Catherine Birnie didn’t begin her life as a murderer. But once she met David Birnie, her story shifted into one of the darkest partnerships in Australian true crime. Over just five weeks in 1986, four women vanished from quiet Perth suburbs. What unfolded behind closed doors was a nightmare of manipulation, violence, and control. Catherine wasn’t just a bystander—she was his accomplice. The question is: was she driven by love, fear, or a darkness of her own?
🎧 In this episode, we explore:
• Catherine’s troubled early life and relationships
• How she met David Birnie and became bound to him
• The horrifying five-week spree known as the Moorhouse Murders
• The methods of control, abduction, and assault used against victims
• The psychology of killer couples and how power dynamics play out
• Catherine’s trial, sentence, and what became of her in prison
• Why society continues to struggle with the idea of women as predators
🧠 This isn’t just the story of a killer—it’s the story of how love, obsession, and control can become deadly.
📍 Four victims. One couple. A city forever haunted.
