Chapter 550 - 550 504 Starting with a bang

550: Chapter 504 Starting with a bang 550: Chapter 504 Starting with a bang Jiang Yuan paced gently on the bridge boardwalk, pondering how to proceed with the investigation.

This time, the investigation work was quite different from the past.

The inspection had to be meticulous, or else some might slip through the net.

But with such a vast area to cover, being too thorough could delay the opportunity for action.

News of Huang Li Drug Trafficking Gang’s capture probably hadn’t spread widely yet, but it would eventually, and by then, the suspects might flee, rendering the evidence collected useless.

Since there were six floors in total, plus a basement, all of which were key areas to investigate, Changyang City Bureau’s regular bridge boards were not enough, and additional ones had to be urgently purchased.

The acrylic bridge boards under Jiang Yuan’s feet were the most suitable—made of a type of plastic often used for fish tanks, they were transparent and sturdy enough to support someone weighing over 200 pounds with equipment or carrying a body without breaking.

The advantage of their transparency was convenient for someone like Jiang Yuan, who reconstructed crime scenes or analyzed blood and other forensic work.

Of course, acrylic bridge boards were also the most expensive.

Changyang City Bureau used to buy a few each year and had some in stock, which had depleted due to various reasons.

Although they had urgently purchased more, to control costs, only the sixth floor was equipped with transparent bridge boards; the ones downstairs were metallic, and whatever they covered, they covered.

Walking on such bridge boards, Jiang Yuan continuously contemplated the investigation plan.

Huang Li’s office was the centerpiece of the investigation, but it spanned over 200 square meters, filled with a massive office desk, sofas, chairs, a wine cabinet, file cabinets, and a safe.

Based on surface area, the workload was overwhelming.

Moreover, this was the last office where the Huang Li Drug Trafficking Gang held out.

They had persisted in the room for a short time, burning some documents, flushing away some drugs, and even attempting to start a fire, which was extinguished, leaving just a wall’s curtains burned.

Thus, to describe the office as having been through the wars was quite fitting.

On the other hand, the office also received significant attention from the Changyang City Criminal Science Center.

The staffing of the Changyang City Criminal Science Center was on par with the Criminal Police Brigade, with much of its manpower concentrated in this main building, and most of that on the sixth floor.

Therefore, the scene on the sixth floor had already been scrutinized once.

A second inspection that had to unearth decisive evidence was an almost impossible task.

However…

Jiang Yuan thought for a moment and realized that, if there was any advantage to a second inspection, it was that there was no compulsory mission.

A first inspection followed a set of standards, collecting every necessary fingerprint, biological material, and photo without fail.

These were not only the foundational resources for the detectives to solve the case but also essential for subsequent investigations or corrections, and eventually for prosecution.

Hence, any on-scene investigator or forensic doctor followed a set of objectives and standards during an investigation.

But for a second inspection, there wasn’t much to say—if new evidence was discovered, it was credited to the investigator’s ability; if nothing was found, it was considered normal.

For Jiang Yuan, this meant he didn’t have to methodically collect fingerprints, footprints, bloodstains, and other evidence.

First, he would observe, and if he deemed it unnecessary, he could choose not to collect fingerprints or footprints—this step could save a significant amount of time, which was often the most time-consuming for investigators.

As for how to decide what was necessary or not, that required high expertise.

Theoretically, different footprints and fingerprints had distinct characteristics, but it was too difficult for ordinary people to remember, and even with training, if one was not sensitive enough to the relevant information, it might still be ineffective.

In Jiang Yuan’s experience, a skill level of Level 4 or above was relatively suitable.

For instance, he had recently advanced to Level 5 in footprints analysis, which allowed him some leeway.

Of course, if he had used it yesterday, Level 6 effectiveness would arguably have been even more advantageous.

Regardless, once he had established a plan, Jiang Yuan silently set to work.

No matter how great the design and thinking, without practical work, it was useless.

It’s like in American TV shows or Hollywood movies, where among the main character group, there’s always a silent but highly skilled tech geek, who often happens to be Asian, and then you see the protagonist, though ignorant, still dominating the game effortlessly…

The real world is clearly not this fantastic.

In reality, a criminal technician with decisive ability would actually become the leader, much like the eight tigers of the Ministry’s Criminal Investigation Department, each usually an expert in their field, taking command during cases and directing local detectives on investigations.

Jiang Yuan first reviewed the fingerprints and footprints collected by other personnel.

Thanks to these, the drug enforcement team had already arrested over a dozen individuals who had slipped through.

Most were core members of the Huang Li Drug Trafficking Gang.

If not a core member, one could not even enter this six-story building.

Jiang Yuan sorted out some characteristics of the fingerprints, committed them to detailed memory, and then roamed around Huang Li’s lavish office with an inspection lamp in hand.

He carried a multi-light source, lithium battery-powered, multi-color temperature inspection lamp—in simple terms, a lamp that could emit various colors.

He also had a large footprint inspection lamp, similar in purpose to the fingerprint lamp, but thicker and heavier than a fingerprint lamp or high-intensity flashlight.

The advantage was that the comprehensive light source revealed more fingerprints and footprints, with better effect.

Mu Zhiyang, who was already close to dozing off, hurried over to help carry the footprint lamp.
