A year ago, what seemed to be a normal protest from the students from the ‘Escuela Normal Rural’ of Ayotzinapa Isidro Burgos, in the state of Guerrero in Mexico, quickly turned into a tragedy. At the time, the students allegedly arrived in a few buses to the town of Iguala where they were going to raise funds. Reportedly, when the local police accused the students of having stolen the vehicle they were on, violence escalated quickly and policemen started shooting students while they ran for their lives. As investigations reportedly developed, this version has been practically dismissed and the government’s involvement has become the top suspicion.

Relatives of the 43 students, who were apparently kidnapped and massacred a year ago, are still demanding answers, accusing President Enrique Peña Nieto of ignoring their demands to solve a crime that has battered their lives. The families asked the government to launch a new internationally supervised investigation and to review Mexico's own investigators, after international experts cast doubt on Mexico's official account of the incident.
