Rodney Thomas Clarke was sentenced to serve out the rest of his life in a jail cell after climbing through the bedroom window of Deborah Keegan’s Tregear home, before he sexually assaulted and murdered the nine-year-old in cold blood.

Deborah’s sister, Sarah, was pretending to be asleep in the same bedroom during the murderous attack, before their mother found the nine-year-old dead in her bed the next morning.

However, a 2005 Supreme Court Judgement granted Clarke the possibility of parole, which was approved by the NSW State Parole Authority boss James Wood on November 13, clearing him to walk free from prison on Thursday.

The Daily Telegraph can reveal the NSW Government made attempts to block the child killer’s parole, arguing he needed to undertake further programs under the guidance of Corrective Services NSW.

Deborah Keegan’s father, Brian, also made a heartfelt plea to the NSW State Parole Authority.

However, the Serious Offenders Review Council argued the now 59-year-old was no longer a risk to the public.

“He continues to demonstrate his ability to reintegrate, and there is nothing to suggest he poses a risk to the public,” the SORC argued.

Clarke had previously been approved for more than 550 day release visits throughout the community, under a pilot program by Corrective Services, which saw him frequent local supermarkets and other public locations in an effort to reintegrate the child killer.

Clarke will experience “24/7 monitoring for the rest of his life” while also being managed by a specialised case officer.

The Daily Telegraph can confirm the child killer will also be banned from a raft of locations across NSW, including the local government areas of Shellharbour, Campbelltown, Hills Shire, Inner West and Parramatta, while also restricted from being in the company of a minor.

He will also be ordered to attend a specialist facility run by CSNSW regularly.

A notification from the State Parole Authority confirmed Clarke would see “stringent” ongoing supervision by Community Corrections and “compliance with a robust management plan”.

“His conditional release includes a ban on any contact with minors under 16 and the victim’s family, no alcohol use, exclusion zones, continued psychological treatment, regular reporting to authorities and monitoring by child protection officers,” the statement said.

“Once released, he will live in a CSNSW run facility and staffed by CSNSW, ensuring immediate intervention if any breach occurs.

“We recognise the profound impact on the victim’s family and extend our deepest sympathies for their loss,” the Authority said.

“This decision has been carefully made, based on all the available evidence and reflects the Authority’s commitment to community safety.”

A CSNSW spokeswoman told The Daily Telegraph community corrections officers “stand ready to enforce the parole conditions imposed by the independent NSW State Parole Authority”.

“Breaches of conditions are taken seriously and can include return to custody,” she said. “The prospective release of an offender can be extremely distressing for the loved ones of victims.

We acknowledge the ongoing pain and trauma experienced by victims and their families, and our thoughts remain with them at this time.”

Victim’s advocate Howard Brown told The Daily Telegraph the release of Clarke was “abhorrent”.

“People like Clarke have tortured not only the victim, but also their families, in the crimes they have committed,” he said. “It doesn’t matter how long they have served, it still reopens the wounds of decades earlier.”

In the 2005 proceedings, Justice Peter Hidden upheld Clarke’s life sentence, however, he ordered that the convicted child killer become eligible for parole in 2015.

The Supreme Court Judge described the murder as “a most distressing and appalling attack” on the nine-year-old girl.

The Supreme Court heard the rapist and killer had enrolled in prison programs for sex offenders.
