A call has been made for a full investigation into the death of an OAP on Sunday morning.
Police are trying to trace the occupants of a white van following the death of an 83-year-old woman on the outskirts of Perth.
She was walking along the carriageway before being struck by a vehicle on the A9 between the Broxden and Inveralmond roundabouts.
Inquiries are still ongoing to establish the full circumstances after the woman was pronounced dead at the scene at around 2.25am.
A spokesman for Police Scotland confirmed they are trying to work out the last movements of the elderly woman before she was knocked down and killed.
Police have so far declined to confirm if it was being treated as a hit-and-run. It is not known how she came to be on the A9, but it is feared the woman may have become lost or disorientated and walked on to the carriageway.
Investigators now want to hear from anyone who may have spotted an elderly woman walking on her own prior to the incident.
Councillor Chris Ahern, who serves the Perth City Centre ward, said he hoped there would be a full investigation into the circumstances.
He said: “It’s particularly concerning and we need to know why a person of that age was out at that time of the morning.
“It makes you wonder if they had left a local care home nearby.
“It’s not nice to hear of an incident of this type anyway, but when you factor in that this is an elderly woman it’s particularly disturbing.
“It’s extremely concerning.
“There needs to be a full investigation into this, particularly why this woman was on the carriageway at this time.”
Anyone who may have witnessed the incident or saw a female walking in the area is asked to call Police Scotland on 101.
