An Omaha man is dead after being run over by his brother’s motorcycle near Council Bluffs. The Iowa State Patrol says 23-year-old David Splittgerber died after undergoing surgery following the crash that occurred at around 7:40 P.M. Wednesday on Interstate 29.

Authorities say motorcycles driven by Splittgerber and his 20-year-old brother Andrew, also of Omaha, were merging onto I-29 northbound from Exit 52 on the city’s southwest side, when David Splittgerber lost control of his 2007 Harley Davidson motorcycle. As the cycle slid on the pavement, it was hit by on the rear by his brother’s 2008 Harley. Moments later, David Splittgerber was run over by his brother’s bike.

Both cycles then left the road. David was taken by Council Bluffs Fire and Rescue to a trauma center in Omaha (Creighton University Medical Center) where he later died from his injuries. Andrew Splittgerber was apparently not injured in the crash, which remains under investigation.
