Additionally, collecting fingerprints from the handlebars wasn't easy, most police officers at the station lacked this skill.
Carefully removing the winter gloves, Lu Chuan collected the fingerprints from the handlebars.
Judging by the vehicle's parking position, it seems the bike hadn't been moved since that night.
If soone had ridden it during this ti, the fingerprints on the handlebars would likely have been covered.
If that were the case, the situation would be much more complicated to handle.
Fortunately, not many people ride electric bikes in the winter, and Lu Chuan quickly collected several fingerprints.
"Let's go back to the station."
Yang Lin nodded, realizing the difference between himself and the present Lu Chuan.
"Chuan, in college... did we learn this stuff?"
Yang Lin didn't have much impression of it.
Could it be that they didn't attend the sa university?
"Actually, the instructor ntioned it during lab classes, not in detail, but I learned most of it from the cri scene investigation veterans."
Yang Lin nodded thoughtfully.
Exactly, we didn't learn this in school...
In the station's office, Lu Chuan directly proceeded with fingerprint preprocessing.
This ti, Yang Lin watched Lu Chuan frantically tapping away on the keyboard, utterly astounded.
What Fourier transform, what image statistic changes, what noise reduction, what image sharpening, what fingerprint image layering.
He'd never even heard of these terms.
Beep!
For a moderately difficult fingerprint, Lu Chuan completed the preprocessing in less than half an hour, and the system ran for three minutes before successfully identifying and analyzing it.
"Wu Degui?"
The fingerprint matched a sample owner nad Wu Degui, from the provincial capital, with no fixed abode and unemployed. His fingerprints were collected at his provincial hotown at Taicang County Chengguan Road Police Station.
"Haha, now let's see where you can run off to!"
Yang Lin was quite excited and happy.
The station chief's electric bike being stolen was no small matter at the Huaguang Street Police Station.
Old Huang promised that anyone who could solve the case would get a day off!
Regarding Lu Chuan's role, Yang Lin felt it was his own contribution.
After all, without him, how could Lu Chuan, a leader at the Criminal Investigation Team's cri scene investigation office, go to the scene of an electric bike theft and personally collect fingerprints?
Lu Chuan twisted his slightly stiff neck with his cervical bones cracking audibly.
"What's next?"
Technical work was his forte, but solving cases on the ground wasn't.
Lu Chuan had no experience in handling the next steps after confirming the suspect's information in a theft case.
"The next steps are easy, just call the Chengguan Road Police Station and ask about the situation."
"This guy is definitely a serial offender, so we should check whether he has accomplices in Haizhou City, and ask the local police station to understand the situation."
Strictly speaking, this kind of thing falls under the scope of cooperative investigation.
According to formal procedures, Huaguang Street Police Station would need to issue a cooperative investigation letter, report to the District County Public Security Bureau for approval, then send a correspondence to the Taicang County Public Security Bureau, and upon consent, proceed with the cooperative investigation.
But Yang Lin clearly didn't intend to follow formal procedures.
If we followed these procedures, it might take at least ten or fifteen days before getting any results.
By that ti, the suspect might have already left Haizhou City.
On the computer, Yang Lin directly used police instant ssaging to find the phone number for the Taicang County Chengguan Police Station.
Yang Lin looked at the number and directly dialed it.
"Hello, I'm from the Haizhou City Huaguang Street Police Station, there's this situation..."
Yang Lin briefly explained the situation: "This Wu Degui has seasoned theft skills, he must be a habitual offender... Yeah, you have records there? That's great!"
"Yes, yes, just the contact information is enough, with the contact information we can find him!... Great!"
Yang Lin wrote down a phone number on paper while talking.
After hanging up, he waved the note in his hand: "Done!"
Lu Chuan watched his old classmate contact the Chengguan Police Station throughout, suddenly feeling he didn't quite recognize him anymore.
Although they've been graduating for over half a year and often t, and frequently talked about work, it was quite different to directly observe.
In half a year, not only had he changed, but his classmate had as well.
They've transford from regular university graduates into competent police officers.
Lu Chuan had grown technically, while Yang Lin had grown in practice.
Everyone was progressing.
"Is having a phone enough?"
After organizing his thoughts, Lu Chuan pointed to the note in Yang Lin's hand.
Relying on phone tracking, current technology is mature, but resources aren't sothing a re police station can coordinate with.
So Yang Lin must have other ans.
"Having a phone is definitely enough, we're good at this!"
"Just watch ."
Clearing his throat, Yang Lin sat at his desk and dialed Wu Degui's cell number.
"Perhaps the southern sun shines on the northern wind"
"Perhaps ti gets blown away, disappearing without a trace"
…
"Perhaps on Xi'an's city walls, soone vows to never part"
"Perhaps only upon reaching Dali, love becos sincere"
Admittedly, Wu Degui's call ringtone was quite pleasant, after a few lyrics the call connected.
"Who are you?"
"Hello Mr. Wu, I'm a deliveryman from Shunfeng Express, you have a parcel from Chengguan Town, Taicang County, and due to our work mistake, the printed shipping address is blurry."
"We only have your contact number, would you like the parcel delivered to your current address, or returned to Taicang County for processing?"
"Parcel? From Taicang... What's in it..."
The caller mumbled: "Mr. Wu?"
"Ah..."
"How would you like the parcel handled?"
"Oh okay, have it sent to 78 North Station Road, just leave it at the Half Past Eight Supermarket."
"Alright Mr. Wu, wish you a pleasant day, we sincerely apologize once again for our mistake, goodbye!"
Click!
Upon hanging up, Yang Lin saw Lu Chuan with his mouth agape wide enough to fit an egg.
"Chuan?"
"You okay?"
"Okay?"
Lu Chuan swallowed, incredulous at his buddy: "Who taught you that?"
"Who needs to this taught?"
Yang Lin scoffed: "In our jurisdiction, online scams happen almost daily."
"There's the 'I'm Qin Shihuang, send money to restore the universe' type scams."
"There's remote work scams claiming you can make quick money."
"There's 'Grandpa's tea isn't selling, please buy so' scams."
"And express package lost, double compensation' scams."
Yang Lin, presumably thirsty, picked up his now cold tea and gulped down more than half a cup: "You thirsty?"
"No, no," Lu Chuan quickly shook his head.
"Just from hearing, how hard is it to con an address out?"
Watching the triumphant Yang Lin, Lu Chuan suddenly felt a sense of nostalgia.
Back when Yang Lin was dating, if he had this experience, how could Song Yaoyao have tricked him?
If they hadn't directly had a child, it would be doing a disservice to professional online scamrs.
