Lionel John Patea had a history of violence and criminal offending and had been in and out of prison in the years leading up to the brutal murder of his ex-partner Tara Brown.
Court documents obtained by the Herald reveal that he breached protection orders - meant to keep Brown safe - three times before he murdered the Kiwi-born mum-of-one. But when she sought another one before her dreadful death, police turned her down.
Brown, 24, died on September 9, 2015, after Patea ran her car off the road on a Gold Coast street and, as she lay trapped, beat her to death with a metal fire hydrant cover.
The pair had been in a relationship on and off since 2011 and had a young daughter together.
Brown had left Patea again just days before her murder.

Patea was sentenced to life in prison yesterday.
He was set to go on trial in the Brisbane Supreme Court but changed his plea at the last minute and was sentenced by Justice Debra Mullins.
After sentencing, Justice Mullins gave the Herald access to Patea's court file, including his list of previous offences.
The list reveals that Patea, a former member of the Bandidos gang, had spent time in prison in the past.
His criminal offending started in 2009 and carried on even after he was remanded in custody on the charge of murdering Brown.
Patea was charged with assault occasioning bodily harm and failure to appear in court. No conviction was recorded, but he was fined $300 and ordered to pay $400 compensation and, according to court documents, "not further punished".
Patea was charged with two counts of receiving tainted property and possessing/acquiring restricted items. Again, no conviction was recorded but he was fined $1400.
He escaped conviction again when he was charged with public nuisance. He was fined $200.
Patea was convicted on one charge of unlawful possession of suspected stolen property and fined $600.
His offending started to escalate and he was convicted on two counts of wilful damage, breaching an order and unauthorised dealing with shop goods. He was fined $1500 in total and put on probation for 18 months.
Patea was charged with unlawful use of a motor vehicle but again, escaped conviction and walked away from court with just a fine. This time he was ordered to pay $500.
He notched up another conviction for breaching the probation order put in place in December 2010. He was also fined another $500.
Now in an on-off relationship with Brown, Patea carried on offending. On July 17 he was convicted on two counts of breaching an order and one of using a carriage service to make a threat to kill. He was given a suspended sentence of one month in prison. He spent six days in custody after his arrest, which was considered time served.
Patea was back in court on July 30 for breaching a protection order, understood to be against Tara Brown. Her then-partner was convicted of the breach and sentenced to one month in prison. His suspended sentence handed down on July 17 was invoked and he served that concurrently.
Only out of prison a couple of months, Patea was back in court. He'd breached his 2010 probation order again and there were two charges of wilful damage and one of breaching a domestic violence order. He was convicted on all charges, sentenced to two months in prison and fined $750. The same day Patea was also sentenced to six months in jail for an earlier fraud. In December 2011 he was charged with dishonestly gaining a benefit and ordered to pay restitution of $1640.
On remand and awaiting trial for the murder of Brown, Patea offended again. He was sentenced to 18 months in prison after he admitted assaulting another inmate at the Arthur Gorrie Correctional Centre in Queensland. He was originally charged with grievous bodily harm but pleaded guilty to the lesser charge when he appeared in the Brisbane Magistrates' Court. Patea threw "very hot" water at the other prisoner after the man called him a derogatory name and challenged him to a fight. Patea was convicted and sentenced to prison time that he had to serve concurrently to being on remand for Brown's murder.
