Academy of Science president John Shine, Nobel laureates Professor Peter Doherty and Professor Elizabeth Blackburn, and former Aussie of the Year/epidemiologist Professor Fiona Stanley. They’re 3 of the 90 doctors and scientists who have put their names to a petition calling for the release of convicted child killer Kathleen Folbigg. The 53yo has maintained her innocence after being convicted in 2003 over the death of her 4 infant children between 1989 and 1999. Folbigg’s conviction was largely based on diary entries expressing her anxieties about motherhood she says were taken out of context. The top docs say evidence that at least 2 of the children carried a mutant gene creates a “strong presumption’’ that they died from natural causes. NSW Attorney-General Mark Speakman said yesterday the petition would “be given appropriate consideration”.
