Family members of murder victims (Widmer, Rath and Silvio) are in a support group where they discuss their feelings about the loss they have each suffered. Short-handed, Gee investigates the Widmer homicide at the Waterfront Bar. Bayliss' homicide is unidentified for 48 hours before she is identified as being Rath. Lewis and Munch investigate a car jacking at Federal Hill, where the mother is the victim and the 3-year-old daughter in the car at the time is missing. Meanwhile, Howard, Kellerman and Pembleton stay behind. Frank interviews the two witnesses that Tim had in for questioning and gets a lead on a suspect. Cox joins the support group meeting late; she is still coping with the death of her father.
