Boston College is investigating a student who claimed anonymously on a Facebook "confessions" page that he had raped three women while at the college, The Boston Globe  reported. "Confessions" pages are popular on many colleges with students posting anonymously about their hook-ups, crushes or traumas. But the confession to three rapes quickly upset many people on the campus. College officials said that the student who wrote the post turned himself in to authorities and said that it was all a hoax. Paul J. Chebator, dean of students, sent an e-mail to the campus calling the post "very disturbing." Students have organized an event  for tonight to discuss the implications of the incident.
