12/3/63 cable MEXI-7229 from Mexico City to Director ref DIR 86563: "(Chief of Station) spoke with Lic. Luis Echevarria/LITEMPO-8, acting minister of Gobernacion, at 1930 hours Mexico City time on 3 December. Echevarria said: He will order LITEMPO-4/Ferdinand Guterriez Barrios to hold Alvarado until (Chief of Station) is completed with 'some additional questioning'. In reply to (Chief of Station) request to 'sorrow' Alvarado, Echevarria said yes. Chief of Station told Echevarria that questioning would be done jointly with (FBI) and Chief of Station 'guaranteed' return of Alvarado to LITEMPO-4. Station has advised ERYTHROID-3/Capt. Franklin Anthony Wheelock Garcia of delay for two or three days in departure of Alvarado. ERYTHROID-3 will hope to remain in Mexico. Submit following plan for HQS approval: Will have Messrs. Clark Anderson and Joe Garcia of legal attache office pick up Alvarado from Gobernacion. Alvarado will be taken either to former ZRERASE safehouse or hotel suite. Advise. Clark Anderson and/or Joe Garcia will act as interpreters for Mr. Calvin Davis...will install microphones in apartment (safehouse) or hotel on 4 Dec to insure recording on Davis/Alvarado interview..." Chief of Station had suggested that Alvarado be polygraphed - "LCFLUTTERED".
Re early December 1963: Undated notes of unknown CIA officer - "Ambassador Mann was concerned that Alvarado had changed his story because he had been mentally and physically abused by the Mexicans...Mexico City Station reported that a PBSWING (embassy) investigation did not support Alvarado's claim he was threatened with hanging by the testicles. Alvarado met his case officer for the first time on December 2 and reverted to his original story, giving the above threat as reason for changing it. A cable was sent to Alexis Johnson by Mann recommending that (CIA) and FBI polygraph Alvarado in Managua. Headquarters agreed he should be polygraphed but not returned to Nicaragua until he was. The Mexicans were to turn over Alvarado to Mexico City Station, but they were not to be aware of the purpose for the release. Calvin Davis of KUSODA/Office of Security was to administer the polygraph and Clark Anderson was to interpret. After study with the legal attache it was decided that the interrogation should be held at an apartment used by KUCLUB/Office of Communications personnel...(Alvarado) took the polygraph and it indicated the story was false. Alvarado said he had the utmost confidence in the exam. Headquarters asked that the Mexican and Nicaraguan authorities not take punitive action that would cause Alvarado to resume his fabrication. Alvarado returned to Managua on December 8th...(p. 9): "...(the CIA) get a chance to possibly pin the assassination of JFK on (Castro's) regime and it seems they are trying to disprove Alvarado from the beginning. I have no explanation why this would be because it is so out of character."
