I have totally changed my entire look of this case recently. The one thing that has turned me is that BD is seeing SA again, and FRIENDLY I might add.
I've been married for 30 years and love my husband dearly but if my daughter was missing, and my hub was named a suspect, no way in heck would I be talking to him, he would be out the door after I told him "Until the police has totally cleared you, I do not want to talk or see you" However not BD! My hinky meter went way off the chart when I learned she is friendly and seeing him again.
LE said she is not a POI, but I think LE has good reason for saying that even if they know it not to be a true statement. Catch my drift?
