The incident is still under investigation by police, the university and Pi Kappa Phi's national office. All three have yet to release additional details as to what transpired.

"Radford University takes these allegations seriously, will investigate thoroughly the facts of the situation and will hold participants accountable for their actions," Carpenter wrote in an email to The Roanoke Times." Radford University has and will continue to cooperate with the City of Radford Police Department in the investigation into the allegations."

The Radford chapter of Pi Kappa Phi was founded in 1978 and has been involved in at least one other controversy since that time.

The chapter lost its university affiliation in 1996 after 18-year-old Radford freshman Valerie Cole died of alcohol poisoning after attending Pi Kappa Phi and Chi Phi fraternity parties with friends. An autopsy determined her blood-alcohol level was .31 percent, almost four times the legal standard of intoxication.
