The Benton County Sheriff’s Office confirmed Suzanne Durheim’s body was recovered Tuesday afternoon about a mile downstream from where the truck was located. Durheim disappeared on her way to work in Corvallis Jan. 7. Investigators believe she veered off the road because of icy conditions that morning.
