What had been an open secret for months was confirmed by the U.S. Drug Enforcement Administration's (DEA) in its 2025 report: an alliance between the Cártel Jalisco Nueva Generación (CJNG) and "Los Chapitos," a faction of the Sinaloa Cartel currently fighting for control in northern Mexico with "La Mayiza."
In its latest report, the DEA warned of a potential alliance between the two criminal groups. The agency said the Jalisco Cartel — led by Nemesio "El Mencho" Oseguera Cervantes — may be seeking to take advantage of the ongoing conflict between Los Chapitos and La Mayiza to expand its influence into parts of Sinaloa.
