Gao Wenxiang was stunned. He touched his mouth and looked around at the people going out to smoke together, as well as Deputy Director Wang Kai standing in the middle of the conference room.
what's the situation? If a few of them just smoked two cigarettes, it wouldn't be considered fishing. Why is the director here?
"Wang Bureau..." Wang Kai passed Gao Wenxiang and went straight to Lu Chuan behind him, his eyes seemed to be shining. The Haizhou City Public Security Bureau conducts fingerprint battles every year.
However, the results have never been ideal. A few years ago, when Wang Kai was still the captain of the Criminal Investigation Detachment, he would occasionally shave his head during battles.
A group of experts from the sub-city bureau had no results at all in a week-long fingerprint battle, which would make people laugh if they told it.
Therefore, everyone later thought of a way to include some less difficult cases in the fingerprint battle.
In this case, although it is difficult to make breakthroughs in old cases, the data will at least look better.
There can be a few figures in the work report to support the scene. Therefore, Wang Kai had no illusions about this fingerprint battle.
But who would have thought that just two hours after the mobilization meeting, shocking news came from the battle site.
"Lu Chuan, did you win the case from seven years ago?" Wang Kai got the news immediately because during the fingerprint battle, all results were reported immediately.
When Sun Hao completed the first fingerprint comparison, the relevant information system was also sent to Wang Kai.
Of course, Sun Hao's successful fingerprint comparison was a small case deliberately put in. For recharging.
However, fifteen minutes ago, another winning message was automatically sent to Wang Kai's mobile phone by the system.
Seven years ago, a murder occurred in Haizhou High-tech Zone. In the Cultural Park, a woman was killed in the bushes after leaving the night shift in the early morning.
The murder weapon was left at the scene, an ordinary stone. Wang Kai was very impressed by the case at that time, which happened when he was the head of the criminal investigation detachment.
Later, although Wang Kai was promoted, he never let go of the case. An security case analysis is organized every year to sort out the clues discovered that year.
Unfortunately, when the crime occurred, there was no surveillance at the scene, and there were no witnesses late at night.
The murderer probably committed the crime randomly, and there were no clues except for a half-fingerprint that was twisted into a mess and collected on a stone.
As for this fingerprint, Wang Kai specially asked experts from the provincial department to conduct identification and analysis. As a result, the comparison was unsuccessful two or three times.
Now, in the fingerprint battle organized by the Haizhou City Public Security Bureau, it was successfully compared! Wang Kai came to the battle conference room immediately.
The case seven years ago? Lu Chuan nodded: "You mean the case in the Hi-tech Zone Cultural Park? Did you win?" As soon as Wang Kai told the time of the crime, Lu Chuan knew it was the fingerprint he had just processed.
"I just went out to smoke a cigarette, and the system was running on its own." As he spoke, Lu Chuan walked to his computer, and there were four big words in scarlet on the screen.
Comparison successful! really!
"Wang Ju, we did win...the opponent is...the cleaner...Li Zhi?" Li Zhi? Wang Kai leaned in front of the computer and looked at the basic information of the successful fingerprint comparison target: "It is indeed him!"
"Lu Chuan, well done!"
"I'm arranging the arrest now. The case is solved, and you will be credited with the first credit!" Wang Kaifeng left in a hurry. The remaining seventeen or eight people were staring with big eyes. Gao Wenxiang stammered: "Lu... brother... you have been involved in the murder case?!" Several other detectives who had just met Lu Chuan also looked at Lu Chuan in surprise.
During the fingerprint battle, if the murder case is compared, as long as the person is caught and the case is solved, the criminal police who compares the fingerprints will at least have a third-class merit!
Everyone came together in a hurry to look at the fingerprint identification analysis done by Lu Chuan. Everyone here is aware of the case of the High-tech Zone Cultural Park seven years ago.
Especially Gao Wenxiang, the case came from their high-tech zone. He had also participated in the detection of the case back then, so he knew better than anyone the moral character of the fingerprint involved in the case.
Those were the fingerprints that were not matched in the provincial fingerprint competition. Lu Chuan...can it be done in two hours?
Sun Hao also came over. There are no shortcuts in fingerprint identification analysis. If you hit, you hit, if you miss, you miss.
He was also familiar with the fingerprint from the murder case in the Hi-tech Zone Cultural Park seven years ago and had studied it more than once.
However, there is obviously no clue. Lu Chuan didn't care too much. With his advanced fingerprint identification and analysis capabilities, as long as there were fingerprints of the target person in the fingerprint library, there would be no problem if he failed to compare: "Better luck." You still can't be too high-profile. Lu Chuan and the few just mentioned The smoking policeman said hello and didn't care that everyone was crowding behind him.
Of the remaining twelve murders, one was selected at random. Four years ago, a home invasion and robbery occurred in the High-speed Railway New District.
The head of the household was also silenced. Based on the situation at the time, it was basically determined that the other party was on the run to commit the crime. A bloody fingerprint was found on the frame of the outside door of the deceased's home.
Because it was stained with blood and had traces of friction, the fingerprints did not show the usual pattern. Rather, it is a mark similar to a scratch.
This is a common type of fingerprint found at murder scenes, but it is also the most difficult type of fingerprint to identify and analyze.
Due to the influence of friction, the fingerprint has been completely deformed. Except for some fingerprint lines at the beginning and end, it is impossible to detect other places.
Dragging the fingerprint into the snapseed photo editing software, Lu Chuan first processed the edges of the blood print.
Then use your own software program to convert the images. Everyone heard the clicking sound of keyboards again.
Gao Wenxiang once again saw the data flow on the screen like a hacker attack. The people behind Lu Chuan were also stunned.
When they were processing Lu Chuan's first fingerprint, they only heard the sound of keyboard tapping, but they did not see the data flow on Lu Chuan's computer screen like Gao Wenxiang.
Is this fingerprint identification analysis? The picture detectives of the criminal investigation detachment are not very good at processing images, right?
Lu Chuan continued to process fingerprints, and more and more people were watching behind him. More than a dozen people gradually ran behind Lu Chuan.
Sun Hao, in particular, was almost lying on Lu Chuan's back, his eyes fixed on Lu Chuan's operations. Technically speaking, Sun Hao, as a police officer specializing in technical investigation at the Technical Appraisal Center, must be more comprehensive than the people in the units below.
However, he himself also knows that in terms of technical level, he is only one level higher than others.
From the fingerprint battle organized by the city bureau, it is already the limit to gain something. But when it comes to old murder cases...if he had that ability, the cases wouldn't be backlogged.
Therefore, Lu Chuan's success in the murder competition means that the other party's skills are not a little bit better than his and everyone else's.
If you don't steal from your teacher at this time, you will look down on yourself. This stop lasted almost another two hours.
More than a dozen people gathered behind Lu Chuan, watching as the other person marked the characteristic points of his fingerprints, compiled the data, and dragged it into the system to start comparison.
Then, within a few minutes, the familiar yet somewhat unfamiliar ding-dong sounded again!
