A man gunned down in a Melbourne driveway last August may have been followed by his killer, police say.
Ferntree Gully man Zabi Ezedyar, 26, was found with several gunshot wounds to his upper body at a Narre Warren home on August 16.
He was treated by paramedics but died at the scene.
Police on Wednesday released CCTV footage of a Holden CRV seen driving in the area shortly before Mr Ezedyar was murdered and believe it may be linked to the shooting.
It shows the car travelling behind the victim's car, shortly before he arrived at the property where he was shot, and it's believed the vehicle was last seen heading south along Kurrajong Road.
"We're very keen to know why the Honda CRV was in the area at the time of the incident and whether it is linked to those responsible for Zabi's death," homicide squad Detective Inspector Tim Day said in a statement.
He said police were also looking at whether a white Toyota Corolla, possibly a 2014-15 model, is linked to the shooting or was used by any of the offenders in the lead up.
Det Insp Day will address the media alongside Mr Ezedyar's family on Wednesday morning.
