TUCSON, Ariz. -- Authorities have released the name of a wheelchair-bound woman who was fatally struck by a vehicle while leaving a high school graduation in Tucson.
Northwest Fire District officials say 82-year-old Dorothy Penrod died Thursday night, shortly after arriving at University of Arizona Medical Center.
The woman's 59-year-old nephew also was struck and was listed Friday in extremely critical condition.
Fire District officials say a group of people was crossed a street after watching a relative graduate from Mountain View High School.
They say the group was crossing the road at a spot without a crosswalk or lights and about 600 feet from a lit intersection with traffic signals.
The driver of the vehicle involved in the accident was said to be cooperating with Pima County sheriff's investigators.
