A couple of times over the past week Chima has spoken about an incident where she was raped and beaten. Her case was profiled on the History Channel's Cold Case Files, and she was the last victim of a serial rapist/murderer who was sentenced to death in 2003.
From the Cold Case Files' website:
Three years later, in February of 1999, 22-year-old Chima Benson sleeps soundly in her sorority house when she wakes up to a masked man in her bedroom. The man brutally beats and rapes Chima, before fleeing into the night. At the hospital semen is collected. The sample is compared to the DNA from the 1996 murders at the Peartree apartment complex, and confirmed to be a match.
