ProPublica’s Sebastian Rotella tells the story of Oscar Alfred Ramírez Castañeda, whose family lived in a remote village that was attacked as part of a government offensive in 1982, when he was still a child. Castañeda never knew that he had lost almost his entire family, but he was reunited with his father earlier this week, thanks to technologies and resources that are only now helping prosecutors and victims piece together what happened during the three-decade civil war in Guatemala in the hopes that justice will be served.
