Liborio Nunez Aguirre, a/k/a “Karateca,” 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.

Approximately March and April 2022, Nunez Aguirre negotiated the sale in the U.S. of approximately 70,000 fentanyl pills that Nunez Aguirre had trafficked into the U.S. on behalf of the Sinaloa Cartel.  During negotiations for the sale of those drugs, Nunez Aguirre stated that the fentanyl pills belonged to the Chapitos and that he could sell up to 500,000 fentanyl pills at one time.  The sale of 70,000 fentanyl pills were later completed in separate deliveries of 20,000 pills and 50,000 pills by associates working for Nunez Aguirre in Oceanside, California, in exchange for a total of $70,000.  The pills from both fentanyl sales were subsequently seized by the DEA.

On April 4, 2023, a federal grand jury in the Southern District of New York returned an indictment against Liborio Nunez Aguirre 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.
