Joe Novelli brings in a K-9 unit which tracks the missing teenager to a house in the neighborhood. The house is owned by Stan Shawl and his wife Margaret. Jessica's discovered, still alive, taped up in the bottom of a closet. When confronted with the girl's abduction, Shawl claims that it wasn't him but his twin brother, Ed.
