A Wanneroo father "did not stand a chance" when he was lured into an ambush by his former lover and confronted by three men intent on eliminating him, a Supreme Court jury has been told.
Tamara Kathleen Broadbent, Kym Steven Foster, Gary David Young and Damien Paul Kosick went on trial in the Supreme Court this morning, defending allegations they murdered 30-year-old David Blenkinsopp in March 2012.
Mr Blenkinsopp had been shot at least four times and was hit by a car before he was buried in a bush grave in Pinjar, the court was told.
In his opening address to the jury, prosecutor Bruno Fiannaca said Ms Broadbent and Mr Blenkinsopp had had an affair and it was because of the relationship that he was killed.
The jury was told the pair's relationship had been turbulent and despite a restraining order, they had continued to see one another.
He told the jury that the four accused, fuelled by alcohol and drugs, had to decided that to end what they perceived as Mr Blenkinsopp's harassment and abuse of Ms Broadbent, they had to end his life.
Mr Fiannaca alleged their worlds collided in the early hours of March 4, 2012, with Ms Broadbent deciding she had had enough of him and the four accused, who were socialising and drinking, became a "simmering cauldron of anger against Mr Blenkinsopp".
He told the jury that it would be alleged Ms Broadbent - who by this stage had begun seeing Mr Foster - lured her former lover into an ambush and he "simply didn't stand a chance" when he was later confronted by three men intent on "eliminating him".
Mr Fiannaca said Mr Blenkinsopp was shot at least three times and hit by a car before he was put into the back of the vehicle and taken to the Gnangarra pinelands where the four accused dug a "grave" using a shovel they had taken from Mr Kosick's house.
He said one more shot was fired at Mr Blenkinsopp's head and after he was buried, Ms Broadbent fired two more shots into the sand "in a final act of defiance to signify she was rid of him".
The trial continues.
