"The Brain Surgeon" Investigation was a minor police investigation that occured in the final season of DEXTER. It was a Miami Metro Homicide investigation into a Serial Killer known as "The Brain Surgeon", and there were only two identified victims prior to when the killer's identity was revealed (both of which had their craniums sawn into and a portion of their brains removed). Lyle Sussman was the initial and primary suspect in this investigation, though, unbeknownst to the police, the true killer had used Sussman as a patsy and later murdered him himself, staging Sussman's death as a suicide in order to avoid further investigation from the police. After this, the case was officially closed and had received no mention for a long while (the police believed that Sussman was "The Brain Surgeon" and thought he had commited suicide out of remorse). However, the true "Brain Surgeon" still lived on and continued to kill more people (these victims were not left out in the public like Robert Bailey) and he eventually victimized his own mother, Evelyn Vogel, though this murder did not link the killer to his previous murders because he didn't cut into her skull. The police did bring Oliver Saxon (who was the true "Brain Surgeon") in to be questioned about Cassie Jollenston's murder, as they thought of him as a potential suspect. However, they decided to let him loose after falling for his lies. However, once Dexter requested the recordings of Saxon killing his victims to be broadcasted on the news, Saxon's face was publicly exposed and Miami Metro proved his guilt. The investigation then came to a permanent end when Dexter Morgan stabbed a pen into Oliver's neck in a jail cell, which ended Oliver's life...However, Dexter was able to convince Miami Metro that it was just an act of self-defense. This was 'proven' by the police footage, which showed Oliver attempting to kill Dexter first.
