Diary of a Criminal Investigator

Chen Tianbao is the janitor at the bank where the crime occurred.

During Song Mingguang’s investigation of all bank staff’s call records, Chen Tianbao’s call records were under suspicion.

You need to experimentally verify that Chen Tianbao’s DNA information and the DNA information from the short hair left by robber No. 1 are related by blood.

This discovery by Lu Chuan and his team is crucial.

"Should we make the arrest?"

When Lu Chuan made the call, Gao Xiang, the captain of Binzhou City’s Criminal Investigation Team, was with Li Donglin.

"Of course, arrest him, immediately apprehend Chen Tianbao!"

Li Donglin decided at once, to immediately arrest Chen Tianbao.

"Lu Chuan, leave the work in the lab to others for the arrest; you are needed in action."

Although there has been some progress in DNA identification and comparison, that doesn’t mean the subsequent work can stop; this is just one important clue, but may not be the only one.

Thus, related work should continue, but Lu Chuan’s participation in the arrest action is evidently more important.

After hanging up the phone, Lu Chuan left the DNA laboratory, changed into his clothes, and prepared to join the operation.

Li Donglin placed great importance on this action and called Wang Song, Luo Qiang, and Song Mingguang respectively, instructing all relevant members of the major crimes team to return.

Judging from the current clues, Chen Tianbao is definitely not a suspect; he was in the bank on the day of the incident.

Therefore, the arrest must be swift and stealthy, with quick interrogation to break down the opponent’s defenses.

By apprehending Chen Tianbao, three suspects can be locked down, enabling their quick arrest to prevent escape.

Half an hour later.

All members of the major crimes team had gathered.

"I will personally command this arrest mission. Lu Chuan and Luo Qiang, you two gear up for the arrest; everyone else, coordinate, understood?"

"Understood!"

Li Donglin did not involve Gao Xiang’s team from Binzhou City’s Criminal Investigation Team too much in this operation.

Compared to the officers in the Criminal Investigation Team, Li Donglin evidently trusted the major crimes team members more.

Especially Lu Chuan’s skills, having seen them in action several times, Li Donglin was already informed.

In crime scene investigation techniques, Lu Chuan was the undisputed lead within the major crimes team.

Additionally, in terms of solo combat ability, Lu Chuan was also undeniably first-class, whether in shooting, fighting, or tracking and reconnaissance, he was exceptional.

Among many criminal police officers Li Donglin has encountered, Lu Chuan absolutely ranked in the top tier.

Among the many members of the major crimes team, apart from slightly lacking experience, Lu Chuan is absolute number one in all other aspects.

A person’s energy is limited, and to master a particular area requires immense focus and dedication.

As the Director of the Provincial Criminal Investigation Department, Li Donglin has encountered many highly specialized talents.

For example, those proficient in forensic science, fingerprint comparison, combat skills, firearms knowledge, and crime scene investigation.

The Provincial Department is not short of these types of specialized elite talents; in fact, some talents, like those proficient in firearms and combat skills, are relatively plentiful.

However, comprehensive talents are rather scarce; those like Lu Chuan, who excel in every area, are especially rare.

Through investigating several cases, Lu Chuan’s importance in the major crimes team has already surpassed that of the team leader.

For instance, in this case, most of the crucial clues were discovered by Lu Chuan.

The escape paths taken by the robbers, the discovery of the robber’s short hair, and the DNA identification and comparison.

Ultimately leading to Chen Tianbao.

In two days, the investigation of the case has made significant progress.

Of course, it’s not that the major crimes team couldn’t solve the case without Lu Chuan.

Whether it’s Luo Qiang, Song Mingguang, or Wang Song, their directions were correct, and some clues have been obtained, providing some hints.

These veteran criminal investigation experts are truly rich in experience regarding solving cases.

For instance, Wang Song’s continuous pursuit of the source of the blast suits.

Although the process might be lengthy, it’s certainly possible to trace back to the source; once traced, the suspect can be locked down.

The only unknown factor is the time required.

Also, for instance, the content of call information that’s been under Song Mingguang’s scrutiny, who has interrogated Chen Tianbao.

Although the first interrogation did not result in actual progress, due to time constraints, Song Mingguang hasn’t had the chance for in-depth exploration yet.

Given time, it’s certain that Chen Tianbao can’t hide anything from Song Mingguang.

However, time is of the essence.

The path taken by Lu Chuan involves the shortest time, yields the most accurate results, and has the best directionality, hence it appears that each time in a case, it’s Lu Chuan who provides the vital clues and directions.

It’s not that others’ methods are ineffective, it’s just that Lu Chuan’s methods are quicker and more direct.

Chen Tianbao’s home isn’t in Binzhou City; he resides in dormitories provided by the bank where he’s a security guard.

Thus, the arrest operation is not complicated.

"There are eight people in the dormitory, all are security guards."

The personnel from the bank’s security department explained.

The bank’s dormitory is within a residential building, rented by the bank, specifically as accommodation for the security guards.

"Do you have a key?"

"Yes, we have a spare key."

"Director Li, directly open the door and arrest them inside."

Eight individuals, all security guards, with Chen Tianbao among them.

Li Donglin nodded, with Lu Chuan’s skills, taking down all eight at once wouldn’t be an issue.

Moreover, these eight security guards don’t belong to the same faction.

"Open the door!"

Click.

The door opened, Lu Chuan and others stormed in.

Since it was early morning, all eight were asleep.

The room had four bedrooms, each controlled separately, and soon a dazed Chen Tianbao was cuffed.

Twenty minutes later, Criminal Investigation Team’s interrogation room.

"Chen Tianbao, you informed the robbers that there would be a large cash deposit today, which prompted them to act, correct?"

Chen Tianbao, in his forties, appeared honest and straightforward.

"Officer, I don’t understand what you’re talking about. I already told you; I called my nephew and said nothing but inviting him to drink at my dorm tonight."

"Why are you arresting me?"

Drinking?

The interrogator, Song Mingguang.

"Chen Tianbao, Chen Zheng is the nephew you’re talking about, isn’t he?"

"Do you understand why we’re arresting you?"

Song Mingguang slapped a piece of paper onto the table.

"Do you think your nephew and others put on the blast suits, went through the sewers to evade the police, hid on the rooftops to avoid capture, and that’s the end of it?"

"Let me tell you, your nephew left a strand of hair when changing clothes on a self-built house’s rooftop."

"This is the DNA identification report of that hair, you still remember today’s blood draw, right? Your DNA information and that hair’s DNA information show a blood relation!"

"Can you now explain why hair related to you was found on the rooftop where the robbers hid?"

"I..."

Bam!

Song Mingguang suddenly banged on the table, startling Chen Tianbao.
