"CSI" is ending its 15-year run.

Multiple sources, including Vulture, confirmed the cancellation of "CSI" which wrapped its fifteenth season in February. Two insiders, however, have tipped the news outlet that a two-hour long TV movie will air next season to wrap up loose ends of the show. The network hasn't issued an official statement yet regarding the possibility of a "CSI" film.

Entertainment Weekly wrote that original "CSI" star William Petersen could return for the TV movie. The actor portrayed the character of Gil Grissom on the popular crime drama.

The series' spin-off show titled "CSI: Cyber" has a more pleasant fate. The Hollywood Reporter stated that "CSI: Cyber," which is headlined by Oscar-winner Patricia Arquette, is renewed for a second season. The drama hails from "CSI" creators Anthony Zuiker, Carol Mendelsohn, and Ann Donahue and averages a decent 8.5 million total viewers.

Entertainment Weekly describes the departure of "CSI" as "the end of an era," adding that the series "ushered in a wave of gritty procedural crime dramas using technology-based murder-solving methods with an ensemble cast." The show, which debuted successfully in 2000, gave way for several spin-offs such as "CSI: Miami," "CSI: New York," and the recently launched "CSI: Cyber."

According to the news outlet, "the flagship series helped give CBS its programming brand for the 21st century," with the network's other franchises such as "NCIS" and "Criminal Minds" bearing success because of "CSI." This also effectively labeled CBS as "a network for crime dramas," Entertainment Weekly added.

Season 15's finale saw the departure of Nick Stokes (George Eads) from the team after getting a job offer to head up his own San Diego-based lab, Zap2it reported. Speaking about the actor's exit, showrunner Don McGill said in a February 2015 interview that the character reached the peak of its evolution.

"I hope fans will embrace what we embrace -- which is the evolution of the Nick Stokes character from Season 1 through Season 15 now," McGill told Zap2it. "We first met Nick as a young CSI who was clearly being mentored by [Gil] Grissom. With Grissom leaving, Nick in many ways inherited the role of Grissom -- not just in his forensic expertise but just kind of in his role as heart and soul of the team."

The finale also tackled the conclusion of the Gig Harbor Killer case, the news outlet wrote. McGill described the last episode as a "pretty great" end to the serial killer twins Jared Briscoe and Paul Winthrop, who were portrayed by Mark-Paul Gosselaar. However, the finale was also a huge and emotional goodbye for Nick and Eads.

"I think there [was] a really great emotional kind of tear jerker ending, even as we have a little bit of a cliffhanger going. I hope people will really embrace the duality of that finale," McGill told Zap2it.
