The Underworld Podcast
Underworld exposes the secret world of transnational criminal networks that have flourished since there were banks to bust, drugs to smuggle, and scams to run. Journalists Danny Gold and Sean Williams bring their experience reporting on dangerous people and organizations to take listeners on a global tour of mobsters, warlords and crooks - from Brooklyn to Beijing, from the streets to the boardrooms - and everywhere in between. Underworld is a show about heroes, villains, and the barely visible mafias that affect all our lives, whether we know it or not.

The OG Mexican Narco: Pablo Acosta
Pablo Acosta ruled Mexico's drug trade from a dusty border town, turning Ojinaga into a narco-empire that funneled billions in cocaine, weed and heroin into America during the 1980s. Known as the Fox of Ojinaga, he was a ruthless trafficker who taught the narco-world that it was better to buy the authorities than fight them.
His dealings with the Colombian cartels changed the Mexican underworld as we know it...until a coke problem and a bloody FBI-backed raid in 1987 turned a remote Mexican village into a war zone. This is the story of the man who pioneered the border drug corridor, leaving a legacy that still shapes the cartel wars today.
