Good point. So far there’s nothing to definitively link the two with having a past relationship. He may have been stalking her, and she may have known he was stalking her, but the article only says she had a “new” boyfriend who had dropped her off just prior to the meltdown.
Not yet. I note he was six years older than she was.
Not in the media, at least. I'd speculate that the "rambling note" makes the link, though.
Just a guess, but she was probably nice to him a time or two, and he took it as an excuse to stalk her.
My guess is that she talked to him once or twice, was nice to him, and that was enough for him to think they had a relationship she was “not keeping up” on her end. He probably stalked her big time, put a lot of pressure on her, and being the girl she was , she probably thought it wasn’t worth getting him in trouble for, that it would go away, that a new boyfriend would take care of it. Everything I know about life tells me that is probably the case.
Not yet.
But she will be.
