On October 2, 1973, the following individuals were killed by members of the Army:

Hugolino Humberto ARIAS NAVARRETE, 35 years old, a rural technical teacher in the Linderos area,

Víctor Omar GALVEZ NORAMBUENA, 21 years old, a rural technical teacher in the Linderos area, and

Nelson Joaquín MEDINA LETELIER, 23 years old, a rural technical training teacher in the Linderos area.

By order of the new authorities on September 11, 1973, classes were suspended until the country's circumstances normalized. Subsequently, teachers were ordered to report to their workplaces on October 1.

Thus, these three teachers went to teach their classes at the Escuela Técnico Rural de Linderos, where they were employed. They were awaited there by Carabineros from the Buin police station, who arrested them.

There was a fourth teacher whom they were waiting for, but who was warned at the train station not to show up because his coworkers had been arrested. That same afternoon, they were taken to the Buin Carabineros station, where they were registered as "extremists," according to the station's detention logbook.

However, in the afternoon, they were removed from the site by an officer from the Escuela de Infantería de San Bernardo and transferred to the Cerro Chena detention camp. The following day, they were executed at that detention center; as certified by autopsy protocols, their bodies showed multiple gunshot wounds to the chest and head.

The families were permanently denied that the arrests had taken place, and the deaths were not communicated to them either. However, through other means, they were later able to learn of the outcome and that the bodies of their relatives were buried in Patio 29 of the General Cemetery. The families of Hugolino Arias and Víctor Gálvez managed to exhume their bodies and confirm their identities.

The Commission reached the conviction that the victims were executed outside of any legal process by state officials, in violation of their fundamental rights, finding sufficient evidence in the record of the arrests and the manner in which the deaths occurred.
