I talk to mom about this case and she mentioned a man's name, which I can't recall at the moment..my mom did say that the man was questioned..and nothing came of it she said. My mom believes the man that did this to her, she was dating him or seeing him.
Lisa it wouldn't hurt to follow up on that name even if Police cleared him at the time. That doesn't mean anything. just that they probably couldn't find enough evidence. He could have priors, or circumstances that could lead to other missing cases and similar to that of your great aunt.
