Scott Jackson is one of the demonic spirits that haunts Bobby Mackey's Music World. He and Alonzo Walling beheaded Jackson's girlfriend, Pearl Bryan. It is believed they sacrificed it as part of a Satanic ritual. They were tracked down at the current location of where Bobby Mackey's currently sits. The two men proclaimed at the gallows that they would come back to haunt the area forever.
It is possible that Jackson was the spirit that Ritch Lawson encountered in the restroom at Bobby Mackey's as he was described as having a "handle-bar mustache".
