It found that crime was committed against 350 victims.
Six workers from the Mercedes Benz plant were among them. They were taken by right-wing death squads because they had union sympathies.
The men were tortured at the Campo de Mayo detention center run by Gen Riveros just outside Buenos Aires.

Over a period of three years, the investigating judges interviewed approximately 750 witnesses.
