The office of Mexico's attorney general posted on its website Sunday the 54,000 pages of documents from the much-criticized investigation into a case that has bedeviled President Enrique Pena Nieto's administration.
A review by AFP of hundreds of pages found contradictory testimony among some of the more than 100 suspects who have been detained, including Guerreros Unidos drug cartel members and municipal police officers.
The report -- a maze of documents divided into 85 tomes and 13 annexes with several typos and redacted information -- was made public by Attorney General Arely Gomez following freedom of information requests from journalists. It is rare for Mexican authorities to make investigative documents public online.
Murillo Karam said the officers abducted 43 students and handed them over to the Guerreros Unidos drug gang, which confused them with rivals, killed them and incinerated their bodies at a garbage dump in the neighboring town of Cocula.
