A western Iowa man died in a work-related accident last night. The Carroll County man died in an accident at a corn processing plant. At about 8:40 last night, the Carroll County Sheriff’s office got a call that there’d been an accident at the Iowa Corn Processors Plant west of Glidden. Investigators believe 43-year-old Edward King of rural Glidden slipped and fell off the top of a railroad car at the plant. King was taken to a hospital in Carroll, where he was pronounced dead.
