Whether it's a forensic doctor or a trace examiner in the province, there are very few people who don't know Zhang Yuanchao.
As the number one forensic doctor in the province, Zhang Yuanchao has supported cases in all prefecture and city public security bureaus.
The people sitting here are all old criminal investigators and have dealt with Zhang Yuanchao more than once.
"Hello, Mr. Zhang."
"Hello, Mr. Zhang."
Li Donglin, who had just left, also came in again at this moment.
Although Zhang Yuanchao is very old, he is in good spirits, followed by Li Changgeng.
Lu Chuan may be the only person sitting here who has never met Zhang Yuanchao in person.
But after hearing everyone's names and Li Changgeng behind the old man, of course he knew who was coming.
"Hello, Mr. Zhang!"
Lu Chuan stood up and saluted.
"Okay, okay, what a talent!"
Zhang Yuanchao's voice was loud and he looked at Lu Chuan with praise in his eyes: "I have read the two skeleton identification and analysis reports you made. They are very good. Some parts are more detailed than mine."
"Thank you, Mr. Zhang. When I was in school, my teacher taught me well."
Zhang Yuanchao shook his head: "I know all the forensic professors at the Public Security University. At most, they are at the same level as me, but they cannot teach students like you."
Lu Chuan didn't answer. How could he answer this?
Besides, he studied forensic investigation, not forensic medicine.
Of the forensic science professors at the Public Security University, Lu Chuan had only attended public lectures.
"Are you interested in working in the provincial department?"
"Come to my studio, specializing in skeletal identification and analysis."
Well……
Facing Zhang Yuanchao's invitation, Lu Chuan was a little flattered.
"Thank you Mr. Zhang for your kindness. I have just started working and want to train at the grassroots level for a few more years."
Refused?
Lu Chuan actually refused? !
A dozen other experts looked at Lu Chuan like a fool.
Does he know where the provincial department is?
How difficult is it to get into this place?
Didn't I see that Sun Bing, who graduated with a doctorate degree, could 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 requirement for the city bureau, but for that requirement, there may not be a quota for two or three years.
Zhang Yuanchao's studio is the only forensic science research laboratory in the province approved by the ministry.
There is also support from the Technical Appraisal Center, not to mention not much work, good remuneration, and special talent allowances.
Can directly settle in the provincial capital and obtain official establishment from the provincial department.
What is preparation?
The end of the universe is the establishment.
Although everyone sitting here is an expert, none of them is qualified to enter the provincial department.
Zhang Yuanchao shook his head regretfully: "It's better to train more at the grassroots level, so that if you want to come here in the future, you can come to me at any time."
"Thank you, Mr. Zhang."
After sending Zhang Yuanchao away, Zhao Zhiguo pulled Lu Chuan back: "Brother, don't you know how awesome 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, he is also a special expert of the ministry and enjoys national subsidies."
"His forensic science laboratory was specially approved by the ministry. Not only will it be established by the provincial department after entering, but it will not be impossible to work in the ministry in the future!"
"Why did you give up?"
Zhao Zhigao's expression of regret was as if he had missed a five million lottery ticket.
Lu Chuan felt that it was indeed a pity when he looked at it.
"It's okay. Didn't Mr. Zhang say that if I want to come in the future, I can come anytime."
Zhao Zhigao's expression froze. He felt that Lu Chuan was showing off, but there seemed to be no evidence.
"I'm going to work."
Two waves
People come and go, and everyone can finally devote themselves to fingerprint identification analysis.
The fingerprint identification analysis of the provincial department is different from that of the municipal bureau.
The fingerprint database contains a backlog of cases across the province, and all clues to solving the case point to fingerprints.
As for the types of backlogged cases, there are homicide cases, serious assault cases, rape cases, robbery cases, etc.
There are many cases, almost hundreds.
This number actually accounts for less than half of the more serious cases that have not been solved in the province.
After all, not all cases can be solved relying on fingerprints.
At many crime scenes, fingerprints are not collected.
As for the number of hundreds of cases, they are 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 battles more than once.
Therefore, before the war begins, everyone will mark the cases that they have compared before but failed.
In this case, you can ensure that all the cases you compare are new.
This way the probability of successful comparison is higher.
Lu Chuan does not have this benefit. It is his first time to participate in the battle and he has basically never seen all the cases.
The reason why I say basically is because there were four murder cases in Haizhou City. Lu Chuan had compared them but failed, and they should also be in the battle fingerprint database.
Turning on the system, Lu Chuan was still targeting the backlog of murder cases.
Anyway, no matter what the case is, fingerprints are compared, and there is no case that has been solved so far. The difficulty of fingerprint comparison cannot be said. If the case is small, the difficulty will be small, and if the case is large, the difficulty will be greater.
It's all about luck.
A search revealed a total of eighty-three murder cases.
This is the backlog of all murder cases in the province that can be solved by fingerprints in the past few decades.
Lu Chuan randomly selected one and started fingerprint preprocessing.
This is a blood fingerprint, the clarity is acceptable, but the fingerprint is severely squeezed and the middle part is blurry.
It should be that the murderer used too much force, causing the fingerprints to be squeezed.
This kind of fingerprint processing is not easy, otherwise it would not become a backlog.
Opening the PS software, Lu Chuan began to convert the image numbers.
As a result, a scene that once took place at the Haizhou City Public Security Bureau reappeared.
The quiet conference room was filled with the crisp sound of Lu Chuan rapidly typing on the keyboard.
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 sight? When does it need to rely on typing on the keyboard like typing?
Zhao Zhigao and Lu Chuan were sitting side by side. Hearing the intensive sound of keyboards, they leaned over and wanted to remind Lu Chuan to work first and play games.
A quiet environment is needed here.
"Lu Chuan, let's..."
As a result, Zhao Zhigao was stunned when he glanced at Lu Chuan's computer screen.
"I guess...you are...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 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 at Lu Chuan as he typed on the keyboard.
Lu Chuan was highly concentrated at the moment and did not notice Zhao Zhigao.
This fingerprint looks a bit bad at first glance, and it is difficult to successfully identify and analyze it using conventional methods.
However, after performing two-dimensional image transformation and then completing preprocessing through Fourier transform, the results obtained are very gratifying.
Lu Chuan is already restoring the underlying data, and it will be completed in two or three minutes.
As a result, Lu Chuan tapped the keyboard faster and louder.
After two minutes, the fingerprint preprocessing is completed.
Lu Chuan directly dragged it into the system for comparison.
Three minutes later.
"Ding!"
A surprise prompt sounded, and a "Comparison Successful" dialog box popped up on the screen.
Done!
