The Gulf Cartel: Osiel and the Birth of the Zetas

This is the story of the Gulf Cartel under the man they came to call El Mata Amigos — the Friend Killer. The story of how he rose to control one of the oldest and most powerful trafficking organizations in Mexico. And, above all, the story of the army he created to protect himself — an army of trained soldiers that would grow beyond his control, break away from him entirely, and become one of the most feared criminal organizations the country had ever seen. Los Zetas.
