Security Secretary Omar García Harfuch revealed that the Cártel Jalisco Nueva Generación financed and supplied personnel to a faction of Los Chapitos in southern Sinaloa. The alliance ended with the killing of Nemesio Oseguera Cervantes, 'El Mencho', on February 22.
During the Tuesday June 16 morning press conference, García Harfuch detailed that the main link was direct between 'El Mencho' and the Sinaloa group. The CJNG provided financial resources and personnel reinforcements in that region.
The official clarified that there are no current indications that the relationship continues after the death of the CJNG leader. In August 2025, García Harfuch had denied the existence of that alliance.
'El Mencho' died during an Army operation at the Tapalpa Country Club in Jalisco. García Harfuch noted that the CJNG maintains defined regional leaders who have prevented an increase in violence in western Mexico.
