Thanks, mikkismom- that is helpful to see what the parameters are.
Today, I stumbled across a missing person that I hadn't before.

Lori Lee Berens
Missing since
January 1985 from Winnipeg, Manitoba, Canada
Classification: Missing
Vital Statistics
Age at Time of Disappearance: 18 years old
Height and Weight at Time of Disappearance:
6'0; 225 lbs.
Distinguishing Characteristics: White female.
Dark brown hair; brown eyes.
Sorry, don't know how to post the pic. Her face shape isn't the same, but if you imagine her losing about 75 lbs or so, that could make her face shape less round. Also remember that you need to add 20 years or so to it.
I think the height, hair color and eye color is a good match. Also she left home after a fight with her family.
A main stumbling block would be the probability that she traveled from Canada all the way down to AZ (to steal ID) and to Texas, then proceeded to have a "normal" life from there without contacting her family.
