Missing: Belinda Peisley (pictured) vanished from her home in Katoomba, in the Blue Mountains in 1998
A missing woman's muddy clothes have been found in her home 20 years after she mysteriously vanished.
Belinda Peisley, 19, disappeared from her home in Katoomba in the Blue Mountains in 1998.
Police suspect the mother-of-two was murdered but have never found her body.
On Monday detectives released images of lingerie, a skirt and a dress which they found during a forensic search of her home in December.
Officers said analysis of the clothes has given them new lines of inquiry for the cold case.
The last person known to have seen Belinda alive was a nurse at Blue Mountains Hospital on September 26, 1998.
Two years before, the teenager had inherited a large amount of money and bought a weatherboard home in Katoomba's Trow Avenue.
But by the time she disappeared Ms Peisley was a drug addict, in considerable debt and the only money coming into her account was welfare payments.
A coroner said in 2013 there was 'considerable suspicion' three people had some knowledge or involvement in her suspected death - but no-one has ever been charged.
Last month it was revealed Belinda's ex-boyfriend had been been heard referring to a 'dead chick' in a phone call to his mother in 2011.

A summary of the tapped phone call was presented to an inquest into Ms Peisley's death in 2012 and 2013.
In the conversation, obtained by ABC podcast Unravel, the ex-boyfriend, who cannot be named for legal reasons, is thought to be talking about his brother.
'If he says something silly about the dead chick from Sydney he'll sink me,' he said.
The telephone call was part of the brief of evidence handed to the inquest, but was not explicitly mentioned at the hearing.
Neither the ex-boyfriend nor his parents were questioned on the matter
