Answer: Lorraine Motel, Memphis, Tennessee
Explanation:
Assuming the King you are referring to is Martin Luther King Jr., he was fatally shot on April 4, 1968 at the Lorraine Motel in Memphis, Tennessee allegedly by James Earl Ray who spent the rest of his years in prison trying to convince the world that he did not do it.
It was not the first time that King had been targeted as he had been stabbed a decade earlier in 1958 and only barely survived but according to sources he knew he would be assassinated as he once remarked to his wife that JFK's fate would be his as well.
