An autistic man lived on frogs and roots as he wandered for weeks in the remote Escalante Desert of southern Utah until being rescued, emaciated but alive.

William Martin LaFever, 28, of Colorado Springs, Colo., told rescuers that in addition to the bits of food he scavenged, including a few frogs he caught, he drank water from the Escalante River while attempting to walk from Boulder, Utah, to Page, Ariz., a distance of approximately 90 miles or more by the route he appeared to be taking.
