I am going to refuse to see KC as the victim here. There is a victim but it's not KC. There are plenty of unfortunate cases where a child dies accidentally from some kind of parental neglect. Normally, the parent would do everything in their power to save the child, they would bring the event to light, call authorities, call emergency response, get loved ones involved, show grief, show concern, be remorseful, feel guilty, etc.
Their thoughts would go from saving themselves, to saving the child if at all possible. Failing the child being saved from the accidental circumstance, it is laid to rest with dignity and the parent willingly suffers the consequences of their negilgence.
But KC has done None of that. Her attention never went away from herself and to the "accident" victim. She has been secretive, dishonest, gone underground, was never going to report it, did not ask for support or help, and evidence suggests she may even have planned it. And now we find the victim here wrapped in a bag and thrown in a garbage heap, which is not indicative of an accident victim. LE knows how to tell one parent from the other and gave KC every opportunity to come clean and admit it was a terrible accident. She did not. LE has profiles of parents who caused a terrible accident by neglect or a mistake, and parents who commit these terrible crimes on their children. LE has concluded, after considerable analysis of the facts and evidence, that KC is most likely part of the latter category.
