A Nebraska man died as the result of rollover accident this (Saturday) morning, in Pottawattamie County. The Iowa State Patrol says 57-year old Thomas Vogtman, of Omaha, was flown by LifeNet to Creighton University Hospital in Omaha where he was pronounced dead. The Patrol says Vogtman was driving a 2004 Toyota RAV 4 eastbound on Interstate 80 about 5-miles northeast of Council Bluffs at around 11:10-a.m., when for reasons unknown, the vehicle veered left into the median and came back out before rolling across I-80 and coming to rest in the northeast ditch. Vogtman, who was not wearing a seat belt, was ejected from the vehicle.
