Devin Mazac, 22, reportedly fell into the Snake River near Swan Falls Dam on Sunday night, and as of Tuesday night searchers have yet to find him.
The Ada County Sheriff’s Office released Mazac’s name Tuesday and said searchers on the Ada County side of the dam have exhausted their options, searching with boats and sonar. It is likely, a spokesman said, that Mazac’s body passed through the dam into Canyon County, and officials there are watching for him.
Mazac was reportedly fishing with two other men south of the dam Sunday. Witnesses told authorities the man initially resurfaced about 15 yards away from where he first submerged, then went under the water again without resurfacing.
