This has been such a sad story to follow.
My guess/theory is that the perpetrator is someone who lives close Jessica's home. Maybe not right on her street, but very close. While it could be someone with a history or a record, I tend to doubt that right now. His actions don't sound like what someone with 'experience' would do. My gut feeling is that it's somebody no one would suspect who did this impulsively, finally acting on something he's thought about doing for a while. The opportunity presented itself, and he acted. After the fact he faced the problem of disposal, and figured that he'd delay or prevent getting caught by scattering poor Jessica's body and other evidence in different places. He couldn't go too far away because his absence might be noticed if he was gone too long, but it had to be out of the neighborhood to shift the focus elsewhere. That's all just my guesswork at this point.
Has LE said how long the body had been there?
