Introduced by Nicholas Cowdery, former NSW Director of Public ProsecutionsKathleen Folbigg is serving a 30-year prison sentence for killing all four of her infant children.During her 2003 trial the court heard that Caleb, Patrick, Sarah and Laura were all killed by a mother who was driven to smother her children in fits of rage.Having exhausted her rights of appeal, Folbigg has her hopes pinned on the outcome of a petition seeking a judicial review of her case.Drafted by a Newcastle legal team and submitted three years ago to the NSW Attorney General's department, the petition argues amongst other things that some of the medical evidence against Folbigg during the trial was flawed.During this program we hear from Kathleen Folbigg for the first time, as she speaks out from behind bars about her conviction and the incriminating diary entries that were instrumental in securing the jury's guilty verdict.We also hear from the then NSW Director of Public Prosecutions Nicholas Cowdery, who remains firmly of the belief that the jury got it right.
