I think jnTexas you are right, and that KC is not so special. I believe she murdered her child or at the very least is culpable in her death.
Unfortunately, Mothers murder their children all the time. This woman states that she murdered her daughter because a man told her she had to make a choice. Even if Mr. Macumber says he made that statement, I see it as the Mother putting the onus of the murder on someone other than herself by a kind of "he made me do it" mentality. Susan Smith was dumped by a man before she murdered her boys, I think it was an excuse for her.
I come to these threads and to a few other threads and not so much to the KC threads because I have come to realize that KC is mundane. She is the run of the mill Mother who killed her child type. She is not special in any way shape or form.
My heart aches for the Karissa's and the other children of the world who's horrifying deaths at the hands of their Mothers who don't get the media play that others do. Karissa's face was sweet and her smile was beautiful. May she rest in peace.
