I do not believe any has. I recommend following Joe Asch’s Dartblog accounts, since he appears to be as connected as anyone. Heatherton’s problems apparently relate to an out-of-state incident (per the latest statement from his attorney) and not anything directly connected to the college or Hanover or even New Hampshire. The other two professors may be under investigation for the manner in which they conducted some recent research that (as I understand it) involved questions about the sexual attitudes of young female students after exposing them to images of some undefined nature. You have to go very overboard, I would think. to land in a criminal investigation for that sort of thing, but there are strict guidelines for experimentation with human subjects [remember the infamous Stanford prison experiment from many years ago?] and I suppose it’s possible that there could be criminal implications. Not my area of expertise, I fear.
