I've heard of them for a few years as far as my state goes. Hearsay around these parts coincide with what you were commenting: That they are a drug cartel that didn't like it when the Zetas came around enforcing an almost feudal age business of extorsion.
I hate the fact that there's so much censorship and media control here(Mexico) to really get an educated opinion through local media, they seem to use fear to keep us ignorant and docile!
