CSI Files previously posted pictures of rappers Yelawolf and Paul Wall on the set of CSI: Crime Scene Investigation. You can find two more pictures of the rappers below. The first contains Wall and Yelawolf on the ground (and includes a rude hand gesture), and the second features Wall alongside George Eads (Nick Stokes) and co-executive producer Dustin Lee Abraham. CSI: New York set designer Will Batts posted an interior shot of the sky bridge set we previously mentioned, and producer Jerry Bruckheimer shared an image of a sign featured on the CSI: NY set.
