In a significant blow to organized crime, Mexican armed forces confirmed the death of Nemesio Oseguera Cervantes, widely known as ‘El Mencho,’ during a military operation in Jalisco state on Sunday. The 59-year-old leader of the Jalisco New Generation Cartel (CJNG) sustained fatal injuries during an armed confrontation with soldiers near Tapalpa before succumbing en route to a Mexico City medical facility.
The operation, conducted with supplementary intelligence provided by United States authorities, represents one of Mexico’s most substantial victories in its prolonged campaign against drug cartels. Oseguera, who carried a $15 million bounty from U.S. authorities, ranked among Mexico’s most wanted criminals alongside recently captured Sinaloa Cartel leaders Joaquin ‘El Chapo’ Guzman and Ismael Zambada.
Retaliatory violence erupted across western Mexico following the operation, with CJNG militants blocking over twenty major transportation routes using burning vehicles. The widespread disruptions prompted Jalisco officials to cancel public events and suspend in-person educational activities. Violence subsequently spread to neighboring Michoacán state and the popular resort destination of Puerto Vallarta.
International responses included shelter-in-place advisories from the U.S. State Department for American citizens in affected regions, while Canadian authorities issued travel warnings citing ‘shoot-outs with security forces and explosions.’ Multiple airlines from both nations cancelled flights to Mexican destinations due to security concerns.
Mexican President Claudia Sheinbaum addressed the nation, urging calm while emphasizing federal coordination with state governments to restore order. The operation resulted in six additional cartel casualties and three soldiers wounded, according to official military statements.
