There is a direction for solving cases, and the police have never lacked executive power.

In less than an hour, the cash and envelope had already been handed over to Lu Chuan.

"I'll go back to the detachment, and there's no fingerprint collection here."

Fingerprints on cash and envelopes can be easily extracted with a variable frequency laser scanner, or with a dedicated ultraviolet camera.

The Wah Kwong Street police station doesn't have such a thing.

In the past month, the criminal investigation detachment has changed its guns from top to bottom.

The 100 million donated by the wealthy Qiangsheng Group was already in place the day after Lu Jianguo spoke.

Where has Qin Yong seen so much money, you know, this is specially donated to the criminal investigation detachment.

As long as the unified decision of the detachment team is reported to the city bureau for approval, the bonus will be issued, and no one can say anything.

Of course, it is impossible to issue bonuses, and the Public Security Bureau often accepts donations, and there are relevant management norms.

For more than a month, Qin Yong has really experienced the pleasure of spending money.

Seven old police cars that were broken except for the horns that did not sound everywhere went directly through the scrapping process.

According to the regulations, these cars can be scrapped after being used for more than eight years and with a cumulative mileage of 200,000 kilometers.

However, due to financial constraints, it was overserved for more than five years.

This time, they were all replaced.

The canteen was completely renovated, and the dilapidated tables and chairs in the office had to be replaced.

The Survey Office has a large share in it.

The main thing is the update of experimental equipment.

For example, infrared ultraviolet digital cameras, which can directly extract fingerprint traces on smooth non-permeable and semi-impermeable object surfaces.

For example, fingerprints on the surface of objects such as glass, aluminum alloy or ceramic.

Another example is the full-spectrum on-site forensics instrument, which has a good effect on showing fingerprints on rough surfaces such as leather and banknotes, and is not easy to produce the phenomenon of pasting the bottom.

In addition, the laboratory has also added the most advanced field survey equipment such as portable multi-band light source, targeted discovery biological trace instrument, ultra-wide spectrum on-site trace evidence search camera, laser physical evidence exploration instrument, etc.

In addition to these, the Investigation Office is setting up a trace evidence laboratory.

"I heard the leader say that there is a case on Huaguang Street?"

Lu Chuan went back to the office first and showed his face, Yang Sen and Liu Guodong went out, only Lao Bai was there.

"Originally, I helped to do the fingerprint analysis of an electric car theft case, but I didn't expect to pull out other cases."

Lao Bai nodded, this kind of thing is very common.

Ordinary crime is not the same as homicide.

If you kill someone, you will probably kill one and you will be caught.

But the average petty theft is different, and you don't necessarily get caught once if you do it ten times.

Therefore, most of the time, engaging in this kind of case is sometimes like a bastard.

With one, there are many more to come.

"Master, they're out?"

Lao Bai snorted: "There is a scene over there in the Criminal Police Brigade of the High-tech Zone, and we need our support, Lao Liu and the others have passed."

"Big case?"

Major and important cases may not always be reported to the criminal investigation detachment, and the criminal police brigade below is not dry.

If all the major and important cases in Haizhou City were handed over to the criminal investigation detachment, then the current manpower would be ten times more and they would not be able to keep busy.

"Intentional injury, two people fighting, the woman cut the man, almost died, people are in the ICU."

"Two people fighting? Such a heavy hand?"

"Who knows, the neighbor called the police, if he hadn't gone early, he would have lost his life."

Lu Chuan nodded, he almost died, the case is not small.

"Brother Bai, you're busy, I'll go to the laboratory, take a fingerprint, and analyze it."

"I'll go straight to the Wah Kwong Street police station later."

"Okay," Lao Bai nodded with emotion, "Thanks to you, we have purchased a lot of new equipment this time.

」

"There's a lot of it that I won't use, hey, I'm getting old."

Lu Chuan smiled: "Equipment, that's it, it's almost the same if you fiddle with it a few more times."

"Okay, you go get busy, I'll go read the manual."

Detachment basement.

Lu Chuan quickly collected fingerprint information on envelopes and cash notes.

But not one, but a dozen.

It's still quite difficult to deal with.

An hour later, the 17 relatively clear fingerprints completed the pre-processing and were successfully compared in the system.

The result is very good, among the owners of these seventeen fingerprints, there are Zhang Baoku and Chen Wen.

Interrogation room of the Wah Kwong Street Police Station.

"Chen Wen, this is the cash received from Zhang Baoku, and the fingerprints taken from the cash envelope."

Lao Luo slapped an appraisal analysis report in front of Chen Wen.

"You think you're doing it seamlessly, do you think you can pick it up without direct contact with Zhang Baoku, without making phone calls, without transferring money?"

"What do you mean by that?"

At this moment, Chen Wen was already sweating like rain.

"The money...... Maybe it's just the ...... I've used."

"Happened to have used it? What about envelopes? You happen to have used the envelope for money?"

"I...... I."

Chen Wen's face changed sharply, and his mouth opened unconsciously, wanting to quibble.

But as Lao Luo said, there are more than a dozen fingerprints on the money, and Chen Wen can explain it with what he happens to use, but what about the envelope?

The envelope can't be the one you happen to use, right?

Chen Wen has a lot of dealings with the police, and he knows very well when he can pretend to be past and when he can't hide.

"I...... I'll confess, Officer Luo, I'll confess!"

In the face of ironclad evidence, Chen Wen explained the ins and outs of the matter.

"What's in the box...... It's ivory!"

Ivory?

"You sell ivory?"

Chen Wen drooped his head: "No, no, I don't resell, I'm the middleman, the transporter, I don't resell."

"Say! Tell me where the things came from, why they were sent to the Pine Forest Villa area, and who your last home is, all of them!"

"I said, I said ......"

It's relatively simple.

Haizhou City is a processing zone for the entire criminal chain.

"The Pine Forest Villa is responsible for continuing to process ivory, and I'm equivalent to a courier, really."

"Some antiques in my shop...... The handicrafts are all imported from Myanmar."

"It's hidden inside, and it's sent to me through logistics."

"I'll pack the things and hand them over to the next family, and they'll take care of the processing, and I don't know what happened after that."

"How do you know these people?"

"I went to Myanmar last year...... ...... of Knowing"

The chain of cases is already relatively clear.

Haizhou City is a link in the whole chain, responsible for processing the things sent by Chen Wen.

But the situation of the entire upstream and downstream industries, Chen Wen is not clear.

"Huang Suo, the people in the villa area, can you catch it?"

In the conference room, several people involved in the case are discussing what to do next.

On the side of the Songlin Villa area, Lao Song from the police station is still staring, and he can act at any time.

Huang Jianmin pondered for a moment: "The case has been handled to this extent, and what we can do is actually almost enough."

After listening to Huang Jianmin's words, everyone nodded, and they also understood what Huang Jianmin meant.

The nature of the case has been clarified, and the perpetrators within the jurisdiction have been apprehended.

The excavation of the remaining cases involves cross-provincial and even foreign countries, which is no longer led by a small police station.

"Turn it in?"

Lao Luo took out a cigarette and prepared to light one.

Lu Chuan took out his Huazi and threw it directly to Lao Luo: "Brother Luo, smoke this."

Lao Luo subconsciously took it and gave Lu Chuan a wrinkled smile back.

The two days of squatting have given the people of the Huaguang Street Police Station a deeper understanding of the wealthy.
