"Shen Yaowei has started a video call, do you want to see it?" Wang Chuanxing stepped forward and asked Jiang Yuan in a low voice.
"Shen Yaowei went with Group 6?" Jiang Yuan looked up.
"Yeah, they were really lucky." Wang Chuanxing was genuinely a little envious. Going to these eight locations with the team was partly to reduce the criminal investigation pressure on the Anwan City Public Security Bureau, and partly to claim credit.
This is essentially a joint mission between Shannan and Pingzhou. Pingzhou has its own reward system, and Shannan also has its own merit record. It would be a waste not to go.
However, only one person is likely to actually get a share of pork, and it's basically all down to luck. If Group 6 gets it, Shen Yaowei, who was in the group, will at least get a commendation, and if he can scrape together some more, a third-class merit is quite easy to achieve.
"Captain Jiang, we're now taking the suspect's fingerprints." Shen Yaowei, dressed in police uniform, saluted Jiang Yuan and switched the video feed to the front-facing camera.
A man with a clean, non-greasy face and bulging veins from tattoos on his arms was placed in the center of the video frame.
From a police officer's perspective, this person has a complicated past. Without a complex past, one couldn't have gotten such a large and beautiful tattoo, nor could one possess the composure to stand calmly even with ten police officers around their necks.
Two detectives flanked the suspect on either side, with the one on his right holding his hand and pressing his fingers against the palm print scanner.
Fingerprints are not only found on the front of the body, but also on the sides, which are often where fingerprints can easily be detected.
After pressing all ten fingers, the police officers at the scene pressed his palm prints and side palm prints. The principle was the same, but the area was much larger.
"Reporting to command, Group Six has completed fingerprinting." Shen Yaowei placed his phone on the table and respectfully saluted the camera.
The accompanying police officers all saluted. Everyone knew they were facing Jiang Yuan, and their expressions and movements were extremely serious.
The suspect, now handcuffed again, was somewhat dazed. His expression darkened, then changed completely, and he shouted, "Sir, I'm innocent! They violated my privacy, coerced me, and... they even hit my stomach..."
"Have the prosecutor intervene earlier. Send the documents." Jiang Yuan's two short sentences were also addressed to Shen Yaowei.
"Yes." Shen Yaowei quickly opened his laptop, connected the palm print scanner, and then packaged all the data inside...
The requirement of 1000 dpi is not low; at least for the current equipment and instruments in China, most cannot meet it. Shen Yaowei and his team specifically selected a newer model.
The suspect realized something was wrong and shouted again.
The police officer standing next to the phone during the video call quietly turned down the phone's volume.
Meanwhile, Jiang Yuan, thousands of miles away, had already had someone remove his phone. After Wang Chuanxing adjusted the format of the received file, Jiang Yuan directly opened the newly collected fingerprints and began comparing them one by one.
In theory, comparing such fingerprints doesn't even require marking feature points. Many veteran detectives in the past were skilled in this fingerprint comparison technique. When faced with a suspect, they would take out a pre-prepared fingerprint card, have the suspect press their fingerprint, and compare it on the spot. Why not use a mobile phone or laptop? Because they hadn't been invented yet.
The comparison work Jiang Yuan is doing now is essentially the same, except that he's using an additional high-definition system to see the third-level features of fingerprints, thus increasing the cost of fingerprint recognition from a one-cent fingerprint card to millions of dollars, and...
He was able to prove that the fingerprint belonged to this person using a smaller area of fingerprint.
Of the three levels of fingerprint characteristics, the most useful is the sweat pore feature. Every hole on everyone's body is different. For example, nostrils and eyes are unique; no one can have two identical nostrils and eyes.
Therefore, when a forensic technician obtains a fingerprint, if he can examine the sweat pore characteristics, he only needs a very small piece to serve as evidence.
Furthermore, and most importantly, sweat pores are arguably the largest of the three types of fingerprint features. Beyond that, features such as the width of the ridges and the edge shape of the papillary ridges require much greater magnification to be clearly displayed.
In other words, 1000 dpi is not enough, so 1500 or even 2000 is needed, otherwise the error rate will be too high—especially for a country like the United States. If a project has a high passive error rate, then there will definitely be people, including those inside and outside the law enforcement system, who will try to create a high active error rate by deceiving the public, in order to achieve their ulterior motives.
"Confirmed to be the same".
Just as everyone held their breath, Jiang Yuan completed the comparison.
The fingerprints collected from the clothing were discontinuous residual fingerprints, which greatly damaged the secondary features of the fingerprints, but did not affect the tertiary features. Although Jiang Yuan only spent a short time, he actually selected several locations and verified them multiple times before confirming the fingerprints.
After all, once he confirms this, the suspect on the other side should be arrested; making a mistake would be a real hassle.
Liu Zhuangshi, the detachment leader who had been waiting nearby, immediately picked up his phone and called the sixth team at the front line.
Shen Yaowei was just there to help out; the team leader was naturally from the Anwan Criminal Police Detachment.
Wang Chuanxing picked up his phone again, turned up the volume, and showed it to Jiang Yuan and the others.
The suspect's screams could be heard again during the ongoing video call.
He was aware that he was about to face punishment, especially after his initial wishful thinking was proven impossible. In the moment when all the worst prophecies were about to come true, the only thing he could rely on was power!
"what……"
On the screen, the suspect strained his arms, veins bulging, and even his tattoos seemed to be trying to become three-dimensional.
If this were the opening scene of a movie, he might actually have a sliver of a chance, but in today's scenario, the Chinese police officer was only worried that he would hurt himself, so he hurriedly reassured him: "Don't get agitated, it's alright. Once we figure out the situation, you can go back first..."
While they were deceiving him, the police officers on both sides extended their stun batons.
As the stun gun approached, Shen Yaowei couldn't help but add his own sound effects: "Sizzle..."
The suspect straightened his back, puffed out his chest, and stretched his neck, shaking from bottom to top like a mantis shrimp.
Then, the room fell silent.
The suspect stopped shouting, so the police officers who were trying to persuade him no longer needed to lie.
"We've taken the suspect back." The lead detective reported to Liu Zhuangshi, and after receiving permission, he escorted the suspect out the door.
In the conference room of the battle, Liu Zhuangshi's eyes were still shining brightly when he put down his phone, just like his five-year-old daughter asking for a toy. He stretched out his hands to Jiang Yuan: "Director Jiang, we still have a lot of evidence with fingerprints!"
