Authorities are investigating an accident at an Illinois chemical plant that's left an Iowa man dead.
Forty-six-year-old Timothy Shields of Cedar Falls, Iowa, died Wednesday at a Joliet hospital.
The Will County Sheriff's office says Shields was finishing demolition work at the Oiltanking plant in Channahon when a 10-foot section of rebar hit him in the forehead, under his hard hat.
An autopsy has cited the accident as his cause of death.
The Occupational Health and Safety Administration and the sheriff's office are investigating.
Channahon is about 40 miles southwest of Chicago.
