After a student protest in Iguala, Mexico, last month, dozens of young men were seen being hauled off into police vans. Then, they vanished.
One month later, 43 students from the Ayotzinapa rural teachers college are still missing and presumed dead. Instead of finding the students, authorities investigating the events of Sept. 26 have instead found other horrors: a string of mass graves, police working for drug cartels and government officials at the helm of a dark underworld.
The hunt for the students has laid bare the brutality and lawlessness in parts of Mexico still under the grip of the cartels, despite years of Mexico’s war on drugs.
