Lu Chuan resisted the current survey box and set off with Ren Qiang.

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

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

This is the experience of the old driver, where there are pits, where there are bags, the door is clear.

There was also a bottle of wine by the way.

Before leaving, Liu Guodong specially told Lu Chuan to come back early, and today the on-site investigation office will not work overtime and drink at night.

This was the first time Lu Chuan participated in the dinner party of the field survey office.

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

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

If you do what you do as a policeman, you may have a case at any time.

It's always bad to go to the scene drunk.

Criminals also don't pick the time to commit crimes.

Therefore, most of the time everyone at a dinner party is in moderation, except for a few people who are taken care of by everyone to drink more, others try to avoid affecting work.

What's more, the dinner party in the current survey office is not just Liu Guodong.

Over the years, there have been many people who have gone out of the current survey office.

Although not everyone is nostalgic, most of them know where their roots are.

And most of these people are now in management, although they are still the majority of blue shirts, but 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, Ren Qiang's car is much worse.

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

Friday, September 4th, fine.

Shilipo Village in the southern suburbs.

"The fire broke out in a 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 of gasoline at the scene, and after the analysis of the firefighters, it was determined that the suspect splashed the warehouse with gasoline and then caused the fire." ”

The most fundamental reason for arson cases is that once a fire is formed, it is extremely difficult to control it.

And it often causes mass casualties.

However, generally speaking, the proportion of accidental fires is relatively large, and the proportion of human arson is relatively low.

The scene of the fire was a mess.

From a rough point of view, the entire warehouse is more than 50 meters long, two-thirds of which has burned out, and the supporting steel frame of the color steel plate room has collapsed.

But a third of it didn't burn, and there were a lot of water stains 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 that have been burned, and assist the second operation team to solve the arson case in the southern suburbs."

Just survey the fire scene, extract two sets of fingerprints, and the task issued by the system is only the basic task.

After roughly observing the scene, Lu Chuan pointed to the collapsed part: "Team leader, where is the fire point?" ”

"Also, where were the fingerprints you collected?"

"There were two points of fire, one at the front gate of the warehouse and the other at the back."

"The fingerprints we collected were all on the periphery, and the fire scene was almost burned, and there was no way to collect fingerprints."

The places where fingerprints have been collected by the second action group have been marked, and the scene is still being protected, and the marking points are also there.

Not to mention anything else, at least the process work of the second group has done a good job.

Some details are very rigorous.

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

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

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

However, because of the fire, most of the things that 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 on-site survey office for comparison were all taken from the periphery of the warehouse.

And the fingerprints taken from these places, not to mention how likely it is that they belong to the murderer.

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

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

This warehouse is rented out to the outside world, and there is a profit of 30,000 yuan per year.

And the owner of the warehouse is a squad leader in Shilipo Village.

There are many people who are usually offended, and there are people who deliberately retaliate, and the possibility of arson is very high.

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

Lu Chuan first observed the fingerprints that had been collected by the second group of operations.

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

Generally speaking, there is basically no way to collect fingerprints that have already been collected for a second time.

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

In particular, fingerprints collected by non-professional criminal police officers.

How to say it, it's like a flower thief also has a rank, and some people not only steal people, but also steal hearts after picking.

Some people feel like they've eaten a piece of after picking it.

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

Most of them are violent shots, and they are basically fingerprints glued down with transparent glue.

No wonder the fingerprints are incomplete, if they are complete.

Giving up the devastated fingerprint scene, Lu Chuan could only find another way.

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

Recently, in addition to reading the novel "The Hundredth Blind Date, Arresting the Blind Date on the Spot", Lu Chuan was also obsessed with short videos.

I have to say, it's addictive to look at that thing.

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

Like collecting fingerprints, the device is right, and if you shake it twice, you can also have a fluctuation bombing.

If the equipment is wrong, you just shake the take-off, and the airport is still the airport.

Ren Qiang on the side was also a little confused.

When will the brushes used to collect fingerprints be LV?

Am I short-sighted?

"Xiao Lu, you are a brush......"

"You say this?"

Lu Chuan didn't hide it: "This brand of brush uses the hair under the armpit of the arctic fox, which is the softest and most resilient of all the brushes." ”

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

Ren Qiang nodded inexplicably, he hadn't seen what the arctic fox was, but he understood what the word tender meant.

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

is different from the roughness of the second action group, when Lu Chuan collects fingerprints, the technique looks like a girl caressing the soft skin, soft like a breeze.

Of course, in addition to the technique, there are some things that Ren Qiang can't understand.
