1995, Starting as a Criminal Investigation Expert

Provincial government office building.

He Guangming had half a floor of rooms vacated for fingerprint comparison work.

When Li Shu and his group arrived, work had already begun.

They're moving the fingerprint cards over here in stacks.

"Old Zhou, it's been 14 years, and we're fighting together again." A middle-aged man with graying temples and thick-rimmed glasses came up and hugged Zhou Xuewen.

Jing Lei.

Currently serving as the director of the Criminal Science Institute of Zhangxi Provincial Department.

"Yes, we're fighting together again."

Zhou Xuewen was filled with emotion. Back then, 400,000 fingerprints were sent to Matsuura, and it took three months to complete the comparison. Jing Lei was among them.

Conditions were even worse then. For three whole months, they persevered entirely on a fighting spirit, determined to solve the case.

Jing Lei pulled Zhou Xuewen along and quickly looked around all the rooms, asking Zhou Xuewen if he had any other requests.

"Look, I've already prepared the cot."

Each room has two folding beds placed in a corner, so you can rest whenever you're tired.

Therefore, it's no exaggeration to say that this was a battle.

Zhou Xuewen shook his head and said no, he came to fight, not to enjoy himself.

"By the way, Lao Zhou, what secret weapon did you mention before?" Jing Lei asked.

When asked about this, Zhou Xuewen kept it a secret and asked Jing Lei to gather everyone together for a meeting.

Sharpening knives does not miss woodcutters.

First, everyone needs to be familiar with the rapid location method, and then the existing fingerprint database needs to be pre-screened.

"Li Shu, you speak."

In the conference room, Zhou Xuewen pushed Li Shu to the front.

Li Shu had previously worked at a branch office, where he introduced methods to people. He was experienced and not intimidated.

Holding a simple locator, he explained the method and principles to everyone.

At first, the people present were a little surprised that Zhou Xuewen had pushed a young man onto the stage.

But as soon as Li Shu began his introduction, everyone's attention was instantly drawn to him.

From the side, Jing Lei exclaimed in surprise and quickly asked, "Old Zhou, is this your secret weapon? Who came up with it? You?"

After listening, he quickly realized the beauty of this method.

Zhou Xuewen shook his head, pointed at Li Shu, and said, "It's this kid. Also, the reason we were able to extract the fingerprint a second time and complete the middle finger fingerprint is entirely because of him."

Jing Lei was startled again.

He assumed Li Shu was from 803, and couldn't help but think to himself, "Wow, 803 is full of talented people."

Just as I was about to ask Li Shu for more details, Li Shu finished speaking.

Zhou Xuewen immediately stepped forward and said to everyone, "Li Shu will be in full charge of this fingerprint comparison. If you have any questions about the localization method, ask Li Shu. As for the arrangements for the comparison work, follow Li Shu's instructions."

"There's also the comparison process. If you encounter a fingerprint you're unsure about, you can contact Li Shu, and he'll make the judgment."

Upon hearing this, not only was Li Shu stunned for a moment, but the crowd below also erupted into a frenzy of whispering among themselves.

"Director Zhou, this won't do," Li Shu asked hurriedly.

If you don't understand something about the localization method, it's fine to ask yourself. But it's absurd to try to judge and decide on fingerprints you're unsure about.

Normally, for fingerprint comparison work of this scale, an expert is needed to oversee the process and make the final judgment.

With my qualifications, I'm afraid I'm not qualified.

Zhou Xuewen snorted and said, "You're even better than me. If I say you can do it, then you can."

The process includes partition comparison, localization method, processing of incomplete and blurry fingerprints, and even the secondary extraction of fingerprints.

Li Shu is young.

However, there is a sequence to learning, and in the area of ​​fingerprint comparison, Zhou Xuewen truly felt that Li Shu was more capable than himself.

Li Shu will not shirk this responsibility.

After saying this, without giving Li Shu a chance to refuse, he addressed everyone: "Everyone, this mission is related to whether we can find the suspect, so please follow our instructions and work together to solve this 14-year-old cold case. Zhou Xuewen thanks you all."

He bowed deeply to everyone.

The murmurs below immediately subsided.

Although we are still shocked by Zhou Xuewen's decision, who can say anything about his attitude?

"Chief Zhou, you're too kind. You're right. We're here to solve the case. Whatever you say, we'll do." A man in the front row said loudly.

He is Cao Yuanwei, the captain of the technical team of the Hongcheng City Public Security Bureau.

The group exchanged glances and nodded in agreement.

The goal is the same; everything else is meaningless.

"Li Shu, right? Tell me, what are we going to do next?" Cao Yuanwei looked at Li Shu.

Li Shu looked at Zhou Xuewen with a resentful expression.

This is truly forcing someone into a corner.

The problem is that you should have told me beforehand. Now you've caught me completely off guard.

"Don't overthink it, just do it your way. If anything goes wrong, I'll take responsibility." Zhou Xuewen patted Li Shu on the shoulder and left.

Li Shu sighed softly, composed himself, and decided to go all out.

At that moment, the people present were asked if anyone still had any questions about the positioning method.

Of course.

Li Shu immediately asked him what he didn't understand.

side.

Jing Lei looked on incredulously and asked blankly, "Old Zhou, what do you mean by this? Training... a successor?"

803 does have this tradition of experienced members mentoring new ones, but Li Shu is too young.

Moreover, with such a big case, if an old guy like you doesn't step up and lets a young person take the lead, aren't you afraid of problems arising?

Zhou Xuewen stared intently at Li Shu on the stage and smiled, "What a great opportunity! And don't worry, this kid is very capable, he'll be fine."

The reason for doing this is, on the one hand, because all the new progress in the case is due to Li Shu.

When it comes to technology, Li Shu has the most authority to speak on the subject.

Secondly, during the past few days, while Li Shu was staying in Songpu, Han Jianjun even called to ask him to take good care of Li Shu and guide him.

Han Jianjun's idea was to have Zhou Xuewen and other veteran experts teach Li Shu properly.

Zhou Xuewen's understanding was slightly off.

He thought Han Jianjun was grooming Li Shu as his successor.

That's normal.

Li Shu is young and has strong professional skills; such talent should definitely be nurtured.

In Zhou Xuewen's view, as a successor, it is not enough to just have professional skills; one must also have management and leadership experience.

How to lead a team well and how to bring out the full potential of everyone are both very important.

Given such a good opportunity, Li Shu should definitely give it a try and gain some experience in advance.

That's why this arrangement was made.

As it turns out, Li Shu, who was forced into this role, did a pretty good job.

The main reason is that they have strong business skills.

The positioning method was invented by Li Shu. Even if you don't understand it, Li Shu can teach you.

Li Shu had clearly already prepared a detailed work plan.

The first step is pre-screening, which reduces the workload.

For example, Li Shuding's age range is 30 to 60 years old.

According to the investigation records, the suspect was around 30 years old at the time of the crime.

Fourteen years have passed; this person should be around 45 years old now.

Secondly, there's the fingerprint pattern.

Because it wasn't just one middle finger fingerprint, multiple fingerprints were collected.

Although the other fingerprints were blurry, there were at least three fingerprints from which Li Shu could deduce the pattern.

Those three conditions, once set, can filter out the majority of cases.

"Director Zhou, I think we can hire more people for the pre-screening part. They don't need to know fingerprint comparison; they just need to look at the information on the fingerprint cards. Let them do the screening, and we'll do the comparison. This will improve efficiency a lot," Li Shu said to Zhou Xuewen, offering his idea.

The fingerprint card contains the user's age and records the fingerprint pattern of each finger; you can simply filter according to the criteria.

This is a job that anyone can do.

Zhou Xuewen's eyes lit up, and he nodded repeatedly: "This method is good."

Immediately, he went to find He Guangming and asked him to arrange for someone to help.
