When bright, young nursing student Maura Murray vanished on February 9, 2004, witnesses heard what they thought was a car crash and then saw Maura outside her vehicle on the side of the road but, moments later, when police arrived on scene, she was gone. Her disappearance has fueled a legion of online armchair detectives, causing an endless procession of blogs, books, websites and podcasts. "The Disappearance of Maura Murray" follows investigative journalist Maggie Freleng as she attempts to unravel a rabbit hole of unexplored leads, eyewitness discrepancies, missing evidence and questionable actions. With rare access to Maura's family and friends, many who have remained silent for years, including father Fred Murray and siblings Julie, Kathleen and Kurt, Maggie enlists the help of former US Marshal, Art Roderick as they investigate one of the most complicated and mysterious cold cases of the last quarter century. Maggie explores numerous theories by meeting with the people who have dedicated countless hours in searching for the truth, including Lance Reenstierna and Tim Pilleri the duo behind the widely popular "Missing Maura Murray" podcast, as well as true crime author, James Renner whose book and website about Maura's disappearance sparked tremendous controversy. From retracing Maura's last known steps to following various leads, the series will take viewers on a journey of what really happened and tackle the many unanswered questions. Was this case mishandled? Did Maura choose to disappear or was she a victim of foul play?
