Just like on "The Closer", this is a "Flynn & Provenza" episode.
The actor portraying the victim in this episode, Mat Devine, is the frontman for a band called "Kill Hannah". He sings a snippet of one of his band's songs, Promise Me, from their album Wake Up the Sleepers, albeit horribly.
Lee Garlington (Mrs. Sloan) was also in "Sneakers"... where Mary McDonald was an integral character > both actors delivered great moments, tho not together
Jeanette Brox, who portrays Dana Sloan, shared an ER episode with Mary McDonnell, who was portraying Carter's mother, Eleanor Carter visiting his workplace in Damage Is Done (2002).
