A perfect crime? To me, it's full of flaws!

Half an hour later, in the conference room of the Image Investigation Division of the S City Public Security Bureau.

The large screen was playing CCTV footage from the mall's underground parking lot. The footage had been sped up, causing the images to flicker.

Qin An, Liu Yuanshan, Lin Haitang, and Qi Feng sat at the table, staring intently at the screen.

"Stop!" Qin An suddenly shouted.

The operator immediately pressed the pause button.

The image is frozen at 2:15 a.m. on the night of the incident.

A black van without license plates was parked at the edge of a blind spot in the surveillance camera's view.

A few minutes later, a figure wearing a long black waterproof trench coat, a black baseball cap, and a black mask appeared in the frame.

He was pushing a supermarket shopping cart. On the cart, there was a huge brown bear plush toy.

Because the doll was so big, it almost covered most of his body.

"It's him," Liu Yuanshan said in a low voice.

"Enlarge the face," Qin An ordered.

The operator selects the suspect's face and zooms in and sharpens it.

The image became clearer.

However, the suspect's face was completely covered by a mask and hat brim, with only his eyes showing.

Those were extremely calm eyes.

There was no panic, no tension. He even slightly raised his head and looked directly at the camera as the cart passed a surveillance camera.

His eyes held a chilling indifference and provocation.

Qi Feng stared at the pair of eyes on the screen, his fingers lightly tapping the table.

"He knew there were surveillance cameras," Qi Feng broke the silence. "He deliberately let us see it."

Lin Haitang frowned: "Is he provoking the police?"

"He's putting on a show," Qi Feng corrected. "He thinks he's created a perfect work of art. The van can't be found to have a license plate, and his disguise is flawless."

"Continue tracking this van's route," Liu Yuanshan ordered. "Since he drove here, he must have left a trace. The Skynet system isn't just for show."

The operator immediately retrieved surveillance footage from the parking lot exit and surrounding roads.

Ten minutes later.

"Old Liu, Team Leader Qin," the operator wiped his brow, "after this bread truck left the mall, it entered Jianshe Road in the north of the city. There's road construction going on there, creating a three-kilometer-long blind spot for surveillance cameras. After the truck entered the blind spot... it never came out again."

The trail went cold.

The air pressure in the conference room dropped to freezing.

Qi Feng stood up, walked to the big screen, and stared at the figure pushing the handcart.

"He's wearing a long trench coat to conceal his size. His even stride while pushing the cart shows he's strong and has good stamina." Qi Feng stared at the screen. "But look at his left leg."

Everyone looked at the screen.

"When he pushed the cart uphill, his left knee bent less than his right, and he mainly relied on his right leg for support." Qi Feng turned to Qin An, "Senior Brother, what does this mean?"

Qin An's eyes lit up: "His left leg has been injured, or he has a chronic joint disease that makes him unable to withstand heavy pressure."

"We will screen all eligible men in the city who have a history of old injuries to their left leg," Liu Yuanshan immediately decided.

"Master, the scope is too broad." Qin An shook his head.

Qi Feng took the mouse and rewound the screen to the spot where the suspect pushed the cart past a puddle of water.

"Zoom in here," Qi Feng said, pointing to the ground.

On the screen, the suspect left a blurry shoe print after stepping through the water.

"The sole pattern is very unique; it's not like the sneakers or leather shoes commonly found on the market." Qin An leaned closer to the screen. "It looks more like some kind of special work shoes."

Qi Feng stared at the shoe print, and a small spot on it caught his attention.

"Zoom in here!" Qi Feng said, pointing to a spot on the picture.

When the image was enlarged, sure enough, a tiny amount of red soil was attached to the sole of the shoe.

"Red soil...where is there red soil?" Liu Yuanshan looked at Qin An, this was his territory, he was more familiar with it.

"A brick factory? Or something else?" Qin An, a forensic investigator, wasn't actually that familiar with S City.

"Is it over at the abandoned chemical plant in the north of the city? There are many privately owned brick factories there," a young policeman said.

"Qin An, take a team and go to the abandoned chemical plant in the north of the city immediately," Liu Yuanshan ordered upon hearing the policeman's words.

"Yes!" Qin An turned and rushed out of the conference room.

Qi Feng followed behind, casually picking up the car keys from the table.

You can't escape this time... I've caught you by the tail!
