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

Chapter 102 Seven Fingerprints

It is still the process of image layering and mathematical transformation.

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

However, compared with just now, the speed of the computer calculation this time is a bit slow.

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 roar of the cooling fan sounded.

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

Otherwise, what do you need a cooling fan for?

Only when there is a voice can it prove that the work is in place.

The humming and roaring continued, as did Lu Chuan's identification and analysis.

Ding!
The sound of a perfect match unique to the fingerprint comparison system is so pleasant.

"Teacher Lu...the comparison was successful..."

The notification 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 reminding her.

Lu Chuan turned around in a daze: "You are..."

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

Hu Xiaoyue is graceful, she has two small dimples when she smiles, and raises her hands slightly to indicate the teacup in her hand.

"I just poured you tea... But I saw you were dealing with fingerprints, so I didn't dare to disturb you."

"Oh," Lu Chuan did not notice the female policewoman, "Sorry, Officer Hu, I have been busy and didn't notice you."

"Also, don't call me Teacher, just call me Xiao Lu or Lu Chuan."

After saying hello, Lu Chuan had no desire to continue the conversation.

At this moment, the processing of the second fingerprint has reached a critical moment, and it is almost finished.

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 and left. The tea in the teacup was cold and needed to be replaced.

"Thank you."

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

The keyboard was tapped one after another, combined with the roar of the computer fan, it felt like a symphony.

All members of the task force are busy.

This is a coordinated battle.

Dozens of criminal investigators, economic investigators, and technical police officers work 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 people.

For the most part, those involved in solving crimes just treat their jobs like jobs.

The discovery of important clues sometimes takes a little luck, but most of the time it takes a little persistence.

It was 28:[-] in the middle of the night.

Ding!
The system sounded a melodious prompt for the seventh time, marking the seventh complete fingerprint matching success.

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

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.

Thirteen fingerprints, two of which belonged to Chen Gang.

Obviously, in the basement, he left quite a few traces.

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

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

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

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

The fingerprints obtained after preprocessing are also similar. It is unreasonable that seven of them are compared and six are not.

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

However, even so, seven fingerprints are enough to lock four people.

The DNA analysis results have not yet come out, but Wang Hao and others are not too busy. Most of the test materials extracted from the brick cracks in the basement, the sewer, and the sink have completed pretreatment.

Waiting for the results now.

conference room.

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

At this moment, Li Donglin's eyes brightened like a wild wolf: "Okay!"

"very good!"

Li Donglin had seen the fingerprints collected by Lu Chuan.

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

The fingerprints were so blurred that the lines could not be seen clearly, even if he did the appraisal himself at his peak, there was no guarantee that it would be successful.

When Qin Yong of the Haizhou Criminal Investigation Detachment recommended him, Li Donglin was still a little apprehensive, thinking that he was a high-ranking son of some family.

If he hadn't roughly read Lu Chuan's information and knew that he had outstanding performance in several major cases, Li Donglin would not have agreed to Lu Chuan's entry into the task force so readily.

Looking at it now, it was a wise decision.

Lu Chuan has such a high attainment in fingerprint identification.

It seems that Lu Chuan will definitely show his skills next time the provincial government organizes another fingerprint battle.

"Check the information of these three people immediately!"

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

Now shackled in the interrogation room.

Although this guy still doesn't say anything until now, but with Wang Manli's accusation and fingerprints as evidence, even if he doesn't say anything, a zero confession is enough to convict him.

"Director Li, Director Wang Hao, they are still doing DNA analysis, and the results should be available soon."

"I will inspect Chen Gang's BMW early tomorrow morning."

Li Donglin nodded: "Chen Gang probably used that BMW 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 thing.

In this way, Chen Gang's criminal facts were further confirmed.

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

It needs to be compared with the tire marks collected by Lu Chuan on the Shangou Township Road in Xinjian Village last week. After confirming the same, the evidence closed loop can be closed for the situation Wang Manli explained.

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

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

I know how much Lu Chuan's workload is today.

For a basement of more than 100 square meters, it is tiring enough to wipe it all over.

What's more, a group of footprint analysis and identification analysis of [-] difficult fingerprints were also done.

Lu Chuan is young and has good health. If it were him, he might not be able to survive.

After all, Li Donglin knows all too well how exhausting it is to do fingerprint identification and analysis.

Having nothing to say all night, Lu Chuan, who had a good night's sleep in the guest house, was full of energy the next day.

Chen Gang's BMW car has been dragged from the villa to the Criminal Investigation Detachment, which is in the backyard.

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

The first job 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 central photography and detailed photography among the four photographing methods of azimuth photography, overview photography, central photography and detailed photography in the field survey photography.

This time, it is no exception.
