The NSW attorney-general has refused to recommend a pardon for convicted child killer Kathleen Folbigg, but has recommended yet another public inquiry into the deaths of Folbigg's four children in response to a petition for her release signed last year by 90 eminent scientists citing evidence that say raises doubt over her guilt.
Folbigg was jailed in 2003 for murdering her children Patrick, Sarah and Laura, and for the manslaughter of her son Caleb.
