The UN and other international bodies have refuted the “historical truth” presented by the Peña Nieto administration
This enforced disappearance case revealed the corruption, human rights violations, and impunity that plague Mexico
Tomás Zerón was at the center of the investigation that has failed to determine the whereabouts of the 43 students of Ayotzinapa, who were allegedly handed over to a drug gang and slain.
Julio César Mondragón suffered 64 fractures in 40 bones, mostly in his skull, face and spine.
Human rights groups that represent the parents issued a statement in which they asked that Tomás Zerón "be fired from his post so that he can be investigated for crimes related to obstruction of justice."
The experts criticized prosecutors' decision to release a report last week saying there was a fire at the dump and the remains of at least 17 people were found there.
Sources said the mayor was detained along with Adán Zenen Casarrubias, allegedly leader of Guerreros Unidos cartel.
They faced Ayotzinapa students.
The main points of the report about the disappearance of the Ayotzinapa students released by an independent group of experts from the Inter-American Court on Human Rights.
The group said that the giant funeral pyre in which the attorney general said the Ayotzinapa students were burned to ash beyond identification simply never happened.
