In this harrowing episode of Secrets of the Underworld, Neil sits down with Colby Ryan, a man whose life was shattered by one of the most disturbing family crimes in modern American history.

From a childhood marked by constant moves and doomsday ideology. To the shocking murder of his stepfather Charles Vallow, to the disappearance and tragic deaths of his siblings Tylee Ryan and J.J. Vallow — Colby shares what it was like to watch his family unravel from the inside.
