Man Arrested With Assault Rifle and Ammo Outside Oswego Walmart

A Pennsylvania man is being held on weapons charges Wednesday morning after Oswego police stopped him in the parking lot of the Route 34 Walmart with an AR-15 assault rifle, 12-gauge shotgun and ammunition.

Oswego Police responded to Walmart at about 8:07 p.m. Tuesday for a report of a man with a weapon in his vehicle. Upon arrival, police met with a witness and were informed that Mason K. Dunne, 21, of Pennsylvania, allegedly had an AR-15 assault rifle in car.

Police located the vehicle in the parking lot and found Dunne in the car. Dunne was removed from the vehicle without incident and during a search of the vehicle the AR-15, 12-gauge shotgun and ammunition were located.

Captain Jeff Burgner said they had not counted the ammunition yet, but there was a "significant amount" found. 

During the course of the investigation it was determined the weapons allegedly had been reported stolen during a burglary in Upper Allen Township Pennsylvania, said Oswego Police. It was also determined that Oswego was simply a stop during Dunne's travels to another state and there was no indication that there was a plan to cause violence in Oswego.

Police also determined that Dunne had a no bond warrant for his arrest out of Pennsylvania for possession of a stolen firearm.

Dunne was charged with one count of unlawful use of a weapon by a felon (Class 3 Felony), one count of aggravated unlawful use of a weapon (Class 2 Felony) and one count of unlawful use of a weapon (Class A Misdemeanor).

Dunne was transported to the Kendall County Jail and bond is set at $75,000.
