La Cantuta

The pattern, confirmed within nine months — same unit, same logic, nine more bodies in a kiln.

On 18 July 1992, Grupo Colina enters the Universidad Nacional de Educación Enrique Guzmán y Valle, known as La Cantuta, and abducts a professor and nine students. They are killed and buried; later, their remains are exhumed, cremated in a brick kiln, and reburied. The detail of the kiln matters because it tells you what the unit understood about its own work — that the bodies, if found, would be evidence not of an excess but of the system. The class gradient is already visible: rural-origin students at a teachers' college, a professor from a working-class background. The apparatus learns very fast where the cost of a mistake is lowest, and concentrates there. It will learn this lesson again in every country that runs the experiment.
