06/30/71: Dispatch from Withheld to Chief, European Division (Info: Chief, SR Division): Subject: GROOVY REDLEG AESLITHER Austrian Newspaper Article on Victor Louis: "1. Transmitted herewith is an article on Victor Louis which appeared on the 30 June 1971 issue of Die Presse. We would like to take credit for it, but it actually appeared spontaneously (at least so far as the Station is concerned), the wake of the recent reports of Louis's travel to Israel. 2. Louis will presumably continue to be eminently newsworthy, and we would like to remind Headquarters that we hold information on his frequent visits to Vienna in the past two years. Part of this information was obtained from (REDACTION) and part of it from GRENGULF (Austrian State Police), as a result of a lead provided (REDACTION). If Headquarters is interested and will authorize release of this information, we are sure that we can get good play on a story keyed to the local angle, working through GRCAMARA (Otto Schulmeister). (REDACTION)." - - - For crypts GRENGULF and GRCAMARA see page 30 of this document: https://www.archives.gov/files/iwg/declassified-records/rg-263-cia-records/second-release-lexicon.pdf

SUMMARY: CASUSTAIN/15 (Inge Marie Gehrich), who was orginally contacted on the basis of a lead to her close friend, Iden 1 - supplied by Fletcher M. Knight (Richard Helms), has developed access to a local PCS Soviet (AENOG) and supplied useful assessment data on him. Her observation of AENOG's relationship to his students strongly suggests that AENOG is a RIS cooptee. Redirection will be necessary after AENOG departs Hamburg in June 1974. Plans are for reexamination of Iden 1's expressed willingness to cooperate and of CASUSTAIN/15's circle of press and émigré contacts..." - - - Page 4: "IDENTITY 1 - Gunter M.
