In 1982 amid Guatemala’s brutal civil war, 20 army commandos invaded the jungle hamlet of Dos Erres disguised as rebels. The squad members, called Kaibiles, cut their way through the town, killing more than 250 people. Only a handful survived. One, a 3-year-old boy, was abducted by a Kaibil officer and raised by his family. It took 30 years for Oscar Alfredo Ramírez Castañeda to learn the truth.
