At the beginning of the movie, Dave, Jimmy, and Sean were depicted as young boys playing in the street. A policeman comes along and takes Dave away with him. The "policeman" is actually a hebephile (one with a preference for a sexual partner who appears to be of a specific age). Days later, when Dave finally escapes, he is marked by everyone in the neighborhood as "damaged goods." After that, it becomes easy to blame Dave for doing criminal things to others, based on the erroneous assumption that "what goes around comes around." On a narrative level, the trauma is also what ultimately causes Dave's death, although indirectly. Obviously, very few others still know about his ordeal, since everybody chose to simply bury the subject. Dave never got counselling to cope with the event, he hasn't even told his wife Celeste. On the night of the murder, Dave attacks and kills a pedophile in an attempt to save a young boy from a fate similar to his. However, his inability to talk about his motives causes him to come up with a fake story about a mugger, which he tells his wife Celeste. Celeste becomes suspicious when she cannot find any mentioning of a wounded mugger in the newspapers. This becomes worse when she hears Dave give different statements as to the cause of his hand injury; if it was from fending off a mugger, why not come clean about it? His increasing mental instability starts to frighten her to the point where she shares the suspicion with Jimmy, which ultimately leads to Dave's death.
