The recent death of Nemesio Oseguera, widely known as 'El Mencho', has been portrayed by authorities in both Mexico and the United States as a significant blow to organized drug crime. El Mencho led the Jalisco New Generation Cartel (CJNG), making him one of the most wanted criminals in both countries. His demise occurred during a coordinated operation that took place in Tapalpa, Jalisco, with collaboration from U.S. authorities. This event opens up discussions on the potential repercussions for drug trafficking dynamics, particularly in Brazil.

According to Roberto Uchôa, a former police officer and researcher at the University of Coimbra's Center for Social Studies, the operation that targeted El Mencho could create challenges in Brazil. The PCC (Primeiro Comando da Capital), one of Brazil's most powerful criminal factions, may begin to capitalize on the void left by the CJNG as it attempts to navigate internal struggles for succession. Uchôa suggests that such a power shift could lead to increased conflict, as various factions vie for control over lucrative drug trafficking routes and market shares.

Uchôa specifically notes that the PCC has already been involved in areas where the CJNG may be weakened, including the trafficking of synthetic drugs and cocaine into Europe. The implications of this change in dynamics could lead to a rise in violence and competition among criminal organizations in Brazil as they seek to fill the gaps in the drug trade left by the CJNG's difficulties. This situation underscores the interconnected nature of international drug trafficking and the potential consequences of leadership changes within major cartel structures.
