Incest And Murder
As if murdering 6 million Jews wasn't enough, many conspiracy theorists believe that Hitler also murdered his niece, Angelika "Geli" Raubal. Geli was the daughter of Hitler's half-sister, Angela, and by all accounts, Hitler was found of his young niece. The site Historic Mysteries notes: "The rumors were not only sexual it seemed to some that Geli was a sort of prisoner of Adolf's. He denied this publicly, but the fact is that she was a vibrant young girl who certainly lived under his thumb." Geli died of a gunshot wound at the age of 23 and her death was ruled a suicide.
