I believe the only thing confirmed by LE is that RM did not come home and that was via IM...and i dont ever recall a public statement by LE. PLease correct me if im wrong.
I have learned a valuable lesson from this case (sincerely): be very careful about what you *know* is fact (and can be substantiated), versus what people (other than LE) say/hear/think. Sometimes, if you hear something repeated enough, it becomes a "fact" in your head. :facepalm:
