The group that won out eventually became what is now the CJNG, assuming control of drug operations in the area. Juggling interests from China to North Africa and eastern Europe, the CJNG’s bloody advance has helped push homicides to their highest levels under President Enrique Peña Nieto, who vowed to restore law and order when he took office in late 2012.
Intimidating, paying off, or eliminating police, CJNG leaders have ruthlessly applied lessons learned during their apprenticeship under Guzmán’s cartel to muscle in on battered rivals and snatch trafficking routes, security experts say.
