Video here from a while back shows a man who has been captured by one of the Mexican Cartels. He is condemned and then gagged. A knife is then pressed to his throat and his head is violently sawn through with the remaining flesh being hacked off. Pretty wicked looking blade they were using. That’s about all there is to report. I don’t know who claims responsibility for it or who the victim was or what he had done.
