Atticus does not want Jem and Scout to be present at Tom Robinson's trial. No seat is available on the main floor, so by invitation of Rev. Sykes, Jem, Scout, and Dill watch from the colored balcony. Atticus establishes that the accusers—Mayella and her father, Bob Ewell, the town drunk—are lying. It also becomes clear that the friendless Mayella made sexual advances toward Tom, and that her father caught her and beat her. Despite significant evidence of Tom's innocence, the jury convicts him. Jem's faith in justice becomes badly shaken, as is Atticus', when the hapless Tom is shot and killed while trying to escape from prison.
