The battle eventually resulted in defeat for the Juárez Cartel but not before taking the lives of between 5000 to 12,000 people in drug-related violence.  During the war for the turf in Ciudad Juárez the Sinaloa Cartel used several gangs (. Los Mexicles , the Artistas Asesinos and Gente Nueva ) to attack the Juárez Cartel.  The Juárez Cartel similarly used gangs such as La Línea and the Barrio Azteca to fight the Sinaloa Cartel.
