SECRET
11 December 1995
MEMORANDUM FOR : Chief,' Historical Review Group
FROM: Fredrick C. Wickham, Jr _
DO, Focal Point for ARRB
SUBJECT : DO Position on Identification of ERTHYROID/ 3
1 The DO strongly opposes the release the ARRB of the
phrase "a good KUBARK asset" that was previously withheld in
Attachment_ The CIA asked the Nicaraguan Service to send
ERTHYROID/ 3 to Mexico City to help in the interrogation of
Alvarado Because this was during the Samoza regime, we have
admitted that we had a liaison relationship with the Nicaraguans
and we also have released the cryptonym ERTHYROID_ ERTHYROID/3
became well known to the Mexicans as the Nicaraguan interrogator
and, of course, was known his own 'service The phrase good
KUBARK asset, "i however, identifies him as a unilateral source of
the Managua Station unbeknownst to the Nicaraguan and Mexican
Services
2 The DO often recruits officers , such as ERTHYROID/3 , who
are members of intelligence and police services with which it has
a liaison relationship _ These assets provide us valuable
information without the knowledge 'of the service and in many
cases provide information about the service itself and its
activities To reveal ERTHYROID/3' s identity and his special
relationship with the CIA would not only personally endanger
ERTHYROID/3 but could cast suspicion on other recruited officers
of other liaison services and compel them to reevaluate their
unilateral relationships with the CIA
