A woman who spent 20 years in prison for killing her four children has had the convictions overturned by an Australian appeal court.

Kathleen Folbigg, 56, was released from prison in June after being pardoned at the New South Wales state government’s direction following new scientific evidence that her four children may have died from natural causes as she had insisted.
