The Dexter Killer: The Mark Twitchell Case

In 2008, Edmonton, Alberta became the center of a bizarre and disturbing murder investigation involving filmmaker Mark Twitchell. What initially appeared to be the disappearance of 38-year-old John “Johnny” Altinger would eventually expose a shocking story involving fake online dating profiles, deception, and a murder that prosecutors said was inspired in part by the fictional world of Dexter. In this episode of Stuttering in Silence, Gavin and Matt break down the timeline of the Mark Twitchell case, from his life as an aspiring filmmaker and his fascination with Dexter to the online deception that brought Altinger to Twitchell's garage. They examine the evidence investigators uncovered, the infamous “SKConfessions” document found on Twitchell's computer, the investigation that ultimately exposed him, and the trial that followed. Was Mark Twitchell attempting to turn fiction into reality, or was the Dexter connection exaggerated after the fact? Join Gavin and Matt as they explore one of Canada's most unusual and disturbing murder cases and the investigation that exposed the man behind the carefully constructed façade. #StutteringInSilence #MarkTwitchell #JohnnyAltinger #DexterKiller #TrueCrime #CanadaTrueCrime #EdmontonCrime #CrimePodcast #TrueCrimePodcast #Dexter
