While Sun Jun and others were dealing with Wang Huifang's murder case, Lu Chuan's fingerprint identification analysis was still continuing.
Although the lines on the fingerprints are relatively clear due to blood stains, because the fragmentation is extremely serious, Lu Chuan is unable to conduct a complete analysis and can only use similar analysis methods to manually screen.
Refreshing the system page for the third time, this time was the third time Lu Chuan adjusted his fingerprint and conducted system analysis.
Fragmented fingerprints not only fail to provide continuous feature points, but are also very small in number, which adds a lot of difficulty to Lu Chuan's analysis.
In the end, the method Lu Chuan adopted was to segment the blood fingerprint into four different and relatively complete parts, and then conduct identification and analysis on each part.
To put it simply, through this segmentation method, a fingerprint that cannot be analyzed as a whole is divided into four relatively independent fingerprints for identification and analysis.
In this way, there are two problems. One is that the workload increases.
In the past, only one fingerprint had to be analyzed, but now four fingerprints were analyzed, and the workload was four times that of the original.
Another problem is that the accuracy of the analysis is reduced. The four parts of fingerprints are compared and analyzed in the system. If the fingerprints of the same person can be compared, it means that the comparison is successful.
It is obviously more difficult to get to this point.
What Lu Chuan is doing now is the third part of fingerprint comparison.
It is said to be a comparison, but it is actually a kind of verification, because the results of the comparison of the previous two parts of fingerprints are the same person.
What Lu Chuan is doing now is to use the previous comparison results to directly check the quarter fingerprints separated in advance.
With the foundation of the first two times, the third comparison was completed quickly.
"Wang Jian...Huangzhou...should be him."
What Lu Chuan got was just a fingerprint, and he didn't read the relevant file materials.
I don’t know what the connection is between the deaths of Wang Jian and Wu Qizhou.
I don’t even know that once the deaths of Wang Jian and Wu Qizhou are linked, the following case investigation is likely to enter a new stage.
The Liangzhou case will most likely be solved.
“Done!”
With the last quarter of the fingerprint comparison successful, Wang Jian's identity has been confirmed.
With the results, the appraisal report is relatively simple, just some textual things, plus the screenshots of the system analysis that Lu Chuan just made, and it's done.
Qin Yong's conference room has just finished listening to Zhang Chao's interrogation report. This backlog of cases four years ago is now fully understood.
Good news also came from the excavation site in Xigou Village. The murder weapon was found, and the entire evidence chain was completed, so there was no problem.
Leaning back on the chair, Qin Yong let out a long breath.
This case has been going on for four years. Qin Yong was the detachment leader at that time. The case was not solved after it came out, and the entire criminal investigation detachment's year-end bonus was lost.
Actually, in reality, no one as a police officer can't solve the case.
Some cases cannot be solved, and you just deduct all your wages.
After all, there are cases pending in the ministries and commissions that cannot be solved, and there are also wanted criminals hanging there that cannot be caught.
But Qin Yong has no choice. This is the rule above. If the case cannot be solved, especially the murder case that has become a backlog, all the advanced competitions for that year will be cancelled, and all bonuses at the end of the year will be deducted.
Of course, the above is not without humane measures. If the previous murder cases are later solved, they will also receive large rewards.
As long as we maintain this momentum, we should have a good harvest at the end of the year.
The detachment leader is also a human being and makes little more money than others.
If you don’t engage in crooked ways, you will earn two to three thousand yuan more per month than ordinary police officers, but you will bear heavier responsibilities. If a case is not solved, the maximum amount of money will be deducted.
Thinking of this, Qin Yong unconsciously thought of Lu Chuan.
In four years, the criminal investigation detachment’s backlog of cases from four years ago to now has been completely cleared. "Today I drink heavily to celebrate the victory, and I will never stop until my ambition is fulfilled. The future is long..."
Dong, dong, dong.
Qin Yong, who was happily humming a little tune, immediately sat upright, picked up a pen and paper and pretended to start reviewing documents.
“Come in.”
The voice was still majestic, and the detachment leader was very impressive.
“Captain Qin, it’s me.”
“It’s Xiao Lu, come on, sit down.”
Seeing that it was Lu Chuan who knocked on the door, Qin Yong immediately stood up from the table and poured tea for Lu Chuan himself.
No one else has received this kind of treatment.
Of course, there should really be no one left.
In Qin Yong's understanding, Lu Chuan is the God of Wealth of the Criminal Investigation Detachment. On the one hand, the donated funds of 100 million are still in the hands of tens of millions.
This part of the funds has improved not only the hardware facilities of the detachment, but the team members are now much more courageous when traveling on business.
Not to mention staying in a five-star hotel, at least not staying in a guest house.
On the other hand, the backlog of cases that Lu Chuan solved were all performance points.
Once the performance points for a backlog of murder cases are obtained, the criminal investigation detachment will be ranked high in the year-end performance of the Haizhou City Public Security Bureau.
The key to solving this year is not just a backlog of murder cases, but also the results achieved in the city bureau fingerprint battle and the provincial department fingerprint battle, plus some small cases and discovered murders.
These are performance bonus points, and performance bonus points represent money.
In recent years, the provincial department has become more and more strict in the detection of murder cases.
So a part of the performance was specially selected as murder reward performance.
If there is no murder case in a place, well, this part of the money will not move. If there is a murder case and the case is solved, the money will be rewarded to you. If there is a murder case and the case is solved, all the money will be deducted, not to mention the year-end bonus, and there will be no point.
Although it is only two to three thousand yuan, for the police, this money is a lot, which is equivalent to a month's salary.
And sometimes ministries and commissions also have special rewards for murder investigation, and this part also has one thousand or eight hundred per person.
So, there is a murder case. Although it is hard and even inhumane for everyone to stay up late and work overtime, if the case is really solved, the reward is indeed considerable.
Lu Chuan uses this money to refuel every month, which is enough.
"Thank you, Captain Qin."
Lu Chuan took the black tea made by Qin Yong with both hands, stood up and thanked him.
Qin Yong waved his hand: "Thanks to your footprint identification and analysis for Wang Huifang's case."
Delayed murders are extremely rare, and ordinary people have no chance to come into contact with them.
Zhang Chao is also a talent. He can figure out these things just by watching movies.
"Everything should be done."
Lu Chuan took out the fingerprint identification and analysis report at hand: "Team Qin, this is the fingerprint you asked me to identify this morning, and the results are out."
Um?
You actually... won the competition? !
Qin Yong did not tell Lu Chuan in detail about the specific circumstances of this case.
However, Cheng Zihao explained in detail that if the fingerprints were indeed matched, it would probably not involve a human life. (End of this chapter)
