 Authorities say a 21-year-old man whose body was found in a fish house during the eel pond festival in Walker died of accidental carbon monoxide poisoning last month. Cass County Sheriff Tom Birch released the ruling of the Ramsey County Medical Examiner's office today. Samuel Shulie of Bemidji was unresponsive when authorities responded to an emergency call for help at the festival on February 25th. He was later pronounced dead at a Park Rapids Hospital.
