Homicide Squad detectives have released CCTV footage as they continue their investigation into the suspicious death of a man in Warnbro.
The 70-year-old man was found dead at his home on Okehampton Road around 5pm on Thursday, June 1.
His death was only reported to the Major Crime Division after a post-mortem examination determined the man's injuries were consistent with "suspicious circumstances".
Detectives have since released CCTV of a number of vehicles who drove down Okehampton Road around 2.50pm on June 1.
Police believe the occupants of the vehicles may have seen a tall unknown male wearing dark clothing in the area, who they believe may be able to assist with the investigation.
If you believe you may be the driver of one of these vehicles, have dashcam from the area around the above time, or any information, you are urged to contact Crime Stoppers on 1800 333 000 or online at www.crimestopperswa.com.au
