This week's Australian Story concludes the two-part program looking into the 1991 murder of 12-year-old Leanne Holland and the subsequent conviction of Graham Stafford. Despite the compelling body of evidence presented against Graham Stafford during his trial, a broad-based group of professionals has joined forces to clear his name. The group, led by former Queensland detective Graeme Crowley, believes that critical evidence used to convict Graham Stafford was seriously flawed. In this week's episode, support for Graham Stafford's case emerges from surprising quarters. Prison guards who knew him in jail speak publicly for the first time in a show of support. The jury foreman from the original trial outlines why he is now convinced of Graham Stafford's innocence. A forensic scientist whose evidence helped convict Graham Stafford now declares that she believes Graham Stafford was wrongly convicted. And a forensic entomologist dismisses a key piece of evidence in Graham Stafford's conviction - the presence of a single maggot in the boot of his car - as an "impossible" scenario. Ex-policeman Graeme Crowley also reveals the results of his 15-year investigation into who he believes killed Leanne Holland.
