STERLING, Colo. (AP) — The Logan County Sheriff’s Office has released the name of a 40-year-old man whose body was pulled from the North Sterling Reservoir over the weekend.

Wednesday the man has been identified as Tracy D. Senyard. Lt. Joe McBride says the Sterling man was involved in some sort of a swimming accident Sunday. The circumstances leading to the death have not been released.

Sterling Fire Chief Kurt Vogel told the Denver Post the victim did not register any vital signs when he was pulled from the water about an hour and a half after authorities were called to the reservoir in northeastern Colorado.
