A driver shot by a North Carolina trooper and deputy investigating a crash on the interstate has died.

The State Bureau of Investigation confirmed Tina Medlin's death Tuesday, three days after he was shot by her wrecked SUV on Interstate 40 near Benson.

A dozen people called 911 to report the crash. Several said they could see the driver had a gun and two said the SUV passed them earlier going around 100 mph (160 kph).

The Highway Patrol says the officers found Medlin lying in the road holding a gun Saturday morning and she fired at them before the trooper and the Johnston County deputy fired back.

Medlin, of Raleigh, was in her early 50s.

The officers are on administrative leave as state agents investigate.
