Colorado Man Pleads Guilty to a Firearm Offense

CONCORD - A Louisville, Colorado man pleaded guilty today in federal court in Concord to a firearm offense, U.S. Attorney Jane E. Young announces.

Shelby Theriault, 30, pleaded guilty to one count of possession of an unregistered firearm. U.S. District Court Steven McAuliffe scheduled sentencing for December 18, 2024.

On January 20, 2024, Theriault was arrested for unrelated theft offenses and found to be in possession of a sawed-off shotgun. Theriault subsequently admitted to stealing the shotgun from a residence in New Hampshire and sawing down the barrel thereafter. Theriault then did not register the sawed-off shotgun as required by the National Firearm Act.

The charging statute provides a sentence of no greater than 10 years in prison, 3 years of supervised release, and a fine of $10,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

The Bureau of Alcohol, Tobacco, Firearms, and Explosives and the Conway Police Department led the investigation. Assistant U.S. Attorney Tiffany Scanlon is prosecuting 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. On May 26, 2021, the department 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.
