In 1968, King was planning a national occupation of Washington, D.C., to be called the Poor People's Campaign, when he was assassinated on April 4 in Memphis, Tennessee. His death was followed by riots in many U.S. cities. Allegations that James Earl Ray, the man convicted of killing King, had been framed or acted in concert with government agents persisted for decades after the shooting.
