The leader of the notorious Jalisco New Generation Cartel (CJNG) , Nemesio Rubén Oseguera Cervantes , better known as “El Mencho,” was killed on Sunday, February 22, 2026, by Mexican security forces during a military operation in the state of Jalisco . This announcement was confirmed by Mexican authorities after months of pursuit and under pressure from the United States, which had offered up to $15 million for his capture.

“El Mencho”, considered one of the world’s most wanted drug traffickers and an emblematic figure of organized crime, led the CJNG, a criminal organization that established itself as one of the most powerful in the country and exported cocaine, fentanyl and other drugs to the United States and internationally.

According to official reports, the security operation that led to his death took place in Tapalpa , in the highlands of Jalisco, where federal forces clashed with suspected cartel members. “El Mencho” was seriously wounded during the confrontation and died while being airlifted to Mexico City .

The CJNG's response was swift. In the hours following the announcement, scenes of violence and chaos were reported in several states , with road blockades , vehicles and businesses set ablaze , and attacks against security forces. Incidents were reported in at least six states, including Jalisco, Michoacán, Colima, Guanajuato, Tamaulipas, and Aguascalientes .

In response to the scale of the violence, authorities have declared a "code red" in certain regions, notably Jalisco, urging residents to stay home and avoid areas affected by the clashes. Significant disruptions have also been reported in transportation, with flight cancellations and security advisories issued by foreign governments for their citizens in the affected areas.

This operation is considered one of the most significant blows dealt to organized crime in Mexico in decades , and El Mencho's death could reshape the balance of power within the cartel world. However, the ensuing violence demonstrates the potential for reprisals and instability the country could face in the coming days.
