There is a direction for solving the case, and the police never lack execution ability.
In less than an hour, the cash and envelope were handed over to Lu Chuan.
"I went back to the detachment. There is no fingerprint extraction equipment here."
Fingerprints on cash and envelopes are more convenient to extract with a variable frequency laser scanner, and can also be extracted well with a special ultraviolet camera.
The Huaguang Street Police Station does not have such a thing.
In the past month, the Criminal Investigation Detachment has changed from top to bottom.
The 100 million specially donated by the powerful Qiangsheng Group was already in place the day after Lu Jianguo spoke.
Qin Yong had never seen so much money before. You know, this was specially donated to the Criminal Investigation Detachment.
As long as the detachment team makes a unified decision and reports it to the city bureau for approval, the bonus is paid, and no one can say anything.
Of course, it is impossible to issue bonuses. The Public Security Bureau often accepts donations and has relevant management regulations.
For more than a month, Qin Yong has really experienced the pleasure of spending money.
Seven dilapidated old police cars, with the exception of their horns blaring everywhere, went directly to the scrapping process.
According to regulations, these cars can actually be scrapped after being used for more than eight years and with a cumulative mileage of 200,000 kilometers.
However, due to financial constraints, the service was overdue for more than five years.
This time, replace them all.
The cafeteria has been completely renovated, and the shabby tables and chairs in the office have to be replaced.
The current survey office has a large share in it.
Mainly the update of experimental equipment.
For example, infrared and ultraviolet digital cameras, this equipment can directly extract fingerprint traces on smooth non-permeable and semi-impermeable object surfaces.
For example, fingerprints on the surface of glass, aluminum alloy or ceramics.
Another example is the full-spectrum on-site forensic instrument. This instrument has a good effect on displaying fingerprints on rough surfaces such as leather and banknotes, and is not prone to smearing.
In addition, this time the on-site investigation laboratory also added the most advanced on-site investigation equipment such as portable multi-band light sources, targeted biological trace detection instruments, ultra-wide spectrum on-site trace evidence search cameras, laser evidence detectors, etc.
In addition to these, the current investigation office is building a trace evidence laboratory.
"I heard from the leader that there is a case over there on Huaguang Street?"
Lu Chuan went back to the office first to show his face. Yang Sen and Liu Guodong were out, and only Lao Bai was there.
"I originally helped with fingerprint identification analysis for an electric vehicle theft case, but I didn't expect that another case would be revealed."
Lao Bai nodded, this kind of thing is very common.
General crime and homicide are not the same.
It is possible to kill just one person and get caught.
But ordinary petty theft is different. You may not be caught even if you do it ten times.
Therefore, most of the time, working on this kind of case is like a bastard laying an egg.
Once you have one, there are more to come.
"Master and the others are out?"
Lao Bai hummed: "There is a scene over there at the High-tech Zone Criminal Police Brigade that needs our support. Lao Liu and the others have gone over."
"A big case?"
Major and important cases may not always be reported to the criminal investigation detachment, and the criminal police brigade below is not just for free.
If all major and important cases in Haizhou City were handed over to the Criminal Investigation Detachment, the current manpower would be ten times more and they would not be able to handle it.
"Intentional injury. The couple fought. The woman chopped the man. He almost died. He is in the ICU."
"A couple fighting? Such a heavy blow?"
"Who knows, the neighbor called the police. If he hadn't gone there early, someone might have died."
Lu Chuan nodded, almost killing someone, the case was not a small one.
"Brother Bai, you're busy, I'll go to the laboratory, take a fingerprint, and analyze it."
"I will go directly to the Huaguang Street Police Station later."
"Okay," Lao Bai nodded with emotion: "Thanks to you, we have purchased a lot of new equipment this time.
"
"I don't know how to use many of them. Hey, I'm getting old."
Lu Chuan smiled and said, "The equipment is just that, just fiddle with it a few times and it'll be good."
"Okay, go ahead and do your work. I'll go read the instructions."
Detachment basement.
Lu Chuan quickly collected fingerprint information on the envelopes and cash notes.
But not one, but a dozen.
It is still quite difficult to handle.
An hour later, seventeen relatively clear fingerprints completed pre-processing and were successfully compared within the system.
The result was very good. Among the owners of these seventeen fingerprints were Zhang Baoku and Chen Wen.
The interrogation room of Huaguang Street Police Station.
"Chen Wen, this is the cash received from Zhang Baoku, as well as the fingerprints taken from the envelope containing the cash."
Lao Luo photographed an appraisal analysis report in front of Chen Wen.
"You think you did it flawlessly. Do you think you can pick it off without having direct contact with Zhang Baoku, without calling or transferring money?"
"How do you say this?"
At this moment, Chen Wen was sweating profusely.
"That money...maybe happened to be what I used..."
"You happen to have used it? Where's the envelope? You happened to have used the envelope containing the money?"
"me"
Chen Wen's expression changed drastically, and his mouth opened unconsciously as he wanted to quibble.
But as Lao Luo said, there were more than a dozen people’s fingerprints on the money. Chen Wen could explain it by saying that he happened to use it, but what about the envelope?
The envelope can't be something you happen to have used, right?
Chen Wen has dealt with the police a lot, and he knows when to pretend and when to hide.
"I...I will confess, Officer Luo, I will confess!"
Faced with irrefutable evidence, Chen Wen explained the whole story.
"What's in the box...is ivory!"
ivory?
"Are you reselling ivory?"
Chen Wen drooped his head: "No, no, I don't resell, I am the middleman, the transporter, I don't resell."
"Say! Tell me clearly, where did the things come from, why were they sent to the Pine Forest Villa area, and who is your last family? Tell them all clearly!"
"I said, I said..."
What happened is relatively simple.
Haizhou City is the processing area for the entire criminal chain.
"The Pine Forest Villa is responsible for continuing to process the ivory. I'm the courier, really."
"Some of the antiques and handicrafts in my shop are imported from Myanmar."
"The things are hidden inside and sent to me through logistics."
"I'll pack the things and hand them over to the next shop, and they'll be responsible for processing. I don't know what happens after that."
"How do you know these people?"
"I traveled to Myanmar last year... I met..."
The chain of the case is already relatively clear.
Haizhou City is a link in the entire chain and is responsible for processing the things sent by Chen Wen.
However, Chen Wen did not know the situation of the entire upstream and downstream industries.
"Huang Suo, are you going to arrest the people in the villa area?"
In the conference room, several people involved in the case were discussing what to do next.
Over at the Pine Forest Villa area, Lao Song and the others from the police station are still watching and can take action at any time.
Huang Jianmin pondered for a moment: "Now that the case has been solved to this extent, our firm can actually do almost everything."
After hearing Huang Jianmin's words, everyone nodded and understood what Huang Jianmin meant.
The nature of the case has been clarified, and the perpetrators within the jurisdiction have been arrested.
The remaining case excavation involves cross-province and even foreign countries, which is no longer something that a small police station can lead.
"Hand it in?"
Lao Luo took out his cigarettes 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 crumpled smile.
These two days of squatting gave the people at the Huaguang Street Police Station a deeper understanding of wealthy people.
