TAPALPA, JALISCO – In a significant blow to Mexico’s criminal landscape, Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG), was killed in a military operation on February 22, 2026, in Tapalpa, Jalisco. The operation, detailed in a statement released by the Secretaría de la Defensa Nacional (SEDENA), marks a major escalation in the Mexican government’s ongoing efforts to dismantle powerful drug cartels and restore security across the country. The death of “El Mencho” represents a pivotal moment in the Mexican drug war, though the full impact remains to be seen.
The operation, a coordinated effort involving the Mexican Army, Air Force, National Guard, and intelligence agencies, was likewise supported by intelligence sharing with United States authorities, according to SEDENA. Forces Speciales del Ejército Mexicano planned and executed the operation, utilizing various aircraft from the Fuerza Aérea and the Fuerza Especial de Reacción Inmediata of the Guardia Nacional. The objective was the apprehension of Oseguera Cervantes, who had long been operating from a stronghold in the Jalisco region. The operation underscores the increasing collaboration between Mexican and U.S. Law enforcement in combating transnational criminal organizations.
Operation Details and Casualties
According to the official statement, military personnel came under attack during the operation, prompting a response in self-defense. The ensuing confrontation resulted in the deaths of seven individuals, including Oseguera Cervantes. Three CJNG members died at the scene, while three others, critically wounded, succumbed to their injuries during transport to Mexico City for medical attention. Authorities have stated that forensic activities are underway to confirm the identity of Oseguera Cervantes, though initial reports strongly indicate his death. Two additional CJNG members were detained, and a significant cache of weaponry, including rocket launchers capable of downing aircraft and destroying armored vehicles, was seized.
The operation was not without cost to Mexican security forces. Three members of the military were injured during the firefight and are receiving medical care in Mexico City. The SEDENA statement emphasized the commitment of the Ejército, Fuerza Aérea, and Guardia Nacional to strengthening security throughout Mexico.
U.S. Collaboration Confirmed
The Mexican Secretary of National Defense confirmed that the United States provided complementary intelligence that aided in the planning and execution of the operation. This collaboration highlights the ongoing security partnership between the two countries, particularly in addressing the threat posed by powerful cartels like the CJNG. The extent of U.S. Involvement beyond intelligence sharing remains unclear, but the confirmation underscores the importance of cross-border cooperation in disrupting criminal networks.
Nemesio Oseguera Cervantes, born July 17, 1966, had led the CJNG since 2009, transforming it into one of the most powerful and violent cartels in Mexico. According to a Wikipedia entry, he was known by several aliases, including “El Señor de los Gallos” and “El Mata Zetas.” His leadership was marked by a ruthless expansion of the cartel’s territory and influence, challenging the dominance of other established criminal organizations.
Regional Security Response
In the wake of the operation, Mexican authorities are reinforcing security measures in Jalisco and surrounding states. Elements of the National Guard and the Army are being deployed from central Mexico and neighboring regions to bolster security and prevent retaliatory actions by the CJNG. This increased military presence aims to maintain order and protect civilians in the region. The potential for violence remains high, and authorities are on alert for any attempts by the cartel to destabilize the area.
The operation in Tapalpa follows a period of heightened cartel activity in Jalisco, including reports of clashes, explosions, and arson attacks. The Wikipedia entry for the 2026 Jalisco operation details the widespread violence that erupted following the initial confrontation, indicating the cartel’s willingness to engage in open conflict with security forces.
The death of “El Mencho” is expected to trigger a power struggle within the CJNG, potentially leading to further fragmentation and violence. While the immediate impact remains uncertain, Mexican authorities are committed to maintaining pressure on the cartel and preventing the emergence of new leaders. The coming weeks and months will be critical in assessing the long-term consequences of this operation and its effect on the broader security landscape in Mexico.
Authorities have not yet announced details regarding funeral arrangements or investigations into potential accomplices. Further updates will be provided as they become available.
