Authorities in Granite City are investigating the death of a man whose body was found at the Granite City Works of U.S. Steel early yesterday morning. Co-workers discovered 56 year old Dennis C. Courtaway's body in a carbon monoxide filled area of the mill. He was not wearing the appropriate breathing or safety gear.

A preliminary investigation indicates Courtaway, of Caseyville, entered the hazardous zone with the intentions of taking his own life. Officials say they found what could be a suicide note in one of the mill's offices.
