September 26 marks the second anniversary of the night student teachers were attacked by police in the city of Iguala, Guerrero. Three students and three bystanders were killed in the attacks and 43 students were disappeared. The case sparked months of angry demonstrations in Mexico that seriously damaged President Enrique Peña Nieto’s image both at home and abroad.

“This is one of the worst cases of human rights violations seen in Mexico’s recent history. Two years later, the Mexican government has done very little to help these wounds heal. It is shocking that, despite dedicating significant resources, the Mexican government has not found the students, and that its own officials have obstructed the investigation,” said Maureen Meyer, Senior Associate for Mexico at WOLA.

Two years after 43 students were disappeared by police officers in collusion with a criminal group in Mexico, there have been no convictions, progress in the investigation has stalled, and compelling evidence points to an obstruction of justice in the case.

An international panel of legal and human rights experts who spent a year studying the case questioned the Mexican government’s ability and willingness to get to the bottom of it.

Since the experts’ departure in April, the government has broadened its investigation to include a wider range of possible suspects. In addition, the attorney general’s top investigator resigned amid an internal affairs inquiry into his handling of the case.

Still, there is a prevailing feeling here and abroad that the Mexican government alone cannot be left to figure out who was behind the violence in Iguala in Guerrero State on the night of Sept. 26, 2014, and what happened to the students, most of them freshmen. Many observers are now pinning their hopes for justice on the Washington-based Inter-American Commission on Human Rights, which will deploy a team to shadow the investigation.

Today numerous protests throughout the country are announced.
