Following the death of its leader, Nemesio Oseguera, alias "El Mencho," the powerful Jalisco Nueva Generación (CJNG) cartel demonstrated its extensive reach and violent capabilities by orchestrating roadblocks and arsons across multiple Mexican states, including Jalisco, Michoacan, Puebla, Sinaloa, Guanajuato, and Guerrero, and even impacting the resort town of Puerto Vallarta. The United States had offered a $15 million reward for El Mencho, who founded the cartel in 2009, transforming it into one of Mexico's most formidable drug trafficking organizations, surpassing Sinaloa in expertise and armament. The CJNG is a major supplier of heroin, cocaine, methamphetamine, and fentanyl to the U.S. and engages in extortion, fuel theft, and human trafficking, consistently challenging the Mexican government with extreme violence, including assassination attempts and massacres. While the government's operation to eliminate El Mencho is considered a tactical success, the cartel's future is uncertain, with potential for continued operations or internal power struggles in the absence of a clear successor.
