On October 19, 1973, at 01:20 hours, the following individuals were executed by Ejército personnel near Antofagasta:

Luis Eduardo ALANIZ ALVAREZ […] Dinator Segundo AVILA ROCCO […] Guillermo Nelson CUELLO ALVAREZ […] Segundo Norton FLORES ANTIVILO […] Darío Armando GODOY MANSILLA […] José Boeslindo GARCIA BERRIOS […] Miguel Hernán MANRIQUEZ DIAZ […] Danilo MORENO ACEVEDO […] Washington Radomil MUÑOZ DONOSO, 35 years of age, Comptroller at the Compañía de Cervecerías Unidas (CCU); detained in Antofagasta on an undetermined date and held in the city's prison.

Eugenio RUIZ TAGLE ORREGO […] Héctor Mario SILVA IRIARTE […] Alexis VALENZUELA FLORES […] Marco Felipe DE LA VEGA RIVERA […] Mario del Carmen ARQUEROS SILVA […]

On October 21, 1973, an official statement was published in the Antofagasta press reporting the execution of Mario Silva, Eugenio Ruiz Tagle, Washington Muñoz, and Miguel Manríquez, noting that "the executions were ordered by the Junta Militar of Government…".

On October 24, a second public statement appeared reporting the executions of Luis Alaniz, Danilo Moreno, and Nelson Cuello, indicating that by "resolution of the Honorable Government Junta, on the dawn of the 20th, the firing squad execution of three people took place…", those already indicated.

There was no official version regarding the remaining seven individuals executed on October 19.

Subsequent official statements, from both provincial and national authorities, refer to these executions as if they were the result of carrying out sentences handed down by War Councils. In reports submitted by the government of the time to the Inter-American Commission on Human Rights, it was stated that Eugenio Ruiz Tagle and Héctor Silva, among others, had been prosecuted in case 349 73 before the First Military Court of Antofagasta, with it being proven against Ruiz Tagle "his participation in the crime of embezzlement of public funds… and the transfer of funds to acquire armaments for the Partido Socialista and the Movimiento de Acción Popular. Furthermore, his responsibility was proven in the organization of a terrorist plan prepared for September 18 and 19, 1973… the corresponding tribunal imposed the death penalty, which was carried out by firing squad on October 19, 1973." Regarding Héctor Silva, according to that version, various crimes had been proven against him, including embezzlement of public funds, crimes against State Security, and illegal possession of weapons and explosives, adding that "his participation in these acts was irrefutably proven. In the case, he confessed to his participation as a promoter, organizer, and main leader of a paramilitary organization… In the respective trial… he was sentenced to the death penalty, which was carried out by firing squad on October 19, 1973."

After carefully analyzing the information received and the testimonies collected from various sources, the Commission formed the conviction that the deaths of the fourteen individuals identified above were executions for which State agents, acting outside of all legality, were responsible, which constituted a violation of their human rights, especially the rights to physical integrity, due process, and life.

It bases its conviction on the following considerations:

• Regarding the majority of those executed, there are credible testimonies that while they were deprived of liberty and before being killed, they were atrociously tortured. This, of course, would invalidate any confession provided.
• The official version that reported the existence of a judicial process that would have concluded in the death sentence of the fourteen affected individuals is contradictory to the first information that reported a decision by the Honorable Government Junta;
• That despite the requests made by the Commission, it was not possible to obtain the documents of the trial that supposedly took place against those executed, which, along with the other evidence, leads it to conclude that it never existed;
• That, furthermore, the first version regarding the decision of the Government Junta is consistent with the fact that at the time of the firing squads, a military delegation from Santiago was present in Antofagasta with authority delegated precisely by the highest national authorities;
• That in this last regard, the versions provided by the protagonists are contradictory regarding the origin of the execution orders, but none alleges that a Consejo de Guerra existed;
• That in the event that some kind of trial of those executed had taken place, it occurred without the knowledge of their families and lawyers, which meant that the affected individuals lacked the right to a defense;
• That, whatever the origin of the order to execute the fourteen detainees may have been, military officers and personnel from the Antofagasta Regiment and officers belonging to the delegation from Santiago participated in their firing squad executions.
