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

DENVER – United States Attorney Jason R. Dunn announced today that Jeffrey Mons Olson, age 49, of Aurora, Colorado, pleaded guilty today before U.S. District Court Judge Raymond P. Moore to being a felon in possession of a firearm.  Olson appeared at the hearing in custody and was remanded at its conclusion.  He is scheduled to be sentenced by Judge Moore on March 19, 2020. 

According to the stipulated facts contained in the plea agreement, on March 28, 2019, the Colorado Department of Adult Parole conducted surveillance on Olson.  During the surveillance, parole officers observed the defendant at a storage locker in Aurora.  They then followed him home.  Once at home, parole officers searched Olson’s Dodge Ram truck.  They located a loaded Glock between the driver’s seat and the center console.  Also discovered behind the driver’s seat was a black duffle bag with four additional firearms.  Four of the five firearms recovered in the truck were loaded and previously reported stolen. 

On March 29, 2019, investigators with the Denver Police Department and Homeland Security Investigations (HSI) went to the storage locker in Aurora, which had been rented by the defendant’s girlfriend.  Law enforcement obtained and executed a search warrant at the locker.  Inside the storage unit agents and officers found and seized nine additional firearms, including two semi-automatic rifles and seven handguns.  Four of these firearms were loaded.  In addition to the weapons, assorted ammunition of various calibers were seized.  Prior to possessing the firearms and ammunition, Olson had been previously convicted of at least one felony.

“A felon carrying loaded firearms is a danger to the community,” said U.S. Attorney Jason Dunn.  “Thanks to the hard work of this office and local and federal law enforcement, he was arrested, has admitted to his crime, and will face his punishment.”

Olson was indicted by a federal grand jury in Denver on September 5, 2019.  He pleaded guilty today, December 23, 2019.  The statutory maximum penalty for being a felon in possession of a firearm is not more than 10 years in federal prison, and up to a $250,000 fine.  This case was investigated by HSI, the Colorado Department of Adult Parole and the Denver Police Department.  The defendant is being prosecuted by Assistant U.S. Attorney Conor Flanigan.
