WARNING: This episode discusses violence against children. 12-year-old Leanne Holland went missing in September of 1991. When her horribly mutilated body was found in bushland three days later, suspicions immediately turned to one of the last people to see her alive: her older sister's boyfriend, 28-year-old Graham Stafford. While Graham denied committing the brutal crime, the evidence seemed to be overwhelming. Blood matching Leanne's rare blood type was found in his vehicle, as was a long blonde curly hair. A hammer that Graham always had by his bedside was conveniently missing. And tire tracks that were a “perfect match” to his vehicle were found at the site where Leanne’s body was dumped. The forensic evidence was a slam dunk for the jury, and Graham was imprisoned for Leanne’s murder. It was an open and shut case… until it was revealed that those perfect tire tracks weren’t so perfect, the hair ‘found’ in his car was actually contamination from the forensic lab, and Graham had an alibi for the time of the murder.
