Meanwhile, Nick Stokes and Sara Sidle investigate a case where a man has been found shot dead and frozen to the floor of a cold storage room. A distraught man arrives at the station to report that he had been kidnapped because he had witnessed the murder and was stuffed in a trunk until he escaped.
Toronto-based filmmaker Michael McNamara, who had been working on his own documentary episode on furry fandom, said that the CSI episode "portrayed the community as a community of sexual deviants who like to have sex in fur costumes." and expressed concern that "it winds up giving the whole fandom a bad name, which made them nervous and camera-shy, so it was tricky to get their trust". He wrote that the deviancy "probably represents about two percent of fandom but it’s the one obviously that the press always gleefully jumps." Greg Gaudio of The Virginian-Pilot wrote that "The seamier side of the Furry Fandom – sexual behavior involving animal costumes and stuffed animals – has grabbed media attention in recent years, most notably as the subject of a 2003 episode of CSI: Crime Scene Investigation. The episode showed attendees at a furry convention engaging in a costume-clad orgy"; however, one of the furry fandom attendees he interviewed replied that such behavior "only involves a tiny percentage of furries and is not something that’s part of the local scene."
