The sprawling, endless investigations of the murders of Biggie Smalls and Tupac have now seen one more twist. According to Murder Rap, a new book by ex-LAPD detective Greg Kading, it was Sean Combs who hired a hitman to kill Tupac, presumably as an extension of the East Coast-West Coast beef. In this scenario Biggie was killed in direct retaliation to Tupac’s murder by a hitman hired by Suge Knight. L.A. Weekly reached Combs for comment, and he replied, “This story is pure fiction and completely ridiculous.” Knight did not respond. So, how believable does this sound?
