I am so sorry about your son. I know kids that young can't comprehend death but the degree of violence inflicted upon Michelle produced a lot of blood and the blood would have left an impression on Cassidy if she had witnessed it, imo. I think she was sound asleep when the attack happened and Michelle was dead by the time CY saw her. Which then begs the question as to where CY was in all those hours that she remained clean.
Here's a theory. There was one attacker. Attacker goes overboard and kills her in a drunk rage. Attacker freaks, leaves the scene, calls a friend or two. Friend or two come back, help clean the scene, and take CY and clean her at a different location. They can't keep CY, so they bring her back at a later hour.
Makes more sense than the prosecution's theory.
