Prior to the Korean occupation, Simpson was the Warden of Riverside Penitentiary who abused his station. Among them was torturing and sexually abusing his prisoners, including future Resistance member Dana Moore.
After the North Korean invasion, Simpson felt that there was no hope to repel the North Koreans so he decided to collaborate to best insure the welfare of his people.
In 2029, Simpson had the well known Benjamin Walker under his custody. He had Walker broken into submission and used him as a trap for the Resistance after requesting the aid of his fellow collaborator and double agent James Crawford. However, the key members of the Resistance managed to escape despite the KPA launching a coordinated strike on Resistance strongholds in Philadelphia.
The Resistance retaliated by launching an uprising in the city's prison area and managed to infiltrate Independence Hall and taking Simpson hostage on live television. Simpson pleaded with Jack Parrish that the Resistance's rebellion would forced the KPA to kill every American in the city with nerve gas in which they had done this before with Boston and Pittsburgh, that the public and the Resistance weren't aware of. But Simpson was stabbed in the throat by a vengeful Dana before he can reveal the KPA's plan of gassing the city, which eventually came in fruition.
During the events of Aftermath, Benjamin Walker can be heard reading a KPA sponsored speech in which he labels Mayor Simpson as heading a corrupt regime; this shows that the KPA have since disavowed the actions of Mayor Simpson and now use him as an example of the corruption of American leadership.
