Justin Kalior, the man arrested, talked with some website called Polygon about Sunday night. He claims he thought she was 20, not 17, and that he didn't give her any alcohol or have sex with her. His story is that he drove her to the con and they argued about leaving around midnight Sunday. He claims he contacted hotel security a little while later and was with them when she was found.
