Sit up straight, eyes level, and with Xiao Wang next to him, Jiang Yuan began to carefully mark the characteristic points of the fingerprints he had just received.

Xiao Wang looked even more serious.

In the grassroots police world, there is a saying that goes: police officers don't become criminal investigators, criminal investigators don't become technical criminal investigators, and technical criminal investigators refer to the forensic, on-site investigation, and drug testing personnel in the Criminal Investigation Department.

The reason for this is that those who become technical criminal investigators often have to act as ordinary criminal investigators. When they need to be at the scene, they need to be at the scene, when they need to run errands, they need to run errands, and when there aren't enough people to catch criminals, the technical police officers are the first to be caught.

Xiao Wang used to like to talk about this saying, but after Jiang Yuan arrived, Comrade Xiao Wang unexpectedly discovered a phenomenon.

Since Jiang Yuan started doing fingerprints, he has not been "caught" again.

The work of the criminal investigation team is never-ending, especially when there is a homicide case. The captain can stay awake for three days and nights with everyone, while ordinary police officers can take a nap and even laugh in their dreams.

But Jiang Yuan is always sitting in his office, like a rock. Even Xiao Wang, who is with him, has never been called away.

What surprised Xiao Wang even more was that no leader had ever ordered it, but whether it was within the Criminal Investigation Department or in other criminal investigation teams, even those who usually liked to take advantage of the situation had never called upon Jiang Yuan.

Actually, no one needs to say anything, Xiao Wang understands what's going on.

Because Jiang Yuan can directly lock in criminal suspects with fingerprints.

With this ability, which captain of which team wouldn't want to request him in the future? Even those who don't care about personal relationships would be reluctant to take Jiang Yuan away.

In the police force, there are places where rank is reflected, and places where age and seniority are reflected, but fundamentally, the work that everyone looks down on is the work that everyone cannot escape.

In summary, if you solve cases and I solve cases, who can be more noble than the other?

Naturally, those who can solve cases are more noble than those who cannot.

Xiao Wang wants to be a noble person.

Xiao Wang sat up straight, staring at Jiang Yuan's actions.

He watched Jiang Yuan mark the characteristic points and drew on his own leg, trying to understand Jiang Yuan's thought process.

Fingerprint comparison often depends on thought logic.

A break point may be a characteristic point, a noise point in the image, or an incomplete part of the fingerprint. Ultimately, how to judge it is a very difficult test of thinking.

Simple fingerprints don't matter how you do them, but when it comes to difficult fingerprints, you need to build up enough content in your mind first."Let's take a look." Just as Xiao Wang's mind was racing, Jiang Yuan finished marking and threw it to the software for matching. He only said it because he saw Xiao Wang looking at it.

Xiao Wang couldn't help but ask, "Are you done marking?"

"Yeah, I marked over ten, it should be enough."

"This is much easier than the arson case." Xiao Wang casually commented. From his perspective, both the fingerprints today and the arson case were extremely difficult. From a learning perspective, Xiao Wang was planning to learn with Jiang Yuan for another week.

However, Jiang Yuan only took less than half an hour to complete the first round of marking.

At this time, Jiang Yuan laughed, "Of course, the fingerprints from the arson case may be difficult to see due to burning. The extraction may not be very good."

The latter sentence was his true complaint. The conditions of the county bureau were not good, not just in one area, but in all areas.

The unit's computer made a squeaking sound.

Xiao Wang's attention was not here. He recalled the details of the feature points that Jiang Yuan marked earlier and felt like his mind was a mess, as if he had just taken a math test and had finished all the multiple-choice questions, but couldn't remember his answers when checking with his classmates.

Jiang Yuan checked the fingerprints one by one according to the list provided by the software.

Xiao Wang sorted out his emotions and followed Jiang Yuan's pace, slowly looking down.

He hadn't even looked halfway when Jiang Yuan swiped and changed to another fingerprint.

Obviously, the previous fingerprint had been excluded.

Xiao Wang frowned and followed Jiang Yuan to look at the second fingerprint.

It stopped before it was even halfway.

Continued, then stopped again.

Xiao Wang rubbed his eyes, feeling tired and exhausted.

This feeling was like when he was in school, listening to the teacher talk about the test paper, being very serious and attentive, but halfway through, the teacher said, "The rest is very simple, I won't talk about it anymore"...

Xiao Wang raised his head again, with a firm gaze and a strong expression - as an adult and a proud police officer, Xiao Wang felt that he had become extremely powerful!

"Matched." Jiang Yuan rechecked the sixth fingerprint and couldn't help but pat the table, standing up and stretching.

Xiao Wang's mouth couldn't help but curl up into a smile, slowly blooming, "We matched... that's great."

Jiang Yuan breathed a sigh of relief.

Fortunately, the person who left the fingerprint was a repeat offender. Otherwise, with only this one clue, it would be really difficult to identify the suspect."Cai Bin... This person has been arrested three times for stealing electric bikes," Jiang Yuan glanced at the record and was quite surprised, "He has been caught three times, but still uses violent methods to unlock the bikes. There has been no improvement at all."

"After improving, will he upgrade to stealing motorcycles?" Wu Jun came over to take a look after hearing that the fingerprints matched, "Criminals like him tend to escalate their crimes and lean more towards gang crimes. Especially after serving time in prison, it's even easier for them to do so."

Jiang Yuan recalled the videos he had watched and said, "He doesn't seem like a gang criminal. He steals one bike and leaves each time, and the value of the stolen bike is not necessarily high. He also doesn't have any accomplices..."

"Maybe no gang wants him," Wu Jun calmly interrupted Jiang Yuan.

Xiao Wang looked sympathetically at the computer screen with the suspect's photo and slowly said, "If it weren't for Jiang Yuan, no one would have caught him. The case value is too low and there are few clues."

Jiang Yuan took it as a compliment and hung up the phone to call Wei Zhenguo and Mu Zhiyang. The cigarette butt needed DNA testing, and he didn't know how long he would have to wait in line, so he would just catch whoever he could first.
