Australian serial killer Reginald Arthurell is leading a new life as a woman after his prison release and has allegedly made threats against his female victim's family.
Radio station 2GB has revealed photos of the violent outback murderer, now aged 74, dressed in a series of women's wigs posing for the camera.
The photos were allegedly posted on a transgender community friendship page by Arthurell, who now goes by the name of Regina and is living in western Sydney.
He has posed in three different coloured wigs, including one in a dark brown bob which he has used as his signature image, with the words, "Hi, I'm Regina".
NSW Police are also investigating a claim Arthurell had vowed to "take out" the family of his victim, Venet Raylee Mulhall.
Corrective Services NSW referred police to an allegation by a concerned transgender community member that Arthurell allegedly contacted via the Facebook page.
He had allegedly said he would act against the family and Corrective Services once his parole had ended and he was no longer wearing a tracking anklet.
Corrective Services said it was "aware that an associate of a 74-year-old parolee has contacted the registered victim of the offender (and) … immediately referred" the matter to NSW Police.
Arthurell was released on parole last November after serving 24 years in prison for bludgeoning Venet Mulhall, then his fiancee, to death in 1997 with a piece of wood.
His parole will end on May 24, but an Interim Supervision Order (ISO) taken out by the NSW Attorney-General Mark Speakman will immediately come into force.
This means Arthurell will still have to wear a tracking anklet and may be restricted in changing his appearance.
His 16 parole conditions until May 24 do not prevent a change of appearance such as presenting himself as a woman.
However, he must apply in advance to Community Corrections NSW for every move he makes outside his residence, meaning he would have had to apply to enter any shops.
Former rodeo worker's history of killing
Arthurell, a former rodeo worker, was an outback drifter when he committed his first two killings four decades ago.
The tall, powerful, self-styled "cowboy" had two manslaughter convictions when he met vulnerable and devoutly religious Venet Raylee Mulhall in the 1980s.
When Arthurell was 28, he had killed his stepfather, Thomas Thornton, 49, with a carving knife and then gone on the run.
Working at rodeos in Queensland and the Northern Territory, Arthurell met another man and together in 1981 they robbed and killed 19-year-old sailor, Ross Browning.
Browning's mutilated body was found in scrub just 35km east of Tennant Creek.
NT Police described the killing as "the most vicious" they had investigated, but two murder trials were aborted and both men pleaded guilty to reduced charges of manslaughter.
Mulhall started writing to Arthurell in 1986 when he was serving time in Darwin Correctional Centre for Browning's killing.
A Prison Fellowship Christian, Mulhall was five years older than Arthurell and visited him in prison, where he was baptised and convinced her – and authorities – he had found God and reformed.
Mulhall had suffered a broken marriage and had been left with her face permanently paralysed and disfigured by an operation to remove a tumour next to her brain.
Arthurell, who had proposed to Mulhall, was released into the care of his new fiancee in April 1991.
He was still on parole in February 1997 when he murdered her at the Coonabarabran home in central western NSW Mulhall had bought to forge their new life together.
Her brother, Paul Quinn, found Venet's decomposing body at the home.
Inside, he discovered on his sister's camera images of Arthurell – who had fled in Venet's car – cross-dressing in his fiancee's clothing.
Arthurell's full sentence for murdering Mulhall expires on May 24.
The NSW Attorney-General's ISO will stand until July when the Supreme Court will consider whether to impose an Extended Supervision order of up to five years.
CSNSW said electronic monitoring of Arthurell while still on parole meant if he diverted from his pre-approved schedule of movements "an alert is immediately sent back to the monitoring room".
"The offender must also report weekly to Community Corrections, have home visits and can be subject to unannounced home visits.
"The welfare and safety of victims of crime is of the utmost importance.
"Community Corrections will advise the State Parole Authority if they have any concerns about the offender's behaviour.
"The SPA is empowered to revoke parole if there is a breach of conditions or there are concerns for community safety."
Paul Quinn said Arthurell should have been sentenced to life without parole.
"These people commit crimes that are so outrageous that they exclude themselves from society," Quinn told 2GB.
The first thing the judge should actually consider is how do you reintegrate these people back into society.
"You can't. They should stay in prison for the rest of their life."
