Mexico City, August 20 (teleSUR-RHC)-- The Mexican attorney general has been ordered to hand over all information pertaining to the infamous 1968 student massacre in Tlatelolco, Mexico City, as well as the Corpus Christi Massacre of 1971 – information that may implicate former President Luis Echeverria Alvarez in the crimes.

National data and transparency institute INAI gave the order Wednesday. With this decision, the INAI has effectively removed a 12-year block on all such information, which was imposed by former President Vicente Fox during his presidency. Fox implemented the information block in 2007, after he dissolved the government body responsible for looking into historic atrocities against political and social movements, including the two student massacres.

Echeverria has long been suspected of ordering the '71 attack on the student protesters, what killed almost 120 people.  He was also condemned for not bringing the perpetrators to justice.  Hundreds were disappeared during the “Dirty War” period between 1968 and and the late ‘70s, which was characterized by police and military repression.

The former president is also believed to be involved in the '68 Tlatelolco massacre, when he was serving as interior minister.  He was even charged with genocide, but a judge dismissed the case in 2005, ruling that the attack did not constitute genocide.

INAI President Ximena Puente said the organization is forcing the attorney general's office to release the secret documents now because the people deserve to know the truth and in order to make sure that such events could not repeat themselves.
