“The Cantuta in the devil’s mouth”, the documentary directed by Tilsa Amanda Gonzales and produced by TV Cultura, addresses one of the atrocities committed by state apparatus, through the Colina Group, during the dictatorship of Alberto Fujimori. The project focuses on the testimony of Edmundo Cruz, a key event in the story of La Cantuta, as part of the team of the magazine “Sí” he researched and published on the killings between 1991 and 1993. The researches provided strong evidence that subsequently have been critical for 25-year sentence to ex-President Fujimori for violation of Human Rights. We will release the old man remembering the experience from the research, the approach to the sources, the exploration of the scene, and reflect on the dangerous profession and vocation of confronting the powerful people.
