Disclaimer: I've been trying to read & read to get caught up on this case. I've been following it, albeit not as closely as the rest of you.
A few things I've observed and will opine: I listened to the 911 call on my headphones. Not state of the art, by any means, but near the beginning, where Cassidy is asking for the washcloth, I heard, "mommy got...mommy got boo boos." And I listened to it again for the Daddy did it. I didn't hear it then and almost gave up. Then, near the very end of the call, when the 911 operator is calling for the police, I hear clearly, "daddy did it." In my opinion, at that time, a 2 year old hasn't had enough coaching from anyone to be led into saying that daddy did it. Also, I agree with many posters here, that she probably just thought mommy had boo boos and was asleep. Death or the finality of it, had not come into that baby girl's head. Her only reality was that her mommy wasn't waking up.
I would also take a guess that whatever blood that was on Cassidy, at the point in which Meredith came in, was fairly dried. Which would lead Meredith to believe that Cassidy wasn't hurt. Therefor, she didn't need to run, screaming from the house with Cassidy.
In regards to her not being able to move Michelle, if I were holding the phone with my chin on my shoulder, depending on the angle that Michelle would've fallen, (perhaps her knee(s) were under her) I would think I would have a hard time moving someone. Besides, iirc, rigor had begun to settle in.
I also believe that Meredith was trying to keep herself calm for Cassidy. I have done that, myself, in certain cases, (not like this one!) but I imagine that's where Meredith was coming from. Then, break down into a crying ball when the urgency is over.
When, in the 911 call, she says that she's her "only sister", I think that's where it hits her that she's all Michelle has & vice versa. I just cannot imagine finding my sister this way.
I don't believe one iota that Meredith had anything to do with this.
I really hope that Raleigh/Durham police start making some arrests when it comes to pregnant mothers being murdered in their very own homes.
All of the above are certainly my opinions only.
