SAN TAN VALLEY, Ariz. -- A man suffered fatal injuries after he was ejected from his SUV in a single-vehicle rollover crash in the Pinal County community of San Tan Valley.
The Pinal County Sheriff's Office said 68-year-old Keith William Swenson of San Tan Valley died in Monday's crash.
Authorities said it doesn't appear that Swenson was impaired by alcohol or drugs but say he may have suffered from a medical condition.
An autopsy will determine his cause of death.
The sheriff's office said Swenson drifted onto the road's shoulder and tried unsuccessfully to regain control of his SUV, but overcorrected and crashed.
He was not wearing a seat belt.
