Gabby - this isn't directed at you, as I think yours was just a typo, but I do want to re-emphasize that AA is the person who was found by MSM and when interviewed he said he saw the key/purse on the floor around 3 AM. Afterward, his friend (no ID known) moved them to the railing.
There is absolutely NOTHING anywhere that ties AA to the case other than he saw keys.
AB is a person who is rumored to reside with ZO, and again, there is NOTHING to say that he has any involvement in this case. His involvement has come by way of his friendship with ZO, and his appearance possibly fitting a description of a witness that sighted LS with a man at a time or place unverified by LE.
I think it is good that we are aware of the people around and about, but IMHO (and MHO only) recently, we have been a little too quick to associate random people with criminal activity without substantiation.
The person rumored to be JRs guest is especially troublesome. One site claims they attended the same HS, they did not. And the only thing that this person has done is to be from Michigan and to be eating a meal in Bloomington. There is no reason this person should be even mentioned.
jmho and all that... I think the internet is getting a little too witch-hunty for my tastes on this case.
