As we learned earlier this week, William Peterson's Gil Grissom will be leaving CSI 10 episodes into this season.
Today, CBS entertainment president Nina Tassler spoke a little bit about the description of the character who will replace him (who has not yet been cast):
From TV Guide:
"He's a doctor and scientist who comes into the CSI as an outsider; he won't start off as the boss. Here's the catch: He's a bit of a DNA expert, and has identified a common profile among serial killers - in his own genes!"
Sounds like it could be an interesting twist for the series, no?
