Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 160

"Little Lu, are you working so early?"

"How was the Spring Festival?"

Lao Bai looked rosy, and his mental state was better than Yang Sen's.

"It's okay, just eat, drink, and rest for a few days."

After the pre-processed fingerprints have been completed, Lu Chuan has carried out feature point marking and data calculation.

At this moment, the fingerprint has been dragged into the fingerprint comparison system, and the result is expected to be available in a few minutes.

"Brother Bai, look at your red face, you must have a good rest during the Spring Festival."

It is currently surveying different front lines, and there is no need to be on duty during the Spring Festival.

Lao Bai nodded: "It's another year closer to retirement, so I'm in a good mood."

Lao Bai's birthday is big, in January, and now he is 56 years old.

There are still four years to go, as long as they live in peace and stability, Lao Bai's happy life will be just around the corner.

yawn...

"Brother Yang," looking at Yang Sen who was yawning long, Lu Chuan stood up and took a cup of tea: "What's wrong with you, listless? Did you stay up late yesterday?"

Yang Sen's eyes were darkened, and his face was dull. It looked like he hadn't rested well.

Then Yang Sen yawned again and poured down a mug of tea: "Don't mention it."

"There are 7 days of Chinese New Year holidays. Except for the night when we went to Wang Ju's house for dinner, I accompanied my son to study for 6 days, and I went to bed at midnight every day."

He yawned again: "I got up at seven o'clock in the morning to read in the morning..."

"Study now... I didn't do it back then."

Lu Chuan and Lao Bai looked at each other and shook their heads.

They can't help with this.

In fact, Yang Sen's son was quite relieved.

At least I know how to study, and my grades are not bad.

In the preliminary examination years ago, I heard from Yang Sen that I scored more than 570 points.

This result is already very good.

As long as you keep going and recruit in batches in advance, Public Security University is similar.

And now there are still four months before the college entrance examination, and if I work hard, I might be able to score [-] points.

With this score, you can go anywhere.

Lu Chuan went to university with this score back then.

It's just that Lu Chuan didn't seem to have worked so hard back then.

Maybe it was like this too, but forgot?

The third year of high school is a magical time period. Many things seem to be very impressive, and many things seem to be forgotten.

Lu Chuan only knew that no matter what his academic performance was, it was a time of desperation.

Of course, Yang Sen's family is not the only child in the Criminal Investigation Detachment to take the college entrance examination this year.

When people reach middle age, they are all anxious things.

Letting out a long breath, Yang Sen patted his head: "Okay, don't talk about this."

"Little Lu, why are you so busy so early in the morning?"

The early morning tradition in the current survey office is to drink tea. After Lu Chuan came, he had a new hobby, growing flowers.

"Oh, it's nothing." Lu Chuan shook his head: "During the holidays a year ago, I went racing with my cousin and found a fingerprint at the racing track. It looked familiar. I didn't have time a few days ago. I went to work today. Run through the system to see if there is..."

Ding!
Before Lu Chuan finished speaking, there was a crisp sound from the computer.

The three of them are very familiar with this voice.

"Compared?"

Yang Sen looked astonished, just now he wanted to ask Lu Chuan where the car was racing, so that's it?

Lu Chuan was also a little surprised.

That day, I just felt that the fingerprints in the photo were a little familiar, but I didn't take it seriously.

It's like meeting women who look like your ex-girlfriend on the street, you can't go up and scold them one by one.

"See what case it is?"

Lao Bai walked to the computer first.

Dang!

As a result, the enamel jar in his hand fell to the ground.

"Old Bai, what's the matter?"

Yang Sen and Lu Chuan came over, and Lao Bai pointed at the screen: "You...you...you...see for yourself!"

The comparison is successful!

"The case of falling from a building 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, and this case was also within the scope of the thirteen homicide cases in the fingerprint battle.

Moreover, because the fingerprint of the suspect in the case was consistent with that of the suspect in the murder case of criminal policeman Zheng Bin nine years ago, the case was reopened for a time.

Ren Qiang, the second operation team of the Criminal Investigation Detachment, was the person in charge of the fall from the building in the Qingjian Community.

It's just that the case that exhausted manpower and material resources back then had no results, even if it was restarted, there was no major progress.

Lu Chuan did not expect that the fingerprints he found at the racing track at random were successfully compared.

You know, it's not just that Qingjian community's fall case may be declared solved.

The murder case of criminal policeman Zheng Bin nine years ago, judging from the comparison of fingerprints, is the same murderer as the murderer who fell from the building in Qingjian Community!
7 minute later.

The meeting room of the morning meeting of the criminal investigation detachment.

With such a big discovery in the current survey, it is obvious that the Spring Festival heart-warming meeting cannot continue.

Qin Yong listened to Lu Chuan's report on the spot.

"The suspected fingerprint was found on the 29th day of the twelfth lunar month before the Spring Festival, at the No. [-] racing track."

"That racing track in the northern suburbs?"

Qin Yong obviously knew this place.

Lu Chuan nodded: "It's the racing track. The fingerprint was found on a photo at the time. It feels a bit familiar, so I took a photo that day."

"I went to work today and did an appraisal analysis, and compared with the case of falling from a building in Qingjian Community five years ago."

"Furthermore, I studied the fingerprints of the suspect in the Qingjian residential building fall case when I participated in the fingerprint battle, and they are consistent with the fingerprints of the murderer who was killed in Miaowang Mountain nine years ago by Zheng Bin from the Criminal Police Brigade of the Water District."

One fingerprint, two cases solved.

"Is there any information about this person?"

Lu Chuan nodded: "Yes, Wang Qi, from Sanyo Auto Repair Factory, is a car modification master."

"Anything else?"

"that's it."

The part that Lu Chuan is in charge of has been completed.

All that's left is to arrest people and interrogate them.

"Ren Qiang!"

"You were responsible for the Qingjian community case five years ago, and you are responsible for the arrest!"

"Yes!"

Ren Qiang had been gearing up for a long time. Although it had been five years since the falling from a building in Qingjian Community, he was not the leader of the operation team at that time.

But basically every year, the case is taken out and studied.

Occasionally, when driving past the Qingjian community, Ren Qiang couldn't help but go in and take a look around.

Half a month ago, the case made significant progress.

The murderer of the falling case in Qingjian Community was the same suspect who was murdered nine years ago by criminal policeman Zheng Bin from the Criminal Police Brigade of the Water District.

Unexpectedly, after only half a month, Lu Chuan directly locked the suspect's information!

Sanyo Auto Repair Shop!
Wang Qi!

Let's see where you go this time!

Moreover, 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.

All had DNA taken, but none matched the residual bodily fluids found in the deceased.

Based on the time of the other party's death, there should be no omissions in the investigation even though there were people who had entered and left the Qingjian community at that time.

How did the other party do it?
