UNITED STATES GOVERNMENT Memorandum SECRET TO : Mr. D. J. Brennan, Jr, FROM : Mr. S. J. Papich SUBJECT: MANUEL PINEIRO IS - CUBA DATE: 10/10/63

We previously have been informed that the subject is a high-ranking official in the Cuban G-2 organization in Havana. On 10/8/63, Mrs. Anita Potocki, a CIA analyst who has been working on intercepted Cuban communications intelligence traffic advised the Liaison Agent that her Agency has come to the tentative conclu- sion that Pineiro is identical with Petronio, who has been men- tioned in messages made available to the Bureau and CIA. We have noted that messages sent to the unidentified Cuban Agent in Panama referred to as "Roberto" have been signed by "Petronio."

Mrs. Potocki gave the following explanation which led to CIA's deduction.

Messages emanating from Havana indicated that one of the recipients was probably located in a small town in Colombia near the Venezuelan Border. CIA developed a suspect and instituted coverage. Recently, this individual transmitted a letter to Havana which communication was intercepted by CIA.. The person had apparently violated instructions by including some sensitive data in the communication. Havana then transmitted a radio message castigating the Cuban Agent in Colombia. An examination of the the radio message and the intercepted communication sent by the Agent has led CIA to believe that "Petronio" is identical with Pineiro
