Emergency crews were called to a fire in the facility's basement around 5:40 a.m., according to Aurora Police Sgt. Dan Ferrelli, a department spokesman. They found a man there with "self-inflicted non-gunshot" wounds and transported him to a hospital, Ferrelli said.
The man is not an air traffic controller or FAA manager, according to an FAA source at the facility.
The source, who received a briefing from officials, said it appears the injured person is a contractor. "He is not a FAA employee,'' the source said.
A vehicle in the facility's parking lot that is believed to have been used by the man has been taped off by authorities, another source said.
As per usual, authorities wouldn't say if the fire was set.
