Mr Snooks had been to police in the past, concerned about Bufton’s mental health.
“She had been behaving very erratically and had been verbally and physically assaulting him for some time,” Mr Armstrong said of a December 2016 complaint.
When Mr Snooks’ former wife Carol asked him for a divorce in the weeks before he died, Bufton “got shitty” because he hadn’t suggested it, Mr Armstrong said.
Mr Snooks arrived at Bufton’s property to collect his caravan, but Bufton drove off in his car.
She used his caravan as a “way of controlling him and domineering him,” Mr Armstrong said.
The jury accepted a prosecution claim that Bufton, seeing Mr Snooks walking down the driveway in an attempt to leave on foot, deliberately ran him down.
“She is just absolutely incandescent with rage … and that explains what happens thereafter,” Mr Armstrong said.
Mr Snooks’ friend Benjamin Weston witnessed the killing, but died before the trial.
He was heard on a recorded triple-zero call accusing Bufton of murdering Mr Snooks moments after the crash.
“This bloody woman. This is f—ing murder,” he was heard saying.
“Why’d he have to run in front of me?” Bufton asked.
“He didn’t run in front of you,” Mr Weston replied.
Bufton claimed Mr Snooks had deliberately jumped in front of her car and told police she’d been doing about 20 km/h.
But experts estimated her speed at about 45 km/h.
Bufton’s barrister Tom Danos said the emergency call captured an “anguished” scream by his client.
“I would suggest to you that that is the scream of a woman who has realised what’s happened and is absolutely taken by, absolutely anguished by what had occurred,” Mr Danos said.
He argued the prosecution’s claim Bufton was “this enraged woman driving the vehicle like a maniac” was “well beyond what occurred”.
