S17·E12 Real Crime

DC Kate Spears is assigned to a domestic violence case, but is alarmed when DC Mickey Webb realises the perpetrator, Neil Hayes, is also a suspect in a series of truck hijackings he is investigating, and requests he be bailed so he can lead them to the gang. Spears's sympathy for the victim, Lisa Hayes, starts to wear thin when she refuses to press charges, harasses Spears at work, and then is discovered to be having an affair with Hayes's boss.
