Over one thousand items belonging to the victims were unearthed. In October 2009, the second excavation phase was conducted, which determined the exact placement of double-row barbed-wire fencing posts around the camp. The work revealed numerous new artifacts as well, including false teeth, keepsakes from Marienbad, and many suitcase keys.[20] In the autumn of 2012 the north-western section around mass graves 1 and 2 was analyzed, including geophysical evidence of the barbed-wire enclosure that separated mass graves and cremation pits from the living area of Camp III, and the perimeter of the killing zone as well.[2]
