One person was killed Wednesday afternoon in Jasper County, after a pickup collided with a car, which then struck a pedestrian. The Iowa State Patrol says 24-year old Steven G. Hall, of Atlantic, was driving a 2012 Dodge Ram truck westbound on Interstate 80 about two-miles east of Mitchellville, when he ran into the back of a 2002 Dodge Intrepid, driven by 29-year old Kathleen Eckert, of Newton. Following the impact, Eckert’s car hit 23-year old Adam J. Baumert, of Des Moines, who was on the road removing debris. Baumert died at the scene. The accident, which happened at around 1:05-p.m., remains under investigation.
