Riley Porter is a rapist and assailant who attacked a couple as a favor to Chris Carnasis, a fellow member of an online incel community, who in turn raped a woman Riley felt had rejected him.
Riley was eventually arrested and, after the Special Victims Unit realized he traded rapes with someone, identified Chris as the other rapist. He then took a plea deal in which he was sentenced to ten years in prison for rape and assault. (SVU: "Revenge")
