Stanley hated carpools. He believed they were obvious symbols of modern traffic which made him feel downright claustrophobic. Stanley loved American horror films such as The Hitcher and The Texas Chainsaw Massacre and started to contemplate the 'dark wisdom' of exploring copycat crimes (as some odd malicious gesture meant to signify his dissatisfaction with modern civilization behaviours).
Stanley came up with a very strange and ominous plan. He worked for an average American insurance company as a file-clerk in Chicago. His work was consistent and no one really bothered him; he also lived alone and watched a lot of television into the late hours of the night. Stanley decided to form a carpool system through a series of classified ads. He wanted to establish a rotation-routine by which various members of the carpool club would take turns being the driver and selecting which members were part of a given week's carpool. The rotation system Stanley successfully set up enabled members to join and leave the club at any time. Stanley intended to use this established club to create a ring of murder.
Stanley was a big fan of American comic books, and he was obsessed with the comic book super-villain Doctor Octopus (Marvel Comics) who made him feel better about modern civilization's seeming preoccupation with multi-tasking totems (i.e., smartphones, shopping malls, etc.). Stanley decided that his grudge with carpools would effectively make him like Doctor Octopus, once his plan started to come to fruition. He would be the ultimate road terror, grabbing hapless victims like a precise octopus.
Stanley befriended members of the carpool club and invited them to his apartment for drinks on weekends. He would poison their drinks and then burn their bodies in the heating furnace which was located in the basement of his apartment building. When the members were conspicuously absent from their carpool rounds, they were simply replaced by newly-enlisted members in the rotation system.
After about a dozen of such murders, police started to become more and more interrogative. A young detective working for the Chicago Police Department named Jim Smart realized that the dozen or so deaths and disappearances involved people who were part of Stanley's carpool club which was found in the Chicago classifieds section of the newspaper. At first, Detective Smart did not suspect Stanley had anything to do with these crimes but wondered why all the deaths and disappearances involved members of this carpool club. However, as Detective Smart discovered that there were only a handful of constant members of the club besides the founder Stanley, he began to suspect that Stanley was the mastermind of this predetermined operation. Detective Smart wondered why someone would want to use a carpool club to select victims.
Detective Smart decided to go undercover and enlist himself as a member of Stanley's carpool club. He soon became a regular member and was eventually invited for weekend drinks at Stanley's apartment on a special poker-night which included three members besides himself and Stanley. At the poker-party, Smart asked Stanley why people from the club were disappearing off the face of the earth, and one of the members joked that it was because they wanted to get away from Stanley, the founder. Smart observed that Stanley gave a wry smile at this joke and became suspicious.
Smart decided to take Stanley on a mini-drive the next weekend. They were driving up to a national park and during the drive (Smart was driving), Smart asked Stanley what he thought about general cynicism towards American roads, highways, and traffic. Stanley told him that he was not fond of traffic but was an admirer of the American road system. Smart then told Stanley that he was considering why a psychopath might want to kill off members of a carpool club and then subtly joked to Stanley that it would be ironic if a carpool club founder (like Stanley) turned out to be the mastermind of a carpool member killing spree. Stanley suddenly freaked out and grabbed Smart's steering wheel and turned it, and their car veered off the road.
The accident was serious and Smart broke his leg. Stanley was paralyzed from the neck down and had prosthetics-insertion surgery performed on his body. Stanley received an entire prosthetics system, which enabled him to move around with special mechanical braces attached to the bones of his arms and legs. During his rehabilitation, Stanley wrote in his journal that he was finally Doctor Octopus.
