Police identified her as 82-year-old Elsie "Alice" Stefani. An autopsy was scheduled for today, the Sonoma County coroner's office said.
The Saint Helena woman was walking east in the north crosswalk of Main Street and Fulton Road around 5:50 p.m. Thursday. Drivers on Fulton Road stopped to wait for her but a Toyota Rav4 turning north from Madrona Drive did not yield and struck Stefani from behind, trapping her beneath the vehicle, police said.
The Saint Helena Fire Department and Piner's Ambulance Service responded. Stefani died at 6:58 p.m., according to the coroner's office.
Police have not identified the driver, who was not issued a citation. The incident is under investigation, Cpl. Ramon Joval said. There is no indication alcohol was involved.
It was the second pedestrian fatality in the North Bay in two days. Michelle Cordova, 15, of Santa Rosa, was killed when she was struck by a car in a crosswalk on West College Avenue in Santa Rosa on Wednesday evening.
