From 1986-1989, unidentified human remains were turned over to the United States from the Socialist Republic of Vietnam (S.R.V.) in several different instances. None of the remains were identified given the limits of the technology of the time.
In 1993, a joint U.S.-S.R.V. team, led by the Joint POW/MIA Accounting Command (JPAC), conducted investigations in Quang Nam-Da Nang, and Thua Thien-Hue Provinces. They interviewed a local Vietnamese citizen who supplied remains and an identification tag bearing Barnes' name, which he claimed to have recovered from an aircraft crash site.
In 1999, another joint U.S.-S.R.V. team interviewed additional Vietnamese citizens about the crash and they were led to the crash site. In 2000, a joint U.S.-S.R.V. team excavated the site and recovered human remains and material evidence.
Scientists from the JPAC and the Armed Forces DNA Identification Laboratory used circumstantial evidence, and forensic identification tools such as mitochondrial DNA -- which matched that of Barnes' sister -- in the identification of the remains.
