Lois Creen is one of three rape victims of Harvey Denis, along with Victoria Kraft and Jennifer Neal. She struggled the worst with recovering from the trauma of the rape and physical assaults she endured, fearing what she'd be in danger of even leaving her apartment.
Creen accompanied Kraft in speaking to Neal, who shared a Quakers church with Denis, to get him to reveal his name. Creen herself tried to start with pleas, but when the attempts became more emotional Kraft and Neal still refused to turn him in, Creen lost it and screamed at Neal she wanted answers and Denis punished after all she herself suffered. When Neal wished her peace on her way out, Creen just shouted her away and cried.
Neal was arrested on obstruction, whether released later or not, and Denis was arrested and imprisoned once found. (SVU: "Limitations")
