Joaquín "El Chapo" Guzmán, infamous kingpin of Mexico's Sinaloa Cartel, was unanimously found guilty on all 10 counts against him by a federal jury in Brooklyn, New York, on Feb. 12. He was convicted of overseeing an international criminal conspiracy to import tons of cocaine, heroin, methamphetamine and marijuana into the United States over a 20-year period, and laundering the billions of dollars in proceeds.

Mexico's most notorious kingpin, Rafael Caro Quintero, was released Aug. 9 from Puente Grande federal prison in Jalisco where he had been incarcerated for the past 28 years. He left the facility at dawn, several hours before the release order was made public. The First Appellate Tribunal in Guadalajara found in March that Caro Quintero was improperly tried for the 1985 torture-killing of DEA agent Enrique "Kiki" Camarena, and that charges should have been brought at the state rather than federal level. Federal prosecutors immediately appealed to the Supreme Justice Court of the Nation, which refused to rescind the lower court's decision. The Third Circuit Tribunal, also in Guadalajara, has now followed through by issuing Caro Quintero an amparo—a judicial order barring any federal action against him.
