Authorities in western Iowa’s Ida County say a man has suffocated at a rural dairy. About 6:45 last night, the Ida County Communications Center got a 9-1-1 call from the Holstein Dairy regarding a person who had been trapped in a silage pile and wasn’t breathing. Paramedics couldn’t revive the man, said to be in his early 20s, and the county medical examiner pronounced him dead. No name has been released.
