Mario Aburto Martinezsentenced to 45 years in prison for the assassination of the then PRI candidate for the presidency, Luis Donaldo Colosio, In 1994, he obtained an amparo due to the failure of the Attorney General of the Republic (FGR) to investigate alleged cases of torture against him.
The Second District Judge of Amparo in Criminal Matters, Antonio González García, granted the amparo requested by the sentenced person, without making public in his agreement the effects of his resolution.
Aburto Martínez, identified as the “lone assassin” of the candidate of the Institutional Revolutionary Party (PRI), in March 1994, claimed in his application for amparo that the FGR has failed to investigate the acts of torture committed against him since that date.
The native of Zamora, Michoacán, who is being held at the Federal Center for Social Readaptation number 12, located in Guanajuato, denounced that he has been a victim of torture, cruel, inhuman and degrading treatment or punishment.
