The unnamed "Runaway Rapist" is a serial rapist of young women and teenage girls, who was briefly suspected in the murder of Shannon Coyle. Although he was cleared due to inconsistencies in the M.O. of Coyle's murder, the rapist was identified by a woman who was nearly attacked but rescued when the rapist was arrested.
The rapist was found guilty of eleven rapes and one attempted rape and was imprisoned. (SVU: "Families")
