A security guard reported hearing a smash in the museum gallery at 2:00 AM. When he arrived, the display case was shattered and the crown was gone. The guard stated he immediately locked all exterior doors. Yet, Detective Thorne knew the thief was still inside the building. How?
The guard locked the doors after the thief left
