1995, Starting as a Criminal Investigation Expert

The technical team's room is specifically for installing the AFIS system.

Liu Weikun was pointing at the computer screen, discussing with Li Shu whether there was still room for improvement and adjustment in the system after the software update.

"I think we could change the encoding method."

The AFIS system also categorizes and encodes data based on the date of collection, gender, finger used, and even tattoo type, forming a database.

"I've thought about the encoding method you mentioned carefully, and it's quite interesting. It's perfect for the function you mentioned of directly searching the database."

Liu Weikun shared his thoughts, then said, "Li Shu, really, I'm starting to admire you. How did you come up with these methods?"

As they were talking, they realized that Li Shu was lost in thought and hadn't been listening at all.

He waved his hand in front of Li Shu's eyes.

Li Shu came to his senses and hurriedly asked him what he had said.

Just as Liu Weikun was about to speak, Peng Rong poked his head out from the doorway and patted the door frame: "Li Shu, the task force is going to make an arrest. Get ready to go to the scene."

Li Shu jumped up.

I told you so.

The task force has been working hard for so many days, but they still haven't found the suspect.

Yesterday, the suspect was finally identified. How could they resist the urge to arrest him?

Moreover, the fingerprint match was irrefutable evidence, providing ample grounds for arrest.

I hurried outside, where preparations were already underway.

Wei Dejun is installing a camera.

The entire arrest process may need to be recorded.

It's a major case after all, so we need to keep a record of it.

Zhao Yong told Li Shu to pack his things, as they needed to examine the suspect's house and search for physical evidence.

Han Jianjun briefly explained the situation, stating that they would be divided into two teams.

Finally, he said seriously, "When you get to the scene, follow orders. This is no joke; the suspect may still have a gun."

These words were clearly meant for Li Shu and Tan Guoxiong.

Everyone went downstairs.

The task force members were boarding the vehicles in droves.

"Old Han, this way, get in this car." Xu Qiang called out from afar.

The group squeezed into a Toyota Hiace.

There are people inside the car.

Lin Wanping was pulling the bolt to inspect a Type 79 assault rifle.

Upon seeing Li Shu, his eyes lit up, and he quickly made way for him, waving to Li Shu: "Come, Li Shu, sit here."

Li Shu hesitated for a moment, then sat on the inside of him.

He chuckled, wrinkles crinkling at the corners of his eyes, and seeing Li Shu staring intently at his submachine gun, asked, "You like guns?"

That's a good question.

One of the biggest reasons Li Shu wanted to become a criminal police officer was that he wanted to be armed.

When I was a child, my maternal grandfather was the militia captain, and his family had many guns, including machine guns.

Their team also has a mortar, which Li Shu observed during training.

Therefore, Li Shu has liked guns since he was a child.

"Feel it!"

Lin Wanping handed him the submachine gun.

Li Shu familiarized himself with the bolt-action mechanism, gesturing as if he had handled this gun before.

The magazine capacity is too small, only 20 rounds, and it's empty in two or three seconds.

He handed the gun back and asked what was going on.

I tried to ask Shen Chuan about it, but I didn't run into him.

Lin Wanping smugly hummed, "What could it be? Arresting people, of course. Li Shu, you deserve the most credit for finding the suspect this time, right, Chief Xu?"

He shouted to Xu Qiang in the passenger seat.

Li Shu quickly shook his head, saying it was too exaggerated.

Han Jianjun, sitting in the back row, reached out and pressed down on Li Shu's shoulder, saying, "Whether it's the top credit or not, it's not up to us to decide. That's what the leaders decide. Anyway, the fingerprint comparison played a big role this time."

Xu Qiang turned his head, laughing and crying at the same time, and said, "Old Han, what are you saying? What, are you afraid I'll steal your credit?"

Han Jianjun scoffed, "I didn't say that."

He wasn't trying to claim any credit, but rather wanted to take the opportunity to show his superiors that criminal science and technology were truly useful.

The cases that your task force can't solve no matter how hard they try, in the end, you still have to rely on technology.

With this understanding, the bureau can increase its investment in the technical team.

They say it's been upgraded from a squadron to a brigade, but I haven't seen any real benefits.

It's the same people, the same equipment.

Han Jianjun thinks far ahead.

He wants not only the AFIS system, but also DNA matching equipment.

That way, when the DNA needs to be checked later, it will have to be sent to the provincial department for comparison.

The convoy drove a short distance before separating.

Xu Qiang's team headed towards Tingyang.

Lin Wanping is always willing to answer any question.

Li Shucai realized that the plan was to act simultaneously.

However, the focus is on Cheng Jianrong.

Because they conducted an analysis and concluded that Cheng Jianrong was the mastermind behind the entire crime.

Especially during the robbery of the armored truck, Cheng Jianrong committed murder, while Jin Zhenjiang was only responsible for riding the motorcycle.

Based on the initial investigation, Jin Zhenjiang is a bit of a scoundrel, but not ruthless enough.

On the other hand, Cheng Jianrong learned some information from Ha Chun, who said that this person was a notorious ruthless fighter in his hometown.

He was later caught robbing someone and sentenced to 11 years in prison without any reduction in sentence. He was only released after serving his full sentence.

This is enough to prove that he has no remorse whatsoever.

"We checked the vehicle inspection list, and guess what? This guy's name was on it. Shortly after the incident, around nine o'clock, he was stopped at the intersection of Qianjin Road on his way back to Tingyang."

"Then we asked the people who checked the car, and they had no recollection of him at all. What does that mean?" Lin Wanping asked rhetorically.

Just over half an hour ago, this guy coldly killed three people. When the police stopped him to check his car, he didn't panic at all. That takes a lot of mental fortitude.

Li Shuyi thought so too.

Those who have committed crimes will turn weak in the knees when they see the police.

This guy, without batting an eye, killed three people in a row. When faced with police questioning, he was able to handle it calmly. His mental fortitude is truly terrifying.

That's probably why we didn't notice him when we checked the car.

"Team Leader Lin, you'd better be careful," Li Shu said.

Lin Wanping nodded slightly and said, "There are armed police here, so there's nothing to fear."

Yesterday, we confirmed Cheng Jianrong's identity and immediately made arrangements to put him under surveillance.

He came to Nanjiang in the first half of the year, and at the end of May, he found a job at an equipment manufacturing plant in Tingyang, but he resigned in July.

According to the information on his temporary residence permit, he lives in Sifangqiao Village, near a cotton mill.

When they arrived nearby, people who were on-site to keep watch came up to them and said that the person had come out and was wandering around the area.

Xu Qiang glanced at his watch; it was a little past 3:20 PM.

He frowned immediately. What was he doing out for a stroll at this hour?

"Have you been discovered?" he asked the man.

The newcomer frowned: "It can't be that bad, we hid it very well."

Xu Qiang turned and told Li Shu and the others to stay put, then got out of the car with his men and headed away into the distance.

Li Shu couldn't help but feel a little nervous, his gaze following Xu Qiang and the others as they walked away: "Captain Han, will everything be alright?"

Han Jianjun thought for a moment, then shook his head and said, "Probably not, there are armed police here."

Li Shu nodded, hoping that nothing bad would happen.

But one can't help but think that there is still a difference between technical police and criminal police.

Right now, I can only wait in the car, completely in the dark, with no idea what's ahead.

Li Shu couldn't help but think again.

Actually, last night when I was going to sleep, I suddenly had this idea.

In this case, it's clear that I made a contribution by matching the fingerprint using the partition comparison method.

Li Shu then wondered if he could take this opportunity to make a small request to his superiors to transfer him to the criminal investigation team.

I feel there is hope.
