Mexican drug lord Ismael Zambada García, known as “El Mayo”, was sentenced to life in prison in a US federal court on Monday after a plea deal last year in which he admitted to shipping vast amounts of cocaine and other substances as leader of the violent Sinaloa cartel. The sentencing took place in Brooklyn, New York, before US District Judge Brian Cogan, who also presided over the trial of fellow cartel leader Joaquín “El Chapo” Guzmán.
Background and charges
Zambada, 76, helped co-found and lead the Sinaloa cartel, becoming one of the most wanted targets for US intelligence and law enforcement agencies for decades. He signed a plea deal last August, admitting charges including racketeering conspiracy and continuing criminal enterprise, after the US Justice Department agreed not to seek the death penalty. The US government is also seeking $15 billion as part of his punishment.
Prosecutors accused him of trafficking tons of cocaine, marijuana, heroin, and fentanyl to the US and other parts of the world. They also alleged he was a leader of a violent organization that corrupted Mexican politicians, military officials, and law enforcement agents.
El Mayo’s role and arrest
While El Chapo was the more visible face of the Sinaloa cartel, El Mayo was regarded as the elusive, behind-the-scenes leader running operations, maintaining a low profile with few public sightings. His arrest in the US in 2024 came as a surprise, following a mysterious operation in which he was beaten and kidnapped by one of El Chapo’s sons, Joaquín Guzmán López, and flown across the border to New Mexico, where he was arrested by US federal agents. It remains unclear whether US agencies facilitated the cross-border kidnapping. Guzmán López pleaded guilty in an abduction case and has become a cooperating witness.
Impact on cartel and US-Mexico relations
El Mayo’s arrest led to a splintering of the Sinaloa cartel, with his son and El Chapo’s sons leading different factions in a violent inner-cartel battle for territory that has ravaged parts of Mexico. His sentencing comes at a tense time in US-Mexico relations, as the Trump administration has escalated pressure on Mexico to crack down on criminal groups. Last year, the Trump administration designated the Sinaloa cartel as a terrorist group and has threatened US military intervention.
Lawyer’s request and security concerns
Frank Perez, a lawyer for El Mayo, said in a 6 July court filing that his client was fully aware he would receive a life sentence when he decided to accept responsibility. Perez asked Judge Cogan to recommend to the US Bureau of Prisons that his client, as a septuagenarian, be placed in a facility with adequate medical care. However, prosecutors with the Brooklyn US attorney’s office argued that the suggested prisons may not be equipped to handle the security concerns posed by Zambada, including the possibility he could continue to direct cartel activities from behind bars. “Those security concerns will continue for the foreseeable future because individuals loyal to the defendant continue to control the cartel,” prosecutors wrote in a 13 July filing.
El Chapo is serving his life sentence at a maximum-security prison in Colorado.
