In October 2008, a 38-year-old Edmonton man named Johnny Altinger told friends he had a date with a woman he met on a dating site. He never came home. Altinger had been lured to a rented garage in Edmonton and murdered by Mark Twitchell, a filmmaker who weeks earlier had shot a short film about a man luring victims to a garage to kill them, and who was so fixated on the series Dexter that the press would name him for it. A week earlier, another man had been attacked in that garage and escaped. On Twitchell's laptop, police recovered a deleted document titled SKConfessions: a first-person account of both attacks, written in the voice of a serial killer. In this episode of Murder: True Crime Stories, host Carter Roy examines the fake dating profile that lured Johnny Altinger, the earlier victim who got out of that garage alive, and the deleted document that prosecutors read to the jury at his murder trial as a confession dressed up as fiction. Please note, this episode contains descriptions of extreme violence and may not be suitable for all audiences.
