Robert Alan Durst is an American real estate heir and suspected serial killer, the son of New York City businessman Seymour Durst and the elder brother of Douglas Durst, head of the Durst Organization. He is suspected of having murdered three people: Kathleen McCormack Durst, his first wife, who disappeared in New York in 1982; Susan Berman, his longtime friend, who was killed in Los Angeles in 2000; and his neighbor, Morris Black, who was killed in Texas in 2001. Durst was the subject of a multi-state manhunt after Black's body parts were found floating in Galveston Bay. Although he admitted dismembering Black, he was acquitted of murdering Black on the grounds of self-defense.
