This is a one-page FBI internal office memorandum dated April 17, 1958, originating from the FBI Detroit field office. Special Agent Robert Ross Reynolds authored the memo to the Special Agent in Charge (SAC), Detroit, reporting a 4:08 A.M. telephone call from a Detroit resident named Weaver, residing at 15801 Decosta, Detroit. Weaver reported observing a circular object with a crystal-type dome reflecting lights, traveling in a northerly direction from the southwest, crossing the city approximately three blocks south of Six Mile Road at Lamphere Street. The witness was 23, the son of a Detroit police officer, and had Civil Air Patrol experience, though he self-reported limited aircraft identification knowledge.
The memo is notable primarily as a procedural record illustrating standard FBI handling of UFO reports during this period: the bureau received the account, documented the witness's credibility markers, and recommended forwarding the information to Air Force authorities. The witness's name is partially visible despite nominal redaction. No Air Force follow-up documentation is included, and no additional investigative action appears to have been taken beyond this single-page referral memo.
