A Holden Commodore used in the shooting murder of Queensland man Christopher Anderson could help police track down his killers.
Police say the silver 2000s model with a black bonnet was used as a getaway car after the 36-year-old father's murder at a home at Gailes, near Ipswich, on Saturday afternoon.
Detectives are appealing for anyone who has seen the car, which has black rims, not to approach but to contact them.
Police believe four men arrived at the home in the car about 4pm on Saturday and approached Mr Anderson.
They went inside before an argument started and a single gunshot was heard.
Mr Anderson chased the four men out of the house towards the Holden.
Another scuffle broke out before the father was shot in the chest.
The car was driven off and Mr Anderson died of a single gunshot wound not long after.
Police have already released images of the four men they are hunting.
