Authorities are searching for a missing Ohio woman who disappeared while she was hiking in the Great Smoky Mountain National Park on the North Carolina-Tennessee border. Mitzie Sue “Susan” Clements, 53, was with her daughter Tuesday when they briefly split up. Clements has been missing ever since.

The daughter hiked slightly ahead of her mother, but when she turned around to rejoin Clements she was gone.

As of yesterday afternoon, searchers have not discovered any clues or hints to her whereabouts. About 125 people from some 30 different agencies are searching areas including the tops and sides of several mountains.

Crews are using K-9 units, helicopters and drones to aid the search.

The area has a very rugged terrain and thick vegetation, making search very methodical.

Clements was last seen wearing a green zip-up sweater, a clear rain poncho, black pants over black leggings and white tennis shoes.
