A 90-year-old woman from the town of Knierim was killed in a two-vehicle accident in rural Calhoun County Thursday afternoon. The Iowa State Patrol identified the victim as Cleo Ballstadt.

Reportedly, a northbound 2007 Chevrolet Trailblazer driven by Ballstadt was stopped at the stop sign at the junction of U.S Highway 20 and Calhoun County Road N-65 east of Rockwell City. The Ballstadt SUV entered the intersection into the path of an eastbound 2007 Peterbilt semi driven by William Cullen of Fonda. The semi struck the SUV in the driver’s door.

The impact sent the semi into the median and westbound lanes of traffic, landing into the north ditch and ending up in a farm field.

Ballstadt was pronounced dead at the accident scene. Cullen escaped injury.
