S7E13 The Ultimate Sin

After thirty years of silence, a guilt-ridden man finally breaks. Haunted by a young girl's murder he helped cover up as a teenager, he confesses to a priest, setting off a chain of events that forces the town to confront a buried crime. As old secrets surface and alibis crumble, the truth behind her death proves more twisted—and closer to home—than anyone ever imagined.
