Bob Chappell, Sue's long time partner, disappears from his boat in Hobart. DNA of a girl named Meaghan Vass is found on the boat. Vass is known to associate with criminals who used to ransack boats in the harbour. Yet this clearly crucial evidence is somehow dismissed, and Sue Neil-Fraser is convicted on the basis of.. well.. very little circumstantial "evidence". Vass has now admitted to being on the boat when Bob was killed, and that Sue Neil-Fraser was not there. Yet Neil-Fraser remains in prison.
Evidence wise, this is a very straight forward case. It does not take Sherlock Holmes to see the importance of the DNA evidence. Neil-Fraser is clearly innocent. But the police are stuck with their tunnel vision and the legal system is more concerned with protecting their image than with justice.
