Mexican authorities confirmed the death of Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG), on Sunday, February 22, 2026. The operation, conducted in Tapalpa, Jalisco, resulted in a shootout that left six other cartel members dead and two arrested, according to the Mexican defense ministry.
Oseguera sustained serious injuries during the confrontation and died although being transferred by air to Mexico City. Authorities seized a significant arsenal, including rocket launchers capable of downing aircraft and destroying armored vehicles. The defense ministry stated that U.S. Authorities provided “complementary information” that aided in the operation.
The death of El Mencho triggered a wave of violence across Mexico. Armed groups responded by setting vehicles ablaze and blocking highways in over half a dozen states. In Guadalajara, Jalisco, charred vehicles were left at a damaged supermarket and on roads throughout the city. National Guards were deployed to patrol outside the General Prosecutor’s headquarters in Mexico City.
Flights were disrupted as panic spread at Guadalajara Airport, and a “Code Red” alert was issued in Jalisco, according to reports. The U.S. Government issued a security alert to its citizens in Mexico following the events.
El Mencho’s CJNG had risen to become a major international criminal enterprise, rivaling the Sinaloa Cartel, led by the imprisoned Joaquin “El Chapo” Guzmán. His death represents a significant victory for Mexico in its ongoing war on drug cartels, which are responsible for smuggling vast quantities of cocaine and fentanyl into the United States.
Mexican President Claudia Sheinbaum stated on social media that there was “absolute coordination with the governments of all states” and affirmed a commitment to “peace, security, justice, and the well-being of Mexico.”
The U.S. State Department has not yet issued a formal statement beyond the security alert, and the long-term implications of El Mencho’s death on the flow of narcotics and regional stability remain unclear.
