Two men and a woman who lured her former lover to a site where he was run over and repeatedly shot have been sentenced to life in prison for the murder.
Tamara Kathleen Broadbent, Gary David Young and Damien Paul Kosick were each sentenced on Tuesday in the West Australian Supreme Court to life in prison.
Broadbent and Young must serve at least 24 years behind bars before being eligible for parole, while Kosick must serve 22 years.
A third man, Kym Steven Foster, was sentenced to eight years in prison for manslaughter.
The four offenders murdered father-of-two David Blenkinsopp in March 2012.
Earlier, during sentencing submissions, a victim impact statement from Mr Blenkinsopp’s wife was read to the court in which she described her difficulty in explaining to the children that their father was dead.
The trial heard Mr Blenkinsopp, who was bipolar and a drug user, was having an affair with Broadbent in 2011, but their relationship was often violent.
By February 2012, she began dating Foster and took out a restraining order on her former lover, which he then broke, the court heard.
On March 4, Broadbent, Foster, Kosick and Young went on a drug and alcohol binge while Mr Blenkinsopp did the same elsewhere, after which he was lured to his death, prosecutors said.
The four accused confronted an unarmed Mr Blenkinsopp and shot him twice in the torso and once in the leg with a rifle.
He was also run over before being buried.
Broadbent fired at least one more shot at the bush grave.
