Sterling FitchPlayed by Kacey Rohl
Sterling Fitch is Rosie Larsen's best friend. The two hang out at the Halloween dance and are seen together in video footage now in police custody. At school before Rosie's body is discovered, Sterling, her nose mysteriously bleeding, lies to Principal Meyers and her teacher, Bennet Ahmed, about Rosie spending the weekend at her house. Later, she bikes to a tweaker hangout, where Kris Echols hints that Rosie hooked up with Jasper Ames. Questioned back at school by Sarah, Sterling adjusts her story, saying she lost track of Rosie at the dance and assumed she was with Jasper.
