New clues in the Claremont serial killings appear to have emerged - detailing the type of car driven by the murderer.
According to The Subiaco Post, police believe the killer used a mid-1990s white Holden Commodore VS series 1 to abduct and kill at least two of his victims.
They have linked fibres found on Jane Rimmer's body to the upholstery of a car matching that description.
The newspaper also reports the killer had some link to screen-printing and had a way of "printing coloured words and patterns on fabric such as T-shirts".
After years of apparent inaction on the unsolved case, these are the latest clues to be revealed by the Post, which identified a link between the killer and the rape of a woman in Karrakatta Cemetery in October.
The paper said police have forensic evidence linking Ciara Glennon's killer with a rapist who abducted a 17-year-old woman from a Claremont street then raped her in the cemetery back in 1995.
The young woman had left Club Bay View shortly after midnight and was walking to a friend's house when she was abducted, taken to the cemetery, raped and released.
The Post also reports that new evidence shows this victim was tied up with washing line, not telephone wire as previously reported, and that the line was "impregnated with material used in screen printing".
Sarah Spiers, 18, went missing from outside a Claremont nightclub in January 1996; Ms Rimmer, 23, was abducted from Claremont in June 1996 and her body found in bushland south of Perth that August.
Ms Glennon, 27, disappeared in March 1997. Her body was found in bushland north of Perth 19 days after she was last seen in Claremont.
The Post reported that police, who said at the time the Karrakatta attack was not linked, had now changed their view after finding a forensic link in 2009 and a 12-member squad was working on the case.
WA Police issued a statement that seemed to indicate the revelations were true and important to their overall investigation.
"Maintaining the operational integrity of the Macro investigation is paramount if WA Police is to bring the offender, or offenders, to justice," it said.
"Therefore operational outcomes must be prioritised over media and public interest.
"Media reports on an active investigation can seriously jeopardise the investigation and negatively impact future prosecutions. To protect the ongoing investigation WA Police is not in a position to make any further comment.
"We are mindful of the public interest in this matter, however we need to balance this with the interests of the investigation."
