Tapped Out - 07/13/2009
Brenda’s team investigates the shooting death of a popular online “hook-up king” who was in the process of putting together a television pilot for a men’s cable network. The case goes awry when a police impersonator enters the picture. Meanwhile, Pope does a rotation as a regular member of Brenda’s squad to get a firsthand look at how the team works, but his experience isn’t exactly what he expected it would be.
Strike Three - 07/20/2009
A major shootout leaves two patrol cops and an 18-year-old boy dead with lots of unanswered questions as to what happened and who else might have been involved. The investigation is made all the more difficult by the involvement of Capt. Sharon Raydor (special guest star Mary McDonnell) of the Force Investigation Division.
Elysian Fields - 07/27/2009
The squad investigates the murder of a man who, 10 years ago, was the lead suspect in the murder of two girls. The state of the body indicates he was dragged behind a truck or SUV a full day before being shot twice in the head and dumped in Elysian Park. A detective comes out of retirement to help with the investigation, but his obsession with closing his decade-old case threatens Brenda’s own inquiry.
Identity Theft - 08/03/2009
A man (Bruce Davison) who confessed to murder while Brenda was away on her honeymoon gets details of the crime wrong during his allocution, causing Brenda to reopen the case. Her first thought is that he is trying to cover for his schizophrenic son (Michael Arden), whose doctor was the victim. Brenda’s investigation, however, is interrupted by a visit from her mother (Frances Sternhage), who hopes to pawn her troublesome niece (Sosie Bacon) off on Brenda and Fritz for the summer. Cynthia Watros also guest-stars.
