Detective Miller walked into a dimly lit room where a collector sat dead at his desk. A shattered glass of iced tea was on the floor. The air conditioning was turned off, yet frost coated the inside of the windows. Miller immediately called for forensics. What was unnatural about the scene?
The frost
Frost only forms on windows when the interior temperature is significantly colder than freezing and moisture is present. With the AC turned off in a warm room, frost could not form on the glass naturally, indicating dry ice or chemical tampering was used.
