This concept came to me while on shift work in Tampa. It starts out with a CEO of a major pharmaceutical and medical supply company (Meditech Industries...just made this up on the spot) who is spirals slowly into depression over the murder of his wife and child. As money usually makes the world go round, his attempts at getting the best investigation (funding police activities out of pocket) team, lawyers, specialists, resulted in zero gain due to a technicality. He lost all faith in the justice system. Jared Mercer takes his fortune and calls it quits, selling off his shares. He cuts all ties with society for several years.
Judge - Bryce Stefansson. Circuit court judge presiding over a low-profile murder case. All indications look as though the defendant is on the path to accquital, much to his dismay. He's privvy to information that clearly points the defendant as guilty. Years on the bench has made him witness to the guilty walking and the innocent caged. It's the last straw for Bryce. Prior to reconvening, Judge Stefansson secrets a hangun under his bench. He's made his decision and the outcome will be based of the verdict handed down by the jury. The defendant is found not guilty. Bryce pulls the gun and kills the man. He is later found guilty of first-degree murder and sentenced to death by the electric chair. Bryce does not appeal the decision.
Jury - Manford Smith suffers from multiple personality disorder (MPD). At a young age, he suffered physical abuse by the hands of family and strangers alike. Something about him triggered violent reactions. He's rarely known a single day of affection. As a result, his mind has fractured as a coping mechanism. The strange twist is that all his personalities suffer dsyfunction of one sort or another and are all predisposed to violent tendancies. From his perspective, he see others scheming to hurt...and so he one-ups society by striking first and has become known as "Hydra" among the media. He is also one of the most-wanted men in US history having killed dozens in gruesome fashions. As a serial killer, Manford is careful to leave a calling card, but his modus operandi changes each time. The victims are never slain the same way twice, earning him his nickname. Investigations lead authorities to believe this was a cult in action, but only one set of prints were ever found at the scenes. A profiler suggested the killer might have MPD, hence the nickname given. Months later, he is caught and found mentally unfit to stand trial. He is sentenced to a mental hospital.
Executioner - Jerome Shields had worked timber for as long as he could hold an axe. He would travel the Pacific Northwest taking jobs, supporting a wife and three kids in Georgia. He would visit on occasion or have them visit him whenever there was a break in work. He took a job in Oregon working under the heel of a racist foreman (later to be found out that he had ties to the white supremicists). Jerome was never one prone to violence, but during a visit early in his work, the foreman made threats against his family, working him extra hours for no pay. Jerome persisted despite the negative environment. All others either turned a deaf ear for fear of reprisal. Weeks of unrelenting bigotry made Jerome snap, the straw being a phone call from his wife that their kids were approached by strangers, his eldest son being hospitalized. Jerome drew the conclusion that the foreman was responsible, having contacted connections in Georgia to terrorize his family for nothing more than sport. When police arrived, they were unable to identify the foreman. Due to the vicious nature of the murder, Jerome Shields was put on death row.
In enters Jared. For the years he was abroad, he whispered in the ears of very influential members of various countries, corporations...all members of an underground society. Jared put forth a project to make a worldly justice system...one that's flawless, seeks out impiracal evidence to substantiate the target's guilt or innocence. The pilot program is to be run under his direction within US territories. Gathering some of the top geneticists, scientists and physicists, he puts a team together to create the ultimate unit together, comprised of three members - Judge, Jury and Executioner. Only thing missing are candidates. After exhaustive efforts, Bryce, Manford and Jerome are selected. They are whisked away to a secret location (details on how will be covered later). Here, they undergo a physical and psychological transformations tailored to the task at hand...hunt down and prosecute some of the most violent and manipulative criminals that often find themselves out of reach from Justice's grasp.
