Chapter 18 A bottle of Luzhou Laojiao
Humanity and sophistication exist everywhere.
Although Liu Guodong has no real power and only manages three people in the current survey office, it is different if he also takes over the trace inspection at the same time.
There are several criminal investigation squadrons under the Haizhou City Criminal Investigation Detachment. It also has its own action team, and cases happen every day.
Except for a very few cases that can be caught at the scene, other cases require the use of spot inspection to fix evidence.
For example, the footprint analysis done by Lu Chuan earlier.
Compared to footprint analysis, fingerprint comparison is a more common method for solving crimes.
In the current survey office, Liu Guodong, Yang Sen and Lao Bai are all experts in this field.
Of course, the so-called experts here are limited to the Haizhou City Criminal Investigation Detachment.
Fingerprint comparison is actually a basic required course for any criminal police officer. Even the police officers at the police station can tell some tricks.
Some experienced auxiliary police officers can also do some work in this area.
But just like the flexible employment staff standing on the streets in alleys, compared to the service staff in luxury clubs, there is most likely a certain gap in terms of technical proficiency or hardware facilities.
Most criminal police can compare some relatively complete fingerprints.
But the actual situation is that many of the fingerprints collected at the crime scene are incomplete.
Or if the deformation is serious, this requires higher technical ability.
Lu Chuan once studied fingerprint comparison when he was at the Public Security University, but it was impossible for a teacher to teach dozens of students step by step.
So, even a top student like Lu Chuan, who graduated from the Public Security University, has to follow the seniors step by step and accumulate bit by bit when he gets to work in actual jobs.
There are many cases and few technical staff, so the current survey office has become a hotpot.
After all, no matter which squadron leader or leader of the action group, you have to ask Liu Guodong and the others.
The arson case in the southern suburbs that Operation Group Two is responsible for is one of the bigger cases in recent days.
However, it was only one of them. There were still two robberies where the fingerprints had not been successfully compared. Yang Sen and Lao Bai were applying eye drops.
The leader of the second group is Ren Qiang, who joined the police in the same year as Liu Guodong. Most of the people of their age are already young heads.
Absolutely the backbone of the criminal investigation detachment, Ren Qiang took out the cigarettes, distributed them to Liu Guodong and others, and lit them for Liu Guodong himself: "Just compare ten sets of fingerprints first. We have a clue for action first. "
After hearing this, Liu Guodong's expression changed. He puffed out a smoke ring from the cigarette in his mouth and said, "Team 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.”
In Lu Chuan's opinion, Liu Guodong's expression was a little exaggerated.
Yang Sen took eye drops out of habit, and it took him the whole morning to compare the two sets of fingerprints.
And all the comparisons failed, which is not to the point of overexerting the eyes.
But Lu Chuan obviously would not interrupt and poured a cup of tea for Ren Qiang: "Team leader Ren, drink tea."
For Lu Chuan, most people no longer look at the newcomers. It depends on him. The detection of several cases in the past few days has made Lu Chuan famous in the criminal investigation detachment.
"Thank you," Ren Qiang took the tea cup and rolled his eyes: "Old Liu, I know that you have few people and many things to do..."
Ren Qiang then looked at Lu Chuan: "Why don't you let Xiao Lu help with the comparison? "For a moment?"
Lu Chuan was surprised and waved his hand hurriedly: "I can't be the team leader."
"I still have some research on footprint analysis. I have studied fingerprint analysis." Collection, but in terms of comparison, it really doesn’t work.”
Although a man can’t say no, Lu Chuan thinks it’s better to be realistic.
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 City Public Security Bureau.
But fingerprint comparison...
With the little talk he learned in school, let alone comparing with Liu Guodong, a senior auxiliary police officer is probably better than him. "Okay, Lao Ren, I'm so busy right now. I've seen the fingerprints on your case."
Liu Guodong has actually seen the fingerprints on the arson case in the southern suburbs a long time ago: "A total of thirty-six sets of fingerprints were collected. Except for a few incomplete sets, the rest are basically fingerprints after burning."
He casually pulled out the fingerprint file next to him: "Old Ren, you are also an old criminal investigator. Take a look for yourself. Can this fingerprint still be called a fingerprint?"
"Don't say I can't compare it, you just gave it to me. Go to the provincial department and let the experts compare, the probability of success is not high."
The scattered fingerprint files fell into Lu Chuan's eyes.
A bunch of dark fingerprints, no, look at that, there are no traces of fingerprints anywhere.
This must be what happens after being burned by smoke and fire.
Ren Qiang smiled awkwardly. The fingerprints were collected by their second operation team. He knew what they looked like better than anyone.
"Old Liu, there is really no other way, so we just collected these fingerprints. We stayed up all day."
When it comes to collecting fingerprints, it is actually best to 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 inspections every day.
Unless there is a major case, such as a murder, Liu Guodong and others will not show up at all.
It’s not that I’m too arrogant, it’s just that I’m really busy.
Therefore, the scenes of some cases are investigated and evidence collected by members of the action team.
This is 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."
"One bottle of Luzhou Laojiao!"
"Old Ren, don't say one bottle, just ten bottles. If you can't handle it, you just can't handle it."
One bottle of Luzhou Laojiao won't work, Ren Qiang I know what Liu Guodong said should be true.
Sighing, Ren Qiang was about to get up and leave. As soon as he reached the door, he suddenly looked back at Lu Chuan: "Xiao Lu, did you just say that you have research on fingerprint collection?"
Ah. ?
Lu Chuan, who was about to go to the cafeteria to cook, was slightly startled. He had indeed said that just now.
But when Ren Qiang asked this, it was obvious that something was 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 on fingerprint collection, he still had to see Liu Guodong whether he could go.
“A bottle of Luzhou Laojiao and a trip to Xiaolu!”
Tsk tsk.
Smash it, smash it, Liu Guodong said at the corner of his mouth: "This is not a matter of whether Laojiao is not old."
"Xiao Lu has just arrived after all. He has some experience in footprint analysis, but in fingerprint analysis Inexperienced, if you want to 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. I couldn't understand the meaning of Liu Guodong's words. He patted his chest and looked upright: "Don't worry, it was picked. The credit is due to the current survey. It has nothing to do with you if it is not picked."
"The wine will be brought to you later!"
Liu Guodong nodded with satisfaction. To be able to do things, it must be Lao Ren.
