A federal jury in Cedar Rapids has convicted Austin Andrew Goodman, 42, of Dubuque, of one count of possession of a firearm by a prohibited person.

The verdict followed a one-day trial in the U.S. District Court for the Northern District of Iowa. Goodman was charged under 18 U.S.C. §§ 922(g)(4) and 924(a)(8) for knowingly possessing a firearm after having been committed to a mental institution.

According to evidence presented at trial and federal court records, the offense occurred on March 3, 2025. Goodman entered the Historic Federal Building at 350 West 6th Street in Dubuque, the location of the city council chambers, while a council meeting was in progress. He was dressed in a suit with an American flag draped over his shoulders and tape covering his mouth. He carried a loaded firearm in a holster on his hip and held two dogs on leashes. He livestreamed his approach to the chambers on Facebook.

Dubuque police officers, who provide security for council meetings, stopped him near the chambers. Officers recovered a loaded semiautomatic handgun from his person. State charges arising from the same incident were later dismissed after federal authorities assumed prosecution.

A grand jury returned the federal indictment in September 2025 under case number 2:25-cr-01039. The court denied Goodman’s pretrial motions to dismiss the indictment and to suppress evidence. The jury returned its guilty verdict this week.

No sentencing date has been set. The offense carries a maximum penalty of 15 years in prison, a $250,000 fine, and up to three years of supervised release. Federal sentences do not include parole.
