The different Sinaloa Cartel factions fighting over control of drug smuggling routes in northern Mexico have been losing high-ranked members one by one as Mexican troops continue making advances.
Earlier this month, "Los Chapitos" lost their head of security and a right-hand man of Joaquín "El Chapo" Guzmán, while "La Mayiza" suffered a big blow to its ranks when "El Max", considered one of the greatest generators of violence in the country, was captured outside of Culiacán in late October.
