Mandurah detectives need help identifying a person believed to have met with the Barragup man alleged to have fired a gunshot at a Pinjarra home on Monday.
A 51-year-old Barragup man was charged in relation to the incident after being arrested on Tuesday.
But, Mandurah Detective Senior Sergeant Trevor Troy said another person of interest could help with the investigation.
The man was driving a bright blue Ford Sedan when he met with the accused prior to the Hampton Road incident at 6am, he said.
Senior Sergeant Troy said both the driver and the alleged gunman, driving a white Ford Territory Station Sedan, fled Pinjarra following the incident.
The bright blue Ford Sedan was found at a Barragup property and forensically inspected, but the driver of the vehicle is unknown.
We don’t know if they played a part, we do know both vehicles fled Pinjarra to Barragup, after the incident.Mandurah Detective Senior Sergeant Trevor Troy
“We don’t know if they played a part, we do know both vehicles fled Pinjarra to Barragup, after the incident,” Senior Sergeant Troy said.
“We are asking anyone with dashcam or CCTV footage between 5.30am and 6.30am to contact police.
“Or if anyone saw a bright blue Ford Sedan.”
The 51-year-old Barragup man was charged with committing an unlawful act with the intent to harm or endanger the life, health or safety of a person and discharging a firearm.
The man will appear before Perth Magistrates Court today.
