Which CSI season-one episode had production code 102 but aired as episode 11?

The CSI season-one episode with production code 102 that aired as episode 11 was “The I-15 Murders.”

Production codes reflect the order in which episodes were made, not necessarily the order in which CBS broadcast them. “The I-15 Murders” was produced as the third episode of season one, carrying code 102, but scheduling changes moved it much later in the broadcast lineup.

It eventually aired on January 12, 2001, as the season’s 11th episode. The story follows Grissom, Catherine and Brass investigating multiple deaths near Interstate 15, while Nick handles a separate case involving a murdered prostitute. The title refers to the major highway linking Las Vegas with Southern California and Utah.

A common mix-up is confusing the production code with the episode number. “Unfriendly Skies” was season one’s ninth broadcast episode, while “Fahrenheit 932” followed “The I-15 Murders” as episode 12. The code 102 is therefore a production identifier, not a missing or alternate episode number.
