LOS ANGELES, JULY 4 -- The Central Intelligence Agency trained Guatemalan guerrillas in the early 1980s at a ranch near Veracruz, Mexico, owned by drug lord Rafael Caro Quintero, one of the murderers of U.S. drug agent Enrique "Kiki" Camarena, according to a Drug Enforcement Administration report made public here.

The report is based on an interview of two Los Angeles-based DEA agents that was conducted with Laurence Victor Harrison, who, according to court testimony, ran a sophisticated communications network for major Mexican drug traffickers and their allies in Mexican law enforcement in the early- and mid-1980s.

On Feb. 9, according to the report, Harrison told DEA agents Hector Berrellez and Wayne Schmidt that the CIA used Mexico's Federal Security Directorate, or DFS, "as a cover, in the event any questions were raised as to who was running the training operation."

Harrison also said that "representatives of the DFS, which was the front for the training camp, were in fact acting in consort with major drug overlords to ensure a flow of narcotics through Mexico into the United States."

At some point between 1981 and 1984, Harrison said, "members of the Mexican Federal Judicial Police arrived at the ranch while on a separate narcotics investigation and were confronted by the guerrillas. As a result of the confrontation, 19 {Mexican police} agents were killed. Many of the bodies showed signs of torture; the bodies had been drawn and quartered."

In a separate interview last Sept. 11, Harrison told the same two DEA agents that CIA operations personnel had stayed at the home of Ernesto Fonseca Carrillo, one of Mexico's other major drug kingpins and an ally of Caro Quintero. The report does not specify a date on which this occurred.

Harrison testified at the Camarena murder trial that he lived at Fonseca's house for several months in 1983 and 1984 when he was installing radio systems for the drug lord. He also has told the DEA that on several occasions he served as a guard on Fonseca's drug convoys, "using his Gobernacion {Mexico's Interior Ministry} credentials."

The DEA report, which was completed in February, does not state whether CIA officials knew who owned the ranch where the Guatemalans were being trained, why Guatemalans were being trained or if marijuana was being grown there.

Asked about the allegations, CIA spokesman Mark Mansfield said, "The CIA does not engage in drug-running activities."

The DEA reports became available late Tuesday night after U.S. District Judge Edward Rafeedie ordered federal prosecutors to turn them over to defense lawyers in the Camarena murder trial, which is nearing the end of its seventh week.

Caro Quintero, Fonseca and former DFS commander Sergio Espino Verdin are serving prison terms in Mexico after being convicted on charges stemming out of the kidnapping and murder of Camarena.
