On December 1, 1975, the deaths of José Hernán CARRASCO VASQUEZ and Humberto Juan Carlos MENANTEAU ACEITUNO occurred. Both were leaders of the MIR and were detained by the DINA in late 1974.

While in that situation, they participated alongside two other leaders in a televised public statement and a press conference where they called on their fellow members to end the armed struggle. They subsequently remained detained for several months at Villa Grimaldi, separated from the other prisoners, until they regained their freedom in September 1975.

While in that situation, they were detained by armed civilians: Humberto Menanteau on November 19, while he was at his parents' house, and José Carrasco the following day at the home of some friends. Their bodies were identified by their relatives on December 10 at the Legal Medical Institute, having been found in the vicinity of Buin. They showed signs of having been tortured before being killed.

Previously, and while they were still detained, the press published information that the MIR had sentenced the participants of the statement and the press conference to death. Once they were dead, the relatives received letters informing them that they had been executed by the MIR, accused of having betrayed the working class.

This Commission reached the conviction that this version is not factual, by virtue of statements in its possession indicating that the kidnappers were DINA agents who had periodically visited them since they had been released, and who killed them upon receiving news that they were attempting to restore their relations with the MIR.

The foregoing is ratified by the fact that they were seen at the DINA barracks Villa Grimaldi during this second detention. For this reason, the conviction has been reached that the aforementioned victims were executed by DINA agents, in violation of their human rights.
