Chapter 570: Chapter 570: Motive for the Crime

At that time, there was no information about the suspect’s body characteristics.

Finding the criminal suspect among hundreds of people was like looking for a needle in a haystack.

Moreover, it was impossible to go through each person one by one, checking if they had passed by the district and so on.

However, the body characteristic information in Lu Chuan’s footprint identification report made a difference.

Comparing Suspect No. 1 and No. 2, Suspect No. 3 weighed over 100 kilograms, which was a very obvious feature.

"Although the foot traffic in the district is very high, we found this person passing by the supermarket entrance twice, both before and after the incident."

"Moreover, among all the people who passed by the supermarket and the dental clinic surveillance, only four individuals weighed over 100 kilograms and were obese."

"The criminal suspect would enter and leave the district, so they would definitely appear twice within the surveillance camera coverage over a period of time."

"I believe this person is a major suspect!"

On the surveillance, a fat man wearing a baseball cap and a mask appeared.

"Immediately investigate! Blue down jacket, baseball cap, blue mask!"

At this season, with winter just beginning, it was the high flu season, and many people on the street wore masks.

To say nothing of others, even among the dozen police officers in the meeting room, three were wearing masks.

However, the man in the video was clearly wearing the mask not because of a cold but to conceal his appearance.

Yet, without seeing his face, it didn’t matter; the clothes he wore wouldn’t change quickly.

Wang Song needed to keep an eye on anyone in that particular body characteristic, wearing the same type and color of clothes within a certain period, and maybe they could trace through the surveillance to lock onto him.

The progress in the case investigation was somewhat gratifying.

The Criminal Investigation Team of Tianzhou City had been busy for over half a month without discovering any clues, and then the major crimes team came and found a clue to the suspected No. 3.

That’s the difference.

One hour later, the major crimes team locked onto the information about the fat man and made the final confirmation.

Song Mingguang had obtained the video from the ATM.

There were two people who used the victim’s bank card for withdrawal, at different ATMs of different banks.

One of them was exactly the same as the fat man Wang Song’s team found!

It was certain that he must be one of the suspects!

With a certain clue, the investigation of the case could proceed along the trail.

The reason why the Tianzhou City Criminal Investigation Team struggled so hard in the first half-month was mainly due to the lack of any directional clues.

Although the whereabouts of the fat man were still unknown and there was no information about his appearance, at least this man wearing a baseball cap, mask, and blue down jacket was locked in as one of the current suspects.

Additionally, Song Mingguang discovered information about another suspect, who wore a black windbreaker, also with a baseball cap and mask.

These are the two people who made the withdrawals.

There was another person who had not appeared yet.

With the clues, Song Mingguang and Wang Song threw themselves into full gear.

Now with video footage of the suspect appearing on the surveillance, they could use the attire information to trace any possible traces of the suspect.

No. 38, Yingbin Road, Yingbin Lishuo District in Tianzhou City.

At the district entrance, there was a Rural Commercial Bank ATM. 𝗳𝚛𝚎𝚎𝘄𝕖𝕓𝕟𝕠𝚟𝚎𝕝.𝗰𝕠𝐦

After the incident, someone with physical characteristics suspected to be of Suspect No. 2 withdrew 20,000 yuan from this ATM.

The Crime Scene Investigation personnel from the Tianzhou City Criminal Investigation Team were wiping fingerprints on the ATM.

Although half a month had passed, with many people using the ATM, they still held onto the one-in-a-thousand chance hoping the suspect left prints in negligence.

Standing before the ATM for a while, Song Mingguang’s attention shifted to some nearby shops.

Could the suspect possibly live in Yingbin Lishuo District?

It was possible but unlikely.

Judging from the suspect’s cautiousness, they had a certain counter-reconnaissance awareness.

Would they take a risk, betting that the police didn’t know they had taken two bank cards?

Song Mingguang believed it was unlikely; if the suspect wasn’t so cautious, they might have already been caught in previous crimes.

But they still needed to investigate Yingbin Lishuo District.

Song Mingguang entered a supermarket beside the district’s gate.

Sure enough, there were surveillance cameras inside the supermarket.

Most supermarkets indeed have surveillance cameras to prevent some customers from stealing.

These surveillances are mostly without blind spots.

And maybe they could capture some situations outside the supermarket through the windows.

Song Mingguang and Wang Song pressed on their investigation relentlessly, making progress step by step, seemingly one step away from catching the suspect.

The discoveries made by the two also boosted the morale of the police officers from the Tianzhou City Criminal Investigation Team.

They had been working hard for half a month, working overtime every day, yet finding nothing.

Now, with the major crimes team arriving for less than a day, such critical clues were found.

Frontline police officers weren’t afraid of overtime, or the exhaustion of work, as long as their efforts yielded feedback and results.

Things were different now.

Tracking the suspect’s footsteps during the crime seemed to bring them closer to their target.

At 7 PM, Wang Song made significant progress.

"Director Li, three days before the incident, at the Tianyuan Hot Pot Restaurant beside the crime district, the victim had a conflict with three men!"

Half an hour later, Wang Song returned to the Tianzhou City Criminal Investigation Team with an excited look, holding a USB drive.

"It should be these three people!"

Opening the video, it showed the victim’s family of three.

After a while, an arm reached over from behind the male victim.

The man turned around, seemingly saying something.

Then an argument broke out.

However, because of a screen obstruction, the surveillance camera didn’t capture the faces of those clashing with the victim’s family.

"I’ve already been to this hot pot restaurant, and the waiter at that time had an impression of the conflict that day."

The conflict originally happened because the child in the victim’s family was playing with a paper airplane.

"The airplane flew into the hot pot of the three men eating opposite."

"One of the men, from the waiter’s description of his body shape, was the comparatively fat Suspect No. 3, demanded an apology from the child."

"However, they refused to apologize, claiming the child was too young, and thus the argument started."

The argument escalated quite vehemently, but there was no physical fight; the three men left without continuing to eat.

So that’s it.

This seemingly explained why the perpetrator cooked the child in the hot pot.
