Summary  
The documents detail FBI laboratory analyses of handwriting, fingerprints, and typewriter impressions related to investigations into potential threats against Martin Luther King Jr. (MLK) and the assassination investigation. Key items examined include handwritten letters, typewritten materials, financial documents, hotel registration records, and transportation receipts. The FBI compared these specimens to known handwriting samples of James Earl Ray, the accused in MLK’s assassination, as well as other individuals like Carl Ray, Eric S. Galt, Herman J. Schumacher, and Robert P. Anderson. Analysis focused on identifying connections between suspects, tracing movements via hotel records, and verifying signatures on financial instruments. Some documents were retained for further analysis, while others were returned to field offices. The FBI also sought assistance from local authorities to trace the origin of letters and envelopes, including one postmarked from Pelce Island, Ontario, Canada, which contained an anonymous note referencing MLK’s assassination.
