A Spanish official says a 39-year-old man arrested on suspicion of involvement in the disappearance of an American woman who went missing while walking a pilgrimage route has led police to a body on his rural property in northwest Spain.

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.

Interior Minister Jorge Fernandez Diaz is meeting Saturday with police and military who were involved in the search for Thiem.
