A victim of a paedophile who raped and killed a schoolgirl has pleaded for her abuser not to be released from prison.
Michael Guider, 66, is currently serving a 17-year prison sentence for a string of sex offences after nine-year-old Samantha Knight vanished without a trace in 1986.
He also pleaded guilty to manslaughter but has never revealed the location of Samantha's body.
Guider is eligible for parole later this month, to the horror of another of his victims.
Chantelle, 28, was abused in the same year Samantha disappeared in her home in the Sydney suburb of Manly, Australia.
Chantelle told Australia's 60 Minutes television programme: "I know that he drugged us to make it easier for him to film things with us,' Chantelle recalled to 60 Minutes.
"He would get us naked and … he'd (touch) and get us to touch each other.
"Mr Guider is a predator. He is a repeat offender. The only reason he has not offended in the last 20 years is because he was locked safely behind bars."

Guider was already serving a 16-year prison sentence for 60 sex offence charges against children when he inadvertently confessed to killing Samantha to fellow inmate Frank Soonius.
Guider claims he never meant to kill Samantha and had been drugging her so he could sexually abuse her before finding her dead in his living room.
He then disposed of the body and has added to the agony Samantha's grieving parents by refusing to admit where he put the body.
