Authorities had been searching for Susan Casey, who was last seen on April 12. Her body was found Tuesday near Fallon, about nine miles northeast of Terry. Anderson says authorities have switched from a missing-person investigation to a suspicious-death investigation, and will have no further comment.

Casey's ex-husband, Walter Larson, has been charged with violating an order of protection Casey had filed against him. Court records say he made 44 calls to her phone in the days before she disappeared. He has pleaded not guilty in Justice Court in Dawson County.

Anderson hasn't commented on whether he believes Larson is connected to Casey's disappearance.
