They're the lost police radio tapes from the assassination of Dr. Martin Luther King.
Stunned witnesses point at the window where the assassin fired from. While the famed civil rights leader lay dying on the balcony of the Lorraine motel in Memphis.
A voice on the recordings said, "We have information that King has been shot at the Lorraine. He has been shot."
The tapes continue with, "All TAC units on the call, you are to form a ring around the Lorraine motel."
"You feel like you're watching the events of the King assassination for the first time," said filmmaker Tom Jennings.
