Inside The Minds Of Australia’s Worst Female Killers

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.
