Name: Stephen Dragomir
Concept: Death Row Inmate
Appearance: Balding middle age man, though with a barrel chest, about 5'9". Surprisingly strong, I suspect- not much to do in that cell but work out until you pass out.
Personality: <Thousand Yard Stare>. At least at first. He was pretty amiable and outgoing before he got stuck in an isolation cell, so with a little engagement that'll come out. He's also pretty creative and cunning, so even if no one really tries to talk to him, he'll still be doing stuff. Often underestimated.
Fourteen murders with the same M.O. Fourteen that they know about. How many more bodies are there out there?
In the end, they got Dragomir for a murder that wasn't part of the pattern. While he was kidnapping his last victim- well, they think she was going to be his last victim- a security guard came across him while he was hustling her out of the loading dock of her dorm. He gutted him like a fish, but couldn't stay behind to clean up after himself. That and the campus police managed to get a call out to the local P.D., and he was driven off the road outside of town. So, they got him for one body- and because of how things went, they could never even introduce the others as pattern evidence, at least implicate, in a court of law, that he was a cold, calculating killer. Still, the prison got the message from the cops- this wasn't just any death row inmate. They've treated him with the Supermax precautions from day one, which tends to drive even the sane a little batty. Start with a crazy man... well. They get crazier. Especially after 15 years of life on death row. (He should be dead by now, except that the last couple of governors haven't been willing to sign death warrants.)
In terms of the killings they're pretty sure he did (Well, they stopped after he was arrested, right?), he targeted college coeds that he seems to have considered troublemakers. Not just sexually- there were plenty of sexually promiscuous coeds that he didn't drag back to his place, and some even went back to his apartment for almost normal sex- but usually were involved in something more than just sexual peccadillos. Prostitution. Drug Dealing. Abortion. Peer pressure that convinced other girls to engage in depraved acts. His most famous victim was the rush chair from a prestigious sorority who delighted in violating her pledges with a broomstick. Both the extra effort he put into her and the fact she was a famous lawyer's daughter is what turned the press onto the story. The police managed to keep the girl's problems quiet, mostly to see if they could sort out the real tips from the false ones.
The M.O for the killings was basically the same- kidnap the girl, drive her to an unknown location- to this day, the police haven't found his torture site- where he'd keep her for a few days. Repeated rape- perhaps with a partner, sometimes with objects- burning with heated metal objects as the primary means of torture, though brute physical force was used sometimes in order to get the girl in restraints. Death came by bastinato- the repeated beating of the soles of the feet, which caused both extreme pain and a lengthy death. After his victim died, he brought the body to the West Forest, suspended it over a branch by the ankles, and slit its throat to drain it of blood. (The torture chamber had to be pretty close to the woods, since the bodies were mutilated before lividity set in). Then, Dragomir removed the fingers and feet with a meat cleaver, gouged out the eyes, and doused the faces in sulfuric acid. Still, no one's sure if they've found all the bodies- Dragomir steadfastly maintains his innocence- or why he did it. He just refused to talk about anything after his arrest.
So, to sum up: Stephen Dragomir is a sick bastard who should be shot. No one's done it up to this point, and it may be too late now....
(Does this fit the bill for evil, or were you looking for something else? If we want to get him involved, I think we can stipulate that he was out of his cell for some reason- maybe headed to the infirmary for a checkup or something.)
