So the last time Anna was seen alive (or at least moving) was between 9:30am and 10:00am by Moe?
As far as I can see, the last person who would have seen Anna alive would be Howard. It's obvious because he obviously instructed Brigitte "to watch over her". Taz was in a "secondary watch" location because Brigitte noticed something wrong "first" and called her in.
I wonder about that. Was HKS in the bed with her and was it actually HKS moving? Was she all covered up? Did he see her head move or what? Can we believe/trust Moe completely?
Perhaps, nobody actually saw her talking and ALIVE since the previous night - except HKS? I truly wonder how long she was either dead or dying?
Then HKS left her all covered up "sleeping." Did he tell Taz/Brigitte not to disturb her or what? I am curious what instructions he left them, if any.
I think he may have wanted to put the most distance and time betwee himself and her death as possible. Remember his "if you die, I'll go to jail" line (who told us that?). Either he allowed her to die, or she died by accident -- but, either way, he didn't want to be the one there when it happened IMO. But I am guessing she died that morning. When Brigitte found her she was already dead. But for how long?
I wish I had more confidence in Perper being able to tell us the actual time of death. Was it 9AM? 11AM? 1AM? It makes a bit of a difference. I thought they could pinpoint it with liver temp -- or is that just CSI stuff?
