    Barrio Azteca

    For every drug cartel in Mexico, there’s a sister group in America that carry out their dirty work. One of the most brutal of those is Barrio Azteca, based in El Paso, Texas. Originally formed in 1986, Barrio Azteca has become a force of terror in their communities because of their disregard for collateral damage. If you’re on their list, get out of town fast – their traditional method of execution is to beat you half to death and throw you into a pit of burning mesquite, cheering wildly as you agonizingly burn to death. They’ve also been responsible for multiple horrifying massacres, most notably mass murders at several children’s birthday parties.
