I am VERY behind on this case/threads, so forgive me for posting anything already discussed or ruled out.
On my daily morning CBS "Crimesider" blog cruise today, I stumbled upon a post stating that Hailey's mother's (BD) boyfriend is now a person of interest, and BD herself is now looking very shady, after failing a poly and cops finding news articles about adolescent sex crime/serial murder cases in her car. WHOA. More here:

I think Mom and Boyfriend JUST implicated themselves.
Also, BD says:
Ummm, how about "my little girl", or "my daughter", and not just "a 13-year-old"???? Who cares about YOU? RED FLAG.
