PHOENIX -- Authorities say a 73-year-old woman who allegedly caused two fatal accidents is in critical condition at a Phoenix-area hospital.
Maricopa County sheriff's spokesman Deputy Joaquin Enriquez says the woman was driving her SUV near Bush Highway and Usery Pass Road in the Tonto National Forest on Wednesday morning when she hit and killed a female bicyclist.
The woman continued driving and witnesses followed her to Ellsworth and McKellips roads. That's where she ran a red light and crashed into another vehicle.
The driver of that car, a 53-year-old man, was killed.
The 73-year-old woman is expected to survive. Her name was not immediately released.
Deputies are trying to determine if she was impaired or has a medical condition.
