The investigation to clarify the disappearance of the 43 students of Ayotzinapa is not closed, emphasized President Claudia Sheinbaum Pardo, noting that the presentation of new progress on the case does not represent the culmination of the investigations.

During her morning press conference, the president explained that the report will be presented before the Attorney General’s Office and the Interior Ministry, and specified that the information to be released has already been shared with the parents of the students of the Raúl Isidro Burgos Rural Normal School.

She detailed that the progress includes new lines of investigation developed through mechanisms and methodologies that, according to what the president set out, had not been used previously in the investigation files. Results obtained from the analysis of the phones used during the events will also be presented.

For that reason, she insisted that the presentation does not represent the closing of the investigations, but rather the exposition of the “new elements and where they are leading.”

The president also highlighted that communication is maintained with the parents of the 43 students through the Undersecretariat of Human Rights of the Interior Ministry, the Commission for the case and the Attorney General’s Office.

“We have a relationship with them, both through the Interior Undersecretariat of Human Rights, the Special Commission, and the Attorney General’s Office,” she said. She added that some particular requests from the families are attended to directly.

She clarified that the information to be released this September 28 corresponds to what was presented to the parents during the last meeting she held with them at the National Palace.

On the parents’ demand for the return of the members of the Interdisciplinary Group of Independent Experts (GIEI), Sheinbaum Pardo noted that this group no longer exists because it was dissolved by the Inter-American Commission on Human Rights.

She recalled that when the government asked the United Nations for an assessment of experts who could support the investigations, it was decided not to call on the GIEI members again, but rather to consider other specialists, whose incorporation is still in the process of being defined.

Finally, the president announced that she will request the presence of the Undersecretary of Human Rights, Population and Migration of the Interior Ministry, Arturo Medina, at the September 29 press conference, with the purpose of expanding the information related to the new lines of investigation in the Ayotzinapa case.
