became a serial killer known as the "Brain Surgeon"; he removed the anterior insular cortex (the part of the brain that controls empathy) from his victims' brains and left them on his mother's doorstep. Vogel asks Dexter to help her track the Brain Surgeon down, unaware of his identity. Dexter unknowingly meets him when Saxon begins dating Dexter's neighbor, Cassie Jolleston. After Saxon murders Jolleston and Dexter's apprentice Zach Hamilton, he realizes his identity. Saxon and Dr. Vogel reunite, but Vogel eventually decides to let Dexter kill him after seeing a videotape of Saxon murdering one of her patients. Saxon, aware of the plot, slits Vogel's throat, killing her in front of Dexter. Dexter later tracks him down and ties him to a makeshift kill table, but chooses to let Deb hand him over to the police. However, Saxon is freed by a marshall and shoots Deb. Saxon is later killed by Dexter with a pen to his carotid artery in a jail interrogation room.
