Casefile True Crime Podcast, or simply Casefile, is an Australian crime podcast that first aired in January 2016 and is hosted by an Australian man who remains anonymous. The podcast is released on a Sunday (EST) for three consecutive weeks, with a break on the fourth week. The series deals with solved or cold criminal cases, often related to well-known murders and serial crimes. Many early episodes relate to Australian cases (e.g. Port Arthur or the Snowtown murders), although notable crimes from the UK and the USA are increasingly featured, and well-known cases from other countries have also been included. Unlike a number of similar podcasts, the series is scripted and narrative, relying primarily on original police or mass-media documents, eyewitness accounts, and interview or public announcement recordings. Larger and more-complex cases have received multiple-week serialised broadcasts, and case updates to previously aired cases are also provided from time to time. The series has been well received, and has won a number of awards since its debut.
