THE CSI TEAM INVESTIGATES THE MYSTERIOUS DEATHS OF IDENTICAL TWINS KILLED ON THE VERY SAME NIGHT, ON A REBROADCAST OF "CSI: CRIME SCENE INVESTIGATION," THURSDAY, JAN. 3

"Happenstance" - When identical twins are found dead on the same night, the CSI team investigates whether or not the two murders are connected, on a rebroadcast of CSI: CRIME SCENE INVESTIGATION, Thursday, Jan. 3 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Jean de Segonzac directed the episode from a script by Sarah Goldfinger. (Originally broadcast 11/16/06)

The evidence in both cases does not immediately prove a connection between the two deaths. However, as the CSIs dig deeper into the histories of the women, a surprising twist takes the investigation in a new direction.
