What Happened to the McStays?

In a quiet suburb of San Diego County, a family of four seemingly vanishes into thin air. When investigators search their home, they find the family’s two beloved dogs unattended outside, rotting food left around the house and clothes strewn across the floor.

Did the McStays leave of their own accord, or did something far more sinister happen? A six-part series from 20/20 and ABC Audio, hosted by Ashan Singh.
