When Bob Chappell vanished from his yacht in Hobart, suspicion quickly turned on his partner, Sue Neill-Fraser, an unassuming woman who soon found herself at the centre of one of Australia’s most controversial murder cases.

But behind the headlines lies a deeper story - one of forensic failure, investigative tunnel vision, and a conviction that may never have happened if all the available avenues had been investigated.

In this episode, former detective Colin McLaren unpacks the crucial DNA evidence, the overlooked clues on the yacht, and the questions raised by a mysterious yellow Ford.

This is a story about how forensics should work, and what happens when it doesn’t.

Note: Sue Neill-Fraser was found guilty by a Supreme Court jury; her appeal was dismissed, and a Coroner’s investigation, which reviewed all the available evidence, supported the findings of the criminal proceedings. Tasmania Police stand by the integrity and thoroughness of the investigation, and the efforts of the investigation team, including the forensic experts, and the prosecution of the case by the office of the DPP.

In the late 1980s and early 1990s, rugby league was a code looking to expand nationally after the success of its premier competition in Sydney. Clubs emerged in Brisbane, Newcastle, and the Gold Coast.

Rupert Murdoch's News Corporation took the growth in the sport as an indication it ought to expand even further and plotted a coup, to take the running of the code out of the hands of the establishment - the Australian Rugby League.

What followed was a war that ripped the sport apart with Murdoch on one side and the other, backed by another multi-millionaire media mogul, Kerry Packer. It was mogul against mogul, club against club, and players against players.

In this episode of Judgements we take a deep dive on how and why the war began - and how the game came back together to form what is now the National Rugby League.

Semen is the crack cocaine of the fly world, and while maggots love a corpse, flies feast on live human flesh and fluids. So, could a fly frame you for murder? And how do police differentiate fly 'artifacts' from human biological material at a crime scene?

These are all things forensic biologist, Dr Annalisa Durdle has studied. Join former Crime Insiders Forensics host Kathryn Fox as Annalisa redefines what it means to be a 'fly on the wall'.
