El Mencho's Demise Unlikely to Halt Latin American Cocaine Flow

The recent killing of Nemesio Oseguera Cervantes, known as "El Mencho," the notorious leader of the Jalisco Cartel New Generation (CJNG), is not expected to significantly disrupt the flow of cocaine through Latin America to the United States. While El Mencho's death marks a major blow to the CJNG, the cartel's established network of strategic alliances across the region is robust enough to absorb the leadership change. The CJNG, a dominant force in Mexico's criminal underworld, has cultivated crucial partnerships with criminal organizations in Colombia, Ecuador, and Guatemala to facilitate its extensive cocaine trafficking operations.

These alliances are managed through a system of emissaries who oversee cocaine shipments, ensure product quality, and secure trafficking routes. Even with uncertainty surrounding the CJNG's future leadership, these operational relationships are anticipated to experience only temporary impacts. Colombia, the world's leading cocaine producer, remains a critical hub for the CJNG, which has fostered connections with Colombian criminal groups since its inception in 2010.

In 2024, Colombia reported 262,000 hectares of coca crops, with an estimated production capacity exceeding 3,000 metric tons of cocaine. Mexican cartels, including the CJNG, have historically been key clients for Colombian trafficking networks. The established system of emissaries negotiating and overseeing cocaine transport, particularly through the Pacific, highlights the deep-rooted and adaptable nature of these cross-border criminal enterprises.
