A new book delves into those mysteries, including pay phone calls made by King assassin James Earl Ray, some of which may link the assassination to the Ku Klux Klan:
So far the authors haven't been able to track down two phone calls made to Mississippi. Each number was unlisted.
One was to south Jackson: (601) 372-3537.
The other was to Laurel: (601) 428-8829.
In those days, Laurel was the headquarters of the White Knights of the Ku Klux Klan in Mississippi and the home of Imperial Wizard Sam Bowers. Bowers' business, Sambo Amusement, had an unlisted number then.
FBI records mention the White Knights' offer of a $100,000 bounty to kill King — a bounty that Ray may have believed he would get if he killed King.
