I just thought that I would make an effort to help. There was a segment on the Channel 2 News in Houston about a woman that was found with injuries to her head and she has no idea who she is or where she belongs. Fingerprinting has resulted in no matches and no missing person reports have matched up with her. If you are interested or think you might know her here is the link to the segment and article.
