Robert Alan Durst was a convicted murderer, a suspected serial killer, and an American real estate heir. The eldest son of New York City real estate magnate Seymour Durst, he garnered attention as a suspect in the unsolved 1982 disappearance of his first wife, Kathleen McCormack; the 2000 murder of his longtime friend, Susan Berman; and the 2001 killing of neighbor Morris Black. Acquitted of murdering Black in 2003, Durst did not face further legal action until his participation in the 2015 documentary miniseries The Jinx led to him being charged with Berman's murder. Durst was convicted in 2021 and sentenced to life imprisonment without parole. He was also charged with McCormack's murder shortly after his sentencing, but died in 2022 before a trial could begin.
