In 2003, Kathleen Folbigg was found guilty for the deaths of four of her children, and sentenced to 25 years in prison. All her children died as infants, and Kathleen has always maintained her innocence. But in the eyes of the law, she is Australia’s worst female serial killer. But now, almost two decades on, 151 scientists are petitioning for Kathleen Folbigg’s release. They have found a gene mutation in two of Kathleen’s children and believe they died of natural causes.

In this podcast Jane Hansen looks into the Kathleen Folbigg case. She tries to find out who Kathleen really is. Why have three of her best friends stood by her for all these years, despite her guilty verdict? We will give you insights into the history of her case, and then follow the inquiry into the new genetic discovery that could prove her innocence.
