Alberto Esteban Palacio González died that day at 14:30 hours, due to asphyxia by hanging, multiple fractures, and homicide, as certified by his Death Certificate. The Autopsy Protocol records that the precise cause of death was asphyxia by hanging and adds that "he was subsequently bound and thrown, possibly from a great height, into the sea, which would explain the external injuries.

This is a homicide" (sic).

According to witness statements, Alberto Palacio, after having been detained by the military in 1973, became an active collaborator for the Dirección de Inteligencia Nacional (DINA) at the clandestine detention site on Londres 38 street and at the prisoner center maintained at the Tejas Verdes Regiment.

He carried out infiltration work involving foreigners exiled from their countries who were in Chile at that time and maintained personal relationships with members of that intelligence group.

On January 10, 1975, he disappeared from his home, located on San Ignacio street in Santiago, and was found four days later floating in the sea at Las Cruces beach, bound with wire. According to the police report documenting the discovery, the body presented lacerations and fractures in both legs.

Classified information received by this Corporation indicates that, before dying, Alberto Palacio was at the Tejas Verdes military facility.

The investigation into the discovery of his body, initiated in the First Criminal Court of San Antonio, was dismissed on the grounds that it was not fully justified that the death was due to the perpetration of a crime.

The Illustrious Court of Appeals of Santiago approved the dismissal but modified the legal grounds, in accordance with the report of its Prosecutor, who concluded that Alberto Palacio was "murdered presumably on the night of January 12 to 13," but that there were no leads to guide the investigation since the perpetrators of the act "acted to ensure their own impunity."

Considering the evidence gathered and the investigation conducted, the Superior Council reached the conviction that Alberto Esteban Palacio González was executed outside of any legal process by State agents. For this reason, it declared him a victim of human rights violations.
