Chapter 187 Well-deserved reputation
Whether it’s a forensic doctor, a forensic examiner or a trace examiner, there are very few people in the province who don’t know Zhang Yuanchao.
As the number one forensic doctor in the province, Zhang Yuanchao has supported all cases of the prefectural and municipal 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 one 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.
"Good, good, 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. There are some places. It’s even more meticulous than what I did.”
“Mr. Zhang was praised for his good teaching when he was in school.”
Zhang Yuanchao shook his head: "I know all the forensic medicine 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 did not answer the question. How to pick up?
Besides, he studied field 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 and specialize in skeletal identification and analysis."
Uh...
Faced with Zhang Yuanchao's invitation, Lu Chuan was a little flattered.
"Thank you, Mr. Zhang, for your kindness. I have just started working for a short time and would like to train at the grassroots level for a few more years."
Rejected?
Lu Chuan actually refused? !
A dozen other experts looked at Lu Chuan like they were a fool.
Does he know where the provincial department is?
How difficult is it to get into this place?
I haven’t seen that Sun Bing, who has graduated with a doctorate, can only do logistics support work.
The establishment of the provincial department is much smaller than that of the municipal bureau below.
As for the promotion mechanism, there is a requirement for the Municipal 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 the support of the Technical Appraisal Center below. Not to mention not much work, the salary is not bad, and you enjoy special talent allowances.
Able to settle directly in the provincial capital and obtain official establishment from the provincial department.
What is preparation?
The end of the universe is the establishment.
It doesn’t matter that everyone sitting here is an expert, but none of them is qualified to enter the provincial department.
Zhang Yuanchao shook his head with some regret: "It's better to exercise more at the grassroots level, so that if you want to come in the future, you can come to me at any time."
"Thank you, Mr. Zhang."
< br>
After sending Zhang Yuanchao away, Zhao Zhiguo grabbed Lu Chuan: "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 is specially approved by the ministry. Not only will it be established by the provincial department after joining, it will not be impossible to work in the ministry in the future. ”
"Why did you give up?"
Zhao Zhigao's regretful expression was like missing out on a five million lottery ticket.
Looking at it, Lu Chuan felt that it was indeed a pity.
"It's okay. Didn't Mr. Zhang say that 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 going to work."
Two groups of people came and went, and everyone could finally devote themselves to fingerprint identification and analysis.
The fingerprint identification analysis of the provincial department is different from that of the municipal bureau.
The fingerprint database is a backlog of cases across the province, and all clues to solve the case point to fingerprints.
As for the types of backlogged cases, there are homicide cases, serious injury 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 by 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.
So, before the war begins, everyone will mark the cases that they have compared before but failed.
In this way, you can ensure that all the cases you compare are new.
The probability of successful comparison is also 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.
Opening 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 all depends on 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.
So, the scene that had been staged at the Haizhou City Public Security Bureau appeared again.
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.
Fingerprint identification analysis, most require 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.
"Oh... you... are 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 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.
But when performing two-dimensional image number 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 another two to three minutes.
As a result, Lu Chuan tapped the keyboard faster and louder.
Two minutes later, 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.
It’s done!
