True Crime Conversations

In 1991, a fire at an Austin yoghurt shop led firefighters to a scene so horrific it would haunt them forever: four teenage girls murdered in one of Texas’ most shocking crimes.
The Yoghurt Shop Murders became a case that devastated families, traumatised a city, and remained unsolved for more than three decades. Now, thanks to advances in DNA technology, investigators believe they’ve finally identified the killer.
Margaret Brown, director of HBO and A24’s The Yoghurt Shop Murders, explains the wrongful confessions, the families’ fight for answers, and the extraordinary twists that changed everything.

In August 2025, two Victoria Police officers were shot and killed while executing a search warrant at a regional Victorian property linked to Desmond Filby, also known as Dezi Freeman. A third officer was injured, and Filby vanished into the bush, triggering a seven-month manhunt that gripped the nation.
The case began with a child abuse investigation and ended in March 2026, when police found Filby hiding in a shipping container and shot him dead after he threatened officers with a stolen police gun.
In this episode, we unpack the tragedy, the investigation, and the dramatic final chapter of one of Australia’s most confronting police operations.

WA Police have acknowledged that earlier searches in the investigation into the Nannup Four were conducted in the wrong location. Retired detective Barry McIntosh, who has long pushed for answers in the case, believes the corrected coordinates point to a more accurate search area near Northcliffe, where clothing and the reported smell of human remains were allegedly detected after the group disappeared.
Today, we check in with ABC investigative journalist Dominique Bayens about the latest developments in the case.

29-year-old Katie Haley arrived home on a Friday night in March 2018 after a long shift at a Melbourne tavern. Her partner Shane had been messaging throughout the day, calls, accusations, jealousy, and control that had continued for hours...
After reaching her limit, Katie stands up and starts packing a bag. She tells him the relationship is over. She’s leaving with their daughter. But she never makes it out the door.
Today, we’re speaking with Katie’s sister, Bianca Unwin, who has since become an advocate for domestic violence awareness following her sister’s death, and who now speaks openly about coercive control and the warning signs that were not fully recognised at the time.
