Diary of a Criminal Investigator

Song Mingguang Bank.

Luo Qiang investigates the security company

Compared to the slow progress on Wang Song and Song Mingguang’s side, Luo Qiang found some valuable leads while investigating the security company.

The employee turnover at this security company is quite high, with many resignations and dismissals in the past period.

Some dismissed employees feel they were treated unfairly.

Thus, the conflict with the company is considerable.

"Not long ago, someone even came to make a scene."

In the meeting room, Luo Qiang was talking with some security personnel.

Outside the door, members of the Criminal Investigation Team were watching.

"Can you tell us specifically what happened?"

"There’s nothing I can’t say. The boss just told me not to speak out of turn, but I think there’s nothing to hide about it. The company is very strict, and frequently deducts money."

"Honestly, we’re just workers earning six or seven thousand yuan a month. To put it bluntly, we’re just slightly more advanced security guards."

"But if we make a mistake, we end up taking home only four or five thousand a month."

"For example, smoking in the dormitory results in a 100 yuan fine."

"We can’t even smoke in the dormitory?"

"Waking up late in the morning results in a 100 yuan fine."

"Eating slowly results in a 50 yuan fine."

"We work at this company 24 hours a day with no time for ourselves. Our waking and sleeping times, meal times, and even how long we spend eating are all regulated."

"The problem is, we’re not robots; people are bound to make mistakes sometimes."

"The company has established a patrol team specifically to pick on our faults and deduct money."

"Do you think the robbery might have been carried out by an insider?"

Luo Qiang suddenly asked.

The person hesitated: "I can’t say for sure, but... anything is possible."

"If it really was done by your former employees, who do you think is the most likely culprit?"

"Well..."

The person hesitated but clearly had suspicions.

"Regarding confidentiality, please rest assured. We will also have many people participate in the investigation, so you don’t need to worry about other matters."

"Moreover... this is an armed robbery, a serious crime. If you provide valuable information, you’ll be considered as having made a contribution, and there is a financial reward for that."

Financial reward?

The person paused upon hearing this: "Then I’ll say something, but it’s just a guess and might not be accurate. You can ask others later to see what they say."

"Last year during New Year’s, Li Chuan, Chen Zheng, and Zhang Xiaohu were caught smoking while transporting."

"The company deducted a thousand yuan from each of them."

"Isn’t the fine for smoking a hundred yuan?"

"That’s for smoking in the dormitory. Smoking in the vehicle results in a 500 yuan fine, and smoking while transporting results in a 1000 yuan fine."

"Actually, their transport tasks were already completed at the time. They smoked beside the vehicle after handing over the goods, but they got caught."

"The three of them were indignant. Deducting a thousand yuan around New Year, when salaries aren’t much, led to an outbreak of conflict."

"They argued with the supervisor, creating quite a stir in the meeting room, almost resulting in a fight. Then the company fired them during New Year’s."

"When they left, they said they’d make the company pay, but we never heard from them again and didn’t keep in touch."

"But the robbers this time are three people... I think it’s worth investigating."

Li Chuan, Chen Zheng, and Zhang Xiaohu...

After that, Luo Qiang went on to interview about a dozen people.

Some said nothing, while others spilled everything.

"Recently, the major conflict with the company involves Li Chuan and those three being fired during New Year’s. It was extremely unpleasant, almost leading to a fight, and they threatened to retaliate against the company. I think they should be investigated, but whether they did it, we don’t know."

"It’s definitely Li Chuan, Chen Zheng, and those three."

Many had similar suspicions.

Leaving the security company, Luo Qiang headed straight to the homes of Li Chuan, Chen Zheng, and Zhang Xiaohu.

Inside the security company, there were people familiar with Li Chuan who knew his address.

At the same time, Lu Chuan’s work had begun in earnest.

"Captain Lu, this batch of samples is from all personnel at the robbed bank."

The staff from the robbed bank were placed in the first batch of DNA information collection.

In Lu Chuan’s view, if there is an inside accomplice, the likelihood is highest among those at the robbed bank.

In the lab, Lu Chuan and six others busied themselves.

Currently, all parties are progressing smoothly.

Li Donglin had already reported to his superiors twice.

"The DNA identification results will be released tonight, and I’ll report back if there are any developments."

Ending the call, Li Donglin took a deep breath.

The major crimes unit had only taken over the case for two days, and to be honest, there were many clues, and progress had been significant.

However, clearly this did not meet the superior’s expectations.

Leaders don’t care about the process, only the results, focusing solely on when the suspects will be caught.

Li Donglin understood the superior’s perspective; as decision-makers, they don’t have the energy to worry about how many people the police have screened, how many leads have been found, how many have worked overtime, or who hasn’t slept for days.

But solving a case is a gradual process; you can’t catch a suspect just because you want to.

Usually, a change in quantity leads to a change in quality. Only when the groundwork is solid and the various leads are advancing can a particularly strong lead be found, directing us to arrest the suspects.

Based on Li Donglin’s experience, the current investigation had reached such a bottleneck.

Both on-site investigations and technical personnel were engaging in extensive work, and perhaps after tonight, tomorrow might yield positive results.

The facts proved Li Donglin’s judgment correct.

At 3:30 AM, Lu Chuan’s DNA lab called Li Donglin.

"Director Li! Chen Tianbao!"

"One of the people from the robbed bank named Chen Tianbao, his DNA information has a kinship relation with the DNA information of the short-haired suspect!"

"I suggest immediate arrest of Chen Tianbao!"

Lu Chuan hadn’t expected that testing only 32 DNA samples would lead to such a surprising result.

The DNA sample from a person named Chen Tianbao in the robbed bank showed a kinship relation with the DNA sample from the short-haired suspect.

Not immediate family, but they share a blood relation.
