For many military repatriation cases, identification relies on familiar tools such as DNA, dental records, and medical radiographs. When those methods work, they provide clear and decisive answers.
But some cases fall outside that framework, especially older losses where records are incomplete or biological evidence has degraded with time. That was the situation in the case of U.S. Army Sgt. Roger Duquesne, who served with A Company, 89th Medium Tank Battalion, 25th Infantry Division during the Korean War, and whose remains had been examined repeatedly over decades without a definitive identification.
