THE BLUE PAINT SERIAL KILLER RETURNS AND THE CSI GRAVEYARD SHIFT MUST USE ALL OF THEIR RESOURCES TO SOLVE THE MURDERS OF FOUR FEMALE COLLEGE STUDENTS, ON "CSI: CRIME SCENE INVESTIGATION," THURSDAY, NOV. 4

Aisha Tyler ("Friends") Guest Stars

"What's Eating Gilbert Grissom" -- Grissom is haunted by the return of the blue paint serial killer that got away two years ago, on CSI: CRIME SCENE INVESTIGATION, Thursday, Nov. 4 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Ken Fink directed the episode written by Sarah Goldfinger.

Aisha Tyler ("Friends") guest stars as the new DNA lab technician.

As the CSI team investigates the multiple murders on the WLVU college campus, they realize that the murders took place on the two-year anniversary of the execution of John Mathers, a man found guilty of murdering a woman in the same manner as these new victims at this college campus. The main clue tying four murders together is the blue paint found on all the victims' hands. The killer fooled the CSI team two years ago, when another murder took place the night of John Mathers' execution, and Grissom and team are determined to not let that happen again.
