A 78-year-old woman was hit by a car in the 3200 block of University Avenue while crossing the street in North Park Saturday night, according to San Diego Police.
The two women who were in a Ford Focus stopped to help the victim, and witnesses, including an off-duty nurse, attempted first aid before police arrived just after 8:30 p.m.
Both the nurse and San Diego Fire-Rescue medics performed CPR, but the woman was pronounced dead at the scene.
The victim was not jaywalking, and alcohol is not believed to be a factor in the crash.
Police say the woman lived nearby.
San Diego Police Department's Traffic Devision is investigating.
