Detective Miller walked into a freezing cabin where a man sat dead at a wooden table. On the table sat a glowing electric space heater plugged into the wall, a cup of steaming hot cocoa, and a digital thermometer reading 32 degrees Fahrenheit. Miller noticed a thin layer of frost coating the inside of the windows. He knew right away the scene was staged. What proves it?
The hot cocoa
If the room is 32 degrees Fahrenheit (freezing point) and has been cold enough to frost the windows, a cup of hot cocoa would have cooled down and frozen solid very quickly, rather than staying 'steaming hot' next to a running space heater that clearly isn't warming the room.
