May 25, 1993 The author standing on the centerline of the collapsed cement roof, with one of two holes, which were smashed through the constructed roof, 0.6 metre (2 feet) distant from the centerline (highlighted in the lower left of photo):

Inspection on the ground showed no solid fence foundations, and no roots of shrubs, at the locations of the thick lines on the 1944 air photos. The wire fences and gates on the map exist just as they did in 1944. On May to September, '44 air photos, marks on the roof of the left alleged gas chamber are all below the center line of the cement roof. Inspection in 1993 of the outside, and inside, of the collapsed cement roof showed that no holes previously existed at these locations below the roof center line. Two holes exist today above the center line of the roof. They were smashed through the cement roof and steel reinforcing rods after September, 1944, because the May to September air photos show no visible holes at these locations. Evidence indicates that persons unknown smashed two holes through the collapsed roof, leaving cut reinforcing rods protruding into the holes, in an atttempt to validate the claim that vent holes were used to introduce Zyklon B cyanide gas pellets. The right alleged gas chamber roof was destroyed in January or February, 1945, and could not be inspected in 1993.
