The man, who has not been identified, drove up to the building around 11 p.m. Thursday. A sheriff's spokeswoman says the injured man was taken by helicopter to a Delray Beach hospital for treatment. He was expected to survive.
The man told authorities he was driving near the Palm Beach International Airport about a half hour earlier when an unknown man approached his vehicle, opened his passenger-side door and began firing, hitting him mostly in the torso.
The victim said he did not know the person who shot him.
