Core Event: Guilty Plea and Charges
Antonio Oseguera Cervantes, a 67-year-old Mexican national, pleaded guilty in a Washington federal court to conspiring to import cocaine and methamphetamine into the United States and to using a firearm in furtherance of that conspiracy. Prosecutors say he helped move at least 450 kg of cocaine and 45 kg of methamphetamine from January 1998 through December 2022. The plea carries a mandatory 15-year minimum, with a possible maximum of two consecutive life terms. U.S. District Judge Beryl Howell will sentence him in November 2026.
Background & Context: CJNG, “El Mencho,” and Terrorist Designation
Antonio’s brother, Nemesio Rubén Oseguera Cervantes (“El Mencho”), led the Cartel de Jalisco Nueva Generación (CJNG). El Mencho was killed by the Mexican army in February 2025, sparking unrest that left more than 70 dead, including 25 National Guard members, across 20 states. The Trump administration had designated CJNG as a foreign terrorist organization, expanding legal tools against it.
Before joining CJNG, Antonio was a member of the Milenio Cartel. Court filings describe his role from roughly 2002 to 2010 as overseeing narcotics sales, protecting territory, supervising meth labs, and procuring precursors. From 2010 onward he reported directly to his brother, supplying chemicals, distributing cocaine and meth, collecting proceeds, and managing money-laundering operations that moved funds from the United States to Mexico.

Official Statements & Responses
The Department of Justice announced the plea as part of the Homeland Security Task Force initiative established by Executive Order 14159. The investigation was conducted by the DEA’s Special Operations Division Bilateral Investigations Unit in Los Angeles, with the Justice Department’s Office of International Affairs facilitating the 2025 transfer. Prosecutors Lernik Begian, Douglas Meisel and Nicole Lockhart are handling the case.
Why It Matters
The plea highlights U.S.–Mexico law-enforcement cooperation in targeting senior cartel figures. Securing a conviction of a CJNG operative demonstrates the impact of the terrorist-organization designation and the task force’s focus on dismantling command and financial structures that fuel drug trafficking and violence.
What’s Next
Judge Beryl Howell will issue a sentence in November 2026. The Justice Department says the case will support further actions against CJNG leaders and reinforce bilateral enforcement mechanisms under the task-force framework.
