Delay in Claremont killer court case

The man charged over two murders in Perth's infamous Claremont serial killer case and sex attacks on two other women has had his next court appearance scheduled for this week pushed back to February.

Bradley Robert Edwards faces eight charges including the murders of 23-year-old child care worker Jane Rimmer in June 1996 and 27-year-old lawyer Ciara Glennon in March 1997 after nights out.

Ms Rimmer's body was discovered in Wellard in August 1996, while Ms Glennon's body was found in bushland in Eglington in April 1997.

Edwards, 48, is also accused of abducting a 17-year-old girl in February 1995 as she walked through Rowe Park in Claremont and raping her in degrading and humiliating circumstances.

The Kewdale man is further charged with indecently assaulting an 18-year-old woman during a break-in at a Huntingdale home in February 1988.

Edwards, who is yet to enter a plea, was scheduled to appear in Stirling Gardens Magistrates Court on Wednesday, following a seven-month adjournment.

But the date has been vacated and he will instead be due back in court on February 28 for a committal mention.

The investigation into the suspected murder of 18-year-old secretary Sarah Spiers, who disappeared in 1996 and is believed to have been the first victim, is ongoing.

The case, dubbed Operation Macro, has gripped WA for decades and is believed to be Australia's longest-running and most expensive police investigation.
