WHEN A PARASOMNIAC IS FOUND OVER THE BODY OF A DEAD WOMAN, THE CSIs INVESTIGATE WHETHER THEY HAVE A CLOSED CASE OR IF THERE'S MORE TO IT THAN MEETS THE EYE, ON "CSI: NY," WEDNESDAY, DEC. 15

"Night, Mother" -- When a parasomniac sleep walks out of her apartment complex and is later found covered in blood next to a woman's body, the CSIs must investigate if they have a closed case or if there's more to it than meets the eye, on CSI: NY, Wednesday, Dec. 15 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Deran Serafian directed the episode written by Janet Tamaro.

Even though their suspect is covered in the victim's blood and has a wooden stake thought to be the murder weapon at her side, Mac thinks there is more to the case than what they see. Meanwhile, Danny and Aiden investigate the murder of a "professional" pickpocket who was beaten to death.
