LEWISTON, Idaho -

Two fishermen recently reported seeing what they thought was a body in the Snake River west of Clarkston, Wash., prompting a search that resumed Tuesday.

Aston County Sheriff's Capt. Dan Hally says divers were checking an area that was difficult to examine in previous attempts.

Officials have said they were searching for a possible body in the river related to missing persons cases in the Lewiston-Clarkston Valley, but did not tie it to a specific case.

Hally said the Nez Perce County sheriff's office received a tip about a month ago about a possible body in the river. Sheriff's boats searched the Idaho side of the water. The Asotin County search has focused on the area from the confluence of the Snake and Clearwater rivers to the Port of Wilma.
