En route to a demonstration that sought to protest policies that gave urban student-teachers an advantage over rural student-teachers on the job market, 43 students from the Escuela Normal Rural Raúl Isidro Burgos Rural de Ayotzinapa, a teacher training college in Guerrero, Mexico, were ambushed by police and disappeared. Additionally, 6 unarmed people were killed and 25 injured by police. Six months later, the students who survived the ambush and the families of the disappeared students are still waiting for answers. Investigators claim that the students were all killed after being turned over to a drug cartel, yet among the dozens of bodies discovered in the surrounding area, only one student has been confirmed dead through a DNA match, which attests to the widespread disappearances that plague Mexico today, estimated at over 22,000 since 2006.
