On December 17, 1981, Iván Alfredo QUINTEROS MARTINEZ, 31 years old, a MIR militant and merchant, was killed. According to the press, he died in a confrontation with security forces in front of No. 437 of Callejón Lo Ovalle, two blocks from the 17th stop of the Gran Avenida.

Witness statements indicate that the victim was riding a bicycle along Callejón Lo Ovalle when he was struck by a Suzuki-type van driven by CNI agents, who ordered him to stand up. Iván Quinteros was unable to do so and fell to the ground again, at which point they shot him, leaving him gravely wounded; he died shortly thereafter.

The autopsy report records that the victim received five bullet wounds.

The Commission, considering the gathered evidence, the victim's political affiliation, the inaccuracy of the official statement, and the surveillance he was under due to his connection with María Cienfuegos and Sergio Flores, who had been killed days earlier, has reached the conviction that Iván Quinteros was executed by CNI agents, considering his death a human rights violation for which state agents are responsible.
