Yes, that struck me the moment I started listening to the radio show.
In that one blog posting and comments alone several significant things are mentioned that seem odd after 10 months!
The mother has never talked to the Grandmother, and she does not even know if the Grandmother was home when Morgan visited her house the night she died.
When asked if the panic button was still by Morgan's bed when she died, the mother says she "just realized" she didn't see it on the nightstand, and then went to look and found it on the floor. I interpret that to mean she "just realized NOW" in response to the blog query, 10 months later?
Then the mother mentions her daughter may have been drugged/poisoned months earlier at the SAME HOUSE???
Also notice the comment referencing a mystery WS poster near the end of the page at 4:27. <modsnip>
