The arrest of Mark Redwine for the 2013 murder of his 13-year-old son Dylan has been four years coming, but it is no surprise to the boy’s mother. Elaine Hall has fought hard to convince investigators that her ex-husband killed her son and hid his bodies on a Colorado mountain.

Dylan didn’t want to board the plane that would take him to his father’s for a Thanksgiving visit, but it was ordered by the judge overseeing the couple’s child custody battle, Hall tells Nancy Grace in this “Crime Stories” episode.

“Dylan and his dad had just grown apart,” Hall says. “Mark never really exercised his visitation rights. And so you know he couldn’t see Dylan that often and you know, quite honestly, I don’t think that Mark new Dylan anymore.”

A day after her son left his mother’s home, his father called Hall to say Dylan was missing. Hall’s unbelievable nightmare was just beginning.
