After spending 20 years in prison, an Australian mother who was convicted of killing her four young children has been granted a pardon, according to authorities. The case of Kathleen Folbigg, who was labeled “Australia’s worst female serial killer,” took a dramatic turn following an inquiry that challenged the previous convictions. In 2003, Folbigg was found guilty of murdering three of her children and causing the manslaughter of another. However, a petition signed by numerous scientists in 2021 presented new forensic evidence suggesting that the deaths could be attributed to rare genetic mutations or congenital abnormalities. Following a year-long inquiry, the New South Wales Attorney-General, Michael Daley, announced that there was now “reasonable doubt” surrounding the convictions and that Folbigg had been pardoned. The inquiry led by retired judge Tom Bathurst revealed medical conditions that could explain three of the deaths, including a rare genetic mutation in two of the children and a potential underlying neurogenic condition in another. Bathurst also stated that he could not disregard the fact that Folbigg had been a caring mother to her children. The Australian Academy of Science, which played a role in initiating the inquiry, expressed relief at the outcome, perceiving it as a step towards justice for Folbigg.
