so if Reade, who was with a friend, swiped his card after a short walk to his dorm could the cabbie have gotten back to 610 befor 12:55? The ladies were gone when police arrived, and he overheard the argument...someone has the time wrong.
I think that when Reade got back to the dorm, he didn't go in immediately. Isn't there a phone call between when he was dropped off and when he entered the dorm?
