The sense of mystery created by the music of the Doors, specifically their charismatic frontman Jim Morrison, has helped make it hard for some people to believe that he's truly dead. Of course, the fact that an autopsy was never performed doesn't help, either.

The singer reportedly died on July 3, 1971 -- again, at the age of 27 -- of heart failure in the bathtub of his Paris apartment. In accordance with French law, since there was no sign of foul play, no further investigation was performed. However many people suspect that Morrison in fact died of a heroin overdose, possibly in the bathroom stall of a nearby club. Or... maybe he faked the whole thing and is raising horses in Oregon.
