In the fall of 2008, University of Colorado students who'd sought help from the school's Office of Victim Assistance told counselors they'd been the targets of date-rape drugs used at the same fraternity in Boulder.
"There was definitely a pattern of women being drugged at a particular fraternity," said Davian Gagne, who leads gender violence prevention at the office.
But the school's therapists said they are barred from telling police or anyone else any details about the alleged crimes - which have never been publicly acknowledged until now.
Neither the university nor the police could investigate "because we didn't tell them" the name of the fraternity, said CU Victim Assistance director Mary Friedrichs. "And we can't."
