Ren Qiang's Team 2 was responsible for questioning, while Sun Jun's team conducted investigations in the surrounding areas and retrieved surveillance footage.
Around the East Suburb Wood Factory, there were other factories, some of which operated around the clock in three shifts.
"Did your furniture factory notice anything unusual last night when you were working overnight?"
"How are we supposed to notice? The noise inside the factory is too loud, we couldn't hear a thing, and we didn't notice anything unusual."
"Go fetch the surveillance footage from the cameras at the intersection and at the factory entrance. You should be able to see clearly who's coming in and going out."
Retrieving the surveillance footage went smoothly, but its content left Sun Jun disappointed.
The surveillance camera at the East Suburb Wood Factory's entrance had been broken for a week and captured nothing the previous night.
