A woman in Australia who spent 20 years in prison after being convicted of killing her four children has been released after new DNA evidence showed that all of the children, who died as infants over a 10 year period, possessed genetic mutations that could explain their deaths. In her initial conviction, there had been no physical evidence to suggest she'd killed the infants.
Kathleen Folbigg, a 55-year-old woman from New South Wales (NSW), was accused of murdering her two daughters, Sarah and Laura, and son Patrick, as well as committing manslaughter against her other son, Caleb, between 1989 and 1999. In 2003, Folbigg was sentenced to 25 years in a maximum-security prison, where she remained until her release earlier this month. Due to the nature of her alleged crimes, the media nicknamed Folbigg "Australia's worst female serial killer."
