On October 18, 1973, Santiago Rubén ROJAS ARANCIBIA, 16 years old, a student, died.

According to the accounts received, the victim left his home in Quinta Buin near the time of the curfew on October 17. From that moment on, his family had no further news of him until they found his body at the Legal Medical Institute, where it had been sent by the El Salto Carabineros station.

Police officers found the body on the El Barrero road at approximately 08:30 hours and stated in the report sent to the Third Criminal Court of Santiago that: "...the deceased presented gunshot wounds to the back, for which it is presumed he was killed by a military patrol for violating the curfew." The death certificate lists the cause of death as: "cranial-encephalic, thoracic, and thoraco-abdominal gunshot wounds with projectile exit."

Based on the evidence gathered and the circumstances and cause of death, the Commission has formed the conviction that the death of Santiago Rubén Rojas Arancibia was the result of the prevailing political violence and is reasonably attributable to the actions of State agents.
