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

Chapter 187
Whether it's a forensic doctor in the province or a trace examiner, there are very few people who don't know Zhang Yuanchao.

As the No.1 forensic doctor in the province, Zhang Yuanchao has supported all the cases of the public security bureaus in the cities.

Those sitting here are all old criminal investigators, who have dealt with Zhang Yuanchao more than once.

"Hello, Mr. Zhang."

"Hello, Mr. Zhang."

Even Li Donglin, who had just left, came in again at this moment.

Although Zhang Yuanchao was very old, he was in good spirits, followed by Li Changgeng.

Lu Chuan might be the only one here who hasn't met Zhang Yuanchao himself.

But hearing everyone's address, and Li Changgeng behind the old man, of course he knew who it was.

"Mr. Zhang, hello!"

Lu Chuan stood up and saluted.

"Good, good, good looking talent!"

Zhang Yuanchao's voice was loud, and he looked at Lu Chuan with praise in his eyes: "I have read the two bone identification and analysis reports you made, which are very good, and some parts are more detailed than mine."

"Mr. Zhang is too much. When I was in school, the teacher taught me well."

Zhang Yuanchao shook his head, "I know all the professors of forensic medicine in the Public Security University. They are at most on the same level as me, but they can't teach students like you."

Lu Chuan didn't answer, how could he answer?
Besides, what he studied was surveying, not forensic medicine.

Among those professors of forensic medicine at the Public Security University, Lu Chuan had only attended public lectures.

"Are you interested in working in the provincial department?"

"Go to my studio, specializing in bone identification and analysis."

Uh……

Faced with Zhang Yuanchao's invitation, Lu Chuan was a little flattered.

"Thank you Mr. Zhang for your kindness. I haven't been working for a long time, and I want to practice at the grassroots level for a few more years."

Refused?
Lu Chuan actually refused? !

The other dozen or so experts looked at Lu Chuan as if they were looking at a fool.

Does he even know where the provincial office is?
How difficult is this place to get into?
Didn't see Sun Bing who graduated with a dignified doctorate, can he only do logistics support work?

The establishment of the provincial department is much smaller than that of the municipal bureau below.

In terms of the promotion mechanism, there is a meeting with the Municipal Bureau, but that requirement, there may not be a place in two or three years.

Zhang Yuanchao's studio was established with the approval of the Ministry and the only forensic science research laboratory in the province.

There is also the support of the Technical Appraisal Center below. Not to mention the work, the salary is good, and the special talent allowance is enjoyed.

Can directly settle in the provincial capital and obtain the official establishment of the provincial department.

What is compilation?

The end of the universe is the system.

Although everyone sitting here is an expert, none of them is qualified to enter the provincial office.

Zhang Yuanchao shook his head with some regret: "It's better to practice more at the grassroots level, so that you can come to me anytime you want to come in the future."

"Thank you, Mr. Zhang."

After sending Zhang Yuanchao away, Zhao Zhiguo stopped Lu Chuan: "Brother, don't you know how powerful Mr. Zhang's studio is?"

Lu Chuan shook his head, he really didn't know.

"Hey, you are still too young."

"Let me tell you, Mr. Zhang is not only the number one forensic doctor in our province, but also a special expert of the ministry, who enjoys state subsidies."

"His forensic science laboratory was specially approved by the ministry. Not only will he be staffed by the provincial department after he came in, but even if he goes to work in the ministry in the future, it is not impossible!"

"Why did you give up?"

Zhao Zhigao had a regretful expression, as if he had missed a 500 million lottery ticket.

Lu Chuan felt that it was indeed a pity.

"It's okay, Mr. Zhang said, I can come anytime I want in the future."

Zhao Zhigao's expression froze. He felt that Lu Chuan was pretending, but there seemed to be no evidence.

"I'm off to work."

Two groups of people came and went, and finally everyone could devote themselves to fingerprint identification and analysis.

The fingerprint identification analysis of the provincial department is not the same as that of the municipal bureau.

The fingerprint database is the province's backlog of cases, and all clues to solve the case point to fingerprints.

As for the types of accumulated cases, there are homicide cases, serious injury cases, health cases, robbery cases and so on.

The number of cases is very large, almost several hundred.

This number, in fact, only accounts for less than half of the more serious cases that have not been solved in the whole province.

After all, not all cases can be solved by fingerprints.

At many crime scenes, fingerprints were not collected.

As for the number of hundreds of cases, it is actually not many, after all, these are cases accumulated over the years.

Except for Lu Chuan, other experts have participated in the provincial and departmental fingerprint battle more than once.

Therefore, before the war, everyone will compare their previous cases, but no successful cases will be marked.

In this way, you can ensure that your comparisons are all new cases.

In this way, the probability of success is also higher than that of the comparison.

Lu Chuan did not have this benefit. It was his first time participating in the battle, and he had basically never seen any cases.

The reason why I say basically is because there were four murder cases in Haizhou City. Lu Chuan compared them, but failed. They should also be in the fingerprint database of the battle.

Turning on the system, Lu Chuan was still aiming at the backlog of homicide cases.

Anyway, no matter what the case is, the fingerprints are compared, and there is no case that has been solved so far. The difficulty of fingerprint comparison cannot be said, the case is small, the difficulty is small, and the case is large, the difficulty is great.

It's all about luck.

After a search, there are a total of 83 homicide cases.

This is the accumulation of all homicide cases in the province that can be solved by fingerprints in the past few decades.

Lu Chuan chose one at random and started fingerprint preprocessing.

This is a blood fingerprint, the clarity is acceptable, but the fingerprint is severely squeezed, and the middle part is all blurred.

It should be that the murderer used too much force to squeeze the fingerprints.

The processing of this kind of fingerprints is not easy, otherwise, it will not become a backlog.

Turn on the PS software, and Lu Chuan starts to transform the number of images.

As a result, the scene once staged at the Haizhou Public Security Bureau reappeared.

In the quiet conference room, there was the crisp sound of Lu Chuan typing on the keyboard quickly.

Many people looked up at the source of the sound.

Most fingerprint identification analysis requires a quiet environment.

Moreover, doesn't fingerprint identification rely on eyesight? When does it need to be the same as typing, relying on keyboard?
Sitting side by side, Zhao Zhigao and Lu Chuan heard the intensive sound of keyboards and leaned over to remind Lu Chuan to work first and play games.

A quiet environment is needed here.

"Lu Chuan, let's..."

As a result, after glancing at Lu Chuan's computer screen, Zhao Zhigao was stunned.

"Fuck... you... The Matrix?"

The data flow that fills the screen is like a waterfall.

Zhao Zhigao looked confused.

Isn't this person's method of identifying fingerprints different from that of us normal people?

Of course Zhao Zhigao doesn't know what Fourier transform is, let alone image layering.

He stood up and stood behind Lu Chuan, staring blankly at Lu Chuan typing on the keyboard.

Lu Chuan's mind was highly concentrated at the moment, and he didn't notice Zhao Zhigao.

At first glance, this fingerprint looks a bit bad, and it is difficult to identify and analyze it successfully with conventional methods.

However, after performing two-dimensional image number transformation and then completing preprocessing through Fourier transformation, the results obtained are very gratifying.

Lu Chuan is already restoring the underlying data, and it will be completed in two to three minutes.

As a result, Lu Chuan tapped the keyboard faster and louder.

After 2 minutes, the preprocessing of the fingerprint is completed.

Lu Chuan directly dragged it into the system for comparison.

3 minute later.

"Ding!"

A pleasant reminder sounded, and a "comparison successful" dialog box popped up on the screen.

Become!
