El Mencho: The Fall of a Cartel Kingpin and the Future of CJNG

Nemesio Oseguera Cervantes, known as “El Mencho,” the founder of the Jalisco Cartel – New Generation (CJNG), was killed in a Mexican military operation on February 22, 2026. His death marks a significant moment in Mexico’s ongoing struggle against drug cartels, but experts warn that the CJNG is likely to survive, potentially evolving into a more decentralized and internationally-focused criminal organization.

The Rise and Reign of El Mencho

El Mencho established the CJNG in 2009, and under his leadership, it rapidly grew into one of the most violent and powerful drug cartels in Mexico [1]. Prior to forming the cartel, Oseguera Cervantes had a background in law enforcement [4]. The CJNG became known for its aggressive tactics and a substantial military-style arsenal.

The Military Operation and Aftermath

The operation that led to El Mencho’s death involved US intelligence support [3]. He died from wounds sustained in a firefight while being transported to Mexico City. The operation resulted in the deaths of at least 70 people, including cartel members and National Guard troops [3]. Following the operation, CJNG members responded with roadblocks, arson attacks targeting buses, vehicles, and petrol stations, and disruptions to air travel and education across multiple states [3].

The Future of CJNG: A Decentralized Model

Despite El Mencho’s death, experts believe the CJNG is likely to endure. The cartel may transition to a decentralized “criminal franchise model” with an international presence [3]. This structure could allow the cartel to continue operating effectively even without a single, central leader.

Impact and Implications

The death of El Mencho represents a blow to the CJNG, but it does not guarantee increased safety in Mexico [2]. The cartel’s potential shift towards a decentralized model and its existing international reach pose ongoing challenges for law enforcement agencies both within Mexico and abroad.
