On May 20, 1988, Carlos Arturo GONZALEZ VALENZUELA, 31, a 2nd Sergeant of Carabineros and a musician in the Carabineros National Band, was killed in an attack perpetrated in the Estación Central commune.

2nd Sergeant González was waiting for public transport at a bus stop on Avenida Pedro Aguirre Cerda, at the General Velásquez street underpass, when two individuals approached him. One of them came up from behind and shot him in the head.

The other finished him off, according to eyewitnesses who spoke to the press; they then took his cap and his service weapon, fleeing the scene on foot. As a result of the attack, the victim received six gunshot wounds—two to the head, two to the posterior trunk, and two to the back, as indicated by the autopsy—dying at the scene of the incident.

The evidence examined by the Commission reveals that:

The characteristics of the action are consistent with patterns used by armed groups acting under a political pretext. This is supported by the cold-blooded nature of the operation and the choice of victim.

Another element the Commission took into consideration was that, on the same day, another police officer was killed under very similar conditions, which allows for the presumption of a concerted action intended to cause public commotion while simultaneously seizing weaponry;

The victim had no reasonable possibility of defending himself.

This Commission reached the conviction that 2nd Sergeant Carlos González was a victim of a human rights violation by private individuals acting under political motivations, though it could not specify the group to which they belonged.

That same day, during the night hours, Jaime Orlando SANDOVAL MENDOZA, 27, a 2nd Corporal of Carabineros assigned to the 26th Precinct of Lo Prado, was killed at bus stop 36 on Vicuña Mackenna.

Around 10:00 PM on the aforementioned day, 2nd Corporal Sandoval Mendoza was traveling off-duty, wearing his uniform, in the back of a bus on the Santiago-Puente Alto route.

Two young subjects, who according to the press were carrying backpacks and were also passengers, fired six shots at him when the bus arrived at the Plaza de Armas in Puente Alto. Immediately afterward, they stole his weapon and fled. He died while being transported on the same bus to the Hospital Sótero del Río due to the gunshot wounds received, as established in the autopsy report.

The type of attack suffered by the victim, the cold-bloodedness of the execution—which corresponds to the modus operandi of armed extremist groups acting for political motives—and the consistency with the attack that occurred that same morning, allowed for the presumption of a political motivation for the act; likewise, the victim had no rational possibility of defending himself, as the offenders acted with certainty and surprise.

Therefore, this Commission reached the conviction that 2nd Corporal of Carabineros Jaime Sandoval was a victim of a human rights violation by private individuals acting for political motives.
