From 1962 until 1973 Alma Guillermoprieto was a professional dancer. Subsequently however the details of the massacre as first reported by Guillermoprieto and Bonner were verified with widespread repercussions. In January 1982 Guillermoprieto then based in Mexico City was one of two journalists (the other was Raymond Bonner of The New York Times) who broke the story of the El Mozote massacre in which some 900 villagers at El Mozote El Salvador were slaughtered by the Salvadoran army in December 1981.
