A collision between a car and a semi Sunday afternoon resulted in the death of a Carroll County woman. The Iowa State Patrol says 83-year old Irene Kathryn Klahn, of Carroll died, when her 2002 Buick Century crossed the center line of Highway 71 and collided with a semi tractor trailer. The accident happened about 3 miles north of Exira, as Klahn was traveling north on 71. The Patrol says the driver of the semi, 42-year old Michael Miller, of Buckeye, Az, swerved onto the shoulder of the road to avoid the crash, but the car hit the semi neat its fuel tank. The car then spun around and ended up on the east shoulder. The semi came to rest in the west ditch. Klahn, who was wearing a seatbelt, died at the Audubon County Memorial Hospital. The accident remains under investigation.
