Bega schoolgirl killer Leslie Camilleri has pleaded guilty to the murder of a teenager who disappeared from her Melbourne home 20 years ago.
Prue disappeared from her Glenroy home on February 2, 1992.
Her body has never been found.
Camilleri, 43, pleaded guilty to murdering the 13-year-old in the Victorian Supreme Court on Monday.
Police conducted a three-day search for her remains near Flat Rock Creek, north of the town of Cann River in far East Gippsland, in February.
But the search was called off after officers found nothing.
The site is near where the bodies of schoolgirls Lauren Barry and Nichole Collins were found in 1997.
The girls were kidnapped by Camilleri and an accomplice in Bega, NSW, and driven across the border to the isolated region where they were repeatedly raped and killed.
Camilleri is serving life without parole for those murders.
