Chapter 138: Homicide
Gao Wenxiang was stunned.
I touched my 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 going on?
A few of us just smoked two cigarettes, which is not considered fishing.
Why is the director here?
"Wang Bureau..."
Wang Kai passed Gao Wenxiang and ran straight to Lu Chuan behind him, his eyes seemed to be shining.
The fingerprint battle is held every year by the Haizhou City Public Security Bureau.
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 the fingerprint battle for a week, which would make people laugh.
So, 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 are 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 within two hours of the mobilization meeting, shocking news would come 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 came off the night shift early in the morning and was killed in the bushes.
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.
A 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 temporarily and randomly. There are no clues except a half-fingerprint twisted into a mess on the stone.
As for this fingerprint, Wang Kai specially asked experts from the provincial department to conduct identification and analysis.
After trying it two or three times, the comparison was not successful.
Now, in the fingerprint battle organized by the Haizhou City Public Security Bureau, it was successfully compared!
Wang Kai arrived at the battle conference room immediately.
The case seven years ago?
Lu Chuan nodded: "You mean the case in the High-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.”
While speaking, 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 target whose fingerprints were successfully compared: "It is indeed him!"
"Lu Chuan, good job!"
"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 stared with big eyes. Gao Wenxiang stammered: "Brother Lu... have you been hit by a murder case?!"
The others have just met. Lu Chuan's detective 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 knows about the case of the Hi-tech Zone Cultural Park seven years ago.
Especially Gao Wenxiang, the case came from their high-tech zone.
He was also involved in the detection of the case back then, so he knew better than anyone else what the virtue of the fingerprint involved in the case was.
That was the fingerprint that was not matched in the provincial fingerprint battle.
Lu Chuan...did it in two hours?
Sun Hao also came over.
Fingerprint identification analysis, there is no shortcut.
If you win, you will win. If you miss, you will miss.
He was familiar with the fingerprint in 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 doesn't care too much. With his advanced fingerprint identification and analysis capabilities, as long as there are fingerprints of the target person in the fingerprint database, there will be no problem if he fails to compare: "Better luck."
As a person, he still shouldn't be too high-profile. Lu Chuan said hello to the few policemen who were smoking together just now, and he didn't care that everyone was surrounding him.
Of the remaining twelve murders, one was randomly selected.
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 outer door frame of the deceased's home.
Because it was stained with blood and had traces of friction, the fingerprints did not show the usual pattern.
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.
Drag the fingerprint into the Snapseed photo editing software, Lu Chuan first performs edge processing on the blood print.
Then use the software program you compiled to convert the image.
Everyone heard the clicking sound of keyboards again.
Gao Wenxiang once again saw the data flow on the screen as if it were 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 facing an old murder case...
If he had that ability, the case would not become a backlog.
So, Lu Chuan's success in the murder competition means that the opponent's skills are not a bit better than his and everyone else's.
If you don’t steal from others 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 fingerprint, prepared the data, and dragged it into the system to start comparison.
Then, within a few minutes, the familiar yet somewhat unfamiliar ding-dong sound sounded again!
