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. The original detective comes out of retirement to help with the case, but his obsession with closing his decade-old case reminds Brenda a little too much of her own growing obsession with Philip Stoh, the slick lawyer she was unable to prove guilty of the rape and murder he tried to pin on a client.
