Chapter 553 - 553 506 Direction

553: Chapter 506: Direction 553: Chapter 506: Direction The Huang Li Drug Trafficking Gang’s basement renovation plan was extremely immense and luxurious.

With a surface area of 2000 square meters and a height of about ten meters, it was equivalent to an underground factory.

The space they currently used for production was less than one-tenth of the total area.

The entire underground space still had great potential for expansion.

Jiang Yuan, following the production line, quickly found several more fingerprints and slowly accumulated some insights.

More precisely, it was a clash between the habits of the Criminal Science Center’s crime scene investigators and trace evidence collectors, and the drug trafficking gang members.

The crime scene investigators and trace evidence collectors of the Criminal Science Center used the thought patterns of normal people to analyze and conduct their surveys.

But you wouldn’t guess the mindset of the drug dealers—who else would truly leave fingerprints on a wall five meters high?

If you ask why?

The answer is they were high on drugs.

Besides that, fingerprints and other traces existed in some bizarre places.

Like inside corners of sofas that normal people would never look at, or the top of the back of a cabinet.

Jiang Yuan even found a trace on the inside of a refrigerator that was clearly made by a licked tongue—the tongue had melted the ice, and the saliva had re-frozen, leaving behind a print resembling the pattern of a tongue coating.

Jiang Yuan wasn’t too concerned about what circumstances it was made under, why it was there—he just needed to collect the DNA.

A trace evidence collector from the Criminal Science Center silently followed behind Jiang Yuan, standing even further away than Lu Tongda, but always behind him like a half-wild pet dog drooling.

Mu Zhiyang glanced back warily, his eyes a bit fierce.

He already had Lu Tongda with him.

Now, if he went out, the car would be just right with one more suspect, but any more would indeed be too crowded.

The trace evidence collector was about 30 years old, facing Mu Zhiyang with a mature, social smile and continued to follow Jiang Yuan’s steps, taking notes from time to time.

Mu Zhiyang looked back at Jiang Yuan, who was in a state of hyper-concentration, so Mu Zhiyang kept his mouth shut.

“There’s another one here,” Jiang Yuan said, shining the strong flashlight upward, pointing at a fake window in the basement.

This fake window was even more outrageous, about six or seven meters high, with a ring of bricks, unusable for entry or exit, at best it served a decorative purpose.

Lu Tongda immediately brought over a ladder, saying, “Who would climb up there, and what would be their purpose?

To hide something?”

“If you stack three people vertically, you could just reach this fake window, adding a bit of challenge,” Mu Zhiyang offered an answer that fit the situation.

Lu Tongda clicked his tongue twice, somehow finding it sensible, and as he climbed up, said, “But, Captain Mu, how did you think of stacking three people up?”

“Didn’t you climb walls when you were in school?” Mu Zhiyang supported the ladder and casually responded.

Lu Tongda thought back for a moment, “We usually just went through holes.

Isn’t climbing walls quite dangerous?”

“Usually you would go through holes, but what if the hole was discovered or blocked?

Climbing is actually the safest, relying on yourself and your brothers, not on luck,” Mu Zhiyang sounded somewhat proud.

Lu Tongda said, “If I weren’t up here, I’d be giving you a respectful salute.”

“It’s nothing.

When we were at the police academy…

cough cough, right, you graduated from Shannan Police Academy, didn’t you?”

“Yeah, the stone on the east side, right?”

Mu Zhiyang laughed, “It seems the good traditions are still being upheld, huh?

How did you end up becoming a traffic cop.”

“Back then I thought the motorcycle brigade was pretty impressive, and they required a height of 180cm.

I’m 180cm tall, so there was no reason not to join,” Lu Tongda said quite seriously when he mentioned being 180cm tall.

Mu Zhiyang, seeing him in position, reminded, “Be careful collecting fingerprints, don’t fall.

Also, Captain Jiang is much taller than you.”

Lu Tongda let out a laugh, “That only makes Captain Jiang stand out more.”

Mu Zhiyang gave a dark look, thinking, this kid is saddled up and polishing the saddle.

The fingerprints were collected and logged, indeed matching one more person.

“Dead,” half of the new people Jiang Yuan had found were dead.

Nothing strange about it; those who pointlessly stacked themselves three high in a factory would eventually find their moment of death.

The trio continued their inspection, a rather tedious affair.

The crime scene investigators behind the three of them observed with great interest for a while.

Time, like snow, always melts into water quickly when you want to play with it, and refuses to thaw when you find it bothersome.

The temporary skill +1 for 405 minutes seemed unlikely to last until the end of the basement’s inspection, and Jiang Yuan did not quicken his pace even after this thought occurred to him.

When it comes to crime scene investigation, the more thorough, the better.

It’s advisable to inspect as much as possible.

With that in mind, Jiang Yuan turned his attention to several cardboard boxes in the corner.

“Did you guys take samples from this?” Jiang Yuan walked around the boxes twice before bringing over the footprint light.

“We took a few…” the summoned crime scene investigator hurried over and cautiously asked, “Do you think there’s a problem?”

“Boxes from outside in a drug manufacturing plant aren’t likely to be employees’ parcels,” Jiang Yuan half-joked before laying the boxes flat and starting a meticulous search.

Normal crime scene procedure focuses on the key points, like walls and floors.

There could be evidence everywhere, but it’s not feasible to swipe everything.

Back when Jiang Yuan worked on secondary investigations, it took almost half a day for two people to just cover one bathroom.

The previous investigators didn’t prioritize the boxes, which also had to do with the information they received.

After several discussions with Liu Jinghui, Jiang Yuan believed that Huang Li’s drug trafficking gang had a close connection with Lao Gui’s drug gang.

Therefore, considering what drug gangs typically desire, their relation must be material rather than spiritual.

These cardboard boxes offered a crucial clue to Jiang Yuan.

The source of raw materials for Huang Li’s drug trafficking gang had always been a mystery; these boxes might provide some answers.

He photographed them, dusted for prints, took samples, and then photographed again…

Just like before, Jiang Yuan directly uploaded the results to the system for comparison.

The work he was doing, though seemingly simple, was actually a process others found hard to replicate.

Just comparing fingerprints alone would take a regular crime scene investigator ten to twenty times, or even a hundred times longer.

Simple fingerprints that can be matched directly are straightforward, but proving that a non-match is due to the absence in the system rather than one’s own technical limitations is much more difficult.

Therefore, at the crime scene, when crime scene investigators take fingerprints, they take them without running to compare them immediately.

It was only someone of Jiang Yuan’s high skill level who could adopt such an approach.

And the results turned out to be surprisingly good.

“Secure the scene.

I’m going to make a call,” said Jiang Yuan as he took out his phone and dialed Liu Jinghui once more.

The expressions of everyone there became solemn.

The difference between sending a message and making a call was quite clear.

Liu Jinghui, cheery as ever, answered the call, “Have you finally decided to give me a call?”

“I’ve matched a Qinghe Jiayuan Pharmaceuticals employee, to be precise, a parking lot security guard from Jiayuan Pharmaceuticals,” Jiang Yuan said, recalling the case he worked on before where almost all of Jiayuan Pharmaceutical’s parking lot guards were rounded up.

On one hand, these guards were getting parking subsidies, and on the other hand, they acted as enforcers for the upper management of Jiayuan.

Because they ran afoul of Jiang Yuan, they were almost entirely apprehended.

However, as though they had agreed upon it, none of them confessed to drug trafficking, mostly driven by self-interest…

Liu Jinghui gasped, “Jianyuan Pharmaceutical?”

“Yeah.”

“Well, well.

If it’s a pharmaceutical company…

If they wanted to produce something, it would be all too easy.

What’s the reliability of the evidence?”

Jiang Yuan then briefly described the scene.

Liu Jinghui let out a heavy sound of affirmation and said, “I’ll go report this.”

The task was beyond his capabilities.

Jiayuan Company was massive and the situation within the plant was complex; it wasn’t a matter of just making a phone call to summon people anymore.

Moreover, if they planned to make arrests, they could be facing off against an entire drug trafficking organization, which naturally required further planning.
