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

-Antonio Ovidio SANDOVAL CARES, 31 years old, who 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 pelted with stones at previous barricades arrived at the location and the protesters allowed it to pass; however, as it was passing, unidentified individuals riding on the bus's step fired at the protesters.

Antonio Ovidio Sandoval was wounded and later died due to a gunshot wound to the face and cranium, according to his death certificate. According to another testimony, the same individuals had fired previously and did so once more 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 is convinced that Antonio Ovidio was a victim of a human rights violation committed by private individuals under a political pretext.
