Mont. teacher disappears while running; shoe found

BILLINGS, Mont. — Hundreds of people in Montana showed up to help in the search for a Sidney High School math teacher who didn't return from a run.

The Billings Gazette reports 43-year-old Sherry Arnold was last seen at 6:30 a.m. Saturday.

More than 200 people participated in the initial search Saturday that yielded a shoe believed to belong to Arnold near one of her regular routes.

An assistant police chief says Arnold was classified as missing on Sunday.

Nearly 1,000 people turned out for Sunday's search, but authorities limited the number to a more manageable 300. In addition to law enforcement officers and National Guard troops, a helicopter, several airplanes and three dog teams also took part.
