The victim was discovered in a modern apartment with a digital clock flashing 12:00, a half-eaten sandwich, and a spilled glass of water. There was a total blackout across the city that night lasting from 10:00 PM to 4:00 AM. The roommate claimed he slept through the whole thing. The detective arrested the roommate. Why?
The roommate
A digital clock flashing 12:00 means the power has been completely cut and then restored. Since the city blackout didn't end until 4:00 AM, the power couldn't have just come back on by itself; someone had to physically flip the main breaker switch inside the apartment after 4:00 AM.
