LITTLE ROCK (AP) — The U.S. Department of Defense says the remains of a missing Air Force captain from Arkansas have been identified and will be buried as part of a group with full military honors at Arlington National Cemetery.

The department says the remains of Capt. Virgil Meroney III of Fayetteville will be buried with those of Air Force Col. Wendell Keller of Fargo, N.D. A date for the ceremony was not announced.

Meroney and Keller were part of a crew of an F-4D Phantom II aircraft that disappeared following a mission on March 1, 1969, in Laos.

The department says the remains were found during a 17-year investigation of the area that ran from 1994 until 2011 and that they were identified with military ID cards, other circumstantial evidence and dental records.
