Authorities Sunday identified the 91-year-old woman killed Friday in a crash in Clairemont Mesa.

Doris Lucille Guffin was driving her Toyota Camry south on Mt. Abernathy Avenue around 11:15 a.m. when she was struck by a car headed eastbound on Balboa Avenue.

Investigators determined Guffin was driving “at a high rate of speed” and ran a red light at the intersection of Mt. Abernathy and Balboa, according to the San Diego County Medical Examiner’s Office.

Her car hit a light pole and was torn into two parts.

Police and fire personnel responded, and Guffin was pronounced dead at the scene.

The other motorist involved in the crash, a 32-year-old woman, suffered minor injuries, including cuts and scratches, Officer Tony Martinez of the San Diego Police Department said Friday.
