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

Chapter 19 Excessive Fingerprints
Lu Chuan went to the inspection box, followed Ren Qiang and set off.

As for the lunch, the second group of action will solve it, and the standard must be higher than that of the cafeteria, otherwise who will follow them to work overtime next time.

As for Liu Guodong's protection of Lu Chuan, Lu Chuan knew it well.

This is the experience of the old driver, where there is a pit, where there is a bag, the door is clear.

And a bottle of wine, by the way.

Before leaving, Liu Guodong specially told Lu Chuan to come back early. Today, the survey office will not work overtime and drink at night.

This is the first time that Lu Chuan participated in the dinner party of the survey office.

From the perspective of workplace survival, Lu Chuan has gradually integrated into the small group of the current survey office.

Of course, Liu Guodong and others don't drink often.

If you are a police officer, there may be a case at any time.

It's never good to go to a scene drunk.

Criminals don't take their time to commit crimes either.

Therefore, most of the time when we have dinner together, enough is enough. Except for a few people who are cared for by everyone, drink more, and others try to avoid affecting their work.

What's more, it's not just Liu Guodong and the others who are having dinner in Kan's office.

Over the years, quite a few people have left the survey office.

While not everyone is nostalgic, most know where their roots lie.

And most of these people are now in the management team. Although most of them are still in blue shirts, they are definitely important figures in various fields of the Haizhou Public Security Bureau.

Liu Guodong called Lu Chuan for dinner this time, just to introduce Lu Chuan to his seniors.

Compared with Qin Yong's car, Ren Qiang's car is much worse.

Compared with the [-]-year Cruiser, it is not a star and a half, but fortunately, it can shelter from wind and rain.

Friday, September [-]th, sunny.

Shilipo Village in the southern suburbs.

"The fire broke out in the rented warehouse of a farmer in Shilipo Village, which stored a lot of foreign trade clothes, and the loss was nearly one million."

After getting out of the car, Ren Qiang introduced the general situation of the arson case to Lu Chuan: "We found a bottle containing gasoline at the scene. After analysis by firefighters, it was determined that the suspect spilled gasoline into the warehouse and caused the fire."

The most fundamental reason for arson as one of the eight major categories of cases is that once a fire is formed, it is extremely difficult to control.

And often cause mass casualties.

But generally speaking, the proportion of accidental fires is relatively large, and arson is relatively low in the proportion of fires.

The scene of the fire was a mess.

At a glance, the entire warehouse is more than [-] meters long, two-thirds of which have been burned out, and the supporting steel frame of the color steel room has collapsed.

But there is still a third that has not burned, and there are many water spots on it.

It should be the reason for the timely fire rescue.

"Ding!"

"Basic task: Investigate the fire scene of the arson case in the southern suburbs, extract at least two sets of fingerprints, and assist the second group of operations to detect the arson case in the southern suburbs."

Just surveying the fire scene and extracting two sets of fingerprints, the tasks issued by the system are only basic tasks.

After roughly observing the scene, Lu Chuan pointed to the collapsed part: "Team Leader Ren, where is the fire?"

"Also, where were the fingerprints you collected?"

"There are two fire points, one is at the main entrance of the warehouse, and the other is at the back."

"The fingerprints we collect are all on the periphery. The fire scene has been almost burned, and there is no way to collect fingerprints at all."

The places where the second group of operations have already collected fingerprints have been marked, and the site is still under protection, and the marked points are also there.

Among other things, at least the second group did a good job in the procedural work.

Some details are very rigorous.

Lu Chuan nodded, looked around, and walked around the warehouse.

It seems that the murderer did not prevent the fire outside the warehouse in order to make the fire burn more thoroughly.

Instead, they pried open the door of the warehouse, then went inside and set fire to it.

However, because of the fire, almost all the things the murderer touched were burned, so the second operation team did not extract fingerprints from the ruins in the warehouse.

The fingerprints handed over to the survey office for comparison were all taken outside the warehouse.

As for the fingerprints extracted from these places, let alone the possibility of belonging to the murderer.

Even the clarity of the fingerprints, in Liu Guodong's eyes, could not be compared at all.

As for why he insisted on comparing fingerprints, it was because Ren Qiang suspected that the other party was a villager from Shilipo Village.

This warehouse is rented out, with a profit of 3 yuan per year.

The owner of the warehouse is a small captain of Shilipo Village.

Usually offended many people, some people deliberately retaliate, the possibility of arson is very high.

Ren Qiang and others have collected the fingerprints of all the villagers. As long as they can be compared successfully, there is a high probability that the case will be solved.

Lu Chuan first observed the fingerprints collected by the second action group.

The process of fingerprint collection is actually a kind of destruction of fingerprints.

Generally speaking, there is basically no way to carry out secondary collection of fingerprints that have already been collected.

Even if Lu Chuan has intermediate fingerprint collection skills, what he can do in this area is very limited.

Especially the fingerprints collected by non-professional criminal police.

How should I put it, it's like picking flower thieves also have ranks, some people not only steal people, but also steal their hearts after picking flowers.

Some people feel like eating a pile of shit after picking it.

The appearance of the fingerprint collection scene shows that the people in the second operation group have average skills and are too heavy handed.

Most of them were violent shots, basically fingerprints glued down with transparent glue.

No wonder the fingerprints are incomplete, it would be strange if they were complete.

Abandoning the devastated and disfigured fingerprint scene, Lu Chuan had to find another way.

Opening the survey box, Lu Chuan took out his own fingerprint collection equipment.

Recently, besides reading the novel "The [-]th Blind Date, Arresting the Blind Date Partner on the Spot", Lu Chuan has also become obsessed with short videos.

I have to say, watching that stuff is addictive.

There is a skill called wave shaking, which is an artistic expression that requires extremely high equipment.

Just like collecting fingerprints, if the device is right, just shake it twice, and there will be wave bombing.

If the equipment is wrong, you just take off in a wobble, and the airport is still an airport.

Ren Qiang on the side looked a little confused.

When will the brushes used to collect fingerprints be LV?

Is my experience short?
"Little Lu, you are a brush..."

"You said this?"

Lu Chuan didn't hide his secrets: "This brand of brush uses the underarm hair of the arctic fox, which is the softest and most resilient among all the brushes."

"Not only is it comfortable to use on the face, but also the least destructive to fingerprints when collecting fingerprints, especially suitable for collecting fingerprints in fragile environments such as fire scenes."

Ren Qiang nodded in confusion. He had never seen an arctic fox before, but he understood what the word soft meant.

Watching Lu Chuan collect fingerprints, there is a feeling of enjoyment.

Different from the roughness of the second group of operations, when Lu Chuan collected fingerprints, the technique looked like a girl touching the tender skin, and it was as gentle as a breeze blowing on the face.

Of course, apart from the technique, there are some things that Ren Qiang can't understand.
