On 26 September 2014, 43 students from the Raúl Isidro Burgos Rural Teachers' College in Ayotzinapa were kidnapped, disappeared, and likely murdered, provoking ongoing national protests and international attention. Mexican Federal Police and Iguala's police department and former mayor have been implicated in the students' kidnapping and disappearance; members of the "Guerreros Unidos" drug cartel in the mass murder. The governor of Guerrero state, Ángel Aguirre Rivero, resigned amid the scandal.
