Sinaloa cartel co-founder 'El Mayo' Zambada sentenced to life without parole in Brooklyn federal court

Arrest and extradition

Ismael "El Mayo" Zambada, 76, was arrested in July 2024 after a private plane landed in El Paso, Texas. He later claimed that Joaquín Guzmán López, a son of his former partner Joaquín "El Chapo" Guzmán, had kidnapped him in Mexico and flown him to the United States against his will. Guzmán López, who was also taken into custody, subsequently confirmed the account. The arrest, carried out without clear prior coordination with Mexican authorities, drew sharp criticism from Mexico City.

The detention of El Mayo in 2024 was carried out on Mexican soil without it having been clarified what role US security agencies played.

Guilty plea and sentencing

Zambada pleaded guilty in August 2025 to charges including engaging in a continuing criminal enterprise and racketeering conspiracy, admitting responsibility for 85 underlying crimes. In exchange, federal prosecutors agreed not to pursue the death penalty. On Monday, US District Judge Brian M. Cogan imposed the mandatory life sentence without the possibility of parole. Cogan noted the scale of the operation left him little discretion.

The almost unimaginable amount of drugs attributable to him and the number of murders that we can document is enough to justify Congress's decision to make this a mandatory life sentence.

The court also ordered forfeiture of $15 billion, a sum prosecutors said reflects cartel profits under Zambada's leadership, though they acknowledged no assets have been identified or recovered.

Apology and prison conditions

Speaking in Spanish through an interpreter, Zambada apologized for the harm he caused and urged younger generations to avoid his path. He described growing up in an environment where violence seemed normal, but said that was no excuse. His attorney, Frank Perez, requested placement in a facility with adequate medical care, citing age-related health problems. Prosecutors countered that some prisons might not meet the security risks Zambada still poses, including the possibility he could continue directing cartel activities from behind bars.

A cartel empire dismantled

Zambada co-founded the Sinaloa cartel with El Chapo, building it into one of the world's most powerful drug trafficking organizations. While Guzmán was the public face, Zambada was considered the strategist, deeply involved in day-to-day operations, bribery of Mexican officials, and the orchestration of violence, including the murder of his own nephew. The cartel flooded the United States with tons of cocaine, heroin, fentanyl, and methamphetamine. Guzmán was convicted in 2019 and is serving life at the federal Supermax prison in Florence, Colorado. With Zambada's sentencing, both founders now face the same fate.

Diplomatic fallout

The case has strained US-Mexico relations. President Claudia Sheinbaum's government expressed frustration over the lack of transparency surrounding the 2024 arrest. US prosecutors, meanwhile, have signaled hope that Zambada's cooperation could expose corrupt Mexican officials who enabled the cartel's operations. The Sinaloa cartel is one of six Mexican drug gangs designated as Foreign Terrorist Organizations by the Trump administration.
