It's still a process of image layering and mathematical transformation.

Most of the fingerprints collected by Lu Chuan this time were blurred into paste, and the processing methods were relatively similar.

It's just that, compared with just now, the speed of computer computing this time is a little stuck.

Running the fingerprint comparison system and PS image processing software at the same time makes the computer a little overwhelmed.

In less than a minute, the roaring of the cooling fan rang out.

Lu Chuan didn't care, this is the normal working state of the computer.

Otherwise, what do you want to do with the cooling fan?

There is a voice, and only then can it be proved that the work is in place.

The buzzing roar continued, and so did Lu Chuan's identification and analysis.

Bite!

The fingerprint comparison system's unique sound of perfect match success is so pleasant.

Teacher Lu...... The comparison was successful......"

The prompt sound woke up Hu Xiaoyue, who had been watching from behind, but did not wake up Lu Chuan, who was processing fingerprints.

Hu Xiaoyue couldn't help but remind.

Lu Chuan turned his head blankly: "Are you ......?"

"Hello Mr. Lu, my name is Hu Xiaoyue, and I am a criminal police officer of the Investigation Office of the BZ City Criminal Investigation Detachment."

Hu Xiaoyue was generous, with two small dimples when she laughed, and raised her hands slightly, signaling the teacup in her hand.

"Just poured you tea...... But seeing that you are processing fingerprints, I don't dare to disturb you. ”

"Oh," Lu Chuan really didn't notice the policewoman: "I'm sorry, Officer Hu, I've been busy and didn't notice you." ”

"Also, you don't need to call me teacher, just call me Xiao Lu or Lu Chuan."

After saying hello, Lu Chuan had no desire to chat.

At this moment, the processing of the second fingerprint has reached a critical moment, and it is still a little bit more complete.

Hu Xiaoyue nodded lightly: "I just heard the system prompt, it should be that your fingerprint comparison was successful." ”

After reminding Lu Chuan, Hu Xiaoyue turned around and left, the tea in the teacup was cold and needed to be changed.

"Thank you."

After Lu Chuan thanked him, he turned his head and threw himself on the computer, continuing the final preprocessing operation of the second fingerprint.

The keyboard being tapped one after another, combined with the roar of the computer fan, actually has a symphonic feeling.

All members of the task force are busy.

This is a coordinated operation.

Dozens of people, including criminal investigation, economic investigation, and technical police, worked together to divide and cooperate.

However, a large number of people does not necessarily have an effect, just as the truth is often in the hands of a few.

Most of the time, the people involved in solving the crime just treat the job as a job.

Finding important clues sometimes requires a bit of luck, but most of the time it takes a little persistence.

0:28 a.m.

Bite!

The system sounded a pleasant prompt for the seventh time, marking the successful matching of fingerprints for the seventh time.

Of the thirteen fingerprints, Lu Chuan has successfully matched seven!

The report that just came out of the printer was still hot, and the information of the four people was displayed in front of Lu Chuan's eyes.

Thirteen fingerprints, two of which are Chen Gang's.

Apparently, in the basement, he left no less traces.

In addition to him, the information of three other people was compared, proving that they had been to this basement.

However, there were also six fingerprints that were not successfully compared.

"The target of these six fingerprints is not in the fingerprint bank."

Lu Chuan is very confident in the preprocessing of his fingerprints, and the blurring degree of the thirteen fingerprints is about the same.

The fingerprints obtained after the pretreatment are also about the same, and there is no reason why the seven are in the middle and the six are not in the middle.

The only possibility is that the owner of these six fingerprints did not enter fingerprint information in the fingerprint database.

But even then, seven fingerprints, locked four people are enough.

The results of DNA analysis have not yet come out, but Wang Hao and others are not too busy, and most of the samples cut out of the brick joints, sewers, and washbasins in the basement have been preprocessed.

Now it's time to wait for the results to come out of the instrument.

Inside the conference room.

Lu Chuan handed over the seven fingerprint identification analysis reports to Li Donglin.

At this moment, Li Donglin's eyes lit up like a wolf: "Okay! ”

"Very good!"

The fingerprints collected by Lu Chuan were seen by Li Donglin.

To be honest, he didn't have much hope for Lu Chuan.

Fingerprints that are blurry to the point where they can't see the lines clearly, even if he personally does the identification at his peak, there is no guarantee that it will be successful.

When Qin Yong of the Haizhou City Criminal Investigation Detachment recommended him, Li Donglin still had some concerns, thinking that he was the son of a high-ranking cadre.

If it weren't for reading Lu Chuan's information and knowing that he had performed well in several major cases, Li Donglin would not have agreed to Lu Chuan's entry into the task force so readily.

In hindsight, it was a wise decision.

Lu Chuan has such a high attainment in fingerprint identification.

It seems that the next time the provincial department organizes a fingerprint battle again, Lu Chuan will definitely show his skills.

"Check the information of these three people immediately!"

Among the four people who succeeded in Lu Chuan's comparison, one of them was Chen Gang.

He is now in shackles in the interrogation room.

Although this guy still hasn't said anything, he has Wang Manli's accusations and fingerprints as evidence, even if he doesn't say it, zero confession is enough to convict.

"Director Li, Wang Hao is still doing DNA analysis, and there should be results soon."

"I'll conduct a survey of Chen Gang's BMW early tomorrow morning."

Li Donglin nodded: "Chen Gang should have used that BMW car to transport Goldman Sachs from Haizhou City to BZ City." ”

"There should be some marks left in the car."

Lu Chuan nodded, he also meant the same.

In this way, the facts of Chen Gang's crime have been further confirmed.

In addition, Lu Chuan also sampled the imprints of vehicle tires.

It is necessary to compare it with the tire tracks collected by Lu Chuan on the ravine road in Xinjian Village last week, and after confirming the same, the evidence of Wang Manli's confession can be closed.

"Okay, have a good rest tonight, and do the survey after dawn tomorrow."

Li Donglin was originally a technical background, and he is very familiar with the work of on-site investigation and trace inspection.

Know how much work Lu Chuan has today.

In a basement of more than 100 square meters, it is enough to wipe the whole one.

What's more, a set of footprint analysis and the identification analysis of thirteen difficult fingerprints were also done.

Lu Chuan is young and has a good physical foundation, if he is replaced by him, he may not be able to survive.

After all, Li Donglin couldn't be clearer about how energy-consuming it is to do fingerprint identification and analysis.

Lu Chuan, who had nothing to say all night and slept beautifully in the guest house, was in good spirits the next day.

Chen Gang's BMW sedan had been towed from the villa to the criminal investigation detachment, right in the backyard.

After breakfast, Lu Chuan carried the survey box to the yard, preparing to conduct a survey of the imported BMW.

The first task is to extract the tire tracks of the vehicle.

Taking out the camera, Lu Chuan began to take pictures.

At the ravine site, Lu Chuan chose center photography and detailed photography among the four photo methods of orientation photography, overview photography, center photography and detail photography in the current survey photography.

This time, it's no exception.
