The Defense POW/MIA Accounting Agency (DPAA) announced today that Army Tech Sgt. Matthew L. McKeon, 25, of Euclid, California, killed during World War II, was accounted for Jan. 12, 2023.In November 1944, McKeon was assigned to Company K, 3rd Battalion, 12th Infantry Regiment, 4th Infantry Division. His unit was engaged in battle with German forces near Hürtgen, Germany, in the Hürtgen Forest, when he was reported killed in action on Nov. 9. His remains could not be recovered during the battle.Following the end of the war, the American Graves Registration Command was tasked with investigating and recovering missing American personnel in Europe. They conducted several investigations in the Hürtgen area between 1946 and 1950 but were unable to identify McKeon’s remains. He was declared nonrecoverable on Dec. 15, 1950.While studying unresolved American losses in the Hürtgen area, a DPAA historian determined that one set of unidentified remains, designated X-4458 Neuville, recovered near the town of Hürtgen in 1946 possibly belonged to a service member missing from combat in November 1944, such as McKeon. The remains, which had been buried in Ardennes American Cemetery in 1950, were disinterred in June 2021 and sent to the DPAA laboratory at Offutt Air Force Base, Nebraska, for identification.To identify McKeon’s remains, scientists from DPAA used dental and anthropological analysis. Additionally, scientists from the Armed Forces Medical Examiner System used mitochondrial DNA (mtDNA), Y chromosome (Y-STR), and autosomal DNA (auSTR) analysis.McKeon’s name is recorded on the Walls of the Missing at Netherlands American Cemetery, an American Battle Monuments Commission site in Margraten, Netherlands, along with the others still missing from World War II. A rosette will be placed next to his name to indicate he has been accounted for.McKeon will be buried in San Diego, California on date yet to be determined.For family and funeral information, contact the Army Casualty Office at (800) 892-2490.DPAA is grateful to the American Battle Monuments Commission and to the U.S. Army Regional Mortuary-Europe/Africa for their partnership in this mission.For additional information on the Defense Department’s mission to account for Americans who went missing while serving our country, visit the DPAA website at www.dpaa.mil, find us on social media at www.facebook.com/dodpaa or https://www.linkedin.com/company/defense-pow-mia-accounting-agency.
