Police yellow tape and crime scene investigators at Frank’s Restaurant on West Olive Avenue here in Burbank today. There were criminalists on the scene, but not from any local law enforcement agency. It’s part of the filming of an episode of the long running TV crime drama, “CSI: Las Vegas.” The shoot began on Thursday and is expected to wrap in the early hours of Saturday morning. Love to see film productions shooting in B-town — keeping entertainment jobs in the Southland.
