I've recently seen clips of interviews of two sets of parents, both of them so fascinating because of their insistence in believing their child-killing children.
Of course, one is Dr. Phil's interview of Casey Anthony's parents, which have been replayed in parts by Drew and Mike on WRIF, 101-fm.
But even worse, or more outrageously entertaining, are the parents of John Skelton, the man who is being sentenced today for unlawful imprisonment, the charge he pleaded to in exchange for prosecutors dropping a charge of parental kidnapping of his sons. The three boys are presumed dead, having gone missing a year ago.
My, what parents will go through to believe their child is not a monster. Great interview by Seven's Tom Wait, especially getting their explanation of why Skelton has searched for "neck breaking" on the internet (2 min. in):
