• Ugandan national Michael Katungi Mpweire was extradited to the U.S. to face federal charges related to cocaine and arms trafficking.
• He is accused of conspiring to supply military-grade weapons, including AK-47s and rocket launchers, to the Mexican Cartel de Jalisco Nueva Generación (CJNG).
• The alleged conspiracy, which began in September 2022, involved co-defendants from Bulgaria, Kenya, and Tanzania, and discussed advanced weaponry valued at €53.7 million.
• The CJNG was designated a Foreign Terrorist Organization by the U.S. on February 20, 2025.
• Mpweire faces a mandatory minimum of 10 years and a maximum of life imprisonment if convicted, following an investigation aided by Ugandan authorities.

This prosecution highlights the increasing reach of international law enforcement and the effectiveness of extradition treaties, particularly between Uganda and the U.S., for serious transnational crimes like drug and arms trafficking.

A Ugandan national, Michael Katungi Mpweire, 45, has been extradited to the United States to face a series of federal charges in connection with an alleged international scheme involving cocaine distribution and the illicit supply of military-grade weapons. His initial appearance before a federal court in Alexandria, Virginia, took place on Thursday, October 8, following his transfer from Uganda. The U.S. Attorney's Office for the Eastern District of Virginia is prosecuting the case, which underscores the extensive reach of American law enforcement in combating transnational criminal enterprises.

Mpweire faces a three-count indictment, including conspiracy to distribute cocaine, conspiracy to possess firearms in furtherance of drug trafficking, and conspiracy to provide material support or resources to a designated foreign terrorist organization. These charges stem from an alleged plot that prosecutors contend began in September 2022, aiming to arm a notorious Mexican drug cartel. The severity of the accusations highlights the U.S. government's commitment to disrupting global networks that fuel both drug trafficking and terrorism.

The indictment details a complex conspiracy involving Mpweire and three co-defendants hailing from Bulgaria, Kenya, and Tanzania. This group allegedly sought to furnish Mexican drug cartels, specifically the Cartel de Jalisco Nueva Generación (CJNG), with a wide array of military-grade armaments. The arsenal purportedly included machine guns, rocket launchers, grenades, sniper rifles, anti-personnel mines, night-vision equipment, and anti-aircraft weapons, demonstrating the sophisticated nature of the alleged operation.

A key component of the alleged scheme involved arranging for the export of 50 automatic AK-47 rifles, complete with magazines and ammunition, from Bulgaria. This was to be facilitated by an end-user certificate obtained from Tanzania, which prosecutors claim falsely identified the intended recipient. The true destination for these weapons, according to the U.S. government, was the CJNG. Furthermore, the conspiracy reportedly evolved to encompass discussions about even more advanced weaponry, such as surface-to-air missiles, anti-aircraft drones, and the ZU-23 anti-aircraft weapon system, with the proposed package valued at approximately €53.7 million, equivalent to about US$58 million.

This case exemplifies robust international law enforcement collaboration, with the U.S. Drug Enforcement Administration's Special Operations Division leading the investigation. Significant assistance was also provided by the U.S. Department of War and various other international law enforcement agencies. Crucially, the U.S. Department of Justice acknowledged the vital cooperation extended by Ugandan authorities, including the Ministry of Justice and Constitutional Affairs and the Office of the Director of Public Prosecutions, which was instrumental in securing Mpweire's extradition.

The legal context of the charges is further defined by the U.S. designation of the Cartel de Jalisco Nueva Generación as a Foreign Terrorist Organization, a classification that took effect on February 20, 2025, according to the Justice Department. This designation elevates the severity of any alleged material support provided to the group. Meanwhile, separate legal proceedings are underway for Mpweire's co-defendants: Bulgarian national Peter Dimitrov Mirchev, accused of coordinating arms transactions, was arrested in Madrid, Spain, on April 8, 2025, and subsequently extradited to the United States on March 19, 2026. Kenyan national Elisha Odhiambo Asumo and Tanzanian national Subiro Osmund Mwapinga have both entered guilty pleas to charges of conspiracy to distribute and possess with intent to distribute cocaine, with their sentencing dates set for November 4, 2026, and January 13, 2027, respectively.

Should Michael Katungi Mpweire be convicted of the charges against him, he faces severe penalties under U.S. law. The potential sentence includes a mandatory minimum of 10 years in prison, with a maximum possible sentence of life imprisonment. Any actual sentence would be determined by a federal judge, who would consider applicable sentencing guidelines and other statutory factors. It is important to note that these charges remain allegations, and Mpweire is afforded the presumption of innocence unless and until proven guilty in a court of law.

This prosecution highlights the increasing reach of international law enforcement and the effectiveness of extradition treaties, particularly between Uganda and the U.S., for serious transnational crimes like drug and arms trafficking. The case serves as a stark reminder of the global efforts to dismantle criminal networks that threaten international security and public safety. The coordinated actions across continents demonstrate a unified front against organizations like the CJNG, which are increasingly targeted for their dual roles in drug distribution and destabilizing violence.

This case highlights the increasing reach of international law enforcement and the effectiveness of extradition treaties, particularly between Uganda and the U.S., for serious transnational crimes like drug and arms trafficking. Lawyers advising clients involved in international trade or with potential links to designated entities should be aware of heightened compliance risks and the potential for cross-border prosecution, even for actions initiated outside the prosecuting jurisdiction.
