Antonio Oseguera Cervantes, a Mexican cartel figure known as “Tony Montana”, has been sentenced in the United States to 270 months in prison for international drug trafficking and a related firearm offence.
Oseguera Cervantes, 67, had pleaded guilty to conspiring to distribute at least five kilograms of cocaine and 500 grams of methamphetamine for importation into the United States. He also admitted using, carrying and possessing a firearm in furtherance of the conspiracy.
Federal prosecutors said he first worked with the Milenio Cartel and later with the Cartel de Jalisco Nueva Generación. Their sentencing account described his roles as overseeing drug sales, maintaining methamphetamine laboratories, collecting proceeds and laundering money.
He is the brother of Nemesio Oseguera Cervantes, known as “El Mencho”, who co-founded and led CJNG. The government said Antonio reported to his brother and worked with the aligned Los Cuinis organisation.
The prosecution followed Antonio Oseguera Cervantes’s transfer from Mexico to the United States in February 2025 under Mexico’s national security law. US authorities credited Mexico with securing his presence for trial, making the case a cross-border prosecution rather than an extradition contest resolved in the sentencing judgment.
The 270-month term is the final district-court sentence on the admitted offences. The announcement does not state that an appeal has been filed. Any later appellate challenge would address the conviction or sentence through the federal courts; it would not alter the present effect of the judgment unless relief were granted.
The case combines a narcotics-conspiracy conviction with the distinct firearm count. That second offence reflects the admitted connection between the weapon and the trafficking enterprise, rather than a standalone allegation that remained to be tried.
