Declassified documents show that U.S. officials knew the Guatemalan Army was responsible for the 1982 mass murder http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB316/index.htm

The complaint alleges that Jordan, a naturalized American citizen, was part of the special counterinsurgency Kaibiles unit that carried out the massacre of hundreds of residents of the Dos Erres village located in the northwest Petén region. Jordan allegedly helped kill unarmed villagers with his own hands, including a baby he allegedly threw into the village well.
