The Fall of ‘El Mencho’: A Turning Point in Mexico’s Drug War?
The death of Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” leader of the Jalisco New Generation Cartel (CJNG), marks a significant moment in Mexico’s ongoing struggle against drug trafficking. Killed in a military operation on February 22, 2026, the 59-year-aged cartel boss had become one of the most wanted men in Mexico and the United States, with a $15 million reward offered for information leading to his capture.
From Illegal Immigrant to Drug Lord
El Mencho’s journey to becoming a kingpin began with his emigration to the United States in the 1980s. He faced multiple arrests and deportations for drug-related offenses, returning to Mexico where he eventually joined the Milenio Cartel. Internal conflicts led to his departure from Michoacan and he later co-founded Matazetas, a group notorious for its brutality against Los Zetas.
The Rise of the CJNG
In 2009, Oseguera established the CJNG, which rapidly grew to become one of Mexico’s most powerful criminal organizations, particularly after the arrests of Joaquin “El Chapo” Guzmán and Ismael “El Mayo” Zambada. The CJNG distinguished itself through its extensive network of hitmen and its capacity to manufacture its own weaponry. The cartel expanded its operations across numerous Mexican states and was designated a terrorist organization by the U.S. Department of State in 2025, accused of fentanyl trafficking, migrant smuggling, and other criminal activities.
A Legacy of Violence and Intimidation
Unlike some cartels that employ violence defensively, El Mencho was described as having a “violent nature” and a willingness to challenge all levels of government. This aggressive approach was demonstrated in a brazen 2020 attack on the then-Head of Police of Mexico City, Omar Garcia Harfuch, and in a 2015 ambush in Jalisco where CJNG members used rocket-propelled grenades to shoot down a military helicopter, resulting in the deaths of dozens of police officers and soldiers.
Family Ties and Criminal Networks
Oseguera’s family was also deeply involved in the cartel’s operations. His wife, Rosalinda Gonzalez Valencia, was released from prison last year after serving time for suspicious financial transactions linked to a car wash. His son, Rubén Oseguera González, known as “El Menchito,” received a life sentence in the United States for drug and weapons offenses.
Immediate Aftermath and Regional Instability
The immediate aftermath of El Mencho’s death saw widespread violence and disruption across Mexico. Roadblocks were established in Jalisco and other states, with vehicles set ablaze. The U.S. And Canada issued travel warnings to their citizens, advising them to shelter in place due to the escalating security situation.
What Does the Future Hold for the CJNG?
The death of El Mencho creates a power vacuum within the CJNG, raising questions about the cartel’s future trajectory. Several scenarios are possible:
Internal Power Struggles
A fierce internal struggle for leadership is likely. Potential successors may include high-ranking members of the cartel, leading to fragmentation and increased violence as factions vie for control. This could destabilize regions where the CJNG has a strong presence.
Increased Fragmentation of Cartels
The CJNG’s decline could lead to a broader fragmentation of Mexico’s drug cartels, with smaller, more localized groups emerging. This could make it more difficult for law enforcement to track and disrupt criminal activity.
Shift in Drug Trafficking Routes
The disruption of the CJNG’s operations may prompt a shift in drug trafficking routes, potentially leading to increased violence in other regions as rival cartels attempt to fill the void.
Enhanced Government Crackdown
The Mexican government may capitalize on this opportunity to intensify its crackdown on organized crime, potentially leading to further arrests and seizures of assets. However, this could also escalate violence as cartels resist government efforts.
