Summary  
The documents detail investigations into James Earl Ray’s alleged involvement in the assassination of Dr. Martin Luther King Jr., including forensic evidence, interrogations, and prison records. A sheriff’s report from DeWitt County, Iowa (October 9, 1962) notes Carl Raymond Osborne and Allan Walter Alexander were interrogated regarding their ties to Robert Dale Porter (alias Bob Cline), George Worthington, and Ray. Osborne claimed participation in a plot to kill Dr. King, referencing an escape from Jefferson City Penitentiary and a car purchased in Marshalltown, Iowa. The report states Porter and Ray were arrested in Memphis, Tennessee, with Osborne providing a check signed by Walter Alexander. An FBI memorandum (October 16, 1968) details George Bonebrake’s identification of James Earl Ray via latent fingerprints found at the crime scene, linking him to Memphis. Bonebrake testified that prints matched Ray, who had been arrested in London and previously incarcerated in Missouri. The document also references a fingerprint analysis seminar conducted by Bonebrake for law enforcement agencies. Missouri State Penitentiary records (March 17, 1960 – November 23, 1967) outline Ray’s incarceration, cell assignments, and escape, with Donald Lee Kitchell noted as a former inmate connected to his prison history. Additional FBI records from 1960–1968 reference Robert Dale Porter’s arrest history, including charges of “uttering false checks” and internal memos evaluating information from Carl Raymond Osborne. Some entries contain redacted text marked with locators <loc_588> and <loc_590>. Porter was no longer wanted by the FBI in 1960, and case numbers such as 4590 432 are referenced alongside internal communications involving Kansas City and Memphis SAC divisions.
