Episode 5

Halliwell said, “Have you got a car? We’ll go.” Instead of taking him to the police station (with access to a lawyer), Fulcher agreed—Sian could still be alive. Fulcher used an exception to the rule for urgent interviews when a life is at stake. Hosted on Acast. See acast.com/privacy for more information.

Episode 8

It was argued that although Fulcher could invoke the ‘urgent interview’ provision for Sian, once Halliwell suggested there could be a second victim, Fulcher should have ignored that confession and taken him directly to the station. Hosted on Acast. See acast.com/privacy for more information.

Episode 10

It took five years for Halliwell’s trials to conclude. By then, Steve Fulcher had left the police force—leaving behind the biggest question of all: When a killer confesses, do you listen? Hosted on Acast. See acast.com/privacy for more information.

The Phillip Island Murder was featured on an episode of Sensing Murder in 2005, and then became Case 80: Beth Barnard on Casefile in 2018. Casefile Presents asked Vikki to explore the case in a long-form series. Hosted on Acast. See acast.com/privacy for more information.

One would be linked to the infamous Easey Street murders 18 months later. Julie has never been seen since, nor has her body been found. Her disappearance is one of Australia’s oldest, most haunting ‘cold cases’.

TRUE CRIME
When 20-year-old Matthew Leveson failed to return home after a night out clubbing in Sydney, his loved ones were worried sick. Matty was a trustworthy, warm, and caring young man who adored his friends and family, not the type of person who would just take off without a word. Suspicion soon fell on Matt’s partner, 45-year-old Michael Atkins, after it was revealed that the pair were fighting on the night of Matt’s disappearance. But was that unfortunate timing, or did Atkins have something to hide? Matty is a 10-part series narrated by Loren O’Keeffe from The Missed Foundation (formerly known as MPAN – Missing Persons Advocacy Network). Join Loren as she documents the decade-long struggle faced by Matt’s parents, Mark and Faye, who refused to give up on their son. We go behind the headlines for an exclusive insight into how the investigation unfolded, exploring the failures of law enforcement and the ongoing obstacles faced by the Levesons. At the heart of it all lies the question: how far would you go to bring your loved one home? Hosted on Acast. See acast.com/privacy for more information.
