Hamilton Bartholomew

Hamilton Bartholomew, a.k.a. "The Piano Man", was a serial rapist and murderer who appeared in Unknown Subject.

History
Almost nothing about Bartholomew's personal life is revealed, other than that he was married and worked as a lounge piano player at a bar. In 2007, he started raping women, starting with Regina Lampert, whom he had seen pick up several men at the bar. Over the next five years, he raped an additional 11 women.

Modus Operandi
The Piano Man targeted women of different races and social classes; what they had in common was that they were all smokers. After stalking them for some time, he would abduct them from near some kind of public venue such as a restaurant or a mall, drugging them with cigarettes laced with some drug that mimics a date rape drug, binding them with piano wire (hence his nickname) and raping them. During the rapes, he would play a piano ballet on some media player, so whenever they heard the song again afterwards they would relive the trauma. As forensic countermeasures, he wore a mask to conceal his identity and wore gloves to avoid leaving behind fingerprints.
