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." Just hours earlier, based on evidence uncovered by the filmmakers, Durst had been arrested in a hotel lobby in New Orleans. 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.
