"I am afraid we are going to lose track of this story now;
we're not going to get the details/answers we all want."
"Did they know her and ask somebody to check
on her kids that very night?"
It is all there in these threads. Would help if they
could be searched more efficiently.
Do you know what day they released that audiotape?
IIRC, Shelton said someone should check on the kids during the 911 call. It was released and the audio was on blueline(?) at one time "Someone should probably check on the young ones" something like that. It read and sounded as if she was known to them.
She also asked Brian Taylor to check on the kids according to the N&O article. He said he told her he would, but he did not.
