lpowers@rgj.com The University of Nevada, Reno chapter of the Pi Beta Phi sorority has been suspended until mid-February after two calls were made in October to a hazing hotline concerning activities at the sorority, a spokeswoman for the sorority's national headquarters in Missouri said Thursday. "Because the investigation is ongoing, we cannot share any specifics about the allegations nor can we share which members are allegedly involved," Eily Cummings, Pi Beta Phi's marketing and communications director, said in an emailed statement.
