Detective Thorne found a suspect dead from a gunshot wound in a locked hotel room. The gun was in the victim's right hand, but the bullet entered from the left side of the room through an open window, and the victim was notoriously left-handed. Furthermore, the television was tuned to a morning cartoon, but the clock read 3:00 AM. What exposed the staged murder?
The television and the time
Cartoons do not air at 3:00 AM, proving the television was turned on long after the murder occurred to manipulate the timeline.
