Cal Rooney[1][2] is a character in DEXTER. He is a carnival worker who is Dexter's first victim shown in Season 3. He is only shown briefly in flashbacks while Dexter recounts in his usual ambiguous way what he did over the summer to his dentist. Dexter is shown injecting the man, who appears to be in his early 50's, with tranquilizer, taking a blood sample from his cheek, and striking him with a meat cleaver.
