U.S. Actions Targeting Transnational Criminals for Illicit Fentanyl Activity – United States Department of State


Samuel Leon Alvarado is a fentanyl trafficker for the Sinaloa Cartel engaged in the movement of vast quantities of fentanyl from Mexico into the U.S. in pill and powder form.

Between Approximately 2017 and Approximately 2021, Ovidio Guzman Lopez, Samuel Leon Alvarado and another co-conspirator, worked with a third co-conspirator (CC-1), who was based in the U.S., to maintain multiple premises in the Los Angeles metropolitan area for the storage and wholesale distribution of the Sinaloa Cartel’s fentanyl sourced from the Chapitos.  In total, Ovidio Guzman Lopez, Leon Alvarado, and the other co-conspirator sent approximately 80 kilograms of fentanyl to CC-1 in the U.S. for storage and distribution.  CC-1 sold some of the fentanyl locally in Los Angeles, and using commercial parcel carriers, shipped fentanyl to, among other places, Ohio, Michigan, and Pennsylvania.

On April 4, 2023, a federal grand jury sitting in the Southern District of New York returned an indictment against Samuel Leon Alvarado and others charging them with engaging in a Fentanyl Importation Conspiracy, Fentanyl Trafficking Conspiracy, Possession of Machineguns & Destructive Devices, Conspiracy to Possess Machineguns & Destructive Devices, and Money Laundering Conspiracy.
