The best I could find was a reference to Dennis Rader, the BTK killer, who served in Okinawa with the United States Air Force, and who is suspected of potential involvement in some unsolved murders there between 1966 and 1970.  Those crimes, however, did not fit Rader's traditional technique, so it is doubtful that he was involved.  Did you mean the United States Air Force or some other air force?  Do you have any other details you can provide?  The question is just too ambiguous for much more detail.
