Mexico on High Alert After Jalisco Cartel Leader El Mencho Killed in Military Raid

Mexico is grappling with a heightened security crisis following the death of Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” the leader of the powerful Jalisco New Generation Cartel (CJNG). The operation, carried out by Mexican authorities in the state of Jalisco on February 22, 2026, triggered widespread violence, including vehicle arsons and disruptions to transportation, raising concerns about potential instability in the lead-up to the FIFA World Cup.

The Death of El Mencho and Immediate Aftermath

El Mencho, considered one of the world’s most wanted drug traffickers, was reportedly killed during a raid in Tapalpa, Jalisco. According to Spanish Wikipedia, he had led the CJNG since August 31, 2009, until his death on February 22, 2026. The immediate response to his death involved widespread arson attacks, with vehicles set ablaze in several cities, including Puerto Vallarta and Guadalajara.

The U.S. Embassy issued warnings to citizens in several Mexican states, advising them to shelter in place. Dutch citizens were also urged by their Ministry of Foreign Affairs to remain indoors in affected areas. Air travel was partially suspended at multiple airports, and public transportation in Jalisco largely ground to a halt. Governor Pablo Lemus declared a “code red” and prevented residents from leaving their homes.

The Jalisco Cartel: Structure and Influence

The CJNG, founded sixteen years ago in Jalisco, is active in over 700 municipalities across Mexico. The cartel is known for its paramilitary structure, utilizing ex-military personnel from Colombia and Guatemala. Bloomberg reports the cartel is responsible for the militarization of cartel violence through the utilize of drones, mines, and rocket launchers.

The CJNG is heavily involved in the trafficking of methamphetamine and cocaine to Europe and the United States, controlling a key cocaine smuggling route from Colombia via Ecuador to Mexico.

Succession and Potential for Increased Violence

The death of El Mencho creates a power vacuum within the CJNG. Experts warn that eliminating a leader often leads to increased violence as factions within the organization fight for control. Rival cartels may also attempt to exploit the situation, leading to territorial conflicts.

Succession within the CJNG is complicated by the fact that El Mencho’s son, a cartel commander, is serving a life sentence in the United States, and his brother, Antonio Oseguera Cervantes (alias “Scarface”), was extradited to the U.S. In February 2025. According to Spanish Wikipedia, El Mencho has several other brothers, including Juan, Abraham, Miguel, and Marin Oseguera Cervantes.

Cecilia Farfán-Méndez, an expert on organized crime at the Inter-American Dialogue, believes the security situation in parts of Mexico will likely deteriorate. She notes that eliminating a leader does not eliminate the organization itself and that international drug trafficking is unlikely to be significantly disrupted.

World Cup Security Concerns

With Guadalajara set to host matches during the FIFA World Cup in June, the Mexican government faces the challenge of ensuring the safety of the event. The recent violence raises questions about potential retaliation from the cartel before or during the tournament. The government will need to demonstrate its ability to maintain security and reassure the international community.
