Nearly eight months in, the internal conflict between "Los Chapitos" and "La Mayiza" continues to escalate. Tensions worsened recently when gunmen loyal to the faction led by the sons of Joaquín "El Chapo" Guzmán attacked a drug rehabilitation center in Culiacán, Sinaloa, in search of a rival ringleader tied to the faction led by Ismael Zambada Sicairos, the son of Ismael "El Mayo" Zambada.
The attackers killed eight patients, and according to one survivor, the death toll would have been higher if their weapons hadn't jammed. The indiscriminate attack is one of dozens since turf wars between the rival factions broke out last September, following the capture of "El Mayo" Zambada — an arrest his group claims was orchestrated by the "Chapitos."
