yo dreamerish you might already have this but here u go anyway:
The Azaria Chamberlain case (1980) is probably one of the most important in recent forensic history in Australia. It was claimed by the mother (Lindy) of Azaria that her daughter had been taken from their tent at Ayers Rock by a dingo. Inspection of the Chamberlain’s car located a stain under the passenger side dashboard.
Forensic tests performed were found to be positive for the presence of blood. In conjunction with other evidence Lindy Chamberlain was sentenced to jail. It was revealed later however that the tests performed on the sample by the forensic scientist were only presumptive (initial) tests and further positive identification was not carried out. It was realised that the presumptive test also showed positive for other substances that could have been present in the outback dust. It was also claimed by the Chamberlains that if the stain was blood it could have been from an injured person whom they had recently helped.
At this time DNA testing was not available and no samples were kept. The advent of DNA testing would have positively identified if the sample was blood and also could have identified the individual whom the sample had originated from.
this dot point hasnt been asked in the hsc yet but i doubt they'll put it in. hope this helps!!!
