Today (January 19) is Martin Luther King Day, a national holiday.
King was an American civil rights leader who was assassinated 47 years ago on April 4, 1968, at the age of 39. James Earl Ray was blamed for the murder. Initially, Ray admitted the murder, apparently under advice from his attorney in order to avoid the death penalty, but Ray soon withdrew his confession and unsuccessfully sought a jury trail.
Documents of the official investigation remain secret until the year 2027.
