After a public outcry, a notorious serial killer, responsible for the deaths of three individuals, has been removed from a household where they were living with two foster children and an elderly guardian.

Reginald Arthurell, who adopted the name Regina following a gender transition in 2020, moved in with the 12 and 14-year-old children. This arrangement took place a year after a lengthy supervision order, which had monitored Arthurell’s release, came to an end.

Arthurell was incarcerated for 24 years for the 1996 murder of their fiancée, Venet Mulhall, whom they brutally bludgeoned. This crime occurred while Arthurell was on parole, having previously killed their stepfather in the 1970s with a carving knife and a teenage sailor in the 1980s.

The elderly carer, whom Arthurell met at Westmead Hospital, extended an invitation for them to share her home, where she lived with the foster children.

It has come to light that the killer, now believed to be in their late 70s, was no longer under a supervision order after it expired in December 2024, and authorities did not renew it.

Alarmed by the situation, the elderly woman’s daughter contacted the police, expressing her growing concern for both her mother and the children residing in the Western Sydney residence.

On Tuesday, 2GB radio host Ben Fordham revealed heavily-armed cops had raided the home and separated the serial killer from the children. 

It comes after the elderly woman’s daughter also shared concerns that Arthurell may be brainwashing her mother into handing over her superannuation funds as well.

After learning about Arthurell’s crimes, the woman said she tried to question her mother about why she had allowed the killer to move in with her, but was dismissed and told ‘this person has changed’. 

‘I don’t know what Reginald has disclosed, I don’t know what balances and checks have been done in regards to NSW authorities allowing this person to reside with my mother,’ she told 2GB on Monday. 

‘If this person is supposed to be under community correction orders where they’re supposed to be supervised within the community, what are the details of those orders and who is making sure those orders are being followed?’

Paul Quinn, the brother of Ms Mulhall, said he last heard his sister’s killer was being supervised in a secure location on the NSW South Coast. 

‘He was released in secrecy and the whole system has failed,’ he told Fordham.

‘It’s history repeating itself, the story that I heard is the same story he told my sister. He’s targeted vulnerable women his whole life.’

Mr Quinn said it was a ‘failure of the judicial system’ that Arthurell had even been released from jail after murdering three people.

‘A serial killer should be given an automatic life sentence with no chance of release,’ he told the radio host.

The Daily Mail understands an extended supervision order for the killer, now believed to be in their late 70s, ran out in December 2024 and was not renewed by authorities

When contacted by the Daily Mail on Monday, a spokesperson for NSW Police said: ‘The living situation is not a police matter and not for police to confirm/comment on.’

It comes five years after Arthurell was forced to move out of a Yagoona retirement home after local community members learned of her real identity.

Canterbury Bankstown Mayor Khal Asfour said he didn’t want Arthurell living in his city, describing the killer as a ‘grub’.

‘Not welcome in my city,’ Asfour said.

‘I am outraged that convicted serial killer Regina Kaye, formerly known as Reginald Kenneth Arthurell, has been allowed to live in our city under a cloud of secrecy.’

Arthurell was arrested in January 2022 on sex crime allegations after they were accused of sexually touching a 55-year-old man.
