Police are appealing to the public for help finding those responsible for the violent murders of two men and a dog in a harrowing attack at Wyndham Vale.

It’s believed as many as 10 people, who travelled to the house in a convoy of cars, were responsible for the executions at the Carmichael Drive home in the early hours of Saturday morning.

Another man was taken to hospital with life-threatening injuries.

“It does appear to be targeted, very much so,” Detective Acting Superintendent Dean Thomas from Crime Command told Neil Mitchell.
