The FBI and local officials say the ground search for a missing high school teacher has been suspended but law enforcement will continue to pursue leads in the case.

Sidney Mayor Bret Smelser said Wednesday's decision follows an "exhaustive" search for 43-year-old Sherry Arnold in the eastern Montana town and surrounding areas. Hundreds of residents, police, firefighters and others participated.

The popular high school math teacher was last seen Saturday, when she left her home for a pre-dawn run. Authorities are investigating the possibility she was abducted.

FBI spokeswoman Deborah Bertram says law enforcement personnel will be redirected to other parts of the investigation. She says the agency cannot discuss any evidence in the case.

Anyone with information in the case is asked to call a (406) 433-4027.
