I just want to insert a teeny bit of logic about the human trafficking theory. First I want to say I 100% believe SP could easily be trafficked.
The growers in the hills take captives for this. I don't have an article to link readily, but in the past 28 days I've definitely read a few stories, blogs and tweets about it. The girls (and boys) are typically drawn to do the clipping for easy cash. But if your a little bit pretty you have more value in other ways besides clipping. When they are done with you, they don't release you. They kill you.
If you peek around the escort section of craigslist (not recommended for the faint of heart), then read articles (they are available via Google) from girls/women who got out you will see that generally 2-3 people hold captive 1-2 girls for YEARS and brand them with a hard-to-hide tattoo, sexually peddle them, sell them, but never ever ever let them out of their sights while they 'own' them. Some girls/boys get away under extenuating circumstances, but usually they just get used up.
And if they're monitored 24/7, who are they going to ask for help from, a jon? Those creepers know exactly the situation, and they're counting on not getting caught. They aren't going to say a word or they won't get future service, iykwim.
Most of these missing youths never ever reappear in society, not counting the ones who got away somehow. Yes, maybe a few are released after their income potential diminishes, but where are the rest?
My logic insertion is this.... In the case of SP... If they thought she was traffickable, it could be that they got mad when they realized her age after abduction and didn't want her. Still, I honestly doubt they would have spent all of their precious time torturing her. I think they just would have killed her and buried her in the woods.
And if they took her for any other reason than the one we don't yet know about, I think they would have just killed her well before risking being caught with her.
And with all the national coverage, they took great risk by releasing her. They could have easily killed her, buried her, and went on about their lives and probably gotten away with it.
Therefore, I don't believe this is a case of potential trafficking. I think this is a targeted message of hate. SP mother ay not even be the target, just the messenger. Someone(s) is very angry and hateful, and I think this is a hate crime meant to hurt whomever the message is for, and all who surround that person. I think we will see another "message" find its way into their world at some point. JMO
