(MARLETTE) -- A snowmobiler reported missing from the Marlette area was found dead in Tuscola County Thursday evening by a volunteer fireman from the Marlette Fire Department. Authorities say the family of 32-year old Donald Robbins III reported him missing Thursday morning. No one had heard from him since 10 p.m. Monday. A search was conducted in an area between Marlette and property owned by the family in the Kingston area. Police say it appears that Robbins failed to negotiate a large drainage ditch, which resulted in the fatal crash. The accident remains under investigation.
