Audubon County Man Sentenced for a Firearm Offense

For Immediate Release
U.S. Attorney's Office, Southern District of Iowa

COUNCIL BLUFFS, IA – An Audubon County man was sentenced on April 18, 2023, to 60 months in prison following his plea of guilty to being a prohibited person in possession of a firearm.

On September 15, 2022, Audubon County Sheriff’s Department, Atlantic Police Department, Audubon Police Department, Cass County Sheriff’s Department, and Iowa State Patrol, responded to a call of shots fired. Deputies found Adam Lee Karstens, 41, standing outside the residence by a locked pickup truck. A search of the vehicle revealed a nine-millimeter Taurus handgun with an obliterated serial number underneath the driver’s seat. Karstens was prohibited from possessing a firearm because he had a prior felony conviction. Karstens must serve a three-year term of supervised release after the prison term. There is no parole in the federal system.

United States Attorney Richard D. Westphal of the Southern District of Iowa made the announcement. The Audubon County Sheriff’s Office and the Iowa Division of Narcotics Enforcement investigated the case.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. In May 2021, the Department of Justice launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
