I guess it's always theoretically possible that someone thought Betsy was an informant when she wasn't. But I would think there would have been someone else who might have known about this had it actually happened that way. A "true believer" would have likely talked about the great deed they did for the "movement." The ex-BIL spoke with her, as far as I know, on the phone when she called her family to let them know she was fine and was back at school. I think the death penalty letter was mainly because of her sister's involvement in Prison Ministry, since that was a hotbutton issue in '72 when the letter was written. In '79 a postcard was mailed to the State Police's George Keibler, one of the original investigators, saying "You never caught the guy who killed that **** in the library over the holiday. We'll be back." It was mailed from a southern state. It seemed most likely that she had been stabbed either from behind (very odd angle though) or from the front, at about a 45 degree angle, as though she was facing some shelves, someone came down the aisle, and she turned slightly to address them or acknowledge/see who it was. I may not be around much longer, it's been a pleasure talking with all of you this past year.
