We also don't know that he didn't also want to kill Cassidy, as harsh as that may sound. Maybe he just couldn't do it either from looking at her while sleeping, or maybe she woke up and he really couldn't do it then. I think she saw Daddy only because I heard "daddy beeding" on that 911 tape. Which to me meant "daddy bleeding". IMHO Wonder if Cassidy had any insurance value?
If this was as brutal as it sounds, Cassidy could have gotten out of bed to see what was going on. Especially if she wasn't in a crib. Was she potty-trained? Maybe she got up to go potty.
Like raisincharlie said, Cassidy had no concept her mommy was dead. Just the fact that she wanted to get a washcloth and presumably clean up her mommy shows that. Again, my opinion because others have said they didn't hear Cassidy ask for a washcloth.
For what it's worth, I think JY has a heart like the Grinch and Cassidy could have been the 2nd victim, but something stopped him.
Oh, good morning everyone!
