Jamestown  (NDHP) On January 21, shortly after 7 pm, Gregory Anderson, 63, Little Falls, MN, was driving a 2004 Peterbilt loaded with cattle from a Jamestown feedlot to Aberdeen. Shortly after beginning the trip, approximately 2.5 miles east of Jamestown on Old Highway 10, Anderson suffered a sudden medical condition. The condition caused him to drift off the highway and into a field. A short time later, two motorists approached the truck, found the driver unconscious and called 911. A Stutsman County Deputy, NDHP Troopers, and Jamestown Ambulance responders arrived minutes later. Anderson was transported to the Jamestown Regional Medical Center where he was declared deceased. There was no damage to the truck or load. The incident remains under investigation by the North Dakota Highway Patrol.
