Death of CJNG Leader Sparks Chaos Across Mexico as Government Signals Major Breakthrough.
The Mexican military has killed Nemesio Rubén Oseguera Cervantes, widely known as “El Mencho,” the powerful leader of the Jalisco New Generation Cartel. According to official reports, he was wounded during a military operation in Tapalpa, Jalisco, and later died while being transported to Mexico City.
Oseguera Cervantes headed the Jalisco New Generation Cartel, one of Mexico’s most dominant and violent criminal organizations. His death marks the most significant blow against organized crime in Mexico since the recapture of Joaquín “El Chapo” Guzmán nearly a decade ago.
The operation immediately triggered violent retaliation across multiple states. Cartel members reportedly set vehicles ablaze, blocked highways, and clashed with security forces. In cities such as Guadalajara, residents sheltered indoors as gunfire and arson attacks spread panic. Schools in several states canceled classes, and airport operations were disrupted due to staffing shortages amid the unrest.
Authorities confirmed multiple casualties during the clashes. Security personnel were killed in Tapalpa, Zapopan, Puerto Vallarta and Guadalajara. Several troops were injured, and numerous suspects were arrested. The military seized heavy weaponry, including armored vehicles and rocket launchers, underscoring the cartel’s firepower.
Security analysts described the killing as a turning point in Mexico’s campaign against organized crime. Some believe it strengthens the government’s position in ongoing security cooperation discussions with the United States. U.S. President Donald Trump posted a cryptic message on Truth Social stating, “We’re winning too much, it’s just not fair,” fueling speculation about the broader geopolitical implications.
Experts warn that the aftermath could prove volatile. If Oseguera Cervantes’ relatives assume control, violent reprisals may intensify. Alternatively, rival factions could compete for dominance, potentially fragmenting the cartel’s structure.
A former police officer who later rose through the ranks of organized crime, Oseguera Cervantes built the CJNG into a global trafficking network after breaking from the Milenio Cartel and challenging the Sinaloa Cartel. His rise reshaped Mexico’s criminal landscape, and his death now opens an uncertain chapter in the country’s security battle.
