Marty tells detective Lutz "I've been taking some writing courses, and I've been tinkering around on this thing, off and on... 'True Crime'. Now that's the genre, not the title." When Lutz asks Marty if he's serious, Marty continues with, "Yeah, you know with what happened back in '95 and some other old cases...". Considering the date, title, and mention that it's "a genre, not a title", one can gather this to be a subtle nod to the '95 movie "True Crime" starring Alicia Silverstone and Kevin Dillon.
