VALE, S.D. (AP) — Searchers have found the body of a missing fisherman in western South Dakota.

The body of 67-year-old Glen Shay of Vale was found Tuesday in the Belle Fourche River.

The Butte County Sheriff’s Office says Shay was last seen Monday afternoon walking with two fishing poles and a folding camp stool to a fishing hole north of Vale.

Sheriff Fred Lamphere says a search began when Shay did not return.

Searchers found Shay’s body in the water. Lamphere says Shay likely slipped on the river bank and drowned.

The Rapid City Journal reports the sheriff said the river banks are unstable because of high water.
