I joined Websleuths to say this. I’ve been obsessed with missing people for a few years now but this one is in my “backyard” and something about it haunts me.
As Lanny said, I think the Vandy clothes are a distraction or she just needed new clothes. Maybe someone needed her to “blend in.” If she were a student of such a prestigious university, she would have been reported missing—even if she were an international student.
The familiarity with the rural setting of where she was dumped suggests the killer was local. Police have been unable to determine her cause of death but state no visible trauma, so possibly asphyxiation or drug overdose. My gut tells me she was a trafficking victim from somewhere other than TN.
