Steve Thunderson is a minor character in killer7. He is a Democratic Party congressman who is murdered by The Handsome Men for unknown reasons, although Christopher Mills' explanation of how the HANDSOMEMAN comic storylines subsequently occur in the real world suggests his death was part of a recent plot. His death motivates the U.S. Government to dispatch the Smith Syndicate to the Dominican Republic in order to hunt down Trevor Pearlharbor. It is not known which state Thunderson represents.
As shown in the source code, Steve Thunderson was originally a target in the "Temple of Horizon" stage (see text file "ST12Font"). Here, he's described as "a top echelon of the Democratic Party." It is possible that he had worked with Curtis Blackburn at the Horizon company. Although the Handsome Men don't seem to have a connection to the Horizon plotline, in the final game they were made to combat the Heaven Smile, the production of which is linked to Curtis and Horizon.
