CSI: Crime Scene Investigation has spent most of this week filming on location in Las Vegas, taking a break from their Los Angeles-based Universal Studios home. While the third episode of the season aired just two days ago, filming for the show’s ninth episode, “Strip Maul,” started production in Sin City at locations that include Fremont Street Experience and The Strip. Shelli Bergh continues to share photos with CSI Files, which you can find after the jump. She’s sent over some fantastic shots from the past two days that are definitely worth checking out!
