Former Mexican drug kingpin Ismael "El Mayo" Zambada was sentenced in a U.S. court Monday to life in prison, seven years after his Sinaloa cartel co-founder Joaquín "El Chapo" Guzmán was handed the same sentence. Zambada's sentencing in Brooklyn federal court was the culmination of the U.S. government's yearslong fight to bring the long-elusive cartel leader to justice. "If there's one thing I can say that has value today, it's this: the violence must end," the Sinaloa cartel co-founder said. Zambada ordered torture and plotted murders as he and co-founder Joaquín "El Chapo" Guzmán grew the Sinaloa cartel into the world's largest drug trafficking organization, federal prosecutors said. According to U.S. prosecutors, Zambada also engaged in "systematic assassinations" of fellow cartel members, police and the military.
