When Detective Brisco and Detective Green examine the victim's apartment, they come across a Playbill program and ticket for the opera La Boheme. Briscoe is derisive, but Green tells him that "You don't have to love opera to love La Boheme. It's a Broadway play, bro." Detective Green is played by Jesse L. Martin who was an original cast member of the Broadway play Rent, which is based on La Boheme. (The play Rent was adapted into Rent (2005).)
