The issue of entry, I wonder as other Sleuthers have suggested that she was brought there for a party she thought was legit but somehow was intoxicated at the time and was actually not in the house technically but was in the arms of someone and put on the balcony and left there. But again that has an aspect of complicity at the very least and someone is culpable in that. To me that seems it was intentional. As if she was intoxicated she would wake up in a few hours but did not. So the aspect of a party is IMO simplifying what happened and is making it sound as if no one is culpable. In the end that is what I'm afraid the police believe. So to me this doesn't make sense either. Honestly IMO I don't think LE would make this assumption if there were more answers. So IMO the answers just aren't there. And one of the things that stumps them is the issue of entry.
