PULLMAN, Wash. -

Pullman Police are investigating the discovery of the body of a WSU professor found in a pond at Sunnyside Park Wednesday morning.

According to police, 51-year-old Scott Stratton, an instructor in the WSU history department, took his dog for a walk Tuesday night at 7 p.m. At 8 p.m. the dog came home alone and the family became worried and started searching for him.  

The family called police at 10:45 p.m. and police immediately started searching the area. Around 6:30 Wednesday morning the man's body was located in the pond at Sunnyside Park,

Police are preliminarily labeling the death as accidental; there was nothing suspicious found at the scene and the pond was partially frozen over leading them to believe that he could have fallen in. 

Stratton, according to police, has a history of medical problems so they are not ruling out natural causes. There were no signs of foul play and the coroner has made a preliminary classification of the death as accidental.

Stratton teaches upper division courses on the American Civil War, American Popular Culture, a senior level seminar on the 1960s counterculture era and a class on historical and legacy studies in relation to the 50th anniversary of the assassination of President John F. Kennedy.
