Their remains were discovered in a mass grave on the road to San Pedro de Atacama, only 15km away from Calama. The Rettig Commission report established that the victims were brutally mutilated and massacred. The secret burial in a mass grave was carried out to avoid confrontation with the victims' relatives, who later defied the atrocities of the dictatorship and embarked upon a personal search of the Caravan of Death victims.
