The second episode of the HBO documentary series , titled " Poor Little Rich Boy ," originally aired on February 15, 2015. It focuses on the early life of real estate heir Robert Durst and the mysterious 1982 disappearance of his first wife, Kathie McCormack Durst. Episode Summary

The episode highlights that the only person speaking in Durst's defense is his high-priced attorney, as no former friends or associates appear on camera to support him.

Eschewing his father’s real estate empire, Durst moved to Vermont to open a health-food store with Kathie. He describes their early relationship as a "Cinderella" story, though he eventually felt pressured to join the family business.

Durst admits to filmmaker Andrew Jarecki that he lied to the police during the initial investigation, claiming he did so because it was "more convenient". Key Figures Featured

The episode spans two primary timelines—childhood and 1982—to build a profile of Durst as a "singular, compelling, and occasionally terrifying individual".

Durst claims he drove Kathie to a train station and that she traveled alone to their Manhattan apartment. However, investigators note that no one on the train remembered seeing her, and it is implied Durst may have used disguises to impersonate her and create a false trail.
