Salustio Herrera Riveros died that day at 13:30 hours on a public thoroughfare, due to gunshot wounds to the head and thorax, as stated in the Medical Death Certificate from the Legal Medical Institute.

In 1991, during the investigation by the 22nd Criminal Court of Santiago regarding illegal burials in Patio No. 29 of the General Cemetery of Santiago, it was determined that the body of Salustio Herrera had been sent by officers from the Vista Alegre Station of the Carabineros to the Legal Medical Institute as a "male NN," where, despite subsequently being identified through his fingerprints, he was buried as a "male NN" in the aforementioned cemetery.

Considering the evidence gathered and the investigation conducted by this Corporation, and notwithstanding that the precise circumstances of his death remain unknown, the Superior Council, taking into account the era, the cause of death, and the place of burial, declared Salustio Herrera Riveros a victim of the prevailing political violence.*

*Subsequent to the classification of this case, on May 3, 1995, in the aforementioned investigation, after it was corroborated that Autopsy Protocol No. 2989/73 corresponded to Salustio Herrera Riveros, the delivery of his remains to his family members was ordered.
