Sinaloa co-founder 'El Mayo' sentenced to life without parole in US federal court
The 76-year-old cartel leader apologised in court before receiving a mandatory life sentence, marking a significant shift in the leadership structure of the Sinaloa organisation.

Ismael Zambada, widely known as 'El Mayo' and a co-founder of the Sinaloa cartel, has been sentenced to life in prison without the possibility of parole by a United States federal court. US District Judge Brian Cogan imposed the mandatory sentence on Tuesday, citing the vast quantity of illicit drugs and the number of documented murders attributable to Zambada’s leadership.
The 76-year-old pleaded guilty to charges including engaging in a continuing criminal enterprise and racketeering conspiracy, acknowledging culpability for 85 underlying crimes. In exchange for his guilty plea, prosecutors did not seek the death penalty. Judge Cogan stated that the almost unimaginable amount of drugs attributable to Zambada, alongside the documented murders, justified the mandatory life sentence mandated by Congress.
During proceedings on Monday, Zambada issued an apology in court, stating he grew up in an environment where violence and crime seemed normal but now recognised that this was no excuse. "There comes a time when every person must take responsibility for their decisions. I didn't, and many people paid the price," Zambada said. He further apologised for the harm caused and the example he set, urging future generations to choose a different path.
Zambada was arrested in July 2024 after claiming he was kidnapped in Mexico and flown to Texas. He was detained alongside Joaquin Guzman Lopez, the son of his former partner Joaquin "El Chapo" Guzman. While Guzman Lopez has pleaded guilty to federal drug charges, he has not yet been sentenced. His father, El Chapo, is already serving a life sentence at the federal Supermax prison in Florence, Colorado, having been convicted in 2019.
The arrest of Zambada has contributed to a significant splintering of the Sinaloa cartel, with loyalists now pitted against backers of Guzman’s sons, known as the "Chapitos". The Sinaloa cartel has been designated as a Foreign Terrorist Organization by US President Donald Trump. According to prosecutors, Zambada helped build the cartel into one of the world’s most powerful drug trafficking organisations, ordering torture and plotting murders, including the killing of his own nephew, while flooding the US with cocaine, fentanyl, and methamphetamine.
