Diary of a Criminal Investigator-Chapter 278: Survival After the Ordeal

Bringing Wang Guojun along was the right decision.

This guy chose a place that wasn’t the house left by Erpi’s grandfather.

Instead, it was the house left by Erpi’s great-grandfather, right behind the fire station, just a wall apart, and uninhabited.

There was only one path leading to the house, and when Wang Guojun left, he set up three tripwires using transparent nylon strings.

If someone touched it, the people inside the room would know.

If you didn’t know this beforehand, you might accidentally trigger it.

After all, by eight o’clock in Haizhou, it was already dark.

To avoid alerting them, they couldn’t turn on the lights during the capture.

Wang Guojun certainly made amends for his past mistakes.

As for Liu Bai, no one understood better than him the concept of a brush with death.

When Erpi looped the rope around his neck, he thought he was done for.

Even when the other party removed the rope, Liu Bai still felt enveloped by the shadow of death.

It was just a matter of living ten more minutes, then death would still come.

That feeling was like there was always a rope around his neck, slowly tightening.

It was precisely this sensation that made Liu Bai incredibly excited when he saw the armed police breaking through the window.

In the past, when he watched news about earthquakes or fires, hearing how rescued people were so excited to see soldiers in camouflage, he didn’t quite understand.

But now, he understood.

It was a second chance at life.

Two and a half days.

From the moment they received the call about Liu Bai’s disappearance to the capture of all criminal suspects and the successful rescue of Liu Bai, it only took two and a half days.

At this moment, Liu Bai’s concert is in progress.

Lu Chuan and Forensic Doctor Shen were sitting in the front row.

Speaking of which, the two of them could be considered fans of Liu Bai.

Yesterday, Liu Bai’s agent, Xu Zhe, sent dozens of concert tickets to the Criminal Investigation Team.

And they were all excellent front-row seats.

As a result, many from the Criminal Investigation Team came to watch the concert.

Especially the younger people, almost all of them were there.

On stage, Liu Bai was flamboyant and confident, showing no signs of having been kidnapped yesterday.

"Hello, music fans of Haizhou."

After the opening song, Liu Bai, holding a guitar, said, "This time coming to Haizhou is the most valuable experience of my life."

"It made me feel the enthusiasm of the Haizhou fans and the dedication of the Haizhou police."

"Thank you all, here’s a song ’Mighty Forest’ for you!"

The news of Liu Bai’s kidnapping had been kept confidential.

Otherwise, if a public figure like him were kidnapped, it would have become explosive news nationwide.

Fortunately, the Haizhou Criminal Investigation Team was indeed very capable.

Early the next morning.

"Lu Chuan, Captain Qin wants you to come over."

"Sure."

Lu Chuan could now be considered a regular in Qin Yong’s office,

being called over every few days.

And, unlike others when entering Qin Yong’s office,

whether it was Ren Qiang, Liu Guodong, or Sun Jun, going into Qin Yong’s office was either to get scolded or to be assigned work.

In general, it was rarely for anything good.

But not for Lu Chuan; when he went to Qin Yong’s office, it was mostly to be praised.

"Lu, you’re here. Have a seat."

"You did a great job in Liu Bai’s case. Director Wang called this morning to say your commendation notice has come through."

Of course, this commendation notice wasn’t just for Lu Chuan alone.

It also included Chen Feng, the director of the Democracy Road police station, and people like Liu Guodong.

Lu Chuan was named first.

And the title of the commendation notice was about the commendation for Comrade Lu Chuan of the Criminal Investigation Team and others.

"Thank you, Captain Qin."

The leaders didn’t know what role he played in the case or what he did.

Receiving this commendation was undoubtedly due to Qin Yong’s efforts.

Was this why he called him over?

"Captain Qin, do you have anything else to arrange?"

"Ah?"

"Haha, nothing much, just wanted to know, yesterday you and Guodong mentioned you have some research on voiceprints?"

"Oh, that, well, I wouldn’t say research, just picked up some things when I had free time."

"Captain Qin, is there something you need?"

"Well, not really, but our team has some funds, and I’m thinking whether we should purchase some voiceprint identification equipment."

"If you can use it, then we’ll buy; if not, it’s just a waste."

Buying equipment is certainly a good thing.

Lu Chuan quickly nodded: "I can use it, it’s just that voiceprint identification analysis equipment is quite expensive, and we..."

"No worries, the donation from your family still has plenty left, buying the equipment isn’t a problem."

"Moreover, with this, our Criminal Investigation Team would be setting up the first voiceprint identification laboratory in the province, wouldn’t we?"

This...

Lu Chuan hadn’t considered that.

But, as Qin Yong said, it could be true.

"I suppose... it counts?"

"What do you mean by ’suppose,’ it definitely does, haha, alright, nothing else, you can go back and wait for the news."

After Lu Chuan left, Qin Yong hurried back to his desk.

"Director Song, this is Qin Yong."

"We are now officially applying to the bureau, planning to establish the first voiceprint identification laboratory in the province!"

"Equipment? The bureau doesn’t need to pay; we’ll buy it ourselves."

"Technician? No need, no need, our team’s Lu Chuan has done research in this area, and for Liu Bai’s case, his analysis of the phone recording was very useful, right, right, right!"

"Great, Director Song, once it’s set up, please come over for inspection!"

After hanging up, Qin Yong hummed with excitement.

The first voiceprint identification laboratory in the province, he knew exactly what that meant.

Why did Wang Kai get promoted back then? Wasn’t it because he set up a DNA analysis lab in crime scene investigation?

At that time, the technical identification center already had DNA identification, but the Criminal Investigation Team’s was for their own use.

And a voiceprint identification laboratory, none existed in the province.

Of course, one aspect is that the application of voiceprint identification and analysis is mainly in small cases like phone fraud.

In major cases, it’s rare to identify a criminal through voice.

But rare doesn’t mean it never happens.

Five years ago, a murder case occurred in the neighboring Tianzhou City.

Because it was at night, nothing was captured on surveillance cameras, only the culprit’s voice.

However, at that time, the province couldn’t perform voiceprint identification and analysis and had to seek help from a neighboring province.

Eventually, the case was solved, but it was embarrassing. 𝘧𝓇ℯℯ𝑤ℯ𝘣𝓃ℴ𝓋𝑒𝑙.𝑐𝘰𝑚

But there was no other choice; voiceprint identification and analysis isn’t something you can do just by looking at spectrogram images.

It requires professionals.

And now, the Haizhou Criminal Investigation Team has such a professional.

"Lucky star, lucky star, hahaha."

Qin Yong felt that since Lu Chuan joined the team, it seemed like solving cases had become effortless.

In the past year, quite a few major cases have occurred, some very tricky ones.

Without going into distant cases, just this Liu Bai kidnapping case.

If Liu Bai had really died in Haizhou, what a terrible impact that would have had?

Qin Yong hummed a tune, crossing his legs, genuinely feeling that life was good.
