Okay, I'm tossing my two cents in...
I, for one, am relieved the dad has made some kind of public statement, if only in his own defense. The silence was really taking on a personality of it's own and distracting from Dylan.
Perhaps that is why the mom made a public semi-accusation? If they were married for so long (20 years?), I'm sure she knows how to push his buttons...hell, maybe she said that to protect him from the media's sideways glances (far fetched and a little twisted, I know) & provoke a public response to break the silence.
Maybe Dad has a very, VERY quiet & unemotional personality (like my husband...YAY ME!) & is adamant about not showing emotion, especially publicly, fearing if he did, he would be attacked in the media for not being emotional enough.
Just playing devil's advocate...with a little insight to personalities I find "odd", courtesy of my beloved hubby.
Now, what really concerns me, is that with all this drama, if Dylan was abducted, he could be ANYWHERE by now. Dad's not going anywhere & I'm willing to trust LE to state a POI, when the time comes. Right now, Dylan MUST be found...&, IMO, exhausting all avenues to find him alive (abduction) should be taken first.
