How can I find CSI episodes where the 'exchange principle' is quoted?

[cstagnara]

I am trying to gather a gift my my grandma. The thing is that Edmond Locard is my great great grandfather and I would like to make a compilation to my grandmother of episode where his name or theory is quoted. So far I only found one episode:
- CSI Miami : Out of Time (Saison 8, Episode 1)

Thanks for your help

Welcome to the board, cstagnara. I only have a few of the dvds, but I did a yahoo search and found the following. In the original CSI (the Vegas team), season 1 episode 16, "Too Tough to Die", this quote takes place:

Nick (about the victim): Did she know the guy? Did he use his car or hers?
Grissom: Locard's principle: He took a piece of her away with him and he left a piece of himself here. (beat) We get to find it.

(It was the one-liner just before the opening theme song.)

Edited to add:
Also found this one from the original CSI, season 1, episode 23, "The strip Strangler":

"Everybody knows white cotton fibers aren't like fingerprints. They can't be traced. You don't get a ... match on a towel."
"In theory. But the truth is every object is changed by its owner. By his habits. His ... washing machine, for instance. His detergent."
"The totality of microscopic elements. It's Locard's Theory."
-- Syd Goggle and Gil Grissom (The Strip Strangler)
