Kathleen Folbigg has spent two decades locked up over the deaths of her four children, in maximum security prisons, largely confined to a cell for her own safety, and regarded as a result of her convictions as one of Australia’s most heinous serial killers.  Ms Folbigg has always maintained her innocence. The case could well be one of the gravest miscarriages of justice this country has seen - a mother not only facing the tragedy of losing her four children, but being wrongly punished for their deaths. 

Her latest petition for pardon has been signed by scores of prominent scientists and medical professionals, who have concluded that “the scientific and medical evidence … creates a strong presumption that the Folbigg children died of natural causes”.

In this episode the Wigs discuss the case with special guest Dr Robert Cavanagh, Ms Folbigg’s barrister.
