This girl just showed up yesterday in NAMPN.

She is from Rialto - Right in the middle of the area where most of the Fiesta Foods markets are located. (The woman's head was found in a Fiesta Foods grocery bag within a backpack).
She went missing August 10, 2009. The head was found February 10, 2010.
The timeframe is a bit of a stretch. But IMO, she does resemble the Jane Doe.
ETA, her closed-mouth smile looks typical of someone who is self-conscious of her teeth. And despite the closed mouth, she does appear to have prominent teeth.
Agreed?
