A woman who died after being struck by an SUV as she and family members left a graduation ceremony at Mountain View High School Thursday night has been identified.

Dorothy Penrod, 82, was in a wheelchair, being pushed by her daughter and a nephew was walking beside her as they left the graduation of a family member just after 9:30 p.m., Capt. Adam Goldberg, spokesman for the Northwest Fire District, said in a news release.

Her nephew, 59, remains in critical condition at a local hospital, Deputy Jesus Bañuelos, spokesman for the Pima County Sheriff’s Department, said.

They were crossing from the west side of North Thornydale Road to the east side of the roadway where their car was parked just south of West Linda Vista Boulevard when they were struck by a northbound SUV, Goldberg said. The daughter pushing the wheelchair was uninjured.

Both Penrod and her nephew were taken by ambulance to a local hospital. Penrod died shortly after arriving at the emergency room. The name of the nephew has not been made public.

The driver of the SUV remained at the scene and was cooperating with investigators from the Pima County Sheriff’s Department, Goldberg said.

There were no crosswalks or lights in the area where the pedestrians were struck, he said.

The intersection of Linda Vista and Thornydale was approximately 600 feet from where the pedestrians were attempting to cross. The intersection has traffic signals that have pedestrian controls to aid students and residents in the area cross safely.
