Some mysteries seem impossible, but few actually are. But with no logical explanation to be found, could you solve the unsolvable? Is there even such a thing? Today we look at two impossible cases. First, a man is found shot to death with three bullet wounds in his body, alone, with no gun, inside a locked and bolted room. What happened? Any guesses? How about this one: a woman boards a completely empty train car very much alive. Less than a minute later the still-empty train car pulls into the next station. Somehow she has been stabbed in the back, still alone in the car and now very much dead. Who done it? Your guess is as good as ours.
