A sadistic rapist in prison for torturing women has admitted to murdering a 61-year-old man 25 years ago and to soliciting his brother to kill a woman. 

Graham Thomas Sales, 56, told a NSW Supreme Court hearing on Friday he killed Ronald Richard Penn, 61, a Central Coast man who vanished from his Bateau Bay home in October, 1995. 

Sales also confessed to soliciting his brother, Ross Sales, to murder his partner Jennifer Forgacs a month later, on November 21, as she headed into Wyong Local Court to take an apprehended violence order out against him. 

The then-24-year-old was blasted with bullets into her upper left shoulder, forearm and face but remarkably survived.

'Guilty, thank you,' Sales told Justice Elizabeth Fullerton, in relation to the crime against his former girlfriend, The Daily Telegraph reports. 

Sales was due to be arraigned during the hearing but was instead committed for sentence on charges of murder and solicit to murder. 

He will be sentenced on July 24. 

Mr Penn's death had remained a mystery and his body is yet to been found.   

His white Mazda van was found burnt-out in bushland in Berkeley Vale on October 27 - three days after his last confirmed sighting at Downing Centre Court where he faced a traffic offence. 

Three men including two described as Aboriginal and one caucasian were seen near the vicinity of Mr Penn’s van shortly after it was set alight about 10pm, and were later seen leaving in a red Ford laser, hatchback, or similar vehicle. 

The missing man only had a few clothes and personal belongings with him when he vanished.

His bank accounts also lay dormant and his driver's licence was never renewed, investigators said in 2015.

Sales said he murdered the former railway worker - who had loosely become his driver because he did not have a license- in The Entrance North between October 23 and October 28.

He's already serving a 31-year minimum term at Lithgow prison for his long history of horrifying and sadistic abuse against traumatised women and children during the 1980s and 1990s.

Sales was found guilty of 21 offences including raping women with household objects, forcing them to eat their dinner off the floor and hogtying them and putting them face down in the bath. 

In 2018, he was given another four years after after pleading guilty to six counts of sexual and aggravated sexual assault, kidnapping, common assault and two counts of threatening the officer in charge during a fiery outburst in the witness box.

Sales will return to court in July for a disputed facts hearing.  

Days before Mr Penn vanished, he was pulled over in his Mazda car seated alongside Sales his brother Ross Sales in Charlestown, near Newcastle, according to police records.

Police alleged at the time they were following Ms Forgacs who had finally summoned the courage to flee his violence and had escaped to a refuge.

Police believe Sales tracked her down there a few days later and unsuccessfully tried to abduct her.

An interim apprehended violence order was taken against him, and Ms Forgacs was being transferred by car to another refuge in the Hunter Valley when the three men were pulled over near New Castle, following close behind. 

Police charged Sales with breaching the interim apprehended violence order and a court date was set for November 21, 1995.  

Police believed Mr Penn was murdered before his car was found, and dumped at an unknown location and alleged the motive was to prevent him being subpoenaed and have to give evidence during the AVO proceedings. 

Ross Sales was charged with shooting Ms Forgacs but got off on the grounds of mental illness in 1996. 

Police began re-examining crime scenes related to Mr Penn's disappearance in 2014, but did not have a breakthrough until Strike Force Rankmore detectives finally managed to get Ross Sales, then 43, to confess to his involvement in both crimes.

He was charged and later convicted of being an accessory after the fact to Mr Penn’s death.
