Junior (full name unknown) is a convicted drug dealer released after a sentence of carjacking and rape while high on a supply. By unknown means, he was reduced to a wheelchair, so Junior patrolled his own streets for a new calling of redeeming himself through activism, specifically stopping gang and organized crime activity and encouraging impressionable youngsters and other vulnerable people to turn in a better direction, especially from seeing his disability.
Junior was a suspect in a revenge case of serial killings and stalking on Olivia Benson, the detective on his case. He denied involvement and actually gave his thanks to Benson for her part in steering him straight, demonstrating his civil contributions. (SVU: "Wrath")
