The Strip Strangler

A serial killer is on the loose, and the CSIs race to find the answers. The killer has a clear knowledge of forensics and has done an excellent job of leaving no clues, however. As the investigation stalls, the FBI are called in by the Sheriff, which angers Gil to the point where, duee to his intransigence, he is ordered to stand down from the case and let the FBI supervise things. His CSIs, though, keep him apprised of their findings, though Gil can't be a direct part of the investigation.
