CSI episode name?!

CSI episode name?

Does anyone know the season/ episode number and name of the CSI episode in which they didn't catch the killer at first because he had a weird disease in which some of his DNA was different than the rest of his DNA.

Also!!! does anyone know the episode season/ number or name of the episode at the theme park/ fair where people get killed on the tunnel/ boat ride?

"Bloodlines" was the last episode from Season 4.

There were two episodes set at theme park/carnivals. One was the roller coaster one, "Turn of the Screws" also from Season 4. The episode where a little girl was killed on a tunnel boat ride at a carnival is Season 1's "Justice is Served." It was the B storyline in that episode.
