Authorities Say Missing Montana Teacher Is Dead HELENA, Mont. - A Montana math teacher who disappeared last weekend when she left her house for a run is dead, and the FBI said Friday it had one man in custody and was questioning another in connection with her disappearance. No further information was immediately available, although a news conference was scheduled for Friday afternoon. "I think we are starting to find some closure in the whole deal," Sidney Mayor Bret Smelser said. The news is not good, and as far as I know we don't have a body yet. FBI Special Agent in Charge David J. Johnson, of Salt Lake City, said a tip from the public led to the two men. The FBI hasn't confirmed Arnold's death. Authorities had been investigating the possibility Arnold was abducted. Karen Arnold Truax of St. Paul, Minn., the daughter of Sherry Arnold's husband, Gary, told The Billings Gazette the family wants some privacy and "time to process what has happened." We appreciate everything that everyone did to help us in this search. We are so heartbroken that this is the outcome," Truax said. We just sincerely appreciate all the love and support that continues to come from the community.
