Debra and Angel identify the Ice Truck Killer as Neil Perry, a taxidermist with a history of mental illness and violence. After tracking down Perry to a sleazy motel, Debra and Angel arrest him where he gleefully confesses to the crimes. But when Dexter later meets Perry, something about his confession does not sit right with him. Lt. Laguerta sees the arrest of Perry as a way to further advance her political career, but feels betrayed when her superior, Captain Matthews takes the credit. Debra begins to have a meeting of minds with Rudy, the prosthetic manufacturer who works at the hospital, and asks him on a date. Meanwhile, Rita must try to adjust herself when Paul, her violent-tempered and recently paroled husband, shows up and throws his weight around by attempting to be compassionate to their children, Astor and Cody. Also, Dexter tries to cover up his past mistake when Jeremy Downs, one victim who Dexter allowed to escape, is arrested again for a murder charge.
