Eric Szmanda addresses another possible CSI: Vegas return for his character. A follow-up to CSI: Crime Scene Investigation, the series tracks a team of forensic investigators who employ new techniques to analyze evidence and protect the streets of Sin City. CSI: Vegas premiered on CBS back in 2021 and featured several original cast members, including William Petersen and Jorja Fox. Szmanda portrayed Greg Sanders, a main character throughout most of CSI, and while he was revealed to have left the Crime Lab before the events of the sequel, he eventually returned towards the end of season 2.
