Sweet Jane

Catherine investigates the murder of a runaway teen whose naked body is found in a desert lot behind a hotel. Helping with the case is Mike Keppler (played by Liev Schreiber), an experienced CSI from Baltimore who is the newest hire on the day shift but is filling in temporarily on the night shift since Grissom is on sabbatical. Their investigation reveals the dead girl may be the victim of a serial killer whose slayings may go back decades.
