CSI: Crime Scene Investigation, Season 1

Grissom:
Look ... if this wire burned from the inside out then the fire started in the wall not on the closet floor. Discoloration throughout the conductor. It burned from the inside out. The cause of this fire was an electrical overload in the wall.

Eclie:
All right, you say wall, I say floor. We differ on points of origin. The jury's only going to hear one word: Gasoline.

Grissom:
Speaking of which ... where's your accelerant analysis work?

Ecklie:
I personally swabbed the closet floor. Found traces of hydrocarbon chains confirming gasoline. Leave it alone, Gil. The DA agrees with me on this.

Grissom:
Too many unanswered questions, Conrad. This case should not be going to trial yet.

Ecklie:
No, there's only one unanswered question. Why was there accelerant in the closet? Only one person knows. And that's why he's looking at the death penalty.
