Accused Claremont Serial Killer Confesses To Rapes

Accused Claremont serial killer Bradley Robert Edwards has pleaded guilty to five of eight charges against him, including twice raping a 17-year-old girl, but maintains he didn't commit the murders.

The former Telstra worker is accused of slaying Sarah Spiers, 18, Jane Rimmer, 23, and Ciara Glennon, 27, who were all last seen on the affluent Perth suburb's entertainment strip in 1996 and 1997.

The 50-year-old was also facing allegations he attacked an 18-year-old woman as she slept in her Huntingdale home in 1988 and twice raped the girl at Karrakatta cemetery in 1995.

But on Monday, at the final directions hearing before a nine-month judge-alone trial slated to begin next month, Edwards pleaded guilty to break-in, deprivation of liberty and sexual assault charges.

Prosecutor Carmel Barbagallo said the development would greatly reduce the length of the trial.

Defence counsel Paul Yovich said his preference was for the trial to begin as planned on November 18.

Supreme Court of WA Justice Stephen Hall said he was inclined to proceed as scheduled.

The remains of Ms Glennon, a lawyer, and Ms Rimmer, a child care worker, were discovered in bushland at opposite ends of Perth weeks after their murders, both with some form of neck injury.

But the body of Ms Spiers, a secretary, has never been found.
