Overview

• Tyrone Thompson pleaded guilty to the 2022 murder of his ex-partner Mackenzie Anderson, whom he stabbed 78 times in her Mayfield, Newcastle apartment.
• Thompson was sentenced to 22 years and six months in prison, with a non-parole period of 15 years and six months, by the New South Wales Supreme Court.
• The court considered Thompson’s complex PTSD and severe personality disorder as mitigating factors but upheld his accountability for the crime.
• Anderson had sought help from domestic violence agencies and lived in fear of Thompson, who violated an apprehended violence order before the attack.
• Her mother, Tabitha Acret, condemned the sentence as inadequate and called for systemic reforms to domestic violence protections and parole oversight.
