"Obsessively calling and texting her in the last few months of her life."
I don't think the police would just go with that if they didn't have Julie's cell phone records and texts to back it up. You don't take the family's word on something like that before making a statement to that effect. They're not gonna say he's obsessed if the affection or whatever was mutual.
Too bad ol' Bill deleted his Facebook. I would be interested to see whether they were friends. And since I'm now stalking the stalker, I wonder why I don't see any pictures of him. You know, since he was her entire world for six years.
But I mean, stalkers do things that most people would find unrealistic. They're obsessed; they find a way. (See also: Jodi Arias writing letters to Travis's grandmother and calling the detective to offer assistance and attending the memorial).
I believe the police have ruled out simple error even if they haven't made a public statement to that effect.
And I'm sticking to my theory that this guy bribed Dick Tips for access to the body, then buried her somewhere that had special meaning to them at some point.
