I feel it is very possible that DM was on something the night this happened. I don’t mean that to vilify her at all - I say this because I was in college once and experimented on occasion as many students do. Lucky for me it was not a common occurrence, but I do know on those rare occasions that I did, I would have been pretty terrified to speak with police. Possibly she thought her fear was exaggerated by whatever she had taken that night (Molly or shrooms are very popular in the party scene and could provoke paranoia in certain people, or a sense of euphoria which would confuse the mind on what is really happening.) Of course this is just a guess. I do feel it would easily explain why she was hesitant to call police right away. It is not rare at all to feel a sense of panic or paranoia, especially if you rarely indulge in those types of drugs. I could be wrong, but my gut is saying this possibly played a role in her reaction to the scary situation. I also think she may not admit this possibility right away, because I know the times that I experimented, I wouldn’t have wanted family or friends to know. She may have not even admitted it yet, but it is important because it helps everyone understand what happened.
