Friday, Mexican officials announced that the navy had detained Rafael Caro Quintero, a founding member of one of Mexico's most significant drug cartels.
Caro Quintero and Miguel Angel Felix Gallardo co-founded the Guadalajara Cartel, an organization that generated three of the largest drug organizations in Mexico.
Allegedly, the Guadalajara cartel was the biggest supplier of marijuana, cocaine, and heroin to the United States, making it the primary target of American law enforcement.
Caro Quintero spent 28 years in prison after being arrested in 1985 for multiple crimes, including the kidnapping, torture, and murder of US Drug Enforcement Agency (DEA) agent Enrique 'Kiki' Camarena.
Camarena's successful infiltration of the Guadalajara Cartel resulted in one of the cartel's most devastating blows.
In 1984, in a combined operation with the DEA, Mexican officials recovered 4,000 tons of marijuana from Caro Quintero's property, the largest drug seizure in Mexican history.
Caro Quintero, who blamed Camarena for the multimillion-dollar loss, allegedly ordered his kidnapping and death.
After a federal judge ordered his release in 2013, the Mexican Attorney General's Office issued a second arrest warrant for Caro Quintero, this time for extradition to the United States.
Caro Quintero has been on the run since his arrest warrant was issued. The DEA offered up to $20 million for information leading to his capture and becoming the agency's most sought-after fugitive.
He has denied involvement in narcotics trafficking.
