What Happened to Cártel de Jalisco Nueva Generación (CJNG)?

The Cártel de Jalisco Nueva Generación (CJNG) emerged around 2009-2010 from the remnants of the Milenio Cartel, initially as an armed faction known as 'Los Torcidos' or 'Matazetas,' aiming to counter rivals like Los Zetas. Under the leadership of Nemesio Oseguera Cervantes, alias 'El Mencho,' the CJNG rapidly expanded its territorial control across Mexico, becoming one of the country's two most dominant cartels. Its aggressive growth strategy was fueled by the high demand for Mexican methamphetamine, heroin, and fentanyl in the U.S., and it quickly diversified into other illicit markets such as fuel theft, extortion, kidnapping, and human trafficking.

Key turning points in the CJNG's trajectory include the gruesome Veracruz Massacre in 2011, which signaled its brutal intent, and its formal separation from the Sinaloa Cartel in 2014, leading to widespread conflicts with former allies and other rival groups. The cartel is notorious for its extreme violence, including public executions, mass graves, and the use of advanced weaponry and tactics. In May 2015, the CJNG notably shot down a Mexican military helicopter with a rocket-propelled grenade during an attempt to capture El Mencho, marking a significant escalation in its confrontation with state forces.

The U.S. government has increasingly focused on the CJNG, designating it as a Foreign Terrorist Organization (FTO) and a Specially Designated Global Terrorist entity in February 2025, reflecting its significant threat to national and transnational security. This designation was followed by intensified enforcement actions, including sanctions against CJNG-linked financial networks and businesses. The cartel, however, continued to adapt, demonstrating insurgent-style tactics such as deploying improvised explosive devices (IEDs) against security forces in May 2025 and using explosive-laden drones in October 2025.

The most significant recent development occurred on February 22, 2026, when Mexican security forces, with U.S. intelligence support, killed 'El Mencho' during an operation in Tapalpa, Jalisco. His death triggered a wave of retaliatory violence across at least 20 Mexican states, including widespread road blockades, vehicle arsons, and attacks on security forces, resulting in numerous casualties. In the aftermath, U.S. authorities identified Juan Carlos Valencia González, alias 'El 03,' El Mencho's stepson, as the new leader, though the cartel's leadership structure is reportedly in a state of flux.

As of July 2026, the CJNG remains a formidable criminal threat, actively engaged in drug trafficking to the United States, Australia, Canada, and countries in Africa, Asia, Central and South America, and Europe. It continues to exert dominance in key Mexican states like Jalisco, Nayarit, and Colima, controlling strategic points like the Port of Manzanillo for importing precursor chemicals. Mexican authorities continue to target its operations and leadership, with recent arrests of alleged high-ranking members and ongoing efforts to dismantle its financial networks, including fuel smuggling and money laundering schemes. The cartel's ability to maintain its operational strength and expand, despite leadership changes and enforcement pressure, underscores its resilience and adaptive nature.
