Before he became one of America's most infamous suspects, Robert Durst was the eccentric son of a New York real estate dynasty. In this first installment of our three-part series, we explore the 1982 disappearance of his wife Kathie Durst, the 2000 execution-style murder of his best friend Susan Berman, and Robert's flight to Galveston, Texas, where he lived disguised as a mute woman.

What connects these deaths? And who is the dismembered neighbor whose body parts washed up in Galveston Bay?
