Sarah MacDiarmid (born 15 November 1966) was a 23-year-old Scottish-Australian woman who disappeared from Kananook railway station in Melbourne, Victoria, Australia on 11 July 1990. She is presumed murdered, although no trace of her body has ever been found. Disappearance MacDiarmid, who emigrated with her family in 1987 from the Scottish Highlands to Australia, had been playing tennis after work with two friends at what was then known as Flinders Park in Batman Avenue, East Melbourne, before walking to Richmond station, where they found that they had just missed a Frankston line train. They caught a train to Caulfield, then changed to a Frankston service. MacDiarmid's friends disembarked this train at Bonbeach while she remained, continuing on to Kananook station where her vehicle was parked. She was last seen alighting the train and heading for the poorly lit car park at approximately 10:20 p.m. Investigation Police suspected that MacDiarmid had been assaulted, based on bloodstains found beside her red 1978 Honda Civic abandoned in the station car park, and drag marks leading into the bushes. A cigarette lighter belonging to MacDiarmid was discovered on the ground, but no trace of her was ever found. Later, witnesses said MacDiarmid got off the train and crossed the footbridge to the car park, where some people heard a woman shouting, "Give me back my keys!". An extensive 21-day air, sea and land search, involving more than 250 police, produced no results. In May 2006, an inquest held by coroner Ian West, found MacDiarmid "had met her death as a result of foul play but the exact circumstances were unknown". An initial State Government reward of $50,000 was increased after an additional $75,000 was offered by an anonymous benefactor. That was increased to $1 million in 2004, and remains current. In 2011, convicted Australian serial killer Paul Denyer was interviewed by police and denied any involvement in MacDiarmid's disappearance. Denyer stated to the interviewer, Detective Ron Iddles that he was "sick of being accused of murder", and later wrote to Iddles, thanking him for informing the public of him not being involved in the matter. In May 2014, News Corp Australia claimed police investigators considered convicted Australian serial killer Bandali Debs to be a suspect in the case. Fairfax Media quoted a "senior police source" who said "it was 'common practice' for homicide investigators to examine links between unsolved murders and known offenders". A
