Ismael "El Mayo" Zambada, the 76-year-old former Mexican drug kingpin, was sentenced to life in prison by a U.S. court on Monday. The sentencing in Brooklyn federal court serves as the final chapter in a yearslong U.S. government effort to capture and prosecute the long-elusive leader of the Sinaloa cartel. This ruling comes seven years after his co-founder, Joaquín "El Chapo" Guzmán, received an identical life sentence. U.S. District Judge Brian Cogan imposed the life term without the possibility of parole, citing Zambada's leadership in a "continuing criminal enterprise" and his involvement in racketeering violations.
Speaking through a Spanish-language interpreter, Zambada addressed the court directly. "No one wins in a war like this," he said, offering an apology for the harm he caused and the example he set. He encouraged future generations to choose a different path, emphasizing that the violence must end. "In Mexico and elsewhere affected by this type of crime, too many lives are lost, too many families are destroyed, and too many young people are trapped in a cycle that leads only to prison or death," he stated. In addition to the prison term, Zambada faces $15 billion in financial penalties, which prosecutors described as proceeds from the cartel's criminal activities under his command.
U.S. Attorney for the Eastern District of New York Joseph Nocella, Jr. remarked that Zambada spent nearly four decades poisoning American communities to generate billions in profit while ordering the murders of anyone who stood in his way. Prosecutors characterized Zambada as the cartel's primary strategist and dealmaker, noting that he was more deeply involved in the organization's day-to-day operations than the more flamboyant Guzmán, who is currently serving his life sentence at the federal Supermax prison in Florence, Colorado. During his guilty plea in August 2025, Zambada accepted responsibility for 85 underlying crimes, admitting that from 1980 until his arrest, he and his cartel were responsible for transporting at least 1.5 million kilograms of cocaine, most of which was destined for the United States.
The government's sentencing memo described Zambada as one of the most prolific and powerful narcotraffickers in history, noting that the magnitude of the corruption and violence he spread globally is difficult to overstate. Zambada admitted that his organization built extensive relationships with cocaine producers in Colombia, managed the importation of drugs into Mexico via boat and plane, and smuggled them across the U.S.-Mexico border. He further acknowledged that his subordinates paid massive bribes to Mexican officials to ensure the cartel could operate without interference. Prosecutors also highlighted his history of ordering torture and murder, including the 2024 killing of his nephew, Eliseo Imperial Castro, known as "Cheyo Antrax," after discovering Castro was pocketing money meant for the cartel.
In 2023, Zambada directed retaliatory violence that resulted in at least three deaths following the theft of a large cache of fentanyl, methamphetamine, and cocaine from the cartel. Prosecutors also alleged that he engaged in the systematic assassination of police, military personnel, and rival cartel members. Zambada was arrested in 2024 after he claimed he was kidnapped in Mexico, beaten, tied up, and flown to Texas by Joaquín Guzmán López, one of the sons of "El Chapo." This event triggered intense fighting in Sinaloa between Zambada's loyalists and the faction led by Guzmán's sons, known as the Chapitos. The U.S. Justice Department has previously alleged that the Chapitos and their associates utilized brutal torture methods, including electrocution and the use of hot chiles, against their rivals.
Defense attorney Frank Perez had argued against sending Zambada to the same Supermax facility as Guzmán, citing his client's guilty plea and acceptance of responsibility as a distinguishing factor. While judges often make recommendations regarding incarceration, the final decision rests with the federal Bureau of Prisons. Meanwhile, the circumstances of his capture remain a point of diplomatic tension. Earlier this month, the Mexican government announced it was investigating whether its sovereignty was violated during the operation. Mexican government secretary Rosa Icela Rodriguez noted that the U.S. Embassy had previously stated no U.S. agency participated in the capture, yet the FBI later displayed the plane used in the operation. "The versions are contradictory. Someone lied," Rodriguez said.
Along with a life sentence, he also faces $15 billion in financial penalties, which prosecutors said reflected proceeds from the cartel's crimes under his leadership.
In 2010, he gave a rare interview to the Mexican magazine Proceso, revealing that the Mexican army had come close to capturing him four times.
