Played by Robert Durst
The oldest son of New York real estate entrepreneur, Seymour Durst, Robert Durst grew up in Scarsdale, New York. He married Kathleen McCormack in 1973, and after she went missing in 1982, Durst has been considered a suspect. Further suspicion was raised with the unsolved 2000 killing of his confidante, Susan Berman, thought to be a key witness in the investigation into Kathie's disappearance, as well as the subsequent killing and dismemberment of a neighbor in Galveston, Texas. Durst, who has consistently maintained his innocence, was arrested on March 14th, 2015.
