A judicial inquiry into Kathleen Folbigg's convictions for killing her four children has been told the NSW Director of Public Prosecutions (DPP) accepts new evidence points to the possibility of reasonable doubt.
Folbigg, 55, who has been called Australia's worst female serial killer, has five years remaining of a 25-year sentence, after being convicted in 2003 of three counts of murder and one of manslaughter.
