If it follows the usual CSI plotline, the rubber suit fetish is what lead to the decedant becoming the decedant. This episode sounds like a variation of ‘Fur and Loathing in Las Vegas’, where it was people in animal costumes.
Saw that one, too. CSI comes out with some really bizarre stories. I had a friend who worked in production for the original CSI. She said the stories are pretty much based on actual events. Eeeeeeyoooo.
