In 2008, it was revealed that Colombia’s army had been executing civilians and pretending they were rebels killed in the country’s ongoing civil war. At least 4,600 innocent people were murdered in this way. They became known as the ‘false positives’.

Ben Henderson speaks to Jacqueline Castillo, whose brother was one of the victims, and Carlos Mora, who was ordered to execute civilians when he was a soldier.
