The 43 students have received far more attention than other disappeared, in part because allegedly corrupt police in Iguala, in southern Mexico, so clearly played a role in their Sept. 26 disappearance.

MEXICO CITY (AP) - An off-the-cuff comment by the attorney general to cut off a news conference about the apparent killing of 43 missing college students has been taken up by protesters as a rallying cry against Mexico's corruption and drug trade-fueled violence. During the session that was televised live Friday, Attorney General Jesus Murillo Karam announced that two suspects had led authorities to trash bags believed to contain the incinerated remains of the slain students, who haven't been seen since being led away by police in the southwestern town of Iguala on Sept. After an hour of speaking, Murillo Karam abruptly signaled for an end to questions by turning away from reporters and saying, "Ya me canse" - a phrase meaning "Enough, I'm tired." Within hours, the phrase became a hashtag linking messages on Twitter and other social networks. It continued to trend globally Saturday and began to emerge in graffiti, in political cartoons and in video messages posted to YouTube. Many turned the phrase on the attorney general: "Enough, I'm tired of Murillo Karam," says one. Another asks: "If you're tired, why don't you resign?" Other people used it to vent their frustrations with messages such as "Enough, I'm tired of living in a narco state" or "Enough, I'm tired of corrupt politicians." Mexicans have reacted with outrage to the disappearance of the students from a rural teachers college and a government response that has failed to fully explain what happened. Investigators say Iguala Mayor Jose Luis Abarca and his wife, Maria de los Angeles Pineda Villa, ordered police to confront the students, who had gone to Iguala to raise money and had commandeered passenger buses for their use. The couple reportedly feared the students would disrupt an event being led by the wife. Iguala police fired on the students in two incidents, killing six people. Officers then allegedly turned over 43 arrested students to a local drug gang. Murillo Karam said members of the gang confessed to killing the students before burning their bodies and tossing the ashes and bone fragments into a river. At least 74 people have been arrested, including Abarca and his wife, who were found Tuesday hiding in a dilapidated home in a rough section of Mexico City. Families of the missing students insisted they will continue to believe their sons are alive until authorities prove the recovered remains are theirs. Murillo Karam said the bone fragments would be sent to a lab in Austria for testing. Manuel Martinez, a spokesman for the families, said the "YaMeCanse" rallying cry was proof that their demand for answers is gaining strength. "The people are angered and I hope that they continue support us," he said Saturday. Filmmaker Natalia Beristain was among hundreds of people posting YouTube videos tagged #YaMeCanse. "Senor Murillo Karam, I, too, am tired," she said. I'm tired of vanished Mexicans, of the killing of women, of the dead, of the decapitated, of the bodies hanging from bridges, of broken families, of mothers without children, of children without fathers. "I am tired of the political class that has kidnapped my country, and of the class that corrupts, that lies, that kills," she added. I, too, am tired.
