On November 1, 1996, Joint Task Force-Full Accounting (JTF-FA, now DPAA) identified the remains of Major John Robert Hagan, missing from the Vietnam War.

Major Hagan joined the U.S. Marine Corps from Georgia and was a member of the Headquarters Company, Headquarters Battalion, 3rd Marine Division. On May 6, 1969, he was the observer aboard an O-1G Bird Dog (bureau number 156682) on a visual reconnaissance mission down Route 9 in Vietnam to the border with Laos. The O-1G went down at some point during the mission, and Maj Hagan died in the incident. Search efforts were unable to locate the Bird Dog's crash site or its crew. In 1996, a joint U.S. and Vietnamese search team excavated a crash site associated with Maj Hagan's O-1G, recovering human remains. Later that year, forensic analysis identified some of the recovered remains as those of Maj Hagan.

Major Hagan is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
