On the night of September 26, 2014, local police in the southern Mexican city of Iguala, Guerrero, killed six people and disappeared forty-three students from the Ayotzinapa rural teachers college. It quickly became clear that the police had handed the students over to a local drug cartel, Guerreros Unidos, whose leaders are relatives of the wife of Iguala Mayor José Luis Abarca.

But even with the recent passing of the six-month anniversary, there are still discrepancies between official and reported accounts. According to the federal government, the students were killed, then chopped into pieces and burned, their ashes spread at a dump; the attorney general later called this version the “historical truth.”

However, Proceso magazine found that both the army and the federal police were involved, with the latter directly tied to the shootings. Later that night, the magazine reports, the army kicked a group of wounded students out of a private health clinic. “You’re looking for your own deaths,” an officer told them after he made them get on the floor. (Eventually, people from the neighborhood helped them get to another hospital.)
