Dorothy Arnold's case is the most speculative. Did she commit suicide, because she was frustrated with her lack of success with her writing and her failed romantic prospects? Or was she the victim of a assault/murder, possibly by someone she knew?
There was speculation that DB Cooper and Richard McCoy were the same individual.
The vanishing at Hanging Rock is a work of fiction that's fooled many people into believing that the event really occurred. Rather like Bierce's "Oliver Larch" disappearance tale, which tends to get reported as fact.
Richard Colvin Cox is probably one of the better modern mysteries -- who was 'George', what did he do to Cox and why did he do it? Mary Shotwell Little's disappearance from Atlanta, GA in the 1960's in another bonafide 'what the hell happened?'.
