Anger over the disappearance of 43 students missing since September reached a boiling point last weekend when one's burned remains were found near a town known for police corruption.

Tens of thousands of people have staged protests in Mexico City over the last few weeks, demanding information as to whether municipal police turned the students over to a drug gang. When fielding questions as to how their bus vanished shortly after being pulled over by police, Mexican attorney general Jesus Murillo Karam simply said "Ya me canse," or "I am tired."

Karam coined the #yamecanse hashtag that, at one point, reached the country's top trending topics on Twitter.

The phrase has been mentioned over four million times in the space of a month, thanks in large part to worldwide support, ranging from the United States to England.

When the hashtag dropped out of Mexico's top ten trending topics, many suspected a conspiracy. A new slogan was born and immediately notched about one million mentions.

The governor of Guerrero, where the abductions took place, has resigned and dozens suspected of involvement have been arrested, including the mayor of Iguala and his wife. President Pena Nieto recently unveiled a set of proposals that would turn over public safety to larger state police departments, though many analysts are quick to point out that Nieto doesn't go far enough to confront the lawlessness in many parts of the country.
