The documents detail FBI investigations into long-distance telephone calls made from public telephones on U.S. highways (Interstate 10 and Highway 90) between December 15-17, 1967, with connections to Memphis, Texas, Oklahoma City, San Antonio, and other locations. The focus is on tracking individuals associated with James Earl Ray, a suspect in the assassination of Martin Luther King Jr., though direct links are not explicitly stated. Key leads include William Carl Henderson (Jackson, Miss.) reporting interactions with Sylvia Snowden, Glenda Wilkinson, and an individual described as "JIMMY (LADY)" resembling Ray. The FBI sought to locate and interview Snowden, Wilkinson, and others for background checks on their associations with Ray. Telephone records were verified, and some individuals were marked as "ARMED AND DANGEROUS." Investigations also involved calls from San Antonio to Oklahoma City, linked to Robert Parker and Richard Hardard, with no confirmed ties to MLK's assassination. Additional records include calls placed by James Earl Ray between Los Angeles and New Orleans, toll booth checks, and interviews with Tommy Lee Webb, a Marine Corps sergeant in Dallas, who reported no contact with Ray. The FBI also investigated telephone numbers linked to Prince Dixon (Los Angeles), Felix Robinson, and Robert B. Carpenter, while administrative procedures and redactions for sensitive information were noted.
