Diary of a Criminal Investigator

Chapter 71: The Missing Electric Scooter Owner


The reward for the Zhang Zixuan skin case has not yet been applied for.

Qin Yong is still striving for it.

It's not that there is no merit reward, it's just that Qin Yong wants to strive for more.

In the past few months, the performance of Haizhou City Criminal Investigation Team has been remarkable.

They have continuously solved several major cases, especially several recent murders, achieving significant results in a short time.

Not only that, but they also helped Tianzhou City Criminal Investigation Team solve a kidnapping case.

Although it was just a continuation of a skeletal case from sixteen years ago, the case itself was handled beautifully.

As the year-end approaches, looking across the province, Haizhou City Criminal Investigation Team ranks among the top in case-solving rates and major murder case investigations.

Today, there is hope of surpassing Tianzhou City Criminal Investigation Team in performance ranking.

And all of this is related to the Crime Scene Investigation office, or to be precise, Lu Chuan.

In recent cases solved by the Criminal Investigation Team, Lu Chuan has shown exceptional performance.

Many times, he could provide key evidence to assist in handling cases, even directly identifying suspects.

Of course, no case is solved by an individual alone.

It requires teamwork, and every participating detective is indispensable.

Take the confirmation of Zhang Zixuan's identity, for example.

The breast augmentation surgery scars found by Lu Chuan on the skin gave the action team a direction for investigation.

Without Lu Chuan's hint, confirming Zhang Zixuan's identity would have been uncertain.

If the deceased's identity couldn't be confirmed, how could the case be cracked later?

But the real clue discovery and information tracking were done by Wang Shuai.

The entire action team of officers worked overtime at the front lines for this.

Speaking of this aspect, both Lu Chuan's discovery and Wang Shuai's investigation were crucial.

Neither could be done without.

So, even though Lu Chuan's contribution was significant, in previous cases, he only received commendation as a reward.

One or two cases might be excusable, but four or five cases are hard to justify.

Qin Yong is thinking about whether he can strive for a third-class merit award.

It would be an acknowledgment of Lu Chuan's contributions during this period.

Of course, Lu Chuan doesn't know that Qin Yong is trying to win merits for him.

In the laboratory, he is conducting fingerprint identification analysis.

Since the Zhang Zixuan case, Lu Chuan has also been able to handle fingerprint identification analysis tasks from the Crime Scene Investigation office, and is now a main force.

And as Yang Sen put it, it's not only accurate, but also impressively fast.

Although Lu Chuan doesn't quite like Yang Sen's way of complimenting, it's an undeniable fact that he has become a fingerprint identification expert at the Crime Scene Investigation office.

This time, the request for support from the High-tech Zone involved a disappearance case.

Lu Chuan is now doing fingerprint identification analysis.

Compared to collecting fingerprints from skin, the fingerprints sent over from the High-tech Zone Criminal Investigation Team are relatively simple.

The fingerprint carrier was collected from an electric vehicle, a total of thirty-five prints.

The vast majority of the fingerprints were severely deformed, and several of them had more than one-third missing.

Each district and county Criminal Investigation Team in Haizhou actually has its own fingerprint identification detectives.

However, like the Criminal Investigation Team here, fingerprint identification detectives at the lower level are mostly part-time, and still frontline detectives part-timing.

So their capability is naturally limited.

For ordinary fingerprints, if the completeness is high and the ridge pattern is clear, they have no problem doing the identification.

But once the fingerprints are more deformed, or have larger missing parts, it becomes very challenging to ensure a good comparison.

In front of the computer screen, Lu Chuan is still using the built-in image processing software.

He continually adjusts the deformed fingerprints, marks and analyzes characteristic points, and calculates some data.

After several repetitions, in about a dozen minutes, a fingerprint is almost done.

Of course, Lu Chuan cannot be doing fingerprint analysis all the time; he has other work.

So these thirty-five fingerprints took Lu Chuan two afternoons to finish.

When the matching information of the last fingerprint showed success, Lu Chuan also breathed a sigh of relief.

"Master, all the fingerprints are done, and luck is on our side, all thirty-five fingerprints matched successfully."

Liu Guodong received the analysis report and nodded: "Not bad, these people's information is all in the database."

"Alright, take a break. I'll let the High-tech Zone people come over to get the report later."

This completion of work here means the work of the High-tech Zone Criminal Investigation Team is just beginning.

Yuan Shaokang, the captain of the High-tech Zone Criminal Investigation Team, and Ren Qiang, Liu Guodong are friends, all about the same age.

"It's done so quickly... all right all right... I'll send someone over to get it. One of these days, I'll treat your Crime Scene Investigation team to a meal!"

Yuan Shaokang and Liu Guodong have known each other for over twenty years, very familiar with each other.

"Alright, don't make empty promises to me, thirty-five fingerprints, a total of twenty-five people, and several are outside the province, you'll be busy."

As a district Criminal Investigation Team captain, Yuan Shaokang certainly wouldn't personally handle a disappearance case.

Actually, the reason this disappearance case attracted attention was mainly because the family of the missing person kept causing disturbances in Yuan Shaokang's office every few days.

It couldn't be helped, so Yuan Shaokang personally came to the Crime Scene Investigation office to request help.

This isn't to say that the High-tech Zone Criminal Investigation Team doesn't value disappearance cases.

The reality is that adult disappearance cases are not taken seriously by almost all police stations and Criminal Investigation Teams.

Unlike child disappearances, because children lack autonomy, as long as they are missing, it is usually abduction or other danger.

But adult disappearances are different.

Adults have the ability to act independently.

Disappearing may be to evade debt, to start a new life, or even to disappear into the mountains — there are many possibilities.

Ordinary people mostly consider disappearance a very serious matter, but in the eyes of police dealing with cases daily, disappearance is sometimes less important than a lost electric bike.

For instance, Lu Chuan once heard Liu Guodong mention a man suddenly stopped going to work, and the family couldn't contact him, fearing something happened and reported it to the police.

It turned out that six months later, he returned and claimed to have gone to Zhongnan Mountain for spiritual retreat.

Song Kun, 59 years old, one of the oldest detectives in the High-tech Zone Criminal Investigation Team, with extremely rich investigative experience.

The Gao Sheng disappearance case was under his watch.

In the afternoon, Song Kun received the fingerprint identification analysis report of the thirty-five fingerprints from Yuan Shaokang.

Song Kun knew that these were the subjects he needed to investigate next.

Twenty-five people...

In the office, Song Kun lit a cigarette, took a deep puff, exhaled a large smoke ring, which rose and mingled with other smoke rings in the office before dispersing.

As a seasoned detective, Song Kun does not even remember how many times he has conducted this kind of screening.

The Gao Sheng disappearance case isn't much different from ordinary disappearances.

It's simply that the person vanished suddenly, and no one knows where he went.

The only slightly unusual point is that Gao Sheng disappeared on his way home from the company.

At a location just five hundred meters from his home, he left behind his ride... an electric vehicle.
