Guatemala Ex-Dictator Must Appear in Genocide Case A prosecutor says former dictator Efrain Rios Montt must appear in criminal court in a genocide case involving crimes against indigenous Guatemalans during his de-facto government. Federal prosecutor Manuel Vasquez says the retired general must declare on Thursday before a judge, who will decide whether to go forward with genocide charges. Vasquez confirmed Saturday that Rios Montt is a suspect. Rios Montt ruled Guatemala from 1982 to 1983 and has been accused by survivors and family members of mounting some of the worse massacres of the 1963-1996 civil war. He had legislative immunity until his recent term as a congressman expired Jan. 14. Rios Montt has said he operated in a war and is willing to face justice.
