Dhu Shanatir
Dhu Shanatir also spelled Zu Shenatir, was a Himyarite king who ruled Yemen for 27 years. He was not from the royal family. He was known as "The Man with Earrings".
He is known as one of the first recorded serial killers. He lured young boys from the royal family into his home with the promise of food and money, stripped them naked and sodomized them. He then killed them by throwing them naked out of an upper story window of his home. He was only stopped when a would-be victim, named Zara'h, stabbed him in the anus. Following his assassination, Dhu Shanatir's decapitated head was displayed from the palace window and Dhu Nawas assumed rulership of the Himyarite Kingdom.
