On August 30 and 31, 1988, street demonstrations were held in opposition to the nomination of President Augusto Pinochet as a candidate for that year's plebiscite. Four people were killed during these events:

-Edison Freddy PALMA CORONADO, 15 years old, was a student. On the night of August 30, a group of people marched along Avenida Grecia to Calle Ictinos (Santiago), near an open community center. At that location, he died due to "thoracic-cardiac-pulmonary trauma caused by a bullet," though it has not been possible to determine the circumstances or the origin of the shot.

The information gathered by this Commission leads it to the conviction that Edison Palma fell victim to political violence.

-Sergio Williams ALBORNOZ MATUS, 14 years old, worked as a bricklayer's apprentice.

On August 30, warehouses located in a municipal park near Villa La Cultura (Santiago) were raided and set on fire by demonstrators. Carabineros and firefighters arrived at the scene. In that context, shots were fired from firearms of various origins. A bullet struck him, causing his death.

The specific details of the event and the general data regarding the context allow this Commission to reach the conviction that Sergio Albornoz died as a victim of the political violence of the period.

-Carlos Eugenio ARANCIBIA CANTILLANA, 23 years old, was killed by a gunshot while on the street on the night of August 30, following street demonstrations in the city of Quillota.

The gathered information indicates that he had been participating in a march and later in barricades-bonfires. There, he stated that he was being followed by a car. A witness heard someone being chased—presumably the victim—and then heard shots fired at him. Carlos Arancibia managed to reach a location a few blocks away from his parents' house.

The evidence presented allows this Commission to form the conviction that Carlos Arancibia was a victim of the actions of private individuals, who violated his human rights for political motives.

-Antonio Ovidio SANDOVAL CARES, 31 years old, worked as a carpenter.

On the night of August 30, a barricade was set up near the intersection of Avenida Santa Rosa and Calle Venancia Leiva (Santiago). According to testimonies known to the Commission, a public bus that had been stoned at previous barricades arrived at the location, and the demonstrators let it pass; however, as it was passing, unidentified individuals on the bus's step fired at the demonstrators.

Antonio Ovidio Sandoval was wounded and subsequently died due to a gunshot wound to the face and cranium, according to his death certificate. According to another testimony, the same subjects had fired previously and did so again afterward, in different locations, before getting off.

The evidence presented allows for the presumption of a political motive on the part of the perpetrators. This Commission holds the conviction that Antonio Ovidio was a victim of a human rights violation committed by private individuals under a political pretext.
