Kathleen Folbigg pardoned after serving 20 years for infant deaths.

Kathleen Folbigg, an Australian woman who spent 20 years in prison after being convicted of killing her four children, has been pardoned after an inquiry found "reasonable doubt" as to whether the children had been killed. New science has emerged, including rare mutations in the DNA of Folbigg and her daughters that can cause sudden death in infancy and childhood, leading to doubts about her conviction. Dozens of scientists, including two Nobel laureates, signed a petition urging the governor of New South Wales to pardon Folbigg, arguing that she was "wrongfully incarcerated."
