CSI: Crime Scene Investigation
CSI: Crime Scene Investigation, often referred to as CSI: Las Vegas or simply CSI, is an American crime drama created by American television writer and producer Anthony Zuiker for CBS. It ran from 2000 to 2015 and was the first instalment of the hugely popular CSI franchise. The series follows a team of expert crime-scene investigators and forensic experts from the Las Vegas Police Department as they look for physical evidence to solve murder cases.

Following his departure during the ninth season of the show, CSI assistant supervisor Catherine Willows, portrayed by American actress Marg Helgenberger (All Rise, Hell's Kitchen), takes over Grissom's position as supervisor of the team.
