There is brief discussion and suspicion mentioned at various points that the murder of a teenage girl was sexually motivated. It is revealed and mentioned throughout that an adult male photographer was taking 'glamour' shots of teenage girls. In episode 3, a character talks about a statutory crime which occurred when she was 15 and of parties she was told about where young girls 'met' older, wealthy men. SPOILER: They turn out to be irrelevant to the story, and the conversation in episode 3 is the only one with any detail on the subject.
