US broadcast network CBS is expected to confirm the axing of long-running procedural CSI: Crime Scene Investigation tomorrow at its new season schedule launch.
Various US news outlets are reporting the Jerry Bruckheimer-produced show, which follows forensic investigators as they undertake cases, is not among 10 scripted series renewed for the 2015-16 season.
How CBS and studio sister CBS Television Studios plan to end the show is unclear, but the cancellation will leave new season show CSI: Cyber as the only continuing series in the franchise.
CSI: NY ended in 2013 after nine seasons and 197 episodes, and CSI: Miami was drawn to a close a year before that after 10 seasons and 232 eps.
CSI: Crime Scene Investigation currently stretches to 335 episodes, though the fourteenth was cut by four episodes to 18. Showrunner Carol Mendelsohn exited the programme in June last year.
Stalker is also thought to have been cancelled.
