My guess is that woman is NOT a quilter. Quilters are good people who wouldn't take advantage of another person. She probably bought the frame at a yard sale or a flea market at a low price because of the missing pieces. You might try an ad in the paper to ask if anyone has rails for that model. There's an off-chance that whoever she bought it from (if she did that) has the other pieces. In the meantime, contact the sheriff's office and file a report. Such a dishonest person may be well-known there.
