The Murder of Rachel McLean

Oxford, April 1991. English student Rachel McLean vanishes from the house she shares with friends, mid-way through a weekend of exam revision. Her tutor calls 999. Her boyfriend — a British-born New Zealander named John Tanner — tells detectives he last saw her at Oxford station chatting to a mystery stranger. He gives a detailed description. He fronts a televised appeal. He plays the grieving boyfriend to perfection. But police soon discover that the ‘stranger’ is a figment of his imagination. And, by the time they arrest Tanner, Rachel’s body has been found under the floorboards of her home. Forensic psychologist Kerry Daynes traces a case that changed the way Britain looked at controlling relationships, and asks what Tanner's later New Zealand conviction — for serious violence against another partner — reveal about a man who has always insisted he simply 'snapped' as a result of provocation. Listen now to The Profiler with Kerry Daynes.
