I would not be surprised if either of these two scenarios played out. It's a very long story and I'm not going to tell it, but, I have my reasons for believing Dad, when he said that they were supposed to closely watch the eldest around other children. I took that to mean siblings, as well. I don't think that mom, or EK, were watching them, at all, and were likely making matters worse in a home, filled with EK and mom fighting, and the like. I'm not hating on a child, I'm just looking at it from stark reality. I will say, that a family I know, after years of therapy, had to place their child, a little younger than the one in this case, into another family member's home for awhile (no small children). All we know about the child's background, is what Dad has told us, and if we are to believe what he's told us, it's not good, even if the child had nothing to do with this particular incident, there is a reason they were told to watch him around other kids. It's there. Dad told us why. If I read it right.
