Caitlin La Marque is a college student who published a list of people she had sexual dalliances with, which embarrassed and humiliated numerous people, from her partners even to people they cheated on. Jill's boyfriend was one dalliance, leading to Jill breaking up with him.
As revenge, Jill invited Caitlin to a house party she was hosting just so Caitlin could be humiliated in front of the guests. It would, and the two women took their confrontation to Jill's bedroom. Jill got furious during the argument and smashed Caitlin's head in the mirror. Horrified but shameless and believing Caitlin would wake up, Jill covered her with a jacket and went back to the party. Unfortunately, Caitlin, covered in marker scrawlings all over her face while she was unconscious, died from hemorrhaging. She was also neglected in emergency care and raped by paramedic Clark Tinta, with the backing of colleague Mike O'Doole. (SVU: "Rescue")
