A native of
Cincinnati, Ohio, Lupo delivered newspapers before being
drafted in October 1917, along with hundreds of thousands of other young American men after Congress declared war on Germany at the behest of President
Woodrow Wilson. With only a fifth-grade education, he arrived in France in March 1918, and was assigned to the
18th Infantry Regiment of the
U.S. 1st Infantry Division. On July 20, his battalion took part in a French-led attack on a German-held
salient near Soissons. Lupo was killed in combat on that same day and was hastily buried on the battlefield, in the same grave with another U.S. soldier. In 2003, French
archaeologists discovered the remains of both men. After the identification of his remains, Lupo's living next-of-kin contacted by the Army was his niece, Rachel Kleisinger. The soldier found along with Lupo remains unidentified. Lupo was buried with full honors at
Arlington National Cemetery in September 2006. The location of the grave is section 66, grave number 7489. Lupo's name appears on the Tablets of the Missing at the Aisne-Marne American Cemetery in Belleau, France. He was awarded the
Purple Heart and the
World War I Victory Medal with three Battle Clasps. A rosette is added to his name on the Tablets of the Missing, indicating that his remains were identified and accounted for. == Advances in forensic technology ==
