175: Chapter 167 Real Case_2 175: Chapter 167 Real Case_2 Dazzling,

Chaos that captivates the eye,

Out of sight, out of mind,

Worrying is pointless

After such operations, Jiang Yuan re-marked the thirteen reference points.

Jiang Yuandao said, “The locations we just marked are the usual reference points, and since there’s no match, it means that the previous crime scene technician did a decent job.

The suspect didn’t leave behind a very clear complete fingerprint for us to match.

No worries, let’s try again.”

Similar to the previous steps, Jiang Yuan threw the marked fingerprint into the fingerprint database for comparison.

Soon, the data returned from the fingerprint database was again twenty fingerprints in a row.

“We still need to compare them side by side, right?” This time, Jiang Yuan asked Cao Keyang, showing politeness.

Cao Keyang nodded obediently and concentrated on watching the projector.

This time, he felt like he was ready.

At the three-quarters mark on the left side of the projector screen, two fingerprints were listed.

With a light movement of the mouse, Jiang Yuan drew a small circle on the left, and then another on the right, and said, “Discarded, right?

Same idea as before.”

“The second one is discarded too.”

“Same, huh.”

“For the ones below, we don’t need to circle each one.”

As he spoke, Jiang Yuan quickly pushed the fingerprints through.

He tapped the space bar on the keyboard, and a new fingerprint would appear on the screen, replacing the old one.

Since Jiang Yuan was no longer circling, he would just glance at each one, say “No,” and then hit the space bar again to bring up a new fingerprint.

Cao Keyang initially stared intently but quickly fell back into the state he was in earlier:

Eyes

Chaos

Eyes

Worry

For a moment, Cao Keyang almost thought he was scrolling through short videos.

A screen full of internet celebrity ladies, and they all looked quite similar.

Look at one, swipe it away.

Look at another, swipe it away.

In a daze, half an hour passed by.

At that time, Jiang Yuan also re-marked the fourth set of characteristic points and said, “Actually, the characteristic points we just marked weren’t very necessary; it was just to show everyone.”

“In the future, once you get practiced and proficient, you can skip the marking pattern we just did, because the characteristic points we marked just now overlap with the previous ones.

To just try it out this way isn’t very efficient.”

“A more efficient method is actually to define a small area and then mark as many characteristic points as possible.

This way, the accuracy of the fingerprints returned will also improve.

Of course, this makes it a bit more difficult.”

“Same method as before…”

As Jiang Yuan spoke, the sound of tapping the space bar resonated in the lecture hall.

Not just Cao Keyang, but most technicians in the lecture hall felt somewhat numb.

Jiang Yuan was doing it too quickly.

Everyone was finding it hard to keep up.

Yet they hadn’t considered if Jiang Yuan were to match their pace while also explaining the fingerprint process, a complicated fingerprint could take days to analyze.

A training session only lasts a total of four hours over two periods.

An older crime scene technician cleared his throat, seemingly intending to speak.

The crowd held their breath and watched, waiting for this brave soul to raise a voice on behalf of them all.

After all, it was training within a disciplined force, and if you upset the teacher, it was very easy to get into trouble.

The tapping sound suddenly stopped.

For almost half a minute, Jiang Yuan didn’t speak or make any moves.

Such silence in the lecture hall made Cao Keyang, who had almost given up, involuntarily lift his head and look toward the projection screen.

On the projection screen, there were still two fingerprints.

The original fingerprint on the left, marked as a difficult one, was like a lady wearing a bodycon dress, looking as if it barely covered her, yet nothing was revealed.

The fingerprint from the database on the right was plain and ordinary, like a frosty ‘boss lady’ in a professional suit, her gaze sharp, her demeanor rejecting any advances, with not a single flaw to be found…

“It’s a match, right,” Jiang Yuan added another sentence behind, as if it was part of the lesson.

Cao Keyang was dumbfounded.

What did he mean by it’s a match?

He looked at the original fingerprint on the left, then at the database fingerprint on the right.

They looked quite similar.

Almost identical.

No flaws.

Indisputable.

Then…

was he forced to conclude they were from the same person?

In the end, were the bodycon beauty and the frosty ‘boss lady’ one and the same?

Cao Keyang was flabbergasted.

And it wasn’t just Cao Keyang, half of the police officers undergoing training were in a state of shock.

At this point, Jiang Yuan started to competently draft an “identification of sameness” forensic report and applied for a review.

In a room of over forty people, everyone just watched Jiang Yuan fill out the form.

Filling out the form—that part, everyone understood.

“Wait a moment for the review on this end, I’ll find a phone number for the jurisdiction over here,” said Jiang Yuan, then he added to the trainees, “Sorry for the delay, everyone.

It’ll just be two minutes.

After all, we’ve locked in a suspect, so I should make the call as a courtesy.”

“No problem, no problem,” a group of police officers wave their hands restlessly while sitting and standing.

Jiang Yuan then switched back to the case details, found the contact information for the local police station, and started to laugh, “It’s from Miao He County, I’ve spoken to them on the phone before, please hold on.”

Jiang Yuan had matched prints from a cold case homicide in Miao He County during a provincial fingerprint operation and had kept the phone number for the captain of the Miaohexian Criminal Police Brigade.

When Jiang Yuan made the call, the cheerful voice of Miao River County’s Criminal Police Brigade captain soon came through, “Doctor Jiang, what’s the occasion for you calling me?

Is it good news?”

“I’ve just matched a print to a routine case, a robbery from over six years ago…

Yes, the detailed information will be sent to you via the internal network.

Correct, correct, oh…

the review has passed…

you’re welcome, you’re welcome.”

Jiang Yuan sat at the lecturer’s seat, in a spot with good reception, and almost the entire conversation from their phones was heard by everyone present.

The technicians in the room looked bewildered.

The captain of the Miao River County Criminal Police Brigade has such a good temper?

Can someone with such a good temper really be the captain of a Criminal Police Brigade?

Also, what just happened?

In the strange quiet, Jiang Yuan completed the steps for sending information via the internal network.

“All right, the review has also passed, so this robbery cold case from six years ago now has a new key clue.

Next, it’s up to Miao He County to locate and arrest the suspect.

As for us, we’ve completed our work of comparing the fingerprints for the case just now.”

Jiang Yuan closed the web pages he had opened, finishing up the last of the tidy-up work.

“Let’s find another typical fingerprint and repeat the technique we just tried, to see if it works,” Jiang Yuan began searching for another fingerprint.

The guy who had just been clearing his throat couldn’t hold back anymore, he stood up with a “huff,” but what he wanted to say completely changed, “Just now, were we working on a real case?”

“Yes,” Jiang Yuan answered, adding, “That’s why the lecture is on practical application.

That…

as for the content I shared, can you get used to my teaching style?”

“We can, we can, it’s just, no, it’s not…

didn’t you, no, didn’t you just solve a robbery case?” The throat-clearing guy seemed unable to come to terms with what had just happened.

Soon, the small lecture hall was abuzz with chatter.

Someone even sent a clandestine message: Bro, come see a master at work.
