On October 10, 1973, Juan Bautista VERA CARCAMO, 23 years old, an official of the Agrarian Reform Corporation (CORA) and a sympathizer of the Partido Socialista, was killed in Valle Simpson by military personnel.

After September 11, the victim had gone to work on a property he owned located in the Valle Simpson sector. On October 10, a patrol consisting of military personnel and civilians arrived at that location and killed him.

The family learned of Juan Bautista Vera's death via the radio and found his body at the Coyhaique morgue. The body showed signs of several bullet impacts, and the respective death certificate indicates the cause of death as, "ordered by the military authority, gunshot wound." An Ejército officer is listed as the requester of the registration, and a professional from the same institution is listed as the certifying physician.

The official version, which appeared in the newspaper El Llanquihue on October 20, states that "the detainee Vera, on the way from his room to the vehicle that was to transport him to Coyhaique, grabbed an axe attempting to attack the members of the patrol, who proceeded to use their weapons, resulting in his instantaneous death."

It is the conviction of the Commission that a grave violation of his fundamental rights was committed in the death of Juan Vera, constituting an execution outside of any legal process, given that it is implausible that the victim, already arrested by his captors, could have grabbed an axe to attack them, especially since the habitual practice of police and military officials during arrests was always to ensure, even with violence, the effectiveness of the apprehension; and that even in the unlikely event that the alleged aggression had occurred, these officials are generally in a position to prevent acts of such nature with appropriate means, without the need to resort to killing their detainees.
