This was on page 15 of 41 on Zodiac 2 PDF and dated November 6th 1969.
The follow up page 16 of 41 was regarding the testing of latent fingerprints for comparison to known fingerprints held on file, dated November 7th 1969, in regard to the 11/6/69 teletype and it was important to see what follow up was conducted regarding this sighting. The FBI file below indicates that the sighting of the 8 year old was followed up immediately and Xenophon L Anthony's fingerprints bore no correlation to the fingerprints on file.
I will upload the file that I received today from the FBI in due course, but for now here are the actual redacted areas filled in with the relevant names. FILES NOW UPLOADED.
