Rosalinda González Valencia: The Quiet Power Behind Mexico’s CJNG Cartel

Rosalinda González Valencia, known as "La Jefa," has emerged as a pivotal figure in the Jalisco New Generation Cartel (CJNG), despite her low-profile demeanor. While her husband, Nemesio Oseguerra Cervantes, alias "El Mencho," was one of Mexico's most sought-after criminals before his death in February 2026, González Valencia has long been a key player in the cartel's operations. Her strategic marriage to El Mencho fused her family's money laundering network, Los Cuinis, with the CJNG's criminal infrastructure, propelling the group's rise in power and influence.

González Valencia's roots trace back to a family of criminals. Her uncle, Armando Valencia González, founded the Milenio Cartel, drawing many family members into the drug trade. The family transitioned from avocado farming to marijuana and opium poppy cultivation in the 1990s, leveraging connections with the Sinaloa Cartel and Chinese pharmaceutical partners to expand their operations. This foundation allowed Los Cuinis to evolve into a sophisticated transnational money laundering network, further solidifying the CJNG's financial footing.

As the alleged chief financial operator of the CJNG, González Valencia oversaw approximately 73 front companies used to launder over $65 million. Her role highlights the growing influence of women in organized crime, including figures like Guadalupe Fernandez Valencia and Marllory Chacón, who have similarly managed vast illicit financial networks. Her leadership underscores the critical role of female operators in sustaining and expanding cartel activities, even as their contributions often remain behind the scenes.
