9. Oro
Second-generation lucha libre star Jesús Javier Hernández Silva worked as Oro, beginning his career in 1990 only to see it end just three years later. Oro was working a trios match when he took a bump that was designed to look as if he’d broken his neck. Unfortunately, it’s believed he did, collapsing in the ring and dying before he even made it into an ambulance. Oro’s family requested an autopsy not be performed, but speculation has it he died of an aneurysm.
