Mexican Drug Lord ‘El Mayo’ Enters Guilty Plea for U.S. Drugs Charges

El Mayo Zambada Pleads Guilty in Sinaloa Cartel case

MEXICO CITY – Ismael “El Mayo” Zambada, the founder of the Sinaloa Cartel, entered a guilty plea to two drug smuggling and conspiracy charges in a New York court, bringing an end to a notorious criminal career spanning decades.

Zambada, once considered the most powerful drug lord in the world, oversaw the transport of vast quantities of heroin, cocaine, and methamphetamine into the United States. His organization, the Sinaloa Cartel, achieved unparalleled reach globally.

The change in plea comes after years of claiming innocence and following a recent attempt on his life by rivals. Last year, Zambada was arrested in Texas after a double-cross orchestrated by the sons of his former ally, Joaquín “El Chapo” Guzmán.

Federal prosecutors had taken the death penalty off the table, which likely pushed Zambada towards a plea bargain to secure a more lenient sentence, possibly considering his age and health.

The guilty plea arrives as other members of the Guzmán family are also navigating plea deals. Seventeen Guzmán family members were escorted into the U.S. in May,and Ovidio Guzmán,Chapo’s son,pleaded guilty to drug smuggling charges in Chicago last month.

While more shadowy than the flamboyant El Chapo, known for his high-profile escapes, Zambada’s influence was equally devastating. He is expected to be sentenced in January 2026.
