Bond Set at $25,000 for Oswego Man Accused of Illegally Possessing Weapon Altered to Fire as an Automatic Machine Gun

(The following is a joint release from the Naperville Police Department and the DuPage County State's Attorney's Office.)

DuPage County State’s Attorney Robert Berlin and Naperville Chief of Police Jason Arres announced today that Judge Brian Telander set bond at $25,000 with 10% to apply for an Oswego man accused of possessing a weapon that was modified to fire as a fully automatic machine gun. Caleb Davis, 18 (d.o.b. 1/11/2005) of the 400 block of Treasure Drive, appeared at a bond hearing this morning where Judge Telander denied the State’s motion to deny bond. Davis is charged with two counts of Unlawful Possession of a Weapon – Loaded Machine Gun on Person/Possession in Passenger Compartment of a Motor Vehicle, a Class X Felony.

On June 29, 2023, at approximately 9:03 p.m., officers with the Naperville Police Department observed a vehicle drive to a dimly lit area of a parking lot in the 2700 block of W. 75t Street and park the car. Officers approached the vehicle, allegedly being driven by Davis, on foot and allegedly observed the butt of a firearm protruding from the feet of the passenger in the front seat. Both Davis and the passenger were removed from the vehicle at this time. Upon searching the vehicle, officers allegedly found a loaded Glock 9mm handgun with one bullet in the chamber and thirty-four bullets in the magazine between Davis and the center console. The Glock was modified to allow the gun to fire as a fully automatic machine gun. The passenger in the vehicle possesses a valid Firearm Owners Identification Card and a Valid Concealed Carry License. Davis was taken into custody at this time.

“It is alleged that Mr. Davis, who did not possess either a FOID Card or a CCL, was illegally in possession of an illegally modified weapon,” Berlin said. “I commend the Naperville Police Department for their heads-up work in this case that took a very dangerous weapon off the streets. I also thank Assistant State’s Attorneys Rob Willis and Anthony Raimondi for their efforts in securing strong charges against Mr. Davis.”

“As demonstrated by this incident and other recent arrests, this department’s proactive efforts to seize illegal weapons will continue to be a priority to keep our community safe,” Arres said. “In this instance, the firearm was modified to make it fully automatic, which is extremely dangerous and highly illegal. Who knows what tragedy our officers may have prevented by removing it from the streets and arresting the person who allegedly possessed it? I greatly appreciate their efforts and am thankful for the collaboration we share with DuPage County State’s Attorney Bob Berlin and his office.”

Davis’ next court appearance is scheduled for August 21, 2023, for arraignment in front of Judge Brian Telander.

Members of the public are reminded that these complaints contain only charges and are not proof of the defendant’s guilt. A defendant is presumed innocent and is entitled to a fair trial in which it is the government’s burden to prove their guilt beyond a reasonable doubt.
