Kathleen Folbigg spent 20 years in an Australian prison accused of the deaths of her four children. New scientific evidence has now led to her release and an unconditional pardon.

A woman once branded "Australia's worst female serial killer" has been pardoned after new evidence suggested she did not kill her four infant children. Kathleen Folbigg spent 20 years in prison after a jury found she killed sons Caleb and Patrick and daughters Sarah and Laura over a decade.

Kathleen Folbigg has been pardoned and released after two decades in prison over the deaths of her four children, following a decision of the New South Wales attorney general, Michael Daley.

Kathleen Folbigg, 55, was unconditionally pardoned Monday for the killing of her four infant children between 1989 and 1999. She was sentenced to 40 years in prison in 2003, with the term later reduced on appeal to 30 years with a minimum of 25 years.

Kathleen Folbigg, 55, received an unconditional pardon from New South Wales Gov. Margaret Beazley and was released from a prison in the city of Grafton.

The pardon was seen as the quickest way of getting Kathleen Folbigg out of prison, and a final report from the second inquiry into her guilt could recommend the state Court of Appeals quash her convictions. Folbigg, now 55, was released from a prison in Grafton, New South Wales state, following an unconditional pardon by Gov. Margaret Beazley.
