A 17-year-old boy was arrested after being found with a loaded gun, modified to be fully automatic, during a traffic stop in Zion where a second armed suspect fled from police.

The Zion Police Department conducted a traffic stop on a white Nissan Altima for traffic violations near 29th Street and Bethel Boulevard around 4:49 p.m. on October 24.

Officers developed probable cause to search the Nissan and removed the occupants, according to Zion Police Department Lt. Derek Zaloudek.

Officers noticed what they suspected to be a firearm underneath the clothing of a 17-year-old boy, who was one of the passengers.

Zaloudek said they confirmed the juvenile was in possession of a black and brown Glock 9mm handgun, which had a magazine holding 30 rounds of ammunition.

The Glock was modified to allow for fully automatic firing, Zaloudek said.

Officers were arresting the 17-year-old boy when an unidentified passenger fled from the scene.

The suspect discarded a black unserialized 9mm handgun, which had a magazine holding 12 rounds of ammunition, while running from officers.

The driver, a 16-year-old boy, along with an 18-year-old male passenger, were released from the scene without charges, Zaloudek said.

The 17-year-old boy was transported to the Zion Police Department and charged with multiple felony offenses of unlawful use of weapons, including possession of a modified firearm and aggravated unlawful use of a weapon under 21 years of age.

The juvenile was then transported to the Robert Depke Juvenile Complex Center in Vernon Hills.

He was released the following morning to family members with home confinement stipulations pending court proceedings, Zaloudek said.

“Investigative efforts are ongoing to identify the other passenger who fled, and charges are pending,” Zaloudek added.
