1. This memorandum is in response to the request

in paragraph 4 of Reference A.

CCS files contain

information on five of the ll individuals identified

in Reference B as follows:

Alias Dan Carswell (True Name David L.

Christ) -- Approximately 30 documents, virtually

all of which concern the establishment, maintenance

and use of cover for Subject during his Agency

career as a Staff Employee from 1956-70.

b. Louis Posada -- CCS maintains a covert tax

file on Subject containing 58 documents covering

his employment as an Independent Contractor from

1968-75.

Information in this file may be released

only in accordance with the provisions of Section

6103 of the Internal Revenue Code.

In the opinion

of CCS, the time frame of these documents would make

them irrelevant to the investigation being conducted

by the HCSA Staff.

Cesario Diosdado -- Approximately 25 documents

on Subject, a Bureau of Customs official who assisted

CIA frOm 1961-68 on a reimbursable basis. Virtually

all of the documents concern arrangements made between

CIA and Customs for the use of Subject.

The Commissioner

of Customs should be contacted prior to release of

information in this file.

Davia Attlee Phillips -- 125-150 documents,

virtually all of which concern the establishment,

maintenance and use of cover for Subject during his

Agency career as a Staff Employee from 1953-75.

inquiry.
