This episode marks the final time in which the entire Stabler family appear together in the same episode. The four children would appear together in the episode Pretend (2007), but without Kathy Stabler (Isabel Gillies) present.
This is episode may partially be based on former Canadian bank robber Edwin Alonzo Boyd, who also confessed to a murder shortly before dying.
Besides the obvious fact that this episode aired out of sequence based on Mariska's shorter hair, she is also still pregnant.
This episode was recorded during season 7 sometime. You can tell by Mariska Hargitay's shorter hairstyle.
