Kathleen Folbigg pardoned after 20 years for killing her four babies.

Kathleen Folbigg, who was convicted of killing her four children and serving 20 years in prison, has been pardoned by the New South Wales Attorney General after an inquiry found "reasonable doubt" as to her guilt for all four deaths. Folbigg was convicted in 2003 on three counts of murder and one of manslaughter, but there was no physical evidence that she had caused their deaths. The jury relied on the prosecution's suggestion that the chances of four babies from one family dying from natural causes before the age of two were so low as to be compared to pigs flying.
