Sussman was a hunter who was kidnapped by Oliver Saxon(though at this point, Saxon's identity wasn't known) and forced to kill a man named Leonard Welks by putting a bag over the latter's head while he was restrained, causing him to suffocate to death. All the while, Saxon was holding a gun on Sussman and shot him in the back of the head at close range (as revealed by the DVD he leaves for Evelyn Vogel in her house). Sussman was later found dead at his cabin by Dexter Morgan, having been impaled on a meat hook through the back of his skull. Knowing that the police would come to investigate, Saxon had later restaged the scene in order to make it appear as a suicide, and to convince the authorities that Sussman was The Brain Surgeon. This false evidence resulted in them closing The Brain Surgeon Case. Sussman's head was then blown to smithereens with a shotgun, making his occipital lobes accessible (the portion of the brain that's responsible for vision), which were removed and sent to Dr. Vogelin packages.
