Hi Skigirl, Thank you for your interest in Joan's case. When taken as an isolated explanation, going back to school early seems very plausible. The graduate program at Harvard was very demanding. I am putting it in context with other things known. The original plan was to ride back with her sister on Sunday. There was a planned visit from a friend in NJ that was cancelled. No classmates came forward with statements Joan had planned to meet with them on Sunday as reported. Joan never mentioned going back early when we spoke on Thanksgiving. It is out of character for the family changing arranged plans. The biggest factor I look at is what happened to Joan when she went back early. She tapped on the window of a Town Taxi and driver Fenton Moore put her bag in the trunk of the cab. Joan announced a man was with her. The man exchanged words with the cabbie over a very heavy suitcase. The man said "we" don't want to take this cab. Joan's bag was removed from the trunk and Joan and the man got into a blue car. That is where Joan disappeared. She was missing for eight and a half years before her remains surfaced. She had a 2" x 4" hole in the right side of her head. She was stripped of all clothing. She was thrown out in a black plastic trash bag, and buried in a shallow grave in a remote wooded area. To examine what happened to Joan, I am looking for the discrepancies, the nuances, things that do not make sense or are out of character. It does not make sense in the context of other things that Joan cut her break short to go back to hit the books.
