A pair of teenager girls race down the street as they play an interactive video game. One of them trips on a duffel bag sitting in front of a church. Curious, they unzip it, only to discover a small human hand. Later, Benson and Fin survey the crime scene. Fin tells Benson that the victim has to be Marnie, a little girl who had been reported missing the prior day. Warner can't pinpoint the time of death because of the cold weather. Benson compares a photo of little Marnie to the dead girl. Sadly, it's a match. Fin stops Marnie's hysterical mother, Susan, from approaching the body. Benson watches, there's nothing anyone can do for her.
