Rosalinda González Valencia, wife of CJNG leader El Mencho, was arrested in Mexico amid claims he died the day before.

A significant blow to the cartel's leadership came when Rosalinda González Valencia, the wife of CJNG leader Nemesio "El Mencho" Oseguera Cervantes, was detained in Zapopan, Mexico, during a military operation. Known as "La Jefa," she was connected to the money laundering organization Los Cuinis, which used legitimate companies to finance the CJNG. El Mencho was reportedly killed in a Mexican military operation on February 22, 2026, and this arrest comes after her brothers and children were detained. The family's financial activities, which are still essential to the cartel's worldwide influence despite continuous disruptions, have long been the focus of the U.S. DEA's attention.
