Synopsis by Hal Erickson
CSI's fourth season gets off to a lively start with this concluding episode of a two-part story. While the CSI team investigates a double murder, two more bodies turn up. It may be a serial killing -- and worse, a police officer might be involved. The case becomes even more complex when the two likeliest suspects are also murdered. Meanwhile, Catherine (Marg Helgenberger) tries to cope with the murder trial of her casino-owner father, Sam Braun, as she joins Sara (Jorja Fox) in probing the bizarre demise of a college football fan.
