Major Crash Investigators have released CCTV vision of two cars who drove past the scene of a fatal hit-and-run crash in Golden Bay.
Father-of-nine Mathew Neary was found lying in the northbound lane of Mandurah Road with significant injuries on Sunday, November 22 and could not be saved.
Police believe the occupants of the vehicles may have information that could assist with the investigation.
The vision is facing west over Mandurah Road and Anstey Drive intersections at about 2:39am.
The occupants of those vehicles are urged to contact Crime Stoppers by calling 1800 333 000 or by making a report online at crimestopperswa.com.au.
Investigators also appeal to anyone with dashcam of the area, or who were travelling north on the Kwinana Freeway, near Paganoni Road or travelling on Mandurah Road between Paganoni Road and Safety Bay Road, between 2:00am and 2:45am to contact Crime Stoppers, even if they saw nothing of any significance.
