Newton County man indicted for illegally possessing firearms

SPRINGFIELD, Mo. – A Diamond, Mo., man was indicted by a federal grand jury this week for illegally possessing firearms after a prior felony conviction.

Jason A. Duncan, 40, was charged with three counts of being a felon in possession of firearms, by a federal grand jury in Springfield, Mo. The indictment, which replaces a complaint filed on June 3, 2025, alleges that Duncan possessed a Palmetto State Armory rifle and a Taurus pistol on Aug. 19, 2024, a Hi-Point pistol on Oct. 3, 2024, and Glock pistol on Jan. 23, 2025. Duncan has prior felony convictions and is prohibited from possessing a firearm under federal law.

The charges contained in this indictment are simply accusations, and not evidence of guilt. Evidence supporting the charges must be presented to a federal trial jury, whose duty is to determine guilt or innocence.

This case is being prosecuted by Assistant U.S. Attorney Stephanie L. Wan. It was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives; the Federal Bureau of Investigation; and the Joplin, Seneca, and Springfield, Mo., Police Departments.
