I didn't think the first victims name started with a T but with a Z. Unless she has a more formal name I am not aware of.
Edit: I see now that the CNN article states both the victims names. Terrible, terrible tragedy.
My opinion is that she's either checked herself in somewhere and not contacted anyone (that is the most hopeful scenario), or ran off somewhere in woods, fell, etc and passed as a result of being lost/injured. It's unfortunate, I have been hoping they'd find her somewhere safe.
It's been a almost a month, she can't be simply lying somewhere hurt. If she fell in somewhere/something she had no access to food or water, there'd me no chance of survival for this length of time.
