Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 18 A Bottle of Luzhou Laojiao
Sophistication of the world exists everywhere.

Although Liu Guodong has no real power and only manages three people in the current survey office, it is different if the current survey also takes over the trace inspection.

There are several criminal investigation squadrons under the Haizhou Criminal Investigation Detachment, and it also has its own action team, and cases happen every day.

However, to solve the current cases, except for a very small number of cases that can be caught on the spot, other cases need to rely on spot inspection to fix the evidence.

For example, the footprint analysis that Lu Chuan did earlier.

Compared with footprint analysis, fingerprint comparison is a more common means of solving crimes.

In the survey office, Liu Guodong, Yang Sen and Lao Bai are all experts in this field.

Of course, the so-called expert here is limited to the scope of Haizhou Criminal Investigation Detachment.

Fingerprint comparison, in fact, is a basic compulsory course for any criminal policeman, and even the policemen at the police station can tell a little bit about it.

Some experienced auxiliary police officers can also do some work in this area.

But just like the flexible employees standing on the street in a small alley, compared with the service personnel in a luxury club, there is a high probability that there is a certain gap in terms of technical proficiency or hardware facilities.

Some fingerprints with relatively good integrity can be compared by the vast majority of criminal police.

But the reality is that many of the fingerprints collected at the crime scene are incomplete.

Or if the deformation is serious, this requires higher technical capabilities.

Lu Chuan once studied fingerprint comparison when he was in Public Security University, but it is impossible for a teacher to teach dozens of students hand in hand.

Therefore, even Lu Chuan, a high-achieving student who graduated from the Public Security University, has to follow the old predecessors step by step and accumulate bit by bit.

There are many cases and few technicians, so the current survey office has become a favorite.

After all, no matter which squadron leader, the leader of the action team, you have to ask Liu Guodong and the others.

The arson case in the southern suburbs that the second action group was in charge of was one of the bigger cases these days.

However, it was only one of them. There were two robberies whose fingerprints were not compared successfully. Yang Sen and Lao Bai were administering eye drops.

The leader of the second group is called Ren Qiang, who joined the police in the same year as Liu Guodong, and most people in their age group are already small leaders.

Definitely the backbone of the Criminal Investigation Detachment, Ren Qiang took out cigarettes, distributed them to Liu Guodong and others, and personally lit them for Liu Guodong: "Just compare ten sets of fingerprints first, and we have a clue of action first."

After Liu Guodong listened, his face changed, and he took half a puff of the cigarette in his mouth before blowing out a smoke ring: "Group leader Ren, do you know how long it takes to compare ten sets of fingerprints?"

"Look at Yang Sen and Lao Bai, they are almost blind."

From Lu Chuan's point of view, Liu Guodong's expression was somewhat exaggerated.

Yang Sen's eyedrops were also out of habit, and he only compared the two sets of fingerprints all morning.

Moreover, all the comparisons failed, so it was not enough to use the eyes too much.

But Lu Chuan obviously wouldn't interrupt, and poured Ren Qiang a cup of tea: "Leader Ren, drink tea."

For Lu Chuan, most people no longer look at him as a newcomer. The detection of several cases a few days ago has made Lu Chuan a lot more famous in the Criminal Investigation Detachment.

"Thank you," Ren Qiang took the teacup and rolled his eyes: "Old Liu, I know that you have fewer people and more things..."

Ren Qiang then looked at Lu Chuan: "How about asking Xiao Lu to compare?"

Lu Chuan was surprised, and hurriedly waved his hands: "Leader, I can't do it."

"I still have a little research on footprint analysis. In terms of fingerprint analysis, I have delved into fingerprint collection, but in terms of comparison, it really doesn't work."

Although men can't say no, Lu Chuan thinks it's better to seek truth from facts.

In terms of fingerprint collection, he has intermediate skills that are rewarded by the system, and he is confident that he can stand alone at the level of the Haizhou Public Security Bureau.

But fingerprint comparison...

As far as the little things he learned on paper in school, not to mention the comparison with Liu Guodong, a senior auxiliary policeman is probably better than him.

"Okay, old Ren, I'm so busy, I've seen the fingerprints of your case."

In fact, Liu Guodong has seen the fingerprints of the arson case in the southern suburbs: "A total of 36 sets of fingerprints were collected, except for a few incomplete sets, the rest are basically fingerprints after the fire."

He casually took out the fingerprint file beside him: "Old Ren, you are also an old criminal investigator, you can see for yourself, can this fingerprint still be called a fingerprint?"

"Don't say that I can't do the comparison. If you send it to the provincial department and let those experts compare it, the probability of being successful is not high."

The scattered fingerprint files fell into Lu Chuan's eyes.

A bunch of jet-black fingerprints, no, look at that, where there are no fingerprints.

This must be the case after the smoke and fire.

Ren Qiang smiled awkwardly. The fingerprints were collected by their second action team. He knew what it looked like better than anyone else.

"Old Liu, there is really no other way. We just collected these fingerprints. We all stayed up all day."

When it comes to collecting fingerprints, in fact, it is best to go to the people who do the survey.

But in fact, there are only four people in the current survey office, and they are too busy to sit at home and do trace inspection every day.

Unless there is a major case, such as a murder case, otherwise, Liu Guodong and others will not show up at all.

It's not that she's arrogant, it's that she's really busy.

Therefore, in some cases, people from the action team conduct investigations and collect evidence at the scene.

This was the case with the arson case in the southern suburbs.

"Old Liu, can you think of a way?"

"No way, these fingerprints are basically worthless for comparison."

"A bottle of Luzhou Laojiao!"

"Old Ren, don't say one bottle, it's ten bottles, if you can't handle it, you can't handle it."

A bottle of Luzhou Laojiao would not work, Ren Qiang knew that what Liu Guodong said should be true.

Sighing, Ren Qiang was about to get up and leave. Just as he walked to the door, he suddenly looked back at Lu Chuan: "Xiao Lu, you just said that you have research on fingerprint collection?"

what?
Lu Chuan, who was about to go to the cafeteria to make dinner, was slightly taken aback. He really said that just now.

But Ren Qiang asked this, obviously there is something wrong.

As a qualified professional, Lu Chuan set his sights on Liu Guodong.

Ren Qiang also knew what Lu Chuan meant. Although he had researched fingerprint collection, it was up to Liu Guodong whether he could go.

"One bottle of Luzhou Laojiao, Xiao Lu will make a trip!"

Gee.

Liu Guodong smashed the corner of his mouth: "This is not a matter of whether Laojiao is not Laojiao."

"Xiao Lu has just arrived after all, and has some experience in footprint analysis, but lacks experience in fingerprint analysis. If you collect..."

Liu Guodong glanced at Lu Chuan: "It's okay to try, but we can't guarantee that we will be able to collect clearer fingerprints."

Ren Qiang couldn't understand the meaning of Liu Guodong's words, and he patted his chest with a righteous face: "Don't worry, I got the pick, the credit is due to the current survey, and it has nothing to do with you if you don't get the pick."

"The wine will be delivered later!"

Liu Guodong nodded in satisfaction. If he wanted to be able to do things, he had to be Lao Ren.
