15. Sonny Liston, the former boxing heavyweight champ who was dethroned by Ali. Has a very mysterious life in general. His birth date was unknown so they’re not even sure how old he was. A boxer he was supposed to fight, Chuvalo, said he was dead in December 1970 when his body wasn’t even found until january 5, 1971. He was a heroin addict and they found heroin on him when they found him, but no needles or anything for him to inject with. Plus the amount in his body was thought to not be enough to cause an OD. However, some people close to him said he had a fear of needles, including his doctor, who said he would do anything to avoid taking shots.
Of course, many think he was murdered. Theories range that he was a debt collector who tried to ask for too much pay, that he was murdered by drug dealers, that he wasn’t paid for an alleged dive he took in the second Ali fight (and that when he threatened to go public about it he was killed), or that he was killed for not taking a dive against Chuck Wepner who he had fought a few months earlier.
Liston had well known underworld connections, and like I said earlier some suspected the second fight he took a dive against Ali.
