Yineth Trujillo was recruited by the Farc - Colombia's largest guerrilla group - when she was 12 years old.
She fought for them for three years. She told reporter Tom Esslemont how new recruits were forced to watch executions, and how combatants were forced to dig their own graves before being executed.
She now lives with her two daughters just outside the capital city Bogota.
