To your first assertion: Where did this come from? When did either of them even suggest such a thing? They had elaborate and shifting stories about being together, surfing the internet, watching a movie, reading Harry Potter books, making love, not being together, smoking pot, not remembering what they were doing, eating variously at 9 pm, 10 pm or 11 pm, playing with bleeding fish, looking at a swamp forming under the sink, and so forth. Those are just the stories you and I can get from publicly available articles. I haven't even included AK's statements about witnessing Patrick sexually assaulting and murdering her roommate or the Kate Mansey interview with RS.
