The part in bold in your post #11618 clarifies it, makes it clear what you have been saying.
you really should have known that if you had been paying attention. That information has been around for years, it's been referred to over and over. She said she was flying out to Boston that same day, according to Susan, and Susan also said, at that early interview, that she never saw her again.
I'll say it again and bold the entire phrase:
...there's no way she would have said she was going to visit her husband in Boston because he was at Harvard as no one knew then that he was ever going to be going to Harvard. Stanley Ann flew out that day to go to Boston, and what we should be asking, is...if she was really going to Boston, who did she know there?
