I agree it doesnt seem likely that there was enough time for this to happen. I wonder if the lady has her days mixed up and it was Friday?
If he (or they, if C was there) met her close to 530 as planned, I think it could fit. Especially since LE STILL is hopeful she's alive. And really they seem to have been confident in that all along...it's always been them saying they believed she was abducted or taken, and not saying killed. And since they're still saying that even after hours with him, it makes me think there's a legit reason.
Anyway, heres how i see it being possible time wise
House at 530, scuffle in the house after a few minutes trying to take her down, she fights in the process and he gets scratched.
Leave by 6, take her to a cabin or something (however mud plays in) and restrain her and leave her.
So be en route back home nearing 7. Be washing the car around dusk at 730.
:dunno: Seems like taking her alive - especially if he told her to cooperate or he'd go after her family or one of the grand kids or or something (heck, maybe it could be a ransom thing and that being why LE thought she was still alive?) - would be a whole lot faster than killing her and covering up a body.
Frankly I hope they are searching all vacant houses cause he had sure been mentioning homes a lot. Maybe he scoped out a vacant one (and likely not for sale) that looked like the one he seemed to move into...boarded up windows, maybe where a friend lived and could watch things? :thinking:
