Pseudonym: Purcell, Susan
Egerter describes CI/SIG as "Counter Intelligence, Special Intelligence Group".
1959-1963: "Interview with Susan Purcell. Date: March 31, 1978. Interviewed by Dan Hardway and Betsy Wolf. "...Ms. Purcell explained that her assignment with the CIA in 1959 was in CI-SIG. She believes that "SIG" stands for Soviet Intelligence Group, although she was not positive that the "S" stood for Soviet. She later explained that it might have been Special Intelligence Group. The purpose of the staff was to operate as a liaison between the CI Staff and the Office of Security, primarily as an informational transfer point. Her supervisor was Birch O'Neal who served as Chief of the CI/SIG division. She described the office as being 'a most secure office' meaning that it was a vaulted area. This was due to the fact that the office held several files which were considered to be sensitive...she cited as an example the case of Jack Sobel (phonetic) who was operating as a double agent. The CIA was particularly interested in him because he had said that his brother was a double agent who had had five agents within the OSS. Therefore, it was necessary for the agency to track down those persons...her office dealt mainly with cases that involved espionage and infiltration of the Agency...
1959-1963: She said that SIG was known as 'the office that spied on spies'...Purcell stated that upon opening Oswald's 201 file, she was responsible for compiling the file. Any documents that she received would have been added to the file. She recalled reviewing documents on Oswald's Cuban activities at some point. She mentioned that she also opened two other general files on defectors. One of the files concerned defectors from the US to Soviet Bloc countries while the other file concerned defectors from Soviet Bloc countries to the U.S. He showed Ms. Purcell the 10/31/59 State Department telegram concerning Oswald's defection and his offer to give the Soviets information obtained during his military service. This document is a portion of CD 294, a compilation of documents concerning Oswald in the CIA's possession prior to the assassination. She recognized the document and was familiar with the information contained therein. She first stated that a name trace should have elicited this document. That document is page 89 of CD 294, and can be viewed here: https://www.maryferrell.org/showDoc.html?docId=10695&relPageId=89&search=%22October_31%22
5/26/61 routing sheet from SR/CI/P/dl (probably David Lynch or Dottie Lynch) to C/SR/CI/P opened on State Dept Foreign Despatch #806. Note from C/SR/CI/P, Subject - Oswald, Lee Harvey: "FYI. WP (Will Potocki) had originally asked me to pull together all refs on this man. Since then it has been determined that Betty Eggeter is determined and either holds 201-289248 or has it restricted to her." pp. 13-16: Egerter signs off as "CI/SIG/Eggeter" on routing slip stemming from LHO's opposition to undesirable discharge issued by Marines for his alleged "renunciation of citizenship".

Bright - at 10/3/62 - several months after Oswald's return to Texas in June 1962, there is a note from "DL" - probably David Lynch or Dottle Lynch - at DBA 20883 stating "(Illegible) Betty Eggeter CI/SIG has full file." (This file was initially opened on 8/30/62 - at the time of John Fain's FBI memo on Oswald.)
