Earlier this week, in an historic decision, the NSW attorney general made the extraordinary announcement that Kathleen Folbigg had been granted a pardon after 20 years in prison. In 2003, Kathleen was sentenced to thirty years for the murders of three of her children and the manslaughter of a fourth. And while she always maintained her innocence, it wasn’t until a second inquiry into Kathleen's convictions, that new scientific developments led to revelations that three of her children could have died of natural causes. As the dust settles from this week’s announcement, attention has turned to understanding the failures that put her in jail, the scientific advancements that freed her, and quashing her convictions once and for all.  THE END BITS Subscribe to Mamamia CREDITS Guest: Dr Xanthe Mallett The latest episode of her podcast, Motive & Method, saw Xanthe and her cohost interview Kathleen's best friend Tracy Chapman.
