Juan Jose Esparragoza Moreno
After the implementation of Operation Condor (Spanish: Operación Cóndor), a Mexican antidrug program carried out in the 1970s to stop the flow of drugs from Mexico to the United States, many drug traffickers from the state of Sinaloa regrouped in Guadalajara, Jalisco to continue their operations. The regrouping led to the formation of the Guadalajara Cartel, a drug trafficking organization that eventually managed to control nearly all the narcotics trafficking operations in Mexico throughout the late 1970s and 1980s. Among their original founders were Miguel Ángel Félix Gallardo (alias "El Padrino"), Ernesto Fonseca Carrillo (alias "Don Neto"), Rafael Caro Quintero, Esparragoza Moreno, and other Sinaloan drug kingpins. Throughout most of the 1970s and early 1980s, most of the cocaine that was smuggled to the United States was trafficked by the Colombian drug cartels through Florida and the Caribbean Sea. However, with increased law enforcement measures in these areas by the mid-1980s, the Colombian drug kingpins shifted their operations to Mexico.
