At the end of the original series, "The Jinx: The Life and Deaths of Robert Durst," viewers around the world were stunned to hear Robert Durst utter the words "Killed them all, of course."

The filmmakers continued their investigation for the next eight years, uncovering hidden material, Durst's prison calls, and interviews with people who had never before come forward.
