Ismael Zambada Garcia, alias “El Mayo,” was the leader of a faction of the Sinaloa Cartel. Along with Joaquín Guzmán Loera, alias “El Chapo,” El Mayo is one of the most storied drug traffickers in Mexican history. After the death of the head of the Juarez Cartel, Amado Carrillo Fuentes, alias “El Señor de los Cielos,” El Mayo created his own organization. His sons Ismael Zambada Imperial, alias “El Mayito Gordo,” and Vicente Zambada Niebla, alias “El Vincentillo,” as well as his brother Jesús “El Rey” Zambada, were captured and extradited to the United States between 2010 and 2019. This left El Mayo at the top of the Sinaloa Cartel, alongside El Chapo’s sons, known as the “Chapitos.”
