Mexico City, September 25 (RHC)-- Mexico's defunct Center for Investigations and National Security (Cisen) recorded 40 videos where various public officials tortured witnesses in the case of the disappearance of the 43 normalistas in 2014, in order to impose the alleged historical truth of the events.

The videos were discovered by the Special Investigation and Litigation Unit according to officials close to the investigation as reviewed by local media.   The 40 recordings make up a dossier built by investigators in the case who have determined that early evidence was tampered with.

The interrogations were conducted during the period from October 2014 to January 2015 and were aimed at having witnesses and suspects in the case repeat the version of events of the then attorney general, Jesus Murillo Karam, and Tomas Zeron de Lucio, who was the director of the criminal investigation agency.

According to the officials, the investigations brought to light that there was a staging of crime scenes, fabrication of evidence, destruction and disabling of evidence, omission of procedures and lines of investigation, insufficient or dismissed investigations, lack of protection of places where there were relevant elements, among other actions.

Local media also revealed that in the recordings appear the former head of the Anti-Kidnapping Investigation Unit of the Attorney General's Office, Guadalberto Ramírez, other officials of the Attorney General's Office and members of the security forces during the administration of then President Enrique Peña Nieto.
  
Likewise, some public defenders were assigned as lawyers for the detainees, applying inhumane treatment to the victims, giving them instructions or witnessing these facts without objection.

The videos are in a file of evidence distributed in 57 digital folders, which are added to other forensic evidence obtained from cell phones illegally extracted by the Attorney General's Office, which will be used in the charges of criminal association against the suspects for falsification of official investigations.
