Landowners help search for Sidney teacher's body ?

WILLISTON, N.D. (AP) — Authorities renewed calls Monday for landowners near the northern North Dakota-Montana border to look for signs of a missing Montana teacher's buried body, while documents revealed one of the two suspects in her disappearance has spent time in prison.

At a news conference Monday, authorities asked that "landowners and landowners only" help look for the body of 43-year-old Sherry Arnold, a math teacher from Sidney, Mont., who has been missing since Jan. 7 and is presumed dead.
