A night watchman claimed he fell asleep and woke up to find the office safe blown open with dynamite. Investigators found a heavy soot mark on the wall directly above the safe door, but the watchman's face and uniform were completely clean. What did the forensic team deduce?
Safe direction
An explosive blast powerful enough to blow open a steel safe generates a massive backdraft of black smoke, soot, and debris directly outward. Standing close enough to guard or blow it would coat a person in soot instantly.
