New Milford Police say the loaded 9mm pistol with no serial number found in a car at the High School Tuesday was allegedly obtained on the streets, without the parents’ knowledge. The 17-year old's parents will not be charged. The so-called ghost gun was discovered as police investigated a fight in the bathroom. New Milford Police say the gun couldn't have been bought in a store and wasn't registered with a serial number so it was classified as illegal under state law. Anyone who manufactures a gun is required to obtain a unique serial number from the Department of Emergency Services and Public Protection. The teen was charged with criminal possession of a firearm and possession of a ghost gun. Police are continuing to investigate how the teen obtained the weapon.
