1995, Starting as a Criminal Investigation Expert

Li Shu instinctively reached for the car.

Xu Qiang, with his sharp eyes, turned around and stopped Li Shu.

"Don't go, it's dangerous."

If something happens to Li Shu, Tang Weidong will risk his life for him.

After saying that, he slammed the car door shut and sped away with several elite soldiers.

Too many people will hinder the team's ability to operate effectively.

Jiao Xiaodong was also left behind, his mind still in shock: They've already found the suspect?

He certainly knew the importance of fingerprints; they're the king of evidence.

But in his mind, solving cases was the job of criminal police.

Through investigation and visits, starting with details that are difficult for ordinary people to notice, and peeling back the layers, the suspect was finally identified.

What happened to Li Shu?

Without leaving the car, just sitting there scanning a fingerprint card, they managed to catch the suspect.

"He's really that amazing." Jiao Xiaodong nudged Tan Guoxiong beside him.

Tan Guoxiong nodded, thinking to himself that it was more than just impressive.

In his view, there are two definitions of fingerprint expert. One is that they are good at fingerprint comparison itself, skilled and proficient, which is the ultimate skill.

Just like those who study medicine, the first type is the kind who follows the steps, is proficient in the medical skills of their predecessors, and can solve 99% of diseases.

But they are powerless when faced with the remaining one percent of difficult and complicated diseases, because they are not mentioned in medical books.

The second type of expert is someone who can prescribe medicine, research prescriptions, and solve one percent of difficult and complicated diseases.

Li Shu reached this level.

If that's not impressive, then what is?

When Xu Qiang and his group arrived at the small hotel where their target was located, they heard the woman making a defense before they even entered the room.

"Officer, we really are a couple. Don't let his looks fool you, he's kind-hearted. That's the kind of person I like. As the saying goes, inner beauty is true beauty."

Xu Qiang slowed his pace and walked forward slowly, taking in the situation inside the house.

The room wasn't big, and there was only one bed.

A young man wearing boxer shorts was squatting in the corner with his head down.

A young woman sat at the foot of the bed, draped in a sheet, arguing vehemently.

Two colleagues were watching.

One person joked, "You like her, and you're even her boyfriend, but you don't even know her name?"

The woman retorted, "I already said we're pen pals, and we're looking for a Platonic relationship, so does a name matter? Absolutely not."

My teasing colleague laughed: "Don't think that just because I don't read books, you guys are so Platonic?"

The woman smiled seductively: "Officer, even if it's Platonic, it still has to be conventional. He insists on it, what can I do but satisfy him?"

As he spoke, he grabbed a pillow and threw it at him, cursing, "Why the hell aren't you saying something?"

The young man then looked up.

With a quick glance, Xu Qiang saw it clearly.

Medium-length hair, with bangs so long they almost cover her eyes.

The young lady was right when she said he was ugly.

It's not a problem with his facial features; his features are below average. The main issue is that he has a face full of acne.

It's extremely severe, reaching the level of acne, especially on the nose and both sides of the chin, with patches of it coming together, which can be quite physically uncomfortable to look at.

When the guards saw Xu Qiang and He Chenghua enter, they were about to greet them when Xu Qiang stopped them with a look.

Wearing only underwear eliminates the possibility of concealing a weapon.

With a single glance, Lin Wanping and another person surrounded them from both sides.

The next moment, the two of them had already locked Zhou Pan's arms tightly.

He shuddered violently and hurriedly cried out, "Officer, I...I was wrong, I shouldn't have solicited prostitutes, I...I accept the punishment."

"Hold!"

The woman next to him pretended to kick him.

Xu Qiang stopped them, waved his hand, and gestured for them to take him away.

Zhou Pan thought he had only been arrested for soliciting prostitution, so he cautiously asked if he could put on his clothes first.

"Damn it, I guess I'm just unlucky."

The young woman cursed a couple of times, crossed her legs, and said with a roguish look, "Anyway, I have no money and can't afford the fine. You can just send me to a labor camp."

He muttered to himself, "A fine of five thousand yuan, how many times would I have to stretch my legs to earn that back?"

Xu Qiang gave a wink, signaling that they should all be taken along, then turned and walked out of the room.

When they got downstairs, Zhou Pan had already been put into a police car.

He looked bewildered inside the car: It felt like there were... a lot of police officers.

Xu Qiang stretched.

It was still dark, but his heart was already filled with light.

He Chenghua, who had been standing silently to the side, suddenly said, "Old Xu, you guys are solving cases way too easily these days."

No visits, no stakeouts.

The technical investigation team will find a way to extract fingerprints, come up with ideas on how to find the suspect, and then help you compare fingerprints at the scene to identify the suspect.

What were those criminal police officers doing in the middle? Running errands?

Why do you talk so much?

Xu Qiang glared at him, grabbed him and made him treat everyone to dinner, and they went to Wangxingji Restaurant.

"This isn't my case, is it?"

I came here to help out, stayed up all night, and now I have to treat everyone to a meal.

The key is that we still have to eat Wang Xingji, what a big face!

Xu Qiang got into the car and said confidently, "Li Shu stayed up all night with us, shouldn't you show some appreciation?"

He Chenghua fell silent at the mention of Li Shu.

When Li Shu gave a lecture at the branch office last time, he felt it was necessary to cultivate a good relationship with Li Shu.

Now, I'll have to treat myself.

Since we couldn't get food at Wangxingji (the place wasn't open yet), we found an open breakfast stall nearby and a group of us drank tofu pudding.

While eating, He Chenghua said, "When I got there and saw his face, I knew it was going to work. It was him."

With that face full of pimples, it must have been so painful to hold it in.

Xu Qiang, standing nearby, snorted and said, "What do you mean 'probable'? If Li Shu matched it, then it can't be wrong. Do you know about the Jianfeng Hotel case in Matsuura?"

He Chenghua nodded and said he knew.

When 803 came to the scene, the Nanjiang Municipal Public Security Bureau assisted in handling the case, and the branch bureaus below also contributed their efforts.

"It was Li Shu who extracted fingerprints from the ventilation vent panel a second time. Fourteen years ago, he actually managed to complete the fingerprints and matched them with the suspect immediately," Xu Qiang said, shaking his head in amazement.

Fourteen years, two extractions—what does that mean?

He Chenghua's eyes widened in disbelief: "Then the case is solved?"

Li Shu nodded.

Just yesterday, Zhang Shenghua made a special phone call to the technical team to thank them again on behalf of 803, and also explained the situation of the case.

Ai Hongguang was arrested on the 13th and interrogated in a surprise raid.

This old man looks honest, but he's actually very cunning, constantly denying and refusing to admit anything.

He claimed he was illiterate and that he had never been to Matsuura, so he didn't even know how to buy a ticket.

Previously, that half fingerprint alone wouldn't have been enough to completely lock him down.

After all, he could argue that he had only touched the ventilation duct.

During the second fingerprint extraction, not only were the fingerprints completed and multiple incomplete fingerprints extracted, but half a fingerprint was also extracted from the blade.

This half of the fingerprint is the key.

The knife wrapped in the deceased's delivery slip is always connected to you.

Therefore, when this evidence was presented, Ai Hongguang's attempts to deny it were futile, and he had to admit it.

He's the one who killed him.

His motive was simple: his family was poor, he had three children to support, and his income couldn't cover his expenses. He also made a bunch of bad friends, which corrupted his mind, and he wanted to get rich overnight.

The reason for using electric shock was inspired by seeing people in the village using electric fishing.

After admitting it, he also defended himself, saying that he had planned to turn over a new leaf after his release from prison.

Why didn't you do that earlier?

"ox."

He Chenghua gave a thumbs up and said, "This is a case that the ministry is supervising. Even 803 couldn't solve it, but you managed to solve it. I'm truly impressed."

Li Shu hurriedly said it wasn't that exaggerated.

Ai Hongguang was imprisoned unexpectedly in 83, leaving behind a fingerprint record.

The fingerprint on the middle finger was already quite good; once a nationwide fingerprint database is established, it will definitely be able to match him.

So, as the saying goes, retribution may be delayed, but it will come eventually.

He Chenghua made a compliment, then suddenly paused, as if thinking of something. He pondered for half a minute while holding a fried dough stick, before tentatively asking, "Old Xu, if you can extract fingerprints from 14 years ago again, do you think there's any hope for that Yang Luxiang family annihilation case?"

Yanglu Lane?

Li Shu subconsciously looked up.

When we were clearing up old cases, there were a total of 16 unsolved murder cases.

Of these, seven fingerprints were collected on-site, including even blurry ones, and I have already resolved two of them.

However, no fingerprints were found at the scene of the Yanglu Lane family annihilation case mentioned by He Chenghua.

It was called a family annihilation case, but actually only two people died.

The reason no fingerprints were found was because the crime was committed cleanly and efficiently, and the body was not discovered until a month later.

If latent fingerprints are left within a month, the moisture will have dried up, making extraction impossible.
