The body of Koby Clark, 21, of Bozeman, Montana, was discovered Thursday six miles east of Lowell in the Selway River, the Idaho County Sheriff's Office said.
Mahopac High School graduates Raymond Ferrieri, 24, and his 21-year-old brother, Jesse, are still unaccounted for, the Sheriff's Office said.
The men went missing May 21 while on a bear hunting trip when the SUV they were riding in overturned in the Selway River which is located in the backwoods of Idaho.
Two of the men were able to escape uninjured and have since returned to their homes in Georgia, said Idaho County Sheriff Doug Giddings.
The families of the missing, along with local connections, have been searching the river for the men since the incident. They told the Statesman they intend to continue searching until all have been found.
