Chapter 160 came with no effort
"Xiao Lu, are you working so early?"
"How was the Spring Festival?"
Lao Bai looked rosy. , The mental state looks better than Yang Sen.
“It’s not bad, just eating, drinking and resting for a few days.”
After completing the preprocessing of the fingerprint, Lu Chuan performed feature point marking and data calculation.
At this moment, the fingerprint has been dragged into the fingerprint comparison system, and the results will probably be available in a few minutes.
"Brother Bai, looking at your glowing face, you must have had a good rest during the Spring Festival."
The current survey is different and there is no need to be on duty during the Spring Festival.
Lao Bai nodded: "It's one year closer to retirement, so of course I'm in a good mood."
Lao Bai's birthday is in January, and he is now fifty-six years old.
There are still four years left. As long as he spends his time peacefully, Lao Bai's happy life will be just around the corner.
Yawn...
"Brother Yang," looking at Yang Sen who yawned for a long time, Lu Chuan stood up and took a cup of tea: "What's wrong with you? You're listless? You stayed up late yesterday. ?”
Yang Sen’s eyes were darkened and his face was dull. It looked like he had not rested well.
Then Yang Sen, who yawned again, drank a jar of tea and said, "Don't mention it." For 6 days, I went to bed at around one o'clock every night."
Yawned again: "I got up at seven in the morning to read..."
"Studying now...I didn't do it back then. That’s it.”
Lu Chuan and Lao Bai looked at each other and shook their heads.
There's nothing they can do to help with this.
In fact, Yang Sen’s son is quite worry-free.
At least I know how to study, and my grades are pretty good.
In the proficiency test years ago, Yang Sen said that he scored more than 570 points.
This result is already very good.
As long as you keep going and recruit in batches in advance, the Public Security University will be the same.
And there are still four months left before the college entrance examination. If I try my best, I might be able to score 600 points.
With this score, you can go anywhere.
Lu Chuan went to university with this score.
It’s just that Lu Chuan didn’t seem to have worked so hard back then.
Maybe you got through it like this, but forgot about it?
Senior year of high school is a magical time. Many things seem to be very impressive, and many things seem not to be remembered.
Lu Chuan only knew that no matter what his academic performance was, that was the time to work hard.
Of course, the Yang Sen family is not the only child taking the college entrance examination this year in the criminal investigation detachment.
When people reach middle age, they are worried about everything.
After letting out a long breath, Yang Sen patted his head: "Okay, let's not talk about this."
"Xiao Lu, why are you so busy so early in the morning?"
Now The early morning tradition in the survey office is to drink tea. After Lu Chuan arrived, he took up a new hobby, growing flowers.
“Oh, it’s nothing,” Lu Chuan shook his head: “During the vacation years ago, I went racing with my cousin, and I found a fingerprint at the racing track. It looked familiar. I didn’t have time a few days ago. At work today, I thought about running through the system to see if there is..."
Ding!
Before Lu Chuan finished speaking, there was a ding from the computer.
This kind of sound is familiar to all three of them.
“It’s a win?”
Yang Sen looked stunned. Just now he wanted to ask Lu Chuan where he was racing, but now it’s a win?
Lu Chuan was also a little surprised.
That day, I just felt that the fingerprints in the photo looked familiar, but I didn’t take them too seriously.
This is just like meeting a woman who looks like your ex-girlfriend on the street. You can't go up to them and scold them one by one.
“Let’s see what the case is?”
Old Bai walked to the computer first. Bang!
As a result, the enamel jar in his hand fell to the ground.
"Lao Bai, what's wrong?"
Yang Sen and Lu Chuan came over, Lao Bai pointed at the screen: "You...you...see...yourselves!"
Comparison successful!
“Falling case in Qingjian Community.”
Half a month ago, Lu Chuan came into contact with this case when he participated in the fingerprint battle at the city bureau. This case was also within the backlog of thirteen murder cases in the fingerprint battle.
Moreover, the case was once reopened because the fingerprints of the suspect in the case were consistent with the fingerprints of the suspect in the murder of detective Zheng Bin nine years ago.
Ren Qiang of the Second Operation Team of the Criminal Investigation Detachment was the person in charge of the falling case in Qingjian Community.
However, the case that exhausted manpower and material resources to no avail, even if it is restarted, has not made any major progress.
Lu Chuan did not expect that the fingerprints he randomly found at the racing track were successfully compared.
You know, this is not just the case of falling from a building in Qingjian Community that may be announced.
In the case of the murder of criminal policeman Zheng Bin nine years ago, judging from the fingerprint comparison, it was the same murderer who fell from the building in Qingjian Community!
Seven minutes later.
Criminal Investigation Detachment Morning Meeting Meeting Room.
With such a big discovery in the current survey, it is obvious that the Spring Festival Heart-receiving Party cannot continue.
Qin Yong listened to Lu Chuan's report on the spot.
"The suspected fingerprint was found at the No. 3 racing track on the 29th day of the twelfth lunar month before the Spring Festival."
"That racing track in the northern suburbs?"
Qin Yong obviously knows this place.
Lu Chuan nodded: "That's the racing track. I found a fingerprint on a photo. It felt a bit familiar, so I took the photo that day."
"I went to work today and did an identification analysis and found the fingerprint of the suspect in the Qingjian Community Falling Case five years ago." I did some research at that time and found that the fingerprints were the same as those of the murderer Zheng Bin of the Water District Criminal Police Brigade who was killed in Miaowang Mountain nine years ago. "
One fingerprint solved two cases.
"Do you have any information about this person?"
Lu Chuan nodded: "Yes, his name is Wang Qi, from Sanyo Auto Repair Shop, he is a car modification master."
"Is there anything else?"
"That's it."
The part that Lu Chuan was responsible for has been completed.
The rest is to arrest people and interrogate them.
“Ren Qiang!”
"You were responsible for the case of Qingjian Community five years ago, and you are responsible for the arrest!"
"Yes!"
Ren Qiang has been gearing up for a long time, and Qingjian Community fell. Although five years had passed since the building case, at that time, he was not the leader of the action team.
But basically every year the case is taken out and studied.
Occasionally when driving by Qingjian Community, Ren Qiang can't help but go in and take a look.
Half a month ago, the case made significant progress.
The murderer of the falling case in Qingjian Community turned out to be the same person as the suspect who killed police officer Zheng Bin of the Water District Criminal Police Brigade nine years ago.
Unexpectedly, just half a month later, Lu Chuan directly locked the suspect’s information!
Sanyo Auto Repair Shop!
Wang Qi!
Let’s see where you go this time!
Furthermore, one thing Ren Qiang really wanted to know was how the murderer escaped from the police's sight in the first place.
You know, in order to catch the murderer, the entire Qingjian Community was turned upside down.
Everyone has collected DNA information, but no one matches the residual body fluids found in the deceased.
Based on the time of death of the other party, there should be no omissions in the investigation of anyone who had been in and out of Qingjian Community at that time.
How did the other party do it?
