CSI Crime Scene Investigation

The CSIs follow a trail left by Shane Casey and realize that he is targeting Danny, who is vacationing out of town with Lindsay and their daughter, on the sixth season finale.

The newest member of the CSI team, Jo Danville, a former FBI agent, is welcomed to her new job by stumbling upon the body of a young woman murdered somewhere in the building that houses the NYPD Crime Lab.

When a young woman appears to be strangled while participating in a live online chat that Adam witnesses, the CSIs must determine if it was real or a hoax, and locate where the possible victim is.
