    The Australian Family Cult That Vanished Overnight

    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?

    The Family Friend No One Suspected

    Her life changed forever when her five-year-old daughter, Rose, bravely spoke up about a trusted family friend sexually assaulting her. 

    That moment led Michelle to discover that both of her daughters had endured abuse for years, and it marked the start of the family’s journey toward justice and healing.

    In this episode, Michelle shares how she and her daughters, Pippa and Rose, navigated their challenges together, supported by their older sister Maggie and their father. Now adults, Pippa and Rose are using their voices to drive positive change in the way child victims are treated within the legal system. Their journey is a powerful testament to resilience, courage, and the unbreakable strength of family in overcoming adversity.

    The Woman So Obsessed With Killers She Became One

    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.

    The Husband Who Played Grieving Widower After Killing His Wife

    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.

    If you need support, it's available at 1800 RESPECT.

    Trenny Gibson Went On A School Trip And Never Came Home

    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

    The Brutal Melbourne Killer Who Never Went To Prison

    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.

    The Deadly Obsession That Drove Jodi Arias To Murder Her Lover

    The case of Jodi Arias, the woman who murdered her former lover, Travis Alexander, in 2008, captivated audiences around the world. When the trial began in 2013, media coverage intensified, driven by a disturbing question: what could compel a young, attractive woman to kill so violently? To shoot, stab, and nearly decapitate a man she claimed to have loved?

    These are just some of the questions journalist Briana Whitney set out to explore in her True Crime Arizona documentary, Obsessed: Unravelling Jodi Arias.

    Whitney has even been in direct contact with Arias herself, who continues to blog and exchange emails from inside her prison cell.

    The Missing Australians You’ve Never Heard Of

    Two 15-year-olds vanish after heading to a disco in Wollongong.

    An 18-year-old Belgian backpacker disappears after a night out in Byron Bay.

    A 20-year-old Navy recruit vanishes from a casino lobby in a matter of minutes.

    These are just a few of Australia’s missing persons cases you may never have heard of. Each year, more than 56,000 people are reported missing across the country. Most are found. But over 2,500 remain missing long-term, their names and stories slowly fading from public memory.

    Nicole Morris, Director of the Australian Missing Persons Register and author of Vanished and Missing, refuses to let them be forgotten.

    What Happens When Your Ex Hires A Hitman To Have You Killed

    Who would try to hire a hitman to kill an innocent young girl? 

    In early 2021, Riley ended a relationship with a man she had been in a year-long online relationship with after she alleges he assaulted her. Despite the breakup, he continued to message her relentlessly. 

    Instead of backing down, Scott escalated his feelings of anger, turning to the dark web. He paid $19,000 AUD to hire a hitman to kill her.

    The reality of the plot became clear when police knocked on the door of Riley’s family home. It was her mother, Jamie Elder, who answered, learning that someone had tried to arrange her daughter’s murder.

    Jamie is now Riley’s advocate, fighting for justice while the man accused of orchestrating the hit walks free. You can follow Jamie on TikTok and support her advocacy here.

    He Killed His Entire Family, Then Walked Free To Start Another

    On September 7, 1971, at a remote farmhouse 40 kilometres south of Adelaide, Clifford Bartholomew killed 10 people. His wife, his seven children, his sister-in-law and her 19-month-old son. He shot them all dead.

    He was sentenced to death, but because of changes to the law, he wasn’t killed. Instead, he was re-sentenced to life in prison and managed to serve just eight years before being released on parole.

    He changed his name, his identity and created an entirely new family who knew nothing about his previous life or his crimes… until now.
