Such an ignoramus. She is not smart... just average, but she excels at manipulation, obsessiveness and the integration of factoids and misc info into her dialog.
She is just so dang WEIRD! ICK!
You know, I hate to say it but, they say men usually act out by using overt behavior (can use force/acts of aggression against target, verbal communication can become derogatory) and women will tend to use mental deception (use trickery to create a hostile environment). Either party can use whatever weapon in varying degrees, it depends on whatever is triggering them (need not require anyone has a personal relationship or merited such response in the slightest).
My guess is, she knew she was dangerous in her pre-adolescence either way. She must have settled on pathological lying and the manipulation of one's reality as akin to the release of her inner violence... sabotage one's mind instead of physical bodies. Well, I don't doubt she's had quite the dangerous disdain for smaller animals from time to time. Either way, the only reason she didn't destroy a body for everyone to see earlier, would have simply been because she didn't have the mechanisms to evade police. I think everyone in Yreka would have known about her and ratted her out ASAP too. It was however, a smaller community, perhaps too risky to visibly commit an atrocious crime.
She forged her 'support network' from PPL (either way, quite the source of income and additional aide from Gus).
But with this girl, the way others are able to pick up on her pattern, I wouldn't be surprised if she resided in every state in the USA... and every community she came into contact with went... "I have the feeling Jodi Arias did this..!"
No need to worry, she'd have left behind her palm print mixed with victim's blood, photos, and if that's not enough, will keep the receipts and literal road map in her safe deposit box....
