Victoria Police are yet to track down a motorist involved in a suspected hit and run in the state's east.
A man believed to be in his 60s was found lying in a ditch on Waterloo Road, Trafalgar, on Sunday morning.
Paramedics were called to the scene and declared the man dead.
Detective Sergeant Peter Romanis of the Major Collision Investigation Unit said authorities had little doubt a car was involved.
"We say that because of the debris – including fragments of glass, plastic and indicator lights – that was found at the scene," he said.
"That was strewn for quite some distance, so we are fairly certain that a vehicle was involved."
Given the isolated location of the incident and a lack of CCTV footage, police say they are struggling to identify the victim or the driver.

'Come forward and speak'
The victim was last seen walking through Trafalgar at about 7:00 pm on Saturday night.
Police said there was every possibility he had been lying on the side of the road for several hours before being spotted by a passer-by.
Police have issued a public plea for assistance and are calling on the driver or any witnesses to come forward.
"Imagine if it was your friend, your family," Sergeant Romanis said.
"What would you expect someone to do in that circumstance?
"I know what the right thing to do is, and that's to come forward and speak with us."

Victim may have been homeless
The victim was found wearing a black tracksuit top, a white chequered shirt, black trackpants and no shoes.
Following what had been a cold and wet few days, Sergeant Romanis believed this could be a sign the man was homeless.
"The weather was pretty horrible on Saturday," he said.
"It's a concern for him that he was wearing no shoes, and it may be indicative that that he had been sleeping rough."
Forensic specialists are now combing through dozens of pieces of evidence to try and establish the make and model of the vehicle.
Residents of Trafalgar and surrounding communities are being urged to keep an eye out for a vehicle with significant damage.
"We're expecting that damage to be on the front passenger side — there may be damage to the headlight," Sergeant Romanis said.
There have been a total of 25 pedestrian fatalities in Victoria in 2024, up from 16 this time last year.
