It's pretty clear that this individual struggles w/misplaced anger issues, and, unfortunately, cannot resist using this horrific situation to continue to lash out @ his ex-spouse.
The most striking example of this is the comment about how Dylan gravitates to him moreso than his mother, even though she is the child's primary caregiver.
Sorry guys, but this individual is a problem. Probably always has been and always will be. And, the fact that every single circumstance can 'possibly, maybe, could be' explained away - even if not practical nor reasonable - does not change that fact.
No person is perfect, and, if folks were to pick our actions apart in the minutest of detail, no matter who we are, he/she will find credibility issues. But, there comes a point when an outside observer - one who has no personal investment in the guilt or the innocence of the individual in question - comes to a conclusion based upon reasonability and practicality.
Someone (in law enforcement, I suppose) needs to go after Mr. Redwine hard and get the answers which are needed to find this child.
