1995, Starting as a Criminal Investigation Expert

Everything is for solving the case; if a method works, then we'll use it.

Xu Qiang then came over and had a serious discussion with Han Jianjun, eventually defining a scope.

Male, between 1.65 and 1.85 meters tall.

Ages 20 to 40.

Weight between 110 and 160 pounds.

Since it is still uncertain who owns this half of the fingerprint, the characteristics of the two suspects can only be combined.

Under these conditions, a large portion of the fingerprint cards have already been filtered out.

To improve efficiency, they even called over the bureau's internal staff to help screen the fingerprint cards.

If the conditions are met, the data will be entered into the system first.

The coding classification method proposed by Li Shu has not been adopted yet.

This increases the workload, and the system also needs to modify the corresponding code to meet the requirements for building a small library.

However, Liu Weikun has already discussed this idea with his team and considers it a good approach. He will update the information later.

Right now, he's with Li Shu, listening to Li Shu's methods for comparing incomplete fingerprints, and then summarizing the functions that need to be optimized in the system.

In order to use the partition comparison method, the first function required is for the system to provide a partition comparison tool.

That is, to delineate a specific area within the system's coordinate system.

At the same time, allow for some leeway, letting the system move and scale on its own to ensure coverage of a slightly larger area, so as not to be too rigid and to improve the success rate.

In addition, Li Shu also proposed many other methods for the system.

In the past few days, Li Shuzhen has spent a lot of time researching and understanding the other methods provided by the system.

For example, there is a method in the system called the "Feature Comparison Method".

Instead of comparing all features, we manually remove some features to broaden the comparison scope, and then manually screen them one by one.

"Therefore, we need to add a function to add or remove specific feature points."

At the same time, staff should be allowed to modify the features of the target fingerprint.

Furthermore, a separate database search function should be added.

This means that instead of inputting the target fingerprint, you manually extract feature points from the fingerprint, such as what feature points and how many of them are in a thumb fingerprint.

Then set the conditions to filter directly from the system fingerprint database.

In other words, these methods of the system, as Liu Weikun said, are simply treating the fingerprint comparison system as a tool to improve their work efficiency.

The comparison process should be human-led, rather than entirely relying on machines and having people blindly perform the comparisons themselves.

Liu Weikun gripped his notebook, just like in class, constantly recording Li Shu's requests and ideas, and then silently calculating the possibility of making them a reality.

After listening to the whole thing, he couldn't help but say, "Wow, you've practically rewritten the entire control program we made!"

He considered it.

Implementing the features Li described is not as simple as staying up a few nights and adding some code. It may require a significant overhaul of the program's underlying code.

It's a huge project, and the workload is considerable.

But he had to admit that these were all good suggestions for improvement, and they were truly based on reality.

If successful, it can greatly improve the system's comparison efficiency.

"Is it possible?"

Li Shu couldn't help but feel nervous.

I'm afraid they'll make too many unrealistic demands.

Liu Weikun patted his chest and said proudly, "Dude, I graduated from Peking University."

That's a very direct and definitive statement.

Li Shu remained silent, knowing that it was just an undergraduate degree.

Dozens of people worked together to screen more than 60,000 fingerprint cards.

There are still many.

But it has greatly reduced the workload.

While the data was being entered simultaneously on one side, Liu Weikun was in high spirits on the other, barely resting, constantly calling and emailing the team at Anjing to optimize the program.

Before we knew it, another day had passed.

Without even asking around, when they didn't see anyone from the Criminal Investigation Division while eating in the cafeteria, they knew the case wasn't going well and they still hadn't found the person.

The task force requisitioned a large conference room.

Meanwhile, the office of the First Brigade was also requisitioned.

On the morning of the 9th.

As dawn broke, many people were lying sprawled out in the office.

Xu Qiang entered the room and woke them up one by one.

"Comrades, I know you are very tired." Xu Qiang's eyes were red.

He barely rested during those four days, just pushing himself to the limit.

Moreover, it wasn't just physical exhaustion; he was also the deputy head of the task force, which meant he had to shoulder even greater pressure.

"But we only have one day left, just one day!"

Xu Qiang raised one finger.

He didn't need to say anything; everyone present remained silent, their faces grim.

The deceased was lying in the morgue, and his family members came to inquire about him more than once.

But the suspect still hasn't been found.

"Get to work!"

Lin Wanping picked up his briefcase, grabbed two steamed buns from the conference table, rubbed his face, and walked out.

Xiao Rui stepped forward, winking hard, but his eyes still felt dry. He then said, "Chief Xu, it's the last day. We still need to figure out a way. If we continue like this, we really won't have enough time."

The task force now has only two directions left.

First, we will check motorcycles.

We visited every motorcycle owner in the city.

Meanwhile, the repair shops mentioned by Li Shu are also being visited continuously.

Secondly, we need to continue organizing our forces to search for the location where the suspect hid the money box, centered around the crime scene.

The remaining information, such as the migrant population and hotels, was investigated, but no results were found.

"The lockdown was partially lifted yesterday, so the suspect might take some action, but that's just a possibility."

Such a high-intensity lockdown obviously cannot last long.

Just three days.

Starting yesterday, all road closures except for those on roads leading out of the city and major roads within the city have been lifted.

Another reason for doing this is to create a relaxed environment for the suspect.

Then they might set out to search for the money box, or escape.

This created an opportunity for the task force to arrest them.

But the prerequisite is that you can find the money box.

But within a radius of several kilometers, it was like searching for a needle in a haystack; we really couldn't find it.

Xu Qiang also speculated that, twelve hours after the incident, fingerprints were collected from all the motorcycle owners who were found and compared with each other.

Unfortunately, the match still didn't work.

It can only be inferred that they had already fled home before the checkpoint was set up, or that they had a base near the crime scene and thus evaded the blockade.

"Chief Xu, how about we offer a reward?"

Xiao Rui gritted his teeth and suggested an idea: "Let's offer a reward of 20,000. I refuse to believe we won't get a single clue."

A generous reward will surely attract brave men; the power of the people is boundless.

Xu Qiang crossed his arms, frowned, and remained silent.

Bounties are a double-edged sword.

Perhaps we can gather some useful clues.

However, sometimes this can alert suspects and lead to unpredictable consequences.

Seeing Xu Qiang remain silent, Xiao Rui knew his attitude and asked again, "How's the fingerprinting going?"

Xu Qiang shook his head slightly.

That's a system; you also have to record fingerprints and build a fingerprint database.

In Pingyu next door, the fingerprint database alone took more than half a month to develop.

It's already quite an achievement that Li Shuneng was able to propose a method to optimize and improve this speed; he really can't expect too much.

Taking a deep breath, Xu Qiang said, "Old Xiao, we're currently in a stalemate. The more this happens, the more you need to hold on and stay focused."

"Trust me, we're on the right track. Keep an eye on the motorcycles, and we'll find them sooner or later."

It's not that Xu Qiang didn't want to think of other ways, it's just that these were the only options he had.

We can only persevere, like building a tower from grains of sand. As long as we remain in the city, we will eventually make a discovery.

The only problem is that the deadline is approaching.

"As for the reward."

Xu Qiang paused for a moment, then said in a deep voice, "Send it after midnight tomorrow."

He nodded to Xiao Rui, then turned and left.

Xiao Rui let out a long sigh.

If the reward is issued after midnight tomorrow, it's tantamount to admitting that the task force has failed and the suspect has not been caught.
