Who Killed Martin Luther King?

At 6.01pm on 4 April 1968, Dr Martin Luther King was shot dead by a sniper in Memphis, Tennessee. Who fired that shot and why? For more than 20 years, the man convicted of King's murder, James Earl Ray, has protested his innocence. He says he was framed. Now Inside Story's dramatic new investigation closely examines the evidence and seriously questions whether Ray actually pulled the trigger.
After an extensive inquiry in America, the film tracks down key witnesses, who provide startling new allegations about the conspiracy to kill Dr King.
