AP reported that federal workplace safety officials in southwestern Illinois are investigating the death of a steel worker who apparently fell through a roof.

The Madison County coroner's office said that Mr Jeffrey Pace died at a hospital after an accident at Alton Steel. Investigators with the Occupational Safety & Health Administration are looking into the incident.

Police said that Mr Pace was working on a new roof portion when he fell about 60 feet to the ground.

An autopsy was planned to determine whether anything such as a medical condition contributed to the accident.
