Meanwhile, Morgan, Sara and Finn are met with a shootout at a forensics conference ("Girls Gone Wilder"), D.B. turns to Avery Ryan for advice on the psychology of killers ("The Twin Paradox"), and the CSIs reopen a ten-year-old investigation ("Dead Woods"). Also this season, a chrome-covered victim perplexes the investigators ("The Last Ride"), the abduction of two teenagers leads to a surprising offer for Nick ("Under My Skin"), murder memorabilia brings back bad memories of the team ("Merchants of Menace"), Stokes leaves Las Vegas, and Finlay is left comatose after coming face to face with the Gig Harbor Killer ("The End Game"). == Cast ==

In June 2014, it was announced that showrunner Carol Mendelsohn would be leaving the show after 14 years. Speaking to The Hollywood Reporter, Mendelsohn stated, "It's been a long and amazing journey, and I am so proud of CSI's continued success. In handing over the helm to my dear friend and partner, Don McGill, I know he and our CSI team will carry on brilliantly what we've all created together. CSI, its cast and crew, writers and directors, will always be my family. I have learned so much from each and every one of them. About writing, producing and life. For that, and so much more, I am forever grateful." Don McGill became the lone showrunner for season fifteen. Starting with this season, the show moved to Sundays at 10:00p.m, except for episode 16, which had a special Tuesday at 10:00 p.m. airing on January 27, 2015. ==Episodes==
