Schroeder sold hundreds of firearms at gun shows in Wisconsin and other states, and displayed signs at shows advertising that he did not collect taxes on his sales or conduct background checks on customers, according to the indictment.
Schroeder made more than $100,000 selling the weapons, the indictment claimed.
During the investigation, Bureau of Alcohol, Tobacco, Firearms and Explosives executed a search warrant at Schroeder's home. They seized:
Over 200 handwritten receipts documenting sales to 200 customers
Records showing gun sales revenue of more than $100,000
Sales records for approximately 20 out-of-state customers
Approximately 1,000 business cards advertising "Gary Schroeder: Buy and Sell Guns"
Dozens of ATF forms 4473 bearing Schroeder’s signature immediately below a sentence that reads, “I further understand that the repetitive purchase of firearms for the purpose of resale for livelihood and profit without a Federal firearms license is a violation of Federal law.”
A number of firearms sold by Schroeder were later involved in separate crimes, court documents said.
If convicted, Schroeder faces a maximum of five years in prison and $250,000 fine.
