However one see this case, IMO, it is difficult for me to pretend that MR is your basic non-custodial dad. I happen to believe Azgrandma as to what she has shared about him. He has been charged with "menacing" in the past, which even if eventually dismissed, is alarming to me. I have never known anyone charged with that, sounds scary. His older children seem to have chosen not to have contact with him. His most recent ex, ER, has voiced fears as to how he might react if Dylan made him mad.
So to me, all of that has to at least be taken into consideration, now that Dylan is seemingly gone without a trace. MR is extremely, astonishingly unlucky in that his child vanishes under his care and during such a tight, non-threatening timeframe, in such a remote area. Or there is more to it.
