“There were only two people on this earth who knew what it felt like to lose Caleb, Patrick, Sarah and Laura,” she said.
“My condolences go to the loved ones Craig leaves behind.”
Kathleen Folbigg was acquitted in the NSW Court of Criminal Appeal over the children’s deaths in December after multiple inquiries, the latest of which heard there was reasonable doubt about her guilt after previously undiscovered genetic variants were identified in the children.
Craig Folbigg testified against her in the 2003 trial that led to her spending two decades in prison.
