Although no conclusive proof connects the Weisfeiler's disappearance to any entity, some American and Chilean officials do suspect one particular group. Unknown to most of the world, Colonia Dignidad sat on a large tract of land not far from the border with Argentina. Idyllic in appearance, the Colonia was run by German who included alleged Nazi war criminals and sympathizers. The leader of the Colonia for most of its existence was former Nazi Paul Schäfer. The Colonia had a cult-like atmosphere, in which many children were molested, a crime for which its leaders have faced prosecution; Schäfer himself was convicted in May 2006, in connection with allegations of child abuse at the Colonia. The BBC has reported and Chilean governmental documents suggest that the Chilean "Dirección de Inteligencia Nacional" (the secret police, which was disbanded in 1977) brought suspected anti-government prisoners there to be interrogated.
