Scott Harbin

Scott Harbin was a suspect of being the Keystone Killer.

History
Not much is revealed about Scott's early days, other than that he appeared to have done military service at some point. In the 1980s, he was an alarm installer in Philadelphia who moonlighted as a fetish burglar, frequently breaking into peoples' homes at night and stealing female underwear. He was considered a suspect for being the Keystone Killer, even being interviewed by profiler Max Ryan, who didn't consider him a valid suspect. At some point, he worked with Walter Kern, the real Keystone Killer. In 1988, the year Kern stopped killing due to being in a car accident, Scott killed a man during a routine break-in and was arrested and sentenced to jail. In 2006, when Walter resumed killing, Scott was released on parole. In one of Kern's word-search puzzles, the word "NIBRAS", "S. Harbin" backwards, was found. That, coupled with the fact that Scott had already violated his parole, led the BAU to consider him a suspect, despite Ryan's strong objections, and raid his home along with a SWAT team. While searching through his home, they discovered that Scott had abducted a woman, presumably with the intention to rape her, and arrested him. Outside his home, another letter from Kern was found, clearing Scott from any suspicions of being the Keystone Killer.
