Development
Following the airing of the series finale of CSI: Crime Scene Investigation in 2015, series creator Anthony E. Zuiker said the future of the characters would be that "Grissom and Sara ... [would still be] sailing the oceans, ... saving the environment, ... [would have] children, and they would dedicate their lives to the betterment of humanity. ... Catherine would still be running the crime lab, ... [ Brass ] probably would retire, ... and DB probably is working in the private sector in Washington DC. And I think that all these characters would still have their toe in the crime water."

Soon after the cancellation of the last series in the franchise, CSI: Cyber, in 2016, it was announced that the producers were open to reviving the franchise. The CBS Entertainment president at the time, Glenn Geller, said, "We are incredibly proud of all CSI shows. It may come back in another incarnation." On February 10, 2020, it was announced that an event series sequel to CSI: Crime Scene Investigation was being discussed, from Jason Tracey, CBS Studios, and Jerry Bruckheimer Television, with Tracey, Jerry Bruckheimer, and Jonathan Littman as executive producers.

Zuiker teased that the second season will consist of at least 17 episodes. It was later revealed that the season would comprise 21 episodes in total.
