Mother dubbed ‘Australia’s worst female serial killer’ pardoned after scientific break in case

Kathleen Folbigg was pardoned and released from jail by the New South Wales Attorney-General Tuesday after spending 20 years behind bars for killing her four children. Folbigg was serving a 30-year prison sentence for the murder of three of her children and the manslaughter of another son; the children died suddenly between 1989 to 1999 and were between 19 days to 19 months old. New scientific evidence revealed her children carried a rare genetic disease that established "reasonable doubt" as to her guilt for all four deaths. “Today is a victory for science, and especially truth,” Folbigg said in a video statement after her release.
