SEASON 4, EPISODE 417 - During an excavation, construction workers uncover the decomposed and battered body of Maurice Hall (Nathan Halliday), a sensitive grocery clerk who disappeared in a working-class town in 1984. Rush learns that Maurice was listed as missing at the time, and no one knew he was dead. His father, who always favored Maurice's ambitious, athletic older brother, tells Rush that Maurice had been behaving strangely before his disappearance. But his brother later confides details about Maurice's activities that his father never knew about--activities that could get someone killed in that neighborhood.
