YANKTON COUNTY — A motorcyclist from Irene suffered fatal injuries March 12 in a two-vehicle crash 4 miles north and 3 miles west of Volin.

Preliminary crash information indicates Gordon J. Sorensen, the 65-year-old male driver of a 2006 Harley Davidson motorcycle, was traveling east on 301st Street near 446th Avenue behind a semi tractor/trailer. A septic tanker truck, driven by Donald E. Robinson, 54, of Yankton was traveling the same direction and was in front of the semi. The septic tanker truck slowed down to turn north into a field. Sorensen attempted to pass the semi and struck the side of the septic tanker truck as it was turning into the field. Sorensen was thrown from his motorcycle and died at the scene as a result of his injuries. He was not wearing a helmet.
