Nazi photo is key to mass grave found in Moscow

Russian historians have used a Nazi bomber pilot’s photograph to help them find a mass grave in Kommunarka in south-western Moscow containing the remains of thousands executed by Stalin’s secret police in the Thirties.

The Gulag History Museum said an aerial shot of the district taken by a Nazi pilot in 1942 was key, as it showed the height of the trees in the area at the time and concluded that trees had been planted over fresh graves.
