BBM. I agree, we are limited only what has been linked through social media. But if you have a list of another WHO (or multiple), I'd love to see it. I don't think it's uncommon that we are focusing on the SG as this is the ONLY house that has not only been reported by MSM, but also the only one leaked through local SM pages. Wouldn't people be all over posting it online if their neighbors house was searched or somehow involved? They didn't waste time jumping on the Berkley page to bring attention to the Oxford residence, later confirmed through MSM and LE. I just haven't seen any reason to believe that someone other than the SG (who also had a sick spouse) was living at this residence.
As for the return home, it was reported very earlier on that DS told her friend she had planned to drop by apartment and grab a bag before heading over to her home that evening to spend the night. It's later been confirmed by family and LE that neither believe she ever made it into her apartment or was the one to park her JEEP there.
No one has been formally named a POI but discussing who appears to be the only lead in the case doesn't mean we are closed off to others or an accomplice. At least I'm not, I just don't see anyone else at this point. All MOO.
