After shutting the campus down, Gideon, Hotch and the BAU team create a detailed profile of their UnSub, but when the killings on campus continue after they take a suspect into custody, the team begins to doubt themselves.
The original version of this episode was originally supposed to air as episode 2x21 in April of 2007. This was around the time of the Virginia Tech shootings, so the episode was shelved, due to possible sensitivity of the campus murders storyline.
The episode was edited from its original form in season 2 to incorporate Mandy Patinkin's departure into the storyline.
