TOMBSTONE, Ariz. (AP) - Authorities say a woman was killed after her vehicle rolled over in Cochise County.

Sheriff's deputies say the accident happened Friday morning on Charleston Road.

Sheriff's spokeswoman Carol Capas says the vehicle veered off the road and the driver overcompensated, leading to a rollover.

The car came to rest upside down on a barbed wire fence.

Capas says several bystanders tried to assist 33-year-old Janna Todd, of Whetstone.

Tombstone firefighters then arrived and administered life-saving measures but Todd was unresponsive.

She was later pronounced dead at a hospital.

The crash remains under investigation.
