Convicted killer Tyrone Thompson’s behaviour was considered so erratic that six people were granted formal protection from him in his first four years of adulthood – and before he stabbed his ex-girlfriend 78 times in less than three minutes because she rejected him.

But the now 25-year-old’s impulsive fury did not dissipate after being thrown in jail on remand as he awaited his fate for brutally murdering Mackenzie Anderson at Mayfield in 2022, with prison authorities classifying him as being one of the state’s most high-risk inmates by transferring him to Goulburn’s Supermax after bashing at least two guards among a litany of other reported incidents behind bars.

The full extent of Thompson’s behaviour can now be revealed after he pleaded guilty in NSW Supreme Court this week to Ms Anderson’s horrific murder, the details of which have shocked the nation.

Among those who were granted apprehended violence orders were both his parents and four young women – including Ms Anderson after Thompson was arrested and later jailed for assault, stalking and property damage offences committed against his former partner five months before she was killed.

Within 16 days of being released on parole for those offences, the then 22-year-old used at least two knives to murder the young Newcastle mother in her own home before seeking sympathy for cuts to his fingers as emergency services personnel frantically tried to save Ms Anderson’s life.

The frenzied attack occurred despite a fresh condition on the apprehended domestic violence order being placed on Thompson before he was granted parole – that he not contact or approach Ms Anderson for five years.

The added non-contact condition – which needs to be specifically granted by a magistrate along with the mandatory conditions of not assaulting, threatening, harassing, stalking or intimidating the protected person – was also placed on three other ADVOs naming Thompson as the defendant.

Each of those involved young women.

The two AVOs placed on Thompson relating to his parents included conditions that he not go near their home, work and other specific places.

On each of the six ADVOs, the orders were made without admissions from Thompson about any allegations made against him.

All the ADVOs were granted between early 2018 and his arrest for allegedly bashing his dad two weeks before the murder of Ms Anderson.

In January 2022 – three months after he was jailed for assaulting and intimidating Ms Anderson and two months before he murdered her – Thompson was convicted on two counts of contravening an apprehended violence order.

Thompson had committed those two contraventions the previous year.

Other than the convictions being placed, no further penalty was handed to Thompson.

In 2020, Thompson was charged with one count each of contravening an AVO, assault occasioning actual bodily harm and intentionally choke a person without their consent.

In December 2022 – nine months after Thompson committed the murder – those charges were withdrawn by prosecutors and formally dismissed in Gosford Local Court.

He was convicted of bashing his father the day after he was released on parole before those convictions were quashed on appeal.

Thompson will also face a sentencing hearing in May for two counts of assaulting a law enforcement officer (not police) after incidents involving prison guards in jail.

One count of destroying or damaging property – where Thompson allegedly smashed up an audio visual link suite inside prison after a remote court appearance– is still before the courts.

Thompson will face a two-day sentence hearing for the murder in the NSW Supreme Court later this month.
