The brother of a late Mexican cartel founder backs a 20-year US prison term. A judge in Washington is due to set his sentence on Friday 13 November.
Antonio Oseguera Cervantes, nicknamed “Tony Montana”, backs a 20-year US prison term in a Washington drug case. He is the brother of the late Nemesio Oseguera Cervantes, known as “El Mencho”, who co-founded the Jalisco New Generation Cartel (CJNG).
He has not been sentenced, so 20 years is a recommendation and not a verdict. Judge Beryl Howell of the federal court in Washington is due to set his term on Friday, 13 November.
What His Defence Told the Court
On Tuesday, 3 November, his defence told the court it supports the 20-year recommendation of the probation office. That is 240 months, made up of 15 years on the drug count and five more on the firearms count.
The defence says he is 68 and has chronic illnesses, and it asks that he be held in a federal medical facility. It also says he has spent more than a year in near-total isolation in a jail in Alexandria, Virginia.
He wrote to the judge to express regret and to say he fears dying far from his family. His lawyers ask for mercy so that he might one day return home.
What He Pleaded Guilty To
The US Justice Department announced on Friday, 31 July that he pleaded guilty to two charges. One is conspiracy to distribute at least five kilograms of cocaine and 500 grams of methamphetamine for import into the United States.
The other is using and carrying a firearm to further that conspiracy. The law sets a 15-year minimum and a maximum of two consecutive life sentences.

What Prosecutors Allege About His Role
The Justice Department alleges he worked in the Milenio Cartel, an older drug gang, from about 2002 to 2010. It says he then worked directly under his brother in the CJNG from about 2010.
It alleges he obtained chemicals, supervised drug sales and handled proceeds, and that he laundered money through currency exchange businesses. It also says he carried a pistol to meetings and cash collections.
How the Case Reached a US Court
Mexico transferred him to the United States in February 2025 under its national security law, the Justice Department says. His brother died on Sunday, 22 February 2026, in a Mexican army operation in Jalisco state.
The United States designated the CJNG a foreign terrorist organisation in 2025. Oseguera’s charges are drug and firearms offences, not terrorism counts.
What It Means for You
The drugs named in the plea were destined for the United States, and a US court will decide the outcome. The case changes no US travel advisory, tariff or trade rule.
A sentence in Washington does not alter conditions in Jalisco or elsewhere in Mexico. For the wider picture, see our Mexico security guide and the guide to who holds power in Mexico.
More background is in our Mexico explainer, on the Mexico news page and on the Guadalajara city page. Guadalajara is the capital of Jalisco, where the CJNG is based.
What Is Not Known
The defence filing was not available to us, so its terms are as described in accounts of the document. One Mexican report says prosecutors seek 30 years, but no second source confirms it.
It is not known whether he cooperates with prosecutors or whether the judge will accept 20 years. He pleaded guilty only to the drug and firearms counts, and the wider descriptions of his role are allegations.
What Comes Next
Judge Howell is due to sentence him on Friday, 13 November. She may choose a term above or below the recommendation, within the limits of the law.
Until then, the 20-year figure is a recommendation that the defence supports, not a court order. The Justice Department has said the sentencing hearing is set for that date.
