When it premiered on HBO a decade ago, the true crime docuseries “The Jinx: The Life and Deaths of Robert Durst” stood out mainly because of Durst’s willingness to appear on camera. The wealthy New York real estate heir was suspected of killing three people: His first wife Kathleen McCormack in 1982; his close friend Susan Berman in 2000; and an elderly Texas neighbor Morris Black in 2001.
