On January 13, 1975, Ramón Hugo MARTÍNEZ GONZALEZ, a student and member of the Central Committee of the MIR, was killed by DINA agents. He had been detained on the 6th on Calle Bascuñán Guerrero in Santiago. At the time of his arrest, Ramón Martínez was wounded by gunfire and was taken in that condition to the Villa Grimaldi facility.

On the 13th, his body was sent to the Legal Medical Institute by a Military Prosecutor's Office, where it was recorded that he died as a result of two recent thoracic gunshot wounds, which did not correspond to those inflicted at the time of his arrest. This evidence allows for the conclusion that the victim was executed by DINA agents, in violation of his human rights.
