I think that is a great physical match, but was poor Connie living as a hermit all that time? It seems like somebody would have recognized her.
According to someone further up the thread, it looks like Connie wasn't reported missing. I guess because she left voluntarily? Did LE ever try to track her down? She was an adult who had the legal right to disappear, so did LE get involved? If this is her, she had to be making a living somehow, and the UIDs clothing was nice, so she was either working under her own name or some other.
