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. Unsolved. Unforgotten. Unfinished. Listener discretion advised.

    Margaret & Seana Tapp - Series 3 Trailer (1984)

    For almost a day, no one realised anything was wrong. A neighbour assumed Margaret was sleeping after studying. A schoolfriend noticed Seana wasn't at school. Inside their home on Kelvin Drive, a mother and her nine-year-old daughter were already dead. On a winter night in August 1984, Margaret Tapp - a 35-year-old nurse, single mother of two and law student - and her nine-year-old daughter Seana were murdered inside their home in Ferntree Gully, at the foot of the Dandenongs. Margaret had arranged a babysitter, confirmed a date for the opera the following evening, and had been seen through her front window studying. Sometime after dark, someone came to the house. A red utility was seen parked in the street that night and was never traced. Their bodies were discovered nearly a day later, when Margaret's date let himself into the house through a sliding door at the rear. More than two decades later, a DNA breakthrough led to charges, but the evidence ultimately collapsed because of laboratory contamination. More than four decades later, the murders remain unsolved. In Civilian Sleuths, we return to the original police brief and the 1986 coronial inquest - witness statements, the timeline and the forensic record - to rebuild Margaret and Seana's final hours from the documents themselves, and to examine what the investigation focused on, and what it may have missed. Episode 1 premieres 4 August. Subscribe now.

    Bonus Update: A Note to Listeners and Contributors

    A short update at the close of the Mary Anne Fagan series. Thank you to everyone who listened, shared the series, spoke about Mary Anne with family or friends, or reached out privately with memories and material connected to the case. Something has become clear across this series: people are still remembering. Nearly fifty years on, a familiar name, a street or a workplace has been enough to bring back memories long set aside — and following the series, information has been provided to Crime Stoppers. This is a reflection on why these stories are still worth telling, and why the window to tell them won't stay open forever. If this series brought something back — however small, however uncertain — you're encouraged to contact Crime Stoppers on 1800 333 000. Civilian Sleuths returns soon with its next series.

    Mary Anne Fagan - Someone Knows Who He Was (FINALE)

    She wouldn't open that door for anyone. She opened it for a uniform.  The investigation into Mary Anne Fagan's murder was consumed by a gravity well: the systematic dishonesty of "James," a council labourer whose lies about gambling, unauthorised absences, and sexual bravado absorbed the full bandwidth of the Homicide Squad's questioning.  The lies were real. The concealment was real. But what "James" was hiding may never have been murder.  While that gravity well pulled everything toward it, two independent witnesses — who did not know each other — described a man in military-style uniform behaving in a manner consistent with someone leaving a crime scene. That man was never identified. So the series ends on the question it was always building toward. When a RAAF Group Captain's wife is home alone, in a locked house, midway through dyeing her hair — a process she would not interrupt for anyone — what is the one thing that makes her open the door without hesitation? A man in her husband's service uniform. Not the council worker she'd spoken to about the rubbish that morning. A uniformed airman. Because a uniformed airman at the door of a military officer's home, while the officer is away overnight, means something has happened. You don't check through the screen door. You don't finish your hair. You open the door. The Homicide Squad closed the book on the man who lied. They never opened it on the man in the uniform — because they never found him. He walked out the Fagans' front gate at 12.10pm and into forty-eight years of silence. No one ever asked him a single question. Mary Anne never washed it out. Neither did the men who were meant to find her killer.

    Mary Anne Fagan - They Didn't Fit The Timeline

    They thought they had him. For more than sixteen hours, his answers kept changing. He was never charged. In April 1978, two months after Mary Anne Fagan was murdered in her own home, the Homicide Squad sat a man down in Russell Street and worked through his movements, his money, and what he had said about her. By the end, he had been caught in contradiction after contradiction. The Coroner would later name him in open court as far from honest. He walked free. For forty-eight years, the gap between what police believed and what they could prove has remained open. Here, we stop assuming and start testing. Four conditions any explanation of this murder has to meet — the door, the blood, the cigarette, and the departure — are held against both men the investigation pursued: the man at the corner, and the man at the gate nobody ever named. One thread comes apart. The other has been sitting in an institutional shadow since 1978. Content warning: this episode discusses murder and includes explicit sexual language drawn from sworn inquest testimony. Listener discretion is advised.

    Mary Anne Fagan - He Didn't Tell Police

    Police had the omissions, the contradictions, the missing time, the money, the alibi problem, and the forensic traces. If that still wasn’t enough, what was missing? On the morning Mary Anne Fagan was murdered, three council workers were repairing the road outside her Armadale home. One of them had spoken to her directly. One of them later admitted making graphic sexual remarks about her while sitting on a fence facing her house. One of them left the worksite during the period investigators came to treat as the murder window. And one of them would later sit through hours of homicide questioning as detectives tried to pull apart his account of that day. His name was “James”. Across statements, interviews, forensic evidence, witness accounts and the 1979 inquest, investigators believed a pattern had emerged: omissions, contradictions, unexplained money, a disputed bookmaker alibi, a boot print, microscopic bitumen-like flecks found in the house, and a man the Coroner would later describe in open court as “far from honest”. By the end, the case against “James” looked substantial. And yet, no charge followed. In this instalment of Civilian Sleuths, we follow the evidence that made “James” the focus of the investigation — and the unanswered gap that has remained for more than 48 years. Content warning: this episode discusses the murder of Mary Anne Fagan and includes references to sexually explicit language quoted from sworn inquest testimony. Listener discretion is advised. If you have information about the murder of Mary Anne Fagan, contact Victoria Police Crime Stoppers on 1800 333 000, or submit a confidential report online at police.vic.gov.au/crime-stoppers.

    Mary Anne Fagan - The Best Lead

    What if the best witness in the case was eventually treated as if he had seen nothing at all? At 12.10pm on the day Mary Anne Fagan was murdered, a retired Navy serviceman saw a man in RAAF uniform walk out of the front gate of 575 Dandenong Road. He reported it to police less than 24 hours later. Detectives called it their best lead. A statewide investigation followed. RAAF bases across Victoria were searched. Identity parades were conducted. A photofit was published nationally. And then the investigation changed direction. This instalment walks through the witness sightings, the timeline, and the institutional shift that moved detectives away from the man in uniform — despite two independent witnesses placing him on Dandenong Road that afternoon. Content warning: This series discusses sexual violence and the murder of a mother of five. This episode includes references to post-mortem examination and children discovering their mother after her death. Listener discretion advised. If you have information, contact Victoria Police Crime Stoppers: 1800 333 000 or police.vic.gov.au/crime-stoppers. The reward for information leading to an arrest and conviction is $1,000,000.

    Mary Anne Fagan - The Man Who Walked Out The Front Gate

    Who had the opportunity to enter a house, in the middle of the day, surrounded by witnesses, and not be seen? On Friday, 17 February 1978, Mary Anne Fagan was last spoken to at approximately 10:30am inside her home at 575 Dandenong Road, Armadale. By mid-afternoon, she was dead. This episode follows the investigation from the moment police arrived — through sixteen months of forensic examination, witness statements, and formal inquiry — to the only findings the evidence could support. What was established. What was not. Who came forward — and who did not. The lead described by the head of Homicide as the most significant — and where it led. Because at approximately 12:10pm that day, a man was seen leaving through the front gate - and he was never publicly identified. Content warning: This series discusses sexual violence and the murder of a mother of five. This episode includes references to post-mortem examination and children discovering their mother after her death. Listener discretion advised. If you have information, contact Victoria Police Crime Stoppers: 1800 333 000 or police.vic.gov.au/crime-stoppers. The reward for information leading to an arrest and conviction is $1,000,000.

    Mary Anne Fagan - The Door Wouldn't Open

    A Friday morning in Armadale. An ordinary suburban street. A crime that remains unsolved. On 17 February 1978, Mary Anne Fagan — a 41-year-old mother of five — was killed inside her home on Dandenong Road, Armadale. No one has ever been charged. That morning, she got her children off to school, spoke to her husband on the phone, and set up the bathroom to dye her hair. A few hours later, three of her children came home from school. The door wouldn't open. Civilian Sleuths returns to coronial records, witness statements and contemporaneous reporting to reconstruct the morning minute by minute — from the council work crew on the corner, to the neighbour who saw Mary Anne drive past, to the uniformed man seen leaving the house just after midday. Someone saw something that day. Someone still knows. If you have information, contact Victoria Police Crime Stoppers: 1800 333 000. Content Warning:  This episode discusses the murder of a woman in her home, including children discovering their mother. Listener discretion is advised.
