Someone Knows Something

David’s TV documentary about Christine comes out in the spring of 2012, publicly revealing details of the case for the first time along with key interviews including a face-to-face with Anthony Ringel. In the aftermath, police launch an undercover operation on Ringel. David and Mary Ann's work proves key and Ringel is re-arrested. Will Ringel finally go to trial and Mary Ann learn the truth?

The case against Anthony Ringel falls apart and he is freed. And Mary Ann says she's been kept in the dark. How did it happen, and is Anthony Ringel even guilty of what he says?

A decade after her disappearance, a previously uninvestigated local man comes forward at a family gathering and confesses to killing Christine Harron. Chrissy's mother Mary Ann is told that the case is a "slam dunk". And the outcome of an upcoming trial could mean she will finally learn the truth. But this is just the beginning.
