A BRISBANE woman has been jailed for killing her rapist after he threatened to harm her daughter unless she submitted to more sex, but will be eligible for parole in less than two years.

Roxanne Eka Peters, 35, fatally stabbed Grant Jason Cassar, 51, with a blow to his heart using a kitchen knife at her home in Capalaba in December 2015. Then she tied a rope around his body, including his neck, and dragged it behind her car for about a kilometre to a ditch where she hid it.

In the Brisbane Supreme Court on Monday, Peters was sentenced to nine years in jail for manslaughter and a further 18 months after she pleaded guilty to interfering with a corpse.

With time served she will be eligible for parole in June 2020. Justice David Boddice told the court Mr Cassar’s rape and humiliation of Peters, followed by the threats to harm her child, had been a “significant provocation”.

“I accept the stabbing occurred in circumstances when you were enraged by what the deceased had done to you and was threatening to do to you again,” he said.

It was, however, to Peters’ detriment that she didn’t immediately seek help after the stabbing, he said.

“Instead you set about the process of callously disposing of the deceased body,” he said.

He said Peters had shown no respect for Mr Cassar’s human dignity.

“No doubt your rage continued to affect your attitude to him,” Justice Boddice said.

Justice Boddice said Peters’ upbringing around drug users, where she was subjected to sexual abuse, had acerbated the rage she felt when Mr Cassar came to her home on the day he died.

However, Mr Cassar’s killing had been devastating for his family.

“They will never recover from his death,” he said.
