A regional government spokesman says Miguel Angel Munoz took investigators to his small farm near the Camino de Santiago, also called St. James Way, after being arrested Friday in Asturias, 200 kilometers (124 miles) to the north.
Experts are trying to determine if the corpse is that of Denise Thiem, 41, of Arizona who was last seen April 5 in the nearby town of Astorga.
