When Benson experiences flashbacks to the kidnapping case 13 years earlier, the director, Jean de Segonzac opted against using make-up and clothing to make Hargitay look younger. Instead, he decided to use an experimental technique of merging the episode's scenes with footage from the show's first season to make it seem like Benson was having flashbacks to the case, which never actually occured in a previous episode.
The flash back scene in the beginning of the episode with Detective Benson is from season one's Bad Blood (2000)
This is the 300th episode of the series.
EP, Dick Wolf refers to the disappearance of Etan Patz (first missing child to appear on milk cartons) as an inspiration for this episode.
The flashback scene of Det. Munch watching videotapes is taken from Season 1, Episode 21 Nocturne (2000).
