I just watched the press interview of the father. One sentence spoke volumes to me. It was at the end. He was asked what he'd say to his boy if he could. He responded, "I'd say, 'Maddox, M-A-D-D-O-X, I love you, buddy.'"
He said it in a way that made me feel that he'd said this exact sentence many, many times before, spelling out the name for the child to learn. A parent who makes concerted efforts and wants to teach a challenged child how to spell his name is not likely the kind of parent that would harm that child. I admit, when I first heard of the Maddox Ritch story, I immediately thought of Ara (Pique) Andressian. In that case, the father is now serving time. After seeing the interview of Ian Ritch, I no longer get that vibe.
I sure hope I'm right.
