Officials have released the name of the man accused of causing a charter bus accident that injured two people near Waterloo on Sunday. The Iowa State Patrol has identified the person as 22-year-old Jamin Kreighbaum of Burlington, Wisconsin. He’s in the Black Hawk County Jail on 25-thousand dollars bond, charged with willful injury. Officials say Kreighbaum interfered with the operation of the charter bus, as it traveled northbound on Interstate-380 in Black Hawk County. He was one of eight passengers on the Burlington Trailways bus that was heading to Waterloo. Court records say Kreighbaum grabbed the steering wheel. The bus swerved across the median and struck a southbound sport utility vehicle broadside, slightly injuring a Cedar Rapids woman and her one-year-old daughter. Investigators are still trying to determine why Kreighbaum grabbed the steering wheel.
