SHADOW OF DOUBT explores why the police accepted a dubious informant and why they felt no need to investigate other persons of interest or follow other leads. He doesn’t believe shock is sufficient reason to tell lies and is satisfied the police investigation was thorough and conclusive.

Detective Inspector Peter Powell who headed the investigation is convinced of Sue’s guilt. The prosecution’s case was simple: On Australia Day Sue went back to the yacht, struck Bob from behind with a wrench, returned late at night, winched his body into a dinghy, sinking Bob with a big fire extinguisher. Early the next morning the yacht was found sabotaged, sinking and there was no sign of Bob. Sue had returned to shore in the couple’s dinghy… Bob decided to keep working and stay on board overnight. On the day Bob disappeared he was working on Four Winds. No forensic evidence linked Sue to the crime scene, Four Winds, the couple’s luxury 54’ yacht moored in the Derwent River, Sandy Bay, Tasmania. There were no eye witnesses, no weapon, no plausible motive and Bob’s body has never been found.

Sue has always protested her innocence, vehemently denying any involvement in Bob’s disappearance. This is the first time someone has been jailed in Tasmania for murder based solely on circumstantial evidence and without a body. In October 2010, his partner of 18 years, Sue Neill-Fraser, was convicted of murder and jailed for 26 years, later reduced to 23 years. Set in Hobart, this documentary follows one of the most intriguing and alarming legal cases in recent Australian history.īob Chappell, radiation physicist, aged 65, was last seen alive on Australia Day, 26 January 2009.
