How do I know C.W. murdered all 3? Mostly, I would say, it was his demeanor in first few days following the murders. If CW had suffered the shock of discovering that Shanann had strangled and murdered Bella and CeCe, he would have suffered a huge, devastating loss when the loves of his life were ripped away from him, as opposed to a feeling of accomplishment he would have felt, after carrying out a his well thought out plan to free himself from his ball and chain family that kept him from doing what he really wanted to be doing. I’ve seen many people in the first stages of grief. They can’t control their emotions. CW was not in grief. People experiencing grief are in shock, tears, uncontrollable outbursts of emotion, sorrow. CW showed none of that. He was in complete control of his emotions. He was concentrating on executing the final stages of his plan to annihilate his family.
