"COLLEVILLE-SUR-MER, France — The gray wall of the missing soars high over Omaha Beach, etched with names of lost World War II troops and the melancholy mystery of "comrades in arms whose resting place is known only to God."
"Along the wall, set in the American cemetery here on the Normandy cliffs, bronze rosettes mark soldiers whose remains have been found in the 65 years since the D-Day invasion. But for the vast number of missing Americans from the war — almost 73,500 — there are few rosettes and thousands of unanswered questions.
"With time running out to crack the case of the missing soldiers, the United States fields teams of military researchers to search for the remains of World War II troops, but it has limited resources. So much of the detective work has fallen to amateur sleuths in Belgium, France and Germany who hunt for makeshift graves and the ghosts of war. Their tools are Google satellite photos, old-fashioned shoe-leather investigation and high-powered metal scanners that can detect a helmet 20 feet deep."
