104-10400-10162: CALDERON, LUISA
11/22/63: Handwritten note provided, with analysis by Rex Bradford: "...(A) taped call, one which caused the HSCA much consternation, involved Cuban Embassy employee Luisa Calderon. Volume XI of the HSCA's Report, careful to avoid disclosing sources and methods, laid out the issue: A reliable source reported that on 22 November 1963, several hours after the assassination of President John F. Kennedy, Luisa Calderon Carralero, a Cuban employee of the Cuban Embassy in Mexico City, and believed to be a member of the Cuban Directorate General of Intelligence (DGI), discussed news of the assassination with an acquaintance. Initially, when asked if she had heard the latest news, Calderon replied, in what appeared to be a joking manner, "Yes, of course, I knew almost before Kennedy." [HSCA Report, Appendix XI, p. 494] The "reliable source" is again a telephone tap, which captured a conversation at 5:30 PM local time, several hours after the assassination. A loose "transcript" of the conversation starts this way: HF asks LUISA if she has heard the latest news and LUISA, in a joking tone says, "Yes, of course, I knew almost before Kennedy." HF smiles and comments that it is very bad; …. There are a few oddities here. How one ascertains that a person is "smiling" in a telephone conversation is one. Also, this conversation was accompanied by a handwritten note which includes: "22 Nov Lienvoy Luisa Calderon and man outside." "Man outside" is typical CIA-speak for a man on an outside telephone line (and LIENVOY is the teltap operation). But the "transcript" notes that the other person is HF, presumably Hispanic Female. The handwritten note also says that "cc original and transcript sent to Galbond via Kingman. Nothing to Buro yet," interestingly keeping the FBI in the dark for the moment. [Handwritten note and transcript at RIF #104-10400-10162, p. 2] For more - see https://www.history-matters.com/essays/frameup/MoreMexicoMysteries/MoreMexicoMysteries_3.htm
11/27/63 memo: "Sending photostatic copy of ten page statement by Silvia Duran obtained from Echevarria/LITEMPO-8 by hand of Roger T. Kingman in envelope addressed to Galbond/J.C. King true name. Kingman arriving at Dulles Airport at 0800 hours 28 November. He will be met by his wife, hopes she will tell him what to do with envelope. Sorry no time to translate statement..." Kingman had both the Duran and the Calderon documents with him.
11/28/63: Kingman believed the evaluation of Oswald had been seriously warped due to misinformation provided about Oswald supposedly depositing 5000 dollars in a bank.
104-10195-10158: CABLE: FOLLOWING IS PERTINENT EXCERPT FROM PAGE 364 WARREN COMMISSION REPORT
9/28/64: Kingman carried a copy of the just-published Warren Report, presumably back to Mexico. Handwritten marginalia from Chief of Station Win Scott states: "Note: I suppose we relax. Let happen whatever happens!"
104-10187-10018: ADD/P APPROVAL OF RENEWAL
12/18/64: C/WH/PO/K Horton signs off on LIEMPTY routing slip.
2/11/65 memo reveals some background on Luisa Calderon and why she was recalled to Cuba in 1963 - the Cuban government feared she had been doubled by the Americans! Proenza was recalled about that time because of the CIA's AMROD project to cause dissension within the Castro regime - Calderon may have been caught up in that as well.
10/25/68 John R. Horton is listed as AC/WHD.
ARRB Deposition of Anne Goodpasture, Part 1
April 1971: Horton was in Mexico when Scott died. Goodpasture thinks he was chief of station during that time. Also see 1993.08.09.16:53:05:030039 - page 3 -Kingman went thru the docs in Scott's study with his wife. Also see 104-10129-10097, RYBAT JMSPUR cable from Mexico City to Director, directed to Lusby and Ashmead/James Angleton: Tapes included material on the Rettie case, "lesbians" (note: probably Theresa Proenza and the AMROD matter), Black Panthers Huey Newton and Eldridge Cleaver (note: presently involved in an international split within the party).

Also 104-10067-10291: March 1978 revelations by FNU Bach to NBC resulted in mention of Roger Kingman as Chief of Station in Mexico City.

1993.08.09.16:53:05:030039: MEMO ON MANUSCRIPT OF FORMER COS, MEXICO CITY
10/6/78 interview of John Horton by Scott Breckenridge: Horton believed that Win Scott had "gone to seed" and started making up stories about Oswald being photographed coming in and out of the Soviet embassy. "He did not know whether this was a result of drinking or other factors. He said that Scott was like an old soldier, who told stories of his 'victories in battles that he never fought.'"
