The Sangamon County coroner has identified the man who died while working on an HVAC system at Abraham Lincoln Capital Airport Tuesday.
55-year-old Gregory Fields of Springfield sustained blunt force injuries and burns as he was making repairs to the system.
He died a short time later at Springfield Memorial Hospital. Airport officials say Fields was a contractor doing maintenance on the system, located outside on the southwest side of the terminal building, in a secure area.
There was no immediate word about how the accident happened; the State Fire Marshal is reportedly investigating the incident.
