IDAHO FALLS, Idaho (AP) - Authorities believe a medical condition may have played a role in the death of a Vermont man who drowned while fishing a trout stream in eastern Idaho.
The Fremont County Sheriff's Office said 70-year-old Robert Pressley Evans of Killington, Vt., died Sunday morning. Investigators say he was alone at the time, fishing a section of the Henry's Fork of the Snake River.
Evans was pronounced dead at the scene.
Authorities believe an unidentified medical condition was a factor in his death.
The drowning is the first in eastern Idaho this year.
