8-16-15 (Tenstrike, MN)  --  Beltrami County authorities are still looking for a missing man in the Tenstrike area north of Bemidji.  Nineteen-year-old Darren Chock called 9-1-1 Tuesday afternoon to report that he was emotionally distressed.  A large-scale search began in a wooded area Tuesday and continued Wednesday morning until severe thunderstorms postponed the effort.  Chock is white, five-foot-six inches tall, weighs about 165 pounds and has hazel eyes and dark blond hair.  Investigators say Chock does not have a vehicle but may be armed.  Anyone who sees him is asked to contact the Beltrami County Sheriff's Office.
