A 54-year-old Marshall man was killed in a one vehicle rollover accident south of Clarkfield last Wednesday, April 5. Byron Dean Iverson was pronounced dead at the scene. A passenger, Gigi Marie Alter, 53 of Cottonwood, was transported by air to a hospital in St. Cloud with non-life threatening injuries. Iverson was driving a Jeep Grand Cherokee northbound on Hwy. 59 when the vehicle left the roadway and vaulted over a driveway access. The Jeep then rolled and came to a rest on its roof. Alcohol was not a factor in the crash, and both occupants of the vehicle were wearing seat belts. The Minnesota State Patrol investigated the accident with assistance from the Yellow Medicine County Sheriff’s Office.
