</s>2" OCT 1958 Mr. Richard Nixon National Headquarters- Wallard Hotel E-FORFORTER PERSONAL 2025 RELEASE UNDER E.D. 14176

Summary:  
The document details FBI investigations into a letter addressed to Richard Nixon and Hubert Humphrey at the Willard Hotel in Washington, D.C., postmarked October 22, 1968. The letter, potentially linked to Sharif B. Sirhan, was analyzed for handwriting comparisons. The FBI Laboratory found the signature on QC35 too indistinct to match known samples of Sharif Sirhan’s handwriting. Specimens from Pasadena Police Department and welfare fund receipts were examined but yielded inconclusive results. A tape recording made by Stus Pruszynski on June 5, 1968, was reviewed for intelligibility; the original recording had interference, prompting a dubbing attempt. The FBI sent copies of the enhanced tape to Los Angeles for review, though no pertinent information was found. Multiple lab reports from November 1968 and June 1969 document these efforts, with notes on administrative procedures and specimen retention.
