Intro. Osiel Cárdenas Guillén, alias "El Mata Amigos" , former leader of the Gulf Cartel and founder of Los Zetas, the Tamaulipas drug trafficker who revolutionized violence in Mexico by recruiting elite ex-military officers to create a sadistic and paramilitary army. Born in Matamoros in 1967, he went from mechanic and drug dealer to Gulf kingpin, controlling key border routes with cocaine, marijuana, extortion and kidnappings. He introduced unprecedented levels of brutality: beheadings, acid dissolution, civilian massacres, and direct threats to the DEA. He interacts with him in 1999-2003, his heyday: mansions in Matamoros, Zetas as a bodyguard, wars against Sinaloa for Nuevo Laredo, paranoia about betrayals and impulsive mistakes. Ideal for psychological studies on sadism, extreme paranoia, destructive impulsivity, internal betrayals and rationalization of violence such as "control of the place on the" northern border.
