The call for anyone with information about the death of Whanganui woman Fay Butler is being renewed three months after she died.
The 79-year-old's body was found near the corner of Anzac Parade and Helmore St at 1.50am on August 28.
She died from injuries consistent with being hit by a vehicle.
The case appeared on the latest episode of Police Ten 7 in the hopes of gathering new information.
Senior Sergeant Aaron Bunker said police had canvassed CCTV and identified a number of vehicles that were in the area at the time, and had spoken to all the drivers apart from one who was driving a large dark SUV.
