Authorities said scattered human remains have been found of all three missing Dalton fishermen who got too close to the Nickajack Dam and were swept into the floodgates.
Two of the bodies were near the dam and a third was downriver near Scottsboro, Ala.
Divers also found some personal items that belonged to the missing men.
The boat capsized last Saturday night. Two brothers, Hildebrando Hureta-Hernandez, 14, and Norberto Hureta-Hernandez, 26, were rescued about two miles downstream.
A medical examiner initially studied the remains found near the dam and said he believes they are human.
The three missing men were Hilavio Soniga, 64, Trancito Garcia, 32, and Angel Ocampo, 49.
