounded Lu Chuan, watching him mark the fingerprint’s characteristic points, process the data, and drag it into the system for matching.
Then, within a few minutes, the familiar yet sowhat unfamiliar notification sound rang out again!
