IMO something is odd about this case. I don’t think of her as a young teen that willingly walked off. I see a child, possibly with disabilities that cause her to act younger than her age. She was wearing blue pj’s with stars, blue circular sunglasses and carrying a pink purse with unicorns. That sounds childish to me.
The lack of media coverage and attention puzzles me. She went missing in a rural area. Why no searches? Why no pleas from her family? Why the delay in the missing child alert? When was she reported missing? Who reported her missing? Last seen in the ‘early morning hours’ on May 15. That was a Saturday...early morning like 5 am after sleeping? Or 1:00 am Saturday morning/Friday night?
Sounds like LE might know something bad has happened and issued the alert as a way to generate leads and gather evidence. They are investigating - likely questioning the family, neighbors and acquaintances, etc. - but not searching.
