So Evil

What possesses a human being to be so evil? It's a question that must be asked about Justin Stein. In one of the worst crimes in Australian history, at the beginning of 2022 he murdered nine-year-old Charlise Mutten. She had innocently put her trust in Stein, 31, hoping he could be a much-longed-for father figure in her life. In return, Stein shot the little girl in the face. He then thought he'd be able to get away with his despicable act by outsmarting the Homicide officers working to solve the case. He failed. On 60 MINUTES, Dimity Clancey is given unprecedented access to the extraordinary police investigation that caught this killer. She speaks with the lead detectives tasked with tracking Stein's movements through thousands of hours of CCTV footage, phone recordings and texts, and reveals how investigators were able to expose Stein's lies in exhaustive police interviews. Clancey's report also includes an exclusive interview with Kallista Mutten, Charlise's distraught mother and former fiancée of Justin Stein. Speaking publicly for the first time, Kallista tells 60 MINUTES about the loss of her precious daughter and the guilt she will always feel for inadvertently putting Charlise in harm's way.
