Should I use the backend?” Wang Bo quickly asked.

Jiang Yuan replied, “I want to compare fingerprints on the computer.”

He had just marked the feature points on his phone once but hadn’t found a match.

After refreshing the screen and taking another picture, he was ready to use the computer for comparison.

After all, the size of the screen is very important.

Viewing fingerprints on a phone, many details are not very clear.

Wang Bo hastily agreed and led Jiang Yuan out of the color steel house.

The two of them walked slowly across the acrylic footbridge.

After a while, Wang Bo couldn’t help but whisper, “Jiang, why would the killer jump from the second floor?”

Jiang Yuan, hearing the strong curiosity in Wang Bo’s tone, gave him a look and suggested, “How about we wait until we find the killer and then ask him?”

“Is that…

the only way to find out?” Wang Bo felt a tickle of disappointment.

Is a case solved by simply asking questions?

Jiang Yuan could sense Wang Bo’s inherent stubbornness and smiled, asking, “Do you really want to guess?”

Wang Bo got excited, “What do you think is the reason?”

“I don’t feel like guessing.

I’m not interested,” Jiang Yuan admitted frankly.

“I like to do the technical work.

For me, finding footprints, matching fingerprints, or finding DNA is more interesting.”

Wang Bo exclaimed, “No way, even though we work in forensics, just like that, just like that…”

He repeated himself twice, which was most likely a polite way of saying: That’s it?

Jiang Yuan said, “Director Liu Jinghui from the provincial department probably fits your criteria better.

He likes to play the detective…”

“He’s purely guessing…

I mean, purely reasoning, that’s not for me either,” Wang Bo said and then, feeling a bit embarrassed, hurriedly added, “I’m not talking about work, nor am I saying his methods are bad, it’s just a matter of personal interest.”

Jiang Yuan understood.

People are diverse, and the more cases one deals with, the more one realizes this.

Some people like power, some like money, some like women, others enjoy ‘barking at the sun,’ and then there are those who enjoy playing detective or, like Wang Bo, those who like both technology and deduction.

With a major breakthrough in the case, Wang Bo’s view of Jiang Yuan changed.

As they spoke, Wang Bo gradually became more open and couldn’t help but say, “I feel that just using technology to solve cases has its limitations.”

Jiang Yuan agreed, “Of course it does.”

Wang Bo continued, “I mean, if it wasn’t for your determination of the murderer’s movements, or if he had jumped onto clean cement instead of soil, leaving no footprints, or if he had swept away any footprints, wouldn’t our case come to a halt?

Just the thought of that is daunting.”

Jiang Yuan shook his head, “It would become more difficult, but not unsolvable.”

“Are there other ways to solve it?”

“Of course.

The most direct approach is to sweep the entire room.

Collect all the footprints, then compare them with the footprints’ movements outside,” he replied.

“That sounds like a lot of work,” Wang Bo remarked.

Glancing at Wang Bo, Jiang Yuan said, “So many people are sitting idle, so why worry about workload?

In homicide cases, as long as there is a plan, the manpower expense is the squad leader’s concern.”

“Ah…

I see…” Wang Bo had to admit that this approach might indeed flush out the killer.

Despite the multitude of footprints at the construction site, the number of people who would enter the cashier’s office is limited – likely around ten sets of footprints or so.

Identifying these people’s footprints, drawing up diagrams, and tracing their movements, it would certainly reduce the suspect pool, differentiating those with lower suspicion from the ones with higher suspicion.

Jiang Yuan continued, “If we track the footprints backward, we might discover a set of footprints that begin right beneath the cashier’s window.

In that case, there’s a decent chance that fingerprints at the window could be found.”

Wang Bo nodded subconsciously.

Indeed, using this method, as long as they were meticulous enough, the discovery of footprints beneath the cashier’s window would definitely raise suspicions.

“If the footprints inside the room were organized properly, it’s also possible to trace the murderer’s movements.

However, uncovering the murderer’s fingerprints will take some effort,” Jiang Yuan was summarizing to himself.

Wang Bo strongly agreed, “The method of mixing magnetic powder with ink powder is probably not known by many people.”

“Looking on the bright side, if the killer had worn gloves, it would likewise leave no fingerprints.”

“Right, so what do we do then?”

“That’s why it’s always good to have a few more technical skills,” Jiang Yuan paused, pondering, and then said, “If we could confirm the footprints, trying to find the killer’s means of transportation could give us a breakthrough.”

Wang Bo was taken aback, “Yeah, we couldn’t find the means of transportation before because we had no leads, but now that we have footprints, we can start looking for the transport.

Should we report this to the leadership?”

“You make the call to report it.” With new clues, it was only right to follow up on the investigation.

Of course, what Jiang Yuan was more concerned about at the moment was the fingerprints.

However, as he had just said, with so many people involved, following the trail of the means of transportation and gathering more clues and evidence could never be a bad thing.

Upon reaching the entrance of the construction site, Jiang Yuan gained access to a computer and connected to the internal network to start searching for fingerprints himself.

Around the same time, more detectives and technicians began to spring into action.

Yu Wenshu was indeed very interested in the new clues and direction of the investigation.

It wasn’t guaranteed that the fingerprint would yield results, so he certainly was willing to broaden the scope of the investigation.

The walkie-talkie left inside the survey vehicle occasionally crackled to life.

At this moment, both inside and outside the construction site were bustling with activity.

Inside were technicians busy preserving footprints; outside were detectives scurrying to locate the transportation used by the killer.

Not far from the construction site, there was a gradually bustling market and shops.

Places not covered by police surveillance cameras, those avoided by the perpetrator, might just be under the watch of someone’s video feed, but that would require a door-to-door inquiry.

Jiang Yuan pulled up the fingerprint and carefully identified its characteristics, painstakingly comparing it…

“Hmm, it must be because the screen is too small.” It wasn’t long before Jiang Yuan successfully matched the fingerprint.

As expected, the suspect Qi Penghu was a fugitive with a criminal record for theft and robbery, and he had also been involved in a Black Society organization case…

The photo of Qi Penghu showed him with short hair, a short nose, a big mouth, rough skin, and a scar at the corner of his eye…

He had a fierce appearance that made it tough for him to find ordinary work.

Having submitted the information in the system’s backend, Jiang Yuan stretched and took the opportunity to look around.

The construction site, known as the Binhu Spring Greening Landscape Project, was located in the old district of Changyang City.

Nearby were bustling areas frequented by people passing by to shop or local residents out for a stroll, all of whom curiously watched the police officers and patrol cars coming and going.

Some, bold and idle, even stood not far away to spectate.

Turning his head, Jiang Yuan saw a man with distinctive features, around thirty, with short hair, a short nose, a big mouth, rough skin, and a scar at the corner of his eye…

Jiang Yuan glanced down again, silently looking at the photo on the laptop, regretting that he hadn’t brought Mu Zhiyang with him because of the rushed nature of this visit…
