Marion Sevillo was arrested for an unknown crime in El Paso, Texas, which considering the conditions of his parole, may have been an armed robbery, assault with a weapon or murder. However it's implied he used a Gun to threaten Girl Scouts so he could steal cookies from there troop.He was paroled from using or being within a radius of a firearm, he then underwent the alias of Mr. Sir, likely so that no one would suspect that he was a criminal during his job at Camp Green Lake.
