The images on several screens instantly froze in place.
"Bottom left corner, third screen. Camera ID LY-07-Road-142. The timestamp is 10:23:17 AM on the day of the incident. The person at the bottom-left edge of the frame, the one who just came from behind the newsstand."
Yang Qi's voice was clear. "Zoom in. Focus on him."
The officer immediately did as instructed, isolating the image on the main screen and repeatedly zooming in and enhancing its clarity.
Since the shot was from the periphery and the subject seemed to have deliberately avoided facing the camera, all the footage caught was a figure in a baseball cap with the brim pulled down low, revealing half of a gaunt side profile and a stubbled chin.
He wore an ordinary gray shirt and appeared to be carrying something, but it was mostly obscured by his body as he strode quickly out of the camera's range.
