Tyrone Thompson, aged 25, is set to be sentenced today at the Newcastle Supreme Court for the brutal murder of his ex-girlfriend, Mackenzie Anderson, in March 2022. This gruesome act occurred just 16 days after Thompson was released on parole for prior domestic violence offences against Anderson. The shocking incident unfolded when Thompson, armed with two kitchen knives, assaulted the 21-year-old woman in her Mayfield apartment, inflicting a staggering 78 stab wounds during a horrifying two-minute attack.
Initially slated to face a murder trial, Thompson instead pleaded guilty last month, expressing remorse in a letter to the court. He claimed to have loved Anderson and asserted that he never intended to harm her. He described a struggle for control over the knife during an argument, leaving him feeling overwhelmed when he sustained a hand injury. However, prosecutors pointed out elements of victim-blaming in his letter, while the defence noted that despite his expressed remorse, there was little insight into his violent behaviour.
Eyewitness accounts described a male friend of Anderson’s witnessing the murder through a gap in a blocked door, seeing Thompson attack her without uttering a word. When police arrived, they found Anderson lying on the floor with multiple stab wounds, including a broken knife handle resting on her chest.
Thompson’s mental health was also discussed in court, with testimonies suggesting he was suffering from complex post-traumatic stress disorder and a severe personality disorder but was not psychotic at the time of the stabbing. His legal representation has previously indicated that these mental health issues should be considered when evaluating his moral culpability for the crime.
As the court prepares for the sentencing, the implications of Thompson’s actions and the tragic loss of Mackenzie Anderson remain at the forefront of this harrowing case, prompting a wider conversation about domestic violence and mental health.
