'CSI' Season 14: Marg Helgenberger returning for 300th episodeAdd to Favorites | CSI: Crime Scene Investigation
Marg Helgenberger, who left the long-running CBS drama a couple years ago, will make a return appearance as Catherine Willows in the milestone episode, which is scheduled to air Oct. 23.
Catherine's will return will be sparked by the reopening of a cold case from 14 years back. A former casino mogul becomes a suspect when someone is killed in his home, with the details similar to a case the team worked back in 2000.
The episode will include, per TVLine, what executive producer Don McGill is calling "faux-backs" -- newly filmed flashback scenes that feature Catherine, Nick ( George Eads) and other current cast members who were also around at the show's start.
Helgenberger left "CSI" in January 2012 as Catherine took a job with the FBI. She stars in CBS' midseason series "Intelligence," which is scheduled to premiere in February.
