Before entering the room, Lu Chuan put on the full set of crime scene investigation equipment.
Since Wang Feng was expelled last year for undercover work, his relationship with his parents was not particularly good, so even though he had been missing for three days, his parents did not know he was missing. If Yang Lin hadn't called them to report the case, they might still be unaware of Wang Feng's current situation.
Therefore, his parents hadn't been in the room, and the current state of the room should be the first scene after Wang Feng's disappearance.
"Brother Hui, hold on a second, I'll scan for fingerprints first."
Putting on gloves, Lu Chuan took out a portable ultraviolet flashlight.
Although using an ultraviolet flashlight to check for fingerprints during the day is not particularly precise, Lu Chuan only needed to find the fingerprints for now, not collect them immediately.
