<P> At the beginning of the story the killer is an unknown person . Miles was always obsessed with finding an answer so when someone told him that Otis Timson bragged about killing Missy he did not think twice and tried to arrest him . Eventually , Sarah 's brother , Brian , tells her that he was the killer but explains that everything was an accident . Sarah thinks about how to tell Miles and when she finally does Miles is furious and wants to punish Brian . After hearing Brian 's version of the story he went back to the crime scene and discovered that Brian 's story might be true . He later followed Brian to the cemetery and made him promise that he would do something important with his life and eventually lets him go free . Brian later became an emergency room physician and had saved six lives . </P>
