Maybe Karr WORKED the Xmas Party. Caterers? Clean up?
According to the CNN report, which is all I had to go by, Karr claimed his brother worked for John Ramsey and was therefore able to get in the party and that he went with his brother.
Others are saying there's no record his brother worked for John (could he have worked for someone connected to John, but a step or two remote from John?), and are saying that everyone there knew everyone else and Karr would have been a stranger.
Your point (there to work, not as a guest) is worth pursuing IF the prosecutor is to clear up her case...either clear Karr of murder or charge him.
Surely the prosecutor is on this crucial detail like a fly on honey. If not, shame on her.
Every single person who was in that house on 12/23 has been questioned and DNA-sampled. They are ALL known to LE. *None* were under the umbrella of suspicion except the immediate family, because they could never be cleared.
The only reason we can't say the other party attendees have ALL been cleared is because no one has been cleared in the murder case - with the exception of Burke Ramsey. Maybe Fleet White, but the wording was murky. He requested it of LE, who said it didn't matter because if he came under suspicion he would be "uncleared."
