The wildlife management office may be closed Monday (Columbus Day) but I'll get in touch with them by Tuesday. I'll let y'all know what they are willing or not willing to do.
Regarding Brittney's well being. My initial, gut reaction was that she ran away, with the help of DH. Now, for months, I go back and forth as to her well being. If she is no longer living here on earth, I believe it's partly due to a woman scorned. There was no way out for DH because, IMO his wife held all of the cards. No matter what, Brittney is gone and IMO she went one way and her phone went the other. May peace be with her.
