Mejia is charged with ordering the massacres of Mayan leftist guerilla fighters, during 1982 to 1983, when he served as chief of the military. Mejia's military reign are widely asserted to have corresponded to the war's bloodiest years.
He later led a military coup agaist then dictator Efrain Rios Montt and appointed himself president from 1983 to 1986.
