The most anticipated finale episode of the CBS crime drama "CSI: Crime Scene Investigation" will take its viewers through the worst roller-coaster of events.

Along with the return of Eric Roberts as Brother Daniel Larson, the popular series will also focus on Gig Harbor Killer in its last episode of season 15.

Meanwhile, several speculations are doing the rounds that two main characters of "CSI" may become victim of the Gig Harbor Killer in episode 18 titled "End Game". While one of the them will be making an exit from the show, the fortune of the other is yet to be revealed.

As per the reports by TV Guide, the cast member to be killed in the finale of the crime drama will be someone who was part of the series since season 1.

However, the report stated that it is not George Eads' character Nicholas "Nick" Stokes who will be in question since there is a possibility for him to return to the show.

So it could either be Greg Sanders (Eric Szmanda), Dr Albert "Al" Robbins (Robert David Hall), Sara Sidle (Jorja Fox) or Dr David Phillips (David Berman) (nicknamed "Super Dave") who will bid goodbye to the CBS drama.

Meanwhile "CSI" is scheduled to return onscreen with its mid-season premiere episode titled "Merchants Of Menace" on Sunday, 25 January, at 10:30pm.
