S2·E9 Cop Hunt

A woman who was driving home late at night is found beaten and raped after being stopped by a police officer for a traffic violation. After talking to the woman, Mannion discovers that this is the latest in a series of attacks allegedly perpetrated by a police officer. Now, after Mannion conducts an internal investigation of his officers and fingers start pointing at Cutter, Debreno is thrown for a loop when his estranged wife (Farentino) informs him that she was attacked in the same exact way.

Meanwhile, Preston Kembridge, a mayoral candidate, tempts Nick with an offer to run his campaign. (from CBS)
