Senior Sergeant Soutar said police were calling for anyone who may have witnessed a serious crash on the Coalfields Highway at 5.21 on Thursday, May 10.
He said police believe a vehicle was driving on the wrong side of the road when it collided head-on with another car, causing extensive damage to both vehicles.
