Emilio Sorrentino was a Werewolf and the Alpha of the North American Werewolf Pack before his son Dominic took over. He was Alpha during the events of the short story Infusion set in 1946 and was present when Malcolm Danvers met the mother of his future son but did not speak. He gave Malcolm the job of hunting down and terminating a troublesome mutt at Malcolm's request. Clayton Danvers states in Savage that Emilio saw two thirds of his Pack dead by the time they were forty years old and that Dominic had been Alpha for nearly twenty years at that point- 1970. This means that Emilio was no longer Alpha by the early 1950's, whether he had died then or later is unknown.
