Whanganui police say they've identified several vehicles of interest after an elderly woman died in a suspected hit-and-run last month.
The body of 79-year-old Fay Butler was found near the intersection of Anzac Parade and Helmore St in the early hours of Wednesday, August 28.
Police said her injuries were consistent with a vehicle collision.
Senior Sergeant Aaron Bunker said police inquiries and a review of CCTV footage had led to the identification of several vehicles of interest.
"We're looking for the driver of a grey four-door sedan with a black middle trim that was in the Anzac Parade and Helmore St area at the time," he said.
