Rafael Caro Quintero, nicknamed “El Narco de Narcos” (The Narco of Narcos) is the founder of the now defunct Guadalajara Cartel—one of the most powerful drug cartels of the 1980s that later splintered into various groups, including the Sinaloa Cartel, one of the world’s most powerful criminal organizations and drug cartels.

Drug lord Rafael Caro Quintero, the alleged killer of Drug Enforcement Administration (DEA) agent Enrique Camarena in 1985, has been extradited to the US from Mexico, nearly four decades after the incident.
