Summary:  
The documents detail FBI tracking of individuals associated with potential threats to Martin Luther King Jr. (MLK) following his assassination on April 4, 1968. Harold Hyman, brother of Clifford May, a former Nation of Islam officer linked to Malcolm X, is noted as having traveled to Memphis and Atlanta. Laurence Henry, a freelance photographer, departed Detroit via non-Philadelphia airports. John Bryant Jr., Marcellus Arrellus Andrews, and John Turner left cities like Newark, New York, and Wilmington, Delaware, via non-Philadelphia airports. The FBI monitored their movements, with photos of these individuals sent to Atlanta and Memphis. A March 1968 event in St. Louis, sponsored by the Mid-City Community Congress, is referenced as a memorial for MLK, involving planned routes through St. Louis neighborhoods and police coordination. Racial tensions and potential disturbances are noted, including window-breaking incidents during the march. The FBI emphasized handling information about MLK's assassination with sensitivity, using code names like "MURKEN" to avoid public disclosure of investigative details.
