Homicide squad detectives are still piecing together the circumstances of a crash in Melbourne's outer east in which a young man was found dead from a suspected gunshot wound.
Emergencies services were called to what was believed to be a fatal crash involving a beige Nissan Pulsar sedan and a cement truck on Mount Dandenong Road in Croydon on Tuesday, only to discover that the passenger of the car had been shot.
The homicide squad was promptly called in.
Police will reveal only that the dead man was aged in his 20s and was in the passenger seat of the car.
"We don't believe the actual shooting incident was connected to the accident at the intersection," Detective Senior Sergeant Stephen McIntyre said.
"We believe the gunshot was sustained somewhere other than this location."
The 22-year-old driver of the car suffered minor injuries in the crash.
He is assisting police with their inquiries, but no charges have been laid.
Police are trying to piece together the car's movements before the collision.
Investigators are urging anyone who saw the Nissan sedan, registration ROP683, between Monday and Tuesday to contact Crime Stoppers on 1800 333 000.
