Ramiro Osorio Cristales was just five years old when his family was murdered by the Guatemalan army, along with more than 200 other civilians from the Mayan village of Dos Erres. One of the soldiers who participated in the killings, Santos Lopez, took Ramiro with him and later adopted him. In November 2018, Ramiro gave evidence in the trial against his adoptive father for his part in the massacre. He has been telling Mike Lanchin about his horrific ordeal.
