In 1979, Juan Pablo Arévalo dug a well in his land, unaware of the fact that he was digging his own grave. His son, Saúl Arévalo, 54, takes off his black rimmed spectacles, pushes them back to the nape of his neck and points to the place where the Arévalo well was located. Much to the community’s disappointment, water was never found there. Fifteen years after the well was built, in 1994, an Argentinean forensic anthropology team extracted one by one, from that same well, the remains of 162 inhabitants of Dos Erres, including Juan Pablo Arévalo and two of his sons.
