The Wilsons go on television to offer a reward. The newspapers are making the Homicide unit look bad and Barnfather wants quick resolution to the case. The man (and his wife) who gave up Junior Bunk are murdered; Falsone and Lewis investigate. The only survivor, their young son, is brought in to find out what he remembers. His memories-- and a recorded phone message-- lead Stivers to believe a former member of the Narcotics unit is involved. The officer cops to a deal that implicates Georgia Rae Mahoney, though Giardella doesn't want to pursue that yet. Falsone's questioning of the Mahoney shooting leads Cox to doubt her actions at the time of the investigation. Incriminating evidence leads the detectives to Hal Wilson being their prime suspect. Frank goes to interview Felix and Hal Wilson; son and father confront some long-standing issues. Hal's confession is inadmissible in court, the Wilsons leave the Baltimore area, and the case remains officially open. (thetvdb.com)
