 Félix Gallardo still planned to oversee national operations, he had the contacts so he was still the top man, but he would no longer control all details of the business; he was arrested on April 8, 1989.It is also believed that Amado Carrillo Fuentes was once a part of the Guadalajara Cartel, but he was sent to Ojinaga, Chihuahua to oversee the cocaine shipments of his uncle, Ernesto Fonseca Carrillo, and to learn about border operations from Pablo Acosta Villarreal, "El Zorro de Ojinaga" ("The Ojinaga Fox").Once Acosta and his successor Rafael Aguilar Guajardo were murdered, Carrillo took over the control of the Juárez Cartel.
