Authorities in Mexico have ordered the arrest of the Mayor of the southern town of Iguala, where 43 students were last seen in late September being bundled into police vans after a raucous protest against corruption.  The Mayor allegedly ordered cops to intercept the students before they disrupted an event hosted by his wife.

“We have issued warrants for the arrest of Iguala Mayor Jose Luis Abarca, his wife Mrs. Pineda Villa, and police chief Felipe Flores Velazquez, as probable masterminds of the events that occurred in Iguala on 26 September," Attorney General Jesus Murillo said at a press conference in Mexico City.

The mayor and his wife are reportedly on the run.  She allegedly had ties to the local drug gang Guerreros Unidos.  The leader of the gang and several cops are among the 52 people arrested so far in this investigation.

Public disgust over the disappearances is not going away.  DNA tests showed that the students were not among the dozens of bodies found in a series of mass graves discovered outside Iguala in the investigation.  In a country where 100,000 people have been killed in drug gang violence since 2007, it suggests undiscovered atrocities beyond the case of the missing students.

Thousands marched in Iguala on Wednesday to protest the disappearance of the teachers in training.  After the march, masked men set fire to the municipal offices with Molotov cocktails and smashed the windows.
