In 1980, DEA special agent
Enrique "Kiki" Camarena was assigned to the Administration's resident agency in
Guadalajara. Working through informants, Camarena discovered cartel marijuana plantations in
Zacatecas state. The plantations were raided and destroyed. In 1984, Mexican soldiers, backed by helicopters, destroyed an even larger marijuana plantation known as "Rancho Búfalo" in
Chihuahua, known to be protected by
Mexican DFS intelligence agents, as part of "Operation Godfather". Thousands of farmers worked the fields at Rancho Búfalo, and the annual production was later valued at 8 billion. All of this took place with the knowledge of local police, politicians, and the military. Camarena was beginning to expose the connections among drug traffickers, Mexican law enforcement, and high-ranking government officials within the
Partido Revolucionario Institucional (PRI), which Félix Gallardo considered to be a major threat to the Guadalajara cartel's operations throughout Mexico. after which, on February9, Camarena was executed. Autopsy results indicated that he died after his skull was perforated with a drill. He was injected with adrenaline and other stimulant drugs so as to be kept awake and to avoid his losing consciousness during his torture and interrogation. His body, wrapped in plastic, was found with that of pilot Alfredo Zavala Avelar, in a shallow hole on a ranch in Michoacan state. A special unit was dispatched to coordinate the investigation in Mexico, where corrupt officials were being implicated. Investigators identified Félix Gallardo and his two close associates, Ernesto Fonseca Carrillo and Rafael Caro Quintero, as the primary suspects behind the kidnapping. Under pressure from the US, Fonseca and Quintero were apprehended, but Félix Gallardo still enjoyed political protection. ==Arrest==
