Civilian Sleuths is a new investigative podcast shining a forensic light on Australia’s most challenging unsolved murders and missing persons cases. For decades, these crimes have haunted families, investigators, and communities searching for answers—not for lack of effort, but because the tools of the past were limited. Using original source material, coronial records, archived media, and modern analytical tools, Civilian Sleuths recreates timelines, re-examines evidence, and explores theories that may have been overlooked for decades. But the most powerful tool remains public memory. Behind every cold case is a real person. A family. A life interrupted. And often, someone who still knows the truth. If you know something—no matter how small—it may matter. Launching January 6 with new episodes every second Tuesday, Civilian Sleuths invites you to become part of the investigation. Un
