The state patrol says a trooper tried to pull a car over for a traffic stop on Interstate 80 eastbound near the I-280 interchange.
The car refused to stop and led the trooper on a chase.
The suspect took a Davenport exit, lost control and collided with another car.
The suspect’s car rolled and the driver was killed. She’s identified as 31-year-old Kathryn Burkhead of Donahue.
Troopers say the driver of the other car, an Iowa City woman, had her life saved by her seatbelt, though she was injured.
