The article "Suspect Found in School Teacher Murder Case" is shown to be written by Kevin Egeland of the Miami Tribune. An advertisement for Egeland Motors can be seen on the bottom right corner of the newspaper's webpage. In actuality, Kevin Egeland is the graphic artist who worked on this episode of Dexter.
This episode was filmed in early October 2008, by which time the actors playing Dexter and Deb were dating in real life. They then eloped and got married on Dec 31 2008. So in the scene where Deb is advising Dex on which wedding ring to give to Rita, Jennifer Carpenter was literally picking out the one she herself received a few months later.
