True Crime Conversations

Katherine Knight, Sarah Makin, Caroline Grills, Catherine Birnie, Helen Moore, and Rachel Pfitzner are among the most notorious female killers in Australian history. But what compels a woman to take a life, whether it’s someone close to her or, more rarely, a stranger? Dr Xanthe Weston, a criminal psychologist, has long been driven by this very question. Drawing on years of research into cases like these, she joins us today to explore what she’s discovered - why women’s motives for killing often differ from men’s, and whether some perpetrators are inherently predisposed to violence, or shaped by circumstance.

In 1984, Terry Ferguson was approached in a busy Florida mall by a charming photographer with an Australian accent. He promised her stardom; instead, she became a victim of Christopher Wilder, the notorious "Beauty Queen Killer." While Wilder’s confirmed body count sits around 11, new evidence suggests a much darker reality: a trail of over 30 victims stretching from Australia to America.  Today, we explore Wilder’s predatory tactics, his transition from serial to spree killer, and his potential connection to Australia’s infamous, unsolved Wanda Beach murders.

In 2007, a family of three and their friend vanished from their secluded home in Nannup, Western Australia, leaving only a cryptic note claiming they had moved to Brazil. They never arrived. As investigators delved into the lives of Chantelle McDougall, her partner Simon Cadwell, their daughter Leela, and friend Tony Popic, they uncovered a web of doomsday prepping and cult-like spiritual beliefs. Was this a voluntary disappearance to a "higher plane," or something far more sinister?

Some women dream of launching a career before 25. Some dream of owning their first home. Jemma Lilley had a different goal: she wanted to kill someone before her 25th birthday, but she knew she couldn't do it alone.  Obsessed with serial killers and violent fantasy, Lilley set her sights on turning desire into reality. She found an accomplice in Trudi Lenon, an impressionable single mother whom she gradually drew into her world of fixation and planning. Together, they searched for what they chillingly described as the “perfect victim.” They chose 18-year-old Aaron Pajich-Sweetman, a vulnerable teenager who was a friend of Lenon’s son. It is a case that still shocks those who hear it. A real-life horror story about manipulation, obsession, and the calculated, meticulous planning of two women who conspired to take the life of an innocent young man.

In June 2016, Karen Ristevski vanished from her home. Her husband, Borce, told their daughter she had gone for a walk and never returned. For months, police and family searched in vain. Then, in February 2017, hikers stumbled upon her skeletal remains in a quiet nature reserve. Police pieced together CCTV footage and phone records, leading to Borce’s arrest. He pleaded guilty to manslaughter in 2019, after prosecutors were unable to prove intent. Now, 7NEWS Investigations Editor Alison Sandy is digging deeper, not just into Karen’s case, but into a disturbing pattern: women whose deaths could have been prevented or discovered earlier, had the warning signs of escalating intimate partner violence been recognised sooner.

In October 1976, 16-year-old Trenny Gibson boarded a school bus in Knoxville, Tennessee, expecting a routine day. Instead, her horticulture class was taken on a rainy hike into the Great Smoky Mountains National Park without warning. Unprepared and uneasy, Trenny borrowed a jacket from a fellow student. By mid-afternoon, she was gone. One moment she was on the trail, the next she had vanished. Nearly 50 years later, her disappearance remains unsolved. Questions linger about suspicious behaviour, missing evidence, and why the case quietly faded from view. In this episode, we speak with podcast hosts Tim Pilleri and Lance Reenstierna about their investigation into the haunting mystery of Trenny Gibson.  You can listen to Tim and Lance's podcast Missing, here and watch their YouTube videos here.  Listen to Claire Murphy on Missing here.

In May 2019, 25-year-old Courtney Herron was murdered after a night out in Melbourne’s CBD. What happened next would ignite national outrage and raise disturbing questions about justice in Australia. In this episode, Courtney’s father, John Herron, speaks about the daughter he loved deeply, her generosity, humour, and instinctive kindness, and the night she crossed paths with the man who killed her. He lays bare the failures he witnessed inside the justice and mental health systems, and explains why, as both a grieving father and a lawyer, he believes Courtney was denied justice. You can read more from John Herron in his writing for Mamamia, including his powerful open letter about Courtney’s death, here.
