Conspiracy Theories

Ned Doheny, the only heir to one of the world's richest oil baron was found shot to death next to his childhood friend and secretary Hugh Plunkett in 1929. Investigators at the time ruled it a murder-suicide. But to this day, the crime is a source of rumor and speculation. Was it a muder-suicide or just made to look that way? Or was it tied to a bigger scandal involving millions of dollars, government contracts and bribery of a cabinet member.
