Roxanne Eka Peters, 35, stabbed 51-year-old Grant Cassar in the heart and penis with a kitchen knife days after he raped her.
She launched the attack at her home after Cassar threatened to harm her young daughter unless she had sex with him again, reports show.
Documents show that she repeatedly stabbed him, and said: “You don’t rape me”.
After the killing in Queensland, Australia, Peters attached Cassar’s body to her car with a rope before dragging it along the streets.
Peters was yesterday jailed for 10-and-a-half years in Brisbane after pleading guilty to manslaughter and interfering with a corpse.
However, she will be eligible for parole in less than two years – in June 2020.
