I've run across this girl's casefile several times recently and have wondered if she has been checked against "Precious Doe".

The weaknesses are her listed height (5'5" according to NamUs), and the nearly four-year timeframe.
Charley Project has her listed at 5'0", so one of them is incorrect. BTW, there is also a 15 lb weight discrepancy between the two sources. (I e-mailed Meaghan at CP to see if her info is incorrect)
However, she was 16 at the time she disappeared, which means that she might have been still growing. We also don't know how recent her last height measurement was to her disappearance, so she might have been taller by that time.
And a four-year lag between running away and being murdered - with no contact with family or friends in the interim is not unheard of.
She looks quite similar to the drawing. Her age (plus 4 years) is about right, and the geographic comparison makes sense.
