The cellar where Josef Fritzl locked his daughter for 24 years of abuse will soon be no more. Yesterday began a two-week effort to fill it with concrete in order to prevent any future entry, says the liquidator of Fritzl's estate, Walter Anzboeck. Officials had been worried that tourists might want to visit the infamous site, which had already been shut from the inside, the BBC reports; holes will be drilled and concrete will enter the rooms through tubing. The Amstetten, Austria, house itself was also supposed to be destroyed, but now it's set to be sold instead; Anzboeck has apparently managed to find potential buyers. "But the aim was always—and we said this before—to sell the house only if the cellar was not accessible any more," he notes. (More Josef Fritzl stories.)
