Nearly 12 years after 43 students from the Ayotzinapa Rural Teachers' College Raúl Isidro Burgos in Iguala, Guerrero, disappeared, documents confirmed that one of the missing students was actually an undercover military informant posing as a classmate.
Alejandro Encinas, Mexico's former undersecretary for human rights and the country's representative to the Organization of American States, shared official documents showing that soldier Julio César López Patolzin had been operating undercover as a student. According to the records, he formally notified his superiors during the early hours of Sept. 26, 2014, that the students had left for Iguala aboard several buses.
