Authorities are repeating a request for landowners in Eastern Montana and western North Dakota to search their properties for signs of missing Montana teacher and alleged kidnapping victim Sherry Arnold.
Arnold disappeared Jan. 7 from Sidney and is presumed dead. Her body has not been recovered.
The FBI is asking property owners to check for disturbed soil and matted grass on vacant farmsteads or along shelter belts, which are lines of trees that protect farmland from wind.
The agency says Arnold's body may be buried in a shelter belt with mature or rotted trees.
Two men charged in Montana with aggravated kidnapping in the case are being held in Williston, N.D. Extradition hearings are scheduled next month.
Property owners who discover something unusual are asked to call (701) 774-9191.
