LAS VEGAS - Illusionist Roy Horn has checked into a German rehabilitation facility, 18 months after a near-fatal tiger mauling during a performance left him partially paralyzed. “Siegfried and I are thrilled to return to our home country and excited with the programs set forth by the great doctors and staff at the world-class Leonardis Clinic,” Horn said in a statement Friday. ... Horn has said he fainted during the performance and the tiger was trying to help him. Animal experts have disputed that theory.
