Two former Dartmouth students have signed on as plaintiffs to an ongoing lawsuit that alleges that for over 16 years College officials ignored evidence of sexual misconduct by three former psychological and brain sciences professors. In an amended version of the original plaintiffs’ complaint filed yesterday in the U.S. District Court of New Hampshire, the two former students bring forward additional allegations of sexual assault and harassment, adding to an already significant and graphic list of charges made by seven other women who allege that the three PBS professors turned the department into a “21st century Animal House.”
